I want to switch to a current system. The system would look like: - ASUS M2N32 WS Professional NVIDIA nForce 590 SLI MCP North bridge NVIDIA C51XE South bridge NVIDIA MCP55PXE with NEC uPD720404 PCI-X for the old PCI-X cards - 2x1024MB Kingston ValueRAM DDR2 533MHz PC2-4300 CL4 ECC - AMD Athlon64 X2 3800+ EE 2000MHz 2x512kB 65W Box AM2 F2-Stepping - ATX be quiet!Titan BQT P6-pro-430 S2.2 (ATX & EATX) My question now has anyone experiences with the nforce 590 SLI MCP under dapper? Further on, has anyone experiences with the PCI-X, south and northbridge chipset? Is there any performance gain if I use 667/800 DDR2 ECC RAM? My server serves 3 OSes under it via VMware. ubuntu, as the host. 1x WinXP as guest for special windows server programs, and one additional "experimenting" linux. Usually ubuntu. I hope someone here can help me, because I have to switch urgently, due to the current system is now very unstable. Therefore the ECC RAM. best regards </BODY> </HTML>
