Never OCed before so would love some feedback on my first run. When I made changes, the temps wouldn't get too hot, but the PC could not pass Linx 20 runs - "stopped upon error" after 2 runs.

Even when I went back to stock settings ("optimized defaults" in BIOS), the same thing happens.

Specs and Linx settings below. Maybe someone knows why this would happen?

Specs:

What is your RAM stock voltage? What is the part number on the RAM? Con you go into your user CP and fill in your spec's?

dubesor

RAM is rated for 1.65V. On stock settings, it's at 1.5V. When OCing, I upped it to 1.64V.

Quantum Reality

I had similar issues with my RAM. It passed memtest86+ at DDR3-1633 8-8-8-24 but refused to reliably behave with Prime95 blend and some other tests.

Finally, backing it off to DDR3-1333 7-7-7-21 cured lingering issues.

Sometimes voltage just does not save ya.

Gonna run memtest now, see what happens ...

dubesor

Well, it's probably a RAM problem. I ran memtest twice - first with the settings on auto in BIOS (it read the timings as 7-7-7-19) and 2nd with its rated timings of 9-9-9-24. Both times, the test stops at 7% and sort of hangs there ...

So where do I go from here?

Quantum Reality

Did you make sure your motherboard is not overclocking the RAM? If it is you should:

1. Back it off to the appropriate speed.
2. Verify that it is providing the right voltage for those stock settings.

dubesor

I think if anything, the motherboard is underclocking the RAM. Memtest reports the speed as DDR3-1079 (539 MHz). Not sure what the right voltage is. I've run the RAM at 1.5, 1.6 and 1.64 now, but each setting produces Linx errors.

I think I've narrowed down these errors to a RAM module. I took the trouble to run each 2GB chip by itself through Memtest. One of them consistently produces the same error in Memtest test #6. I wonder if that means I have to return it to the store now. Yikes.

dubesor

Removed the offending module and now the other 2 pass Memtest fine in dual-channel mode. But Linx still "stopped upon error" after run #2. argh. what to do ...

Edit: 2nd try at Linx with 2 RAM chips fared better. Passed 14 runs - by far the best I've seen on this build yet, but still not good enough

Why don't you post the rest of your timings, maybe it's not the ram.
