HD6850 Sapphire OC-ing

So for now (soon I'll upgrade mobo,cpu,etc) I have a Sapphire HD6850 on an Intel E4400 2.6 ghz oc.
I OC the HD 6850 up to 960 / 1200 and voltage at 1.168 ... The temperature is <75 C on auto fan...

I wonder... how much can I oc this card... I am scared to test... I found this OC config on net on a pro reviewer site lab501...

  1. Have you tried unlocking the card into a 6870? That will bring much more performance than just trying to overclock it. There was an article about doing that on Tom's not too long ago.
  2. I heard about smth like this but wasn't it about 6850 and 6970?
  3. 6950-6970
  4. Oh ... I forgot to say with this OC the 6850 is better than a stock 6870... The question is can I improove more the performance

    Hey again :p Congradulations on your new card.
    Yes it was, I was just going to say that :D
    You can flash the BIOS to a 6870, but it's not going to have the performance of a 6870. The 6950 to 6970 is a diffrent matter.

    Here you can read to what frequencies they got their 6850.It's a great review.

    What is strange, that in diffrent sites, the Benchmarks, are VERY diffrent, some show the 6850 faster and some show the GTX 460. From what I have seen the 460 OC a little better, but not that much.

    I think you shuld go a little bit lower(weird ah) something like 900/1100 and try to run it a closest to stock voltage, but thats my opinion. I dont think 5-6 (maybe) FPS is worth to go over these limits.
  6. Overclocks will vary. Any random two cards (two 6850s let's say) will more than likely acheive very different "highest overclock" settings.

    All you can do is try.

    OFFTOPIC Hy Wolfram23 I see you have got 2? 5850 in CF, and I was wondering, is the AMD 870 Chipset good for CF, I know it's not as good as the 890FX. The Board I was thinkig is an ASRock 870 Extreme 3 which runs Crossfire at x8.

    8x is fine :D

    OK Thanks :D
  10. I managed to get the HD6850 to 1000/1200 with 1.25v and a max of 76 degrees in furmark... The temperature is good? I had a 8800GTS which had 100 C in furmark without OC...
    Can you provide me information about OC-ing this card... and what voltage is dangerous... :whistle:
  11. AFAIK, GPU voltage is a bit vague but your temps are really good. However, definitely use GPUZ to check the rest of the sensors, most importantly what temp your VRM is at (which regulates voltage) as that will see the most temp increase from changing the voltage.
  12. This is what GPU-Z says http://gpuz.techpowerup.com/11/01/14/4se.png

    So it is alright?
    If I get the voltage to 1.3 will I burn my video card?
  13. Idle doesn't mean anything, heat it up with furmark and take a shot of it where it hits max temp. (mouse over to see specific temps on the little graph)
  14. In furmark in xtremeburning mode max 76 C. I took a screenshot but donno where it was saved.
  15. Oh I forgot to add the fan is automatic... and usually is 20-30% in idle... donno exactly in load... But I can say it is inaudible so probably it is at about 50%
  16. Havn't I said above that I got 1000 core and 1200 memory?! I am thinking about getting over this league...
  17. Raising voltage is dangerous?
