I am going to purchase an ASUS P5WDG2 WS Professional motherboard when they are released.

I was looking at the TYAN 2895 but the total cost of ownership was too high. This ASUS is like an enthusiast workstation board, I need it because I need to run 6 monitors 4 on PCI-Express bus & 2 PCI-X bus 66Mhz cards. I also will be running SCSI raid on PCI-X bus.

The purpose of this machine is to run charts in the financial markets. Usually this computer will be simply running a set of charts and peridocally I need to change the bank of charts to see another set of charts. I need it done fast hence raid and the video setup(vanilla PCI won't do).

Since the Ram and the CPU are capable, what is the effect of overclocking on PCI-X? THis is a new one for me

-Other issues and things-
I have Infineon Ram 2 Gigs dual channel (Got it for $100) which can overclock well it is rated at ddr2 533 4-4-4-12, can do ddr667 at 4-4-4-12 also but apparently can go to over ddr2 800 with the voltage raised. I also have an E6400 2 Duo CPU 2.13Ghz ready to put in it. (Got it cheap $295.00 after TAX)

Getting the memory and CPU at these cheap prices I could not resist. Running stock will probably do the job, but if I can tweak it for more performance then why not.


With a multiplier of 8, it seems that the E6400 uses ddr533 ram on a 1:1 ratio which makes it a "Perfect fit" However, it seems that oveclocking to ddr800 gives a natural ratio of 2:3 266*2=533, 266*3=800. In any event I should be able to go from 8*266 to 8*300 = 2.4Ghz = E6700



Thanks
