[LGA775] Board for Overclocking.

Don't know where you live, but you can usually pick up a Q9550 for around £150 a decent P45 mobo for around £50 and 4gb of PC-8500 for around £50 from eBay these days from sellers with reasonable feedback and posted Special Delivery.

Is there a requirement for Quad Core?

If you want a cheap upgrade path and eBay is viable then socket 775 is reasonable bang for buck, if you just want to improve your system a decent P45 board coupled with PC-8500 will still work well with your current 775 CPU.
 
I must have sold my q9550 to cheaply,:eek: Only got £120.00 for it on MM, albeit that was a year ago, was a great clocker as well.:o
 
I would also like to point out that none of you answered my latest queries!

can any one tell me that is there any performance decrease when one uses pii x6 with an AM2+ board or pii x4 with an AM2+ board??
 
Cmon sastusbulbas, you are not seriously suggesting someone spend £250+ on building a 2010 LGA775 system? :D

No, not quite, but if you had a limited budget or low income and intended using some 775 parts a bit longer, as individual items the above may have been alternatives as individual purchases over the following months allowing improved performance from what he has.

As far as I could see his motherboard was holding back the current CPU, if he got a new motherboard and wanted to OC he may find PC-8500 usefull, and if sticking with 775 but wanting to upgrade to quad without spending on a new system the Q9550 or Q6600 are an alternative. All second hand of course.

As a long winded example. Last year I was interested in upgrading, everyone agreed get a complete new system, I ended up sticking with what I had. Didn't miss the upgrade, guess it was not that important.

Again this year I was all set to buy a new system, an i7 Micro ATX system was what I had settled on, but other things came up and second advice stated stick with what I have, so I bought a second hand Q9550 instead. I would still like the i7 set up, but it's not going to change my life or offer the experience of a lifetime.

If I had sold all my old parts I may have ended up with enough money for a few beers and a takeaway, or maybe 4gb of DDR3.

I now have two 775 PC's based on the following core parts, built up and upgraded from basic core components over time with little impact on my cash flow. My intended i7 key components are not going to give me a massive performance per pound increase.

Light gaming HTPC.
Asus Maximus II Gene
Intel E8500 (passive cooled) (was going to be an E5200)
Corsair Dominator GT PC-8500 4gb (was going to be XMS2)
Powercolor HD5750 (passive cooled)

Main PC.
Gigabyte EP45-DS3P (started off with an Asrock 4coredual)
Intel Q9550 (started off with an E5200)
Corsair XMS2 PC-8500C5 8gb (started off with 2gb of PC3500)
ATI Sapphire Toxic Vapour X 4870 (started off with HIS 3850 AGP)

The Asrock and E5200 were bought to allow me a cost effective upgrade from my old Gigabyte/Sempron 3300 system. I am quite pleased with the performance gains throughout my budget upgrade path and have had fun playing around with the builds and upgrades :)
 
Hi sastusbulbas :)

No, not quite, but if you had a limited budget or low income and intended using some 775 parts a bit longer, as individual items the above may have been alternatives as individual purchases over the following months allowing improved performance from what he has.

I don't see it makes sense for bongas to sell off his old LGA775 CPU/Mobo/RAM(?) and buy a new LGA775 CPU/Mobo/RAM . . . even if he was to keep his older DDR2-400 I'm still don't think it is the best route forward to base a new LGA775 system around the older RAM? . . . . if it was DDR2-1066 then perhaps . . .

