Overclocking P41.8A

[Nightingale]

Ok I have a P4 1.8A , P4PE mobo, and Corsair PC3500 ram. I want to optimize my overclock but I am feeling noobish right now so can anyone give me a hand on the cas settings, turbo mode, etc. I got my water cooling running and I have my 1.8 up to 2.6 and my cas is at 2336 regular mode and system at optimal and not turbo.

Make sure you have the memory ratio set as high as possible, probably 3:4 is the highest, but I don't have experience with that mobo or BIOS settings. Maybe that's the turbo setting? Download and use CPU-Z to check your memory speed. Regardless, you won't be running that RAM to it's fullest capacity, so try using tighter RAM timings (2,2,2,5 is the most aggressive).

yeah I have it running at 3:4 so I will try to adjust the cas to 2225 and see how that works. Also I turned everything to optimal and throttled down my FSB a tad because I found my Northbridge is overheating. My PC beeps when I do something stressful such as gaming but my CPU is around 32C and the highest I seen it was 36 with 1.65Volts(I had it up to 1.7 on accident because I forgot the P4PE seriously overvolts.) When I touch my northbrigde sink its hot to the touch so I need to get a good cooler or water block.

Sometimes, just removing the N/B heatsink and cleaning the goop off, then reinstalling with Arctic Silver will give you a few degrees drop in temp. Don't remember if that mobo has a passively cooled N/B sink or not, but if so, then screwing on a little cheap 40mm fan will help too.

yeah its a passive sink and right now I just put a couple of the old case fans to blow on it and my vid card. Anyhow my pc is constantly beeping when I load games but all my temps seem to be in check except maybe the northbridge. I am going to go ahead and put some cerimique on the NB and see if that helps any.

What sspec is your chip? And what stepping?

 

[Nightingale]

Its a revision B0 chip

The beeping is to do with volatge I think - not temps or anything. My old P4BE did the same thing when I upped the cpu voltage. I just unplugged the speaker in the end.

 

[Nightingale]

Yeah I read my manual and the beeps are for improper Frequency or high cpu temp so I just unplugged the speaker for the time as it was really annoying when I was playing video games.
