memtest error - reasonable fix?

[NimRock]

Hey.

Putting together my new rig and I got a pair of errors on memtest at the test bench stage. Ran memtest overnight and there were two more errors in the morning.

I don't fully understand memtest but it got the impression it might be the slots. Moved the ram from 1 and 2 to slots 3 and 4 and 12 hours of memtest show no errors.

Am I right in the conclusion it's the mobo? Any chance its the cpu? It was running pretty hot at first as the stock cooler wasn't making good contact. But the first thing I did was prime 95 noticed it was heading over 90 and stopped and fixed it. Temps are below 70 on prime 95 now

I'm probably happy to be limited to two ram sticks to avoid trying to remove the cpu to RMA the mobo. If the mobo slots are really the issue.

The only other ram I have about is old ddr 2 stuff so I don't know if I can use that to test the slots.

Bit stressed so any help is much appreciated.

Full rig specs? 

 

Might have been the temps, but if you swapped the slots and it worked fine then I guess it could be the motherboard.

 

Try it in those slots for 24 hour and see if any error comes up

I dont really think that it is your motherboard it its basically just wires. Looks like the memory controller of your cpu is the problem, they are less stable when the cpu is overclocked and hot. I could imagine that running hot for a longer time could have caused the problem.

Full specs are 4670. Not overclocked

2 x 4 gig corsair vengeance pro at spd speed of 1333

Gtx 770

Gigabyte b85m d3h mobo.

Vertex 3 ssd

Tx 650 psu

The steps I took were install win 8 to the ssd and launch cpuid and temps were in the 70s. Jumped to 90s when I started prime 95. Shutdown, push the stock cooler down harder, reboot a and temps are fine.

Then a few hours of prime 95 and on too memtest.

From the mobo manual:

 

"When enabling Dual Channel mode with two or four memory modules, it is recommended that memory 

of the same capacity, brand, speed, and chips be used. For optimum performance, when enabling 

Dual Channel mode with two memory modules, we recommend that you install them in the DDR3_1 

and DDR3_2 sockets."

Memtest just errored on the other slots too. No choice but to replace the ram now I guess. Which sux because it's the one key part I didn't by locally. So I either buy more locally at twice the price (and end up with spares) or wait almost a month for the RMA.
