Help Dominator CMG 2000 c8

[orso232]

Hi to all,
As in the title also for me is difficult to set my dominator kit on M4E.
First of all I've tried G.Skill 2133 7-10-7 and works fine.
With dominator i've tried some different setup, but the problem is still the same, booting @ 2133 8-8-8-24 1t I can run S-Pi 1mb but not 32mb, freeze at 2nd loop. vDram 1.8v, VCCIO 1.25v. Bios 1485
Tried to set manually 8-8-8-24 1t, 9-9-9-24 1t, with xmp and sub auto, with xmp and sub as Andre settings posted in other thread, and also with optimized default changing only dram multi and voltage. memory boost on and off etc etc.
I've had same problem on a Gigabyte Z68 UD4 B3, hoping to solve with M4E, can you help me? I need a good setup to take profit from my 5.8Ghz+ 2600k
Thnx in advance for your time

You won't run it on 2133MHz, you need damn good hyper set to run them on SB platform. I had the same problems, couldn't run cmg2000c8 no matter what voltage, put gtx2 and no problems with them. Same goes for ocz blade 2000c7 and cmg2000c7, no problems with them on SB

I've a pair of perfectstorm 2000 c7, 1st hyper, i'll try them

ya i have some Mushkin 998750's that won't boot on 2133 no matter what the voltage or settings are either.

Nothing also with old Hyper, 2133 8-8-8 similar to cmg 2000 c8 in dual channel. Tried also single channel, bios timings set manually to 2133 8-8-8 became 2133 6-6-6 in Win from Cpu-z
BTW, I'll try later with 1866 7-7-6
Last dubt, do you think that putting them under LN2 could help to reach 2133 or not?

My cmg were able to run 2260 C8 on 1.65v, but they were unable to run 2000C7 on 1.7-1.75v. GTX2 runs 2100 7-7-6 on 1.65v, so you can imagine what kind of sets you would need for it. That is on X58, on p67 gtx2 needs 1.7v for 2133 7-7-7,

I could run 8-8-8 2133 with one stick, but with two no way, even with 9-9-9.

LN2 COULD help, but you never know. Maybe some very high voltage + ln2 really could help, but if you don't try you'll never know

I'll try next week, with LN2 and 1.8/1.85v. Thnx

I think you'll have to use higher, as 1.8v didn't worked for me (on air) with cmg2000c8

It can be done with the right modules:



Corsair Dominator GT 8-8-8-24 DDR3-2200 Rev 2.1 @ 1.65V on the MIVE.

When the CPU is clocked high you will have to fiddle with "BCLK Skew" and also DQ and CMD/ADDR Vref - I use 0.495 for both channels. Do not increase VCCIO too far - I only use 1.075V for these speeds.

Thnx Raja, I'll try also this tips, but i'm quite sure the problem is hyper's quality, almost all 2200 c8 kit works, more or less, instead only some 2000 c8 kit works. BTW I like to try
