overclock setting for msi 7950

[ayayay]

I'm wondering what the best settings would be to overclock  my three 7950 msi cards-- using afterburner  thanks

I have 4 7950 MSI twin frozers at 80% fan speed, 1080 clock, 1250 mem at 620 - 635 khash very stable.

I have almost identical numbers - at 1075 clock.  I have 3 system with these cards - each one has 4 of them.  Powertune at +20, Clock at 1075 voltage as low as I can get it before the cards go SICK/DEAD, intensity 19, gpu threads 1 and I get at least 625.  One of the systems is more stable and I have it at 1100 and get 650.  One is less stable and I have to use intensity 18.

looks great-- will it matter if my rig is inclosed in a coolermaster box and currenty I show 88--77- and 75 degree temps at default values

I try to keep my 7950's at less than 80 degrees.  Right now my highest cards on each box are 73, 72, and 74,  They have been mining rock solid for several weeks now at that temperature.

Yo dude,

Every Die is different ever so slightly, so like myself you may find that in a single rig with 4 cards, each card has a different OC Setting, Core & Memory Clocks stay about the same but Voltage can vary greatly from card to card.

Just my 2 cents, Good Luck, Takes me about 2 hours a card for Stable Max OC. Keep ur temps below 90, safe temps for most tech. Although auto shut off would be 115ish so there is some room for movement just be VERY careful.
