I've recently decided to upgrade my desktop. I purchased an Intel Core i5-750 Lynnfield 2.66GHz, ASUS LGA 1156/ Intel H55/ DDR3 2133OC, and Crucial Ballistix 2GB 240-Pin DDR3 SDRAM DDR3 2133.

I know a fair amount about computers, but I don't know much when it comes to the really technical stuff. I thought this would be a compatible setup, because the mobo supported the ram speed, but I've just recently read on this site that the CPU only supports up to 1333 and not 2133. Is this correct?

If so, I've also read that you can make it work with 1600, if that's true, should I get this instead? and if so, what should I OC it to? I also bought Scythe SCSMZ-2000 92mm Sleeve CPU Cooler.

Any help would be greatly appreciated! Thanks.

Welcome to Tom's Forum! :) 

Q - What MOBO?
Q - How much RAM do you need; 4GB 64-bit and 2GB 32-bit and more for 'Rendering' Apps

In general, I don't recommend >1600 MHz RAM unless you are going to severely OC your CPU; in your case with those sticks >4GHz. Otherwise the disparity between the CPU's memory controller and RAM speed makes the RAM unstable; yes, you can underclock the RAM -- you'll need to contact Crucial to determine 1600 MHz CAS timings. The timings decrease as the RAM speed decrease under 'rated' speeds.

There's no way you want to OC 4GHz with Scythe SCSMZ-2000.

If you post your MOBO then I'll list good compatable Tested RAM. BTW 2133 MHz RAM is NOT twice as fast as 1066 MHz RAM ~5+% faster; it's all about the IC's used.

ASUS LGA 1156/ Intel H55/ DDR3 2133OC- mATX Motherboard P7H55-M Pro

was going to go with more around 4-6GB ram. I do alot of music recording, and qutie a bit of photoshopping.

What would be a reasonable OC with that cooler? like 3.2-3.4? less?
Thanks for your help!

CPU Fan:
Scythe SCSMZ-2000 is good for ~3.2GHz~3.5GHz you 'can' try faster but test with Prime95 to stress and HW Monitor for temps for ANY OC.

RAM:
You need to either buy MATCHED Dual Channel or Quad Channel Set; never individual sticks with your MOBO unless you ONLY want 1 stick period.

I 'want to' recommend the new Corsair CMP8GX3M2A1600C9 which I know isn't listed but works fine with the P55's. However, since you have the Intel H55 chipset verses the P55 chipset I would strongly recommend that you create a Corsair Ticket before purchasing the CMP8GX3M2A1600C9.

Recent Corsair Technical Support:
"The CMP8GX3M2A1600C9 should be fully compatible with the P7P55D motherboard. Many of our 4GB module kits are fairly new and have not yet made it to our memory configurator, but these parts are definitely tested to run on the P55 chipset."
