i7 with 12GB RAM

i have 12 GB of Corsair Dominator Ram @ 1600mhz which is stock, you just have to manually set it in the bios, in my experience it runs sweet at as nut with my i7 920, im using the ASUS rampage extreme mobo...

People who are having stability issues trying to run 12 gigs of RAM with and i7, would you mind telling me what issues you are having ? Ill try the same tests on my rig and see if i run into any issues i may have overlooked but so far everything is stable according to memtest and prime95.

Hope this helps... here is a thread with my bios settings too as i know some of you were looking for that and i wish i could have found some when i built my rig :D hope it helps..

Hi Plec :) Thanks for the warm welcome and quick response.

When's the single PCB 285 coming out?

I originally chose to go with 6GB myself but when I remembered that the VMs are gonna be running, I realised I'd need more. Would've settled for 8 but then tri-channel setup doesn't allow that so I stuck with 12 :p

I considered getting an SSD as well for the OS but here in NZ, the prices are insane :eek: Thing is intending to use the 500GB to dual boot Windows 7 and OSX 10.5 and have all the installed apps on it. The first 1TB is dedicated for the VMs (which would be work and uni related) and the second 1TB is for storing all my music, movies, games, softwares etc.

Yeah, I can agree with you on the memory speed front. A mere difference of NZD 20.00 is negligible. And yes flexibility is always welcome. As for the 6GB running at full native speed, I'm not entirely sure because I checked the Intel site and it said that the i7 doesn't "officially" support speeds greater than 800/1066MHz :confused:

I guess it call comes down to some info I found on Wiki and the Intel website. The core i7 has the memory controller on-chip as you all might be aware, but it's designed to handle at most 32GBps memory bandwidth (check here http://www.intel.com/technology/quickpath/demo/demo.htm). From Wiki (http://en.wikipedia.org/wiki/List_of_device_bandwidths#Memory_Interconnect.2FRAM_buses), I would guess that PC3-12800 (=1600MHz) in tri-channel exceeds this limit of 32GBps and hence the RAM runs slower (tri-channel 1333MHz might just be pushing the bandwidth boundary which is why the magic frequency of 1066MHz).

Thanks for the pointer to the CPU forum,I'll try there :)

Hi Hikari Kisugi :) Nice setup there. Are you actually running your RAM at the 1600MHz frequency? As mentioned, the RAM would have been de-clocked to 1066MHz unless overclocked.

Hi turboduck :) Thanks for the info and the link. I've bookmarked it. I'm sure it'll come in handy when I build my rig :D

That's something i don't know (or even if they intend to) - i fluked finding out about the 295's when researching my friends build a few weeks ago.

Hi Hikari Kisugi :) Nice setup there. Are you actually running your RAM at the 1600MHz frequency? As mentioned, the RAM would have been de-clocked to 1066MHz unless overclocked.

I've just responded to one of Hikari's other posts requesting his memory specs as he is running 12gig at 1600MHz on a P6 V2 - the very board i've sourced for my friend.

Technically anything over 1333 is overclocked but if only running 6 gig the mobo should have no problem attaining the memory's rated speed. And if you get the right combination of memory/mobo it seems that it is more than possible to get 12 gig running at it's true speed too. Obviously, it may take a bit of tweaking but some ppl are even getting high clocks and running their memory at 1600MHz and over…

I suspect the above is achieved via a combination of lots of compatibility research, BIOS skills, studying other rig setups and the luck of your components flexibility …
 
Interesting about the 295, I had a look and couldn't find much info either.

I never thought of that, as I mentioned about the memory controller and bandwidth, I was under the impression that the speeds always limited to 1600MHz. Guess I was wrong :p

Totally agree with you there. I've been researching for the past month now, still need more info before I build. Read good reviews about the Gigabyte board and its coming fairly cheap so decided to settle for that. Just came across that RAM and OCZ I believe is a good manufacturer so settled for that. :D

You're not wrong - sorry, i didn't phrase that paragraph very well.

You do need to set the mobo so that the memory doesn't run at 1066 by default. I meant that most ppl will expect to get 1333MHz by default - but anything over that may be a bit of a lottery depending on memory/mobo combos and the amount you have installed.

