GPU core vs. mem

Telecaster · 14 Jan 2015 at 13:30

So I'm quite new to overclocking and was just wondering about the relationship between GPU core clock and mem clock, are they linked in any way or is simply just a case of finding the stable limit of one and then doing the same for the other? Or can one have an effect on the other?

Thanks, what I was trying to get at is whether one will effect the other's overclocking performance? So if I find the limit of the core clock will that stay stable no matter what I do with the mem clock?

Will give it a go. Are the signs the same when either are unstable, or do they fail in different ways? I'm just wondering how you tell which is causing instability.

Telecaster, which card are you ocing?

It's only a 750ti, nothing beefy. So far it's gone from 1080mhz boost to 1380 and from 5700mhz on the mem to 6600. It ran Firestrike and Heaven a couple of times with no problems but last night the display driver crashed at random times, I'm guessing it was the memory.

Cool thanks, I'll keep an eye out. Great card BTW, for the money I can't fault it, passive as well which is great.

Completely passive, idles @ 24 degrees, left it running Heaven fully overclocked whilst I went and did some stuff, came back and it was at 52 degrees.

That is in a tiny MITX case as well, impressive stuff.

Yeah, I fired up Hitman Absolution the other night for the first time and whilst not fully maxed out settings it can run it much higher than I expected, @ 1080p of course.
