Precision 7560 & 7760 Owners' Thread

Always like it when I ask a question that I think everyone else knows the answer to, then it turns out I'm not the only one who doesn't know!

 

In case it's useful for anyone, my 7560 arrived yesterday with its 64GB of quick RAM (I know, I know, but the RAM is always more tweaky than the SSDs and I didn't want to have any issues with it). While replacing the SSDs with alternative ones I noted the info from one of the sticks of RAM:

ADATA
AO1E34RCSV1-DB7S
16GB 1Rx8 PC4-3466AF-SA2-11
10411151 1.35V DC:2115

Cheers, Dave

 

Now that my 7760 shipped, I was able to look up the system original config. Looks like the 2TB SSD it shipped with is a Samsung PM9A1. I will confirm after I get the system.

 

General question about GPUs.... I'm finding that software I used on my 7740 that made full use of the RTX 4000 is now, on my 7760, not making much use of the RTX A5000.

For example, the photogrammetry software I use has the RTX 4000 running at 98-100% utilisation. Running the same model on my 7760, the RTX A5000 is only at about 8% utilisation (yet is still building the model much faster than the 7740).

The same model with the same settings in Solidworks Visualize 2020 renders MUCH slower on my 7760 than it does on my 7740.
(EDIT - I've seen a post on reddit talking about Visualise 2020 not being able to use the Ampere GPUs, so are restricted to CPU rendering)

Is it something to do with drivers taking a while to support certain applications when a new GPU is first released?

Thanks

 

Pretty sure it's quite bottlenecked by RAM. At least for Meshroom, the GPU is only utilized in specific parts of the process.
I don't know what's going on with Solidworks Visualize considering that Ampere GPU's are nothing new (maybe mobile "quadros" aren't supported yet since they are newer?)

 

Hhhmm... Both PCs have 128GB RAM and were only using 40-50GB for this project...

According to what I've read (which was from 6 months ago) Visualize 2021 supports Ampere, but 2020 doesn't... Makes sense if they want you to keep upgrading SW I guess....

 

For Meshroom, in some stages, the CPU is limited by RAM speed (I think), not capacity. However, in some parts, there isn't a RAM bottleneck. Pretty sure that the texturing and mapping stage is the stage that takes up an absurd amount of RAM, and the rest don't take up as much. Keep in mind that Meshroom isn't that optimized, which might explain it's inefficient use of resources. I have minimal knowledge about photogrammetry software, but if it does the job noticeably faster, it's utilizing the new system and I wouldn't worry about a lack of usage.
Also what software do you use to monitor GPU usage? Different software reports different "utilization/load" values since they calculate it differently.

 

My 7760 just arrived a few minutes ago, and I had my 7740 here with me as I took it out. Upon taking it out of the box, I never noticed how much narrower it is than the 7740, and thought for a moment that I mistakenly got a 7560. I actually liked the 7740 bezel thickness because it was the perfect width to comfortably grip it with my thumb without touching the screen when closing the computer, but oh well, at least it still has a bezel.
I got:
i9 11950H
RTX A4000
120Hz UHD non WWAN
8GB RAM (will just move the RAM that's on my 7740, this 8GB stick was single-channel.....)
256GB SSD (ditto as with the memory sticks)

for slightly under 3,000USD with taxes.

Oh and for anyone that's still awaiting their precision, here are the dates for my updates:

12 July, order placed and confirmed
15 July, order in production
21 July, order shipped
23 July, order delivered.

 

Also, I bought the long-life battery because I didn't know about what was mentioned here earlier, regarding Dell not allowing the long-life battery have a custom max charge/min charge in the BIOS, however I can confirm that at least when I checked just now, I did indeed have that option available, and was able to set my max charge.

Edit: Nope nevermind, for some reason after accessing BIOS a second time, that portion of the battery options is indeed greyed out.

 

I also didn't realise how much smaller the 7760 is than the 7740 until I put it in the same neoprene sleeve I used for the 7740. It was really tight on the 7740, but it's noticeably too big for the 7760.

Another thing I noticed is how much better the cooling system seems to be on the 7760. It seems to run much cooler than the 7740 and blasts hot air out of the vents like a fan heater. The airflow from the 7740 never felt like that and it used to occasionally shut down due to a "critical thermal event", even after Dell installed a replacement cooling system.

Very happy with it so far.
