--------------------------------------

I currently have the 3.2ghz P4 overclocked 320 mhz and it runs 100% perfectly stable all the time. I have 4 256MB sticks of Kingston HyperX memory and its PC 4000 configed in bios by SPD. The heatsink I got is a Coolermaster Hyper 6 HSF with arctic silver 5 with plenty of case cooling and under full load the system never goes over around 34c and sits idle at about 21-24c with a pretty cool ambiant room temp.

Ok now heres my prob. I want to be able to overclock my system to 3.6ghz (Actually 3.7), but when I get to 3.6 the problems start. I'll up the FSB and it will run and boot at 3.6ghz. I run sisoft burn in and it will be fine with temps just slightly higher than they are now. Then I'll get out to play a game or maybe just open a app or click on something on my desktop and then blue screen. I'll reboot and then maybe it won't boot and I'll get a bluescreen. Then i'll reboot and it will be fine. Open internet explorer - Bluescreen, reboot, it will be fine, run burn in again...passes without a problem. AN on and on. When I get the blue screen is says something about win32.sys or sometimes IRQ_NOT_EQUAL_.....blah blah blah. I tries everything I know in the bios to maybe stop this. I should be able to hit 3.6 no problem with the cooling I have. I have the vcore on the cpu at 1.6 and I also have tried a slew of things, Like:

Disabling PAT
Turning memory voltage to 2.85 (or is it 1.85 I can't remeber)
Turning off memory turbo mode
Dropping mem from 400mhz to 320mhz

I don't know what could be causing me not to be able to overclock my 3.2 to 3.6? I should be able to go higher I think. Is it my memory, is it a bios setting I might be overlooking? This is really upsetting me because I know i should be able to get a better overclock. Anyway if anyone could help with advice on what to do to make me be able to overclock more I would appreciate. Thanks!

You might want to manually set the timings on your memory. I have Kingston hyperX pc-4000 memory and spd sometimes doesnt report it correctly.

Secondly you might want to try to run two sticks of memory only since there might be problems with running 4 sticks at once. my 2cents

Secondly , what are your v-core settings.

Is the AGP/PCI locked to 66/33

umm u hit the limit, tempramental are teh name of these little buggers. Sell it while you can and wiat for the price drops on 3.4s. I think I will pick one of those up and play with it when its affordable.

I have my vcore at 1.6volts. Actually I just hit 3.6ghz stable....well so far anyway. It passed prime95 and burn in and 1/2 hour of me playin doom III. I tried to manually set my memory timmings. It had it at 2.5-4-4-8 and the hyper x memory should be, according to specs, 3-4-4-8. So i manually set them to that and blue screen again. I then went in the bios and put the mem timings back to by SPD and then disable spread spectrum. After that its been fine so far at 3.6ghz. What is spread spectrum and could that setting have been holdinf be back? Ohh yeah I also do have my AGP locked at thse numbers posted.

 

[situman]

its not ur timings, with that speed, ur ram is running way below spec.

 

[lackdog]

Yeah i think my memory is running way below what it can handle too. I know heat isnt the issue either. Trying to see what I can do, thats why i posted at these forums! w00t!

 

[situman]

well i can definitely tell you its the cpu or you need a droop mod for your asus.

 

[lackdog]

Ok whats that..please elaborate more in your posts =)

 

[situman]

if you look at the voltage readings from CPUZ or MBM, you will notice that under load you vcore will "droop" or sag alot by as much as .1v so if ur vcore reads 1.55v at idle, you load vcore could fluctuate and be as low as 1.45v causing major instability.
