4720HQ lock at low clock speed, 3100mhz max when under load!!! Help needed

Hi guys,
I have just got a eurocom M5 Pro (P650SE base model) yesterday and after testing I found that the CPU (identified as i7 4720HQ in all custom and windows programs) is not performing to its max potential.
I am currently using Prema bios for this laptop downloaded from his site (1.03.04PM v.1) as shown in pic 1. In bios the clock rate is shown to be lock to 3400MHZ and not 3600MHZ, any reason for that?
When I boot up windows and open AiDA64, it also shown the clock at 3400MHZ but it fluctuated, once I only got 3200MHZ and once 3500MHZ.

A larger problem has occurred during stress testing like rendering HD video and prime95, according to XTU (1 Active core x36, 2 active core x35, 3 active core x34, 4 active core x34 as default) , Adia64 and CPUZ, the CPU never exceed 3100MHZ(x31) and most of the times it stayed at 3000MHZ(x30).
I have only used this laptop for 1 day and eveytime I use it is on higher performance with power plugged in.

I don't necessarily need overclocking but I just want to run at 3600MHZ at default(no manual tuning needed) as it should.

For some reason notebookreivew is acting on me, I am already frustrated enough I don't want to talk about the site but it's not letting me add attachment, not letting my add pictures and worst of all, I can't even login because it always redirect to the login page no matter what broswer I use (firefox IE) and what computer I use (both my desktop and my laptop)!!! but I've included everyting I know. If someone knows how to solve this please help me. If you require more information just let me know and I will have it for you

Thanks in advance!

E1: Thermal throttling in XTU is 0% CPU temperature avg 85 degrees C

 

The 4720hq is a 36/35/34/34 part than can be tweaked to 38/37/36/36 as a maximum. Windows usually uses more than one core so it will only very rarely run at single core speeds. Under stress testing you will run into your 47W tdp limit before clock limit. This is normal behaviour to keep it in spec (games will usually keep it near max speeds). You can overclock it by raising the TDP and multiplier if you need more speed.

 

1 - As meaker said, your CPU's 4-core turbo boost limit is 3.4GHz. 3.6GHz will only happen if only 1 core is in use. Under most gaming scenarios, 3.4GHz will hold consistently, as your CPU is not being properly stressed. The "max boost" is never marketed as being "single core only", even though it is the same way for desktops, and people don't bother researching how it actually works. In other words, "max boost" is a marketing tactic by manually leaving the 4-core boost out of the statement.
2 - Under stress testing, also as Meaker said, your CPU is not allowed enough power. It will draw well over 47W TDP under load, and may need a higher amperage allowance as well. The mobile CPUs are artificially limited in this way so that they will not overdraw the honestly limited power bricks that most notebooks come in, and also that cooling systems need not be designed to handle ~80W of TDP etc. The chips are basically the same as desktop chips; they can drink a LOT of power.
3 - You need to OC for it to hold at 3600MHz across 4 cores 24/7, however this may stress your 180W power brick a bit (assuming it works), and if it DOES work, the trend is that HQ chips do not usually hold OCs very well, even with power limit adjustments. You can try, however. If you are willing to get that to hold its load while under stress, I would suggest running intel XTU and setting the power limits to about 70W, and setting your amp allowance to about 100A from the 72 or 73 default. That shouldn't kill your power brick if you have a stock 970M.
4 - You probably need to make 5 posts first before you can do things like send private messages etc. It'll come in time, don't worry.

 

@meaker ok it might be running in 36/35/34/34 configuration but when I render and stress it doesn't go to x34 either, only to x31 peak value, how do I make it go higher?

 

@D2 Ultima
R1. Ok, I thought mobile chips behave the same as desktop chips
R2. I never thought power would be the limitation as I OC a lot on my desktop, but it does have more juice in the PSU and seeing it only needed 47W vs 130W makes me think it should eaily hold its speed
R3. Never thought about OCing on laptop other than gpu if I decide to play a few current games on there
R4. only 2 more away

Thanks for reply, you cleared a lot of facts for me, this is my first "gaming" laptop I thought everything would be the same on desktop but apperantly I'm way off.

 

They do behave the same... just that mobile chips have a very low power setting normally. If you stress them, they draw as much as the desktop chips will (see how the 4790K draws 88W power? Play BF4 with that; I bet it barely touches 60W load; run linpack, I bet it passes 100W); you just need to relax those power limits first. Most people don't realize this. If you want a little bit more info you can check the i7 CPU guide I have to get a basic idea of how laptop i7 CPUs work. Anything else you need, you can reply here and I'll help to the best of my ability.

Next, don't worry about it. NBR can get you up to speed quite quick. Everyone had their first at one point XD.

 

Ok I see, so the mobile chips suffer from less power, but I don't think I will be modifying anything, still want to use this laptop for a few years

I have one question about the GPU though, or the fan control more to say. I don't think OC hard on laptop will be something for me so while have full control of the GPU is nice, but I just want to know how to custom control the fan speed since when I run skydiver and firestrike it will go up to 78 degrees C, but when I OC +200 on core +150 on mem it only goes to 74 degrees C because the fan spins faster. the bios on there is 84.04.1F.00.BD. I tried also prema's vbios flash but it didn't change a thing...

It is the 3GB verion of the 970m

 

1 - opening up the power limits won't hurt your machine in any way. It'll just mean that you are allowing it (not TELLING it) to draw more from the PSU if needed. Your 970M is ~80W and your power brick is 180W; that's why I said 70W limit is good for you. 70W + 80W = 150W and 30W for the rest of the system. Should be fine, I think. Your power brick can go a bit above 180W for some length of time (not a full day though) so spiking above the limit won't hurt.

2 - Fn + 1 on a clevo will force fans to max. You can do this for the best cooling. Propping the machine up will also help if temps are your concern. Either way; unless you're basically a 88 degrees under load with spikes above that, you should be fine. 77-80 degrees is perfectly fine for laptop hardware. And desktop hardware too, despite what many will assume.

 

Yeah they way these chips work is they'll try to achieve the highest clock you can while staying within a certain power draw. If you are using all 4 cores they'll all be drawing powers leading to a reduced clock speed. On the other hand if you are running an application that isn't multi threaded and only using a single core, the others aren't really drawing power and the CPU will throttle up to give the best performance possible

 

Ok, thanks for the tip!

 

You could just start off bumping the tdp and seeing how you get on.

 

We checked it with another user in the owner's lounge. The chip doesn't draw any more power even if you relax the limits. He's stuck with that performance, unless a Prema BIOS changes things, which I haven't been able to get someone to test yet.
