Is something wrong with my Haswell chip?

Trolling, really?

I think he's referring to that dude taht is a water cooling mod

and imo if anyone who games is going to stability test, they ought to take more consideration into testing stability with the games they play rather than Prime95, with these latest gen chips.. i gave up on Prime95 yrs ago..

A bit off topic, but what are your general impressions of the Dark Knight? A decent little budget cooler?

What cpu cooler are you using.

From another thread:

There are a lot of variables here...

TIM used? I'm using Liquid Pro.

Fixed or Adaptive?

Ambient? Mine is currently around 72F.

Fans used? Fan speed? Mine is set to auto, it's most likely at 100% on load.

Reported vcore 1.288v

Crap forgot the snip in the sticky note, second is fixed, -18mv offset, 178w load, actual vcore according to software 1.2v

I asked Balla to run Prime95 after posting a result from the HardOCP forum of another retail 4670K. H110 vs Dark Knight so unless the Hardforum member really messed up his installation Balla's chip wins the matchup.


"My cooler is a H110. All were done on prime95 with Real Temp 3.7.

Here it goes:

Stock Idle -> 28C
Stock Load -> 54C
4.2Ghz @ 1.2v Idle -> 36C
4.2Ghz @ 1.2v Load -> 75C"

I think so, though I could be getting help from my chip vs what others are reporting.

For my needs it's great, all the way to 4.7GHz so far tested in Crysis 3 even with load reaching into the 8x% range it's still in the 6xC range. I could probably drive it even higher at these speeds but I need to use vsync with my 7950's otherwise my stomach will desync.

I've only owned two air coolers in the last 10 years, the Zalman 9600 and this, I like the DK2 more.

I like it's aesthetics, the all black is nice. The fan gets audible at full speed, but not as bad as video cards.

The mounting isn't perfect, you should put the fan on first, but if you do that it's not an easy task to get into the bolts to latch it down. Getting it tightened up then putting on the fan is easier but that's no picnic neither since the fan attaches to the fins and they're not exactly sturdy.

Overall I'm pleased with it, it doesn't hold a candle to my custom water loop but I think that should have probably gone without saying.

Balla that hardware deserves a nice case. What case are you putting that in? Congrats on the chip, you lucky mofo 🙂

Thanks, I haven't used a case in awhile always preferred open bench and still do.

Our cats and my kid scare me though, not sure what case I will get, but black or red would make sense considering the board and cooler will match that once the corsair fans I ordered come in.

I wonder if I should get a new cooler. My q9550 has an arctic freezer 7 on it.. wondering if I should just transfer it or grab a new one when I get my 4670

So your not going the custom water route again? How well is crysis 3 running? And at what settings? I imagine pretty good 😀 I am seeing low 70's @ 4.8 with my 3570K while playing crysis 3 (90's in P95 and LinX). I am thinking about going with a better CPU cooler though, the H60 is not that great. Even with two corsair sp fans.

There is nothing wrong with your chip, Balla. I've built 3 PCs with such parts:

1) Z87-PRO
2) 4770k
3) 212 Evo
4) Kingston 1600 DDR3L (2 or4)x8GB (KHX16LC10X3K2/16X)

Out of 3, 1 was complete dud, requiring ballistic voltage to go over 4.3 (1.3+), would require Jesus juice to cool . The other 2 are like your chip, doing 4.5-4.8 with 1.17-1.18 fixed voltage. Here's what I've found by playing with the Asus Z87-PRO and 4770k:

1) Fixed voltage is the way to go, chip is stable with 1.1x, but with Asus adaptive or offset when AVX load comes and bumps voltage to 1.25+, temps go north - obviously 212 Evo can't keep up. The difference in power between 1.18 fixed and non fixed is maybe a watt or two @ 800mhz, nothing to write home about.
2) Z87-PRO has some pecularities in the way they do auto tuning of uncore. If left on auto it always ran uncore @3.9Ghz and did not drop voltage or multi on idle. Voltage is also constant when overclocking, and for example on 4.5 uncore it was set to 1.3V.
3) So for uncore tuning it is best to set low multi to 8, high multi to highest you can run without ridiculous voltage, the chip in PC i've kept can do 4.5 @ 1.23V instead of 1.305 auto was suggesting. The fun thing is uncore and it's voltage has sizeable impact on thermals, but performance difference is tiny at best ( i did not notice any perf spike when running it same speed as core ). I've tried to manually run @3.X and undervolting on dud CPU, but it was of little help with thermals as they were probably dominated by core voltages.
4) With that cheapo kit i have found that it is hard to overclock memory AND overclock uncore and cpu at same time. Out of 2 better chips just one i've kept could do 32GB with 4 sticks and 1T + 1866.. Mem voltage, timing tweaking did not help much either - this is area i need to still master.

Now fun part is over, and thermals part starts:
1) Given right voltage for vcore/uncore 4770k will run without crashing. Throtling or not, it stays stable. The fun fact about throtling is that for example if you run Linx and your CPU starts to throttle and apps report throttling in 10%+ department - you will be hard pressed to find difference in Linx results, same 135GFlops +-1-2. I can live with throttling like that 🙂
2) 212 Evo can't take more than 1.16-1.18V without throttling @4.5Ghz and up. It can do 1.15 4.4Ghz fine.
3) Prime, Linx AVX and Aida with just fpu selected are like Furmark GPU power virus but for CPUs, you won't see such wattages and temps with any other program and game. There is 40C delta with Winrar benchmark, 30C delta with Crysis 3.
4) Lack of chip heat spreader quality is epic. All 3 chips have core temp difference of 10-12C with Linx load between coolest and hottest core.
5) End result of thermals is that if you don't mind throttling under Linx, you can run 4.6-4.7 perfectly stable @1.18V on those two chips.

So to sum it all - Haswell is a nice chip, as long as you win in chip selection lottery and so far i like the odds - 2/3 can do 4.5+ with sub 1.2 voltage stable on any load, but throttling under Prime/Linx. Any real world load is sub 60C with $30 cooler (and for purists 4.4 @1.15 will not go over 90C).