But your exactly right - anything over 1066MHz is, technically, classed as OC.

You might find this thread - link - of interest, if the OP experiments with the Asus Rampage, as he's getting some interesting results with memory and board combos.

Ah right, had a feeling :p Interesting thread link. I just found out that the REII costs about $250 more than the board I'm getting and that's pushing my budget a whee bit too far :(

Thanks for the 295 link. Seems like a fantastic card to own! But I think I'll be fine with a 285 (I'm not so rich afterall :p)
 
If it were my own build i would be sticking in a 285 or a 4890 - but my friend has money to burn.

TBH, it makes the build very intersting for me as i very rarely get to work with cutting edge gear - so it should be a laugh to build and subsequently benchmark. (as long as the build goes smoothly, of course.)

Good luck with yours - let me know how you get on.
 
max i have had on the cpu with 12gb of ram is 4.3GHz on a rampage extreme 2 with 12gb of dominator @ 1400mhz using an i7 965

it can be done but like w3bbo said - it is dependant entirely on the chip

Well my system setup is somewhat odd currently. As I am running my processor at stock speed until a noctua cooler arrives. This is probably making my memory specifications easier to work with.
My 12Gb is set to OC, and thus does run at 1600MHz, alongside the stated timings of 7-7-7-20. Additional to this, I did check the QVL list for the Asus P6T Deluxe V2 prior to purchase of the memory. It allows for 6GB to be used in eitehr of the 3*2 setups, and thus in my case allows for all slots to be filled.

When the noctua arrives I'll have to reconsider my memory speeds, as I will intend to ramp things up elsewhere, and that might likely involve sacrificing memory speed.

Everest reports my memory modules as OCZ XTC Platinum OCZ3P1600LV2G

Hope this is of some help.
 
Thanks for the comprehensive reply, Hikari Kisugi. My friend isn't keen on clocking straight away, although i am, so your memory specs will prove useful, thanks.

Post back when you've experimented with the Noctua attached - as that is the HS i've chosen - and it will be interesting to see how you get on.

Your clock and memory ratio make for encouraging reading and coming from a very credible source gives me hope that i’m not just clasping at straws in finding the right memory/mobo combo – although it’s becoming increasingly evident that the chip is head honcho…

What’s your preferred mobo for the i7 chip?

I’ve replied to your other thread here – link – have you made a decision on whether or not to use the REII on the i920 setup? (Can't really blame you if you've decided to leave your current setup alone - although i doubt you will for long ;))

To everyone...sorry for the late response...had a couple of exams and got caught up...hope those two went well :)

@Plec... Yeah I'd agree with you regarding the 285 or 4890. Although, personally I'd choose the 285. I dunno, just am a little inclined towards nVidia *hides* :D Thanks I will keep everyone posted, but gonna be hopping around here still. Good to be among you lot.

@rjkoneill... Those are nice numbers really. I'll be getting an i7-950 with a Gigabyte GA-EX58-UD5. Let's see what performance I'll get running the RAM at 1066MHz :p

@Hikari Kisugi... Thanks for the info. That sounds promising :) Does your system run stable with stock CPU speed and OC'ed RAM? And would it be possible for you to post your voltages by any chance? Also, what does your system run like? (not stability but performance wise)

@Plec... Out of curiosity, what's your setup?
 
Good luck with the exams!

@Plec... Out of curiosity, what's your setup?

My main setup is in my sig – I set out to deliberately build on a budget as I wanted to experiment with the E5200 and see how much bang-for-buck I could get out of a Dual Core System upgrade. Plus, i new i would be building a HTPC this year and the E5200 will do the job nicely.

It’s proved to be the most economical and giving ‘semi-build’ I’ve done. However, I took my experiment a bit too far and I regret not getting RAID and the 4870 and so will be rectifying this with my new build in the New Year – which will probably be based around the i7 or i5 release and a 285/4890 or 2. (I may treat myself to an SSD).

In the interim, I have a NAS to build and an HTPC, which will probably be b*stardized from a lot of my existing kit. (Plus a modded Topfiled (PVR) which now needs the capacitors changing.)

