Pentium 4 EE (ES) 3.4 Unstable at Stock speeds...

[ReTiCuLeX]

I got this off a trade, for my vapochill & prescott. I clocked it up at first, it rebooted my machine while gaming, so I set it at stock, and the comp froze, then rebooted =/. The voltages I can choose from are 1.6-2.0v for vcore, multiplier I can change. Anyone have a clue why it's doing this?

Well, are you sure it is at stock speeds and that the vcore is at 1.6? 1.6vcore should be plenty for a Pentium 4 to run at stock speeds.

An issue to look at is your CPu'd diode temperature. Perhaps you seated the cooling device on the CPU improperly or something got inside between them?

Please post all of your temperatures and your power supply voltages, on all rails. That information could definatly be helpfull to us in figureing out what is wrong.

There is also the possibility that the heatspreader is not flat or the heatsink/waterblock/whatever you have is also not flat.

You might also have a virus on your computer too, I got one where it would lock up and re-start.

+5 is @ 4.99, 3.3 is 3.264 +12 is 12.038, CPU temp 35C, 95F Case 28C, 82F this is all idle

Is the multiplier 17? Temps good? If your multi is 17, someone just ripped you.

 

[ReTiCuLeX]

It's unlocked, I can change the multi.

 

[@md0Cer]

Voltages look good, so do temps. Are you sure your multiplier is at 17 and this CPU is at stock speeds?

Are you sure it even is an EE 3.4? It had the proper code on the top of the chip? SOmeone definatly could have ripped you off.

Start setting the multiplier lower. Try booting at 2.8 Ghz and see if it is stable.

http://www.reticulex.com/p4ee.jpg This is a pic of when I got it and clocked it up. When I set it at stock, I have to set the multiplier, it doesn't set it. The guy claims it's a 3.4EE, and that it ran fine for him, so it "Should" run fine for me.

 

[@md0Cer]

Hmmm.......if you have to set the multiplier for it to go to stock speeds and default does not make it go to stock speeds, what does default make it go to? Whatever it goes to is probably most likely what type of CPU you have.

Now wait a sec.........I am no Intel expert....but I thought Intels are locked?

And if that screenie is what you had when you first got it and overclocked it, that means that it is stable when you overclock it but not when at stock? I am not sure if I follow you here.

It IS definatly possible to have a proc that is stable when overclocked and unstable at stock. My 3.0E D0 is living proof of that. It runs 100% stable at 250FSB and won't run at 200FSB. /shrug....I think it's my mobo, but I don't really care as long as my voltages aren't ramping. When the mobo goes, I'll just send it to Asus.

He has an ES chip, its unlocked.

 

[ReTiCuLeX]

Yep ES, well I just reseated my HSF, Reset CMOS as well. I bet it will still be unstable, at stock or overclocked.

 

[@md0Cer]

ooo ok I have to search ES chips....I am even out of this world on AMD's too now

Well, good luck...unfortunatly to be honest I bet it will be unstable too.....but it does not hurt to try. Maybe check for bent pins.

Not to sound anti-Intel....but I have heard of alot more Intels with bent pins than AMD, so you may want to check those out. That is not proven....just something I have noticed.

That's part of the reason for Intel going to the LGA775 pinless chips.

 

[@md0Cer]

Ah yes. I always thought it might be. Intel's must have thinner pins than AMD becuase socket 478 is actually alot smaller than AMD's socket 462, so they must have to use thinner pins and spaced closer together.

How are things going now??

 

[mattspalace]

Call me crazy but that vcore seems high for that chip... Anyone know what stock vcore is for a P4 EE?

Hmm.. Yeah stock voltage is 1.575v

Wouldn't happen to have a good pic of the intel heatsink would ya?

 

[ReTiCuLeX]

It's not retail, it's an engy sample

 

[mattspalace]

Your heatspreader should still have info.. Like 'Intel Confidential' and 'Engineering Sample'. Some other info as well..

 

[@md0Cer]

Would it at all be possible to show us a picture of the letters on the heatspreader?

 

[ReTiCuLeX]

I would, but they're scratched out =(
