What voltages to adjust for tighter timings?

post #1 of 27
Thread Starter 
I'm currenty running a watercooled 2600K @ 4.9Ghz 1.448v (Temps <75c loaded with LinX AVX) and I use a 4x4GB (16GB) kit of Corsair Vengeance 1899Mhz CL9-10-9-27-2T-1.50v kit.

The kit runs stable as a rock on 2133Mhz 10-11-10-30-1T-1.600v with 1.10v VCCIO. LinX / Prime95 / Memtest86+ stable for 12 hours. No errors.

If I change even ONE timing a single digit it will generate errors in memtest so it's obviously unstable.

However, which voltages should I change to make it do 2133 9-10-9-28-1T or something like that.

I do NOT care about Intel's recommended voltages and such since it's been proven time after time that they are rather low..
I would be happy pushing VDIMM up to 1.75-1.80v and I wouldn't mind 1.20v VCCIO either however, which should I adjust and to how much?

1.8 is pretty much the limit for DDR3 memory, anything over that and expect to fry the dims.

Vengeance is not known for being very overclock friendly. I wouldsay tthat you are at the limit of the sticks... But timings are typically dependent upon the DIMM voltage.

I pushed as high as 1.760v for the dimms and got 9-12-10-28-1T reasonably stable but still had a error in memtest after ~400% pass so i give up haha.

What version are your sticks? Should be printed on the sticker on the memory modules.

V5.12. Hynix CFR. It should be able to do ~2666 CL11 as the Dominators with V5.12 chips do this is well but I can't go higher in terms of speed due to Sandy's controller limitation.

Timing wise I know Hynix isn't real good but I really wanted at least CAS 9.

I binned the chips one by one to partially iliminate the memory controller and none of them can de 9-10-9-28-1T no matter the voltage on 2133. 2 will complete 200% memtest at 9-11-9-28-1T 1.7250v. The other 2 need 10-11-9-28 at 1.7250v.

None of them is capable to usefully run 2400Mhz. Not even with 12-13-12-30-1T 1.7500v. Unstable as hell or not even booting.

1866Mhz with all 4 in my system also fails to even boot properly at 8-10-8-24-1T.

But at 16GB 10-11-10-30-1T everything is stable as a rock on just 1.600v.

I got my eyes on a 2x8GB AData 2133C10 kit with Micron D9's.. They worth any? Lot lighter on the controller with 2 DIMMs and much better IC's.

Oh, I didn't realize you were using Sandy Bridge. That's really holding back those sticks as they're made for high clocks. CFR isn't going to do tRCD 10 at DDR3-2133 though, you're better off trying 9-11-10 at that speed.

Won't run that either as I said frown.gif Errors in memtest / is unstable in BF3 even at 1.7400v. (VCCIO @ 1.1375v).

I'll stick to these DIMM's at 10-11-10 until I find a proper 2x8GB kit like those D9 A-Data's.

Hmm.. Nope I haven't really..

Is there a big performance loss with 2T over 1T?
