I'm still using my XFX 7800GT, haven't done any serious overclocking yet.

What's your max OC, and core temperature? Also, what's the maximum temperature for the core itself? I read somewhere that it was about 110C.

Did you do the BIOS voltmod? I'm so far at 505MHz core and 1135MHz memory with the 1.5v voltmod, didn't get me any extra overclocking headroom but it stabilized things at higher speeds.

What's your 7800GT model anyway?

Well you could give it a try, as it only adds an extra 0.1v to the core. Mine shot up a mere 5C after doing the mod, which help me attain stability at high clocks. Not bad for something which takes less than 5 minutes

Seems like I'm the devil here instead of you

Haven't been doing any overclocking lately, been busy with stress tests for my recent proc overclocking. It should be confirmed stable anytime soon, then next would be my 7800GT

Mentioned a few posts back, XFX pre-overclocked. 505MHz on core starts to give me small artifacts, backing down to 500MHz solves the problem.

I did RTHDRIBL runs with my memory on 1300MHz, but crashed shortly after. I'll try 1275MHz if it works.

Back with updates. Core speed is stuck at 500MHz, as 505MHz would cause flickering textures. As for the memory, 1150MHz was the highest I could go without encountering any lockups during overnight loops of 3DMark06. Funny thing is, RTHDRIBL would happily run all night.

Anyone knows of better stress settings for RTHDRIBL besides increasing the multisampling rate and detail features?

So far, it's still one of the best DX9 cards out there for it's price-to-performance ratio.

Funny, back during those days excessive memory overclocking will show warped and flickering artifacts while excessive core overclocking will cause white dots on textures. Now, pushing memory speed over the limit will run perfectly till the whole PC hangs, and with core speed pushed too far will cause flickers on textures. Things have seriously changed

Mine goes even higher than yours on load, so there's practically no harm in OCing it a little. I've heard that the core can withstand temperatures up to 110C, if that would incline you to push it over the edge

Still with my 7800GT, plays Borderlands fine, GTAIV and most games as well. Come to think of it, it's worth buying a high end card which can last you a few generations
