**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)

I am guessing these batch numbers are YYWW. Mine are 1207 and 1210. I have kept them paired, though I have tried mixing them and I have tried individually.

I have managed to post at 2133MHz but it wasn't stable enough to run prime for more than a second, and 55 errored more often than not. This was at 11-11-11-28 1T @ 1.65v (iirc on volts).

I currently have all four sticks installed, at 1866MHz 10-10-10-25 1T @ 1.55v (again iirc) and have been running prime95 for towards 11 hours!

55 Means the RAM can make that frequency but needs tuning mate.
 
I have Sandy in at the mo. 2500K here are my settings for 2133mhz stable with tight sub-timings. Vdimm is 1.6v. If Sandy can do this Ivy with much stronger IMC can do it easy.

Those using 4 sticks for 2133 use my timings. But for the third timings put 3,6,6,5,5,5,4,4,5 down the page from TWRDR to TWWSR inclusive. MVG owners just put Latency Boundary of 12. Also for 2133 with 4 sticks 2T may be necassary but try keep other 1st's and seconds as tight as possible. Back on Ivy Weds as I have some more Sandy stuff to test tomorrow. I will post some Ivy 2600mhz settings up then and Bios pics of the settings and hopefully the same for 2666mhz which posted easy the other day but I had no time to test. Update!!! see below DDR2300 is easy on SB so I would use same setings for DDR2333mhz on IVY put main timings as 10-11-11-24-1T with the secondary and third timings as here. 4 Sticks the same but use my Third timings settings suggested in this post.

Hi 8 Pack thanks for posting all these settings there are really helpful, looking forward to more when you switch back to Ivy.

I'm using 3570K and P8Z77-V Pro, managed to get stable at 2133 with 11-11-11-28 1T timings (using 4x4gb) @ 1.45V with the CPU at 4.6GHz. Saved this as a profile and went for 2400MHz but had no joy. So I reloaded my working profile and now that won't post at all, I'm kinda baffled! Do you think its because I leave all the sub timing settings on auto and they have changed? (assuming they auto set each time I make changes?)

Going to try your 2133 settings when I get home from work, but hoping to get up to 2400MHz as I'm on Ivy.

Yes its due to memory training mate which is part of the onboard controller. Reset the Bios completely Load optimised defaults F5, F10 to save. Back into bios load the profile and your ready to go again. I would try the subtimings I suggest here also though. Or fill in your stable timings in the Bios If you enter values in all the DRAM Timing value of the bios it eleviates the small but sometimes important changes memory training may cause on boot up and any instability / problems booting associated. For Ivy and Sandy set the slews I have above these are important also set DRAM DATAref A/B voltage to 0.495 volts with IVY.

For 2400mhz Try 10-12-12-31 -1T main timings or possibly 2T I had this work first time with Ivy and then moved onto 2600mhz. The 31 can probably come down for performance to around 24. Set VCCIO t0 1.20 for 2400mhz and PLL to 1.7v. The Value below PLL needs to 0.4v cant remember exactly what it is from work!!!

I'm settling with 2000MHz @ 9-10-10-24-124-1 @ 1.55v for now. Can probably lower the voltage and tighten the secondary timings, but will concentrate on the CPU for a little while and come back to the RAM again later.

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?

That 28 is 24 @ 2000MHz (see screenshot), will go back to it later and get it down and try 22.

What do you suggest for te secondary timings @ 2000MHz @ 1.55v?

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.