As far as I could see his motherboard was holding back the current CPU
Yup he seems to have a uATX Intel® motherboard with zilch overclocking options . . . "if" he had an overclocking friendly motherboard will can't ignore the fact he has 400MHz (DDR2-800) memory that will "limit" the potential overclock of a
Intel® Core™2 Quad Q9400

Intel® Core™2 Quad Q9400 (8x333) 2660MHz
Intel® Core™2 Quad Q9400 (8x400) 3200MHz


if he got a new motherboard and wanted to OC he may find PC-8500 usefull, and if sticking with 775 but wanting to upgrade to quad without spending on a new system the Q9550 or Q6600 are an alternative. All second hand of course.
Can you clarify please if you are suggesting that bongas:

  1. [Sell] LGA775 CPU/Mobo/DDR2-800Memory
  2. [Buy] LGA775 CPU/Mobo/DDR2-1066 Memory (used)

can any one tell me that is there any performance decrease when one uses pii x6 with an AM2+ board or pii x4 with an AM2+ board??
Hey bongas,

I don't have a lot of data to hand that compares an AMD® DDR2 system against an AMD® DDR3 system . . . what limited results I've seen suggests there isn't a great deal it it . . . at least for gaming . . .

i have never had a quad core before
Well we are still not sure if you "need" one or not but you certainly "want" one . . . so here are two "possible" options . . .

bongas.jpg


If you decide to sell off your old Intel® LGA775 CPU/Mobo/RAM and build a completely new "DDR3" system you don't have to take the AMD® DDR3 option listed above . . . there are other options (Intel®?) but the AMD® Phenom™ II DDR3 system is viable . . .
 
Hi Big Wayne,

Your £140 mobo/CPU makes sense if he needs a Quad. But I wonder if gaming, would an OC'd E7400/P45/PC8500 be quicker in some instances?

My own opinion is that he may get next to nothing for the components he has for sale, or he may get up to £50? If his budget and components are limited and he is unsure, a second hand mobo may be a viable short term improvement. Regarding the memory issue holding back the CPU, would taking that DDR2 800 elsewhere in an AMD system still be a bit of a bottleneck? If so would upgrading and keeping the DDR2 not be a sideways step?
If he has a budget for an AMD and DDR3 build it makes more sense, with options on dual, triple or quad core based on actual requirement and budget.

My own Gigabyte EP45 was £50 B stock and gave me reasonable OC'ing with an E6300 and 4gb of DDR2 800. I didn't get any interest in the Asrock mobo but could probably get up to £30 on ebay for it?
My own 4gb of PC-8500 was £50 off ebay and I may get £30 or £40 for the old PC-6400 stuff so my real world upgrade cost seemed quite reasonable. If I was to sell my PC6400 ram for £35 and my Asrock mobo for £25 my "new" 775 Mobo/Ram upgrades would only have cost around £40 and maybe less if I was lucky.

As far as I am aware the E7400 is still quite reasonable, if a Quad is not needed it can still OC well with a reasonable P45 board (up to 4ghz), if he can OC it he may find his desire for a Quad diminishes. It is certainly not unreasonable to keep the E7400 and eek more performance out of it, and if going that route buying PC-8500 and selling PC-6400 may not hit the pocket too hard and can be spread over time. Of course these sort of upgrades can also be sold on at minimal loss if it does not fulfill his needs.

Of course without a budget and intended use we could do this all day, if he can only afford a motherboard then it makes no sense buying into AMD and storing it for a while, if he has enough for a complete system and needs a Quad then it makes things simple and he may as well go AMD.
If he does not need a quad he may benefit more from a better dual core or triple core, but will going with AMD give tangible benefit and improvement over an OC'd E7400 when the system is going to still be running PC-6400 or will it be a sideways step? I don't see any point going dual core AMD2 with DDR2 in this instance.

Without a budget and intended use it's all just opinion and banter (not that I should be taken seriously) so I do think just upgrading to a better 775 mobo worthwhile at the moment, then selling his current mobo if possible and upgrading to PC-8500 and selling his PC-6400 to re-coup costs. Then re-considering how much of a gain Quad would give him, and re-evaluating a 775 Quad or new AMD Quad build.

Of course I may have had a different opinion if the above was not what I seem to have done over time, and if I had went with a complete AMD instead?

Hello bongas!

