Hi,

Last saturday I bought 2 kit F2-8500CL5D-4GBPK for my Gigabyte EP35-DS4.

what is the problem: Lots of blue screen crashes at least once every 3 hours of computer usage.

Test protocol: TestMem86+ v2.11, 60 minutes per kit and per slot.

2 x 2Go => no freeze, no errors
4 x 2Go 800MHz 1.8v => errors ans freeze (random)
4 x 2Go 1066MHz 2.1v => errors ans freeze (random)

Thanks, Sorry my english...

What is your tRFC? Running 4x2 generally takes a higher tRFC than what Gigabyte 'figures', might try about 82. Also what's your NB and vCore settings?

Your BIOS screen shot shows the CPU frequency at 266, you want 333, give that a try and I'll grab a closer look when I get back - be gone an 60-90 minutes or so.

May be in the BIOS, latest (F7) can be found here:

It should have RAM updates included to match up better to the more current SPDs being run, I know it shows the update as the primary being Xpress BIOS Rescue, but there are always a lot more included

Motherboard is a GA-EP35-DS4 (rev.2.1) and not a GA-P35T-DQ6 (rev. 1.0).
