He's Alive Why a week I said a day would help see if there is issues at defaults.

Any way You must have a duff board man my first one was a bummer also get a RMA

Have to use the PC for business things last week, there wasn't much room for OC.

Will wait for the next BIOS releases and see if this is a common problem of the board/BIOS in combination with the Phenom or if only some users are affected.

Next step is to contact the DFI support... EDIT: done

Congrats!

Do you have any idea how can I enable the AHCI mode on this board? I see just Legacy, Native and Raid modes in the BIOS. I set the Native mode, but I can't see the hotswap option on the taskbar.

MOD: What is the difference between the CPU Host/HTT Clock and the CPU Host/HTT Boot Up Clock? ...and what is the CPU Host/HTT Adjust Gap?

its a start

Added some more content and updated Front Page with Prime 95 Runs with BIios Template settings

keep on trucking looks like this board is it for me will order it on my next paycheck... just gotta patiently wait

New 12/21/07 Beta Bios Rocks By far from what I see and feel its the best Bios to date!

[speedlimiter]

Ordered a GP-9600BE today to avoid the boot problem. Don't want to wait until DFI is able to solve it. Also my HD3870 needs a powerful CPU to get a decent performance boost. The differences @ 2,2GHz are only 500 points in 3DM06 compared to a single card. If i make the computer to get past the blank screen () @ 2,6-2,8GHz the difference in 3DMark ist much bigger (2000-3000 points).

For all other Phenom+DFI users: the boot problem is reported to DFI.

What sort of boot problem? I don't have any boot problem.

Do you have a Phenom? OC? This problems start @ around 205MHz HTT.

just a warning for ya, i wouldn't recommend using your OC computer as a business computer.... I just hate the hassle of things when something doesn't work right the first time, but that could just be me. my laptop I use for my car tuning

"New" Beta Bios For D.F.I LanParty UT 790FX-M2R ...Linky....12/21/07 Beta.....Linky........DrDOS

Please Do this..... Do Proper Clear Cmos DO NOT REMOVE BATTERY Boot into Pure DOS with DR DOS using only PS2 Keyboard when you get to A:\ prompt insert 12/21/07 Bios .EXE Floppy ..Type at ....A:\ Prompt

A:\AWDFLASH.EXE R7LDC21.BIN /CD /CP /CC /PY /CKS /SN /F /QI /LD /WB /E ....after its done Flashing the /E switch will take you back to A:\ Prompt at that time repeat .........A:\AWDFLASH.EXE R7LDC21.BIN /CD /CP /CC /PY /CKS /SN /F /QI /LD /WB /E

Remove Floppy Power Down computer manually allow clear cmos for 10 minutes load optimed defaults /save/exit go back into Bios set up Date accordingly and leave at Optimized defaults for about a hour....Please.

EDIT: ...Proper Spacing between switching Parameters is CRITICAL

So far I like this Bios but remember you do this at you're own risk!

Bro, i think the link should be this.

[Brother Esau]

why is that I don't get it OK...thats odd...I checked the Bios Link and it was 12/06/07????/ I confirmed it was proper when I posted it!

[Nedjo]

The New BIOS has TLB Cache-something option under Memory settings! End if you want "full" scores it must be "Enabled"! AOD just doesn't help if this option is Disabled.

[Brother Esau]

@Nejdo ....do you have a Phenom? If so what are you're available options under HT Link Control????

I'll make picture and will post it today...

[speedlimiter]

+ another user @ forumdeluxx.de who experienced the start problems. He has a 9600BE and his boot problems begin @ 203HTT.

Please DFI - Phenom users really neeeed a new BIOS.

My 9600BE should arrive today, so i have the possibility to OC by changing the multi.

EDIT: 9600BE is here, will put it in as soon as i get home.

We waiting for your results

+ one user with boot problems @ 203HTT (9600 nonBE)

Don't think by now that my board is a bad one, it's a general problem of the board in combination with the Phenom.

Hurry DFI

Yea my board also does that, running 220*11 know, wating for my 9600 BE, from a slow ass webshop there in SWE

[speedlimiter]

So,

what should i say: This board is total crap with my 9600BE.

- Plugged in the 9600BE
- CMOS Reset
- Turned computer on, BIOS -> Load Optimized Defaults
- Turned off CnQ and Virtualization
- booted Windows
- AMD OverDrive (the new beta) -> increased vcore to 1,4V and multi to 12,5 = 2500MHz = no problem
- set multi to 13 = freeze
- made the same in the BIOS (13x200, 1,4V) -> freeze @ windows boot
- upped all the voltages in the PWM section ~ +0,2V, DDR2-400, CL5-5-5-18, nb-multi 8x, ht-link to 800MHz -> no boot screen

This board is definitively NOT "Phenom ready".

I can't believe the BE is so bad, my 9500 could reach 2750MHz but with the mentioned boot problems.

EDIT: 9600BE -> the 2500MHz are NOT Prime-stable

Waiting for your next BIOS Mr. and Mrs. DFI

EDIT2: And again i'm not the only one. Similar results @ another DFI user 9600BE @ 2,6 max. no matter what vcore

[speedlimiter]

Same with HHT-Overclocking:

nb-multi 7x, HTLink 600MHz, VCore 1,4V max: 11,5x220=2530MHz

The same as with multi-OC, so i think this is the limit of the cpu.

Have to think about getting a new one.

The only good thing: The boot problems with HTT > 205MHz are gone with the 9600BE.

[Lightman]

WOW That sucks!

I've read at least 2 other 9600BE could reach only 2.5GHz....

Looks like this will be a lottery of OC for us...

Can we start stepping database of 9600BE to help people buy better product?

What are your and your friend steppings and production weeks?

Thanks for info .

[afireinside]

Not even 2.5 ouch... I hope they aren't that bad when they show up state side. Any day now...

[MR.Q]

This is extremely bad news. I am deeply saddened by these events and am finding it hard to keep a positive attitude.

Where is MACCY? Where has he dissapeared to?

I think we users need to make some sort of announcement regarding future purchases of ANY cpu's from AMD. I'd be one of the first users to defend AMD in many cases but this is simply becoming too much to take.

I (and many of you) have waited over a year for these cpu's to see the light of day and tbh I think they need to go back under wraps until they actually work properly.

I've dealt with allsorts of problems concerning this 9500 B2 and simply cannot face more and more let-downs from the green giant. I mean they've been working on this architecture for nearly three years, wth is going on.

I'm gonna give it one more week, and if there is no light at the end of the tunnel then I'll switch over to INTEL completely. I literally love AMD cpu's but I refuse to keep ploughing £££££££ into crap that doesn't work.

This morning alone I must've encountered the TLB errata bug first hand atleast 8 times. AMD insist on requiring an intricate set of circumstances and a LABORATORY being required to re-create the TLB errata. Personally I belive that to be false as all the lockups my system encounters cannot be attributed to anything else. I've tried several times this morning to oc to it's 2800mhz '06 benchable speed but keep getting lock-ups around the 2530mhz to 2680mhz range. On the ninth attempt I managed to get 27++mhz before lockup, and this is with no settings changed. It really is a lottery with these cpu's atm.

When they work correctly without failure at a decent clockspeed they appear very good. However the rest of the time (during massive problems and having to remain close to stock speed) I'd rather have my old 6000+.

I'd really like to see some AMD flesh in here explaining wth is going on.

[JWilson]

I am so dissappointed with AMD. I have Bartons running that can OC better then this Phenom! With the release of the Black Edition Brisbanes, I thought the Phenom would kick-ass for sure. I'm so dissappointed
