Any GT80 Titan or GT72 owners WITH the i7-4980HQ, help me out

Hello. I'll be rather blunt. I want to test the 4980HQ CPU's overclocking, TDP limit, current limit, and voltage limit potentials.

The GT72 and GT80 Titan laptops are among the only ones on the market that've had enough love for someone to actually own one, and I've already had users test the 4710HQ and 4720HQ chips for me already.

Basically, the point is that the HQ line appears to be TERRIBLE at increasing TDP limits, Current limits and possibly even Voltage limits. The options are available to tune in intel XTU, however adjusting the sliders does absolutely nothing.

Can anyone with either of these machines reply here and basically be my guinea pig so I can put proper information in the mobile i7 CPU guide in my signature?

In general, I need you to run a couple stress tests/benches like Intel's stress test or Linpack or something. In general, I need to see you drawing above your short power turbo boost max of 57W and not dropping overclocked values on your CPU under load. Some examples I have are below; please use HWiNFO in "sensors only" mode to check for TDP and clock speed per core. I'll give two image examples below of my CPU having a maximum draw of well over the stock TDP (check the maximum column in HWiNFO for the Linpack bench as I don't run the screenshot program during its bench):

If you lose clock speeds or get otherwise limited, please let me know. It helps to set your minimum processor state in windows power settings to "100%". I believe using the default "high performance" plan does this automatically.

 

Nobody? At all?

 

Are you needing these results inside the short turbo boost time window?

 

GTVEVO, I think you're the perfect person for this task.

Selfishly, the results of this test will be very useful for me in deciding what unit to buy

 

I need to know if the CPU itself is capable of going beyond its inborne turbo power/current limits. For example: with an i7-4720HQ I could set the power limits to say... 100W, and the current limit to 100A, then run something like Linpack. It won't ever draw beyond 57W which is its default turbo limits, whereas you can see that my 3.5GHz (stock) 4800MQ can pull 80W in the same scenario. Because of this, it throttles under heavy load where it should not normally throttle.

I wanted to know if the 4980HQ suffers from this issue, or if relaxing its power limits etc (for overclocking as well; as it's allowed to hit 4.2GHz on all 4 cores) is possible. If you can test for me, please do. For Linpack, you want to set linpack to 4 threads, and use task manager to set its affinity to only 4 cores. I suggest using max fans for this. If you are unable to increase the power limits a lot, it will not pull enough power from your system and begin to downclock severely. This is why I want to see what the max power draw is.

As for if it needs to be within the turbo boost power time window, it needs to be able to draw the excess load 24/7 (or it would be fairly useless in playing a game like BF4 in hour-long conquest large matches, etc) and the CPU'd begin to downclock after just a couple minutes with the max slider of 128 seconds for turbo boost short power max. Also, please set the short power max and the regular power limit to the same for this test. I'll show you what my XTU looks like for reference:

With the GT80 in XTU the turbo boost time window is completely disabled so you can not alter it, the power output for short and max is set to 200 w default. It will pull more than the capped 57w but only during the turbo window for the most part. As for BF4 I have played this game and the CPU doesn't come close to maxing out so. I have logged FarCry 4 which is more taxing that BF4 and no power throttling happens at any point. Below are images of a log I just ran showing power around 70w, hopefully this helps.

 

XTU image would not post so below is a link.

That's good to see. So in gaming sessions etc you can keep say... 4GHz 24/7?

 

Its hard to say exactly what you are asking because the process clocks up and down in small bits during BF4 but not in the result of power limit or power throttle because cpu utlization is 25-35% in a large conquest game with all players 64 and all settings on max. It will run this without even breathing hard so for example at stock clocks it would go from 3.7 to 3.8 on all cores the entire game. Hopefully this helps. I have never tried to run 4ghz in bf4 but in Far Cry 4 its perfect with no issues.

 

Do you mind unlocking your FPS from 60 in BF4 and attempting to run it on ultra at 4GHz and checking what your CPU does? You will likely need max fans for this, mind you. The higher the FPS the more it needs to work.

 

Ok I ran it without vsync and it would throttle back to the 47w after a few min even though cpu usage was between 50-70% at prob 150fps average so it would not hold in this case.

 

Okay, so while it draws extra power for the turbo boost window, it will not hold it 24/7 like the MQ chips. Good to know, I'll properly update my mobile i7 guide with the information now.

 

D2 Ultima - I read your mobile CPU guide. Thanks - very enlightening.

In your opinion - is it worth the extra $400 to go to the "extreme" CPU in the GT80 Titan SLI - with the understanding that you now have RE: the limitations?

 

I'm not even sure that the GT80 comes with an XM CPU. The top model only has a 4980HQ.

 

Sorry - that's what I was referring to. Hence the quotes. I do not believe there is an XM Haswell CPU?

 

There is, but it's only socketed and MSi does not offer them with the GT80.

 

Yes, what mobius said is correct. Honestly, I can't say. I think it performs a bit better than the 4720HQ, but... I don't know if it's $400 worth. To be quite honest, I would quicker tell someone to get the P377SM-A and use the P370EM CPU and slave GPU heatsinks and just overclock your damn life away, honestly.

 

Passmark rated the 4980HQ as being just slightly slower than a 4930XM

 

Good for passmark... I've already determined that the HQ chips don't hold their OCs beyond a couple minutes, and the 47xxHQ chips don't do it at all apparently. A 4930MX in a proper machine will hold its clocks 24/7 once set correctly. Just like my CPU holds 3.8GHz all the time (I took off 3.9GHz because it uses too much power with my 780Ms to stream)

 

I run 4.1GHz on the 4980HQ, it seems stable in the games I tested and throughout benchmarks. Was never able to get stability at 4.2Ghz, but it is extremely stable at 4Ghz ; which is usually it's ideal average peak zone that it maintains. I have to take manual fan control though when overclocking, gets to 85*C-91*C max that I've seen so far.

 

I have a 17r2 with the 4980 but I don't have it with me at this time, but I do love it dearly.

My gt72 has a mere 5700 cpu and I can totally tell the difference in fps between the two

 

My 4720HQ caps at around 58.9watts with cinebench. Since my multipliers are locked, I can't get any higher.

Turbo window is not editable as it is, and without a doubt you will not be able to run above the 47w TDP limit if you surpass it. Your max stable would be around 3.3 - 3.5Ghz depending on the 100% type of load.

I am working hard on figuring out how to unlock the time window. I will have to mess with the EC. The GT80 by itself does not seem to have any particular lock besides the 47W TDP regulation.

 

Unlocking the time window prob wont help as I learned the gt80 itself would allow it but the processor doesn't care it ignores and still throttles the pl1 time.
