post 83 and onwards will sort you out :thumbup:

after altering the NB multi in WPCREDIT, you must reboot pc for NB change to take effect. You must not enter the bios on reboot as this will remove the change wpcredit made and your bios will reinstate original NB multi. The NB multi change will then remain in effect until the next time you reboot your pc or shutdown.

Hope this helps guys.

So who wants some 3ghz HT Link loving?:D

Yeah... Its rock stable. The last restart was me doing updates but it had been going for at least a day or so before that. The only difference I noticed was an extra 2.5k in AM3, taking me up to 158k range. I'm going to go and try to see how far I can go with everything 1:1. Probably not far, but I can hope can't I?

NB voltage? :D

1.525 currently. CPU is at 1.6. Ram is 2.2. No other voltage has been touched.

Is this on the Vapo?

looks like some super vapo action to me!

good going oldguy!

man now im wondering if should pump 1.4'ish to get 2.8GHZ NB and couple it with 2.8GHZ HT. dont feel too comfy bout that much juice on the IMC tho. but, i can be persuaded! :)

Getting the M2R out again, replace the cooling with Thermalright HR09 MOSFET cooler, 2x Thermalright HR05 IFX coolers for the NB and SB (this time I wont try to use the stupid push pins, I feel very worried about the current HR05 on the SB, it's not all that tight:rolleyes:).

EK Supreme Acetal block on the CPU and 2 EK-VGA Supreme Acetal blocks on the HD4870X2 (seems like Ill have to mod the stock HD4870X2 heat sink, but Im going to keep that on though for the RAM and MOSFETs). Ive to get a new case though, prolly going to get a Silverstone TJ07. 360mm and 120mm rads in it should do the job:cool: And of course 1/2" tubes, going to be my first watercooling setup though:p:

Lets see where this beasty CPU will land:rolleyes: I'd love to get an AM3 board though but to be honest that would be a waste of money for a while. Since this chip already does 3.7Ghz on 1.48~1.49V on air, 4Ghz+ on water is certainly doable. I guess 99% of all PhII's could hit 4.5~5Ghz easy on subzero, so scaling isnt an issue. But well, on water Ill push Vcore real hard, although it's very likely my older 790FXB was just a lemon, I dont feel safe with 4+1 PWM lay-out, 790FX-M2R lay-out is a whole lot more trustworthy.

---

u will like water. maintenance/setup can be a pain though. my setup is whisper quiet for the most part. i should add another rad though with a low power fan to squeeze out another possible ~100-200, but eh this will do for now (this is insanely fast; basically a dream come true, and on AMD to boot!). i debated on getting higher power fans on the existing rads i have now, but i really enjoy the silence. coming from a single rad with a delta (last setup on s939), i never knew how much i enjoyed the quiet, till now!

as for the board, seems to be smoother for me then the 790fx-m2r i had. i see now that they are trying to sort the issues with it though...

I haven't let my phenom II run on anything but the vapo yet. For my quick 1-1-1 test I only got to 3.4ghz because I was htt limited since the ht link can only use multis up to 13x, at least on my board. I wish it was the modded vapo cause then I would be able to push my chip a little farther.

Expecting to add 300MHz to your overclock when going from air to water is way too optimistic, sorry to rain on your parade.

Just ain't gonna happen unless you're gonna use chilled water.

Yes, 4.0Ghz would be nice and everything I have read indicates that you should be able to get that with some water.

Actually I'm now looking at the double wide cases from Danger Den... then I could put in both a 4x120 AND a 3x120 radiators. (I'd like to get 4.0Ghz for a 24/7 overclock... but I also like complete silence.)

Got 3dmark stable @ 4.32, quick super pi run with crappy memory timings.

Depends on a few things.
Though, I have received more than that actually on more than a few systems.

BTW my CPU is benchable @3.9GHz in most apps, except OCCTP of course :p:
3.85GHz is stable when using 1.475V not stable when using 1.52V :cool:. I will try to do some veryfication/validation over the weekend.

---

Yep, I get the same thing as far as benching goes... You probably have a better chip than I do, mines not even bench stable at 3.8/1.475v. Just curious, are you on air? My chip does pretty well but it really seems to need the extra v's to get good results... I just need to find the balance between volts and temps to find my max OC.

Quote:

---

PS. I'm starting to see a pattern that OC scales better with volts when benching in 32bit mode. 64bit mode hits voltage scaling at lower threshold. Possibly due to more heat produced in 64 bit mode and/or hotspots in CPU.

---

I think I'll install Win7 (32bit) on a different drive this weekend just to see if I notice any difference in Max OC. I get the feeling your right though, reminds me of the B2 steppings as far as 64bit goes (not so much B3), but the 9600 clocked much better in 32bit!

