Why is my Alienware 15 CPU throttling to 800 mhz?

Actually dell product development team had my R1 under observation for more than a month, so basically its the hardware fault, they couldn't fix things, undervolting helped some users, but that too only on cpu stress test, when both gpu and cpu kicks in somehow it throttled again, i had like more than 7 different mobos from dell, i personally tested all those undervolting, increasing amps etc.. nothing worked, even ive met the guy who codes DELL bios.. he tried with custom bios, after 2 months I'm getting my replacement R2, ill update you guys soon.. and regarding R1 i have nothing to say, u gotta fight against them, @Papusan knows exactly how many mails, calls, screenshots ive shared with dell / alienware reps.. atlast it paid..

 

Same thing happened to my system well, technician asked me to give online access, i straight away denied..

 

So guys, I have found a AW15r1 with a GPU Amplifier for $999. Should I not get it? It has a few months left on the warranty.

 

check if it throttles, if its a 970M gpu, then the price is good.. considering u get a free amplifier.. but be careful.. so many R1 machines have throttling problems.. check before u buy..

 

I had the R1 with the 970m its throttles as well I wouldn't get it , but if you can test the system before buying I would recommend running heaven and XTU simultaneously that will give a clear picture if it throttles or not.

 

thats exactly what i would say, because if the machine doesnt throttle after 1 hour of intense benchmakrs.. then sure its a breaking deal.. if it does then no point of buying it.. even with GA.. i think he should really wait.. save money and get a newer version or some other brand with new pascal gpu

 

Thanks guys. There is no way to check it as it is an eBay listing. I'm guessing even with a warranty that Dell does not acknowledge the throttling issues from what I've read on this thread.

Dag on shame. I have a guy going to sell me the AW15 r2 for $850 w/970m. I may go with that.

 

10x times better choice.. i mean alienware 15 r2 for that price..

 

They definitely acknowledge it. I started with a R2 and they gave me a R3 because of it

 

Honestly; i didnt read this text. I had the exact same issue. For me the "express charge" feature had burned the cable. Choking my pc to 800mhz. They replaced the cable and it worked fine.

 

i was interested in getting a 17 r2 , r3 or a 15 r1 or r2 just because the graphics amplifier but after reading this forum i will have to reconsider it , actually im afraid of getting any aw machine from now on, i know bga affects all manufacturers , but i havent heard these problems with asus or msi thus far . unfortunately getting a desktop lga laptop is way beyond my budget .

 

I've had my 17 r3 since release date, spend 8 hrs hard work daily, and most nights game several hours as well. Other than some hiccups with nvme drivers for my 950 pro, it's been flawless. My work issued precision 7710 has been sent in for repair to many times to count that work has just allowed me to use the alienware now.

if your 17 r3 is working fine then good for you . i wont risk spending money on neither because sellers dont have a clue if the machine throttles or not . i asked one seller on ebay , i pointed out this forum and he said he does not notices any lag during gameplay but he is not sure . i wish sellers where more knowledgeable about the stuff they sell

 

Still not quite sure what your asking. Lag could be from a lot of things, most often Internet speeds. As for throttling, Windows version, current installed drivers, current installed programs including programs that run in the background, Windows settings, program settings, nvidia drivers, game settings, hhd vs SSD and background usage of such.

Those are all things needed to know, while running some kind of system monitoring software such as hwinfo. While also monitoring system and ambient Temps.


You let the seller know all of this, and if he wants to spend hours trying to recreate how you will use it, and test it before hand, then props for finding a seller with nothing better to do with his time.

i used the word lag because it was the word he used , however i asked specifically about throttling, maybe he does not have a clue what im talking about , as i said before i pointed out this forum to the guy but i doubt he took the time to read it

 

OK, well my point kind of proven to myself. This is the 3rd time I've written this, first 2 on my pc which I has lagged, hung up, and crashes. (IE issue not pc issue)

But exact laptops in question, not general models.

Throttling.
Throttling in/on a machine is more dependent on Windows versions, firmware/drivers, back ground tasks, and installed software (which tends to bring hidden conflicts).
These are extremely hard to find and figure out, and almost always best fixed by fresh install of windows unless you have hours to days to tlsit down and figure out.

Sometimes, model specific, throttling is caused by firmware (most notably power delivery settings, but windows power setting can also throw this off). Example of this is if cpu is always defaulting to a common frequency, like 800 mhz. Something is telling the cpu to stay here. Could be Temps (easy to figure out) or it could be a driver for whatever reason is limiting this, could be a windows power setting. If it was hardware, it would be a power delivery issue, which can only be determined by ruling everything else out.
Ruling out firmware, are you on the latest update? If so, try reverting back or 2 and see if that helps.
Windows settings, check and make sure maximum power setting are enabled, machines plugged in, and with the appropriate power adapter. If I use the 180w adapter from my alienware on my precision, or my old 120w adapter on my alienware, the machine by default only allows my cpu to a certain frequency. This also happens a lot with aftermarket plugs.

Also take note, if using benchmarking or stress testing software, these are simulated and in no way shape or form going to represent real life circumstances. Both ends of this spectrum, you run prime and furmark, simulating 100% cpu and gpu load. There is no everyday sinereo this condition would ever be met. But your testing let's say maximum cooling capabilities. This gives "an idea" of what "could be". You run this and see throttling. Get mad. Well any program or game you could ever use, would be represented by this. Now opposite end of spectrum. Simulated workload. I could run prime and furmark or cinebench all day on my ROG 750, and it's pass all day without issue. But if I went and just rendered a movie (something I do often), CPU would hit 100C and throttle off/on nonstop.

Now back to your post and my reply. Any knowledgeable seller would see a request as to, if the laptop will throttle, as a days project to setup the laptop how you will specifically use it, and then test it. I do not know anybody willing to spend that much time on something with so many variables involved. And a un-knowledgable seller won't even know what your talking about. So, long story short, knowledgeable or not, your not going to get a good/reliable answer to your question. Your only and best option, to test it yourself, take advantage of buying it from a reputable seller who allows returns.

Hey guys,

Brand new Alienware 17 7820HK/32gb/1080.

If I run prime95 and furmark at the same time, the GPU goes to 70+ C and the CPU goes to 80-95 C and stabilizes around there.

If I leave it for 30 minutes or more doing this, it starts to throttle the CPU back to 800 mhz.

Is this normal? Should I be worried? Is prime95+furmark unrealistic?

 

Throttling down to 800MHz ain’t normal. Your Cpu thermal Throttle. Probably due TRIPOD. And stop using Furmark. You can kill your graphics. Rather test with Aida64 as this guide. Post results with pict.

 

The 15r2 and 17r3 models dont throttle only various 15r1s and 17r2s depending on the configurations.

 

any luck with the replacement?
