Why is my Alienware 15 CPU throttling to 800 mhz?

Thankyou bro for trying to help us, everything is okay, but is it actually safe to change power limits, tdms, and voltage? I can't risk my cpu's health for that! Hence i am scared to try this man, bit i definitely want the highest power and turbo for long times!

 

if you want high power for long time, you have to try. It is save because no matter what you do, as soon as the cpu gets to hot it will do thermal throttling to prevent damage. If you undervolt the cpu will stay cooler for longer. save voltage for i7-4710hq is cpu core, cpu cache and intel gpu each -50mV. My one is 100%load stable at even -90mV, but that is may just a lucky cpu. However, set at first profile 1 for ac adapter and profile 4 for battery use (you do it in throttlestop options). than disconect battery and connect ac adapter. test the settings from my posted pictures for profile 1 with ac adapter.
IF the setting makes bluescreens (i don't think so) than disconect ac adapter, reboot with battery and try out profile 1 voltage with just -50mV. Have fun

It will need some trys to find your perfect voltage but it is worth it. My performance increased a lot and the temperatures droped 5 degrees under 100%load

PS it can be that your bios is telling the ac adapter to just use xyz watt. than you will have throttling because the laptop is unable to get the needed watt for max performance. YOU SOLVE THIS ISSUE WITH connect battery plus ac adapter. With this trick the Laptop use ac adapter and battery as a powersource

 

Bro, disabling EC is giving me some cpu spikes causing Cardiff in voice while gaming, but without EC , there is no fan control. Help me please!

 

I'm sorry, bud. I don't have a 15 or 17 to test things with. If the settings are not working, it is probably being blocked in the BIOS somehow.

 

How can I recreate this throttle?

 

Maybe try to run wprime and a graphic bench like unigine together.

 

What to do guys? why is this important thread suddenly abondoned by u guys?? what have u done? help me please, the thing is that after getting the 240w adapter, same bios a05 and even a00, the temps have increased so much and thermal throttling occurs(wow a new problem now) help me guys, this is such a big issue guys, yet without a final solution :/

 

I wish I could help, but I do not know what advice to provide since I do not have a machine like yours. If I knew what to tell you, I would do so in a heartbeat.

 

search the threads for undervolting or do a google search on the web. The European alienware forums are also a help.

 

I am dealing with this issue too. I want to ask you a question though, did you get power throttling on XTU when you use 180W&A05?

 

Not much you can do with this. Maybe you should change to a much better thermal grease yourself or get help from Dell support. Buy a tube IC7, Gelid extreme or Grizzly Kryonaut. The best option is to use Liquid ultra.

 

How can I recreate this. Anyone still experiencing this?

 

Heyy Bro, i wanted to ask that is the laptop stable till now? since it has been a lot of days since u got the 3rd replacement, whats the news? is there 800 mhz throttle?

One more question i wanted to ask, since u had problems only related to some parts, why did u ask for an entire laptop replacement? why didnt u just get the HDD , Screen or the motherboard replaced?

 

Just read through this thread this morning as I have started to consider picking up (most likely) an AW 17 for work purposes and was sad to read about the throttling issues. The use of Throttlestop reminds me of the days with my M11x-R2 that ran for years after (still does in my step daughters hands) with Throttlestop.

I noticed that one poster was running an AW 17 R2 with a 4980HQ processor, while the current AW 17 R3 is showing at best a 4870HQ processor (curious after Skylake). Do you folks think this was due in part to accommodate the 180 watt psu throttling situation, or just because they are ditching chips and were out of 4980HQs? Wondering now what the situation will be with the Skylake release...

I'd even consider the heft of an AW 18 IF I could get a QHD screen... and the MQ series chips, but alas nothing but 1080p.

 

well to be honest, like papusan mentioned, its the processor which is bad, I got my third replacement MOBO with 4720hq, which got same throttling issue, so I guess it depends on individual chips, my first and second one throttles to 1.8 to 2.6 on some intense gaming within 5mins, the latest refurb cpu throttles to 800mhz, with 3mins of intense gaming, really bad, no matter which psu I'm using and bios.. A06 with 240W psu.. nope.. " l will throttle " - 4720HQ aka the bga thug..

 

I undervolt heavily on the 6700HQ, and even then the CPU will drop to 800mhz for about a minute and then come back. Here is what happens what I can tell. lol as I just started to type this it throttled and the entire laptop gets crazy lagggggy. So anyways, throttlestop says it's being TDP throttled. My temp as I write this dropped from full load 65c to 40s and it's still at 800mhz. Then after a minute the TDP throttle is slowly lifted from 6w to 20w then to 45w after a full two minutes. During this time I am no where near 180w let alone 240w. My next theory is to see if HWinFo is causing this; maybe the EC seeing the fan not increasing causes it to TDP throttle the CPU (but why not the GPU???? beyond me) I have my fan tables set to max 3500RPM since they are SOOO DAMN LOUD. (love you Asus...) but my temps are never above 75c. And the throttling is over lol In my case, Throttle stop can't take over and bump the clocks back up as the BIOS (or the framework software) is TDP limiting it.

