help overclocking asus 5850directCU (pathetic) - Page 2

I'd definitely try baking it.. that's worked wonders for many cards. Basically pull all the plastic stuff off and bake at 392F for 10min. If you want to save the stickers you can heat them with a hair dryer and peel off. http://hardforum.com/showthread.php?t=1421792&highlight=oven

A couple last things to try before baking:
If you haven't done this already.. maybe try underclocking the memory.. the gpu core is where almost all the gains are from anyways.

My Sapphire is non-ref with digital vrm's like on most reference. I also have a XFX non-ref with analog vrm's... Trixx v0.4.21 is the only utility that allows voltage adjustment. I included the XFX bios if you wanted to try it.

Good Luck.. let us know how it goes.

Cant believe I am about to stick my card in the oven.. But I am going to do it.

Also, I did in fact try underclocking the memory. It did nothing, even at 500mhz. I got the same amount of errors in OCCT no matter how low the memory was. I got better results from lowering the core. Even still, with everything obcenely lowered, it still errored out in OCCT. I am afraid to try another bio's, but I will do it if baking doesn't fix it. Cant hurt at this point considering I cant play games as is.

UPDATE: Baked it for 10 minutes at 395F and it didn't fix anything. frown.gif

I dont think there is anything more that I can do other than another than trying a different bios. I just dont see that working though at this point..

That's too bad man.. I feel for you. These are still very capable cards with a good oc. Running out of options here... I'll list a few more.

1) Make sure to disbable ULPS manually... start with a fresh full uninstall + driver sweep/reboot / install drivers 13.1/reboot/ disable ULPS with utility below/ reboot/ install trixx 4.3-4.6/tick disable ULPS in settings/reboot and give it a try.

2) Cool air can do wonders for stabilty. See about getting some cooler air onto the vram chips. Maybe pull side panel off case temporarily and set up a couple fans blowing into the small opening between the plasitc fan shroud and pcb. If they respond to cooler temps then ram sink them.

3) See if there's a way you can reduce the vram timings and or vddr voltage through a custom bios or RBE. On the flip side you could try and see if increasing just vddr helps.

4) Replacement card or upgrade. Plenty of great deals here in the FS section or ebay. I've actually spotted a few, if you want pm me.
