Memtest Test 6

[DarthVR6]

Having a little problem. Specs are as follows:

DFI NF4 SLI-DR
AMD64 x2 3800
2gb [1gb x 2] OCZ Platinum EL @ 3-3-3-5 3.0v 1T.
BFG 7800GTX OC
Enermax 535w PSU
WD Caviar 160GB
WD Caviar 120GB
SB Audigy 2 Platinum
Windows XP w/ SP2

Currently I have the FSB at 250, HTT Multi at 3x. Ram is set to 1:1, timings are mentioned above. I can run Prime for 8hours+, SuperPi with no errors or problems. However, when it comes to Memtest, after about 4 hours of testing it'll fail test #6. It passes everything else [test #5 was looped for 25x with no errors]. Kinda stumped if I should consider this OC stable or not. I've played BF2 for hours with no hiccups. No Window errors.
Btw, I've tried 3-3-3-8 @ 3.1v, same problem. Any opinions/suggestions would be much appreciated.

BTW - CPU Voltage is at 1.4, any of you think I should up this or this could be the memtest error?

Anyone? Any opinions?

I'm on a very similar setup (see sig). I would try lower the ram multi to 9/10 and see if that helps. For reference I'm running my X2 3800+ at 1.525 volts on air (zalman 7700alcu). I'm prime stable and memtest stable both 24 hours and temps are 30/50. but my ram is at 217mhz. Anything higher than that, or tighter timings, causes memtest errors.
