Me too!

Did anyone save the New bios? DFI´s download link is broken for me

[Oliverda]

Last night I switched to my Agena quad, and guess what? My dfi board does not have any NB speed "wall" like my Gigabyte... however it does hava a HTT wall around 225mhz so far... Have not tryd the new bios yet, using shipping bios 11/27 2007 know.

PWM runs hotter with my Quad around 65C after 8h+ of prime, 50-55C with my 6400+ Nb around 60-62C with both. Thats all for know, need to test if new bios has HTT wall....

I didn't get my board unfortunately, maybe on monday. How can the DFI adjust the NB multiplier upwards? Is it possible?

@Oliverda

to the forums, in case no one else did it

AFAIK NB multi is open

[speedlimiter]

BE CAREFUL! The new BIOS contains the TLB-fix.

Performance is more than worse:




There is actually no option to turn off the fix. I hope DFI will have it in future releases.

Does the new bios contain better support for AMD Overdrive?

Does the new bios contain better support for AMD Overdrive?

I got my board yesterday. I haven't done any testing with AOD. Should i test a special setting in AOD?

EDIT: Found the errata option. It's not in the CPU features etc. You have to go into the memory timings. There is a new option "apply errata 298 workaround". Disable it!

Memory bandwidth and access time are back to normal.

I have gotten a second board as the first had issues but this is me B-Day board so its rocking the house down compared to the first

I have not tried AMD Overdrive on this New Board yet but the first one had issues on 11/22/07 Bios with AMD Overdrive locking up just by opening it up!

Even with AMD Overdrive 2.10

No problems here with AOD 2.10 and BIOS 2007/11/22 or 2007/12/11. Changed some memory timings, ht-link multi, htt frequency - no lockups.

[Brother Esau]

I only used that Bios for one day but it was also used in Flakey board too!
How is this Bios compared to 11/22/07 ??? I know its kind of soon to tell probably for you but any comments are welcomed

[BadNizze]

Can´t find the new bios anyware! I dont supose anyone saved it? PM me if you did...

[ZL1Killa]

keep the results coming in yall!!!!!

If you want I have the EXE. 12/11/07 right here I can email it to you

BadNizze: Your 2k6 CPU score is ~40 points lower than what mine at the same HT ref./multi/CPU MHz but 1760MHz HT/NB and higher RAM timings gave.

Check your EVEREST latency. IT should be very low if your NB is that high.

speedlimiter: That really does suck. The way it looks to me is that the BIOS fix tries to disable the L3 cache. AMD's CPU is very L3 cache dependent.

I have not tried AMD Overdrive on this New Board yet but the first one had issues on 11/22/07 Bios with AMD Overdrive locking up just by opening it up!

If you're on XP, then go into C:\Program Files\AMD\AMD OverDrive\Logs\AOD\, search for the latest log by time/date which is in sync with the AOD crash and open it up to look for this:

Failed to initialize device AMD RD790 Clock Generator

Do you see that anywhere?
If you do, this is what causes the lockups on all the machines I've seen so far. It is also what tells you the "fake" HT/CPU low limit whilst it is only when AOD crashes.

[Brother Esau]

This program ever going t be like UGuru where it detects what ever the Bios is set to rather than the usual Defaults AMD Overdrive Detects no matter what the setting?

[KTE]

It detects most accurately like the BIOS values for the Gigabyte and MSI board users, better than other software.
Sami had said this week we should've had the new one release which is better and has core temperature monitoring. That really would be good but the week is over and no release yet. This older one is just too buggy yet. I'm always scared to even touch it and much worse when you oc, because it gives random lockups.

Hi there all, i am new to the community but have been following all your postings for a while as i got myself a DFI Lanparty 790FX, Muskkin 2 x 1gig 1066 ,HD3870 CF and a Phenom 9500. I am very new to overclocking and did get my CPU to 2530 but can't go higher. Running Vista x32 but busy installing X64 and SP1. I also could not run AOD as it froze. Overclocking from BIOS. I am also having problems booting windows with CF and only after a few resets will it start. My question is if the new bios corrects this and also the CF problems . Any other suggestions are welcome as i am a "noob" to overclocking.

[Brother Esau]

What Bios are you on? The new 12/11/07 has the Errata 298 work around in place and its enabled by default in bios under Memory options

[Swanie]

I am using R7LBD07 dated 07/11/07. Great review of this board Brother Esau.

[Brother Esau]

That Bios SUCKS Update: Immediately!

[Swanie]

Will do that now. Any suggestions on overclock settings will be appreciated. You stand by the DFI as the best 790FX ?

[Swanie]

Installed new Bios but still getting the odd "Not Booting" issues. How do you guys get to the speed of your Cpu's?.

[Lightman]

DFI is showing how BIOS support should look like !

BIOS with Errata for Phenom and an option to DISABLE it

Gigabyte need to take few lessons from fellow guys at DFI !
