Without any tinkering in the bios , it can go max to 690 / 920 - this is stable to max, Above this u have to give more vol, cooling and stuff.. And as far as i no, 8600gt has no air flow to its rams, if u can fit few heat sinks on them,and a 80mm fan below ,it might to the trick to achieve more O.c!

Betimi.g Posted March 17, 2008 Posted March 17, 2008 i cant oc it to 920 mem because i say its a ddr2 memory graphic card i cant oc it max to 530 and i ask can i oc it more with any tricks with memory timings or something like that!

kingdingeling Posted March 17, 2008 Posted March 17, 2008 You can not change video card timings, I never even heard of such a thing (I OCed any vid card I've had up to date). Saif means 920 mem as in DDR920. If you want to OC more, the only way would be a volt mod, however you'll need good soldering skills to perform one.

kingdingeling Posted March 17, 2008 Posted March 17, 2008 The voltage can only be regulated with a volt mod, which you have to be very good at soldering for, as I said already. If you can not perform one, then you can not OC more than 500MHz on the memory, sorry. Share this post Link to post Share on other sites More sharing options...
get_saif Posted March 18, 2008 Posted March 18, 2008 As suggested before, if u are not sure with volt mode, do not attempt a trial error, it will spoil your gpu. If u are confident with the approach u have in mind, u can take help from few links hu have discribed in details to volt mod a gpu. Good luck!

Betimi.g Posted March 18, 2008 Posted March 18, 2008 Please help only with tricks of bios in my country i cant buy this volt mods Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted March 19, 2008 Posted March 19, 2008 You don't BUY a volt mod, you MOD your card! That means, loose warranty etcetera. You can not change the volts of your cards core or memory in the BIOS, you can only do that with an ATI card. In your case, you just can not OC the memory higher.
