9800GX2 poor performance

chickennoob · Sep 27, 2009

I have an eVGA9800GX2, it's performance is so bad. I got only 12k in 3Dmark06, poor FPS in every game I test. I have to say it's performs like a single 9800GTX. And what so strangle is when I disable 1 core, the performance still the same. Which make me confuse is GPU-Z, Device Manager still recognize both of my GPU, nothing wrong except the Performance. I've tested it with ATItool and no Artifact Detected, what's wrong with my VGA? Please help me :confused:

PS: I'm using newest WHQL Driver from Nvidia.com

Fill in your System Specs in the User Control Panel first.

Second, check to make sure SLi is enabled in the driver suit.

chickennoob · Sep 27, 2009

Yep, Multi-GPU mode is Enabled. I'm using Windows seven x64, everything is up-to-dated. I can't find any reason for this poor performance, so strange. If one of two cores is damaged, it must not be recognized, right?

why do I have a feeling you just came from an ATI card?

chickennoob · Sep 27, 2009

Just one, HD4850 and I never mind to pick up another red guy.
Btw, my PSU is good enough to handle this 98GX2, both the 6 and 8 pin connector are connected firmly.

Did you delete the ATI drivers before putting in the 9800gx2 ?

chickennoob · Sep 27, 2009

Yes, I uninstall and use Driver Sweeper also, then do an clear installation for newest Forceware.

sneekypeet · Sep 27, 2009

can I get a spec list for this rig in question?

Something isnt right, but Im not certain right now its the card.

Does the HD4xxx still show in device manager?

Assassin48 · Sep 27, 2009

Did you get the latest drivers from Nvidia ?

To me it sounds like a driver is still in your system

chickennoob · Sep 27, 2009

No of course! I removed the 4850 completely.
Here is my rig:
Q8200@2.8Ghz
2x2G Corsair
9800GX2
CM Extreme Plus 650W.
The HD4850 performed better than the 9800GX2 in my system, how shameful.
@Assassin48: Yep, the latest.

sounds like a driver issue...

also when you plug in the power wires to the card do both connectors on the card turn green?

chickennoob · Sep 27, 2009

Yes, they're glowing as hell in my case now.

but are they green?

chickennoob · Sep 27, 2009

Yes, the Green of Nvidia. I see it clearly.

chickennoob · Sep 27, 2009

Could it be the driver compatibility? I don't know but Nvidia discontinued this VGA and I think they may barely care about the compatibility of this new driver with 9800GX2.

Solaris17 · Sep 27, 2009

right, ok can i get a picture of GPU-z please?

i will need the main tab with all the info and the sensors tab please

Ok here you go.

Btw, thanks you all for helping me.

your overheating...what is your card next to?

chickennoob · Sep 27, 2009

Well, nothing. It's just blowing the heat to my two HDDs. Maybe I'll try to remove the cover to see the difference. Turn off my PC now to blow the cover up -__-

JrRacinFan · Sep 27, 2009

May want to take that card apart and reconnect the fan.

Anath · Sep 27, 2009

it shows his fan speed at 0 also...

newfellow · Sep 27, 2009

Correct my 2cents. yeah, now that people mentioning it that thing is overheating like no tomorrow. No wonder on performance decrease. check the fan.. fan spinning? and 88 degrees? ;P

1. I would uninstall NVIDIA drivers all of them.
2. wipe the drivers with Driver cleaner (and check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video this registry key (sorry, if it's wrong can't verify but should have NVIDIA install settings, resolutions etc etc 'key'-folder))
3. reboot, where afetr would check that NVIDIA card is recognized as 'Standard VGA'
4. Check web for last suggested drivers for 9800GX2 & install those.
5. check the control panel that 'advanced' or 3D mode is at 'selectable' on first 3D screen and check the settings on second 3D settings screen.

There's what I would do. Always time to time nice to wipe everything down and go through the 'start' to collect the 200.

2cents

Solaris17 · Sep 27, 2009

ya hes over heating really bad...

i need you to do me a favor...uninstall the nvidia drivers......reboot....windows will install its own drivers....let it happen......theninstall the nvidia driver aain and reboot....dont use driver cleaner or any of that. do what i just said exactly as i just said.

JrRacinFan · Sep 27, 2009

I really don't beleive it's drivers guys. I think it's a hardware problem with the fan.

he said the fan is blowing which means the driers arent picking up his sensors....which means the driver install is bad.

and besides he might just be looking at a diffirent core...one pcb controlls the fan ....but you can drop down and look at both gpu's but only core 2 will sow fan speed...if it shows up as zero on both of the cores then i revert back to my previous statement.
