Aurora R13, CPU throttling, power limit exceeding

Running Cinebench R23 there's a few issues I'm having.

Multi-Core

  1. It never goes beyond 4.8GHz
  2. All cores reach Core Power Limit Exceeded limits and is power limit throttled down to 4.4GHz.
  3. Computer constantly lowers power delivery from 232w down to 170w throughout the 10 min Cinebench R23 multi-core test.
  4. This happens with OC disabled in BIOS and enabled testing CL1 and CL2.

Single-Core

Didn't have any problems with single core.

I mean what is the point in overclocking when it doesn’t even reach the standard turbo boost lol. This is abysmal. I had had mine a couple months now, and awaiting a response for a full refund. It really shows how little they care about their customers. They cant make it fit for purpose unless the some how mod with a new cooler.

I think no matter what is said, at the end of the day, dell is a billion dollar company and basicly they have no excuse. Its just greed. When much smaller companies and niche ones can produce something that does what it says on the tin is very telling. Put a i9 in a machine that does what's it suppose to do for heavens sake. Would you put a Ferrari engine in a ford design n say its the best engine, but the car cant use it. You cant take peoples hard earned money and look the other way i'm afraid, and say nothing. I will have my r13 refunded even. Saying all that I have been a AW fanboy for along time. I love my area 51 r2 to this day. I upgraded her with a i7 6950x n 3090 n still what a machine. Aurora r6, x51 all loved them. I got those new wireless trimode headphones, fab. This is the first time I feel really let down massively.

These people at Dell support just do not listen that the i9 is incapable of functioning by intel standards because of inept engineers. I've sent them the data, and online info n vids, and they says it's a faulty lol. No it's just a bad design! my r13 is only capable of holding a 160 watt tdp after a couple of minutes from around 225 watt, with a clock of around 4.4ghz when the throttling comes into place as the chip nears tjmax. intel specs are upto 5.2ghz and a max turbo tdp of 241 watts. The r13 can't get anywhere near it with the way its been implemented.

I would be interesting to see the TDP of someone who has a lower end CPU installed in it, to see if it can stay above the 160 Watts for extended periods of time.

This power behavior was observed in the video part #2, I think it was after 50 seconds.

 

It might very well be a limitation of the VRM section. We will have to wait for the official response on what is happening here.

My i7-9700K / R9 has hardly ever seen 4.4ghz while gaming/load and it’s stable for hours @ 4.7-4.8 ghz. And I totally agree with you and other with the R13 and 12900,  it’s slick what they did to compensate the failure but terrible and unprofessional at the same time

I’m not being funny but a response from the Alienware team really would be appreciated, I don’t think this time frame so far is acceptable!? Come on, this is a big company, with millions of Dollars to play with, a Dell engineer could reproduce what we have in minutes. I just don’t think this is good enough tbh. My system is under 3 months old, how do I go about returning it if it doesn’t work to spec? I look forward to a response.

policy = Alienware system return/refunds are only allowed inside the first 30 days from the Dell invoice date. DELL-Admin>

I would not blame the engineers as they are just doing their job. The problem seems to be the "bean counters at Dell" who are looking to maximize profit over everything else. IIRC, the chassis used in the R13/R14 is being used in another Dell desktop. They just slapped new plastic parts to make it look new.

They could have easily chosen a Corsair or Fractal Design Mesh maximum air flow mid tower case but the bean counters chose to go with the chassis used in the updated Aurora's. That's what the engineers were given the assignment to work with.

I have the I7 with a 3080TI in my R13.  I ran a very simple test:

Using HWMonitor to check the power/temp/mhz. 
For stressing just the cpu, I used CPU-Z (v1.98x64), 'Bench' tab, set the Threads=20 and pressed 'stress cpu' for version test v17.01.64. 

Started at all pcores=4689mhz / ecores=3890 / package 173watts @80degrees. 
At 90-120 seconds (was different each test) dropped and maintained pcores=4589mhz / ecores=3691mhz / package 160watts @ 77degrees.  

I next set the bench stress for 16 Threads, though the test cannot select which threads are being used.  This time the test remained steady at: pcores=4689 / ecores=3890 / package 160watts @ 80 degrees.

If I set the Threads=1, it is seems its grabbing a single pcore which gives me: pcore=4888mhz / package 46watts @ 45 degrees.  

Not a very scientific test as I am using basic tools.

Just ran Cinebench on my i7-12700kf.  Starts at pcores=4689mhz / ecores=3890mhz / package 228watts @ 93degrees. 

At 90-120 seconds (also different each test) first dropped to pcores=4389mhz / ecores=3491mhz / package 171watts @ 80degrees, another minute later the watts drops down to 160 with same core mhz with temps  @ 77degrees and remains this way until the test finished with a final score of 21,455pts.  

Single core test runs fine, it does not lock a particular core but the pcore=4888mhz using about 40 watts.

Got my 19-12900kf in my R13 to hit 5.27 Ghz but tends to crash after a couple of hours of gaming. I dont thermal throttle or power throttle since I swapped out the the 120mm CRYOTECH AIO that comes with the system at an extra cost to a Corsair 240mm aio with better thermal paste. But I still current/ Edp throttle. Can’t figure out how to keep it from doing so. Saw a video from “Gamers Nexus” that Alienware purposely current throttles the 19200kf to keep it from thermal throttling even tho I don’t reach the thermal limits to do so.  So no matter what I do to the settings in Xtu my R13 will current throttle since it’s programmed to do so from the engineers. I will never buy a Alienware product from here on. Will look for other prebuilt desktop manufacturers and will warn friends not to purchase from dell. If I do keep my R13 I will use it for parts like the GPU, Cpu, SSDmv.2, AIO, RAM and just purchase everything else to build my own rig. Lesson learned.

You can download Intel Extreme Tuning Utility and use the advance tuning to give yourself a negative offset to the core voltage.  Which AIO from corsair did you use?  Can you post any pics of the install?  Very interested.  What are your temps?  I get power throttled even when I'm in the mid 80's.

May 8th, 2022 13:00

This is exactly what I have done, via intel extreme n sent to dell. It proves what well have done.

Sorry but I still don't get why people who have paid $7000 AUD for a PC think an acceptable solution to this issue is to upgrade the unacceptable cooling solution at there own expense, or go dabbling for an solution in the voltage section of Intel's tuning utility.

The solution needs to come from Dell and nowhere else at there expense. There own specs state a 12900K or 12900KF will reach 5.20, it does not because Dell have deliberately throttled it because they knew the supplied cooling system and probably the 750W power supply were not enough.

You must be rich people to be offering a solution to a Dell created problem?

I don't think it says it will reach 5.20 Ghz. Not saying it is right, just thinking out loud.

May 9th, 2022 06:00

Well the time for waiting is over for me, my credit card provider is processing a chargeback to Dell, following the evidence I provided. I have offered to return my system for a refund to support.
