Weird Dual-Channel Memory on Asus A8V Problems

[mike3411]

I have an Asus A8V, with an Athlon64 2000+ and two sticks of Corsair VS512MB400 . After noticing more instability than I'd expect, I decided to run Memtest to check the RAM. Using memtest86+ v1.70 from a CD I checked each stick of RAM separately, and after a few a hours of testing each, neither returned any errors.

However, when I put both sticks in, Memtest shows repeated errors on test #5. I have the sticks in the appropriate banks (DIMM_A1 and DIMM_B1) and the BIOS is set to defaults. This RAM is specifically listed as compatible in the A8V manual, and I don't think I've changed any jumper settings.

Anyone have a clue what the problem is? I'm tempted to RMA the memory, but since each passes memtest separately, I'm not so sure that is the problem.

Any help would be appreciated! I'm quite confused : /

Try bumping the VDIMM a little when testing both sticks.

Let us know if that clears the memtest errors.

Wow, that seems to have worked! I increased the VDIMM to 1.65, and Memtest no longer reports errors. Should I go ahead and use the system this way? It seems to have fixed the system stability, even though I wasn't entirely sure it was a memory issue in the first place (and I still get a beep or two, erratically, on cold boot). Is it worth RMA'ing the sticks or am I better off using the RAM since it seems to be working ok now?
Thanks!

I have two 512 sticks of Corsair 3200 LL and have run them with the voltage at 2.7 rather than the spec'd 2.6. That's on an A7N8X and now an A8V.
I get kicked from IL-2 if I don't.

keep the ram
