Killed CPU :( New 3570k or 3770k?

I once read an article where someone used toothpaste as a TIM.

I don't think the heat spreaders one C2D's are as well attached as Ivy/Haswell. I've had a couple of C2D and P4 heat spreaders come off with the heatsink before!

probably down to all the heat cycles over the years, weakening the adhesive

It varies from chip to chip m8, my 3570k one was on a lot tighter than my 4790k, i think its just depends on the luck of the draw. Some of the old chips were a pain to get off, i remember a couple of the early amd FX chips were a pain to delid, and them sandybridge are a nightmare to get off

(please dont try that)

Bought some razor blades (proper shaving ones) for £2. Asked around if anyone had a vice I could borrow, but couldnt find one, so took my £2 blades to my £160 CPU instead of buying a £30 vice lol.

I'll probs buy a used 2600k as suggested, as its only about £15 more than a used 3570k. Used 3770ks are not cheap at all!

Unlucky mate.
I delidded my 3770k a couple of months ago an decided to use the vice only method.
Took 5-10mins as I was bricking myself.
Bought a £18 vice off Amazon and returned it as soon as I delidded

just bought a 2700k from a MM for a very reasonable price , upgraded from a 3570k I'd say the 26/700k is worth it

I killed my 3570k by trying to de-lid it with a razorblade make a couple of nics in the pcb, enough to see the copper beneeth the green stuff. Put it all back together and now when I turn the pc on, the fans spin, but nothing is displayed on the screen, and it doesnt boot into windows cos the fans never back down like they normally do in windows. So it looks like I broke it

So now, I'm obviously in the need of a new CPU (which I can confirm I will not be trying to de-lid). I bought the i5 3 years ago or so, because then, nothing was making use of more than 4 threads. Now, there are a few games that the i7 pulls ahead right? As I'm already going to have the shell out the £150 odd for nothing but my stupidity, I'm wondering if its worth the extra £100 to make it an upgrade?

Thoughs?

And yeah, I'm an idiot, you dont have to tell me...

Bad luck.... I used a block of wood when de-lidding mine, it was very easy to do... I'd suggest u try it again with this method

I can't think of any game which would benefit having an i7, in my experience

And it wasn't doing completely dreadful either, if I recall correctly...

Maybe that is what Intel puts in the Haswells

Only a few degrees worse than poor 'proper' TIM, and they tested pink lipstick too

Chocolate not recommended!

Well Battlefield 3 uses up to six cores so there's a start. Crysis 3 can demolish 8 cores on certain levels and BF4 mutliplayer runs better on an I7.

Running Windows 8 you will see far more core activity also, given it spreads the load around. 7 wasn't so hot and didn't natively support more than 4 so it's core parking hacks FTW.

I got my 2600k now.

It doesnt seam like the best clocker at first glance.

4.5Ghz @ 1.35v failed prime95. Any other settings worth tweaking? PLL I only have an option for +0.1v which seams like a lot...

4.4Ghz is looking good so far @ 1.328v. But thats pretty high volts for the clock.

wazza300 · 22 Jan 2015 at 22:31

What board and how much ram? Its not too bad,mine needs 1.344v for 4.5ghz

ASUS P8Z77-V LX (weak VRMs)

8gb samsung green running @ there xmp profile of 1.35v @ 1600Mhz.

wazza300 · 22 Jan 2015 at 22:37

You simply might need more vcore

Can help you with that ram though

Try 2133mhz and 1.55v dram voltage,9.10.10.21.1t timings that's what I'm running

Thanks. I had a nice OC on the ram when I was running the 3750k. But after the bios flash and new CPU, I'm more interested in the CPU atm.

MOAR vcore is cool. I'd like to have a profile saved for a sensible OC though, so thats what I'll aim for first, somthing under 1.35v.

Whats the thoughts of a voltage range that will almost definatly last 3 years. 1.45v sound about right? dont worry, I wont sue lol.

wazza300 · 22 Jan 2015 at 22:46

I wouldn't go above 1.4v for 24/7

Are you adjusting the vrm response?I forget what kts called now on Asus without looking

Hmmm, IDK what that could be. I've changed LLC, thats about the only other setting I've touched apart from turning some things to normal.

its phase control and duty control,

new boy · 23 Jan 2015 at 22:03

Thanks for that.

I've managed to get my voltage down to 1.312v @ 4.4ghz now. (or at least, its looking promicing, havnt finished stress testing yet.)

Meh, grabbed a used 2600k.

At least I cant be tempted to do it again now lol.

Bump.

Soooooooooo.

Here we are 6 months later, got board of the 2600k, sold it, got a 4790k.

CPU is great, a nice clocker, however, I am rather temperature limited...

I'm... Tempted.

Did anyone else actually use the dental floss method on a non soldered chip and have it live to post the tale? Defiantly wont be using the razor method again if I do decide to do it lol.

EDIT

Might buy a few of those pentium chips to have a practice on as it appears they are not soldered.

You can literally get two E5200 CPUs delivered for less than the price of a pint of Guinness down my local lmao.

Hit it with a hammer.

You don't even need a vice as I have seen vids on youtube of people doing it with a hammer and a couple of blocks of wood. I had no choice with my 4670k as there was no gap at all between the pcb and IHS to even start with a blade. It's a extremely nervous moment and it's surprising just how hard you have to hit it to get it off!!
