Could anybody tell something about direct relation between number of cores (X2 vs. X4) and it's influence on speed for virtualized systems as VMware, and ESX, and Hyper-V while using Athlon x62 X2 and Phenom II X2/ X3 /X4?
I have three AM2 mobos ASUS M2N32 Workstation Professional running because of their two PCI-X 64Bit-/ 133 MHz Slots with AMD Athlon 64 X2 6400+ BE on it - not overclocked yet - for getting experiences in virtualization and clustering for simulating High Availability and think about upgrading CPUs to Phenom II X4 - one out of these three: 945 or 955 (best choice?) or 965 - to stronger the host systems running in virtualization mode.
There are 8 GB Corsair DHX Twin2x2GB DDR2-6400 CL4 4-4-4-12 2T or DDR2-8500 CL5 5-5-5-18 2T on every board. Cooler is Skythe Orochi SCORC-1000. PSU is Corsair TX750.
I know I could take X4 940 BE because somebody tried it and found out that it works fine with BIOS V1801 instead of last BIOS V2001. But I want to be prepared and saving money with the CPUs if I have to change to AM3 mobos later what could be next step of investment.
Do you know any reason why I shouldn't take 9x5 instead of 9x0 and what the maximum for x (2, 4, 6) have to be? It's clear that HT (2000/1600) is the bottleneck of these mobo but don't care about this because can't substitute mobos at the moment. Any knowledge and/ or experiences with this kind of upgrading an use of virtualization?
Hi xaria. Thx answering. Surely you do mean the C3 Stepping with only 95W TDO (OPN Tray HDX945WFK4DGM / OPN PIB HDX945FBGIBOX) of AM3 socked 945. I agree but wanted also to known if anybody has some experiences in using and overclocking. Read that 945/ 955 have a barrier to be clocked over higher than 3.7-3.8 GHz at max. 1,5V?
