Clock Speeds and OC?

post #1 of 4
Thread Starter 
This 7900GT has a core clock of 430 http://www.newegg.com/Product/Produc...82E16814121003

This 7900GT has a core clock of 520 http://www.newegg.com/Product/Produc...82E16814150139


If I buy a 7900 GT, do I need to find one with a fast clock speed? Or can I just as easily make it as high as the others. Do they do something to the hardware of the card to make it faster, or is it only software overclock? Can I achive the same OC?

The maker mods the card's BIOS so it defaults to higher than stock speeds.

Can you get a non-o/c'd card to run at the same speed? Well, there's only one way to find out!

it will be a crap shoot of sort but xfx, bfg, and evga will give you the biggest shot to see if a "stock" will oc as high as a "factory oced" card. I dont think the companies will add any extra hardware to the oced models.

You could buy the one with the lower clocks and overclock it but since that both are almost the same price and the XFX offers LIFETIME warranty, I'd go for their 7900GT instead of the ASUS.

I bought my 6800 GS because it had the highest clocks (from the stock) for a mere $10 more, so come to find out the one that cost $10 less clocks as high as mine; 500/1200 for a 24/7 opps.

So XFX GT it is, IMO.