The build I’ve mentioned in this thread is for a friend who wants an 'all-singing all-dancing' system. I’ve actually reigned in the below build...

His pending spec (for now – waiting on Single PCB 295):
  • Intel Core i7 920 D0
  • ASUS P6T Deluxe V2 (or the REII as it’s dropped in price since compiling this build.)
  • BFG GTX295 1792MB (Hopefully, a single PCB version – if they’re ever rleleased :/)
  • Silverstone Fortress FT01B-W Black Case
  • Noctua NH-U12P CPU Cooler
  • HP LP2475W 24" TFT Monitor (I love this monitor!)
  • OCZ 6GB (3x2GB) DDR3 1600MHz x2 (Still looking hard at this – I’ll probably throw in what Rjkoneil has been using on his setups – as he does it for a living and knows what’s likely to be most compatible/flexible.
  • Be Quiet 850W Dark Power Pro Modular PSU
  • Western Digital 1TB Raid Edition III SATAII 7200rpm x 3 (RAID 5 OR 0)
  • Maybe an SSD – but he wants a large version and even he can’t justify the price of a 250gig SSD!
  • Insanely priced G19 (not keen on them myself – I prefer the Logitech diNovo Edge)
  • And I’m trying to persuade him to buy a decent 2.1 system rather than a compromised 5.1 setup as the room he’s setting it up in would benefit more form a quality 2.1 system.
  • And that’s about it – perhaps a quality sound card but I’m not mentioning that option if he insists in getting the 5.1 speakers – I would rather he splurged on a small SSD as he would benefit far more.
I’m looking forward to building it – the one draw back is that I suspect it will give me the urge to upgrade now. I have no need - as my rig does all that I ask of it – but I suspect that when I witness the raw power of the above build it will be very hard to resist.

Having said that, I have kids that reign my spending in – they seem to have this ability to absorb money…
 
Hey Plec...thanks again :)

That's a good experiment, cost effective and still a decent bit of hardware overall. Look forward to your HTPC build :D

Speaking of RAID, I was considering going in for a RAID 1 setup myself but felt it would just mean buying more hardware and bumping up the price. Would you recommend going in for RAID? And what would be your reasons for or against it?

Good luck with the SSD, that's going to be ripper :p

Maybe an SSD – but he wants a large version and even he can’t justify the price of a 250gig SSD!

Is there anyone at all you know of who's got a large size SSD? I read somewhere that those things are super fast to begin with but as they fill up they do become slower - slower infact compared to standard spindle based HDDs actually!

Your friend must have some serious money to get something like that :eek:

HP LP2475W 24" TFT Monitor (I love this monitor!)

The monitor indeed seems really really good, numerous input sources and great picture quality. I'd go for it too if it wasn't for its killer price tag (nearly 3 times the cost of the one I'm intending to buy - Viewsonic VX2433WM).

Insanely priced G19 (not keen on them myself – I prefer the Logitech diNovo Edge)

Yes the G19 is kind of overkill. I'd concur with you regarding the diNovo Edge, although I chose the Illuminated Keyboard for simplicity lol.

As for the sound setup, I'm choosing to go with Logitech X-540. Read around a bit and turns out they are a pretty decent set of speakers. What do you think?

Personally, I wouldn't bother with a sound card either really. The integrated sound chips are pretty decent now a days. Also a proper deck is all you need to get serious sound. Oh and rip your music at high bitrates ;)

Now, I just peered into my crystal ball and it says that the chances of you upgrading because of your friend's rig are rather high :D

Haha, I have a long way to go till I have kids, but, would I be right in drawing up an analogy along the lines of: kids = upgrades just about every single day?
 
Speaking of RAID, I was considering going in for a RAID 1 setup myself but felt it would just mean buying more hardware and bumping up the price. Would you recommend going in for RAID? And what would be your reasons for or against it?

