What I said about blocking the PL1 at 45/55W has nothing to do with lowering MHz. This is to leave room for Dynamic Boost to increase GPU power, increasing the graphics score. You probably need to also limit the PL2 as your liquid metal system must try to maintain 157W during the entire PL2 actuation period and this will not allow the dynamic Boost to kick in Obviously you will have a loss in cpu score but a gain in graphics score. Not simultaneously! Only in the cpu test the 157W must be reached because in this test the load on the cpu is high and on the GPU it is lower. According to your video, during cpu test the consumption of the whole system is ~225W. In the graphics tests this consumption is around 190W. Edited: checking the total system power consumption on your video during graphics tests it is likely that there is some limitation imposed on CPU + GPU power limit at high simultaneous loads. This limit is probably ~170W. If this is correct then for Dynamic Boost to kick in the CPU power cap should be ~30W.

But that's exactly what I'm saying. Clock is fixed at the maximum during graphics tests 1 and 2 because the load on the cpu is low.

Exactly, it's at 4.7GHz due to the high-performance power plan, but it's only holding that plateau because the load during the graphics tests is low. In the CPU test the load on the processor is much higher. Check, run Time Spy on one screen and leave HWiNFO open on another. Or do you believe that this Precision (even with liquid metal) can simultaneously maintain 157W from the CPU plus 120W from the GPU?

The processor clock is fixed at 4.7GHz during graphics tests 1 and 2 where CPU load is low. In the processor test there is a slight drop in the clock rate. GPU clock is dropping considerably in graphics test 2. My hypothesis: You've set the PL1 to 85W and checked the MMIO box blocking dynamic power cap adjustments and this makes the processor power work at a very high cap during TimeSpy. This means that Dynamic Boost has no "room" to kick in and the GPU is limited to base TGP (maybe 125W???). If you limit the CPU power during the benchmark to somewhere between 45 and 55W, you will likely see an increase in the 3080Ti's power consumption, increasing its clock rate. With this your global score will increase, as timespy gives much more weight to the graphic score.

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

Huge increase over the last best score! What settings changes did you make?

To verify and understand the behavior of how the system allocates power between CPU and GPU, run AIDA64 CPU stress test and Heaven or even Prime95 and Furmark simultaneously. After a period the system should stabilize maintaining fixed values of power for both, or, as dell likes it, the power can vary, increasing and decreasing in cycles.

nope, it didn't reach 100c during the 30min run, one core reached 91c at max peak, Can you change the PL1 for the CPU to stay above 70/80W? If maintaining 157W for some time with the maximum of 91°C it would probably end the 30 minutes sustaining 110W (or more)... At 86°C there is already thermal throttling. The temperature limit for using these GPUs is 87°C and at 86°C the clock drops. I believe this GPU should stay around 130W. If it kept the 150W the rating would be higher...

Your CPU results are fantastic. What's the sustained power during the 30 minute test? I imagine the temperature stays at 100°C in this longer test, right? As for the GPU, how many Watts does the 3080Ti consume, average and peak, during a graphics benchmark? Anyway, I believe 11500 on Time Spy is a fair score for this GPU with ~130W... If you limit the CPU you can still increase the graphics score and consequently increase the overall score.

I prefer to wait another generation, hoping for a more mature and better resolved project. My disappointment is not only with the undersized cooling system, I also didn't like having to choose CAMM memory to get more than 64gb... I believe that the next generation will reuse the current design, but with necessary refinements, in addition to the gains with Raptor Lake and RTX 4000... I love the 7540, it has served me very well for the last 3 years, but I made a mistake in choosing the configuration. I opted for i7-9750H to reduce costs and only 6 cores are weighing on my activities. If I had opted for i9-9880H I believe I could have kept it for another 2 or 3 years...

I planned to buy a 7670 to replace my Precision 7540 this holiday season. I gave up.... So I researched about P16 and Fury 16 G9... I'll wait another year!

Parece que o TGP no Fury 16 G9 permanecerá muito limitado como nas gerações anteriores. Além disso, a potência a longo prazo é baixa para aproveitar o potencial dos processadores HX. Cinebench R23 = 18680: laptopmedia.com/processor/intel-core-i7-12800hx/ https://laptopmedia.com/review/hp-zbook-fury-16-g9/#gpu-options

I tested the 7540 connected via Thunderbolt port to the dell P2723QE monitor with PD of 90W and it works! I believe Dell has blocked the PD of the 7540's USB-C ports for use with 3rd party chargers...

