Re: HPT372 on KR7A-133R (ATA133) on production server

[Etienne Lorrain]

  I have this exact motherboard, with CRUCIAL 256MB 184DIMM PC2100 NP CL2.5
 memory.
 You first have to patch your kernel like Andy Jeffries said to activate
 the RAID controller. Most of the distribution still did not do it,
 you probably have to compile your own kernel.

 For a long time, I have only been able to run it 100% CPU for one hour,
 no disk access, if I set the memory clock to 100/200 MHZ.

 I am currently experimenting running at 133/266 MHz with the two
 parameters "DDR DQS Input Delay" and "DDR DQS Output Delay" changed
 to manual and increased by 2.
 Their autodetection does not seem to work, I am not sure.
 It seems stable - no error noticed for the last few weeks.
 Note that 100/200 to 133/266 did not seem to increase the CPU speed
 a lot, my usual task takes 39 minutes 100% CPU in 133/266 and
 40 min in 100/200 mode.
 I am not on a production server, so your millage may vary.

  Just my €0.02,
  Etienne.
