Corsair 1866 ram unstable

Dean11 · 09-11-2009, 02:51 PM

Just got a new i7 build with corsair tr3x 6gb 1866ram. I noticed it was running at 1066mhz so i bumped it up to 1866 but it blue screens with a hardware error under stress. The voltage was set to auto in the bios so i set it to 1.64v which is the recommended voltage for this ram but same problem. i dont really know what else to do apart from trying each individual stick to see if one is faulty?

Did you set the timing for what is default at 1866?

Dean11 · 09-11-2009, 03:15 PM

I didnt touch the timings they were left as default, do i need to set them manually?

Yes you need to set the timing. It probably has them set for whatever it was suppost to be at 1066.

ok i kinda dont know what im looking at here

on the ram it says 7-8-7-20 so im guessing it should be set to that but dont know how

what do i change in the bios?

Well the corsair ram I looked up (dependant on what you bought) says
@1600 8,8,8,24
@1866 9,9,9,24 or 9,9,9,28

all at 1.65v

Dean11 · 09-12-2009, 02:51 AM

the bios automatically changes the timings from 8-8-8-20 on 1066 to 9-9-9-24 on 1866. @TFT im not sure if you were looking at the right model, these are the ones:

see how they have 7-8-7-20 on them? should i set the timings to that?

StrangleHold · 09-12-2009, 02:56 AM

If that is your, it should be a 7-8-7-20 @ 2T with 1.65V

Dean11 · 09-12-2009, 03:48 AM

ok i set it to that but ran prime95 and it blue screened in 10seconds. Also the DRAM timing mode in the bios shows it as 2N instead of 2T is it the same thing?

Run Memtest tonight while you sleep to see if you have faulty sticks.
