P4 Memory Bus Speed with 800 FSB and PC3200 Mem

[Mir]

Second I am fixing my Brother's Computer. Here is what I got confused.
Here how it started. He said his MB died; he will ship me the computer and I can
replaced the MB and save his Data AKA Porn . I said ok no Bigge. I bough the MB
for TIME saving. :hmm: So got him an Asus P4P800-VM MB
Upon my diagnostic I found out; his ECS MB is GOOD :w00t:; His retail P4 prescott 3.2 is BAD
I crossed check with known Good CPU. Any rate it getting replaced.
He have 2 OCZ PC3200 512 a Modules. Running in a Dual Mode.
Mean while I installed my spare CPU which is P4 2.6 Gig 800FSB.
After installing every thing like OS and Benchmark programs; I have notice some thing real odd
3D mark see FSB as a 200MHZ FSB


Asus WebSite where they compare the MB its says it only supports 533/400


When you pull MB specification it says it can support 800/533/400.

I though may be 3D mark is goofy so I ran program on my computer.
Its says I am running 800 FSB

My Dell have 875Chipset; with PC3200 Memory/ P4 with 800FSB.

So guys I am so confused now. It making no sense.
I use think in P4 with 800FSB memory bus is quad-pumped. The real frequencies are 100/133/200 MHz; in actual data pahses.

No need to be confused, its not abnormal for manufacturers to have contradictory material.
Especially given the fact that with BIOS updates the capability of a particular motherboard will change.
Like you said 200 Mhz FSB is actually quad-pumped to have 800 Mhz.
And DDR memory is actually Doubled so 200 Mhz is refered to as DDR400.

Finally I say I will notice side by Side; so
I did the Remote Desk and run the Everst; I got shocked to notice
Bus Width is 64Bit on Asus :eek4:

Then I thought I migh have not installed the Memory in right Bank
so I confirmed the Memory Banks and Bios Post Screen
On Post screen it shows its running in Dual mode

and what hell is Tile Mode ?

Intel CPU is 800FSB because of the quad 4x200Mhz = 800Mhz. What ever you do with the intel memory , just time 4.

My system is 3Ghz ( 15x200Mhz = 3.0Ghz , 800FSB ), but I ran my RAM @ 250Mhz so the system now is running @3.75Ghz (15x250Mhz - 3.75Ghz, 1000FSB ). That's why if you want to run Intel, you need high speed memory in order to get the higher FSB.

I hope I don't confused you more.

That's not quite true. You can always use a memory divider to lower the speed of the memory in comparison to the Front Side Bus speed. You incur a small performance hit but it can be done very easily.

I dont want to do OverClock. Cause this Machine is Mission Critical Aka Porn Machine
My brother just want Max out what he have paid for it.
