630/1050 good OC for 8800GTX?

[James10]

The maximum stable overclock I can get out of my MSI 8800GTX is 630/1050Mhz. Is that a good overclock for an 8800GTX? My 3DMark06 score is now 11,829, so close to 12,000!

Putting your core to 617 or 630 both yeild the same effective core speed of 621. No point putting 630, unless you can reach 635 which would effectively give you 648.

from 554 to 571 = 567
from 572 to 584 = 576
from 585 to 603 = 594
from 604 to 616 = 612
from 617 to 634 = 621
from 635 to 661 = 648
from 662 to ??? = 675

565=1350
589=1404
611=1458
634=1512
657=1566
681=1620

The same principle also applies when clocking the memory:
from 897 to 908 = 900
from 909 to 927 = 918
from 928 to 940 = 936
from 941 to 958 =945
from 959 to 985 = 972
from 986 to 1003 = 999
from 1004 to 1116 =1008
from 1117 to 1035 = 1026
from 1036 to 1048 = 1044
from 1049 to 1066 =1053
from 1067 to 1101 = 1080
from 1102 to 1110 = 1107

I noticed that in the RivaTuner hardware monitor, but I didn't know if it was accurate. The Nvidia monitor reported 630/1050, so it must be wrong?

Anyway, I've now discovered the memory was unstable at that speed. I'd get a black screen and a "display driver has stpped working" message when running a performance test for 10+ minutes. 1026Mhz is the maximum speed that is 100% stable.

bumping your CPU to 3.5 maybe and 3.6 for sure will get you over 12,000 easily.

That only applies to the shader cores; the ROPs and TMUs still increase to the designated value.

Yea, I dont see how you arent over 12K already.... I scored a 12500 with these specs: e6600 @3.45Ghz, Pny 8800GTX@ 633/1064

well it does looks nice to me, im running 626/1998 effective clock, 600/1800 original oc, i had 14913 marks and now 15110 qx6700 @3.2 effective clock 3.197 via x12 multi stock fsb267 effective clock
