Ok i have a p4 3.2c (CPUZ identifies it as steeping 9 ? also d1 showed)

Got ocz platinum pc 3200 in duel channel set at 2-2-3-5-8

I took it to 205 fsb and alls good.
dramm is at 2.7 atm. according to ocz i can go up to 2.8 without voiding warranty..

I would like to get to around 210-215 but i am wondering if something goes wrong will i have to open my tower and rset cmos ? i dread to have to do that lol.

Got very good airflow and a vantec cpu fan 4 or 5 k rpm with As5 on the chip . agp is locked. i think i once tried 210 and it locked, i dont remember if i had to reset cmos or not.

so at 205 fsb i am at like 3.28 or 3.29 gigs .. would like to take it to near 3400 if possible but dont want to shorten life off of anything. reccomendations.
 
Check your manual. Most boards have a key sequence at cold boot that will reset the bios to factory defaults or the CPU to default speeds. Well some do anyway. Its a great feature. Usually you have to cut the power supply off or unplug from the wall then press and hold down the key when you fire it back up..

You probally not going to get a lot higher unless you relax the ram timings a bit.

Good luck and have fun !
 
The 3.2C will go to 3.5 on air, easily. You could probably squeeze that with stock voltages, as well, so it does not heat the processor too much. It likely has 3.9 in it, but you would need better cooling to do so. As for the RAM, I had the same OCZ Plat DDR 3200 2-2-2-5 on my ASUS P4C800E dlx 875 at 250 FSB. You should be able to stick to the stock timing to around 210 or so. Go to 2-3-2-5 to around 220, then 2-3-3-5 to around 235, then 2-3-3-6 to 240, then 2.5-3-3-7 to go higher. Also, the SPD on some revs sets the VDimm at 2.6. This will work, but you will get a lot of errors with a mild overclock. the TCCD chips really like 2.75 V.
 
6-3-3-2 at 240? Highly unlikely that that is a normal scenario for any stick of RAM; no one sells PC4000 under CAS 3 except one or two brands that are CAS2.5 with 7-3-3, and that's just 10mhz higher than 240FSB. You can't pull 240 with even the extremely expensive XMS LL series 3200 at those ratings.
