Seems like a sloppy TIM application or the IHS isn't lined up properly, you shouldn't have a 14c difference in core temps like that regardless of the paste you use.

That's what I thought but I can't help it. I reseated a bunch of times, not sure what to do. That core has always ran super. Hot

It just seems odd that the temperature gap would increase after the delid. For the sake of testing all the variables, could you rotate your 620's block 90°?
post #19164 of 33558
I could try that. You think that will help?

I did notice when at first the temps where bad that my block was not touching the CPU on one corner. I cleaned and added thermal past. Temps got better, but that darn one core is always running hot. I put a level on the mobo, and CPU to make sure everything was straight and it was.

I will try to turn block around when i put my kid down for the night. will post back in a few. Any other ides are welcome, and plus rep for helping me skullwipe. thumb.gif

Doesn't sound like you have an 'awesome' chip or golden one, ie 5ghz@1.39-1.43, but you might have a great one still. Mine was able to do 4.8@1.4, 4.9@1.45, 5@1.5v.
I'm working on 4.8ghz right now. Ill let you guys know. Another noob question, how much does ram affect cpu overclocking? at all?

With Ivy, not much at all in my experience (unlike haswell). That said, tune your CPU overclock first. A 620 is a rather low end cooler so you are probably going to be limited to around 1.4v.
Quote:
So at 4.8ghz @1.4V I am "stable" but google chrome will crash if I am also running prime, this happens all the way up to 1.475V. Whats happening here? Prime gives no errors and if prime is not running chrome is fine.

Then that isn't stable... a crash is a crash. Ideally people just run stress test alone because it's 'more stressful', but if running chrome at the same time causes a crash, you should be happy that it reveals instability where you might have gone on and assumed it was totally stable and then be pulling your hair out in a month when you are trying to tune a RAM overclock and nothing appears stable and then you are RMAing your RAM and the new ram still isn't stable and you are just going crazy...

Also, make sure you aren't getting WHEA errors. Look up the 'how i got out of wheaville' thread. WHEA errors are a big indicator of instability, and will crash streaming programs instantly or other intensive work.

Finally, make sure you know why you are stress testing. If all you do is game there's hardly a reason to stress test further than an hour or two. I run streaming with large audiences and GPGPU work so stability was extremely important to me.

Just bought haswell, going to delid today or tommorow, won't have the rest of the parts until a week or so. Where's the cheapest place to get CLU?

So here I am again, successfully delidded my i7-4770k a minute ago, ran some IntelBurnTest, and the results are every bit as spectacular as they were back when I delidded my i5-3570k! thumb.gif


Before:
4.3Ghz, Running at 1.15V:

Core 1: 83°C
Core 2: 82°C
Core 3: 79°C
Core 4: 69°C
Package: 83°C

After:
4.3Ghz, Running at 1.15V:

Core 1: 55°C
Core 2: 58°C
Core 3: 58°C
Core 4: 55°C
Package: 58°C

As you can see, temperatures evened out, and dropped 15-28°C across the board smile.gif
Ambients are slightly higher now than during initial test, about +2°C.

Screenshot:


I went from shocked and apalled at Haswell's temperatures, to being reasonably happy again smile.gif
When my custom loop and 900D arrive, I'll probably be sanding down the IHS again. I'd use the one from my 3570k, but that chip's been sold already.

Happy delidding, everyone! thumb.gif

Submit the info like the front page says and ill add you after work! thumb.gif

For a very modest 4.3GHz overclock:

Running at 1.15V:

Core 1: 83°C
Core 2: 82°C
Core 3: 79°C
Core 4: 69°C
Package: 83°C

Running at 1.2V:

Core 1: 89°C
Core 2: 89°C
Core 3: 86°C
Core 4: 75°C
Package: 90°C

Cooling: Corsair H100i, stock fans, running at 100%.
Voltage Control: Manual, CPU-Z reported no deviation during testing.
Tested with: IntelBurnTestV2

Screenies:




Needless to say, this has me somewhat disappointed...

As soon as my new syringes of CLP get here, it'll be off with his head!

Edit: Updated post with all relevant info I could think of, for future reference.

Here's the additional info, as requested:

OCN name: Leyaena
CPU: i7-4770k
on die-TIM: Coollaboratory Liquid Pro
ihs-TIM: Coollaboratory Liquid Pro
Mhz gained: None, so far.
OC after delid: 4.3Ghz.
Temp drops: 15-28°C, 25°C from hottest core to hottest core.
CPU-Z validation of max OC: I'm at work right now, but I will edit this in when I get back.

The reason I did my before-and-after testing at 4.3Ghz rather than 4.5 or higher is that before delidding, I couldn't get 4.5 stable at 1.2V straight away, and any higher than that caused me to run into major throtling issues.

Since people asked about more details/pictures of how I covered up the transistors with electrical tape, I really wish I had remembered to take a picture of it, but basically what I did was this:

- take a length of standard black electrical tape, slightly longer than the length of the transistors on the chip.
- cut it down to 1/3rd the width.
- pick the piece you like the most, I just used one of the side pieces with the straight(er) outer edge towards the chip.
- put it on there and apply VERY slight pressure to make it hold.
- apply clp/clu to the die
- put on the ihs again

basically for the picture, imagine the chip with a thin length of black tape right next to the die wink.gif

If there are any more questions, please don't hesitate to ask! smile.gif
