as far as delidding I actually paid a guy on ebay to do mine (he has done 100's of them and has amazing feedback)

he charges 25.00$ and will put on liquid ultra or another high quality TIM for you. When you consider a tube of liquid ultra costs 13.00$ this is a pretty good deal.

So for shipping with insurance <10$ and 25.00$ he will delid for you. He just did my 3570k and got it back to me asap and it is much much cooler running now.

That's not a bad deal, I might look into it. But for now the temp isn't really my concern it's that my Vcore is sitting above 1.300 just to get to 4.5...I refuse to believe that is okay, something has to be wonky.

Yeah you atleast have an h100 I just had a 30$ heatsink at the time.

Anyway I'm pretty familiar with that bios and I'm pretty sure your chip has just "hit the wall" and if you want to go further you are just going to need more vcore until it is stable. I always had the best luck with llc level 2 btw.

Heat will become an issue the more volts you put through it obviously so you likely need to decide if you want to stay at 4.4 or push further.

Truth is even between 4.4 and 4.7 you aren't gonna notice any different except in benchmarks.


As far as being wonky remember it is all a silicon lottery and you aren't guaranteed anything. Intel won't even take back a K processor that doesn't oc 100mhz if that is the only "defect" Which is a defect since they market it as an overclocker.

Well, that's a bit of a relief, the reason i'm pushing for a larger O/C is because I hear it helps with Microstutter, which I am experiencing since I added a second 660. talk about a headache!

Thanks for your help!

Most all chips idle than 1.000, so you can take Lucky23's suggestion to remove the offset and add it back in turbo. It will allow your chip to sip less power at idle, and will keep your loaded vcore the same. Heck, there are allot of chips that end up with negative offset because the VID table set by intel is just crap.

Yup I did take his advice and it does idle lower. Now I have to figure out just how much offset I need to get 4.8 stable for daily use. it is something over 0.0150 though which I don't know if that is good or bad for a 3770k or not.

I'm hitting about 80c in intel burn test with my water loop at 1.400 vcore but I'm gonna need more vcore I think since I had even more than +0.0150 in offset mode and ended up with whea errors.

I don't want to hit over 85c so I might just have to shoot for a 4.7ghz this chip is kind of a dud I think honestly, I wanted to push 5ghz with my new water cooling loop oh well 300mhz isn't alot.

edit(s)

yup whea @ 0.145 turbo voltage w/ +0.005 offset llc level 2

trying +0.0164 now.

You can always dellid smile.gif I dont know exactly where my voltage is, because I have the dang ext4 with its bad voltage readout and I lost my DMM in my last move, but I am pushing somewhere around 1400mV (could be more, could be less CPU-Z shows 1.32) through my chip and never see above 60C in IBT. Delliding will open up a couple more multipliers for you. Actually, dellid+direct die+water loop allowed me to use less vcore for the same multipliers because the temps were sooooo much lower than before. I run 5.0 everyday and barely scrape 40C gaming now.

my chip is delid and I have a waterloop now also. I don't really want to run direct die as it doesn't really make a big difference if you use liquid ultra under the ihs i've heard

60C in ibt with what frequency and you said 1.32 vcore? I guess that is 0.080 less than 1.40 like i've been running hitting 80c.

You on a 3770k also? This is my first loop but I think everything is setup correctly

Yeah my temps fall pretty much in line with people @ 4.7-4.9 @ 1.4x vcore on the stable club spread sheet filtered for 3770k entries only.

Also that is my 1-2 hottest cores some are 6-10c cooler

Tested running p95 for like 14 hours with zero issues. Average temps are like mid 60's with my H100i in pushpull out the top of my air 540

The minute I try to start bumping stuff up from there is where I have major issues, i'm able to get 4.5 to boot to windows with a +0.047 turbo and +0.005 offset but my vcore is sitting at 1.328 max according to HWmonitor and my temp hops up to the mid 80's! This is f**king insane! It runs p95 for a few minutes and then BSOD's with various errors. I've tried lowering my LLC to 3-4 to get some lower voltage and temps as well as moving my offset to -.005 but as soon as I do that it doesn't even want to boot to windows anymore.

I am so frustrated i'm just about to sit at 4.4, but 4.5 was my original goal for my daily use and I feel like i'm close but there must be some stupid thing i'm missing. mad.gif

I have the same exact problem and it has been driving me nuts. The funny thing is that I am also overclocking to see if it will help with the microstutter that I am experiencing in BF4.
Do you also have a low VID on stock 3.5GHz speeds? Currently, it looks like I have a stable 4.5Ghz OC with +0.07v offset and AUTO on Turbo and L2 (I know this isn't ideal, and I'd prefer to use Turbo rather than offset).

Maybe we can help eachother out.

You should turn turbo off of auto and attempt to find how much it actually requires instead of allowing your motherboard to assign what it thinks it needs to, by adding additional turbo voltage and stress testing until it is stable. VID has nothing to do with the actual voltage requirements for your chip, it is simply a reference point that the chip uses when you are NOT overclocking. So asking his chips VID is about as useful as asking the color of his socks.

Voltage requirements scale with multiplier and are also affected by quality of chip. the extra voltage to go from 3.9 to 4.0 is going to be allot less than what is required to go from 4.5 to 4.6. Dont let the amount of voltage added in bios scare you, there are several different things that can affect the amount of turbo needed. The only numbers that can get scary are VCore and temperature, as long as those stay within comfort zone it does not matter if you need to add .004 or .186.

Keep trying, keep adding turbo until you succeed or fail due to temps/voltage.

Thank you for your response.
I now understand that VID is a reference point used to determine the offset needed to have proper Vcore. How do you determine your VID though? Is this the VID that is displayed in Coretemp at stock clocks when idle or under load (the number changes at x16 and x35 on my 3770k)?
Can you also follow a formula and take your VID and subtract Bios vcore to get your offset, or does this not really work?
Thanks in advance for helping.

You dont, intel does. Vcore = VID + offset + vdroop +(at load)turbo

Dont worry about VID, it has no use here. Only look at your VCore, concentrating on VID will get you distracted, you dont have any control over it any way, and it does not affect your overclock.

I tried to overclock my 2500k with Asrock z77 Extreme4.
I disable PPL Overvoltage, set all power limits to maximum, offset voltage to +0.015, LLC level 2, disabled C3, C6, Package C and set CPU ratio to 44.
Now, when I start Linx test, cpu works on 4400Mhz (as it should) for about 10 seconds and then drops down to 3800-4100Mhz.
For me, it looks like some overvoltage\heating protection, but temperature (60-65C) and voltage (not more than 1.4V) are ok.
