Core Vs Memory

[Sagi3]

I am overclocking my 8600 GT at the moment and got to wondering as to which is most important when it comes to a power increase. What say you?

They are both very important, but since the 8600GT is cramped by a 128bit memory interface I would lean toward the memory.

Mine has 256 Gddr3 memory though

The question is a general one though thrown open to the board no matter what the card.

Clock speed gives greatest performance boost in my experience.

It is on a 128bit memory interface though...these means the bandwidth is quite low (20something gbps), which severely cripples the performance of the card.

Just try to clock both core and memory as high as you can though.

Fair enough. Thanks for your input.

However i didn't intend for this post to be card specific. In general


Core V's Memory?

Well in general the Core will have more of a direct impact on performance.

I can't seem to clock my x1900....I put the core up, by as little as 5mhz, then when i try running a game (crysis demo) it just goes to a black screen once i've loaded the level...as if the monitor doesn't support the resolution...

That's odd, have you tried installing the newest drivers. My x1900 clocks up to 790core...but I'm on water

yeah I'm running the 7.11's...And using ATTools latest version also (1.3.6.1042)

It will clock to it, load the demo, then as soon as it goes into the demo itself (ie past the loading screen) the monitor cuts out and goes into standby...the only way to rectify the problem is to do ctrl+Alt+del so it goes to my 2d clocks, then alt+tab back into the game again.

But obviously that leaves me with running the lower clocks.

yea but.. it can change from card to card.

it depends whether the card is (Bandwith) limited, i.e memory, or whether it is lacking raw processing power (GPU) however most cards will be relatively balanced, thus gains will be better, and more consistent when memory and core is raised.

not really sure why you would do one, and not the other for the majority though.
