De-lidded 3770k!!

Nickolp1974 · 16 Oct 2012 at 15:26

*WARNING*
This will only work on IVY's, sandybridge heatsink top is soldered.

well got a 3770k about 5 days ago and after a little play i thought temps were a little high!!

this is running prime for 10mins @4.4ghz/1.25v

so did a little reading and thought what the heck i'm gonna have a go!!!
plus going under water so thought that it would benefit from the operation.

lid on.

Under the knife, slowly slowly!

voila, lid off!

time to clean that mess off, did it the best i could for now as i need some better tim, used AS 5 for now.

all back together in my PC, it fires up!!! nice, i've not killed it!
right same test, 10 mins of prime and NO settings changed.

Well i'm happy with those results, took me half an hour from start to finish, well worth it, and the temps should get better when the tim cures a little

thx, could be better as i think the mounting mech on the HSF(dark rock) is on its way out as i can tighten all the way.

did you nik the pcb underneath at all? its very easy to destroy the chip but well done

btw what cooler did you use??

no, theres a very tiny mark but i wouldn't call it a scratch.
once i freed a corner enough to get the tip in it was easy. Iwas more worried that the tip of the blade would snap, but all was well

did you just push in the tip of the blade all the way around? i have to admit its rather daunting,starting off is the worst part

using just the blade on a corner just rocked it side to side, you do need quite a bit of preasure but once through just ran the tip round, had a picture of someone else's next to me on my ipad so i could roughly judge how deep to go in. The top and bottom is the risky bit as the core is quite close.

did mine a while back but i use liquid pro underneath and have never looked back. If ivy could take 1.45v/1.5v 24/7 I would be laughing @ 5ghz im just hitting 90c O_O

Only had some arctic silver 5 and some old thermochill which had gone watery and lumpy! I am after some of the liquid pro stuff.

I'm surprised after all that effort you did not go for an adjustable heatsink design and keep the lid off.

Not really much effort, just a risk! Should be under water in a about a week so will look at that then

Brave For ~10 degrees difference

10 degrees can make all the difference

So I assume the fact AS5 is capacitive doesn't cause a problem?

it appears not too.

steve258 said:
Nice! Was gonna make a thread about this as well. Do you still have the IHS on after replacing the thermal paste?

I found that I got 10C difference just by replacing the thermal paste, and another 10C+ difference with the cooler directly mounted on die, so a total of 20C+ less temp. I'm able to run it at 4.8Ghz as a result.

yeah the IHS is back on, once underwater will have a play without the IHS and with some liquid pro which is meant to be about the best replacement.

and a 20c drop is quite an achievement :cool:

One Brave person, can you do mine when i get it ???

i have only done it as its going in a water cooling setup, where its meant to help. It is not advisable for all.
4.4ghz is more than enough which should be easy on air, anything more is just bragging rights

Very nice. Have you been able to push the frequency up as a result?

had a quick go but i think i have a problem with my ram, this happened before the de-lid, keep getting irql_not_less_or_equal, which apparently relates to ram, have ran memtest once but no errors. got some spare corsair kicking about so i'm gonna try that

Nickolp1974 · 16 Oct 2012 at 19:12

so is direct contact meant to be better?

In theory it should be yes, though I would imagine you stand a chance of damaging the die which = dead cpu

Btw, you have balls of steel

maybe not worth any more risk then!! not to gain a few more degrees, besides i'm hoping them monsta's are gonna do the job

Nickolp1974 · 16 Oct 2012 at 21:17

Been running prime now for 4 hours @ 4.5Ghz/1.29v. Max temp 79, lowest core 68.

Does lapping help the temp core spread at all?

Nickolp1974 · 16 Oct 2012 at 22:14

pgi947 said:
It can, but IMO its another pointless exercise that could result in a dead CPU if you're not careful.

Lapping may give another 2-3c I would say at best.

Probably not worth it then.
Can i set cores individually, does that help or is it all down to the voltage applied as a whole?

I thought about this but I am a clumsy oaf, so it's a no no Well done for being braver than I

Once my loop is complete, maybe have a go at direct die, whats the worst??!!

Crushed core, dead chip.

Best cooling performance is to go naked. It should allow you to reach similar clock speeds and temperatures to SB.

Edit: You need to make sure your cooler can compensate for the difference in height.

When you say naked, can you explain?

Nickolp1974 · 17 Oct 2012 at 23:07

Jokester said:
No IHS.

Is that not direct die??

Then i'm thinking whilst the cooler+ihs is on make a shim stack to get an approximate height, so as not to crush die?

Or is just getting some liquid ultra under the IHS nearly as good?

Nickolp1974 · 17 Oct 2012 at 23:33

Just had to post this, what a douche.

Ouch, what happened? I have plenty of time to be very delicate with it, my razor blades can take idividual layers off your fingers, should be nice and sharp. Guess I will have to try and soften up the glue with a hairdryer though.

I think it will be very hard to sell a de-lidded one in a few years - this is what is putting me off, not really worried about damaging it. Seen some really brutal jobs of it on youtube lol.

I wouldn't use a hairdryer, in my experience with glues, sealants and silicones there better cold, and using a new blade its easy.

And as for selling, theres plenty of sealants which can withstand the heat so sticking it back on is not a problem

Nickolp1974 · 18 Oct 2012 at 12:40

@Rossi regarding the TIM, is liquid pro/ultra conductive as this is the best known to lower temps and most used in de-lidding?

Nickolp1974 · 20 Oct 2012 at 08:28

Just caught up on this thread, @BrianB, dam thats awful news, have you inspected mobo cpu pins there so easy to bend, do ya have a magnifying glass so you can have a closer look. Again sorry to hear about your loss

Is that the nick to the top right corner?? Is there a break in the pcb track??! I had a mobo with a broken track and managed to repair it.

Do NOT put nail polish on until you have checked the nick(golden bit is the track, there like very thin copper ribbon which can be easily broken) and check them pins!
