CMT4GX3M2A2000C8 - Corsair Dominator GT 2000C8 on P67
This test is about popular Corsair memory CMT4GX3M2A2000C8 on P67 board. It's the same memory as 6GB ( triple channel, X58 ) kits so includes PSC chips and is rated at 2000 CL 8-9-8-24 2N 1.65V.
Testing platform is my daily pc:
ASRock P67 Extreme4 B3 ( L1.64A BIOS )
8GB ( 2 kits )CMT4GX3M2A2000C8 @2133 9-10-9-24 2N 1,60V
System ( Win7 Ultimate 64b ) on Corsair F60 SSD
water cooling on cpu+gfx , all other air
There is only 1 XMP profile 2000 8-9-8-24 2N 1.65V and most P67 boards should set it from auto to 1866. What is weird my board with beta bios is setting it to 2133 and all timings like for 2000

Nice job, thats some fine detective work there
Those are some serious numbers!Intel Xeon x5690 E.S.@ 4008Mhz, 1.27v

I noticed that there are sometimes questions about these kits ( 4/6GB version ) so I think it will be useful at least for some forum members.
If anyone wish some different clocks/timings then I can test it when I find some free time.
Tests are on ASRock P67 Extreme4 and these boards have poor memory timing options so it's hard to set memory faster but I bet that on MIVE or some other, more expensive boards it will work better.
Now both kits ( 4 sticks/ 8GB ) are running @2200 9-10-9-27 2N 1.65V, 2nd day without problems.

Old thread but I don't want to make new so will add some new results on this ram.
2515MHz 7-11-7-24 on FX-8120, memory on air , cpu on SS
and max clock so far 2853.4 MHz

Great results. Makes me want to beat on my kit some more. Keep up the good work!

Thanks, I wish to make some more on this kit but I think I will need something better than air cooling. I really like how BD is working with different memory IC ... just IMC performance is really poor

I have the same sticks and they are keepers. I'll have to post some results with this kit when I get a chance.

I had two of these sets and regret having sold them.Daily Driver: GA-890FXA-UD5 - Ph II X6 1090T - 16GB DDR3 1333MHz - MSI R9 280X Gaming Edition/HD 5670/HD6570 - Venomous X Black + G1238B12BBZP-00 - TX850V2 - CM 690 II Advanced

I have 10 PSC sticks now. All are rated for 2000 9-9-9 or 8-9-8 and are making 2400+ on AMD/FX and 2200+ on SB or X58 ( hard to say max as I had no luck to IMC and SB has limited memory multi ). ADATA 2000G Rev 2.0 are scalling a bit better with voltage but my brother has now all of my ADATAs so I'm using mainly GTX3.
4 of my GTX3 are making at least 2750+ while 2 are a bit better by about 50MHz.
Most new kits like GTX8 are expected to be handpicked Hynix or some other sticks like new Samsung IC so probably something better for max clock but worse for timings.

I know !! Thread resurrection
What sort of vdimm are you running for the max clocks ?

1.75-1.83V for my kits. For some reason all my 4 sticks are clocking worse above ~1.82V. They also like lower temps than most of my other PSC but I'm not sure what PSC IC/batch you have in your kit so you can check it at higher voltages.

Thanks mate they run 2400 7-11-7 with 1.75v Spi1m but bit 32m @ that voltage, may push to 1.8v and see what they can do.
