Precision 7530 & Precision 7730 owner's thread

Sure! Still interesting for me to compare to get a better idea of the performance of the Dell i9 vs my desktop.

 

If you want to see unthrottled 8950HK performance that matches your stock 8700K, take a look at the MSI GT75.

 

I agree. In fact, the i9 was a last minute decision during configuration because frankly, me hesitating about the CPU was more expensive than the upgrade

For my profession, It should ideally maintain a 100% CPU load for ~30 minutes. Now, even if it throttles it's still a massive improvement over my previous laptop. I'm probably going to do some stress testing and tune the voltages / power limits / max frequencies until I can get it to last 30 minutes without throttle.

I'm contemplating whether I should try a repaste or not.

 

Hi! I am considering of getting a 7730 for deep learning and data science.

I would like to find out the heat generated from Dell 7730 vs a typical gaming 17"laptop such as R5 alienware.

Does E2186 processor and Nvidia Quadro vs i7-8750H or i7-8850H and 1060 or 1070 lead to more or less heat?

Appreciate the advice.

 

If there are heat issues, is it necessary to get a notebook cooler? Any recommendations?

 

Precision 7730. I9cpu with p5200. .G.skill 3200mhz ram , 64gb, causing stability issues. For the most of time the system won't boot up, or freeze after a couple of mins. Generate a lot of heat . I turned off the Intel graphics yif that matters

 

Nice machine. Thanks for the updates.
Like i said, actually the normal ordinary ram will be just fine. Forget about ripjaws, hyperx or vengeance, they can cause issues(usually they might require more current than ordinary ones), especially for precision series.
Perhaps you need to wait for dell to release new bios to support them, that usually might take quite a long time, i mean at least several months. But again there is no guarantee that your gskill then will work as stable as ordinary rams.

 

The first thing I would try is put in the original RAM and see if that helps with the stability.

 

Quadro and Xenon GPUs and CPUs produce relatively the same amount of heat as their GTX and Core i series counterparts. They use the same architecture and have the same TDP.

Ultimately those with higher clocks and unlocked firmware will produce more heat, and have more performance, but will throttle sooner if thermal design capacity is surpassed.

For your application, I would not get a Dell or or any other brand workstation grade laptop at all. You should be looking at a Clevo with Desktop CPU and firmware unlocked GTX 1080 at full 180W (for far less expense than P5200 which is no better at deep learning). So far all these workstations P5200s have been firmware locked to under-perform. Also you can get GTX 1080 laptop even cheaper than a P4200 laptop.

Quadro GPUs aren't for scientific computation, (Tesla GPUs are). Quadro cards are designed for accelerating CAD and Modelling, so they won't help you to train neural nets. They can probably be used for that purpose just fine, but it's a waste of money.

 

BIOS 1.2.5 is posted.

- TPM configuration is fixed to address TPM startup error when resuming from sleep.
- Cannot display Dell logo on external monitor in cold boot or warm boot with "Do nothing" lid closed.

Enhancements:
- Improved Embedded Controller Engine Firmware.
- Improved Intel Video BIOS.
- Improved Power Delivery Firmware.
- Improved BIOS recovery process.


I've been having issues with the system not drawing power from the Thunderbolt dock when it is plugged in. (All of the stuff connected to the dock works, but the system is running on battery power.) I have to un-plug and re-plug the dock, sometimes a few times, before it will start drawing power from the dock. I wonder if the "power delivery firmware" change will fix that...

[Edit]
Nope, it's even worse now... Immediately after the firmware update finished and the system rebooted, before Windows even started, it complained about an undersized 130W power adapter being connected. (I had the TB18DC dock connected.) I shut the system down and unplugged/replugged the Thunderbolt connector and the power supply going to the Thunderbolt dock. Now, it won't draw power from the dock at all. I'm forced to run with a separate AC adapter connected.

[Edit 2]
I noticed that the posted changelog text file has more information, including information from internal/unreleased versions. For example:
> 1. C1822-N202: BITS374138: Updated thermal table to fix the higher fan noise.

[Edit 3]
Took laptop to a meeting and now that I'm back, the TB18DC is providing power again. Guess I didn't try unplugging/replugging enough times. Still, clearly there's an issue there.
