Thanks sir..How about the 12.6beta? And sir what the cause of hang-up while playing..It seems the keyboard does not response...Is it because did not remove the old driver before installation of new?

Better to be safe than kill your card. Plus, it also depends on how your performance is doing at high clocks as better to run 10% below max oc if the 10% increase doesn't net much extra performance (or runs too hot).
I have got my 7850 at 1205 core at 1.162V (GPU-Z) at +20% power everything else stock settings. I do have a custom fan profile. 5 min testing on Kombustor and evrything looking OK. Still looking for the top for the core. Crazy card!

Thanx for the reply, bark..
When I get home, later, I'll start trying how much in stock voltage I can get on the Core speed. My card is 78.6% (or 78.2%, I'm not so sure right now) so it's not bad at all.. If I remember correctly, my stock voltage is 1.16v.. It would be nice how much it can ereach at stock..

Then, I'll start from 1200/1400 to do little increments, like you say, around 5Mhz.. And see how much it can go..

I'll keep posting how it went..

Thanx, and best regards.. wink.gif

your welcome.

I had a chance to do a little more work last night/this a.m. on my oc. Still haven't found the top for the core and I'm at 1250. I did have to bump the voltage a little more and am near the max for that, but I have to say I pretty amazed I was able to get it past 1200 and the heat is very much manageable. At 1250 I'm maxing the temp at 58 degrees C and the fan is at 66%. Can just now notice the sound of the fan.

Keep up the good work Lex and let us know how it goes.

Man, I really wish I could regulate voltage to see how far my card can go... Such a shame.

Which cards allow you to regulate voltage?

This also works for my XFX 7850 BE. I felt so dumb after reading your post on making sure to use the slider bar to see it. Thanks again:D

So what is considered to be the max safe voltage for a 7850? Right now my ASUS DCII is stable at 1200mhz with 1.24v and i'm wondering if it's safe to go higher? My temp tops out at 65c with auto (and silent) fan so I have some cooling headroom up my sleeve.

Hey guys, new to OCing, just finished getting my 3570k stable at ghz, now starting to mess around with my Sapphire HD7850. biggrin.gif

Anyway, I'm sure it's been answered a load of times in the last 100+ pages but I can't read them all!

What is max voltage and safe temps this card should be running at? I 've been playing around with the core, got it up to 1100mhz but any higher and Furmark crashes after about 10 minutes and sometimes I get a pop up down below saying drivers crashed (12.4). Max temps hit about 71°C (fan profile auto, goes up to about 41%). Is this a voltage issue?

Also regarding testing for stability, I tweak something, then run Furmark 1.10.1 for about 10 min, if no crash, bench in Heaven 3.0. Compare and tweak again. is this efficient? Or should I be doing something else entirely?

Thanks guys, happy OCing! thumb.gif

Humm .... so something's gone wrong. I was running Furmark and system froze, all fans came on 100% and I got a blank screen. I had to hold the power button down to get it to restart and know the system doesn't detect the graphics card. Using integrated graphics at the minute.

The last settings I had it at, I believe, were core 1160mhz and 1.165v. I think memory was stock. Again it's a Sapphire HD 7850 (non-OC one)

I've restarted the PC a few times, reseated the gpu, tried it in the other PCIe slot, took it out it back in the first one. Looked in BIOS for PCIe graphics etc. Device manager doesn't see it at all, not even a yellow triangle for an unknown device.

Any ideas? headscratch.gif
