2430557Mhz Memory clock radeon 4850, does that make any sense??

Okay so 3 days ago i discover that my video cards have stopped working. Error message after bootup says Ati driver not there or not functioning.

After a few attempts of properly reinstalling Ati drivers i decided to check with GPU-Z to see whether the cards were being detected at all. Sure enough they were, but to my surprise...the 2nd 4850 has all screwed up readings.

-1C, 250Mhz Core clock, 2430557 Mhz Memory Clock, 1435555.6 GB\s bandwidth

Its all messed up. I tried each card by itself as the only card in the primary pci-e slot and I have determined my 2nd 4850 IS WORKING. yet the sensors are still displaying crazy things.

Does the card need to be RMA? I am going to try a few things before hand though. I have returned my CPU to stock settings. I was running my Q6600 at 3.2Ghz stable for nearly 2 weeks when this started 3 days ago.

Here are my specs:

Asus Rampage Formula

Q6600 B3 (currently at stock, during time of issue was at 3.2Ghz 400x8) Arctic Freezer 7 HSF

4x2GB DDR2800 Corsair XMS2

2x Sapphire Radeon 4850 512mb DDR3 (first model with reference cooler design SKU: 21132-00-20R)

MSI TV@nywhere Plus tuner

Western Digital 160GB 8mb IDE, Seagate 320GB 7200.10 16mb SATA3gb, 2x Seagate 500 7200.10 SATA3gb, Seagate 1TB SATA3gb

OCZ GameXtreme 700W

Anyone else experience such or any info on the matter please? I need to be back in the game to post new scores in the benchmarking thread :P

Nice overclock on the card

try updating drivers, gpu, chipset etc
does the card artifact when gaming?
if none of these work, speak to ati, a reflash of the video cards bios might sort it out

gud luck

Nice to know im remembered Dngrsone loll...Quick update then on the situation

Both cards are fine, i dont know what caused the error. Im guessing temp issues, these things run so damn hot (Fan never goes above 5900rpm and holds the temp around 92C even though manually i can get it to run at 9900rpm at the risk of it sounding like a jet engine)

What I did, remove faulty card, remove drivers, restart, safe mode, remove cards from device manager, restart, install CCC 9.9 with good card. (was running 9.6 before), test, works fine, remove good card, replace with faulty card. Whoop di doo...its working :S

Remove "faulty" card, put both cards back into their previous configuration, intended on doing a clean install of drivers, loads straight into win7 no prompts no nothing, only asks whether i would like to enable crossfire. Of course i go into settings to manually verify. Run a few 3dmark benches, all seems fine and no problems since :S

I think with winter rolling in temps are generally below, currently im running with side panel off. I just picked up a vendetta 2, have to reseat the thing before i put side panel back on...will try tonight and see what happens during a regular gaming session in overlord 2.

They're still problems - a GPU won't run at 90C and the fans don't spin at 9000RPM either. I recommend emailing the manufacturer of the card and they might provide a video BIOS update. It sounds to me that the cards BIOS is dodgy. Good Luck

Unless 4850s DO have kettles for GPUs and a jet engine for a fan.

I hear ya, although GPU's arent designed like CPU's. I remember the good ol Geforce 6800 series, they were designed to be able to withstand 120C. It never would go that high but i believe it would have been at that temp that the GPU would shut down to prevent damage.

Im looking through the interwebs to find the thermal spec for this card right now or at least find other people's reported temps.
