Have you tried loading Opt defaults in the PWM screen then manually resetting your voltage!
This has been one of my major headaches until I discovered what it was doing. The DQ5 is worse at this as I had to clear CMOS to get it to play nice.

[Final8ty]

Did you try my settings on the First page?

Had another go with the Quad now & i did use your settings before but no go
until now & needed 1.55 to be stable under the S&M CPU only Loop All CPU Usage Maximum test + the new PSU.

Is there any advantage in using the cpu feature to over clock than using than Multi`s

I have been seeing people getting 2.8 3.0 3.4 from my supplier recently so i should have another Quad tomorrow & hope i get more luck than the one i have now.

Can someone tell me what AutoExpress is & where the settings are ?.

The Answer is YES use the Hexidecimal for CPU -NB the Multi HT does not fair even remotely as well as setting it through Hex! Just Leave HT Multi set to AUTO and DO NOT touch it!

[Final8ty]

The Answer is YES use the Hexadecimal for CPU -NB the Multi HT does not fair even remotely as well as setting it through Hex! Just Leave HT Multi set to AUTO and DO NOT touch it!

I did notice that the hex way was better but why ? & the people who are getting 3.4-3.5 using the multi may see even more using the HEX.
oh & im upto v1.58 now as i had a few BSOD if been sitting idle then put under pressure.
It has only got to survive until the morning

[DIE.SL]

Thanks!!... I´m going to try now...

It´s strange, When I OC with multiplier the system turns unstable but I dicreased the multiplier to 13 and I upped the FSB to 215 (previously I changed the HTT to 1800mhz) and now runs perfect at 2800 mhz)...

Anyone can Explain this?

Finally I still have the same problem,the system ·froze· in windows but in my opinion the system is more stable anyway increasing FSB...

In the other way one sensor (PWMIC) shows 63º isn´t quite high? Can be the power supply?

[Brother Esau]

Every bodies experience is different I have had not issue one God Bless, with this board or Phenom

[DIE.SL]

Thanks...I´m working on it...

anyway in our opinion what of those phenom´s the best looking the stepping:

HD985ZXAJ4BGH JAAFB AA 0812BPDW 9521504C80141
or

HD985ZXAJ4BGH JAAFB AA 0812BPMW 9521504C80133

[illogical]

That is not the stepping.
The stepping as displayed by CPUZ, of mine is 3, the revision is, DR-B3.
What you are referring to I think is the batch number as printed on the CPU, calling it stepping is just plain wrong and confusing.

[Final8ty]

New JAAFB AA 0812BPDW @2.8 stock Vcore
see if its stable.

[DIE.SL]

New JAAFB AA 0812BPDW @2.8 stock Vcore
see if its stable.

Finally I tried the 2 phenoms...the second is the best...HD985ZXAJ4BGH JAAFB AA 0812BPMW 9521504C80133

I still have problems to pass 2800mhz with anyones but thanks to PWMIC sensor I think the problem is the power supply..it haves problems with the ATX 12V voltage and turns inestable when hits high temperatures...(75º I think is too much...)

About the processors the best runs at 2,8 ghz at stock voltage when the PWMIC sensor don´t show a very high temperature (I´ll try a corsair 620W one of these days...xilence sucks)

Today I configured the phenom 201 x 13,5 at 1,23 and runs perfect at 2710 mhz and I think I can dicrease the voltage more... (1,20 sounds good)

[d4d4cH]

unfortunately dfi 790fx-m2r + 9850 phenom proved to be unstable crap for me...even on stock...never been more disappointed...replaced it with intel for now...gonna give it another go when amd actually releases chipset that will be 100% compatible with their cpus

Gone back to my 6400BE now until the new chipset comes out.

[DIE.SL]

Finally the problem is the power supply...
Now runs perfect with less voltage (1,23 at >2,8 ghz)

I think this CPU is good to OC...

[Final8ty]

Go For it! 3700Ghz is is the bar atm

[Final8ty]

I could not resist, the Quad is back in.
I hope the new chipset really is the answer as i have never seen such funny behaver from a cpu.

Did 14 hours 4core prime stable at 2.9 stock volts shut prime down fired up FireFox & then 5 mins later BSOD secondary CPU intur.
rebooted BSOD, rebooted then made it into windows 5 mins BSOD.
Dropped to 2.8 8 hours later while useing FireFox BSOD secondary CPU intur.

[coltsrock]

So when is the 790GX slated to come out??????

yeah there is definitely something wrong with the way motherboard "works" the CPU...hopefully new motherboards can fix it

[Rammsteiner]

There's a shop in The Netherlands having an ETA of 50 days for Foxconn A79A-S. So I think around that time, hopefully sooner though.

oooh so around late July Im building my rig at about that time

[OpticWaves]

I've got the DK and 9850. This is my very first rig to overclock.

In my overclocking I'm to the point where I just need to invest in water cooling. I'm able to get to 3.0 and pass a few minutes of prime95 blend but I hit 58C and get scared.

I think this is definitely overclockable even for a newb, I've just found that it has low ceilings with the FSB. With DDR2 about 236 and DDR2 1066 around 210 in my experience.

I don't know if some of you got lemons or what, but I love this gear.

I run the DK, 9850 and 2x2G OCZ Reaper HPC @ 1066.

Currently I'm at 14.5x200=2.9G passes prime blend for 15 min, will run longer tests soon.

Can you post detailed configuration of the bios to run at 14,5x200?

What about FID and DID in CPU features?

What is the best bios in your opinion to OC 9850BE?

Thanks...

[Brother Esau]

You need to stay lower with HT then that in most cases less stress on the CPU and board

[Final8ty]

Nice got 3Ghz out of the chip & it only took CPU/NB 1.65V to do it
idle temps 35oC

ooops! 1.7 now.
