PC Build: Memory, CPU, and Motherboard compatibility

I am piecing together components for my first PC build, and I have recently landed on the Asus P6X58D-E as my motherboard, and the Intel Core i7-950 Bloomfield 3.06GHz as my CPU. This i7 will take up to three channels of 1066 memory, so I looked on Asus' site for recommended memory for this motherboard. I want to have at least 6GB memory, with a preference towards 8GB. They list models from Kingston, Crucial etc. in 1GB, 2GB, and 4GB varieties, with the 4GB being 2x 2GB. There is a note on the compatibility chart stating that this memory (4GB Crucial, 2x 2GB) is supported by the motherboard in several ways:

A, 2 modules as one pair of dual-channel memory.
B, 3 modules as one set of triple channel memory
C, 4 modules as one set of triple channel memory
D, 6 modules as 2 sets of triple channel memory

So can I use 2 of the (2x 2GB) kits as one set of triple channel memory, for a total of 8GB? If this is painfully obvious to someone, I apologize, I just want to make sure I'm interpreting this correctly before I commit to any major component. On a side note, anyone know of an i5 cpu/memory/mobo combination that will outperform the hardware listed above at a similar price point (approx. $640 through newegg)? Thanks in advance for any help..

  2. Thanks for the quick reply rolli59, I was thinking that some of the higher end i5's could do what I want. Quick question though, the G Skill RAM is 1600 MHz, won't both of those CPU's only support DDR3 1333?? The RAM says it is specifically designed for the P67 mobo and sandy bridge CPU's..
  3. or does the RAM just run at the 1333 MHz speed..
  4. If you overclock then it is good to have faster ram and that board supports up to 2133MHz ram OC. If this is a gaming machine then the I5 2500K is all you need, take a look at this,2893.html
  5. Thank you so much, that build is right where I want to be price wise for this system. Do you think I am ok with a 650W PSU as suggested? I was looking at some other user's builds and issues, and everyone seems to be using at least 750 - 800W on their builds. Not exactly sure what I'm going to do for a GPU yet, but I don't want to limit myself with the PSU...
  6. Also, this will be for some gaming, but mostly Photoshop and 3d modeling with 3DS Max/Modo. I will not have insane graphics demands, but I will likely have something mid range.
  7. 650watts is enough for a Crossfire HD6950 setup here is a power benchmark for a few of the newer GPU's and that is total system load on an overclocked system
    But then again you can get quality 750watt units for close to same price as quality 650
  8. Excellent, thank you again for the help and information (and links). Looks like I'm going in a new direction with this one..

  10. For 3dmax I suggest the i7 2600K
  11. You'll see most professional builds for 3DMax, CS5 movie editing, 3D modeling landing in in 1366 / nVidia territory. CPU tests which have all other things equal, won't show the benefit of increased memory capabilities. They also love high speed, low CAS memory.

    $477 - Asus Sabertooth
    - Intel i7-960 included in above
    $40 - Scythe SCMG 2100
    $5 - Shin Etsu
    $240 - 3 x 4GB Muskin CAS 7
  12. Nice, I was looking at the sabertooth first before I landed on the other asus board mentioned above in my first post, also seems to be highly rated. So, from what I'm seeing, I should go for a higher end i5 or a better i7 than what I was thinking about originally..
  13. nice rolli, I am looking at those benchmarks for 3DSMax rendering.. looks like i7 2600K or i5 2500K will be great
