Athlon Xp 2100 and Crucial PC3200

[horatiub]

Hey guys! I have a question for you:

I currently have an Athlon XP 2100 CPU with the Asus A7N8X motherboard and 1GB(2x512) PC3200 Crucial RAM DDR 400. When the system boots up, it shows that my memory frequency it's set at 133MHZ instead of 200 MHZ that it should be for PC3200. I even ran some software and it was showing the same thing. I know that XP 2100 has a FSB of 266MHZ, 133 on each channel, so I was wondering it that's got something to do with my memory running at 133MHZ.

Any suggestions?

Thank you

Your motherboard is running the memory 1:1, which means it is running it at the same speed as yoru FSB. It might be possible to go into the bios and select a divider that'll let you run the memory at its proper speed. It would have to be a 2:3 (FSB:MEM) divider for the memory to run at 200mhz (pc3200 speeds).

Another thing you could consider doing is raising your FSB up to 200 mhz, but to do that and keep your CPU stable you'd have to lower your multplier. I don't know how fast yoru CPU runs, so I dont' knwo what multiplier you'd need, but to find out divide your CPU's speed by 200 (yoru new FSB). Just make sure your board can support a 200mhz FSB first.

yeah, the board does support the 200mhz FSB

The A7N8X supports 200mhz fsb, at least mine does. It's a Rev 2 board.

I think it's because of the CPU, mine it's a Athlon XP Palomino FSB 266

That sounds like you have the right answer. Palominos were 266 FSB and I dont think anyone managed to get anywhere near 400mhz fsb even with unlocking the multipliers.

Looks like your pc3200 will run at pc2100 speeds until you get a processor that uses that FSB or overclocks to such speeds.