I'm aslo going to install Win98SE on my 2GB flash HDD and XP 32bit on OCZ SSD. Will be fun testing in 98SE @4GHz if it ever install on my machine :p:

The most noisy part is my GPU though right how, Ive fixed fanspeed of 45%:(

I suck at doing anything electrical though, I even managed to blow up a X800Pro ViVo while pencil modding it. Not because of the pencil, but by measuring Vgpu and touching things with the leads I shouldnt have done:ROTF:

Anyway, I guess Ill get a Thermochill PA120.3 on the bottom and a thin 360, or maybe even 480mm rad on top. But Ill have to ask my dad if he can cut the holes cause if I would try to cut the top holes I would molest the damn case and manage to have the top unscratched:p:

Never done watercooling so Ill have to do some research on how and what to maintain, as well as what to do if a certain block has to be replace (for example new GPU etc).

I think your wrong there though. PhII scales very well, the only thing to watch are the temps.

Im on 1.48~1.49V on air, 1.55V for air is still considered to be safe. With water you can very well push it to 1.6V if not more. Regarding that and my current achievements, Im pretty damn sure this thing is going to hit 4Ghz without trouble. Only reasons why it's stuck on 3.7 now is because I dont trust the MOSFETs 100% yet, my aircooling isnt performing as I hoped and it seems Voltage tables ain't 100% accurate. Actually, as soon as something goes under load I get a 0.016Vcore drop.

I would have agreed with you if this thing was already hitting a wall like my old Windsor F3, but Im nowhere near a wall;) It just keeps on going and going, and for the first time I think air is lmiting me badly.

Also Titan told me Ive the same batch as the first 6.3Ghz LN2 PhII IIRC:cool:

How stable is it?

wont prime for over 1 min so not at all. If I could keep the temp down It could probly be stable with a bit more tweaking.

Heres a new stable clock. Same chip as used on the Biostar board, now on the Asus 79-T w/water cooling. Could probably get more out of the IMC but I wanted to make sure it wasn't a factor....

Nice Pi
I noticed in an earlier post that someone running @ 4.6xGhz hit 15.9s, but your clock(tho lower) is just ms from this.

What clocks do you think it would take to get into the 12s range?

Not sure but like kell5 said prolly in the 5ghz range.... Im going to see if I measure the scaling for the decrese in time in super pi for each 100mhz increase.

Great idea! - imo. this will be my benchmark to jump onboard.

I was going to build a Core i7 workstation this year but I'm just not feeling the warm fuzziness I got when I built my Opteron workstation's(OC value).

So I'm gonna wait for PII silicon to improve and see how things look from there.

I can buy a second video card with the money I will save building an AMD rig :)

Im topping out at 3.63ghz right now, I havent really played too much yet because I was out of town but seems like Im hitting a wall somewhere, and it def isnt temp. I havent really bumped the voltage over 1.38v on the proc either though, anyways here are my results:
http://img204.imageshack.us/img204/3034/test1by3.th.jpg

http://valid.canardpc.com/cache/banner/493381.png

Also debating swapping mobos out if I cant get past this. Is anyone enabling ACC? Not really sure if its applicable as a mobo setting due to it being enabled already on the proc itself now.

It's the vcore probably,for 3.7-3.8Ghz you'll need around 1.45-1.5V(my estimate from known results at XS).If you have good cooling 1.5V isn't that high(1.35V is def.)

So with the vcore at 1.45v it should still be safe? Im using the Noctua U12P in my sig and I have yet to see my proc under core temp exceed 40C. Thanks :-)

Would anyone be interested in my running tests with the spec benchmark for 3dsmax 9? I'm downloading the benchmark for fun but I could test scaling across a range of speeds from stock to 4.1ghz if it would be of use to anyone. I would do solidworks too, but I'm not sure if my version is the right one for the benchmark.

Just a quick recap in case anyone runs into this issue. This was my experience but YMMV. I purchased the Foxconn A7DA-S with the 940 and it will not POST. I took a friend's AM2 chip and it POSTED. Created a USB "boot disk" with the latest bios, P06, and flashed the board. Popped the old AM2 chip out and the 940 in. The computer POST and then booted up completely. So if your mobo doesn't POST, then you'll more than likely have to use another AM2 chip to flash the board first. This is for the A7DA-S board. It seems like those with the A79A-S bios, it POST but only identified the CPU as an AMD unknown cpu. This brings me to the next few quotes:

---

With the P06 bios on the A7DA-S board, the multiplier that I see is in the xNN.N format, not in hex. From what I remember, it went all the way up to x30 as the max multiplier. I don't know if they have made any changes to the BIOS since you guys have flashed it or it's due to the different boards (maybe the NB chipset? 790FX vs the 790GX?). Just my experience.

Please show some stabilitytest-screenies.. like OCCT.. running..
Just to document anything regarding "temperatures" (coretemp=same for all cores on Phenom=one sensor) and other usages than running CPU-Z. :p:

@dawei213:
Some boards/bios'es do not have a problem booting with an "unknown CPU".
Others again will not boot.
My Gigabyte GA-MA69G-DS3H and MSI DKA790GX boot'ed up fine with X4 920, even with a bios "not supporting" PhenomII.
Flashed.. to get "support" (and CPU "ID String") and more otpions in Bios.. for both mb's.
This is the way it should be. There are no special instructions in a new CPU-model that should stop it from booting in a pin-compatible socket.

