With the discussion around memory centering around Samsung/Hynix mainly I've noticed my 970 has Elpida memory. Never heard of it - should this be a concern? Does anyone else have Elpida and can they share their experience?
 
 

The Elpida memory meets the same performance criteria as the Samsung or Hynix memory.  Overclocking is luck of the draw as always.  I have seen some people with very poor overclocks with Elpida memory and others with abnormally high overclocks with Elpida memory.  Don't believe the hype (Striker).

I probably should of been more descriptive with my comment, it wasn't based upon hype. I have owned a 290x and a 7950, both had Elpida, every single Hynix card out there with the same GPU people attempted to overclock in the hardocp and overclock.net forums were better by atleast 100mhz.  It's just even the worst Samsung and Hynix chips I have seen people post about will probably overclock better than the best Elpida. Others in the forums with the same cards as mine (Sapphire reference 290x, Powercolor reference 7950) with Elpida memory all clocked around the same, if not worse speeds than me. Overall it's not a big deal, we are tallking what, 1 maybe 2 FPS difference?
 
As the Vlada011 above mentioned, Samsung at one point had a shortage of GDDR5 chips so EVGA had to switch to Elpida on the 780 Classified for a brief moment, take a look at all the comments in this forum for it, the chips simply do not preform as well with overclocking. Needless to say there was a lot of people who felt they got gypped when they got the Elpida batch.

OP, if you don't intend to OC the memory it makes no difference what brand of memory is used and don't worry at all about it. If you do intend to OC the memory, I agree with Striker and Vlad. I have personal experience with two 780 Classifieds that had Elpida memory. I couldn't get above a +100 OC on memory for either of them. Sold them eventually and the replacements were both Samsung and OC much better, at least +250 from what I can recall.