I have taken some points you made from another thread and am posting them here! ;)

Newest Question:

  • I can 'tolerate' my current CPU for a maximum of 1 year.
  • I am not happy with my CPU ,e7400 because whenever i play games such as Assasins Creed 2 , Dragon age Origins, even Splinter Cell Conviction; my CPU usage is 100%. For me its an anomaly.
  • Buying a used board is not appreciated so is the rams but i might buy a used CPU
  • MY BUDGET IS : POUNDS 180.

Well you certainly have plenty of options . . .which is the "best" for you only can be decided by yourself! :D

it's such a pity that your current motherboard does not allow overclocking because that would certainly help give your current DualCore a bit more useful life . . . a DualCore is plenty fast for a great many games but it seems there are a few games out (and soon to be released) that appear to perform much better with additional cores . . .

One game you mentioned (Dragon Age Origins) appears to be one of those games that performs a lot better once it gets additional cores . . . I can't find an example with an Intel® Core™2 Duo E7400 so instead I have picked a similarly powerful dualcore (AMD® Phenom™ II X2 550) placed it against a "humble" AMD® Athlon™ II X3



In this single example, even though technically "Core-for-Core" the AMD® Phenom™ II X2 is superior (faster MHz, 6MB L3 cache) it is outperformed by approx 47% by the TripleCore . . . I don't know why this is but it just seems that some games work better with "more" than a DualCore . . . whether that is a TripleCore or a QuadCore . .

Still we can't ignore that even the DualCore is producing 63fps which is playable . . . if you could overclock your chip more then perhaps it would be smoother still? . . . but sadly your mobo won't play! hmmmm

I think what I'm trying to say is . . . "if" you decide to move forward and buy some newer hardware then getting more cores is a more logical move than overclocking your existing DualCore . . . whether this is a new Intel® LGA775QuadCore, new Intel® LGA775 Motherboard and "maybe" new DDR2 memory vs new AMD® AM3 Chip & AM2+ with your existing DDR2-800 is entirely your choice . . . or indeed a complete new Intel®/AMD® DDR3 system! :D

The biggest problem I would say is your mobo . . . what a drag! . . . if it was overclockable I think most people in this thread would "agree" that your best move forward would indeed be a USED Intel® Core™2 Quad Q6600!

i have never had a quad core before
 
Reasonable words from Wayne there Bongas.

Regarding this, to quote Wayne from another thread (I think it more relevant to reply here).
sastusbulbas, I do believe you may be more concerned with "justifying" your personal upgrade choice than helping bongas "consider" his options . . in bongas original [LGA775] Board for Overclocking thread you were advocating he essentially sold off his LGA775 DualCore/Mobo/DDR2-800 and replaced it with LGA775 QuadCore/Mobo/DDR2-1066 . . . much discussion was had and a lot of time and effort was made by the various contributers . . . . your viewpoint has now been updated as a result of this previous discussion . . . I am not here to make you feel you made the wrong upgrade choice but instead to answer bongas questions so he makes the "right" upgrade choice . . . if indeed he upgrades at all!

I was not advocating your suggested opinion see post 26 above, and I have nothing to justify and I did not make the wrong choice, I chose this route instead of an AM3 or i7 rig as I felt it offered ME more bang for buck with the least amount of hassle I decided I wanted a Q9550 or Q9650 and some in this forum advocated it too. When I find the Q9550 and 8Gb of PC-8500 a limiting factor or loose interest I can still move on, it's second hand value won't be much less than I paid. At this moment in time I would have been even more of a muppet by trying to justify an AMD 1090T with 8gb or ram or an i7 930 system as pound per performance it was less value and more about me wanting a nicer bling system. It may still happen, but I have still to play around OC'ing my current P45/Q9550 with 8Gb of ram.
If I was to ask advice now about upgrading my current system and improving my gaming experience I would expect to see SSD and graphics crop up as more viable alternatives to current Quad i5/AMD X4 CPU/platform choices. But I like playing with kit as well so even if I decide to change I will have still had some experience and fun :)

