Hi Guys,

Bought 2x Asus 4890 TOP cards on sat.

Since fitting into my system, they produce sparlies on the desktop and in games upon boot. After approx an hours of use and the temps warm up abit their fine though :confused:


Specs are:

Asus P6T Deluxe
intel Core i7 920 @ 4.2ghz underwater, also tested at stock
2 x Asus 4890 Tops Edition, Temps are fine 60c under load
12gb of corsair ram
3 x 250gb wd re3's in raid 0
1200w BeQuiet psu, more than enough power
all housed in my tj07.

Both cards have been tested on their own and both still show the same issues, my guess is it's a dry joint and when the cards warm up things run fine.

Tested with vista ultimate 64bit sp1 and sp2 also rc of windows 7 ultimate 64bit. Along with cats 9.4 upto 9.7

So im at a loss as to whats causing it. (other than possbile dry joint)

Any ideas lads/lasses? :D
 
Morning,

At work so unable to get pics.

Their basically pixels lighting up like twinkling stars lol. in groups, on their own. All over the place.

best way to describe it. BTW Wish i had just gotten up ha ha!!
 
Hi Blaineoliver,

Its a BeQuiet 1200w psu, and yep both cards have been tested on their own and with 6 pin and 8 pin connectors in place.

Also as mentioned they have been tested with vista and windows 7 and drivers from 9.4 to 9.7. Clean builds in-between.

Hi Guys,

Havent tried them in a diff pc, only have the main gaming rig and my shuttle as a work machine. I have a BFG295GTX which works fine in both slots on the mobo. This is being sent out today though as its been sold.

Both cards work fine guys after a period of warm up time.
 
Sparklies are usually memory related but to have 2 cards with the same problem is strange.

Try underclocking the memory and see if it goes away.
 
Hi Manface & The Asgard,

Will try underclocking tonite, but as i mentioned its odd it vanishes when the cards warm up.

Manface, I have tested with 3 monitors. My Dell 3007 2560x1600, i also have a sammy T260 1920x1200 and also a dell 2007fp which is 1600x1200. Same issue occurs on all 3 monitors.

Cables have been changed as the psu ships with 4 x 8 pin cables which have been swapped around and tried with different connections on the psu itself. I dont feel its a psu related issue. As the machine had been running 2 x 295gtx's at one point ;)
 
Very strange that it goes away when warmed up, but noticed your watercooling so could the -lack of- cooling of the vrm's memory area be a problem?

Would think about bios issues and things like that if underclocking doesn't work.

Oh.. change your PCI-E frequency from 100 to something like 99/101/105/109/110 to see if that makes a difference. I've had a board in the past that would make the gfx card artefact with the PCI-E frequency at stock speed.
 
Hey Scougar,

Only my cpu is water cooled, i dont bother water cooling anything else, im always chopping and changing things.

I forgot all about the pci-e bus speed tricks on ati cards, been using the bfg295gtx for too long, that didnt like the pic-e bus speed being anything above 101mhz. will give it ago. Cheers
