ATI Tool is extremely sensitive and pushes the system harder than most games will. I'd say go with 430/1200, should be fine for normal gaming. I also say I'm not an expert and will not be responsible for any damage caused to your system!

thanks for your opinion. i'd love to hear anybody else's take on this. i'd like to think that i can clock my 7800 to at least the same as the desktop gtx

430/1200

You may find your previous stable overclocking not that stable after you try this GPU killer!

Running this test in loop (up to 100 times) can detect more artifacts than any other games or ATItool. When Quake4 or NFSMW may push my 7800 temp to lower 70s, 30 minutes' Pixel Shader test easily makes the temp pass 100 degrees!

It's a "dangerous" test if you loop it, so be careful not to fry your new card!

well my most recent run of atitool @ 430/1200 lasted almost 32 minutes w/out errors.

I think it's time to pick a speed and stick with it. All this stress testing with ATI tool is probably doing more harm than normal gaming will.

yeah. i'm going to leave it @ 430/1200. ran for an hr using atitool 0.25 beta 9 w/ no problems. hopefully it was something funky w/ v0.24

I should probably update my ATI tool as well, as my card runs fine at 435/1250 and could probably handle more but ATI Tool errors held me back.

When I get home from work I'll probably go for 440/1300 and if it's steady there I'll leave it be. I'll add AS5 soon but like someone pointed out these cards are most likely voltage limited and not heat limited so I doubt it will do anything.

I know we all want to push our cards to the max, but eventually we have to wonder if we'll actually notice that extra 10 or 20 mhz while playing games.

i pm'ed w1zzard in the techpowerup forums asking about the discrepency w/ my scanning results between the 2 versions. hopefully he'll say to use the results from 0.25 beta 9.

Hi,

You can decrease the Vcore voltage to 1.26v. It works fine with me

Tried the ATITool got problems on most settings within a few minutes....although am not convinced just got the new ATITool 0.25 Beta 9 and installed new X-Treme Drivers and now dont get problems on the inital clocks anyways. Currently 440/1200

Has anyone tried running ATITool on stock clock settings? I wonder if it will produce errors too.

I tried it for about 12 minutes and didn't get any errors. However, I played F.E.A.R for like a half an hour and got this weird green pixelated thingy.

I'm going to overclock it back to 450/1200.

I was able to run beta 8 for more than 7 hours without an error at 450/1200 (see my post above). 440/1250 ran for 60 min before I stopped it, but the 3dmark05 score was lower for me than the 450/1200 score so that's where I'm stuck at.

I'm going to try the beta 9 tool this evening on 445/1250 and 455/1200. Both appeared stable in gaming and 3dmark05 but ATI tool beta 8 found errors after approx 10 min. I just want to verify that the tool wasn't the problem.

From the beta 9 release notes: "Artifact scanning on X1000 series might not be 100% reliable yet"

Which leads me to believe it might not be totally reliable on non-ATI hardware yet as well.

Niwotian60, do you have AS5 applied to your 7800? I wonder if I would see a big improvement in temp and clock speeds if I put it on.