Full load voltage is way under a volt. Almost at .8v!

 

Which laptop? I have a AW17R3 and my wife has a AW15R2 and they both do not throttle at all.
I have tried some craziness to get it to throttle.

 

Maybe your CPU power settings are screwed up. The Alienware 17 and 18 with 4930MX run like a craptastic throttle-fest using Alienware's stock and preset OC BIOS settings.

Check in ThrottleStop and see what the Package and Primary Plane Power Limts are set to. (These are Core Current Limit and Processor Current Limit in XTU.) If they are too low the CPU will always throttle. Unlike voltage, you can max those out and the CPU will ignore any excess amps and watts that it doesn't need, so no need to worry about setting them too high. If you set 300 in all 4 boxes that should be more than enough.

 

I uninstalled the Intel dynamic thermal framework software and that has indeed stopped my throttling. It makes about 5 devices show up in the device manager as no driver installed. i dont care, I disabled them all and now I can't get the laptop to TDP throttle. That software must be looking at the PCH (that seems to run around 100c under light loads) and then cut back on the CPU TDP. We don't have tablets intel.... we have a freaking gaming laptop lol

6700hq only comes in the 15 R2 and 17R3.

 

Which Windows version are you on?
I would do a clean install of Windows. If that doesn't resolve the issue it may be a motherboard issue. As I mentioned before I have a 17R3 (same mobo) and my wife has a 15R2. We both do not have this issue. However we did have this issue when we had 15R1(s).

Windows 10, like I said uninstalling the intel thermal framework solved it for me. It's intel tech that does exactly what it's supposed to do.. for tablets lol cool the case of the tablet if a sensor somewhere else on the board gets too hot.

just my theory

 

That did not actually fix the underlying problem. It might help minimize the issues you were experiencing, but it's not actually fixed.

Look in the BIOS and see if there is an option for overclocking features to change cTDP to BIOS. If that option is available, with it disabled the machine will perform much better, all of the things in Device Manager that you disabled will go away (won't need to be disabled) and you won't need any Intel DTPF drivers. Using the cTDP option instead of BIOS option always sucks in my experience. Simply changing from cTDP to BIOS (if you have that option available) may instantly resolve everything for you.

What you discovered by removing the Intel DTPF drivers suggests that the CPU power settings may not be set up correctly. If you haven't already done so, try increasing the power limits I suggested. I realize you do not have a 4930MX CPU, but the point of my recommendation is your CPU (no matter which one) will not function correctly if the power limits are set too low.

 

Sorry I didn't understand. I have no such options sadly. I only know my info from Throttle Stop. Both Long term and short term are set to 96w for 72s which is the max for a mobile CPU. (unless they changed it for skylake) Used to have a 3840QM at 4.3 GHz on an Asus G46VR so it saddens me I have to do this much work to even get a stock CPU to perform correctly on newer hardware haha. I do a lot of Primegrid so my laptop sits all night at 100% gpu and CPU. Just like my trusty G46VR that 14 inch little laptop survived 4 years of that. this laptop can't even go one hour before acting dumb haha

Also trying to figure out how I can't get the idle power consumption to be 6w again. I now sit at 10 watts after a fresh install of Windows 10 lol

 

I would agree with Fox this isn't a fix since you are just disabling some hardware interfaces by uninstalling the driver...
Did you do a clean install of windows or did the pc come with W10? Sounds like either a driver is borked (i.e. dricer cleaning is needed)or the hardware is faulty. Both systems I have have the same board and do not do this at all.

Under what conditions is the system throttling? What should I do in attempts to recreate this?

Even try resetting the BIOS defaults if you haven't already tried that.

 

PCH temp around 100c under light loads is more like a faults with your Motherboard. Ask other what temp they have during light loads.

 

HWinFo claims that sensor is called the PCH. Now I'm doubting that now as it's current temp is 0.0c lol

 

Also i'm not the kinda guy that assumes a faulty motherboard right away. After disabling the thermal framework, no throttling all night long. Most people don't leave their laptops on all night with a full load so if it keeps surviving this week, I'll assume that's a permanent solution. At least the laptop isn't unstable, which then I would point my fingers to faulty hardware.

 

Well most users are able to install said driver and it works and it is causing adverse results on yours it could point to a hardware failure. After all drivers are software interfaces between the OS and the hardware.
However it could also point to something wrong with Windows / the drivers. Either way if I was in your situation I would try and figure out why this is happening and not just sweep it under the rug.
To each his own.

 

Yeah, A half baked solution will only hit back on you later the road. If most people haven't the problem then you need to figure out what's wrong.

 

Just noticed throttling in my 15 R1 during BO3 since last week, CPU throttles to 800mhz.

