Can't stabilize E8500 OC with DFI LP LT X48

You can use a USB stick or floppy. There is a windows based update utility, but as with all that kind of software, there's a fair element of risk.

To be safe, use the latest final release of BIOS.

Figures, I guess I'll wait until there is a new official BIOS then. I remember a post in one of your review threads saying one of the newer BIOSes were more stable or something.

That was for the DDR3 version, but you can find beta BIOSes for your board here.

Ah, I see. I'll still wait though for an official release BIOS. Wish we could flash in Windows, much more convenient for me. I'll have to gut one of the comps lying around my house for a floppy when I flash.

I found that messing with my NB voltage (lowering it) would provide stability. At 1.4v for the NB, Prime would error out in several minutes. With lower voltage (1.28v), my system would pass a few hours of Prime with no problem while the rest of the BIOS settings were the same. Is this normal?

I'm curious, would messing with GTL/REF/VTT voltage help with my Duo OCing with the same speeds at lower volts?

Thanks Clunk!

--Edit--

Great, now my system decides it doesn't want to be 5 minutes Prime stable with the same settings that were 4 hours Prime stable. Awesome.... Oh yea, it's always a rounding error. Says result was .5 expected less than .4. Does that mean anything?

You can flash in windows, use winflash 1.92 that's available on the BIOS site. In fact, I've used this twice recently with success because I didn't have a USB/floppy I could use.

Just be aware that there is an increased chance of things going belly up doing it this way.

Try some VTT.

VTT huh? I'll go check out the GTL/REF table in the X48 LT review for 1.200 VTT in the BIOS.

GTL/REF is .67% of the VTT voltage (real one) for all three GTL/REF voltage settings (1/2, 0/3,/ NB), right? I'm new to GTL/REF voltages.

Should be 63 ish for the CPU and 67 for NB, but try your GTL ref disabled and add some VTT.

Will do, but it's .63% for GTL/REF of 1/2 and 0/3, right (just want to be sure, sorry for all the questions)?

[Clunk]

Yes.

GTL Ref/VTT made it a little bit more stable (an hour).

I just flashed to the 7/25 BIOS. After flashing in Windows, the BIOS settings I originally had with my previous BIOS would not boot. I think it may have something to do with the new GTL/REF settings. After disabling GTL/REF settings in the BIOS, everything boots up fine. Disabling the GTL/REF settings were the only things I changed from my previous settings. I left the VTT at 1.2v.

Someone on OCN said this new BIOS let them drop voltages while still running the same clocks with full stability. Hope I get similar results.

Would running a higher FSB/with a lower multi allow me to run the same clocks with lower CPU voltage?
