What video? Haven't seen it. I didn't delid mine because of the hassle with another expensive paste and IHS that moves. Can't go naked which would be the choice otherwise if I didn't have air cooling.
Linus and his bunch of goons videos are more of a comedy show, to laugh biggrin.gif

Prepare to laugh, and laugh hard.

Eh. He's using the stock cooler, which is probably the bottleneck anyways and not the TIM underneath the CPU. Even if heat can move faster from the die to the CPU cooler, it's just getting "stuck" in that CPU cooler anyways because it's not dissipating it that well.

And not even overclocked and guaranteed to be at stock volts.

And "Maker's Glue"? What did he say the TIM was? I've never heard of whatever brand he was using.

And, what a glob of paste he put on top of the IHS! Even if it is "consistent", I think it created an additional bottleneck.

Comedy, yes. Reliable or accurate? Far less likely.

The guy who runs silicone lottery is pretty chill so he'll look after you fine. thumb.gif

Oh, nice! Good find.

haha, yeah...I think there is far more evidence that shows large decreases in temperature.

Good vibes--I've heard nothing but good things about the guy.

Using stock cooler, test invalid right there biggrin.gif
Before: 70,70,60,63C on cores, ok so the stock TIM is so awesome that the diff between cores is 10C, right Intel master screw job.
Is he really going to cut it off? WTH, that's like 2006 right there tongue.gif
WTH is he putting on the die? Replacing one bad TIM with another bad TIM...

Man they really need to get their poo together or target a different audience, something more along the lines of a comedy show, or "how not to do ..."

I guess they've started working on it, this is the official LinusTechTips twitter:

Just delidded my 4770k using vice only method and sanded the heatspreader. I used coollaboratory pro between die and spreader and also on spreader on heatsink connection. I must admit it was abit scary and i made small dents on the corner of the heat spreader. My temps still went down +-15c and now they are more consistent, only 5c difference between coolest and hottest core. Before it was 12c, didn't matter how many times i reapplied the thermal paste between sink and spreader. Now running 4.7\4.5 on 1.35v temps hovering around 65c(im on water) stressed with x264 for 10hours so i call it stable.

Right?! With good cooling, the die TIM / spacing is a bottleneck! 15C is huge. You don't get that ROI really on any upgrade besides an entirely different CPU cooler.

Intel shipped the new i5-4670K! biggrin.gif Batch is 3408A992 which looks to be Costa Rica. It looks average to good, which is a big upgrade, haha, for me and my terribad 1.365V @ 4.5GHz chip!

I'll send it to get delidded this as soon as it comes in. Apparently, the guy who runs Silicon Lottery will bin it for you, too, to see what they could've gotten out of it.

Hi guys,


I've been trying to overclock my 4770K to 4.2 GHz, using the following guide as a basis:

http://www.simforums.com/forums/haswell-48ghz-on-air-building-a-haswell-system_topic46180.html

The author recommends, first of all, putting the OC through a one-hour OCCT:Linpack test w/ AVX enabled, and that's what I've been doing. I started with the following setup in the BIOS (Maximus VI Hero):

CPU CORE RATIO: PER CORE
1-CORE RATIO LIMIT: 42
2-CORE RATIO LIMIT: 42
3-CORE RATIO LIMIT: 42
4-CORE RATIO LIMIT: 42
MIN CPU CACHE: 39
MAX CPU CACHE: 39

CPU CORE VOLTAGE: MANUAL MODE
CORE VOLTAGE OVERRIDE: 1.16
CPU CACHE VOLTAGE: MANUAL MODE
CPU CACHE VOLTAGE OVERRIDE: 1.25
CPU SYSTEM AGENT OFFSET MODE SIGN: +
CPU SYSTEM AGENT VOLTAGE OFFSET: .200
CPU ANALOG I/O VOLTAGE OFFSET SIGN: +
CPU ANALOG I/O VOLTAGE OFFSET: .050
CPU DIGITAL I/O VOLTAGE OFFSET SIGN: +
CPU DIGITAL I/O VOLTAGE OFFSET: .100

SVID SUPPORT: AUTO
INITIAL CPU INPUT VOLTAGE: 1.82
EVENTUAL CPU INPUT VOLTAGE: 1.85

However, I've already had to raise VCore several times, and it still hasn't passed this test. First a BSOD as soon as I began the test, then another BSOD one minute in, then a crash three minutes in. I'm currently sitting at 1.21V, but it has also failed after 17min, this time giving me an error, without crashing. Besides that, core temps are already reaching 87ºC maximum.

Should I pursue this further or lower the clock to 4.1? This Linpack test w/ AVX is very stringent, and I don't feel comfortable keeping these dangerous temps on the CPU during one hour (although they seem to be normal with this test). What do you suggest that I do?

By the way, my cooler is an EK Predator 360 with 6 Vardars F4-120ER in push/pull, cooling both the CPU and a 980 Ti.

Thank you.

Overclock your cores first, then cache, the heat of your cpu will also cause instability so it would probably do you a great deal to delid it and get those temps down, 1.21v and 87c isn't great.

Uh why are you following an outdated guide instead of this one?

I strongly recommend not doing avx2 synthetics on a 4770k.
