Memtest Failure. Help?

Hey guys!

I've been getting computer freezes and random restarts at time(s) with my current computer.

• I have not overclocked the computer.

• Had 2 different GPUs (after an RMA) Problem occurs both times

• Had a Full Modular Rosewill PSU. Changed to Corsair and problems still persist

Here are the specs:

NZXT M59 Case (1 Front Fan, 1 Top Fan, 1 Side Fan, 1 Rear Fan)
Intel i5-760
Windows Home 7
GTX 470 Video Card
Seagate Barracuda 1.5 TB Hard Drive
Corsair TX650 Watt Power Supply (Old)

MSi P55A Fuzion Mobo DDR3 1066/1333/1600 (OC)/2000 (OC)/2133 (OC)

OCZ Flex II Memory (2x2) DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227567



Anyhow, I ran Memtest for each individual memory to see if that could have been the problem. Here is what the tests have shown:

1) Test OCZ Stick #1 by itself. Timings set to 8-8-8-24, 1333 and 1.65 Voltage.
8 Passes. 0 Errors.

2) Test OCZ Stick #2 by itself. Timings set to 9-9-9-21, 1333 and 1.65 voltage.
9 Passes. 0 Errors.

3) Test OCZ Sticks #1 and #2 together. Timings are 8-8-8-20, 1333 and 1.65 voltage. 3 Errors:





Can anybody help me with any idea of what the problem could be here? Any ideas would help greatly!

• I'll run Prime95 if needed

• OCZ got out of the memory business so I can RMA these anytime

Neither link works.

What do your memory sticks say on the stickers for timings? Are these a matched pair? Why different timings for the single stick tests?

Links must've expired lol

The sticks are a matched pair that came together. On the sticks it sais "8-8-8 @1.65v"

I used different timings to try things out lol. Very confused right now

Are these your RAMS? Does the OCZ site have them listed with their timings?

If so, your sticks are timed at 8-8-8-24. Try that.

Have you set your voltage and timings in your BIOS manually and not on "auto?"

Yeah those are the sticks. I had changed a few of the settings:
Without changes my BIOS has them "auto" set at:
9-9-9-21/20 (Weird) @ 1.5v

Manually Changed them to:
8-8-8-24 @ 1.65v

Could it possibly be a dirty slot?

With the modules installed to either the blue or black slots, the timings set to 8-8-8-24 and DRAM voltage at 1.65-1.66V, make sure 1T/2T Memory Timing is set to 2T on both channels, and B2B CAS Delay is set to 0 on both channels. You may also need to bump VTT from the default of 1.10V to ~1.15-1.20.

Did all of that except changing the VTT part. I ran Memtest again with both sticks in and it went through 5 passes. Will run it for more passes in the next few days!

EDIT: WOW. Changed timings to 8-8-8-24 @ 1.65v and set both to 2T. It had 11 passes 0 errors.

The links above are malformed. Not even spelled out right.
