PC700 and i840 motherboard?

[Kwad Guy]

I have an HP Kayak XU800, which is built on the Intel i840
chipset. I have read conflicting information about whether this
motherboard supports PC700 memory, and if it does, whether it
uses it in PC700 mode (doesn't drop it down to PC600)...

Does anyone know for sure? Also, does anyone know if you can mix
ECC and non-ECC memory? (Obviously, you need to match ECC characteristics
for the pairs). Some motherboards don't mind mixing memory (drop
down to non ECC for all memory), and some do.

I remember it dropped it down to PC600 speeds. PC700 was not officially supported. Never tried mixing ECC and non-ECC but I suspect this it will default to PC600 non-ECC. All the Kayaks we have use ECC PC800.

Just a scientific wildass guess on my part.

any reason you want that chipset?

I believe windogg is right. The board default pc700 to 600 non-ecc. Wether or not ecc is funtional i don't know.

Maybe because it's the best P3 chipset, and he already has it?

The i840 chipset is GREAT...It is super stable and very fast. 4x AGP
Pro. 2 64 bit PCI slots (5 slots total). On-board U160 SCSI (for
the Kayak implementation). About
the only bad thing I have to say about it is that you top out at
dual PIII 1Ghz processors and there's not likely to be anything
faster.

AND the Kayak XU800 (like all the HP Kayak computers) is really
well built. Nice case, well ENGINEERED venting (which means more than
putting a fan into the case and calling it a night), good styling,
excellent quality all-around. Overpriced at retail, but (IMHO) the
best designed and implemented branded workstations available.

The only reason I'm asking about PC700 is that I have several
of these and a bunch of PC700 memory...Figured that if they treat
PC700 at the "correct" PC700 speed, then I'd consoldiate the PC800
memory and populate one with PC700. But if it's gonna drop down
to PC600, then that's a waste...

Yes I have to agree with Kwad Guy. Say what you want about Rambus but anyone who has used a i840 based system will respect its stability. The HP Kayak XU800 is overpriced. Most of it has to be attributed to the fact its overengineered. At least you get great styling and a neat little backlit LCD screen. It actually dead silent like most HP business systems (Vectras and Brios). This is important when you might have several hundred PCs going all at once in a cubicle farm. Imagine 50, 100, 200, or even 500 Delta 7000RPMs. They are easy to work around since everything is either on a rail or snaps in. Would I pay for one? No way. Would I work with it? hell yea.
