running 228fsb with mem at 320 giving me 3.2 ghz
timings:
DRAM CAS# latency : 2
DRAM RAS# precharge : 2
DRAM RAS# to CAS# delay : 2
DRAM precharge delay : 6
DRAM burst length : 4


prime stable for 10 minutes.
Load temps are 63°
After i stop prime it drops back to 44° in like 5 minutes
(looked back before submitting this post : 42°)

I'm using the "mixed mode" torture test, this is allright i guess.

Plz take a look at those mem timings and tell me they are correct.

The Senile Doctor

everything is perfect!!timings are ok, your ram is running securely there , well below its designed spec, you could try to make it run at 1:1 but it probably won't work and crash out on you...
you now have a 3.2 ghz that is faster then a 3.2 ghz standard because of the high bus, the low membus don't matter all that much anywayz
run a prime95 torture all night, if it stixx all night, then go 1 mhz up and run again, till it crashes out on you.

and now get casefans in there, and get another cpucooler

remember : a 3.2 ghz costs 700 euro's or sth

Question remains, how much below spec is my ram running?

Is CPU mhz more important than RAM speeds?

The Senile Doctor

the ram is running at 185 mhz now...
on a i865/turbo setting pure mhz speed is more important then ram speed...

you have to see what is the highest stable speed with the 320 divider you're using, check that first...
when you find the highest stable speed, rune a 3dmark run at that setting and note the result

THEN you can clock down and search for the highest stable overclock with a 1:1 setting (400 in dram configure), when you find that one (you'll have to lower your ram settings to cas 2.5 3-6-3 to check that) if you've found the highest stable overclock with ramspeed 1:1, then you 3dmark that one run, and just compare
i personally would opt for the highest cpuoverclock but that's just me :grin:

Finally got my casefans, and started pushing the limits.

Prime stable for at least half an hour (could go 3mhz on fsb higher before i got errors in the first 10 minutes). max temp 58°c

3402 mhz (243FSBx14)

screen :

The Senile Doctor

nice!
now you just need to run it an entire night folding@ home with prime95 combined. (that's 100% load for a hyperthreading cpu)
if it doesn't crash, it'll be stable 4 ever

nice result, that 3400 mhz powerbeast will last you quite some time!

Vidcard = GF4 Ti4600 ?
nice OC!

still on stock voltage I presume?

Nope, Geforce4ti4200 with 64mb (abit siluro)

http://service.futuremark.com/compare?2k1=7060735

all stock voltages.

Will run prime test tonite.
Is it dangerous if my cpu locks up and stays locked up for a few hours?

jmke

Never had any problems with a locked up system. Just turn of the power and reboot, lower the CPU speed or up the vcore and retry, but at 58°C I wouldn't play with that vcore

+the P4 has a build in temp sensor which will slow down the CPU when it gets overheated (+70-80%) to avoid damage to the CPU.

nice OC.. my P4 2.4C reaches 3.2Ghz at default voltage
