Failing Memtest

Hi

I have recently purchased the Gigabyte GA-EP45T-UD3LR motherboard with latest bios of F7- http://www.gigabyte.com.tw/Products/Motherboard/Product...

and 2 x 2Gb of OCZ DDR3 1333 Gold -
http://www.ocztechnology.com/products/memory/ocz_ddr3_p...

When i installed the new mobo and ram it installed ok. I then ran memtest to check that the ram was working ok. When the test starts it only gets to 48% of the 1st test and then restarts the PC. If i take 1 stick of ram out and re run memtest, the test runs flawlessly. I then tried the other stick on its own and it passes the test no problems. I have ran Windows 7 Memory Diagnostic test with both sticks installed without any errors. I have also ran the Blend test on Prime 95 for 2 hours without any errors.

I'm confused. Memtest isn't liking the 2 sticks installed, but both windows and prime 95 haven't got a problem. Should I take no notice of Memtest or is there issues with my Ram settings?

I have the ram set at the following:

C.I.A.2 to {Disabled}
Performance Enhance to {Standard}
DRAM Timing Selectable to {Manual}
Memory Timings to CL 9-9-9-20 (CL-TRCD-TRP-TRAS)
Command Rate to {2}
tRFC to {88}

MCH Core to {1.35 volts}
DRAM Voltage to {1.7 volts}

The rest of my system is as follows:

Cpu - Q6600 2.4Ghz overclocked to 3.2Ghz
Gfx - XFX GTX 280
HDD - WD 300GB Velociraptor
Corsair H50 Heatsink
PSU - 600W OCZ

Many Thanks

Raise the RAM voltage to 1.75V. If you are using the green RAM slots - switch to the pink slots and run memtest86+ again. Since you are OCing your CPU, you may also be OCing your RAM (unless you adjusted the RAM divider to keep it at or below 1366MHz), if so, you may have to increase the FSB voltage a little (1 or 2 bumps above the default).
