Got any failure case here? According to the poll on OCN, only 70% success and the rest 30% failed miserably, quite risky to delid IMO.

Also does the value of the chip drop significantly after delid? Coz you're basically wipe the warranty by yourself, and I wonder who's gonna to buy delid CPU, unless it's very cheap and golden chip.

So far still none. I don't have any experience in deliding, but 1 try = success. Just make sure you do it really2 careful. 1 mistake can ruin your proc. IMO, yes the value sure drop but not so low. If you thinking to delid, make sure you find your proc's potential 1st. Its not worth to do it if your proc is a bad oc.

None failure case so far. But I can't deny that it is still a risky job. You don't want to ruin your best chip by carelessness.
When you have decided to delid it you don't care about the warranty already and so does the value of the chip.

+1. The best answer from a successful delidder.

Where did you guys get the Coolaboratory Pro and Ultra? Can't find anyone that selling here.

Hi... Want to ask.. I overclocked my i5 3570k to 4.4ghz and the temperature hit 90 under load using inter burn test.. Is it normal? I use asrock z77 extreme4 with offset +0.005v and cm hyper 212 evo

Seems normal to me. Under 95c still consider safe. Max temp before your processor start to throttle is 105c. Give it a long stress test to check for stability, be sure to keep an eye on your temp though.

wonder why my GFlops is low??
test with intel burn test..i got only about 97

Thank, i just copy the bios oc setting from internet
running 4.5 ghz voltage set to 1.3, prime 95 1 hour seem stable but need to test almost 24 hour right to be really stable?
temp average around 65 or below

I'd say run it for at least 3 hours but of course the longer the stress test, the better.
And don't forget to printscreen and share here. Good luck!

Alternatively, run Intel Burn Test or Linx with 20 loops, using max memory...

Will try, i run prime95 3 hour and the app crash
C1E enabled or not?

I got mine enabled...EIST + c1E enabled me to downclock...

hello i just upgraded from 775 board, still learning this offset stuffs hope to get more guide from sifu2 here

bulibulizaimon | 3570K | 4.4Ghz | Asrock Z77 Pro4-M | Air

I believe your chip needs more juice. Pump more vCore.

Welcome to Ivy Bridge club bro.
User list updated.

Sifus

pls give me some suggestion

my 3770k oc to 4.3ghz in 1.92v, memory us XMP mode (1600mhz) and stable in prime95 around 8 hours, intel burn test run stable in LEVEL maximum in 20 runs - 3 and 1/2 hours

temp idle 34'C, max is aound 80'C

using Asus p8z68-v

212 evo with two ac f12 fans...

I hope sifu give any suggestion to my bios setting:

I set manual voltage is 1.20V = idle and load voltage is the same (is this normal?)

I dunno how to set offset ...every time I set +0.005 or -0.005...the idle voltage will low but loading voltage still high (around 1.25v-1.3v) so I give up in offset...

ai over clock tuner =xmp
bclk:100
turbo ratio: cannot adjust in os
1 core:43
2 core:43
3 core:43
4 core:43
pll: auto
load calibration: 75%
cpu voltage frequency: auto
spread spectirm: disable
power phase control: extreme
power duty control: t.probe
cpu current capality: 140%
cpu manual votage: 1.20v
others : auto

I have try manual 1.95 for 4.3ghz but failed....I have try manual 1.215 for 4.5ghz but failed too... so give up
only 1.2v stable in 4.3ghz....
if I use asus auto OC...its run 4.4ghz in 1.288v....I feel it high so I don't use auto oc..

I still learning from all sifus here...pls teach me tqvm

Your GFlops in LinX seem abnormal, supposed to get more than 100, provided you are using the latest LinX and win7 SP1 onwards.
Perhaps a slight bump on vCore might help.

Depends on how your mobo BIOS behaves against vdroop/vdrop, afaik LLC 100% or Very High will yield the same vCore when idle & under load.
That means there's zero (or not significant) vdroop/vdrop.

Your BIOS setting is fine. All you have to do now is to figure out how much does your chip need the vCore at certain frequency. Take note that the vCore vs frequency is not linearly proportional but more likely in exponential way. eg.

4.0GHz @ 1.1v
4.2GHz @ 1.15v
4.3GHz @ 1.175v
4.4GHz @ 1.2v
4.5GHz @ 1.25v
4.6GHz @ 1.3v etc...

Offset mode works like this:

So you guys were using razor blade to delid right, which brand has the super thin razor blade available in bolehland?

I used a big stationery knife, but have to do it slowly and carefully so that I dont make any scratch on the PCB by accident and dont cut the die at the center.

I have no idea on razor blade i dont dare to use it lol.

I notice that the gap between IHS and PCB is very slim and tiny, r u sure stationary knife can delid as the blade of stationary knife is quite large.
