Server board help needed

Re: Server board help needed

There are a lot of P4 boards that suffer with a design flaw that goes back to a mistake in Intel's reference boards.
The voltage regulators for the RAM slots or Chipset [Memory Controller] can't handle the load of 4 sticks of RAM and keep the voltage stable.
[Not the regulators for power, I think it's for Vtt.]

What Rat is rattling on about is the cheesy fix Asus [and a few others] came up with to avoid having to fix Intel's mistake on their production boards.
- Except that it doesn't have a damned thing to do with the BIOS.

With all the trouble I'm having, I remember why I switched to AMD after upgrading from my Pentium 166...

Socket 775 is nice in some ways, but I don't think I've ever seen anything so hit and miss.

I'm going to play around with it this weekend and see what I find. This is all getting really discouraging though.

Got it to POST with all 4 gigs installed, after updating the BIOS and replacing the faulty test CPU I was using. I should have tossed that chip after the first time it flaked out on me.

Now I just have to wait for the real CPU to come in, and I can get on with the project.

no it's not, that prefix is a 32bit athlon board using a via chipset.
i'v got one - i suspect it's more to do with the capacitance of the tracks between the sockets.

Re: Server board help needed

The Athlon boards use the same reference design in so far as the RAM regulators go.
In fact AMD basically plagiarizes Intel's reference designs in a lot of areas.
VRM, PSU Guidelines, AGP VR.
- Don't believe me, go look up a few.

No, it's not the capacitance in the traces.
Good idea,, but not it.

I'll see if I can find one of those long drawn out explanations if I have time tomorrow.
70 miuntes to midnight here. Time to go party some more.
