safe temp for 3000+ on neo4

[dimitris]

i have a neo4 platinum MSI and a a64 3000+ winchester

current overclock is 8x337 = 2700Mhz and is stable through prime, superpi, s&m

but LOAD TEMP after lots of hammering is 50 celsius.

cooled by thermalright xp-90

does anybody know if 50 degress is safe ? should i lower the freq to drop it a bit ?

50c is a little warm, but well within the thermal range for the processor. Try tweaking your case fans for better air flow, (positive air flow) to see if you can get the temp down a few degrees. Alot of times a case fan will rob the air stream from the cpu fan, thus raising temps.

eddie,

i am pretty sure my fans are positioned correctly .. i have 2 12cm fans in front one 8cm exhaust on top, the thermaltake silent cat 9 on top of the thermalright xp-90 and another 12cm exhaust on back end. Also a 9cm zalman silent on the side blowing cool air directly on the board and of course coolermaster's crossflow blowing cold air from the other side on the board. I can't see anyway to change these.

after 1 hour of s&m maximum degrees were 51 cpu and 38 system. Do you think these are all right ? Should I be worried let's say around 55 or so ?

55c is a little warm, but not dangerously so. You hit 60c, then you need to take action to get the temps down. I'd be more comfortable to have temps in the mid 40c range when oc'ing.

eddie, thanx...

could you help me with sth else ?

in order to overclock i first set my ldt and my cpu multiplier way down and then started to pump up fsb in order to see where my memory was completely stable. Results :

220 Mhz : 2-2-2-8
245Mhz : 2.5-2-2-8
268Mhz : 2.5-3-3-8
270Mhz : 2.5-4-4-8

Then I set everything down and started watching my CPU. I could get it to 2700Mhz with no errors and max 51 degrees.

and finally i was ready to setup my system. BUT while everything works normal with settings of 268 fsb, 9x multiplier (2412 cpu) 1:1 mem and 3x ldt ...

IF I set a divider in the bios everything gets screwed up. Other times it won't boot and needs reset .. other times it will boot .. using clockgen will sometimes lock my system but another time (same settings it won't) ...

is it possible that dividers don't work correctly on my system ? btw cpu-z correctly identifies divider when pc boots...