I had a crude RAID 0 setup made up of 2 drives with 2 other drives as backup and storage – it was a half hearted effort really I should have really setup RAID 5 or ghosted the RAID 0 set up…

RAID 1 is, obviously, one of the safest options but if you can stretch the budget RAID 5 is a nice compromise for both speed and safety – trouble is you need a minimum of 3 drives for this and so becomes expensive – but it’s always something you could do at a later date when you’re comfortable with your new rig.

I can’t really think of anything against using RAID 1 other than financial constraints. It’s added security for your DATA plus if one drive dies – you'e up and running again within a few minutes.


Good luck with the SSD, that's going to be ripper :p

Hehe, if I hadn’t already noticed you were antipodean from your location tag – the ‘ripper’ euphemism would have given it away for sure. :)

Is there anyone at all you know of who's got a large size SSD? I read somewhere that those things are super fast to begin with but as they fill up they do become slower - slower infact compared to standard spindle based HDDs actually!


No I don’t and, your right, this seems to be the case – especially as frequent defragging is not advised. That coupled with the price is why most ppl are opting for the 30gig vertex – as it has software which can apparently restructure the drive to run at optimal speed again – something along those lines anyway. Some ppl on these forums have 3 or more set up in RAID0/5 and are having great results/fun.

The monitor indeed seems really really good, numerous input sources and great picture quality. I'd go for it too if it wasn't for its killer price tag (nearly 3 times the cost of the one I'm intending to buy - Viewsonic VX2433WM).

Yes, I want one but I’m going to content myself with either the DELL utrasharp 22” or the DELL 24” TN panel as I’ve seen it in the flesh and it’s a great panel for the money. (I buy DELL as their pixel/returns policy takes the hassle out of buying a TFT.) Having said that, I’m typing this up through my aging but very capable Viewsonic while working on my other screen.

I haven’t read any reviews of Viewsonic VX2433WM – but I’ve just googled the spec. It reads like a gaming panel (2ms response) is that what you’ll be primarily using it for?

Yes the G19 is kind of overkill. I'd concur with you regarding the diNovo Edge, although I chose the Illuminated Keyboard for simplicity lol.

If you mean this one –link – this is the other one I tried to persuade him to get as it would be in keeping with the clean lines of the rest of his build – but my tastes shouldn’t really take over his build (although I insisted on the Silverstone Fortress.)
As for the sound setup, I'm choosing to go with Logitech X-540. Read around a bit and turns out they are a pretty decent set of speakers. What do you think?

Sound is very subjective and is very dependent on your room and system setup. But, you can get too caught up in that malarkey – and if you have the room to set up the 5.1 speakers correctly - i.e. and not stacked on top of each other - then the Logitech X-540 are great quality for the price – and will serve you well for all round entertainment usage.

Personally, I wouldn't bother with a sound card either really. The integrated sound chips are pretty decent now a days. Also a proper deck is all you need to get serious sound. Oh and rip your music at high bitrates ;)

I too use the onboard as I find them adequate for my needs – they’ve come a long way and do the job.

Haha, I have a long way to go till I have kids, but, would I be right in drawing up an analogy along the lines of: kids = upgrades just about every single day?

Your analogy may be proved right in a few years time – although they won’t be touching my systems. At the moment they absorb money through – clothes, toys, nappies, furniture, decorating – redecorating that which you just decorated because they’ve trashed it again – I could go on…

Yea that's something I should look into at a later date - RAID 1 minimum if not RAID 5 (the P193 supports max 6 drives). I'm sure I'm not that destructive :p

No I don’t and, your right, this seems to be the case – especially as frequent defragging is not advised.

Why is defragging not advised? Also, the 30GB Vertex that you are talking about is a good little SSD but just thinking about it, don't you need like 40GB minimum on your drive to install Vista/7?

It reads like a gaming panel (2ms response) is that what you’ll be primarily using it for?

I won't say gaming would be the prime purpose, although I will be using the rig for gaming too (hence the 285). I mainly play FPS, driving simulation and strategy. Essentially, I was after a screen on which I could multitask easily (screen realestate) and have a decent output for watching HD movies and stuff as well. I happen to have an Xbox 360; so I guess there are chances of me being able to play some games using the Viewsonic maybe. Also would do some basic graphics (PS) stuff so the lot really.

