8800GTX stuck rediculously underclocked. Is it broke?

PESolution · 6 Nov 2008 at 12:19

Hi Gents/Ladies,
Following my recent post (where i got hacked and had ot reformat), upon installing my graphics card drivers and then putting riva tuner on to overclock, i wasnt able to detect any frequencies. I have also tried Ntune and the EVGA one, and none of the programs detect anything other than 0mhz on both core and memory.

If i look onto a monitoring tool it reports that my core is running at around 297mhz and my memory is something stupidly low too (i will post the exact figures when i get home from work).

Is my graphics card stuck in 2d mode? Is it broken? Any ideas? Ive used driver cleaner pro, tried different driver versions (the most up to date full release and the beta ones for farcry2) and still no luck at being able to get my 8800gtx to work at even stock speeds.

I cant take this lag for much longer! HELP!

Thanks in advance

If you've tried different drivers etc, then it does sound like its faulty. RMA!

If you're feeling adventurous, flash it with a different 8800GTX BIOS, it might fix it.

I got my GTX near release.... Will i have warranty?

edit: further info on card, its the Gainward one

You could do with running GPU-Z to see what frequencies it reports. Standard speeds for GTX's is 576 core / 900 ( 1800 ) mem and 1350 shader

EDIT : is it getting enough power, if not you may find the nvidia sentinel has kicked in and reduced the clock speeds.

Mine is running a lot slower than that. And in games performance reflects that with serious lag. As i say when i get in from work ill post the exact speeds, reported form GPU Z and the other monitoring tools i have.

As for the power, i havent changed anything, or added anything recently to my PC so i cant see that being an issue. I have a tagan 680watt i think it was.

To go back to the guy who mentioned RMA. Does anyone know what my chances are on going to gainward and asking for a replacement?

having looked into the gainward website and the fuss that you have to go through to get an RMA (postage which you have to pay for etc to germany, and then postage back, and proof of purchase) this is no longer an option. It looks like if i cant fix this im gona have to by myself a GTX280, poor me

Depends if you have warranty or not. Some manufacturers have longer warranties than others.. I just said it incase you had one

Only you will know if or not.

after googling and googling i cant find anywhere that stated how long my warranty is on a gainward 8800gtx

MooMoo444 · 6 Nov 2008 at 13:41

When and where did you buy it

Happy · 6 Nov 2008 at 13:42

8800GTXs don't have 2D clocks, they are power eating monsters

I had this after I changed to ...43 drivers, I just uninstalled Rivatuner, then uninstalled the graphics driver, reinstalled said graphics driver then Rivatuner. All is working as before now

feb 07 i believe, and from the mighty overclockers

MooMoo444 · 6 Nov 2008 at 13:44

Well it says on the gainward site all RMA's etc are done through the seller instead of gainward directly. So your best bet would be to get in touch with overclockers, if you're deffo sure theres something wrong with it.

And with any hope, the range has been discontinued and they will be forced to upgrade me

Is the card getting sufficient power? All high-end NV GPUs downclock themselves severely if they don't get enough power. Same if they start overheating.

MooMoo444 · 6 Nov 2008 at 13:54

Yeah but you need to find out if you have a warranty first

As i say ive been running this setup for nearly 2 years now and havent changed anything so i cannot imagine it being power related. Additionally it cannot really be heat related as it happens from boot

Under GPU-Z does it report PCE-E x16 @16 under Bus Interface ?

Also what are the core, shaders and memory clocks for both the bios and current settings ?

Double-check your PC bios too for PCI-E @ 100

i must admit i dont understand half of that old chap! When i get home from work (around 5:20) i will post screenshots of GPU-Z. I would much appreciate some feedback then!

Cheers

EDIT: i havent changed anything in the BIOS and this has only just started happening to me post reformat. Im thinking of reformatting again with Vista 64 instead of 32

PESolution · 6 Nov 2008 at 17:30

Ok guys heres a pic of GPU-Z. As with the other programs clocks are reported as 0mhz....

ten80p · 6 Nov 2008 at 17:44

Unfortunatley that does look like a faulty card

If it were me I'd remove drivers one last time, run driversweeper / drivercleaner again and install latest WHQL certified drivers

Then install latest Rivatuner and see what it reports clocks at, If both GPU-Z and Rivatuner still report no clocks then it's gotta be the card surely

Have you a 2nd PC that you could put GTX in and run GPU-Z on that too ? Suppose it's possible your PCI-E slot on motherboard is dicky
