To De-lid or not to de-lid.

[Dazed and Confused]

Should I de-lid my BE-2300 once my new CPU gets here or not? Would it be worth it to reduce temps on stock cooling @ stock speeds while undervolted?

Your oppinions below plz

if you are referring to removing the IHS (integrated heat sink) than i say dont. AS far as i know the newer brisbane cores have the IHS soldered onto the die itself. So doing so will destroy your chip as you take part of the die off with the IHS.

I recall something similar being mentioned on extreme forums (IIRC). Best bet is to look at some of the more extreme overclocking sites and looking to see if anyone has accomplished it (and whether it was worth it).

I wouldn't do it at all. These lids make applying thermal paste nearly foolproof.

 

[covert24]

why are we calling it "de-liding" now? back in the day it was taking off the IHS....

 

[firewolfsm]

The new chips have their IHS soldered on. You can do it though, there's a 50% chance you'll pull the die off the package with the IHS though.

Basically, slide a razor through the edges to break the TIM bond, make sure you're not going in too far.

Then take a blow torch and quickly, lightly, slide it over the IHS a couple times. It should pop off with or without the die attached.

So basically, no, don't do it.

Sooooo not worth the risk (though the BE you have is really inexpensive) but that's a pretty cool running CPU anyway so the benefit isn't all that great.

 

[Dazed and Confused]

All I'm hear is

Its pretty dangerous so *static* do it.

Outgunned, outnumbered, slim chance of survival. Let's do it

The harder you guys made it sound the more intrigued I was by the challenge so now I'ma do it just to see if I can :Q

make sure that cpu doesnt have a solder on like intel's.

there are amd's which have solder inside making ihs removal much more difficult.

 

[nerp]

Yeah if you do it and find that you've ripped the CPU into two parts, be prepared to have a completely worthless hunk of silicon. It will be neat to look at but will be beaten by a stopwatch in terms of performance.

At the lab we have access to some heatguns.

Anybody know if the solder is RohS or not? RohS and definitely will need a blowtorch. If it's normal solder, then a heat gun might work.

Very much so....

AMD has complied with the RoHS directive and, in fact, AMD products designated as ?RoHS compliant? have achieved the significant milestone of meeting the requirements of the ROHS directive one year in advance of the July 1, 2006 deadline.*

I was thinking about doing it to mine earlier, but, there's basically no point unless you've got water cooling or better. For several reasons:

1). The epoxy has a very high melting temp and is usually meant to be melted once and no more, so is dangerous for your processor
2). The solder is, of course, also of high melting point, and difficult to melt entirely as it is a square of solder around the CPU, but inside where the IHS ends
3). You're getting very very close to the melting point temps of the other soldered components (like on the bottom for instance) and without a very controlled heat application system (think BGA reflow-er), you're likely to melt the solder for those as well. Although this could be avoided with a steady careful hand, a pair of tongs, and waiting until the processor is cooled off before placing it on any surface again
4). The IHS is Nickel plated copper, both of these elements are great conductors of heat.

So, unless you're really ready to risk breaking your CPU, there's little benefit to be gained unless you are the utmost hardcore of overclocker. A better upgrade would be to simply move to water cooling.

sounds like the OP is going for it anyways, it's a cheap cpu, actually newegg was selling 2400BE for 25 a piece just past week so no biggie. Why not give it a try and satisfy your curiosity, but of course be prepared to waste that cpu. personally I doubt you will gain much unless you really OC that chip max. However, just by how well a direct touch HSF work compare to comparable sized regular HSF, I think you will gain a bit thermal dissipation by getting rid off the middle man 'lid'.

is deliding even worth it compared to lapping? (i mean, in terms of temperatures).

Actually, us AMD people don't have the problems you Intel people do with your concave IHS's Just because Intel doesn't care about you . . . . .

oh no, I see where this is going ... but hey do you know that AMD is dumping their fab completely by year end? so they might go from fabulous to ... fabless (oh noo!!)

And their plan to do so makes a lot of sense. It doesn't mean that they won't be able to make processors, so I'm not sure why you're bringing this up.

 

[taltamir]

from what I am hearing, properly lapping the IHS and the heat sink can drastically reduce temps to near room temperature. As in, from nearly 50c to just under 30c... So this is why I asked.
Forget the partisanism and answer the question, would delidding even give worthwhile temp benefits. Since the limit in OC on a lapped chip / lapped HSF seems to be something other then the temperature

 

[GundamF91]

Why dont' you lap IHS first, and see how far you can get.

I thought AMD + Intel signed agreements that they had to use in-house fabs so AMD couldn't piggyback on IBM's manufacturing capability and generate ultra high profit margins that Intel couldn't compete with. Hence TSMC never used for AMD's chips.

Graphics processors are not a part of this of course.

 

[firewolfsm]

If you're gonna do it anyways, the razor is the most important part.

Slide it in millimeters at a time, on each side, just to break the bond, if you hit the die, you'll fuck that up.

Also, give it no more than 1 or 2 total seconds under the blow torch, divided over a few strokes.

Is it just me, or does this seem like a disaster in the making?
