What Memory Bus Speed I have ?

Mir96TA · May 24, 2005, 03:45 AM

First of all; I would like to say : hello, I am newbie Here

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.

So got him an Asus P4P800-VM MB
Upon my diagnostic I found out; his ECS MB is GOOD

; 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.

Welcome to the forum.

Yes the real frequency is 200MHz and any utility meant to display the frequency should report that. If the same utility reports both variations on similar systems then there's simply some flaw in the software. And 3DMark isn't primarily a system information tool, but the information is rather a side feature. The figure 800 is used to reflect the QuadDataRate feature just as you say, and as with DoubleDataRate the actual frequency is not affected by the fact that the technology can send data four or two times each clock cycle in ideal circumstances. Just something I feel it's best to mention whenever the topic comes up.

First; Thanks

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 Tiled Mode ?

I believe Tiled is when you place over two (3+) sticks of RAM in the PC which would mean it couldn't run the extra stick as Dual-Channel or Linear.

IE, two sticks are set to Dual-Channel while the other one is "alone" so is Tiled with the others.. I think. Anyone care to double-check?
