ocwbeta3 BIOS for Asrock 939

[dunkster]

I downloaded and flashed the ocwbeta3 BIOS this morning.

Bottom line: No discernable advantage or performance difference between this and the Asrock 1.20 BIOS. Nothing gained - nothing lost.
- With my system, still can't run stably with 1T at any memory clock speed over 133MHz.
- Same Sandra memory bandwidth at equal settings.
- Same SuperPi time-to-completion at equal settings.

Rock-stable at 11X250 with RAM at 250MHz 2.5/3/3/7 2T with neither Vcore nor Vdimm mod.

Immediate failure of Memtest86 Test#8 at any memory clock setting above 133MHz with 1T command rate.

Don't bother.

Thanks for the info dunkster. Some people have said they got 1t working with this bios but certainly not all of them.

I wish they would add a 150mhz ram divider option. A 183 I'm sure would be nice for some people as well.

You can manually set the divider to 150 in Windows. I do when I need the extra boost. I set it to 133mhz in bios. Then load up A64 Tweaker. It says that 150* is reserved but it DOES WORK. It is a funky divider though. It only gives me 12-13mhz or so more over the 133mhz option. The cpu sets up a wierd divider with the 150* setting but it does help some at least

Yeah, I've heard you can get it to work with A64 tweaker...which seems to indicate it could be made to work in the bios. I'd rather just be able to set it in bios and be done with it.