Regarding your opinion of me NOT helping Bongas consider options, letting him know how my own experience went after being in the same situation as him and having experience with one of the choices he is currently considering may well serve to give insight into what he may expect by going that route, your own graphs in the thread linked below don't show upgrading old 775 kit to be a massive waste of time and money. And I am sure the Athlon II X4 you suggested offered less gaming performance than his current E7400 when Custom PC reviewed it. Considering the machine requirement is gaming I am surprised to see no consideration into graphics card upgrades. I don't know, but how would an OC'd E7400/P45/PC8500 with a better graphics card perform in games compaired to a new AMD Quad/AM2+ with his current GPU and memory? What PSU does he have and how will it perform OC'ing a Quad? Is a straight platform upgrade going to save time and hassle?

Bongas,

I think it is apparent I have been in your shoes, having went from Sempron and AGP through some unfashionable upgrade choices to where I am now. I always preffered getting the most out of what I had spent money on before moving on, I like playing with PC's it's an interest, a hobby, not a means to an end for me, and as such most of my PC upgrades have been funded by beer money or selling bike parts. I have no regrets over my choices nor would I have regrets buying an i7 930 OR 1090T based set up.

I wondered if I would benefit from a Quad, I have on a few occasions thought about buying a new set up but end up playing with cheaper 775 upgrades. Maybe I read too many Computer magazines such as Custom PC and read into things too much, but every time I do think of upgrading a few months down the line the proposed system is different from last and affected by what I have read in a magazine or forum, it's not chosen due to being so limited with my current system that I cannot live with it any more, nor is it related to spending money. I bought Dominator GT and the Maximus II Gene retail because I wanted to try them in a gaming HTPC with a low wattage CPU and passive GPU and had some 775 kit to swap around if it took my fancy. I didn't care if it was fashionable or stupid old kit past it and overpriced. That said I have not made any real use of the Q9550, can't even say anything about it's performance or benefits as yet.

I am not advocating a complete change to a new 775 system, just pointing out that upgrading the mobo may well be worthwhile in the short term if not going for a new platform till the end of this year or begining of next, that upgrading your memory won't cost much if you end up selling your old memory. Later on you can still try a Quad with this route if you want to. The price you pay for a second hand 775 motherboard, 775 Quad, or PC-8500 is pretty much the price you can expect back. Buying new 775 kit would be a waste. But your not wasting your money if buying a second hand P45 and/or PC8500 gets more from your E7400 and improves the user experience for the next few months.

That said, £100 is about a third of what you require for the move to a reasonable Quad AMD/AM3/DDR3 platform. If you do plan to move platform soon and have £300 or so to spend now it is a waste of time and money continuing with your current 775 and DDR2 components. If you are still saving, buying a 775 motherboard now may not affect things too much?

If you are positive you want a new platform, Quad, and for gaming, I see no point in sticking with DDR2 and using anything less than an AMD Phenom II or Intel i5. AMD seems better supported, i5 750 with Gigabyte very overclockable.

If overclocking, buying budget AM3 or AM2+ may well lead you back to where you are now, limited with a poor OC'ing motherboard.

Another thing to consider is the graphs on post 8 within this thread http://forums.overclockers.co.uk/showthread.php?t=18182722.
Look at the CPU's (I would put an OC'd E7400 in a similar area of performance to the listed E8400 at stock), specifically think about the prices of the Quad CPU's and real world noticeable performance differences. I believe those AMD X4 and X6, i5 and i7 results are with DDR3 and maybe the memory related benchies reflect this, would the X4 945 score less with AM2+ and DDR2?

Edit,

Remember if you spend around £50 on a 775 P45 motherboard, it may well sell later for a similar amount, you may get something for your old board, it will certainly be worth more and probably utilise better quality components than a budget AMD board.

