CPU Memory Speeds...

idata — Tue, 30 Nov 2010 19:46:07 GMT

What are some of the possable outcomes to using faster memory than the CPU specs?

http://ark.intel.com/Product.aspx?id=37147 http://ark.intel.com/Product.aspx?id=37147 (intel i7 920 cpu, spec sheet)

I use 1333 speed memory. The specs for the i7 920 call for memory speeds of 800 // 1066. Could this cause Blue Screen Errors?

It is best to check the motherboards specification and use memory that has been tested & approved for the mother board. Not all memory is created equal!

In general, If you use a faster memory than the processor supports, the memory will just be clocked down to the processor speed so you paid for preformance you can't use, but "normally" the memory wil have no problems.

The exception is when the memory does have an issue, either because of the type or quality of memory, timing requirements, voltage requirements or other reason like BIOS not being able to identify the memory. When this occurs, a blue screen would be a very likly out come (depending on what the blue screen error is)

I have 'Crucial' in the box atm. ddr3 pc3 10600u 2x 2gb dimms.

Though, CPU-Z max bandwith is: ddr3 pc3 10700 (667mhz) Issue?

If you are running DDR3-1333 the sys will throttle it down to 1066.

But if you are plaining to overclock you are better off with the 1333.
