Precision 7530 & Precision 7730 owner's thread

Sorry, Was doing it with some background procesess before. It's around 3180-3200 stable but still it drops to 4.05-4.1Ghz. It's probably something wrong with XTU. Could it be that it shows 100% load but it isnt really that much?
Thanks for clarifying that Hwinfo isn't much of a reference. Didn't use it before and didn't work on mobile workstations before so some things are new to me.

 

Not all software push Cpu to use equal power consumption with 100% Cpu load and with same clock speed.

 

It is Furmark indeed. Sure, should have known that!
So in case of mobile hardware - is it always like that no matter what performance i get as a result I'll be always "producing" same amount of power in terms of wattage because both GPU and CPU are pwr capped?
If its the case, then 180W is more or less enough and until i change for example a graphics card for a more powerful one (theres only the case of modded BIOS but it shouldn't add that much power consumption as I initialy thought) the AC power supply shouldn't make a difference.
Should have told me all of that before, I would've come out less of an idiot.

edit:
I'll try and see why the power supplies do make a difference, maybe mine is broken.
Does charging the battery affect power output in any way? Then it might be it.

 

Charging the battery can consume, I dunno, something around 30W? It might make a difference if you are pushing everything else to the limit.

 

And if you're using ExpressCharge, it goes up to 75 W when the battery is nearly empty. However, I do believe that charging slows down when the notebook is under a computational load...

 

I'm actually using the AC optimized charging mode. If not Furmark then what is the best way to stress the GPU to the max? What are all of you using?

No battery drain whatsoever. Seems to me like stress test from XTU might be irrelevant as well. With it Furmark also doesn't throttle on any of the AC power supplies. I might have mixed something up as well since i use prime95 alternatively and its really late
Is there alternative for Furmark? Any program that can make 100% synthetic load? I think it still might be useful for testing stability.

heres https://www.3dmark.com/3dm/34851298? firestrike, had only time for one run, its 4am here.

 

Using Firestrike in a loop on just one test will push the GPU to 97-99% utilization; I use that to check temperatures sometimes. (The loading screen is skipped if it can loop on a single test.) I think that you have to pay for 3DMark to get the option for this, though...

 

3DMark Fire Strike, Time Spy. Any recent AAA video game at 4K resolution (you'll need an external monitor for this), like AC Odyssey, Kingdom Come: Deliverance, Shadow of the Tomb Raider, Battlefield 1, Battlefield 5. If the Halo MCC comes out soon, that might be a good benchmark, too.

 

Ok, this is weird because when I put Unigine Heaven together with Cinebench on smaller PSU, I can actually see "Connected, discharging" under windows battery tray icon.
In about 10-15 minutes it went from 100% charge to 96%. Might have as well been happening yesterday I just didn't see it plus I was really confused by all the figures, but the fact is that with bigger adapter I suddenly had higher scores in 3dmark and also no power drops under 100% load.
Before you ask: Yes, Power Adapter is connected correctly, when I turn off even one of the programs; it starts charging.

I actualy did bought a kill-a-watt because now I am really curious what's happening. I've read a review today of 7530 just like mine (but with 4K instead of FHD screen), when they measured power consumption under 100% load it was drawing a 174W (with a standard GPU BIOS).

Probably tommorow I'll have my own 330W power supply, a Kill-a-watt and plenty if time to see what's really happening. A few pages ago i saw someone wondering about the same thing so I hope I'm not the only one still interested in this...

 

Hi, thanks for reply and sorry for late answer.

Did you check on your 7530 right ?

Because on all these reviews:

https://www.laptopmag.com/reviews/laptops/dell-precision-7730
https://www.productsrace.com/reviews/dell-precision-7730-hands-on-review/
https://laptopmedia.com/laptop-specs/dell-precision-17-7730/

is reported 720p. (on other sites i've found further info like 0.92 MP 720p@30fps).

Hi, thanks for reply and sorry for late answer.

If you can do it, you would be very helpful.

About throttlestop, could you post a screenshot like this (FIVR):
http://forum.notebookreview.com/goto/post?id=10882738#post-10882738

and this (Power limits)
http://forum.notebookreview.com/thr...0-owners-thread.820539/page-202#post-10883267

Are you able to set multipliers like this ?:

1 Core Active---->47
2 Cores Active--->46
3 Cores Active--->46
4 Cores Active--->45
5 Cores Active--->45
6 Cores Active--->44

If so try to apply -140mV undervolt to both cpu core and cpu cache and then run for example Aida64 system stability test (Stress CPU only) for 10 minutes max and using "CPUID HWMonitor" check these ?:

1- Cores Frequencies
2- Cores Temperatures
3- Cpu Package Power Consumption
4- Cpu Tdp

Don't forget to post screenshots of every step, it would be very helpful for anybody (not always me).

To @tom7730 and @DreamThtr :

Hi!

I've seen you both have 7730 and i'm currently leaning towards this model too.
So far are you satisfied with your purchase ? I mean do you feel 7730 is worth the price dell is asking considering what other workstations are on the market ?
Mind if you share your thoughts about your units ?
Especially build quality, fan noise under light and heavy load, keyboard, trackpad and trackpoint (if you use it).
Palm rest area is a fingerprint magnet ?
What panel do you have ? If it's fhd, what model is it ? (you can use hwinfo to check it).

Could you also tell me the thickness of the laptop with both the lid closed and open ?

Hope in your answers !
