Possible to test RAM speed support?

[neo]

Since my computer will not boot up at a 133MHZ FSB, I propose this method of testing to see if it is the RAM that is holding me back. I have Crucial PC133 RAM, and when I set my PII 400 at 4x133 the computer will not even POST. Perhaps if I lowered the multiplier clock I could test the RAM without overclocking my CPU. Correct me if I'm wrong, but isn't it possible to lower the mult. clock, but not make it any higher? If it is I might set the MB at 3x133=400 to see if the RAM can handle it, right? That way I can remove the CPU, L1, L2 chaches from the equation. Is this a possibility? http://www.sysopt.com/forum/smile.gif :0

If you have PC133 RAM from Crucial, this RAM is designed to run at 133 MHz, the problem is not your RAM but it could be a number of things, your motherboard might not be stable at 133 MHz, just because they offer that speed doesn't mean it will work (Abit boards have 133 FSB option, buy none of the hardware sites that have done reviews on them have been able to get an Abit board to run at 133) it could be your hard drive or one of your PCI cards, unless you are using an Asus board, at 133 on their boards the PCI bus is 33 MHz. All of the PII 400's are multiplier locked (to the best of my knowledge) meaning you can't change the the multiplier (up or down) and last but certainly not least it could be your CPU.

Nope, multiplir lcoked, Intel though of us setting the FSB to 133 on a 350mhz system that would not go to 465, and going to 400. Or a 400 that will oviosly not post at 532 without supercooling, setting it to 133x3.5 and presto, 465mhz! Also, they are always talking about how important the higher FSB is for RAM, you could simply set the CPU for 133x3 and going to the same 400 (399 actualy), and having faster ram. They made this mistake for some of the orriginal .35 micron CPUs, I had my 300 running at 300, but with faster ram.

Well from your statement LJE2, I discern that it is, in fact, my CPU. Heres the lowdown: I have an ASUS P2B-F, supports FSB/PCI=133/33. When I do try to set it at this choice it will not post still. Therefore it is my contention that I can rule out the HD, and all the cards. Also, my RAM is rated at PC133, so I can rule that out. Talked to Crucial today and they said they can almost guarantee their ram is up to spec. The only obvious choice is my CPU. I will try to disable the L1 and L2 caches, to see if they might be causing the rucus. BTW, I do have the VEK12 --->running at MAX (100% CPU) 38 degrees C. I don't think temp is too big an issue. I'll keep you posted (no pun intended)
