ProLiant 800 single PII 350 upgrade to dual PIII 600

[Ronald de Leeuw_1]

I have a Compaq ProLiant 800 which has a Pentium II 350 MHz processor, and I want to upgrade it to dual Pentium III 600MHz processors. The ROM is P18 11/08/2000. I already have the two new processors (Compaq part 153555-B21) with the VRM's. The first problem I had was that the jumpers settings for 600MHz processor speed are not printed on the system board. Using some binary logic I figured the settings should be:

SW1
1 off
2 on
3 on
4 on

When booting the server it gives the following error during POST:

Unsupported processor detected
System Halted!

Before I bought the new processors I did some research on the HP/Compaq website, and according to me they should be supported.
Or do I need a system board with a P14 ROM?

If you can give me the sps number of the system board, I can look up the data of how fast it can go and what the switch settings are.

Hello,

What do you mean by the SPS number, what format should it be?

I found the following on a label on the System/Processor Board (where the processors and DIMMs are):


313622 - 001 P138C0F25HDSLA 007918 - 101
007919 - 000 Assembled in Singapore REV 0F

And on another label:


*313663-001*

Thanks for your help,

313622-001 is the correct SPS part number of the system board. This board will take processors up to 650MHz, so the 600 is definitely supported.

With the 600MHz processor you have to use VRM part number 329267-001.

SW1
1 off
2 on
3 on
4 on

is correct for 600MHz.

SW2 should be off and off.

Well, I tried these switch settings, but no success. When I power on the system I get the following on screen:
.
COMPAQ System BIOS - P18 (11/08/2000)

.
Unsupported Processor Speed Selected.
- System Halted!
.
I the meantime I got two PIII 500 MHz processors, and they work perfectly in this system. But I still want to upgrade to dual PIII 600 processors, so I ran the System Erase Utility. And used the SmartStart 5.50 CD to configure the system. But after again plugging in the 600 MHz processors, I still get the error message stated above. Help!
