Are these memory artifacts?

Hi I decided to do a little over-clocking on my gpu - which is already been overclocked a fair bit.
I was playing gta:sa then suddeny i look at this man and he has silver spikes coming out of him everywhere, i tried to take a screen of it but then the whole screens goes like the man was when i take the screen



Am I right in thinking that my memory overclock is too much? doesnt look like a core problem but I maybe wrong.

simple test, just knock the memory frequency back a tad and see if the problem goes away.

As above but that effect can also be due to compatibility issues and drivers.

Can you reproduce the error each time?

Well I played the game and finished it, decided to overclock my gpu and play it again - never had this problem before however I'am playing this game with aa/af on the notch 1 now that could affect things, I've decided to put my memory down a bit im 90% sure its that, if it continues i'll be back here

i overclocked my gfx card ram to 1200mhz and ran 3dmark06...fine. So then decided to play nfsmw and after 5 seconds i had triangles flying around all over the place! I put the ram back to stock and now its fine, im pretty sure thats what u'r experiencing!

I always thought dots were down to ram and triangles down to core?

In either case it does look like it's clocked a little too high!

Its the other way around, i've had sparklies with my vcore and crazy triangles with the ram

ye i keep lowering my core accidently thinking it was that but really its my ram that sux but my cores preety good lol, the core matters most anyways
