Mem Clock Help

post #1 of 8
Thread Starter 
Does it ever become redundant to overclock your memory clock? Is there a max you shouldn't go over even though it's stable?
post #2 of 8
Overclock.net, the pursuit of performance. You could argue that about any component, whether it's GPU, CPU, memory or whatever. It all comes down to what you feel comfortable with running and whether or not it's stable. But in general I would say no, there is no predefined limit.

I don't care about a limit... I am wondering is if you are your mem clock max Mhz, will the performance actually go down due to not enough power? Or because the core cannot keep up with the mem speed there creates a bottleneck... or something to that extent. Does that make sense?

1: If you're card is not getting enough power, then it's not stable.

2: you're rig states you've got a 670, so you're most definitely not having too much memory bandwidth, whatever way you look at it.

So, I would OC it as much as you can while being stable of course. Along with the core clock.

Core is +110 and the mem. is +650 but it is passing hours upon hours of testing. Really no one else has a memory clock this high. I am worried...
post #6 of 8
Are you using the same one test for stressing? Use a few different ones. Don't bother with synthetic stuff for the 600 series, use games, and heaven.

Also, lucky you tongue.gif I'd be more worried if the memory wasn't overclocking at all, ...like my own card. Can get nearly 1300 core, but cannot oc the memory at all without crashing lol

I am on hour 4 of Heaven. I don't know when I should stop... But, when I do, I want it to be 100% stable.
post #8 of 8
Look, if it was going to crash/artifact in Heaven (generally speaking) it would have most likely done so by now. If you want to continue testing, just load up the game you're playing at the moment, and play it.

Or, load up the most GPU demanding game you've got atm.
