RAM Problem

So I noticed the other day while putting my desktop back together that for some reason my RAM is running at 166MHz instead of 200. I change it in my BIOS back to 200, and Windows won't load (but it gets through the BIOS stuff with no problem). I change it back to 166 and things are working dandy.

Today I take out each RAM stick individually and test it in each of the slots (I have two 256MB chips in dual channel and one 512MB). I get the same problem with each one and it always works when I set it to 166mhz no matter the RAM configuration is.

I know it used to run at 200mhz, but I don't know how long it's been this way. Also, I know it should be able to go at 200mhz since CPU-Z says all of my RAM is PC3200.

Any ideas?

How ya doing, buddy?

Judging by what you've said, I'm gonna assume that you're running an AMD and that you haven't screwed with overclocking.

Have you tried running memtest86+?

The symptoms seem like the RAM's timings or the CPU's clock speed or Vcore have been changed. Maybe double-check those settings, and have them set to their defaults or "Auto" settings.

How ya doing, buddy?

Everything should be set to automatic in my BIOS, though I do recall some of the voltages being changeable. The clock speed for the CPU is correct (2.08GHz for a XP 2800+ after multipliers and whatnot)).

The RAM timings also seems to not be able to be changed in my BIOS as even when I set it to manual I wasn't able to scroll over them to change them.

I'll try te memtest86+ tomorrow when I have a little more time.

Oh yeah, and no overclocking.

This thing is sticky, and I don't like it. I don't appreciate it.

So for some reason when it was set to Auto for the RAM settings it was put to 166mhz, I changed it to Speed or some setting like that and now it's running at 200mhz with no problems.

I am a dolphin, do you want me on your body?
