Haswell Temp Readings

[allenk09]

I just got my 4770k today and I can't seem to get an accurate temperature reading from anything. I look in the bios, it's 51C at idle, stock 3.5Ghz (seems high?) atfter reseating the heatsink and reapplying paste three times to make sure I wasn't doing anything wrong. Speedfan tells me the cores are at 19C each, and the lid is 43C or 34C. Hwmonitor tells me completely different things.

Anyone have an accurate temperature reading program for the Haswells?

Bios seems correct. Haswell temps are higher than previous gens.

Wow. On my Hyper 212 Evo too. I just came from AMD and would see 26C idle all day long. Crazy.

Yes, Anything that tells you the PECI value directly like CoreTemp or RealTemp. Switch to Distance to TJMax and never have to worry about if your temps are legit or not.

You can download the Haswell reviewer's kit here. Among other things, it has CPU-Z 1.64.2, which displays the correct Vcore (unlike all the <= 0.8V screenshots using 1.64.0) :

Hmm.....was your AMD

a Phenom X4 9850 BE processor from way back when. It had fairly slow DDR2 800 Mhz RAM but I have been using it religiously for about the last 5 years. I've been waiting to strike and I chose now to pull the trigger. No regrets.

Real Temp gives me ~27C on the 4 cores @ 23C ambient.

Sound right?

Edit: Wow, with the lower level power my entire computer is pulling 88W from the wall on the Kill-A-Watt.

sounds much better for idle, how about load?

AMD's processors measure temperature in a completely different manner. They are not comparable in the slightest.

 

[tweakboy]

Use core temp and put her on full load 100 percent for 5 minutes look at the temps. gl

Will post some load results tomorrow!

Monitor and everything? Nice!

What's the difference exactly? With my Phenom II, the max temp was 62C I believe, and mine became flaky at ~59C (using a crappy cooler). I got a Zalman cooler and got it down to 54C overclocked and it was nice and stable.

With Intel, I've read that anything under 80C is fine

 

[Ares202]

my I5-4670K (stock settings) with Corsair H50 cooler

ambient room temp 24C

idle:33c
load:48c (~1 hour BF3)

 

[Jamil20]

My 4670K idles around 38C and load is 65-70, and Prime95 is 90+. This is on an H60 cooler.

Stock cooler was 50-60C idle, it was terrible.

Is this normal?

Edit:
This is on stock clock

Sounds high. I get around ~35C idle, ~75C with Linpack. My 3570 was 40 and 80.

4,2 Ghz Idle: 30C

4.2Ghz Load:

Hyper 212 Evo with 2 fans push/pull, Arctic Silver paste I7 4770k, G1 Sniper 5. Ambient room temp: 23C

Vcore 1.150. Anything above 1.2V gets really hot and the 212 can't keep up. I was going for 4.4Ghz, but I couldn't get stable under 1.2V

Time to delid?

haswell has issues... so far listed by people i trust..

1. VRMs are now on the cpu..VRM's are voltage regulators... they heat up... on the board they were mosfets... u remember me tooting about having solid mosfets for high level overclocking....

2. The IHS was not caibrated properly with the node shrink.
This causes a gap between the IHS and node.
The cpu is also shown to not be soldered... so the IHS is not as good as the intel metal solder used in the earilier gens.


In short.. u got a cpu which heats up more then the previous gen at 5-10% IPC.
Totally not acceptable in the enterprise sector which is why the enterprise sector doesnt get this cpu.

The guys at intel knew this... its there attempt to crush the low end overclockers and limit what they can do.
And yes i consider all desktop line low end now.... LGA1155 / LGA1150 / LGA11xx Entire...

Intel made it clear on the X58, and X79 that enterprise will mesh into high end overclockers...
LGA1366 / LGA2011 / LGA20XX whatever they decide to come out..


Incase u guys are also wondering... the ONLY reason why we got a new board is because of the VRM's on the cpu.
Yet the VRM's on the cpu is causing havok with heat issues.. but intel doesnt care... they view it as acceptable... because it will limit your overclocking...

Why wouldnt the enterprise buy it? It reduces TCO more than any other solution. It got overall lower power consumption than previous, performance/watt is up. Platform complexity reduced.

If the CPU is 70C, 80C or 85C doesnt matter when the tjmax is 100C.

I am sure we could all agree it could be better at x, y, z. But its still better than previous.

Makes me wonder if my h100 is compatible with haswell/socket 1150

It should be. Same mounting holes etc as LGA1155.

Intel has said they will not release it for the full bloated enterprise sector.

Having chips that heat up more can bring a blade system which has boards stacked more problems.
The fans would also need to be ramped higher which also can also bring more problems..
Its not a IT solution win to go on haswell if this is what were seeing.

 

[WhoBeDaPlaya]

All chips from Microcenter with the same batch # (L307B239, which is all they seem to have).
All the chips below were OCed with Speedstep disabled, fixed / non-adaptive Vcore, automatic/default voltages (except Vcore), DDR3 1866, 3.9GHz uncore and 100 - 101MHz BCLK.
Voltages reported are values under IBT load. No memtest86+ errors. Considered stable if it makes it through 100 passes of IBT (will follow up with 24 hour Prime95 runs later).

Chip 1 : 4.55GHz 1.24V (CPU-Z), 1.247V (measured)
Chip 2 : 4.55GHz 1.241V (CPU-Z), 1.249V (measured)
Chip 3 : 4.6GHz 1.25V (CPU-Z), 1.256V (measured)
Chip 4 : 4.35GHz 1.242V (CPU-Z), 1.253V (measured)

Makes me wonder if my h100 is compatible with haswell/socket 1150

No worries. Same mounting hole config as 1155.

So we are not talking desktop chips? Single socket Xeons like this?

I can assure you that you can find Haswell Xeons in blades soon, if not already.

Cooling is not a problem either. Servers already contain jet fans that can run up to 15000rpm.
