CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model CMZ16GX3M4A2133C11B

Pros: cheap ram

Cons: wont run at correct speed even if you set manually

Pros: heat sinks are awesome and looks pretty.

Cons: refuses to run at any assigned speed and defaults to 1333.

Other Thoughts: Corsair has a terrible support system that it'self today is having technical issues and no other information came with the ram about setting timings, so now i have expensive ram stuck in limp home mode, THNX. don't bother posting a "we're sorry please reply to this link at corsair.contact" because that flow chart of a help desk does not work.

Manufacturer Response:

Dear Customer,

We're sorry for the inconvenience and also for the troubles you're having running your system at the stated speeds. But to clarify, most motherboards will default to 1333MHz for memory speed unless it was set to load X.M.P. automatically.

Without knowing which motherboard you're currently using, it is difficult to determine what the issue is. Although we can suggest that you check the compatibility on the Corsair Memory Finder, just fill in the appropriate fields and it'll show you which memory kits will work on which motherboards. You may also want to check to see if your BIOS version is updated, if it isn't you should update it. Also you should go into your BIOS and make sure that the X.M.P. profile is enabled. If you've done all of that and continue to have issues, you should contact our Tech Support at 800-205-7657 or if you prefer you may post on the Corsair Forum and there are plenty of people who can help you there.

Thank you,
Corsair Customer Support

Pros: X.M.P. ready

Cons: X.M.P. dose not match listed specs. Timings here are 11-11-11-27, X.M.P. gives 11-11-11-30. Not a huge deal, but buyers should know.
Can't get the system to boot to X.M.P. values. I either have to under clock it to 2000, or push the voltage up to get to a stable boot. Since I am O.C.ing anyways I don't see it as a total loss.

Other Thoughts: I haven't tried switching the dimms around yet to see if that stabilizes things. Unlikely to help, but you never know.

Pros: Quad-channel kit, stock voltages for rated speed, blue color

Cons: Make sure you get the right i7 to support these bad boys. I have the i7 3820 for now and my Asus can only get them to 1922 for now.

I've been waiting for the Ivy Bridge CPUs, but wanted to make sure my board and RAM worked so I got the bottom barrel LGA2011 cpu.

Other Thoughts: Like I said in the cons, get the right CPU for the RAM!
