I think this is going to become a bigger issue. The tdp is so low on these chips that I never see anything more than 2.5ghz base clocks while gaming intensely. All the MQ chips I had in the past did not have this issue. If we can get more people to monitor the cpu clocks during heavy GAMING, and report back the results, maybe we can get this on Dells radar, even though this is Intel's fault.

if everyone looks at my log below, you will see that as soon as the cpu hits 47 watts, it throttles back down to 2.5ghz for the entire gaming session. This was taken during crysis 3, look at the bold text for clock-speed and power usage right next to it

The processor should go up to a maximum turbo boost again when power usage is low. Intel has in its specifications 1.20 x TDP in short power max. Your processor stops just over TDP of 47W. Dell to blame..
Have you seen how high cpu package power(watt)go in Hwinfo under Wprime 1024 benchmark tests? Throttled processor in such a test?Last edited: Mar 14, 2015 -
TDP is the maximum amount of heat the system should be able to dissipate under standard heavy load (non synthetic) conditions. So basically once the chip exceeds TDP, Dell (or intel for that matter) can no longer guarantee that the system will be able to effectively dissipate the heat generated by that CPU so it declocks it.
Now in the good ole days TDP used to be measured at maximum power draw...but Intel changed that, then decided to go with their stupid SDP, then went back to TDP...and Haswell really really struggles to reach its TDP targets when you compare it to Ivy Bridge even though Intel claimed 50% less power! The other problem with Haswell is it's built in thermal throttling is far more aggressive and when you combine that with the thermal throttling from Dell, it just makes things worse.
The problem isn't only with Dell, yes they did some stupid **** but part of the problem lies with Intel too. You have to remember that Intel has basically started to slowly stop caring about the high end pc enthusiast market.
Look at all the new processors from Intel, what major breakthroughs have they announced? It's all low power, small chips, high performance from mobile / fanless chips etc. When was the last time you saw them go LOOK AT THE OVERCLOCKING POTENTIAL FROM OUR 8 CORE CPU. Intel today is more focused on mobile because they're losing a ton of ground to ARM. And since there's nobody to compete against in the high end segment (because lets face it, AMD is no longer what it used to be and the gap between them and Intel at the high end is massive) they don't give a **** about it. They've killed overclocking, they've killed LGA, and essentially the writing is on the wall for us pc gamers.Last edited: Mar 14, 2015Papusan likes this. -

Its not the maximum power the CPU can draw. And that's the problem with it and especially with haswell.Papusan likes this. -
I do not think I've seen such a processor throttle problem on an AW high end gaming laptop earlier. This test is from the previous model with equivalent processor(i7-4700mq). It manages to keep a higher clock speed than the processor that sits in AW 17r2 tested in the thread here. Try a similar benchmark for the new AW 17. This cpu in AW 17R1 can at least keep up TDP of 47W.

Dell has some funky thermal settings in the bios, and it looks like A02 is causing the CPU to run 5-10C hotter than A00, which could cause the CPU to hit its thermal throttling too soon. And the thermal throttling is an issue with all haswell CPUs.
If haswell didn't have such aggressive thermal throttling you might not see this issue even with a funky bios. And if dell didn't have a funky bios you might not see this issue either.Papusan likes this. -

How can I create such a log file?
Thanks. -

OK I tested my Notebook.
While playing Company of Heroes 2 the clock speed on all four cores was 3300Mhz and that didn´t change at any time. But the tdp was only 22W at max, so maybe this game doesn´t stress the CPU hard enough. -

Now you throw in a funky bios like the ones the new AW15 and 17 have, it'll only make the problem worse. -

I've been reading on this forum for some time now and I'm a bit confused.
Actually I don't know what to think about my new 17 R2.
People write about "funky Dell BIOS" and messed up TDP limits.
Are the other Gaming Notebooks like MSI GT72 performing better?Papusan likes this. -

I had a Clevo once and I'll never ever buy that plastic junk again.
And I don't want to upgrade at all. When new hardware is released, I'll buy a fresh notebook.
I just wanted to know, if the Alienware 17 R2 is "underperforming" compared to similar notebooks. -
-
Well, the GTX 980M in the Asus G751 is factory overclocked 5%.
Benchmark results of a MSI GT 72 seem to be similar to the AW17 R2.bnosam likes this. -

I've got the 4710HQ and GTX 980M, 16 GB RAM, 256 GB SSD, 1 TB HDD, 240W PSU, First BIOS.

The conspiracy theorist in me wants to believe these machines downclock so poorly because they're built to be used with some sort of external cash grab that 'overclocks them for sweet awesome enhanced full throttle gaming experiences, duuuuuude!' -
I did some more tests with my notebook and it didn't throttle down to the base clock speed at any time.
I ran Prime 95, which causes constant 100% CPU load and the clocks went down to 2800 Mhz for a short time. The CPU was at over 47 Watts several times and the core clocks went up to over 3000 Mhz again.
See
AFAIK Prime 95 stresses the CPU more than any game. -
I've run benchmarks with 3D Mark (winning that damn Brawn achievement), Unigine's 'Heaven', Prime 95, and wPrime (1024m, 8 threads) and my CPU always drops to around 3200/3300 Mhz.
Doesn't seem to matter what I run, actually. Even less demanding games cause the same dip. I presume it doesn't take much to hit the 47 watts to cause this throttling. -
Well, in your case that's a bit disapointing.
I'm actually quite happy with my results.
The 4710HQ in my AW17 R2 behaves exactly like the 4710HQ in an Asus G751. -
Your results are excellent.
Realistically the 4710HQ is performing on par with the 4980HQ due to the TDP perhaps being too low. Of course, this is presuming mine is not a lemon and is actually performing 'correctly.' -

My issue lies within that, if the 4710HQ is riding around 3.2/3.3 Ghz per core under load, and so is my 4980HQ... why did I spend the extra money?
Oh yeah. Graphics Amplifier. Probably the only way I'll see that difference. -

In fact, I'm glad you've told me this. I'm now convinced that there must be an issue with my unit. I'm just not smart enough to diagnose it, and AW Tech Support just tells me it 'falls within their test bench parameters.'
I'm considering another unit now, knowing yours is performing as I expected mine to. Maybe I won't be unlucky again. -

AW17R2 w/ 970m. Fairly pleased with the results.

Min and Max temps while running benchmark. Runs pretty hot. I'm considering if I should give repaste a try.
Considering as in, I already have the ICD in hand. The only thing holding me back is work and my new copy of FFXIV.

So, I asked this question a while back, but looking over more benchmarks today from the Clevo P650SG, it bears asking again.
Clevo P650SG
GTX 980M
i7-4720HQ
180W PSU
Firestrike: 8215
3DMARK11: P10706
I'm still baffled as to how the Clevo can reach those scores on a stock 980M clock using a 180W PSU, given the issues with the AW models.
Here are the O/C results from the same machine (+125MHz, 5600MHz VRAM)
Firestrike: 8996
3DMARK11: P11468 -

Just letting you guys know the new Nvidia driver is out and overclocking has returned

I just ran Firestrike on my AW17 R2 and I have a higher score than that Clevo.
I got a Firestrike Score of 8308 with stock clocks and the 4710HQ.Papusan likes this. -
