OK so, I bought an XFX GTS 250 from eBuyer.com. The website, box and reviews say the memory clock is 2200Mhz. Yet when I view it in RivaTuner it says it is @ 1100Mhz. I have tried to use Google but all it shows is that some have 1100 and some have 2200. Help please?!

ddr2 times it by 2, atleast i think it is, anyway yeah dont move the memory when oc'in it i find mine gets unstable very quickly but the shader and core clock can be wacked wayy up

It's always like that, can't tell you why though, but it's right.

It's GDDR3.

Cryptedvick

its multiplied by 2 ... so the real clock is 1100mhz and effective clock is 2200mhz

for GDDR5 it gets quad pumped ... so 1100mhz is an effective clock of 4400mhz

Old thread, but, I nocited your GTS 250 is clocked quite high. When I get mine a lot lower than that it artifacts a lot! Like 795 Core artifacts a hell of a lot. But you have 830?! Temps are fine, maybe it's just the card? Any ideas guys?

Yep. No 2 cards will overclock alike. It's all luck of the draw.

Harrier

Ahh thought so. It's a rather large gap though 793Mhz core and then it artifacts so much it looks like lighening. Oh well!

Whilst on this topic, would a memory overclock be worth it? I'm running at the max for the core/shader, but I want to know about the memory. I'm aware it produces lots of heat and stuff, but will it be worth it? I play CoD4/5 and stuff like that, no Crysis or anything stupid!
