Phenom 9500 w/ MSI K9A2 Platinum

[madfaze]

Ambient heatsink 18C, Outside -1C.





Yes the cores are undervolted from stock! Stock 2.3G is 1.25VID 1.24V.

does the smart fan workin?i had 3pin fan it seems i cannot lower down its speed...

Yep, I've used 113, P0E, P0F, P0H and on all these the 4-pin CPU fan will work to low fan speed at the temperatures you've set it to. Mine idles 1280RPM and it only gets faster when the core temperature starts going plus 33C.

You'll have to use the 4-pin CPU fan connectors with a 4-pin connection for that feature.

KTE what bios is that you posted the SS of in post 977?


also I remember tactic doing some of the best bios modding there was for nf2 have you tried to get anyone to look into the bios ?

ouch! got only 3pin in my zalman 9700LED...

P0E -> no patch and runs 1066 default.

tictac?
Yeah I remember too.. where hast thou gone, oh tictac?
A mod would be brill! If only.

But it should come with a fan controller? (fanmate)

I'll try a 3-pin fan on it to see if it works using the CPU fan connectors. Give me an hour.

just misplaced my fanmate , it used to work before with my k9a2 cf board but t has an option to choose whether a 4pin and 3pin connection,

thanks! looking forward to see it...

[KTE]

I tried a small mod basically because 3-pin won't work (need a wire for PWM) but nope, you'll need 4-pin for that feature to work.

tic tac toe

yea it would be nice. maybe we should contact a few people like -=Merlin=- , tmod, oskar, BigToe, etc....


I'm sure there has to be something they can do with them to make them alittle more overclocking friendly

Shall we do some mods?

I used to keep up with and practise what is covered in here here here here very very regularly but I have hardly any time to think about computer related stuff anymore incl. programming and hence why I quit. Don't remember most of it now but it wouldn't take me long to get back, it's been around 28 months since I left and last had interest in this area. The only problems is, it's too time consuming.

I am trying something though.

thanks!hope that MSI could resolve this thing

[jonspd]

Yea I think we shall I will join in

what do you want to do vtt, vdroop, nb, sb ?

I think the board could for sure use some better cooling then stock have you change the factory thermal paste on nb and sb. I never did. This heatpipe design could be not good and could be transferring heat from the mosfet to nb or vise versa.

[madfaze]

hmm good thing i just put 40mm cooling fan in top of the NB... 8k rpm

BIOS mods.

Trying one now, slight mod only. MSI/AMI mods aren't working much, most BIOSes I tried just adding options in empty trays and unhiding/hiding options but it doesn't work on AMI/MSI BIOS like with Award DFI/Abit BIOSes.

Tell you what, if you want a better stable oc, then cool those MOSFETs and inductors instead of that NB. The RD790 is a very cool chip compared to even the P35 chip and won't need voltage above stock nor get hot even when oc'd.
Once those MOS/Ind get a little too hot to touch, they will start making you get failed stability results IME on this board.

Here, this is what you need to cool, just a little air passing over this area is perfect:




AND in case you guys didn't know, make sure this "PCIE Gen" setting here is Enabled (they're disabled in the image there) for the PCIe lane you're using with your GPU because Disabled means you get PCe 1.0 and Enabled means you get PCIe 2.0 bandwidth.

[Daveburt714]

My machine has been running for a few hours... I checked the heat pipe coming off the MOSFET cooler, a little warm...

Those Inductors are HOT though.. All of them!!

I'm gonna have to get some kind of heat sinks for those... Tall ones!!

Thanks for the tip KTE...

thanks for the tip mate!

this is one of the reason that i changed my mobo from k9a2 CF, it has a circupipe on it...

for the PCIE Gen setup, what i did is set up to auto..is that correct? i had 3870 vcard...

anythin' in mind?!

[KTE]

The MOSFETs are under that heatsink with the arrow on them above, right after where the +12V CPU 4-pin power connector is situated.
Everything which comes before the CPU socket area and after the +12V 4-pin needs to be supplied, cooled and regulated well for best results.

Remember: IC's hate heat and anything which initiates or aggravates its onset.

Right now I'm trying to get stable oc's and by that I mean days without failure under dynamic stress to then result in no immediate degradation as witnessed once before, trying to find a sweet spot. For me, it's very important to establish 100% stability as much as I can after all the initial basic testing before calling it stable to anyone else... boasting isn't one of my characteristics, but honesty and genuineness to the best of my ability is, to give accurate feedback reports, as I want stability the same as a factory oc attains. I can go for 1hr Prime, mislead and get everyone in trouble trying to copy, but that doesn't fit inside the stability criteria for me as I oc systems at the 3 places I work at professionally and so I have a very stern criteria to meet: facts. Usually everything and then Linpack compiled for AMD systems to run dynamic loads at dynamic problem sizes for up-to 7 days, but this time, Linpack isn't running for some odd reason and I've not given it another try yet.

For those who can attain similar MHz as this chip I have, they can try imitating the settings I use. Saves time, a lot of work and frustration.

Lowest I could achieve fully stable so far for 5 days Prime/Memtest testing on and off, cold, warm, reboot cycling, changing MHz and changing them back again, no freezes, no overheating, no lockups or any performance oddities (SuperPi and some similar mathematical computation based software including Prime95 shows instability in one other way: the computation values be abnormally slow, adrift of proportional scaling) at 2.6G CPU, 2.4G IMC and 1066 RAM is the following ->
(click for full size image: todays testing ongoing at typical temps - idles 31-33C, ambient case 20C, CPU fan <2170/3100RPM, 215W AC load):



I have tried lower IMC VID, it failed by passing 3hrs P95 and suddenly freezing.
Second lowest CPU voltage I tried hard stability testing is 1.264V and that locked up the system after 3hrs Prime. 1.272V is the next I've tried and this is fully stable for many days testing yet but there is a lower region in between that 1.264-1.272V which maybe just as stable, I've not tried yet.

If you really want to find best MHz/V then play around with VIDs/HT ref. Different VIDs allow different voltage range combinations. I could only get 1.27V with 1.225VID CPU or lower. If I want lower volts than that (not auto) then I have to drop VID further and set voltage manually.

[madfaze]

anyone has an idea on what size are those circupipes?

you think this would works?

How did you rotate your Zalman I wanted mine to push air out the back but I dont see how the clip would fit in beteween the heat pipes. Can you shoot a pic or tell me how you did it?

[Hosser]

On XS? If so, what's his username?

KTE do all 4 pci-e gens settings need to be enabled? or just the hpet setting?

[Hosser]

Only enable HPET if you're on Windows Vista.

And set all PCI-e lanes to "Auto".

[madfaze]

did that already, anyways enabling those HPET would help boost your performance?!


here's what i did transferred those 40mm right at the mosfet, removed the circupipe sticker...

from this




to this

[Hosser]

HPET has nothing to do with performance, it's just new high resolution hardware interrupt timer. Can only be used by Windows Vista and some modern Linux kernels. Windows XP does not make use of it.

Nice cooling solution, though I'd imagine it's quite loud? How has it affected temperatures/overclockability?

[jonspd]

it was already enabled and the others where already on auto
