100MHz vs 133MHz memory at 133 FSB

[Funkbird]

I recently upgraded from a P3 750Mhz @ 100MHz FSB to a P3 933Mhz @ 133Mhz FSB for a very good price, and am now faced with a interesting situation.

I have a ASUS CUV4X motherboard with 2 Mushkin 256MB 100Mhz CAS2 SDRAM modules for a total of 512MB of RAM. To replace this memory with Mushkin or Crucial 512MB 133MHz CAS2 or CAS3 will cost between $650 to $700 today. My memory currently works at 100MHz CAS2 with a 3/4 divider for memory, but I am unable to post at 1/1 ratio even with CAS3 settings. I am not too interested in overclocking as I have a unique situation with this machine in that it needs to remain in a closed, poorly ventilated desk and still run reliability, so the heat produced when overclocked is not acceptable.

I have read countless articles about the speed increases from the 100 to 133 FSB, but have not been able to find any type of benchmarks when taking a 133 FSB proc and using 100MHz vs. 133MHz memory speeds. I'm sure there would be some sort of overall speed increase between the two speeds, but how much in real world applications and games? I'm not too interested in dropping $700 for 133MHz memory now for a slight perfomance improvement and in 3 months be able to drop $800 for a new motherboard and DDR memory with much better performance.

Thought? Benchmarks? Suggestions?

Thanks

i AM IN THE PROCESS OF OVERCLOCKING A NEW 550E.I DISCOVERED MY OLD PC 100 MEM WORKKS FINE AT CA3 UP TO 124 MEG.iN THE ASYNCHRONOUS MODE .WAS THAT FAST ENUFF. HELL NO. SO I BOUGHT A NEW STICK OF PC133 HSDRAM (180 BUCKS.)IT CLOCKS OK UP TO 144 CAS3. AT CAS 2 IT DONT WORK. MY SUGGESTION TO U IS BUMP DOWN THE FSB ON A 1TO 1 BASIS TILL YOUR MEM. WORKS. THE CPU MAY NOT BE RUNNIN @ 933 BUT MEMORY BANDWITH PAST 100 MEG WILL MORE THAN MAKE UP FOR IT hOPE I HELPED MIKE ( BTW MY MB IS A CUV4X TOO!)

price is steep. although 33mhz more memory bandwidth would give a nice performance boost (up to 10 fps in Q3, maybe more in UT), 700 bucks is A LOT.

I'd stick to you're current set-up and wait for DDR solutions.

I'd think many would agree with me on that.

I have a Soyo SY-6BA+100, pIII 667, 256mb pc100, v5500 agp, 4 ata66 hd's (6,6,8,15). I have had numerous problems with this setup. First one would be the FSB vs. AGP. At 133FSB, the only choice on the Soyo for AGP is auto(88), 88, or 133. /1 and /1.5 or something. Everything runs fine at this speed, but when I run any game, guaranteed a crash within 2-5 minutes. If I put in my old v2, I can run all night. The only clues from readme's and soyo is to upgrade the ram to stablize the overclocked agp slot. Im eyein the Mushkin pc133 rev2. This can run at 2-2-2, and the 133 speed should help keep things stable.
Has anyone else had problems with 133FSB and the BX chipset limiting the AGP ratio? Ive also tried booting up as a 500 (100fsb 66agp), but it never makes it. Are the 133 cpu's locked in at 133mhz or higher? Has anyone had problems with the v5500 and oc'n?
HELP!!
