Sometimes we have to pay lot to get hard to get parts and this is one of these case you have to accept that and get terminator RIMM.

Cheers,

Oh, as stated above I did purchase the RDRAM Terminator Module.
It is just that the error code is now different, for other reason.

Cheers

One of the 3 pin fan headers on the board is designated for the 'PCI Area' - most probably it's either not connected or not in spec.

Thank you very much!
I do not own the original case. So it is a definitely "not connected" situation.
I guess I could try tricking it by connecting other fan in that header and see what happens (trial and error).

Get PWM fan you have in parts and try it in any fan header till you get no error? Then hunt down 3 wire fan later on. The PWM fans has correct pinout plus 4th wire for PWM control to adjust rpm but not used since the first 3 pins are same as 3 pin fans. The 3rd wire is tach signal to let motherboard know how much rpm the fan is spinning at.

I corrected my previous post to attach the correct TechRef manual, now Series 1 (Slot 1) rather than Series 2 (Skt 370)

Terrific!! Thanks again!

I got the same board without any RAM and can confirm it runs with 2xRIMM und 1xCRIMM.

The CTRIMM module is not required.

I got fed up (with it not working) and gave it away to a mate.
Judging by your comment, probably there was another issue with mine then.

The information you supplied will help others in the same situation.
Thank you!

Testing my retail boxed P3C-D board I can also confirm this.

My observations:
- It NEEDS a C-RIMM module in the 3rd slot nearest to the AGP port, it wont POST without it, or with a memory module instead. Therefor it wont boot with 3 modules.
- Does not need CT-RIMM, any cheap OEM C-RIMM like Dell ones will do.
- It NEEDS a C-P2T PC133 Slot 1 terminator module in the second cpu slot if only 1 CPU is present, otherwise it wont boot. With a pair of same speed processors that work in dual mde the terminator isnt needed.
- With a 1999.12.3 dated BIOS memory modules ar capped to 64/128MB 600/700/800MHz parts. It will not boot with 256/512MB modules.
mod: BIOS is first release ver 1009. It also has a 866MHz processor, and a 8x multiplier limit, and will not reboot with a 850mhz PIII installed. On first boot it detects it as an 866MHz part but will black screen on reboot whatever settings are selected. Interestingly enough it will happily run a 1000Mhz Slot 1 Coppermine with 133MHz FSB, after upping it from 100MHz on first boot. It does complain about BIOS update data being incorrect on CPUID 00000686, hidden above PCI device listing, but nothing more.

Don't jump to too quick conclusion regarding the CT-RIMM. The reason for the third slot was (obviously) to allow use of three RIMMs. Unfortunately Intel couldn't get the signals stable enough with three RIMMs so instead you need to shorten the signal paths with that CT-RIMM. If you don't they stay as long as before Caminogate and you risk subtle RAM instability.

Im just glad my mainboard booted at all. 😀 Seeing your posts with your numerous attempts at obtaining a working P3C-D board, i feared i had a paperweight in the Asus retail box that included a proper CPU terminator but not a Rambus one. I too came across potentially dead XM600 boards that popped up here and there. They were always "not tested" or pulled from a working system but years ago, so came without any warranty.

A friend of mine is currently considering to buy a still working XM600 workstation. With this in mind im not sure thats a great idea.

If it's working, it's working, and with a CT-RIMM it should be fully reliable.

My actually working P3C-D is completely unproblematic. I have two PC800 512MB RIMMs and a CT-RIMM in it. i820 is pretty niche, and an early pre-Caminogate board with 3 RIMM slots more so, so if that friend wants something simple that 'just works', it might not be the best choice. But if he's into oddball stuff (as I am), this fits the bill perfectly.

Greetings,

Curious if anyone has a case or at least the front panel they wish to part with? I have an Awin A500 which the front panel may fit, may need some fine tuning. Ended up with one of these boards, awaiting some parts to give it a whirl. I have the HP 1.13 board. This is a good thread to reference along with the other P3C-D HP-XM600 threads.

Also, if anyone else has this board and wants to test it with the front panel, I think the front panel part number is 5064-9162
