***Official Intel Haswell Thread***

A little reminder to all who are looking into delidding Haswell, those little capacitors next to the die can EASILY be taken off. Here is a dead one already with 2 capacitors chipped off:

Just be careful. With Ivy Bridge the Razor method is decent as long as you're careful, with Haswell you can easily nick one off being too rough or cutting too deep. Go for the vice method with Haswell!

The board doesn't seem to be damaged, just those two SMD components at the top. You could probably have a go at re-soldering them with a steady hand and a magnifying glass. Nothing to lose, right?

Just got my first ever win8 blue screen with sad face.
WHEA_UNCORRECTABLE_ERROR no idea what it means.
Click to expand...

type event viewer in windows search.then look in warning or error

it should tell you what the warning or errors are,usually cpu parity 19 which means you need a higher level llc or a touch more cpu voltage

can also be memory but it will say memory ect
 
There is a news item on pcpro.co.uk talking about increases in temperature and lower clocks on retail versions of haswell.
 
Basically you will need to delid to get that performance back. Seems delid = 20c drop using clp/clu.

Unless I can do 4.5GHz stable, I will probably delid now rather than next year. Just need to wait for that Asus Maximus Hero to arrive next week to find out.

I think i'll leave any OC until some tutorials appear, ive no idea what all these settings mean. On my x58 i just increased BLK and VCore and off it went.

This is exactly the same. Granted if you are complete noob, a guide will help you get a better overclock, but just changing blk to 42 and vcore to 1.2 should easily net you 4.2GHz. Then later you can use guide to venture to 4.5GHz and beyond :D

if you have a 4670k here's an easy 4ghz

Leave everything on auto/default
Change the core clock to 40x , change the uncores all to 40x
raise the vcore by maybe 0.01-0.02 (you might not even have to do that) (I'm at 1.152 but never checked if I could do it on stock volts)

(uncores is what the ratio of each core gets boosted to from intels core boost thing)

if your getting whea errors crashes it usually points to low cpu voltage

that's the case on ib,can't see haswell being different,still same error
 
agreed - I needed about 3 steps up in voltage to go from Prime95/Handbrake stable

to both of those stable with no WHEA errors in error log

quite a bump in volts
 
Just delided a Celeron chip with the razor blade scraper tool a posted a few pages back, the good thing about this tool is it makes it almost impossible to push the razor blade too far in as the plastic of the tool stop this from happening.

Wasn't too hard at all especially when you take into account these are soldered chips.
 
Now I believe Intel have stated that the reason why their using TIM rather then solder is because of the 3Dtrigate transistors. If this is true then have we reached the limits of silicon in terms of clockrate?
 
Just put 1.2V into my chip at 3.6GHZ under my water under prime it's about 55c.
Given my loop's rushed as hell and quite frankly needs a new radiator, I'll claim it a victory :p
And it's got so many air bubbles in etc lol.

EDIT : Interestingly my chip won't go down to silly 0.1v etc anymore, lowest it goes it 0.7v

What is stopping you going 4.6 now that you on water? Worse case is it won't work. Not like you will damage CPU. Very safe to go up to 1.3v on core as I understand it.

My rabid instability problems :p
Just before, I was on the stock cooler, now I'm not so I can chuck volts at it and see what's wrong.
 
Start from 1.2 and work up to 1.3v. Should get at very least stable 4.4GHz. If not you either have a poor chip or something else wrong. GL HF :)
 
Got the top off, was easy enough, but then noticed some loose smd on the bottom. Doh. Wasn't aware of slipping with my delidding device to bash them.

Gave it a few whacks and it just loosened off slowly rather than pinged off, in the end was just able to lift it off the IHS.
