what is holding me back
P IV 2.4c @3Ghz (Sl6WF Malay)
Corsair pc 3700 @ 250
Fsb 250 (1:1)
Hercules 9800 np @ 420/375
Maxtor sata 120 GB
Asus p4c 800 e deluxe (last bios update)
chieftec 360 watt
I can 't overclock further, when I set fsb at 265 I receive errors with prime95 (rounding was expected less than 0.5 or something)
When I set my FSB to 270 the message ' irql not less or equal' appear and a memory dump starts.
I've tried 3:2 and 5:4 but no succes.
My temps stay under 45°C (asus probe).
Can it be my powersupply? I have 5 casefans ( vantec tornado is for sale), 3 ccfls also.
probably not, my guess is your cpu won't go any further.
ram = ok as you have divided it (3:2, 5:4)
the best thin to find out whether your PSU is holding u back, is checking the voltages. Maybe upping the VCore will help (but not too high, P4's don't like that).
upping the vcore could put more strain on your psu, that's no way of checking the psu...
The VCore upping is to OC a bit further ;) .
Voltages are stable while stressing (prime 95).
I pushed vcore to 1.6V, i think it s high enough with stock cooling:).
I will test it again how far I can get my cpu, i thought the 2.4c was able to oc further :(
sometimes yes, maybe it'll be stable at 1.6 volts and 265 fsb, however I doubt your ram can take that 1:1
my P4 2.4C is stable at 3200mhz, anything higher requires a lot of extra vcore :/
Jmke how much voltage is given to your cpu?
At what FSB, ram frequency?
you know the FSB :)
ram frequency doesn't matter either
voltage: 1.65v @ 3.2
for higher I need 1.7+
