W00T 330w brick works!
saw 288w being pulled out the wall during AIDA64 full stress test,

What was the max you saw from the 240W?

(288W is likely around 235W going to the system after AC/DC conversion loss.)

235w was the max i saw with the 240 brick before (with the same power meter),

just run AIDA64 complete stress test,
during the test the unit pulled constantly thorough the whole 10min test 275w,
and was not thermal throttling for some reason (need to investigate further),

 

 

 

the 330w brick is big thick and heavy,
not something id ever want to travel with,

 

[MyPC8MyBrain]

im baffled, no thermal throttling despite the high wattage pumped through, i thought it was some mistake the first time i noticed it, i guess i wasn't imagining things after all, with the 240w brick thermal throttling is almost instant (below vid is with ultimate power plan in windows and Ultra Performance in bios on),

 

[MyPC8MyBrain]

despite the 330w brick and obvious extra power being pumped through,
3080Ti remains stuck on 120w max usage, i raised another ticket with dell pro support for this,
lets hope its a simple configuration error carried over from the 7670,

 

if they fix this issue my next issue will be finding a solution to running fans at full blast manually,
the 20 year old logic still embedded in both windows and Dell's old bios power plans is just too anemic for these powerful cpu's, we need to be able to use fans on demand,
especially for buffering heavy work loads in advance,

7770 stripped down P.1

7770 stripped down P.2

  

 

the replacement unit that arrived came with Delta fans with denser fin formation
(i think that's the part @Aaron44126 replaced), on the left is the first unit with Sun On fans,
the one on the right is the newer replacement with Delta fans,

Thanks for testing that. I have been a proponent for a two brick solutions for these laptops for some time now.

Use a really big one in the place where it is used most intensely and a lighter one for traveling and at least it will not be power limited any more.

 

Would be interesting to see if running a TimeSpy test you see any differences in power consumption and score. With current gen MSI units I have seen short peaks of up to 350 and a sustained draw of well beyond 235W.

I think i cant see the tree, in front of me, in a forest...

Why all of TB ports are sooo slow in file copy? 8-10Mb/s is the max what i can see.

I try out the ADATA SE800 1TB drive, and slower copying to nvme, than my old Lenovo G560 in usb 2.0

What i miss? need some more drivers or apps?

thx.

[pintie]

mine work with 40Gbit/s (ORICO M2V02 case with samsung 980 pro) absolut perfectly.

 

i'm using the Dell Tool to keep the drivers up to date.

decided to re-paste again with LM this time on both gpu and cpu, and so I did,

Hi, can you provide some tips when applying Liquid Metal on 7770? Did you use electric tape to prevent leakage? I wanna try it but I have never done repaste before. Thanks! 

[MyPC8MyBrain]

@Jack
YouTube is your friend,
spend some time watching few videos on how it is done you should grasp the process pretty easy, 
if you scroll back you will find handful of repaste tips and pics i posted throughout this thread,

good luck,

 

[Aaron44126]

Normally using Ethernet.  Ran on Wi-Fi overnight and woke up to find my system had crashed from a BSOD (Netwtw10.sys ... Wi-Fi driver).  I have the current Wi-Fi driver installed, 22.170.2.1.  Great...?  This system has been normally quite solid for me, stability-wise.  (I'll just go run an Ethernet cable to where I was sitting yesterday and do a more in-depth stability test after another Intel Wi-Fi driver is posted...)

 

Also, I inspected the fans after about four months of use.  Very dirty.  Regular cleaning required.

 

[MyPC8MyBrain]

wow how are these fans moving any air for the system being this clogged after 4 months,
 

interesting, there's another SunOn fan model,
you seem to have a model with dense fin formation like the Delta in one of the systems i received,
the Sunon in my current system has a less dense formation then yours (i noticed it immediately when i saw it),

be very carful when removing the cover, the cpu and gpu are not very secure or supported in there, any movement could cause paste movement and loss of performance, i noticed over 10c increase from adding m.2 drives in and out, at first i thought it was the m.2 drives adding overhead to the cpu raising its temps by 10c,

Have you paid attention to the max fan RPM speed that you have observed?  (Dell Fan Management can report the fan speed.)  Mine seems to top out at around 3500 RPM, whereas in older Precision systems I have regularly observed mid/upper 4000's.  I'm wondering if the other fan models are different.

i have used your Dell Fan Management tool, i observed well above 3600 rpm, i think it goes above 4000 rpm,
but i never stress tested with the tool monitoring during stress test just when it switches to cool power plan there's a ramp up window during that i observed, i can run a quick test to see what we have here,

[MyPC8MyBrain]

i was wrong (must have mixed it with older 7670),

this one goes up to 3600 rpm,

 

[Aaron44126]

About the same as mine then.  I wonder why the fan speed is so restricted...  (I guess they are a bit larger than the older fans.)

Mais ou menos o mesmo que o meu, então. Eu me pergunto por que a velocidade do ventilador é tão restrita ... (Eu acho que eles são um pouco maiores do que os fãs mais velhos.)

7540 fans go up to 5100+ rpm at high load.

[MyPC8MyBrain]

my best 7770 3DMARK Time Spy score so far 12145, allot of tinkering to find the right undervolt balance,
what's interesting is with the right undervolt settings i am finally able to maintain 4,423 MHz average clock frequency throughout the test (with all my previous attempts i got good scores but cpu always ramped down to 2000Mhz), still getting slight thermal throttling but not enough to ramp the whole system down,
25.5k scores in CB23 are a regular occurrences now, trying to hit that illusive 26k CB23 score,

I'm just about to purchase a 7770 at work for a new job I've got as a 3d artist

Am very worried about the performance of the laptop as the software I use (cinema4d+octane render) requires pushing the GPU at 100% for hours for renders (will be purchasing 3080ti or a5550 model)

Can someone with one of those GPUs please run an octane benchmark and let me know the score?

 https://render.otoy.com/octanebench/

My personal msi laptop with a 3070 gets a score of 376 (and is pretty slow to render) so really hope the 7770 will still be able to beat that even with the thermal/power issues

With 3080Ti, I got 399.  I think the GPU power limit is going to be the main limiting factor in a test like this, if you're just comparing various Ampere GPUs...  You'd definitely want a 17" system for best performance, but if you want to push the GPU power limit any higher than what you get in the 7770, you'd basically need a gaming-focused laptop 😕.

same here,

 

if you get the 7770 without dgpu, connected to external enclosure via thunderbolt with 4090 gpu you should have a chunk of change left with twice the performance if you went the 3080Ti or the A5500 route in the 7770, the 3080Ti and the A5500 are both priced over $2200 option for the 7X70 line,

For performance, I guess the best you can get at the moment (at least without any tweaking) is still an MSI. CreatorPro X17.

By chance does anyone happen to know the sustained TDP for the 7670 A4500 GPU? From Notebookcheck's review I can see the 7670 A5500 is about 102W but wondering if the A4500 is the same.
