CPU and DRAM frequency?

[drdan]

I just bought another computer. This is the Amptron K7-810LM motherboard and the Athlon 1.2Ghz processor. This is supposed to have a 200FSB. The CPU and DRAM frequency are both set to 100mhz with a 12x multiplier. I have an identical system (I think) with a 1.2 Athlon and a PC Chips M810LMR board which I thought was the same board. It is set to 133mhz for CPU and DRAM with 9x multiplier.

Does this mean that my RAM is only working at 100mhz (it is PC133) and can this be changed to 133mhz with 9x multiplier llike my other system or does that have something to do with the 200mhz front side bus (instead of 266FSB). I am pretty ignornt and don't completely understand most of the terms I just wrote about.

the terms 200/266 refer to the FSB being doublepumped, so yes it's runing at 200 ( if it's set to 100 in the BIOS ) and yes it's running 266 ( ditto ). To verify this get this program -Wcpuid (http://hp.vector.co.jp/authors/VA002374/src/download.html) it'll tell you not only yor FSB speed, but also your true CPU speed, your true Memory speed and give you details about your chisets.

I did some more research and these are not exactly the same board. The PC Chips M810LMR is 200/266FSB but the Amptron K7-810LM is apparently only 200FSB. Does this mean that the CPU and DRAM frequency must be set at 100 for the 200FSB motherboard? Does this mean that though I have PC133 Ram it is actually only working as if it were PC100?

Yep, that is what it means...any way the difference shouldn't be that noticeable...it would kind of be like running your car at 63mph instead of 65 on the freeway (you might notice it in really large spreadsheets or a slightly lower frame rate in some games, but normal everyday useage..no)...also some boards for AMD chips (not sure of the boards or the chipsets) allow for running the memory at 133 (a setting of FSB +33), while keeping the rest of the bus at 100, so check your BIOS settings. Basically what it all boils down to is that the board doesn't support a 1/4 multiplier for the FSB so that the PCI bus would run at the proper speed...
