Overclocking 4770k Results

That is all I wanted to prove.



Delidding is more involved than just changing TIM. Go to the delidding club link to study out what I have shared and you will not need be bothered about proving your points that many people have already learned from experience.

What are you trying to say? All thats in your link is info on how to delid and people posting up their results, whats your point?
 
As far as the "negative attitude", I don't have one towards delidding. I just don't like it when people tell others false information about why delidding helps temps. A bunch of people believe it is soley due to TIM, not true. It is due to gap/height reduction between IHS and die. That is all I wanted to prove.


Who in this thread has said this false information. You came in this thread raising hell about people spreading lies about the TIM. Who upset you?

Somebody mentioned delidding and then you felt obligated to enter the thread and accuse people of spreading lies?


If you would have quoted what set you off it would of been easier to interpret exactly what you were doing. I don't think your accusations were necessary to the discussion.
 
I tried two chips from newegg. And 95 to 96c seems the max temp they like to get to under prime95 using blend test. Room temp 72F,cpu 4400mhz, voltage 1.268, ram 2100mhz. Noctua NH-D14.

Hmmmm, now that I went back to read the posts, I guess I misinterpreted some posts. Sorry about the outrage. You do know what I mean though, when you read tons and tons of threads about delidding, there is always someone who will mention that it's Intel's "crappy TIM" that is at fault. I apologize for causing a commotion! :)
 
Batch# L307B240
4.8 ghz/1.445V/2.0VCCIN/4.0Ring/1.2RingV. Undelided. Only ran Aida for 30 min on cpu test. Max core temps of 82C.


Can do 4.7 ghz 24/7 using EIST/enhanced turbo/adaptive voltage/cpu offset +0.15.
Most likely wont be able to do this even at 4.8 cause the cache voltage spikes at 1.49v and the vcore hits 1.45v with 4.7ghz during Aida testing.

I've come to the conclusion that unless I find some way to get those voltages down there's no point deliding. Heat's not going to kill it, the voltage will.

My chip seems to be identical, +0.15 offset with 4.7GHz with all the power states and what not. Adaptive voltage hasn't been useful- the "additional turbo voltage" doesn't help me reduce the offset at all.

How much does cache voltage spike during AVX load? I'm using a +0.3v offset on my cache to get 46x, but my motherboard doesn't have a cache voltage probe so I don't know what it's doing.
 
Another update:

I try out 3 more chips. All of them were Costa Rica....2 were plain fail in overclocking...both requiring 1.375v to even get past 4.4Ghz stability test...and 1 was okay, able to be stable at 4.5Ghz with 1.375v.

The original and surprising first purchased CPU is still the best. The rest went back to the vendors... I feel so guilty for all of these returns!

I have great news though! I installed an updated ASUS MAXIMUS HERO bios and am surprised! My original chip can be be STABLE at 4.8Ghz at 1.375v (up from 4.6 pre-bios update).....AND the temps dropped by 5-10c under 100% load! I highly recommend you run to your MOBO manufacture and update the bios.... it appears something was missed pre-Haswell release and is now fixed! MSI and GIABYTE also released a bios around the same time. Go get it!

Probably because ASUS updated the microcode from revision 07 to 09. You can check in HWiNFO64 or AIDA64 to confirm.

Dear God, maybe there is hope for Haswell after all...I wonder if there is another "bug" in the first Z87 chipsets other then the USB3 issue and Intel sat on it?:eek:

Micro Code 9h available for Gigabyte mother boards?

I checked your board and the latest F5 is using 7h.

But it's pretty easy to replace. First download the updated microcode file. Using MMTool, load the BIOS file and go to the CPU Patch tab. Select microcode 0326C307 and delete it. Then insert the new file labeled 0326C309.bin. Save Image and close MMTool. You should now be able to flash it in Q-Flash.

I'll check my ud3h when I get home. Giga released an updated BIOS 7/20 for it that I installed over the weekend. It's still a beta bios (F6f), but it's been stable at my regular F5 bios OC settings, and it helped my RAID speed a bit along with a better mouse control in the UEFI HD screens. A FAR better BIOS than F5 was for sure.

For that 4.8GHz, do you have power saving states disabled?

Thanks. :) I was able to change the microcode but it placed it as number 3. Does it matter?

ASRock is the same. :( I had to manually insert mine. Then again, I manually update all of the OPROMs so it's not a big deal for me.

I won't lie - that program confused the heck out of me. Documentation wasn't quite where I needed it to be to understand as a first time user. Wouldn't mind updating the microcode to see if it helps increase my OC.

Thanks again solidbladez. Going to try it out soon.

I tried it yesterday and the system rebooted right in the middle of the BIOS flash. Didn't seem to affect anything, it booted as normal and the microcode say 09 when I checked it afterwards, but my previously stable overclock crashed, so I flashed back to the real BIOS. Let us know how it goes when you try it.

Did you try the 09 or the 10?
 
Can people stop spreading bullshit about the "bad" compound that intel uses on the die? Delidding helps temps NOT because of a TIM swap. It helps because of the gap reduction between IHS and die! By delidding, you get rid of that black gunk and slather of TIM that is creating an offset between the IHS and die, allowing to close the gap and creating better contact. It has been tested by "idontcare" on anandtech forums in a very scientific and controlled manner.

"Notice that the Intel stock CPU TIM outperforms the NT-H1 replacement TIM once the CPU-to-IHS gap is identical" (idontcare)

Sorry, I'm just angry that people don't understand WHY delidding is helping their temps and just assume it is the TIM. IT IS NOT!

Get reading and inform yourselves and stop spreading BS please.

