try this and let me know. run it for a couple of hours

will check back tomorrow to see how your doing.

Lee

just did a cpu burn in 10x and it maxed temp at 45'c and held with no problems using sandra

how long is that test ment to run for btw lol

:EDIT: my bad i really should read

ran most of the night, all fine and no problems stuck to 46'c

well you can stay at 240fsb and lower the vcore running the cpustab test each time for a couple of hours until it fails then raise it up to the last setting.

If you test the vcore settings first you will see how good the cpu is by how low the vcore can go. This should lower your temps a bit too.

you can try upping the vcore and see if you can get it to post at a higher fsb. but the mobo could be the resons it wont post any higher not the cpu vcore.

are you still looking at the swifty pelt cooler ?

yeah i will try raise the vcore by .5 and then try for 250fsb if not i will just start to lower the vcore.

yeah im still thinking of getting the swift pelter block but not straight away. will probably build the system then do it last

humm what mobo would you advise for p4 overclocking?

one way is to look at what overclocks well...
at Cpu Database by overclockers has a good listing of diffrent CPU's and what boards was used when they were overclocked...
i myself don't have a prescott CPU.. have a P4 2.8ghz on a Asus P4C800-E
curretnly FSB is at 257 /w OC of 3.6ghz..

cool thanks dude

almost the same as me. can you go any higher than 257 ? 253 is my limit but it's unstable.

I know it's not my ram as it's xms3200 cl2 and is running at stock speed.
It's not my cooling at i have a water cooled system with the original cascade block so all that is left is my board.

I dont have north bridge water called yet but i do have a danger den zchip ready.

I have had it running at 264 FSB but then my fans run at 100%...
my wife complains they are to loud...
because if I lower he CPU fan speed then it does crash...
I believe it has something to do with temperatures of voltage regulators...
I do have a Northbridge water block(DD).
I know the OC is not being limited by my ram.
I have Corsair TWINX 1024-4400 ram running 1:1...
I should be able to get my FSB up to 275 before I hit the limits of my ram...
that is my target...

The heater core is severally limiting the air intake. Having to raise my the fan speed to 100% attests to that.
The Fans aren’t loud (listed at <30db)but the air turbulence when it hits the heater core is what makes them loud.

I’m in the process of creating an external box to hold 2 heatercores #2-342 & pumps will give me a better O/C.
my thread on that started here
have to update it in the next cople days...

nice rig. well one of the things on my list is a northbridge block so i think thats whats next as its running about the same temp as my cpu

some think that water cooling the north bridge chipset(NB) is a waste of flow...
i didn't try to O/C my system with out the block on the NB so i don't have anything for comparison...
it is posible that i would be getting the same O/C without the WB on the NB.
so i'm not guarateeing a better O/C.
my 2¢

well it was my plan to do it any way. hay i guess i will find out lol
