Old technicality for p4 socket 478...

[Mavhenz]

(!SEE BELOW FOR A NEW QUESTION!)



Hi!

My question might be stupid, but I'm asking anyways since I know that you are:

Kind


I got a P4 socket 478 (I know this is old, but for me it's a test field). I got a northwood that I have push from 3.2 to 3.680 ghz. I got corsair ddr 400 XMS 2-2-2-5 that I currently running at 2-3-3-5 due to complete use of memory slot. And I have a p4p800 se motherboard.

If I switch for a 2.8ghz/1m/533 might I got trouble? Will I have imcompatibility issue with my memory that run at ddr 400? Will I got beter result with a p4 3.0 ghz/1m/800 ?

Will I have trouble by switching from 800 bus speed to 533? Is that compatible with my ddr 400 memory?

Might I be able to do better overclocking? At the moment I got a fsb of 920.

Thx for

Lol same setup i had when i first joined this forum.

Id stick with the 800mhz fsb 3.0

My setup was p4p800 SE, 2.8 Prescott, 2 gigs xms 400 2-2-2-5

Note though after overclocking for a year or so the board fried

And how far did you go?

I mean for the CPU Oc?



PS: You might not have the ''cooling'' that I have...

cnps 9500 zalman cpu cooler
2X80mm mem cooler
Nexus Nhp-2200 Northbridge cooler

I just name that to keep it simple..

Hi again!

I have buyed for a really cheap price a p4 3 ghz prescott just for fun.

I have Everest ultimate edition and I do stability test on it.

My question:

What is cpu throttling?
I tried to find any documentation and it doesn't clearly respond to my question.
Each time that the temp of my cpu reach 55 or more, the green bar turn red and it start going higher and higher...
A graph turning from green to red is usualy not good...

I have tried to desactivate the tm1 tm2 and any power saving device in the bios. Still got the trouble.

Any suggestion?

When the core temperature of the processor climbs into the danger zone as defined by Intel, the processor is throttled down, that is it runs slower automagically to help it generate less heat.

Thx for your answer!

I tried to deactivate internal thermal control on the bios and any power saving device. I still got the trouble. Could it be a deactivate device?

I never breach the 57 degree (could it be too high?) for the core.
I am on air cooling, and I have never been over 1.6 volts. I know this is high but I won't go further....


If you got any advice to deactivate this thing, got ahead!

Thx!

From everything I've read on the P4 thermal throttling is that it's part of the CPU die & not in the bios at all.
In other words, it's part of the CPU & can't be turned off.
The only thing you can do to keep it from turning on is keeping the temp below the trigger point at which it turns thermal throttling on.