Where can I grab OCCT?

Here's a little more for you just finished playing with 3dmark Ill run prime a little later... Still not happy with 3.7ghz, I want atleast 3.8 before I give up. Granted this is just 3dmark and not a multithreaded prime instance but here's a little more:

Should be able to improve that score a bit more, You should be able to pull that score at 3.6 with higher NB/HT.

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.

:(:(:(

The good news is that it is indeed a 945 and that we could see some results sooner than later for the 945. Also we now have an idea of how they will overclock on the current platform as well.

I actually sold it for the same price I paid for it + $5 for shipping. If I would have known what it was I would have never sold it, but bought a new MB when they became available.

doh

better luck next time buddy :)

3DM06 does not stress your cores much compared to OCCT.
The cores will never really reach the maximum (stable) temp for your current setup (high end air cooler).

Here is an example from my latest stable testing (I am impatient, and use 30min as OCCt-stable. Note that the temps are still rising somewhat during that session.. I am using water-cooling - 1x240mm radiator).

Phenom II 940BE
Stepping: CACVC AC 0850DPMW 80381
Speed: 3600 MHz
CPU VID: 1.432V
NB Speed: 2200 MHz
HT Link: 1800 MHz
Memory: 533 MHz
Memory Specs: 4x1Gb Crucial Ballistix Tracers PC2-8500 Un-ganged
Motherboard: MSI K9A2 Platinum Ver 1.0 Bios 1.7B4
Cooling: Thermalright Ultra-120 Extreme w/ Scythe S-Flex SFF21F in a pull config.
Windows XP SP3

There's lots left.

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.

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.

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:D

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
http://valid.canardpc.com/cache/banner/494259.png
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.

http://img150.imageshack.us/img150/9...zcinepivw9.png

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?

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

Nice OC Lightman: 0848FPAW here

Are you referring to the HT ratio? This doesn't change the NB multplier, just the HT ratio. :shrug:
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!

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 :up:

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.

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?

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?

Got my CPU now: 0841GPMW

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

@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".

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.

I have been trying to hit higher then 4,1 ghz. I found the chip did not need the voltage I was using to try and do this. I was actually able to run Pi 1M also.

Yes it is; Bios 1.7b4. In my previous screenshot, (post 850) look at my cpuz tabs. I have a my northbridge at 2200. The htt is still at 200, with an ht link of 1800. Rams is running at 1066mhz as well. The multi is there and working, it's just mislabelled as HT multi in the bios. I have the NB multi at 11, and the ht multi at 9. Also, the ram timings are buggy in this bios. Alot of the ram numbers simply say "reserved", but after trial and error I have found the correct "reserved" value to equal 5 5 5 15 30.

Thaught it was strange too, have it installed now and worked like a charm from the begining, haven't tried to clock it yet thou that will come tomorrow. The last 5 digits was "80006" so I am hoping it does well even thou its from week 41 :P

I won it on a swedish forum newly started dedicated to AMD. The owner got this for free from the AMD office when the forum came in an article so he decided to start a competition and I happened to be the one who answeared all questions correctly and was picked as winner.

That is pretty awesome at that vcore. I am assuming that you are on water (according to your sig)? Also when you gave it too much vcore would it just lock up or BSOD?

Yes, it would freeze or just reboot. I guess they like less v's....Yes it is under water.

I have been working on getting a good stable overclock I am happy with on mine (same stepping as yours btw - EDIT: I was wrong. I just checked and the stepping is different.) but it seems that too little vcore will make it BSOD and too much will make it just freeze. That very fine line between the two is very fine indeed.

hey I noticed our setups are pretty simular :)
I find that just going up in multi, then fine adjustments on the v's as needed does the trick. I was origianlly jumping to 1.6v- 1.65v when applying 4.2ghz. Even if i set the chip at 3.9ghz with 1.6v, i was not able to complete PI 1M.

on my chip,
stock v's is good to 3.6ghz
1.35v - 1.44v is good for 3.6 - 3.8
1.44 - 1.48 is good to 3.8 - 4.0
1.48 - 1.52 is good for 4.0 - 4.2

if any of that made sense....

You have a much better chip than me. Mine is stable at stock vcore up to 3.5Ghz. I can get 3876MHz at 1.55 vcore. Of course I can get into the 3900MHz range with up to 1.6 vcore, just have not completed much testing to know how far yet. I am trying to sell this chip right now and buy another one to see if I can get an above average overclocker the next time around. I 'm missing my ES even more now...... :(

Nice core clocks,but that 1Ghz NB/L3 clock is way too low.You should try and keep it at 1.8GHz(stock),since L3 access latencies at 1Ghz are going to be quite high and hold up the rest of the chip.

edit: ups didn't see the cpuz picture for 24/7 clocks.Those L3 clocks are much better :)

Thanks for the link. Just flashed it and upped the htt to see if its stable with the new bios.

Not the best board around anymore, but I am hoping for good results as it has been able to create great clocks before, so far it seems ACC isn't even working so I won't be crippled with SB600 (yet) until proper BIOS support for you SB750 people are coming.