If you spend around £50 on 4gb of second hand PC-8500, it may well sell later for a similar amount, you may get a reasonable amount for your current memory making actual upgrade cost akin to buying a takeaway meal, even if you upgrade to AM2+ with DDR2, PC-8500 is still better memory than your current PC-6400 so won't be a waste of money.

Buying new is a lot less hassle, more straightforward and more secure, it will cost more short term but comes with warranties and such. Buying and selling second hand kit costs money takes time and has risks. All of which makes a new platform more atractive! I myself bought PC-8500 second hand and never recieved it, I had to wait for a paypal dispute to settle before getting my money back, and due to this got a little insecure and ended up buying new to save hassle, Dominator GT as it was only a little more expensive than XMS2 and came with a fan. Though later I plucked up courage and got XMS2 second hand for £50 with Special Delivery.

Nice little comparison tool I guess, can compare the likes of an E7500 to an X6 1090T both at stock, I guess moving up to the likes of an E8500 or such may give a bit of an indication on how an OC'd E7400 will compare in some apps?

As you can see it shows even against the Phenom X4 and X6 processors some of the old school dual core and quad core 775 CPU's seem to give a respectable account of themselves without OC'ing. How much of a difference these benchmark variables equate to is probably not always noticeable in a home user situation. Certainly in the games tested none of them seem to be a considerable issue? We can see that media encoding and some multi apps make use of more cores, but games and general use are more close knit.

All we need now is a cost versus performance scale to evaluate value for money, performance per pound.

Can anyone explain what does this mean:

fast ram (e.g. pc2-1066) means you can set the ram speed, low at first, then overclock the fsb (which will increase the ram frequency) e.g
you set the ram to 533 (i.e. 1:1 with fsb) and overclock the fsb to 400, the ram will now be running at 800mhz etc. the key being the ram doesn't exceed it's rated speed and limit your overclock.


I found it on another forum.....from what i understand is that my ram wont be a bottleneck when i overclock my Cpu.
 
I ran my E6300 CPU at 4ghz with a 10x400 multi, my ram was at 400Mhz (which = 800 dual channel). I was unable to get a prime stable OC with this, but did not play much with voltage or northbridge settings. I also ran my 1066 ram like this with the same issues. I guess I need to sort out the finer tunings in BIOS.

I also had a 1.1 ratio, have never had that explained to me?

Was also given the impression that my PC-6400 would limit my OC. With PC-8500 you can have more options with multipliers which may on some systems prove more stable such as 9.5x440 = 4.2Ghz (ram then at 880). I think the OC overclock FAQ may describe such.

i am confused.....why the hell do i need pc8500 rams?????????

please can u clearify something: Is my current ddr2 value RAM a bottleneck for my CPU when i Overclock it ???????????????????????????????

PLEASE NOTE THAT I DO NOT WANT TO OC MY RAM.......I JUST WANT TO OC MY CPU @ 3.7GHz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

is there any way too keep the ram @800mhz or less and then OC the cpu to 3.7GHz.

Hello bongas,

I don't blame you for being confused, you are taking in a lot of new information, from multiple people, in multiple threads! :D

It is also hard for you because you are unable to tell if what people are telling you is right or wrong . . . total chaos really! :eek:

Let me just tell you . . . if you are sticking with your DualCore and intend to pick up a used P45 motherboard then your current DDR2-800 ram will not hold back your CPU overclocking! :)

  • Intel® Core™2 Duo E7400 (10.5 x 266) 2793MHz
  • Intel® Core™2 Duo E7400 (10.5 x 400) 4200MHz
However if you decide to take the route of picking up either a QuadCore Q9400 or a QuadCore Q9550 then your DDR2-800 *will* limit your potential overclocks
  • Intel® Core™2 Quad Q9400 (8 x 333) 2664MHz
  • Intel® Core™2 Quad Q9400 (8 x 400) 3200MHz
  • Intel® Core™2 Quad Q9400 (8.5 x 333) 2830.5MHz
  • Intel® Core™2 Quad Q9550 (8.5 x 400) 3400MHz
