I'm planning to buy the following mobo and cpu bundle. http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4910400&Sku=B69-3101

I'm wondering at which ram frequency should i choose? I hear higher frequency does not translate to faster speeds. What i do want is ram that is best for my usage. I plan to use it as a backup server with the possibility of virtualizing 2 OS's.

Which ram and at which frequency do you recommend for my specific mobo?

Please Download CPU-z [ cpuid.com/cpuz.php ] and attach screenshots of the "memory" and "mainboard" tab so that we can recommend you on what to buy. – Sathya♦ Sep 14 '09 at 17:32
Cool link but i haven't actually bought it yet. – burnt1ce Sep 14 '09 at 18:15
burnt1ce - "bought it yet" - bought what? CPU-Z is free, the link can help us suggest the bet RAM for you – Sathya♦ Sep 14 '09 at 19:10

Sathya - Read his question. He hasn't bought his motherboard or CPU yet. He posted a link to what he was planning on buying and is looking for advice on what RAM to buy if he gets that package. It's the very first line in his question. – MDMarra Sep 14 '09 at 19:15

Frequency is not the only issue here.

Since you plan on using this as a server machine, you should use ECC RAM; the page you linked to says it's supported.

RAM timings are also important.

There are 4 timings usually shown on RAM statistics:

  • CAS Latency - Lower is better
  • RAS to CAS Delay - Lower is better
  • RAS Precharge Time - Lower is better
  • Row Active Time - Lower is better

These are usually shown as a series of 4 numbers separated by dashes. e.g. 5-5-5-12

1066MHz - this is the fastest speed that mobo supports. do it up. higher freqs do actually translate into slightly better speed as it allows the ram to operate at higher speeds.

Make sure you get RAM at a frequency that the motherboard and CPU together can support, read the manual. Buy stuff within spec, and avoid overclocking, and you won't have any problems.

don't forget to mention latency. – caliban Sep 14 '09 at 17:34

www.crucial.com will inspect your computer and tell you the memory you should be buying for your mobo. Just because you buy a faster RAM chip, doesn't mean your computer will support it. It will work as far as working goes, but you will not be getting the speed out of it that it is designed for if your mobo doesn't support it.
