3770k IHS Removals - CPU temp dropped from 79C to 71C

[andressergio]

Not a good comparison but seems that Liquid Pro is just slightly better than Liquid Ultra.

Liquid Ultra:

* LinX for 7 hours with MVF

Liquid Pro:

* LinX for 1 hour with OC Formula

Both tests were done without IHS and ambient temp @ 33-35C

agree with you owi

[CrazyNutz]

Ok. Delided my 3570k. I first tried some thermal fusion 400 while I waited for my liquid pro to come in. Got about 5c lower with the CM thermal fusion.

Now my Liquid Pro came in, I cleaned everything up put the LP on the die, and a super thin layer on the back side of the IHS.

WOW this is the solution for sure folks! I got >20c lower at load!

well i just got a new 3770K batch 3224B259...wich i can boot into windows at 5Ghz HT at 1,328 if i put my SLI with the Galaxy's GTX680 SOC needs more but look temps
IMC is great goes to 2933

this is 4.8HT 1.328 NO IHS REMOVED and mem 2800CL11 Room is 25C



My other chip was 98C !!! at 1,35v same ambient

i found the screen !!! OMG







Cheers to all

Nice chip Sergio! Do you think it can handle some linx at that voltage?

[Alex-Ro]

Good chip buddy,make sure not to damage it when removing ihs

thanks buds yes it can handle

and i already removed his to 7 chips no damage, some ppl are having problems scratching PCB cauz the put on a flat table so they dont have the correct angle to put the blad, grabbing the chip with the hand is the best method

but this chip i show wont be removed i luv the temps and all keeper !!!

Cheers !!!

I might have screwed up my i7 3770k while removing the IHS, the green pcb outside of the IHS, the blade chopped off some green stuff from surface of the cpu, it shows up some copper.
Channel A1 and A2 memory slots wont work but otherwise cpu works fine (error 55, memory not installed when i put memory to A1 and A2 slots), need figure out if i can still fix this cpu.
And there are some slightly bent pins below same spot in socket so it could be that it didnt damage at all but pins just dont make contact.

[hersounds]

That's the risk we all run...
Look at these pictures are of an 3770k killed in battle ( mine not, from spanish forum )

^^Sorry, but that's a stupid way to waste a good working cpu....Too bad not even go cold yet

[Brama]

Probably spanish guy used a machete...

[rintamarotta]

Lucky i only broke Memory Channel A from CPU, i tested the cpu otherwise and apart from Memory Channel A its working without problems.
So memory bandwidth is bit lacky at 15500-16600Mb/s when it could be double that, but at least this IMC on the cpu can do something like 2400Mhz with my G.Skill sticks that are rated for 11-11-11-31-T2, but im running them at 10-11-10-28-T1, maybe could go to CL9 without problem.



Bit slow at HyperPi tough :/

[hersounds]

probably spanish guy used a machete...:d

lol!

[rintamarotta]

I used "utility knife" or "stanley knife" at start but soon as i noticed it started to go wrong i switched to thin razorblade, should have used razorblade from start so there would have not been damage to cpu.

This is one wierd cpu, running 1.40v at 4.8Ghz is faster in Cinebench and LinX than 5Ghz at 1.5v and that 5Ghz is at least 2hours LinX stable.

I have a QX6700 which is missing a small part broken off the green substrate but it's at the edge. Some copper could be seen as well. Has been running for 3 years already, the damage was already there when I got that CPU.

[rintamarotta]

Yeah, i think it will run fine till i deside to send it to garbage bin. Going to buy two other i7 3770k's anyway in next week, so i think ill just do suecide run with this cpu, 1.8-2.0v and 5.5Ghz in phase change when other i7's come in from my mailbox.

Or then im going to fire up my soldering iron and actually solder those points where copper is visible and then test what happens, need just get some cheap Z77/Z68 motherboard to sacrifice for this cpu.

when highers speeds produce lower results than lower speeds means that something aint stable...

Probly because of no retention bracket used on mobo's socket cpu wasn't make full contact with socket pins

[rintamarotta]

All pins make contact, its clearly visible from pads in bottom of CPU. Damage is in green pcb of cpu, there is two places where copper is visible and i think one of the visible copper ones have disconnected "wire" going to socket pin inside the cpu pcb so i might need just fix it by using copper conductive pen to reconnect the "wire".

And i use retention bracket to hold down cpu, i just put in proper thermal paste betwean cpu and ihs.

Gave my second 3570K a try since i failed and only single channel working on the first one. This one works 100% and with custom cooling i?ll get around 60 degrees with 100% load and 4.5ghz with 1.3v. I?m happy Before with stock i got 81 at the highest core. Using LP on the die and mx4 between IHS and Cpublock

[andressergio]

less volts with new bios 1408 NO IHS removed and 25C ambient room summer
