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?

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?

**Oldguy932** · 01-23-2009, 09:32 AM

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

Is this on the Vapo?

**pershoot** · 01-23-2009, 09:57 AM

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

).

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

And of course 1/2" tubes, going to be my first watercooling setup though

Lets see where this beasty CPU will land

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...

**Oldguy932** · 01-23-2009, 10:44 AM

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.

**Zeus** · 01-23-2009, 10:47 AM

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.

Ahhhh. OK. I do recall this. Thanks.

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.)

**vfx** · 01-23-2009, 04:50 PM

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.

Feel free to respond to any of my messages man, I appreciate your input!

BTW my CPU is benchable @3.9GHz in most apps, except OCCTP of course

3.85GHz is stable when using 1.475V not stable when using 1.52V

. 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.

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!

Yes, TT 120 Ultra + 12cm low RPM fan.

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

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

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

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

**Particle** · 01-24-2009, 06:03 PM

Last updated two days ago. *shrug* I haven't seen anyone submit anything. (PM me if you have an entry, otherwise I have to sift through gobs of posts)

**highoctane** · 01-24-2009, 07:30 PM

Heres mine to add to the list

CPU Model - X4 940
CPU Full Stepping - CACVC AC 0850BPCW
CPU Frequency - 3600
CPU Vcore - 1.475 in bios, can probably be lowered but this is definitely a stable
NB Frequency - 2200
HT Link Frequency - 1600
Memory Frequency - 800
Memory Configuration - 4x1gb
Memory Ganged/Unganged - Unganged
Mainboard Model - Biostar 790GX A2+
Cooling Type - Air/Freezer 64 Pro
Windows Version and x86 or x64 - Vista 64

**roofsniper** · 01-24-2009, 08:11 PM

24 hour 16 minute prime yea id say it is stable. at first i thought it was just 16 min. surprised you got that biostar board lasting that long on prime especially with cpu temps at 60C.
