How can my ASUS A7V8X be slower than my MSI KT3?

[SFMagnum]

Yes, it is slower and I am even using faster RAM. I don't understand.

With the MSI KT3: I was using an AMD 1800xp+/512mb Mushkin PC2100 RAM, and GF4 ti4200

With the ASUS A7V8X: I am using the SAME CPU/512mb "CORSAIR XMS" PC3200 RAM/Same Videon card.

Now I realize the CPU and Video are the same; however, this Mobo has a faster FSB, it's newer, it was advertised and reviewed aas a VERY FAST board and the RAM I am using is also "faster" 2100 vs 3200".

In my 3Dmark2001se on the MSI I was getting 9950 scores.

In the same Benchmark on the ASUS I am only getting 9500 scores.

Now I realize that 500 marks isnt that much; however, I would think the ASUS with better RAM would blow the MSI away.

I am using the latest 1010 bios on the ASUS too.

I know that the 266 FSB on the 1800xp limits the ASUS board, but I would still think the ASUS would be faster with the faster RAM too.

Any ideas? I mean I have read how FAST this board was all over these forums so I got one...but its slower than my MSI all things being failry equal so what gives??

it runs faster with the FSB and Memory timings in Sync.

Or you can run the bus at 166 and reduce the multiplier on the 1800+ assuming you unlocked it

just as a random question, if you run the memory at a higher speed than the FSB (ie: Ram at 400, FSB at 333) would you see a preformance drop compared to running them both at 333?

I would assume not, but I'm not sure.

Hmm, I'm still kinda confused. My questions were not really answered. Any suggestions from someone who might have or has had the same set up?

I am no expert but I have been told that if you run the Processor and memory at same speed you get better performance. If they are not there is a performance drop. check the article at www.cpuplanet.com about memory

Once we started testing the A7V8X we started to see that, for the most part, the motherboard lived up to our expectations. However, clearly DDR400 performance isn't all that exciting; in fact, it falls behind its own DDR333 performance numbers in addition to other DDR333-powered boards. VIA's P4PB 400 (P4X400) Pentium 4 motherboard suffers from the same issues.
