...my question is why? I thought that throttle point is 75C? My CPU i P4 540J (3.2GHz) oc'ed to 4GHz with 1.6 vcore set in bios. I'm monitoring throttling with ThrottleWatch and it jumps up to ~50%. My temp. never goes above 60C. Plz help...

check your bios for the throttle temp setting.

Ther's smth. in bios but I turned it off and CPU still throttles.

Get a better cooler, so it doesnt get that high in the first place. 60C is a bit high.

The Gigabyte sensors are probably reading too low. I think thermal throttling starts at about 70 degrees.

Any Abit users can confirm that?

isn't 1.6 vcore way too high? My 560J runs at 4004mhz (14x286) at 1.3625 vcore bois which reports 1.4vcore idle and 1.32 vcore load.

My computer with a XP-90c is 32hours dual prime stable at that config.

560J = 3.6GHz, 3.6GHz @ 4GHz = 400MHz OC... my is 3.2GHz @ 4GHz = 800MHz OC. It's twice higher OC than yours. Still 1.6V is a bit high :P but I dont care. What I want to know is:

1. Does Abit AA8XE reads temps to low?
2. If not... why my CPU throttles at 60C?

Sorry, thought you had a Gigabyte mobo... but I guess that's your vid card. I have a AA8XE and it used to report higher temp than actual. The newest BIOS update fixed that problem though. Yes 1.6v is rather high. I don't know why you are throttling at 60 degrees other than you are getting an incorrect sensor reading or the high voltage is causing problems. Have you double checked to see if the heatsink is properly seated? How do you figure your 4 gig O/C is twice as high as his 4 gig O/C? Seems like you are both running the same speed. Maybe his is better since he's not thermal throttling.

RMA the chip. Ive seen a rash of people on the forum have thermal issues with the latest batch of Prescotts (including myself). If I were you I would send it back immediately

I did... everything is O.K. :/... I'm using Freezer7. I will put the stock heatsink back on and see if that helps.

Can you link me to some topics? Where their problems same as mine - throttling?

its nice to have high voltage but i dont think 1.6 is needed in ur case?? my 550 runs @ 4016 @ 1.44v reported and stock volt on bios.. and i think u shud care about voltage cuz more voltage = more heat..

Dont trust temps sensors as being correct, i have swapped same model motherboards using same cpu,case and cooling and one was 10c higher then the other.

You are def experiencing problems because you are trying to feed 1.6volts to that pressy. Honestly that really isn't smart at all.

Umm guys, according to the intel spec sheet there are 2 seperate temp diodes in the core of the CPU's. They are in different locations, and have no relationship with each other. One is for monitoring, the other is for thermal throttling and shutdown. You can not tell at what temp the cpu will throttle as the one that you can read (provided your board reads on die) has nothing to do with the thermal monitoring sensor that is in charge of throttling and shutdown.
