What's holding the memory speed back?

[Hornet]

I have a Galaxy Glacier 6800 NU 128MB AGP card.
The memory is rated at 2.2ns which could go way up to 900MHz
Core temp all the time never exceeded 60c

Now when i tried o/cing the memory, it could only do 790Mhz, which IMO is pretty low for a 2.2ns chip, isn't it? So i'm wondering what's holding it back?

Could it be my iCute 450W PSU? ( i heard that iCute brand isn't good, but i don't really have the budget now to get a better one unless necessary)

Is there anything else i can do to get better clock speed without artefect?

Thanks for any opinons

Well... You might want to try actually cooling the memory modules. Core temp notwithstanding, they will get hot if you clock them high.

Your memory's max (@ 2.2ns) is 908mhz, However, you have to understand that not everything out there is comfortable running at full speed 24/7. The fact of the matter is that I'd say most PC3200 ram (200/400mhz) you see nowadays is far below 5ns, simply because it's commonly accepted that there is a "margin of error" for lack of a better term. - Nobody out in the engineering world takes the scotty approach and plays pessimistic.. your 2.2ns ram might only be able to achieve 2.5ns in "real world" application. That could be through any number of factors.
