What is every one achieving with this ram?

Im planning on buying a 3570k.

If I bought this ram, entered the bios set the ram too:

- 2400MHz (11-11-11-28 1N) @ 1.50v

Does it affect the way the cpu gets overclocked?

As in would I just go about increasin the speed and the vcore, until I reach max safe heat or voltage? Leave LLC and other things on auto I presume?

And what are these values?

None of the CPU I have take a hit on overclocking at 2400mhz RAM speed. Each IMC is different though. Its when you get above 2850mhz that you need more Vcore to actually attain high CPU and RAM clocks simultaneously. I achieved 10-12-12-24 1T straight up on these sticks in MVG. Then went 11-13-13-25 1T for 2600mhz. Its not as easy as plug and play though with most systems your gonna need to tweak the settings abit. Which board you getting??

AUTO settings for things like LLC are ultimately probably not going to be good enough, you will need to set these and test accordingly.
 
2500K, Maximus V Gene (MVG), 16GB Samsung Green, straight in at 2133MHz 10-10-10-28 1T @ 1.50v. Memtest ok for two cycles so now looking to tighten timings and/or lower volts.

I had doubts about this stuff running 4x4GB 1600MHz @ 1T, let alone 2133MHz, but no problems whatsover so far. Is it worth pushing for higher MHz on a 2500K?

Thanks for the MVG recommendation 8 Pack. Great Mobo and RAM combo:).

What board do you recommend.

I would spend as muich as £120-£130 on a Z77.

I was going to buy Gigabyte Z77X-UD3H not for any special reason.

Only thing that draws me is 8 pin power connector and its Gigabyte.

I'v had good experiences with them in the past, so am comfortable sticking.

I see there are some much cheaper boards on the OcUK website.

Any pf them good enough?

Sorry did not register that 24 its been a long day!!! I have not tried 2000 mate. Look at my 2133mhz SB timings and dial down from that. I would say from mine for secondarys I would look at possibly ref cycle 96, Read to pre 3 or below, Four act win 22, Try DRAM clock period of around 6 also. I would leave TRAS at 24 for now then and concentrate on the others first as 24 is OK. Enter your thirds as mine but with SR from 6 to 5. Then tweak from that.

Cheers :)

But... arrrrrghhh i wanna push for at least 10-11-11-24 1T @ 2333MHz again now :p:D this RAM is addictive!
 
Well I didn't get any further with your settings last night 8Pack, although I did get distracted as my 7970DC2 arrived yesterday afternoon so was messing around with that.

I copied your settings exactly, made the changes you suggested for using 4 sticks, went up to 1.65V, dropped to 2T. No joy so went back to bed :) I'll keep trying tonight and maybe even drop to 2x 4gb and loosen timings some more. I guess maybe my P8Z77-V Pro doesn't have the ability of yours?
 
you could have a poor clocking set?? running 8gb just fine on z68 v pro 1.55v

are they matching batch numbers on all the modules? four digit number

That could be exactly it mate the MVG is built for clocking RAM and has had many bios revisions to do so. Also remember I am estimating settings as I dont have four sticks of that RAM (yet) I am gonna get some more to try it soon. Finally each CPU has a different memory controller and likes slightly different settings. Keep going I am sure you will get somewhere. When I get more sticks I will post back some settings. A friend of me had some Team DDR based on Samsung IC I got this to 2875 stable on my board with 4 Dimms installed. The Team dimms are selected IC's though.
 
One area of pc overclocking I am completly clueless on is ram, and its relationship to the CPU overclock.

Would you say this is still the best price/performance ram to get.

With other ram sticks which are set at say 1866, do you just plug them in and they work at advertised speeds or do you still need to go in to bios and set timing etc?

Is 2400 at 1.5v unrealistic?

Whats a more realistic, put it in, go to bios, set timings, speed for these sticks?
 
It seems to be a little dependent on the platform at the minute... but hopefully that'll get ironed out with bios updates.

But yes, this is by far the best price/performance ram out there at the minute... especially if you plan on clocking it - it has so much headroom!

2400 @ 1.5v is possible, yes.

Other RAM you may still need to do a bit of fiddling like enabling XMP in the bios - if your platform supports it of course - but with XMP enabled then it does it all for you.

When you say 'possible' does that mean after setting the timing, I would need to stress test it?

And setting these speeds, doesnt affect the overclockability of the cpu?
 
I say possible because I haven't done it myself - just read about what others have been acheiving.

On my MSI Z77A-GD55 I can't get 4x sticks to POST at anything above 2000MHz... but I believe this is a bios compatability issue which will hopefully be resolved.

What platform are you on? I'm assuming your sig is out of date as I don't think there ever was DDR3-800 so your sig would suggest that system is running DDR2.

But otherwise yes, always stress test an overclock... you don't have to do it for hours on end, 20 mins in prime 95 should be enough.

Overclockability of the CPU - again, very much depends on what platform you'll be using them on.

If it'll be paired with a 2nd or 3rd gen i7 where the BCLK is left at stock and the multiplier adjusted to get the overclock... then no, overclocking the ram will have no bearing on the CPU O/C.

Just be aware that it's not the best idea to start overclocking both simultaneously as it'll make tracking down an issue harder... overclock one at a time, then put it back to stock and overclock the other... once you've found a stable clock for both CPU and RAM seperately... then punch both sets of figures in :)
 
I havent bought anything yet. Im planning on getting:

3570k
8Gb of this ram - this is open to recommendations.
Noctua cooler - this is open to recommendations.
Gigabyte Z77X-UD3H - this is open to recommendations. I like it as its gigabyte (hada good experience with them in the past, and it supports both sli/xfire as well as 8 pin power connector.
GTX 670
 
i think its fair to say 2400mhz on p67/z68 isnt possible 2133mhz is more realistic imo,with dram voltages ranging from 1.55v to 1.65v

with z77 and x79 you can expect to run at 2400mhz and higher with dram voltages from 1.55v to 1.65v+ depending on how high you want to push things ect

I recommend ASUS MVG Z77 but this is the only Z77 I have used great for clocking RAM and CPU. Very stable!!! Its above your price band slightly though. At that price point I cant help I am affraid.

This is not exactly true at High DRAM overclocks and High CPU overclocks. e.g With no CPU overclock on Ivy DRAM overclocking can reach DDR3065. With a CPU overclock also a high one at that I have to drop my RAM speed to around 2875mhz with full population for stability to bench. This is of course because the IMC is now on die and one effects the other evan if its just the extra heat in the area from having to use higher VCCIO to attain higher DRAM clocks. My top CPU overclock for benching is 6ghz but at this I can only bench at DDR2600 what you have to do is work out the correct balance of CPU overclock and DRAM overclock.

For most at 4.6ghz DDR 2400 it makes no difference though. With no cpu overclock you are no where near the limit of your specific cooling so DRAM will go higher. At high clocks the IMC becomes flackey with too much extra heat.

Looking at the pics of that board though - seems it could be a tight fit for full-size graphics cards in crossfire/SLI?
