    memory to cpu matching

    I think I'm getting confused by all the numbers but I'v got an athlon XP 2100 and an asus A7N8X dlx board (rev. 1.04), and apparently 3200ddr isn't stable on this board. more to the point, the cpu has an fsb of 266 - how does this relate to the memory speed I choose to plug in? if 3200 is ruled out how about 2700 then? and I'v no idea how to be sure it'll all work nicely for me.cause worried of stability issues that this board may kick up...

    • malfunction's system
      • Motherboard:
      • Gigabyte G1.Sniper (with daft heatsinks and annoying Killer NIC)
      • CPU:
      • Xeon X5670 (6 core LGA 1366) @ 4.4GHz
      • Memory:
      • 48GB DDR3 1600 (6 * 8GB)
      • Storage:
      • 1TB 840 Evo + 1TB 850 Evo
      • Graphics card(s):
      • 290X
      • PSU:
      • Antec True Power New 750W
      • Case:
      • Cooltek W2
      • Operating System:
      • Windows 10
      • Monitor(s):
      • Dell U2715H
    PC2100 = 266MHz
    PC2700 = 333MHz
    PC3200 = 400MHz

    But you can easily use a faster stick at slower speeds. Just make sure that the FSB / RAM ratio is 100% in the BIOS. Also - assuming the XP is a tbred b - you ought to be able to overclock it a fair bit anyway.

    its not an overclockable one ...
    does that mean I have to stick with 266memory or do I just play with the bios memory multipliers

    Unless you can increase the FSB there's no point in running the memory faster - the CPU can't use anymore bandwidth so no point. It's only useful if you were using onboard GFX or something like that. What do you mean by you can't overclock it?

    Is it just a bad clocker?

    Or is it multiplier locked?

    As if it's a bad clocker but unlocked you can always lower the multiplier and increase the FSB but keep the MHz the same... Or if it's multiplier locked but a good clocker (or even an OK one) you can raise the FSB (and the vcore) to raise the FSB and the total MHz
