Asus M3A78-T + 9950BE overclocking... wow its all new again

[QuietIce]

Very nice, but now I get to throw all instabilty testing Ive done out the window. Vista auto updates at 3am everyday so my overnight orthos may have been stable after all. I caught it today doing a countdown to restart. It had killed one process of orthos, the others was 11hr stable and running. grrrr

Basic tenet of OC'ing: Always turn off the automatics.


And when it comes to Windows that's the first order of business even if I'm not experimenting ...

Im not used to being able to update windows.... first time in years lol. I need to vLite Vista one of these days.

Anyone have any idea what the option CPU Tweak does? Defaults enabled...


Also I didnt notice and automatic overclock when putting my phenom into a SB750 board like AMD claimed. My 9950BE defaulted to 2.6ghz rather than 2.8ghz.

Erm it isn't "automatic".

I think Tweak is the adjustment for the TLB bug on B2 chips.


IIRC the 9950 IS a 2.6 GHz chip. And I think MrMojoZ is right - I don't remember anyone saying anything about an "automatic overclock". Linky please ...?

hey gotVoltage, what is your vdimm? i noticed you got trc = 26 which seems really low, i have to have mine ~40 if i wanna keep vdimm low (when running ram @ or near 1066)

@2.2v to 1120mhz and @2.3v to 1175mhz.. ther revision 1.2 Dominators..one of the last with microns by Corsair.

CPU Tweak changes how the caches are managed
It increases individual core performance but there is minor lost in multi-threading

Cinebench10 is best way to see the difference

I enable CPU Tweak all the time now

Im looking for the link, but the way I understood it was that the Sb750 would increase any phenom by 200mhz by default, so a 2.6 would boot at 2.8. maybe I misinterpreted it

[QuietIce]

Ya - I've never seen anything like that anywhere. And if you find it I wouldn't trust the site it's from ever again.

But a lot of people were saying that 200 MHz is the average increase in OC for the 9850 and older chips using an SB750 board ...

It was first being said in some sort of way that with ACC and a SB750 you'd gain a 400Mhz boost with a Phenom BE (I think it was BE only?) and 200Mhz with a SB700.

However, I dont think this was automatically and actually recquired some input. Also Im unsure whether that SB700 statement was true after all since it does not feature the same fixes as the SB750 had.

Maybe it was a bit based on that with a SB750 a Phenom BE can simply OC 400Mhz at least and with a SB700 only 200Mhz, I dont know really. But first it was put in a complete different day light than before. However, after all SB750 does its job, but it's not automatically. Or maybe you got to leave everything on auto in the BIOS? Including MP's/HTT/V's and ACC? Is that resulting in a standard 400Mhz+?

[Jimmer411]

I dunno, everything auto was 2.6ghz. But who uses auto these days?


I finally got burnt by vista Ive got some problem where it cant connect to the group policy holder service so anything I open fails just about. failed to load driver. Happens at 100% stock and overclocked.

Also anyone know how the oc profile tool working on this board?

Thats just a registry corruption issue.... just do a repair install with the Vista Install DVD, and this should fix the registry for you....

[Jimmer411]

I did a clean install of vista again. For some reason my XP and my Asus drivers just wouldnt get along.

[QuietIce]

I hope they get along with Win2K ...

[Jimmer411]

win2k?


Pretty much every driver would do the quick command prompt window close fast when opened. Those were the updated drivers off the asus site.


Forgot to pull disk out of other dvd drive while I had it setup out of case and too lazy to find a paper clip...lool

Can any one help? I keep getting blue screen of death with this board Asus M3A78-T. My ram, harddrives and CPU worked with out any problems on the Asus M2n32-SLI Delux. I was getting blue screen of death evey hour until I turned off the onboard video & put my old video card back in. Memtest did not find any problems with my ram. I was still getting the odd BSOD until I uped my ram voltage from 1.9 volts to 2.0 volts. Is there any other votages I should set that should make this board a bit more stable? Many thanks for any help.

Check for Bios updates pertaining to the Onboard Graphics..

The Bluescreen i believe is Bios Driver Related for the Onboard Graphics...Biostar had simalar issue with GX/GX2/GX3.. But new Bios release fixed it.. Also ACC will be very buggy sometimes..Dont use it if you can Oc good with out it..

Im shure the ACC funtion will be better with Bios updates as well...
Ive been trouble shooting my friends set up and all his problems go away when he disables the onboard graphics and ACC. ASUS 78-T..Im also looking at the 79-T for myself

P.S. i still have my M2N32deluxe with 1903bios too..Great Mobo for X2's/X4's with the 1903..although HT/Nb is limited.

[nuts24]

Thanks for the help gOtVoltage,

But I had the on board video and ACC turned off and was not using AOD, had the CPU running at stock & my system still crashed, I took out the montherboard on Sat and sent it back, put my old Asus M2N32-sli back in & I have not had one problem all weekend. I must of tried every driver and Bios that was out for the M3A78-T and just could not get it to work for any logger than a few hours.

Does any one know out of the gigabyte 790GX and the Biostart 790GX board which one would be the better buy?

Many thanks for any help on this.

[Jimmer411]

I find my system is most stable with ACC set on auto. Also have you tried the 667 ram speed vs 800?
