I'm a little concerned about a build that I put together yesterday. It is as follows:
MB: ASRock Fatal1ty Z77 Professional
GPU: GTX 480x2 SLI
RAM: Mushkin Enhanced Blackline 16GB (4GBx4) 2133Mhz
OS: Windows 7 Professional
SSD: Vertex 4 256GB
I was reading up in my Mobo manual and I noticed a curious sentence in the section on installing memory:
For optimal compatibility and stability while overclocking memory
frequency, it is recommended to install one memory module on
DDR3_B2 slot or two memory modules on DDR3_A2 and DDR3_
Will this quad kit 2133Mhz memory that I purchased work? This sentence makes it seem like any OC memory would be limited to 2 DIMMS. The Mobo specifications state that it will accept 2133(OC).
I've never built a system like this so I'm not sure how OC memory works. I know I will have to go into the bios and manually adjust the frequency and voltage. I'm assuming I just will set those values to what the memory manufacturer says they should be?
Should I just go ahead and plan on returning the 2133 memory and trade it in for some 1600 (which I know will work)?
DDR3-2133 should work fine as a fully matched kit, the DIMM slots referenced assumes 1 stick or 2 sticks as the preference for a typical Dual Channel kit -- a 4x4GB kit assumes all slot are occupied -- those are the first to fill.
The, assuming Mushkin Enhanced Blackline 994015, have CAS timings more suitable for Quad Channel i.e. X79 but should work okay. It's more a problem for the X79 to use a 4x4GB Dual Channel than visa versa.
It's true that it is a dual channel board and I'm installing a quad channel kit. I assumed it wouldn't be an issue because I was under the impression that the DIMMs in a dual channel kit were the same as the DIMMs in a quad channel kit, there were just 4 of them instead of 2.
I DO have the option of returning the Mushkin kit (994015) for a refund in favor of a dual channel kit instead. The dual channel kit just costs a bit more. Is there really an advantage to having 2 larger DIMMS vs. 4 smaller ones in a dual channel configuration?
