I was going off of what their User's Manual says.... I just looked at
their website, however, and in one place it says that it supports DDR400,
and in another place, it still says PC2700, so who knows :)
As far as the Nvidia drivers, it has always seemed to work on systems with
4 GB or less, as the mtrr problem doesn't show up until you start getting
over that 32 bit boundary. And, it gets worse, the more memory you have.
I have run on single processor Asus boards and an AMD SOLO board, and the
drivers fly. Unfortunately, on my TYAN system with 8 GB of memory, the X
server has always been very unstable, or just flat out didn't work. I just
got some new mtrr.c code on Friday afternoon that is supposed to fix this
problem, and I am waiting for the SUSE YOU server to update my system as we
speak, so I can build a kernel with the latest stuff, and then build one
with the new mtrr code....

Hi Kevin:
Thank you for responding.

Actually, the Tyan S2885 doesn't support DDR400 (PC3200) memory. It only
supports PC2700/PC2100/PC1600 DIMMS, so using the DDR400 could be a big
part of your problem.
My experiences would certainly seem to support that, but Tyan seems to
disagree. Please see the bottom of:
http://www.tyan.com/support/html/memory_s2885.html
Nonetheless, you may still be correct. Note that they only list two
recommended brands of DDR400, but 12 DDR333 makers. I would be very
curious
if *anyone* has gotten DDR400 to work in this motherboard.
I have had a TYAN S2885 board for several months now
(even a prerelease board), and the main problem I have had is with the
AGP
graphics. There is a lot of work going on to get the AGP graphics/Nvidia
drivers working correctly on this board, as far as BIOS updates to put
proper values in the MTRRs, new drivers, kernel patches, etc.. There is
a
kernel bug in the mtrr code that makes the system broken with over 4 GB
of
memory.
Ironically, the nvidia drivers seem tp work fine for me. Of course, I only
have 2GB or RAM. I didn't benchmark them but they sure *look* fast. gears
(at it's default window size) yields ~9375 FPS.

Hi,
I second the swap of memory to DDR333, if you look at a
couple
of tests that have been performed, the difference DDR333 to DDR400 is a
couple of percent depending on what benchmark. Can you try it with
DDR33 4x256MB Registered ECC, two in each processors memory slots? I
have this config(but 4x512MB), all PCI slots full supporting 2TB of
RAID5 and RAID10 storage and the system is rock solid. There are known
problems with older chip revisions handling DDR400 in the Opteron
Processor forums, usually on 244 veriants though.

I've got one going here and it's rock solid. AGP is a little
sluggish, but I'm working on that with Tyan and hope to
send a success
story/howto to the SuSE list at some time soon. I have had SATA
working briefly but am not using the onboard at the moment
(I have a
3ware 8506 SATA raid card instead).
Well, at least now I know it is possible.
My memory is 1GB ECC registered DDR333 directly from dallas memory,
and I've got 8GB installed with good results on my pair of 246s.
Interesting: you are using 246's but DDR333 memory? I am
using DDR400, which may be part of the problem. May I ask if
there was any technical reason for going with the 333Mhz parts?
Note that you MUST be using the suse -156 or later 2.4.21 kernel on
that board or there are huge problems. Start with that if
you're not
there yet and see how far that gets ya.
A good suggestion. I just downloaded & upgraded but alas it
made no difference. I am still suspicious of an
incompatability between this motherboard and memory. A
helpful soul in another forum posted this link which I found
interesting:
http://www.tomshardware.com/motherboard/20040112/index.html
Good luck!

Thanks - think I need it
