Problems with XMP profile

Last response: in Overclocking

I'm using the Gigabyte UD7 with F3 BIOS, i7 960 and the cas 8 1600 dominator 6GB set. I can run fine at 1066 and get through mem test, play games etc no problems. The second I switch to 1600 on the XMP profile, I get random freezes whenever I do anything after booting into windows 7 64 bit. My USB power also cuts out on the freezes and I cant use the keyboard after a restart untill windows has rebooted. I'm 99% sure temps aren't the issue. Real Temp and HWMonitor both look good.
If it is of any use, the error code I get on the mobo debug LED is 'C0', which apparently is 'CPU status flag test, CPU register test, memory refresh test'

I would be absolutely over the moon if someone could help me fix this so I can run at 1600! Please excuse me for not being able to work this out myself. I'm rather new to all this and although I have put in many hours trying to find out what the issue is, I don't seem to be getting anywhere.

Regards,

Why do you want to run at 1600 ?.....But if you want to do that, just set the RAM timings and mem multiplier (12) manually. However typical purpose of buying DDR 1600 is to make easier overclocks. I'm not as familiar with the 960 as the 920 and 940.

Your base clock is 133.33 .... which gives you a CPU speed on the 960 of 3.2 GHz and w/ a mem multiplier of 8 = 1066 RAM Freq

If your base clock is 150 .... which gives you a CPU speed on the 960 of 3.6 GHz and w/ a mem multiplier of 8 = 1200 RAM Freq
If your base clock is 175 .... which gives you a CPU speed on the 960 of 4.36 GHz and w/ a mem multiplier of 8 = 1400 RAM Freq
If your base clock is 200 .... which gives you a CPU speed on the 960 of 4.80 GHz and w/ a mem multiplier of 8 = 1600 RAM Freq

You can also change the mem multiplier to 10 and then hit 1600 RAM frequency at a more modest 160 BCLK.

There's a link to a video here where some dude hit 5.7 Ghz on a TV show w/ a 960.

Hello, my name is Ovidiu and I read your post about the problem encountered with XMP memory profiles. I got a same problem on a Gigabyte P67A-UD4, Intel 2500k i5, Kingston 2x4GB 1600MHz XMP X2 Grey Series . All is well when run on the frequency of 1333MHz memory, but when I activate profile1 1600MHz I have the same problem as you, the computer froze at different time intervals when i play diferent games. I want to know if you would have solved the problem and what causes that. Thank you.

You will continue to get bsods and errors until you adjust the dram voltage to vendors spec.
The dram voltage is 1.5v default until adjusted usually 1.6-1.65v is required for stability and advertised speeds and timings.
