Goes GPU overclock have the same effect as CPU if....

[ExoMale]

you overclock it too much it will either freeze or go blank?

I know trying to overclock my i3 for a laugh did the black screen and had to reset obviously because it can't overclock, however I have had experience some very slight issues upping older processors, but never come across gpu issue and for the heck of it I have(or had because msi app gone, but gpuz reads overclock?) 5 profiles on msi afterburner for my gtx 750:

1. Stock
2. + 30 core
3. 30 core + 30 memory
4. 41 core + 80? Memory
5. 41 core + 94/95 memory

As I can't seem to find afterburner program now?? I am set on 5, so that's 1100 core 1300 memory 1178 boost with everything else stock settings.

It's a MSI 1gb OC version so the stock clocks are 1059 core 1253 memory 1137 boost, if you turn both to max they both over 2000 which I did that for a few seconds and no crash? Which is why I'm curious as to if it's meant to act the same as a cpu OC? I don't need a stupid high OC, I'm just intrigued as my last 750 was a normal version and was fine with it of an OC, but not very often I OC.

I'm going back a while here, but in "the days of old", pushing the GFX memory too high would result in "sparklies" (white dotting on the edges of textures, or randomly across the scene). Pushing the GPU itself too high would start to result in artifacting (misshapen objects, invisible textures, etc).

Like paradigm says, when you reach the limits at first you will get sparklies and then artifacts. Go any further and you will probably get lockups or crashes. What I found when finding the limits of my 1070 was that at the end of the day gpu overclocking these days is pretty pointless and the gains are not that great. I haven't really bothered since my old AMD HD5850 which was a overclocking beast. Since then it's been pretty disappointing with voltage locked cards making really worthwhile gains virtually impossible. My 1070's stock clocks are 1822mhz boost and 8200mhz memory but has always boosted to 2012mhz by itself and never drops below 2000mhz so that is what I let it run at. When I first got it I clocked it to see what it can do and found it has a max of 2114mhz on the core and 9914mhz on the memorybut decided that for the small performance boost I would let it do it's own thing and run at 2012/8200mhz.
