Nvidia 9800Gx2 Club!

is your Qx 65nm, or 45nm?

What voltage are you using for your Qx? I had to use over 1.5v to stabilize my crappy G0 at 3.5ghz.

the GX2 oc'ed does use almost 300w close on LOAD.

Maybe for your system, it's okay. but with my settings, it was not.

65nm quads use up a lot of power which is why they are now primitive.

Firstly the GX2 300W in those links is system load, thats the ENTIRE PC, as I said the TDP is less than 200W. The actual power used is even less. And note: if they measure from the power socket the figures they quote includes psu losses.



Secondly the Q6600, I even gave you the formula. I'll do it for you, I'll guess your VID at 1.2625v, correct it to suit. Your Q6600 is not using anything like 300W.

Pd = 95*(3500/2400)*(1.5/1.2625)² = 195W

With the clocks I've tried mine's using a lot of power, its still quite happy on a 500W psu.

fornowagain what motherboard are you using?

fornowagain what motherboard are you using?

Just an old IP35 Pro, card is stock unmodified. CPU is on water.

I am not worthy

How are you guys getting lucky with your cards core running atleast at 740 and up? Mine tops out at 725 before it freezes up.

you should be able to clock higher

what is the load temp. ?

[wilson]

Does any1 know if BFG warrenty would allow me to remove the stock hs/fan ?
I only ask as EVGA and XFX allow this and it does not void the warrenty and BFG have put a nice sticker over one of the screws that i had to remove to get the case open....

[slugzkea]

BFG does not allow you to remove the HSF. that would void warranty.

XFX does though

[phelan1777]

I will be getting my block soon, in a week or so, then I can start playing with my card and see what I can get out of her.

[Darkatom]

After about an hour and a half of cod4 online my temps are at 80c, While running 3dmark they hover around 75 with the fan on auto.

[cowie]

hey a-r and rlm what up!
man i have the cooling down for benches,maybe its time for a volt mod?
03 stable no artys 792/2000/1130
but not all cards are made the same it seems...a friends card wont go over 730/1800/1140 even in the artic circle(temps 28c 30c)

well, the tem. is OK

try 740/1850/1050 and set the fan speed to 75% it should work fine

[Gunnz Akimbo]

Well i got one, but it don't work.

I can see bios and post information.

After that, all i get is a flashing cursor.

Can't get the safe mode menu either, and DVD's don't autoboot, like vistax64 dvd.

The power LED'S on the back are Green on the top, and Blue on the bottom.
Is that fine?
The PCIe connectors are both green.

Running it on a D975XBX2 PCIe 1.0 mobo with 16x bandwidth.
Flashed to latest 2831 bios, still did the same lockup thing.

I experiense the same problem when first time i use 9800GX2 , and i found out that , there is conflict between my sound card and the 9800GX2
and when i remove the sound card the system boot normaly
put bac the sound card the system wont boot

Seriuosly, not any other thing possibly make it hang?

Because i remove the 9800 and re-install the 2900 and it works straight away.

[slugzkea]

what sound card is this, that is conflicting with the GX2?

[Gunnz Akimbo]

Well i will give that a try, and just noticed one thing in the mobo manual.

The board has 2 pci slots.

The first one is close to the first PCIe, the second one is on the lowest part of the mobo.
The second PCI is SMBUS routed, whereas the first PCI is just pci.

I have the X-Fi in the SMBUS routed PCI slot, so im going to move it up to the standard PCI slot.

It might be a fix, but now ive gotta do alot of mucking around again......

[Gunnz Akimbo]

Well, you were right.

After taking out the X-Fi, the 9800GX2 now works.

WEIRD.

[wilson]

Well your right i got my reply from BFG....

BFG Tech.
Unfortunately it would.
Any "tampering" (defined as any physical or software -firmware- modifications
to the card including, but not limited to, replacing the fan/ heat sync and
further overclocking or underclocking the card) will void your lifetime
warranty (which covers the card for YOUR lifetime, not just the "lifetime of
the product").

Well lets hope i dont need to send it back lol

[koc]

Well, you were right.

WEIRD.

yes man its weird , i dont know what the hell problem between GX2 and X-Fi sound card

[Gunnz Akimbo]

I think it has something to do with the
Nvidia GPU SMBUS conflicting.

Because now in everest, i can't see most of the system activity, like fan speeds, mobo and ram temps, and mobo voltages.

My rig with 9800gx2 worked fine with XP but now with Vista Ultimate I cant run 3D06 or Vantage , 06 had errors for openAL which were corrected by running openalinst as admin but now it gives an error about 3direct or something - but now its running so I dont know .

Vantage gives an error about fullscreenstate failed, it doesnt seem to like my common 22" LCD . I think its to do with my KVM as it seems to error when I change focus away from the benching pc ...

I've allso had this problem with openAL under Vista x64, but try to instal this http://files.filefront.com/OALInstex.../fileinfo.html. It solved my problem and 3DMark is running ok.

[wilson]

Just a bit of info reg my E8400 and my Q6600 in 3dmark 06. With the Q6600 i get 19363 but with the E8400 i got 17860 now i did notice that i was getting higher fps in the tests than with the quad but i guess i lost points in the cpu test. My point is that the higher the oc on the cpu the better the card runs so a none overclocked cpu will probably bottleneck the cards performance.

[RLM]

fornowagain, that's top results you're getting there. 4.8mhz on water

Sweet result man. The cooling certainly makes the difference.

Finally with a bit of tweaking and one OS corruption, due to some over ambitious memset entries, I hit the 22K