I repasted with NT-H2 and my Precision 7540 had fantastic thermal gains....for about 3 weeks. NT-H2 is not very viscous and with constant use at high performance has a tendency to drain into laptops. The heatsink pressure is much lower than on desktops and the probability of the pump-out effect occurring is very high. Originally, without undervolt, in multicore CBR23 the i7-9750H hit 100°C at 90W with 3.6/3.7GHz on all cores. With Noctua it dropped to ~94°C at 90W with 3.8/3.9GHz, without thermal throttling. After 15/20 days the performance degraded at 75W at ~94°C. I currently use Thermalright TFX and the performance remains the same after 2 months, almost equal to noctua for the first few days. This is CPU related. For GPU Noctua works very well due to lower temperatures. No flow occurred and performance didn't degrade.

This is exactly what is to be expected for the Precision 7770. 157W starting and 85W sustained. I intend to change my Precision by the end of this year and I liked the P16. My preference would be for the 7670, but this CAMM module and in the future only 2 SODIMM modules, will probably make me go to the competition.

Very good! For this score the P16 must have ~110W sustained on the CBR23? What is the TGP of the A4500? 115+15W? Are the temps good?

where is the information from?

How many Watts sustained in factory default? My 7540 sustains up to 90W with Thermalright TFX (undervolt off) at ~93°C and ambient at ~21°C. New and with original thermal paste it was 75W at the same temperatures... Aaron's unit certainly has a problem. His Cinebench score is lower than a Precision 3571 with (6+8)c/20t.

It is not expected to reach the performance of X17, GE67/77, etc...these are gaming machines focused on high performance. This 7770 is expected to deliver consistent good performance, a more reliable machine. Precision has always prized stability, reliability with good performance. I'm convinced that Aaron's unit has a problem because at multicore full load his CPU can't even reach the value of PL1. The expected would be to reach something between 115 and 157W (PL2) - depending on the cooling capacity - for a few seconds before throttling and staying at 85W (PL1) with a temperature below 100°C.

Aaron44126, the multicore full load performance has already shown, it would be interesting to check the maximum capacity of the system when CPU and GPU are demanded to the maximum. If possible I suggest following Jarrod and simultaneously running cpu stress test on Aida64 and Heaven. Check temps/clocks/power of both. Thanks!

I saw this review...but I don't even consider the possibility of the gpu being limited to 55W when in full load simultaneously with the CPU. It's certainly a bug to be fixed with an update. His at least has a sustained power of 85W with the i9 in multicore full load. Impossible for dell to have done all this internal update to get these results. I have a Precision 7540 and I get 75W sustained on the CPU (i7-9750H) and 60W on the GPU (T2000) running Prime95 and Furmark simultaneously.

It's not a matter of squeezing the most out of the hardware, looking for every point in benchmarks, but the performance of your 7770 in both CPU and GPU is below acceptable. If this is the standard the new 7770 represents a downgrade in cooling capacity compared to the 7740/7750/7760. On the CBR23 the score, sustained power and temperatures are horrible. A performance level close to that achieved by the GT77 was never expected, but an acceptable performance for this precision would be able to maintain the 85W of the PL1 without thermal throttling reaching 17500-18000 on the CBR23. On Time Spy its CPU score is super low, at the level of an average i7-11800H. The 3080Ti is also low, with a maximum TGP of 150W its score should be ~12000. My guess is your unit has a problem with either misapplying thermal paste or poor contact heatsink... Otherwise, why a high-end i9 HX + high end dGPU if the system can't extract minimally decent performance for the hardware?

I contacted support and they don't know if it's a lock done on purpose by Dell, if it's a problem or something else. They simply claim that Dell cannot guarantee the performance of third-party products. Luckily I have a P2723QE monitor with USB-C Hub with 90W Power Delivery. I'm on a business trip and as soon as I get back to the office I'm going to test it on a fully Dell system. At most I have faulty Tunderbolt ports and I will get a 7670 in return... Thank you very much for your attention Aaron44126!

Hey guys, I bought a 100W USB-C GaN charger with the intention of using it in my Precision 7540 when I'm out of the office, obviously for lighter tasks...I've tried everything and I can't charge the laptop through the Thunderbolt ports. Windows informs that the system is not being charged and in another message it informs that a charger of at least 90W is necessary for this to work. Well, I've already tested this GaN on two Inspirons and it worked perfectly delivering all the machines' performance. Are the Precision 7540's Thunderbolt ports limited for charging via third-party chargers? I have a problem? I often use both USB-C ports with flash drives, external hard drives, smartphones, etc... Sorry for my english, it's not my native language.
