So, I got a HD 5570 (stock - 650|800)and decided to overclock it a bit. I bumped up the core and memory 50MHz, ran ATITool for 30 minutes and played GTA 4 for a little while to check stability. It was all fine, so i bumped it up another 50MHz (750|900) I did the same tests as before and it was fine. I then put up the memory to 930MHz and everything was good. By now, at full load my temps were reaching only 50C max. So i load up GTA 4 and run the benchmark tool, but while it's loading i get a BSOD.
So i turn my pc back on and immediately use ATITool. And i got HEAPS of artifacts. It didn't say there were any errors, just delta things and there was heaps of yellow lines everywhere. So i downclock my video card 20MHz at a time to see if it becomes stable. I get back down to stock speeds and it's still showing artifacts So, i take my new video card out and reboot. I enter the BIOS and put my onboard HD 4200 core back to 500MHz and save. I go back to windows and run ATiTool, and sure enough i still had artifacts. So i test different resolutions and it turns out the artifacts only appear at the resolution 1152x648 and above. So i run ATITool once again, and it still has artifacts, then i click the close 3D window button, then i click scan for artifacts agin and no artifacts show up... I am really confused as to what is causing the artifacts and any help would be much appreciated Could it be because of corrupted software such as drivers? Thanks.
Extra details: im using windows 7 ultimate 64bit
i have a gigabyte hd 5570 DDR3 model
my mobo is a asus m4a785td-m evo
i have a phenom 550 3.1GHz cpu
1. i have the PSU that came with the Thermaltake V3 case, which has a 14A 12v rail and another 15A rail. I think. here is the specs incase i'm wrong: http://www.pccasegear.com/UserFiles/v3psuspecs1.jpg EDIT: I believe if you open up the PSU, it's really only a 350W PSU.
2. My temps are fine for the video card, however the northbridge temps are a bit high (50C idle - 65-70C load)
3. My video card fan is fine, and the northbridge only has a heatsink. Niether have much dust on them at all.
4. The HD 5570 is my Christmas present, I had the HD 5570 to test for a bit. So, i am now using my onboard ONLY. The artifacts started while using the HD 5570, but I'm still getting artifacts even with the onboard.
So i was wondering could it be because of corrupted drivers or something like that? Thanks you for helping I am only getting artifacts in set areas, and they don't change after a reboot. I am also only getting yellow artifacts on white-ish colours (ex: scroll bars and the imageshack background colour) and i get blue artifacts on the colour of my window borders (A brown, chocolate type colour) Thanks for any help
Thanks for the suggestions, i reinstalled drivers, which made the artifacts worse. Then i installed that new CCC and the artifacts have gone back to how they were.
@henydiah How would i test if it is the PSU causing this, because i now don't have the HD 5570 in my pc yet i still have artifacts. Would a fresh OS install be an option? I just don't feel like buying a new PSU for $100. I don't even have that kind of money... Thanks for ll your suggestions so far.
Alright, so power consumtion of the reference card is 53W. Your card might consume a little more in case it's not a reference model but no more than 70! HD 5570 is only mid-end. Even my Gigabyte HD 5830 consumes only 175W at full load. Therefore a good quality 350W PSU will be enough.
And BTW have you tried underclocking the card under stock clocks?
As i said earlier, i don't actualy have the card in my machine at the moment. I'm running it without the HD 5570 at all. So, the PSU is not the problem here. I will try new drivers and post back later. Thanks for suggestions so far
Well, i tried CCC 9.12 and i'm still getting the same artifacts I've tried defragging, error checking, older drivers, everything i can think of... I've had a lot of BSOD's while using this computer and if they would help at all, how do i upload them? I'll be getting the card again tomorrow (early Christmas cause we're going somewhere else for Christmas ) So i'll see if installing new drivers again for that card will fix it... Anyway thanks so far everyone, it means a lot to me
Got the HD 5570 today and updated drivers and artifacts are gone for now! It looks like it was because i updated drivers for the HD 5570 before, then switched to the onboard and it wasn't updating properly or something (CCC must've though i still had the HD 5570 or something along those lines) Thanks everyone for helping!
