Re: [suse-amd64] SuSE 9.1 on MSI K8T Master-FAR SATA disk i/o problem

Kia Ora,

I have the same system a couple of problems I noticed with your setup.


1) Your power supply is far too weak... especially with 2 proc in you
need at LEAST 26Amps on the 12+ volt power rail. (I doubt you 360 watt
is anywhere near this). Use a Toppower 450Watt or Enermax PSU. 360W is
definitely too thin.

2) The OCZ ram you have will not work with this board. OCZ is designed
for Single proc performance level enthusiast boards, and has very
tweaked and high CAS timmings. This board is a server board, and does
not work well (at all...) with the OCZ pc3200 ecc reged ram. I made the
same mistake when first purchacing and got... many...many problems. I
have a number of threads open with OCZ/MSI/2cpu forums on this issue...
Scrap the OCZ ram. Get Samsung pc400 ecc ram. I did and I get MUCH MUCH
more stabler operation (samsung adheres to jdec standards and therefore
is cas 3 at pc3200 not cas 2 like corsair/mushkin/ocz)

3) The Raid on this MOBO is software only.... Disable all arrays through
the vt8xxx bios util (hit tab at startup). Then use Linux software raid
through yast to setup the array. I get Better performance using linux
software raid than I do from the Via windows driver designed by the
manufacturer... (I use 2 hitachi 160gbs drives, with raptors should
should get even better).


Hope this has been informative.

Kind regards

Joel
