P4 saved me from my own stupidity!

Just a little story of my own stupidity...

Was putting in a P4 2.4B today (first one could only reliably hit 2.8Ghz @ 1.55v, was hoping the 2nd one I had would perform a little bit better). Anyways, I greased it up with some AS3, and connected the heatsink. Forgot to reset the BIOS, so the motherboard booted at my previous setting, 2.80Ghz @ 1.55v ... POST started, but the motherboard was beeping. Went to go into the BIOS to reset to Failsafe settings, and after I saved and the board rebooted, the box shut down! Didn't know what the heck it was doing, so I powered it up again ... Same thing, turned right off. Couldn't figure out what the hell I did wrong ... So I powered it on 2 more times. Then I thought about it and re-checked all of my connections. To my surprised one of the "legs" for the Intel Retail HSF was not all the way in! The HSF wasn't making contact with the chip properly, and the chip must have been overheating like there's no tomorrow.

Anyways, was really glad that the P4 had clock throttling at that point and the good sense to shutdown! Was able to boot this sucker at 2.80Ghz @ stock voltage, running a burn-in now at 2.88Ghz @ 1.6v to see how stable it is (unfortunately, I haven't been able to get this chip to stabilize at 3Ghz yet either ... but the processor hasn't burned in / AS3 hasn't settled yet ... so I'm still hopeful!) ..

Just glad I didn't do that with my AMD Rig, or else my XP1900+ would be a smoking hole right now!!! 🙂 Not trying to take shots at AMD in anyway, cuz I don't carry any preferences to AMD or Intel .. Without AMD there would be no good competition for Intel, and no reason for innovations like the AMD64 🙂

I am glad for clock throttling right now tho 🙂
 
thats a really good reason why you should not use that stupid black plastic HSF bracket or any HSF that also uses it 😉 🙂
 
Hehe, now don't dis AMD. Their variety of thermal protection has saved me in almost the same scenario.

Power the Asus A7N266-VM system on... *doink* it turns off again in less than a second. Turn on... *doink*. Turn on... *doink*. Why won't it stay running...? 😕 OH! MAYBE BECAUSE THE PLASTIC IS STILL COVERING THE THERMAL PAD, mechBgon!? COULD THAT BE IT, HMMM? :Q😱 LOL @ self... in my defense, I was building four computers at once. To err is human... 😉

THUGSROCK,

Its way too much effort to use the method that Alpha does with their heatsink ... I have the PAL8045 on my 1900+ and that thing is a HUGE pain in the butt!

Although the Intel HSF is a pain to take off too, the thing I like about it is that I don't have to remove the entire motherboard if I want to swap processors.

I know if I really wanted to, I could take the time into making a case mod that would allow me to remove the heatsink w/o removing the motherboard ... but thats way too much effort, especially if I ever change motherboards and the 4 holes end up in a different place.


 
my alpha is a pussy cat ~ couldnt be easier 🙂

i dont understand why so many ppl think theyre a pain 😕

ive swapped my cpu out at least a dozen times ~ never had to remove the moboard.

Hey, nothing against the AMDs at all! But I know my KR7A-RAID (KT266A) & XP1900+ doesn't have the right stuff to allow it to do what you just said. I'm guessing the newer AMD boards have implemented the Thermal protection, which is definitely a good thing!

EDIT: Oops, you edited your message after I read your message but before I quoted it I guess 🙂

(ORIGINAL) How often do you remove the heatsink from your motherboard?

I had to do it a few times on my XP and I found it to be a big pain to remove the entire motherboard from the case. Also the KR7A-RAID had the CPU placed in such a manner that the Alpha sat on top of one of the screws for motherboard mount... Didn't realize that at first and I had to get a pair of plyers to loosen the nut underneath the motherboard to get everything free.

EDIT: Anyways, I find it to be a pain, maybe it isn't as bad with the P4s since you get a lot of clearance around that part of the board for the CPU (which isn't necessarily true on some AMD boards).
 
NP, I know not all boards have it, very true 😀

Random thought from the eye of the brainstorm: I think that might be a hidden benefit of the integrated heat spreaders they'll be adding to the Hammer family, similar to what the P4 has now. With today's AMD CPUs, if the heatsink lugs break and the heatsink bails, the CPU's 45W-60W of heat production is essentially being absorbed by a tiny 5-gram sliver of bare silicon, which means a very fast thermal spike that could be hard to intercept. With an integrated heat spreader, if the heatsink were not on, the same approximate thermal load is being absorbed, not by a 5-gram scrap of silicon, but by 5 grams of silicon plus a massive copper slug that Anand called "the heaviest" CPU he's ever held. Ramp rates would be much, much more gradual.

2-3 times a month :Q

*so far 5 times this month

How do you remove the heatsink w/o removing the motherboard? Don't the little nuts which hold the heatsink in place fall off or shift around after you've unscrewed the heatsink? ... Or did you superglue the nuts in place?
 
the "bottom nuts" are just hand tight using 2 sockets.

never have they loosened.

ive had this cooler since May and i love it 😀

<EDIT> ive used it on 4 different moboards too

Oh thats right. Its been a long time since I installed the 8045 on my board. Its just the initial installation which requires the removal of the motherboard ... I guess if you already have the board out and know you're going to be using the Alpha it isn't a big deal at all (or if you're switching processors) .. The initial install is just a pain in the butt in the case where you've already got a processor installed and you want to change to the Alpha HSF.
 
Yeah - I found the P4 much more forgiving than the XP's.

I have smoked more Tbirds than I care to admit. I have never smoked a P4.

probably cuz its impossible to smoke a p4 for the most part 😛

have you made any similar mistakes with the p4 that caused you to smoke tbirds?