Well, Intel used to solder the IHS to the chip with 2600K and prior. I believe that is why people are so angry with Intel.
 
I'm going to wait for an official bios update from gigabyte from here on. Installed the 10h, and though I could stress test just fine at my normal OC, the moment I went to play games I would get driver crashes or game lock ups within minutes. I had to drop back to 4.1GHz to be stable in game even though linpack would run just fine for hours. I didn't change anything else - just dropped in the microcode as the instructions in this thread show. I can bench and OC like a Mofo now (was able to run a few stress tests at 4.9, but that's the only thing I could run), but actual usage leaves a little to be desired. :p
 
I'm getting good results with the new X01 BIOS for my Gigabyte Z87X-OC with the 10H microcode patched in it.

Running a new beta Xtreme BIOS designed for liquid nitrogen overclocking, seems to be geared to pushing memory with unlock voltages that help memory. I focused on memory and was able to get 2600mhz CL9 from my Gskill 2400mhz CL9 kit. With my Z77 Mpower and 3770k I could never get this kind of performance from this kit.

4.7GHZ, 2600mhz CL9.

My system setting freaked out CPU-Z validation: http://valid.canardpc.com/2873741

Not completely stable yet though but much more stable then anything I have done up until this point. Still tweaking.
 
I have a UD4H still running the F5 bios that came on it from the factory and Aida64 reports it having the 9H microcode.

Also my 4770 has been running 4.3 @1.2v, havent tried faster yet.
 
Update:

I tried 2 more chips...both Costa Rica and the same batch number. I am a bit confused... One of them, couldn't boot at 1.375 4.5ghz, but the other is running a stability test with really nice temps at the same voltage, but 4.6ghz. This chip's temps are 10c cooler than the original chip at the same settings. Seems batch numbers are meaningless and it is all random. I might have stroke gold with this Costa Rica chip...

Btw, after the bios update, the original chip is somewhat stable at 4.8, but it still crashes randomly, so I had to go down to 4.7. While it ran stable during AIDA tests, it crashes while gaming, so I took it back down to 4.6/ 1.375v, which has been 100% stable running for weeks.

Edit: The Costa Rica chip seems to be stable at 1.4v 4.8ghz so far. I had to increase VCCIOD to +0.25v to stop watchdog errors

Running 2 hours stress teat, seems this chip is stable at 1.45v 4.8ghz and the lower temps make it doable . Oddly, the temps are under 80c, but peak at 95 rarely. The original chip was similar, but at 1.375v and 4.6ghz...doing 1.45 resulted in unworkable temps on a Corsair h110. Oddly, core 4 seems to be a good 10c cooler than the others. Idle temps are only 25c at 1.45v, which seems odd because all other chips have been 30-35c. It seems this odd chip is simply colder...wonder how this can be...especially since it was in the same batch of a crappy chip.

This is more than likely related to Intel's inconsistency on seating of IHS. You can see many people have lowered temps by up to 30c+ when delidding and getting good contact mount on die with IHS to block or direct die to block.
 
Okay so after a lot more longterm testing, this chip requires 1.41v to be 100% stable at 4.6ghz. The temps are decent at this voltage, but anything past it I don't think is worth it.

Ever since BIOS update, stability seemed to have increased, but long term testing still leads to crashes. Basically, crashes are less frequent as if there is more of a buffer, but they still happen. IE, instead of a chip crashing after 5 mins of a test, it now can take hours.

This chip can do 4.7 or 4.8 for a decent amount of time (2-12+ hours), but it will still crash eventually.

My original chip was able to run 4.8ghz with 1.375v for a decent amount of time, but will eventually crash (unstable). This one is similar - it can run 4.7 or 4.8, but seems 4.6 is the only freq that is 100% stable and the temps are okay.

Honestly, I am fixing to give up on getting 4.6ghz or higher. 4.5 seems to be the best overclock for these chips considering temps. Going from 4.5 -> 4.6 is only a slight performance increase, but the temps go up disproportionately. These "better" chips can be 100% stable at 4.5Ghz with 1.25v and have core temps never even spike past 70c.

I did physically compare the 2 best chips so far (the original Malaysia chip and the new Costa Rica chip) and it does seem that the Costa Rica chip is thinner. It is really obvious when you insert it into the socket, where the Malaysia chip is a really tight fit (the socket clips actually make a little indent in the heat sink and there is a crunch sound), but the Costa Rica is looser (though still kind of tight). I think the theory behind delidding to reduce the die and heatsink gap is a valid one. And based on comparing these two, I think it is very reasonable that delidding the chip is the only way to get a reliable 4.7 or 4.8 with reasonable temps, but I have to wonder... is .1 or .2 ghz worth a beheading.... maybe the Malaysian is.

I have noticed that the Costa Rica chips get the watch dog BSODs, but I never see that with the Malaysian chips. My overall impression so far is Malaysia > Costa Rica... because the Costa Rica chips require more voltage always. Seems the Costa Rica chips are cooler though (tighter seal/ less gap)... but both of these are from my sampling and perhaps you will see a variation.

Batch numbers seem meaningly and the CPUs are really random. I wouldn't get anal about finding the right batch number... but I do think Malaysia chips are a better bet.
 
I've noticed the same long-term stability problem. Sometimes it takes many hours, sometimes only 1 or 2, but it inevitably seems to BSOD. I have also observed this at Optimized Defaults with memory at XMP 2133. I'm wondering if it's some motherboard components overheating, although I can't do much better than the 200mm fan currently over the motherboard.
 
All my Malaysia chips barely did 4.2ghz at 1.20v. Temps were always in the 80s or even 90s. Batch L311B411, L307b189.,and L312B322