I play MP mostly so I haven't had the chance to test it during campaign but in order to trigger it the match has to be longer that 6 minutes and after that it will recover the normal speed after 2 minutes or so.

Never thought BO3 was that intense on the processor, Graphics card remains under 80°c.

Most settings are maxed out and with that I get steady 60fps (or used to).

Temps in my city have increased in the last month so I guess there's that but I wonder if I should contact Dell for warranty since it ends may 31.

What u guys think?, should I call Dell?, do they even care about this problem at all?

 

Not acceptable. @VICKYGAMEBOY can give you some advice. As he had the same problem and same machine.

 

I have def been logging this situation. A full night of full load, tonight will be with the software installed.

 

I had a 15R1 and it throttled as discussed...
For months I had off and on throttling. After A06 it got much better and in some cases stopped.
Months later either because of driver updates or perhaps game engine updates some of the throttling started happening again in situations that it was not happening since A06.
Because I kept seeing this I kept showing Dellienware. Even getting in touch with the engineering teams.

Finally...
I bought a 17R3 and no matter what I have thrown at it the throttling does not happen. (and I have tried some crazy simultaneous stuff)
So after some testing and realizing that the 15R1 / 17R2 was basically crippled and flawed.
Once I saw this I showed Dell and they gave me a refund for the 15R1 and the extra 3 year warranty I added on 6 months after purchase.
Mind you this refund came 1 year after the original purchase.

Bottom Line: The 15R1 / 17R2 were flawed in many ways. I suspect that they realized that there was a design flaw and bandaided it on the 15R1/17R2 and then fixed it on the 15R2/17R3.
Which makes total sense as this industry simply moves so fast for it to be cost effective to redesign hardware should an actual hardware design flaw be discovered.
If the fix was as simple as a BIOS fix then it would have been done by now.

 

Thanks for the comment, I will contact dell's support tomorrow morning to see if I they can do something before my warranty expires. Oddly, I'm experiencing exactly what you described, BO3 was running perfectly fine until last week's update, then the throttling started. And yes, it goes on and off, today I've been playing BO3 for about 2 hours and not a single issue

I highly doubt they'd react the same way as you with me (especially since my warranty expires in about 2 weeks), I'm not greedy to ask for a new 15 R2, I just want mine working correctly.

 

If not. Extend the warranty and hope that everything gets worse, so you get a replacement. Maybe brick the laptop with several bios flash later the road!!

 

Its not greedy to ask for a 15R2. The performance is identical and it resolves a major crippling design flaw with the R1. Its greedy of them not to swap it out for you. You had a system for sometime now that has been flawed!
IMHO

However it will take some effort...
Usually only the Executive Customer Support Team will really care about a situation like this.
To get in touch with them you have to complain with a place like the BBB or something.
You might be able to just get an exchange via tech support but you still run the risk of there being a R1 still in the refurb inventory. If that happens then you are back at square one with a throttling system.

 

not an option, another year its about $400 here.

 

Went through this with the R2. It takes 3 failed attempts at fixing to get a new system

 

Not always. Ask @VICKYGAMEBOY

 

On my particular machine, having the Thermal Framework software uninstalled, stops my random 800mhz throttling. I'm on BIOS 1.2.12 with a 180w adapter.

For reference I have a 6700hq and a 970m @ 1337Mhz

 

Thought Skylake models didn't have that issue.

 

His situation seems to be a hardware problem. It resolves when he uninstalls a driver.

I have a 17R3 and a 15R2 and I have ran some crazy things at the same time... Intel Tuning Utility + Heaven.... Prime95 and Furmark ... Crazy things all at the same time. Things that would 100% trigger throttling on the 15R1.
They all DO NOT throttle this PC.

 

Y'all wanna hear a joke?

*Dell support technician controls my system remotely to verify any issues
*Technician starts a system restore
*Laptop stuck in boot loop...

 

Skylake models still have a configurabe down tdp (35W) that manufactures can use to throttle the processor for any reason they want

 

And make the Crap even more crippled? + A lot of other solution in Ec for crippling the performance ever further down!! Very important if the laptop design will be further slimmed and the cooling design and capacity will automatically be worse.

 

Yea, the author for throttle stop made me aware of this. He said it is possible to stop this by going in the tpl window, check tdp level control, make sure that is set to zero, and check the lock box. Maybe it'll work maybe it wont

 

So I was told by dell support that the next thing to do is to reset my system to factory settings (aka: delete all ur stuff and re-install windows and drivers, ugh..), I'm going to be doing that within the next 2 days and I'll report back after all has been said and done. Such a headache just to make them understand what the problem is.

 

Skylake is amazing.... after solving my throttling problem. Im working on undervolting. /offtopic.





yes the CPU is idling at .3 watts lol

Stable, LinX for 9 hours. Around 135glops

 

thats pretty good
