Hi folks, I'm prepared to build a new server box for TESTING with following configuration; CPU AMD PHENOM II X4 940 HDZ940XCGI CPU Motherboard ASUS M3N78-EM/AM2+ GF8300,M.ATX M/B http://www.newegg.com/Product/Produ... RAM DDR-2 1066 8G The new box shall be used as 64bit Linux server. There will be about 10 servers, mail and web, built on the same box running Xen as virtualization software. No graphic editing nor gaming. RAM Selection: OCZ OCZ2G10664GK GOLD DDR2 1066 4G Kit (2Gx2) OCZ OCZ2RPR10664GK DDR2 1066 4G Kit (2Gx2) OR Kingston Hyper-X DDR-2 1066MHz 4G Kit (2Gx2) OR G.Skill F28500CL5D4GBPK DDR2 1066 4G Kit (2Gx2) OR A-DATA DDR-2 1066+ Mhz 4G Kit (2Gx2) Could you please shed me some light on follows; 1) Does the motherboard match the CPU? Any other suggestion? 2) The motherboard has onboard video card. Would it exhaust CPU resource? 3) What will be your recommendation on RAM stick selection? TIA B.R. satimis

"Does the motherboard match the CPU?" The board supports the CPU, if that's what you're asking. "The motherboard has onboard video card. Would it exhaust CPU resource?" Maybe a little, but mostly it will use RAM. "What will be your recommendation on RAM stick selection?" The cheapest that fufills your requirements. It's a server, not a gamer.

Hi jam, Thanks for your advice. The mobo has AM2 socket which is for Phenom II X4 940 But I just found another problem; DDR2 1066 is supported by AM2+ CPU for one DIMM per channel:- ... due to AMD CPU limitation, DDR2 1066 memory module is supported by AM2+ CPU for one DIMM per channel only. Please keep this limitation in mind when you purchase your DDR2 1066 memory module. http://support.asus.com/faq/faq.asp... So I can only use 2 RAM slots on the mobo if running DDR 2 1066. The max RAM is only 4G. I need 8G RAM. Then I must go up 1 grade, 1600 Any advice? TIA B.R. satimis

"Any advice?" Choose a different CPU. Do you really need a quad? Or how about building an Intel system that doesn't have the RAM limitation problem?

Hi jam > "Choose a different CPU." For AMD Quad CPU? I think I have to postpone building this new box. > "Do you really need a quad?" That is a good question. I'm NOT aware any software written for "quad". "Dualcore" will satisfy me, at present many Open Source software written for "dualcore". However I already have dualcore PCs here. To build a new box I expect running Quadcore CPU rather than going backwards. Actually I need a fast CPU with clock speed >/= 3GHz > "building an Intel system that doesn't have the RAM limitation problem?" I have been looking at Intel i7. The price of Intel i7 having clock speed >/= to 3GHz is very expensive. Also I have been looking at Intel Xen, a true server CPU. They don't have clock speed >/= 3GHz. Beside the price of motherboard for Xeon is quite expensive. If not because of the clock speed and price on motherboard I already considered AMD Opteron (quad-core) Model 2350 I'm at dilemma.
