The Phenom II List of Overclocks

[batmang]

I'm anxious to see how much people using a K9A2 with a 920 will get. My 920 arrives tomorrow. I'm hoping for 3.5 with this board.

I posted this in a couple of other forums but for those of you who do not visit those I have some good news and some bad news.

The bad news is I no longer have the (ES) chip as I sold it off to someone else so I could get a Retail chip to see if it was pretty much the same. Why do I say that is bad news............well.....it was not a Phenom II 940 BE (ES) AM2+ chip......it was a Phenom II 945 BE (ES) AM3 chip. I just confirmed it today when I took a look at the pins on the AM2+ version and they are different. There are other things that have caused a suspicion as well, but this actually sealed the deal.

Anyway some one is going to have some fun if they can get them an AM3 MB and some good DDR3.

I would have given them the retail chip and kept the ES....Or even sold it on E-pay

You'll need to use WPCREDIT to reduce the NB multi, but then with decent temps 4ghz is entirely possible.

[Macadamia]

But BenBrown your chip didn't run at 1.25V on stock voltage right?


I thought AM3 CPUs were supposed to have that instead... or maybe it's just constrained to the 945.

bios wasnt detecting it as AM3 because he would have noticed right away.

Nope it was running @ 1.35, same as the retail 940's.

Actually with the new beta bios, there is a bug where the HT multi actually is the NB multiplier. I raised my northbridge, so lowering it shouldn't be a problem. It's bios 1.7b4.

Getting my 920 (Which i just happent to win lol) tomorrow aswell for my K9A2 Platinum.

I am expecting a 260 x 14 = 3640mhz or 280 x 13 = 3640 stable, depending on how my RAM likes it as they top around 1140mhz. Already got Beta BIOS so iam good to go

[Lightman]

Hello again!

I finally managed to get my Windows x32 install to a SSD drive! Experiment went successful and this is what I was able to come up with:

Close to max. AIR clock:
4200MHz@1.58V

Above run settings: NB 11x; HTT 200MHz; AIR TT 120 Ultra + 12cm FAN 1200RPM

This is fairly stable (1h benching and playing around), I will try to prime it tomorrow.

[oc_junkY]

first of all, great results you all got there with those pii's.

i'm at a point where the CPU test from occt runs fine for an hour.
the ram and mix crash after a while, BUT:
if i lower the multi of the cpu and just the it,nothing else, ram and mix mode run fine too?!
raising the vcore doesn't give a better result. i just don't get it.

can anyone using the m3a79-t deluxe post his complete bios settings from htt to sbvolts?

[fizur2002]

Lightman is that board you are using the same as my M3A78-T board?

[HondaGuy]

Nice OC Lightman: 0848FPAW here

Are you referring to the HT ratio? This doesn't change the NB multplier, just the HT ratio.
This is the only thing holding me back right now. My ram does 1080mhz+. I NEED to be able to lower the damn NB multi!!! STUPID K9A2!

[soundood]

i got to admit, it is allways something i missed in this board im using (AX78) the annoying thing is that it states that the nb multi is there in the manual,

must have made the manual before the bios, as its not

cant wait to get the crosshair II, WHERE ARE YOU? DAMN POSTAGE

[Lightman]

For Phenom II I'm using MA790FX-DQ6 based around SB600.
ASUS is in my HTPC

Nice OC Lightman: 0848FPAW here

Thanks!

Nice OC as well
Is it Pi 1M stable or just CPU-Z??

BTW my OC for 4.2GHz was on all four cores.

I'm saying that in the beta bios, the HT Multiplier is mis-labeled. I raised the ht multiplier, and instead of it raising the HT Ratio, it raised the northbridge.

I had the crosshair II, and when it went bad after a bad flash, i went to the shop i got it and took something else instead.
It has so many features and flashy things but it is nothing special. At least with phenom I.

[oc_junkY]

sorry for beeing new to amd/phenom oc'ing and asking such questions ;-) i came right from intel p965/core2 to my first amd platform.
i have found out that raising the vcore will bring stability for high northbridge clocks (>2700mhz),
while i can change the processor-nb volts from 1.35 to 1.5 without any influence on the nb stability.
is there something wrong with my board or cpu or is it the same for you?

[fizur2002]

well i cant seem to figure out what my voltages and settings need to be on this board to get my 940 stable. Here is some screen shots of my bios and hopefully you guys can help me get this under control. Ive only been overclocking intel CPUs for the past 2 years and coming back to AMD makes me feel noobish again.

I think your processor-nb volt is too low.
how stable are those settings? do they post?

[Smartidiot89]

Got my CPU now: 0841GPMW

Time to install it with my new Cooler Master V8 and have some fun

[TL1000S]

@Fizur2002:
You must check/set your DRAM-speed to manual to verify the current "divider".
At present you have no control over the resulting DRAM-speed vs HTT(FSB).
Since you've got a 940 I see no point in "fiddling" with HTT(FSB).
Just let everything exept VCore/MP be "Auto" to find the OC-potential for your "chip".

[batmang]

This is the 1.7b4 BIOS your referring to?

Is that a retail chip? week 41?

yeah, looking at his sig, mem is running ~920mhz with Auto setting. Thats probably the wall.

BTW, fizur2002, I think you don't need those high HT and PCI-e voltages.
