garbled video with visiontek 4850

[mikemodano9c]

so i grabbed a 4850 to replace my 8800gt last week. i didn't even touch the cd that came with the card, and made sure to download the "hotfix" drivers from the amd game site (or whatever the hell it is). i installed those and everything seemed fine except for the high temps. so my issue is I can just be browsing a webpage and bam my whole screen starts to go garbled...my desktop icons get all blurry and everything basically goes in the crapper...video isn't locked up, but it's hard to make everything out...kinda what it would look like if you overclocked your video memory too much...

anyway i increased the fan speed but it would still do it at random times...

i downloaded the older 8.6 catalyst drivers and it hasn't screwed up again since...of course i've only been using them the last 6-7 hours though...

i figured the video output went to hell about 7-8 times in the last couple days...really annoying...

i was just wondering if anyone had the same issue...

i'm on a 750i nvidia sli board (p7n platinum)...figure it might have something to do with it...

i haven't seen anyone else complain about this, so i guess i'm the unlucky bastard.

Odd. What kind of temps are you getting, the usual 80s when webbrowsing, or something more?

If you haven't tried it, you might want to check out this thread and manually edit your fan speed. I knocked my stock 80s temps to about 70 by increasing the fan a little in 2D, not enough to really make a lot of noise. Then made a 2nd profile to put it in moderate leafblower mode for gaming. For comparison, with the DuOrb cooler and heatsinks I'm using now, my 2 cards are running at 46 and 51 at 2D.

well after installing the 8.6 drivers from the newest "hotfix" drivers i haven't had any issues...

yah idle temps were around 80C but i had already done the CCC profile xml change to boost to 45 perfect fan speed...idle temps are around 44C now so temps weren't the issue...

the drivers just need to mature, i thought i might have gotten a dud card...but it's just crappy drivers..

changed my fan speed to 50% perma, in my antec 900 I dont hear it. At idle it runs at 48 celcius and in games it runs 65 celcius w/ 690/1083 OC. I could drop the fan speed but i liek to see low temps. I'm still trying to find a way to drop my e8400 temps by 10 degrees

I had the same issue with my eVGA 750i FTW board, was the last straw and I sold it.

i've really liked my 750i board, i was running a 8800GT and never had an issue....the 4850 is running solid with no issues after going back to 8.6 catalyst...

still need a different board now to run crossfire though..

Heh, I was going to almost ask about drivers, but decided "naw, people say that ATI drivers aren't so bad these days, I shouldn't buy into the myth". Well the thing is, I may have been having driver issues too, system was freezing, though maybe the card(s) were overheating or something, but then after see a few "driver not responding" messages when playing COD4 on just one card, and it used to play it fine, I decided to try uninstalling the drivers, use Driver Cleaner in safemode, then reinstall the hotfix. Had no problems playing COD4 in Xfire for a few hours last night.

Good to see ATI drivers are still crap, glad I didn't miss anything from the 9800pro days.

well i got the garbled video in 2D last night, so there is still some issue. I tried the hotfix drivers again but this time I just installed the base drivers w/o CCC/AVIVO/HDMI Audio. It seems when i mess around or open CCC more frequently then I see this issue more frequently as well.

This is really annoying. I don't think I have a bad card, but I think the drivers aren't tested very well. I am leaning towards the nvidia platform I am on in conjunction with these drivers...
