P4 B0's seem to run cooler than C1's

[John]

When I had my Epox i845D mobo in this rig, I noticed that the C1 stepping cpu's were running roughly 6+C hotter than a B0 stepping cpu @ 1.525v. Now that I have an E7205 mobo, I am seeing the same results. Has anone else noticed this?

 

[John]

I guess I am alone. :Q

Dont have a C1. If you send me one, I'll be glad to test it out for ya!

ill LYK in a few days!

i did read something somewhere that any c1 cpu with HT disabled runs 5*C hotter :Q

Wonder why disabled???? so pretty mcuh all c1s from 1.8 to 2.8ghz then would fall under this category???

Ok, I'll bite. What are you getting?

He is getting a c1 2.0a ghz oem chip!!!! He sure loves them A's.......1.6 to 1.8 to 2.0...I don't expect him to get another a again after this!!! Vegas should carry odds on Thugs buying habits...

I think he mentioned a 2.0

Intel has a price drop on Monday for 2.4 and above.

So I've heard. I've seen rumors of $159 Newegg 2.4B in March. Got my finger on the trigger.....

Well, I do see my C1 runs hotter under full load. Same temps on idle.

could you run some HT on/off temp tests for us?

p l e a s e ?

Does it matter that my 1.8a doesn't support HTT? Running CPUburn now with HTT enable in bios.

 

[THUGSROOK]

hmmm,
i guess it would need to an HT enabled cpu to run those tests.

thx anyways

 

[Jgtdragon]

Well, if you can help me find the hack to unlock this HTT with all P4 then I can test it.

 

[THUGSROOK]

so far there is no hack.

even intel themselves claimed HT is enabled/disbaled during the manufacturing process and cant be changed.

not sure how true that is tho

My b0 at work runns cooler than both my c1 do. From anywhere from 5*-10*c

Here's an article that does just that

Excellent article. It looks like 70ish is the temp to shy away from in order to avoid clock throttling.

I am trying to find a way to disable it in the AX4R+ bios, but I do not see an option.

Keep in mind that the C1's die is about 10% smaller.
