WHICH MB AND CPU?

here's what i'm talking about:

Do I need the same size RAM sticks to run in Dual Channel? Yes (AMD at this point says yes)/No (Intel) but you do usually want the same speed and latency as every thing clocks down to the slowest of both. Example 533Mhz CL4 mixed with 667Mhz CL5 will go with the slowest of both 533Mhz CL5 (not always with the latency) and slower than if either were matched. Same size sticks will run slightly faster symmetric RAM array (Interleaved). If the RAM is of different sizes it runs in what is called “asymmetric RAM array” (Intel Flex Memory/ AMD does not support). The greater the disparity between your 2 sticks the greater the performance hit vs sticks of the same size. The difference seems to be approximately in proportion to the ratio of the the smaller stick x2 to the entire amount of RAM. An example with Intel, 1GB stick and 2GB stick. 2/3, 1GB(smallest stick)x2 to 3GB(the entire amount). Well 2/3 of the total improvement, of the Dual Channel running with the same size sticks (symmetric RAM array) 10%, the asymmetric RAM array example is about 6.7% so a 3.3% less than symmetric RAM array. With 512MB stick and 2GB stick, 512MB(smallest stick)x2 to 2.5GB(the entire amount). 1/2.5 4% improvement. AMD's will show greater improvements and losses, Dual/Single keep that in mind.

so, it WILL work, but not 100% efficiently as it should. that's why they sell hi-performance gaming ram in pairs, ie - they are EXACTLY THE SAME.

hope that clears it up now.

Think i see what you are saying but what i am saying is the 2 1gigs are paired and the 2 512's are paired so it is not linking a 512 with a 1gig for instance.

I agree better to keep same speed and timings.
 
Pretty easy after i worked out that the E5200 was not starting at 333 fsb (would not boot at 400 duh) but anyway 1.45v and 320*12.5 easy easy, temps high sixties under prime95 both cores

um, he's running an nVidia card, what if he wants to sli in future?

agreed on the nvidia sucks part though :D :D :D

gfx card is old, may upgrade at later date. ati or nvidia doesn't matter . although mb chipset is currently intel which i prefer anyway.
asus mb and cpu suggestions are noted. will look into prices.

thanks all.
 
one last question.
major difference bet. p5q with epu6 and p5q deluxe? price differential is huge!

The main difference is that the P5Q Delux has 3 x PCI-E x16 slots (2 x 2.0 and 1 x 1.0) and so supports CrossfireX.

Other than that, has a copper heatsink, different onboard audio with optical out, supports an extra (E-)SATA drive, has dual Gigabit LAN and an onboard on/off switch.
 
so if crossfire is not important to me, the p5q would be fine?
seen pics of these boards. the orientation of the ram slots bothers me. seems to be at right angles to the pcie slot. is there enough space for the huge gfx cards (esp. nvidia)
nowadays?

P5Q would be perfect.

Won't be any problems with the RAM - I just built a 9800GTX+ onto a P5Q and trust me, that card is huge! :p
