OC - Xeon SL74T 2.4ghz advice

hi all

im a total noob at overclocking but i know the basics, just not had the experience.

I have a server type machine:
Asus NCCH-DL
Intel Xeon SL74T 2.4ghz (x2)
2 Thermaltake HSF's
1GB DDR400 Geil Value Ram

Xeon Spec
http://www.cpu-world.com/sspec/SL/SL74T.html

I want to OC the xeons to see what I can get out of them without killing them

They are currently running 133x18 to get the 2.4ghz. they did boot at 166x18 when i first put them in and it worked okay lol, but i soon lowered so i dont kill them.

what do you think is a reasonable overclock for them?

I have a pentium 4 3ghz (HT) machine and was considering replacing it with these xeons.

thanks all, any advice would be cool

cheers

i was about to start overclocking, upped the fsb by 10 and got a BSOD :confused:

... rebooted and a config file in windows was damaged so im gonna have to reformat...

stupid machine lol.

it needed reformatting anyway

what kind of cooling did you have on them?

Nucleo · 12 Apr 2006 at 18:33

the only voltage changed i can make are to the chipset vcore and dram vcore.

seems to be a bit dodgey booting up, getting an overclock boot fail error at post,

'f1 to continue or del to enter setup'

core voltage on both cpu's is at about 1.27~1.29

at the moment running @ 166x18 for 2.98ghz.

gonna run some superPI to make sure it is stable and check temps

gah, this is doing my nut in.

I set it to 166x18 get into windows, check cpuz and it has dropped the clock back to 133x18, resulting in 2.39ghz.

and how would i raise the cpu voltage on this board?

Nucleo · 19 Apr 2006 at 23:00

right

did the U-wire mod, took longer than 20 mins because im butter fingers

only did the 2 wires to see how it is, boots @ 3.0ghz with ease now.

I know why it wouldn't boot before, but i wont say because the reason is so nooby lol
(the jumper was set to 166, had to change it to 166 it seems i can change the fsb by using the jumpers, but the editing in the bios does nothing?... i can change the multiplier in the bios, but the alterations to fsb do nothing)

ran superPI, 2 instances for both cpu's and all is well, new volts rewgistered and temps @ 40c

what kind of temps are too high?
what kind of speeds should i expect?