If you mean this one – link – this is the other one I tried to persuade him to get as it would be in keeping with the clean lines of the rest of his build

Yes that is the keyboard I'm talking about. It seems to be pretty decent simplistic keyboard. Backlight was something I wanted so that I would operate my keyboard at night when I decide to stay up late and play games or something sometimes lol :D

but my tastes shouldn’t really take over his build (although I insisted on the Silverstone Fortress.)

I can understand your position. Is your friend a pro-gamer or really fond of using macros? No offence in asking that but really those are the only major advantages of getting that a keyboard like that.

if you have the room to set up the 5.1 speakers correctly - i.e. and not stacked on top of each other

I have decent enough shelf/table setup that I could place my speakers facing me something like this:

roughscheme.jpg

This is a face on view. I know I'm going to be running short on space so the end setup may differ once I build the rig and place things on the table. (excuse the use of paint because I was just trying to be minimalistic and quick :o)

Wonder where I'll place the printer and scanner though :confused: Better get one of those L-tables sooner than later.

Your analogy may be proved right in a few years time... At the moment they absorb money through – clothes, toys, nappies, furniture, decorating – redecorating that which you just decorated because they’ve trashed it again – I could go on…

Oh yes, still must be a joy I reckon :) (to a certain extent :p)
 
Why is defragging not advised?

From the little i've read - it apparently wears out the drive prematurely – so it's not advised to do regularly.

Also, the 30GB Vertex that you are talking about is a good little SSD but just thinking about it, don't you need like 40GB minimum on your drive to install Vista/7?

Well if you follow Microsoft’s party line it is, as they suggest 20 gig for Win 7 64 bit – but i would have thought 2 x 15gig partitions would be ok. For example, my last Win 7 64 bit install only took up 8.4 gig of space. Plus once you get used to Win 7 you’ll drop Vista - if compatibilty issues aren’t an issue. (which is the only reason i’m running a dual boot system of XP Pro and Win 7 – but i find that i’m in the Win 7 environments 99% of the time.)

I can understand your position. Is your friend a pro-gamer or really fond of using macros? No offence in asking that but really those are the only major advantages of getting that a keyboard like that.

Nope – he just likes the look of it – i doubt he’ll use half the features.

I have decent enough shelf/table setup that I could place my speakers facing me something like this:

Your setup looks ideal – at least you’ll be positioning the speakers so that you make use of the surround sound.

Oh yes, still must be a joy I reckon :) (to a certain extent :p)

Yeah, it is a joy – i’m glad i got talked into it ;) – they really are great kids, i’m very lucky.

Ah overlooked those details :eek: I'm using Windows 7 too (on my laptop though which has gone for repairs :() What do you do about your applications? Install them on separate drive? I certainly am on the way to drop vista, 7 is quite welcome (albeit not a major change).

Nope – he just likes the look of it – i doubt he’ll use half the features.

One expression: *sigh*

Brilliant! Just need to sort out some wood to get a decent output from the sub :D

Yeah, it is a joy – i’m glad i got talked into it ;) – they really are great kids, i’m very lucky.

Slight lol but very lucky indeed :)
 
What do you do about your applications? Install them on separate drive?

Yes, you just have to choose the custom install option and select your other drive/drives as destination.

Ideally, if you were using the one 30gig vertex, you would stick with the one OS and install your main apps on there too - such as office, photoshop and any coding software that you may use. Then install all files, games and, not so essential, apps on another drive/drives.

Fast boot times and opening WORD or Photoshop in under a second must never get old... ;)

I've yet to experience it - but i' looking forward to the time that i do.

Ah right that's what I thought too. It's crazy how I managed to fill my laptop's 250GB primary HDD with the OS and apps, took up over 100GB :eek:

Fast boot times and opening WORD or Photoshop in under a second must never get old...;)

Oh yes I totally agree. I wonder how long it would take to boot and open both with a standard 7k2 HDD with 12GB RAM. hmmm... The only apps that have opened in under a second from memory are Notepad, Calculator and I think Paint :D

8.3 seconds (over RDP if it makes a difference) for first load of the day. Second time was 5.4 and third was at 4.6.
