Can't USE XEON / NOT RELIABLE

[reza]

please update your motherboard bios...the 1 youre using is an old version.
good luck

[ezrhythm]

ok, thats a promising solution thanks...

[Randy]

make sure your ram is registered too, without registered ram, your xeon will crash.

Many 3dsmax prepasses are done with only 1 thread. By disabling the HT, you'll have 1 processor working on it instead of 50% of one only (with a dual system). Sorry for the quick&dirty example, but that's almost the case.

This is not true, what you see is'nt what you get. The taskmanager is showing 25% cpu usage with one thread and HT enabled, but this does'nt mean that the thread is using only 50% from a physical cpu. The performance will drop only about 10% (max) compared to disabled HT. CPU 0 & 1 are physical cpu's, cpu 2 & 3 are logical (HT). So disabling HT is no solution, because the system performance will suffer, winXP is optimized for HT. A better way is to disable the HT sometimes for the application only (by setting the cpu affinity in your taskmanager). Just disable CPU 2 & 3 for max to find the best performance.

i guess there is no temp-issue, the intel board is using the thermal throttling feature, if the temperature is too high, your chipset can adjust the CPU speed downward (without any message ;( )
btw: the 2,8 is a prestonia core, not a prescott.

I would still be inclined to check it tho.

EIther way something is wrong, and so far we dont know what it is. Could be anything.

Im just going by what i have seen before, alot of these problems come back to a heat issue. Its easy enought to check.

[Randy]

sure, if the heatsink is'nt fitted 100% exaclty, the chip can't throttle fast enough downward and a good cooling is basic for a stable system. maybe you can try to lower the cpu multiplicator for testing.
but please check your ram (specs) and casetemp before that.

Temperature is OK... i was trying to flash my BIOS for 2 hours... i cant boot up in NON-HIMEM environemnt..whatever it is. I booted with different boot disks, same thing. Phoenix Flash utility complains that i got HIMEM on, there is no way i can switch it off. bloody hell, this is tiring

Here is the link.

If someone got the same mamma and flashed it somehow, please help me! I got the oldest bios on this one, there were loads of bug fixes since.

[reza]

you need to create a boot disk by formating the floppy disk using dos 6.2 or windows 98 or me

at dos promt in dos: type format a:/s or using win98 go to add/remove program and click create boot or start up disk then unzip the bios to the disk...

ill get more info for you soon..

[ezrhythm]

thanks, but as i said, i've made: 98 Bottable disk, WinXP botable disk, DOs 6.2...windows ME boot disk. Non of them r working properly. I still get error regarding that i should run DOS in non-himem environment.

[Randy]

use drdos to format the disk, dos 6.22 will not work with phoenix bios (often).
ftp://ftp.abit.com.tw/pub/download/u...s/drdflash.exe
insert a floppy and start the drdos for bios flashing.

[ezrhythm]

it worked! thanks!!!

[reza]

no problem..

i suggest you post your findings so that others would benefit from it.

Having problems with HT on ourselfs, we also would like to know what you did to make it work.

Erik

[reza]

have you tried updating your bios....i did and updated my windows xp..
ht does not work with older version of windows 2000

[Erik de Graaf]

We have windows xp pro.

So all you did was update your bios and windows xp and it worked ?
