I have the ASUS P8Z68-V Pro and the i7-2600k and am stuck on what memory to get for it. I will be running Win7 64bit and the 2 applications I run are CAD softwear that does some rendering and current Battlefield Bad Company and soon Battlefield 3 in max settings. My video card is the Gforce GTX 480 and some point will have the 3d monitor.
Looking over all the memory that is out there I cant tell what would be better over another?
Thanks all and anyone for your help.
Well you've got your toes in different waters; CAD I think of errors and Gaming I think High Frequency with low CAS.
Cinebench R10 does well with DDR3 1333 MHz CAS 7, errors are lower with DDR3 1333 MHz; Gaming DDR3 1600 CAS 8/9. In most CAD work 16GB or more is best, and recently there are 2x8GB kits but they're expensive but a couple months ago 4X8GB non-ECC was $1500~$2000 recently a $330 kit became available.
Hi, there are several reviews that show that 2 x 4GB RAM is the performance vs cost sweet spot for Sandy Bridge builds. You would have to be a real power user to need more. I think that even though you run CAD 8 GB should be enough. I am not a gamer so I could be wrong. For most people, anything over 8 GB is overkill and you won't see too much difference in performance if you go to 16 GB. Bit-Tech had an excellent article on this subject.
The best RAM to get is 1866 because if you wait for a sale you can get Gskill or Corsair for $75 or less - which is bargain. If you can get a CL 8 it is a little better than CL 9 but with Sandy Bridge it doesn't make much difference.
1600 RAM also does very good job on Sandy Bridge rigs. Anything over 1866 is probably a waste of money unless you are again a super power user (heavy video editing, picture editing, heavy use of very intense math-centric programs).
If cost is not an issue get a set of 16 GB RAM - it certainly will be somewhat faster.
