Which brand is your card (e.g., HIS, PowerColor, Diamond, Sapphire)?

Also, are you able to run the memory at least 1100 at that core speed? I found that the highest stable I could achieve with the Diamond 4870 XOC BE on air was 875/1125 at 1.358V core, 1.501V memory and 850/1150 at slightly different voltages. Either way, I did not notice almost any performance gain when compared to say 825/1125...

Well I have been using the Diamond 4870 XOC BE and ASUS TOP BIOS. No real difference here..

Hmm, the 900MHz core I can't get stable. I can get Furmark stable but then Crysis will fail, or the opposit.

Looks like the best possible all stable is about 880mhz.

The mem I havent messed with yet. Stock/water is only accepts about 1025, but I am considering modding the mem as well.

Quite dissapointet that the vmod only gave me about 30 Mhz from the non mod 850mhz oc I had before Though I am quite sure it is possible to bench much higher, as I was able to run ati tool artifact free at 940Mhz.. Maybe not..

Is my problem normal or? Is it possible that a mod will remove the OVP (If thats what causing my problem?)

What do you cool your card with? And how musk can I expect to gain in mem mhz when max stock is about 1025? (Know its hard to predict, but if it is just 25Mhz, I wont even bother). To me 24/7 and stability is nr.1
