Gigabyte MA790FX DQ6

[Brother Esau]

How is that chip doing?

The new chipo I got (0811) won't run at stock on the MA790FX-DS5. At stock BIOS (optimized) I can run some applications but it will reboot at awkward times. If I change the memory from the 1066 EPP to the 800 SPD it does not improve. (And using older DDR2-400 ram will allow it to work for longer but will still crash the Prime95.)

At stock with the 9850 it boots and will run Prime95 for 15-45 minutes.

With as many people that seem to have problems with the 9850 and the Gigabyte I'm betting it's a BIOS problem and not the CPU. If I underclock the CPU Core multiplier to 10 (So 2.0Ghz) then Prime95 will run for 4 hours or so.

I think (as you have posted) that the NB is clocked incorrectly at stock for the 9850 on the DS5 motherboard. However increasing the NV VID by setting the BIOS to the -0.05 value makes the system even more unstable... so perhaps there is more than one setting that needs to change for the 9580 to be stable? We need to change: NB VID and also <Insert something else here>

Gigabyte will probably have a new BIOS that will fix things eventually; but of course we need it NOW.

But in the meantime I'm just considering ordering a new DFI 790FX-M2R now that newegg has them in stock again. I'll just throw this board over into my "stuff that doesn't get used but is not really trash but is almost trash so I don't know if I really want to use it" pile of stuff.

Do it Keith!

Do it Keith!

I'm tempted.

Besides... Murphy's law of system building says if I spend the money to get a new DFI because of the piddling problems with the Gigabyte then they will release a new BIOS while the DFI is in being delivered. (So it would be good for others.... I'm so altruistic.)

Luckily I have to go on a 2 week trip starting monday... so I won't be able to do anything for 3 weeks. By then we'll see if the bios is out. If not... who knows. But this "forces" me to be a bit more patient.

(But I know this memory works well on the DFI... and I really miss the power/reset button BIOS reset method.)
