I read that some brands like Zotac (and Palit maybe?) tend to use only Samsung memory and not hynix. Is this correct? I could get my hands on some Zotac AMP! 3GB, hesitating...
No. Got 4 zotac amp today and the all are hynix. 19.5 Mh max
I feel your pain. That was me a few days ago when my 8 ASUS were all Hynix so I returned them. Did you get the 3 or 6gb version?
Today I found Zotac AMP's 6gb and they all have Samsung memory. These things overclock so much. Right now it's at +800 with zero artifacts. I love these cards so much that I'm considering doing another order!
