Precision 7550 & 7750 Owners' Thread

Ethereum in that screenshot yes, and I've seen "board power draw" hit the neighborhood of 110W, as would be spec'd from NVIDIA themselves, which is just weird.

At the same time, it looks a lot like my RTX 3000 did in terms of overall GPU-Z sensors but it didn't drop mining performance like this... at least not consistently.

 

Yeah, I am wondering if the 90W limit is supposed be for the "GPU chip"? Under normal (3D) workloads it would be dominating the power use a lot more.
...The best theory that I can come up with is, since so much of the work is happening "off the core" (as evidenced by its comparatively lower power use compared to the whole card), upgrading to a larger core might actually be detrimental in this workload as it will use more power at the same clock speed, drawing away from the limited total power resource.

 

Mining was only a secondary goal. The 3000 was slower than the GTX 1080 in my old Devil's Canyon gaming computer that I wanted to retire, so I just up and grabbed this thing and now I can fully retire that thing... I was just hoping there was a way to somehow stabilize the mining performance.

Also. Page 69. Nice.

(sorry. I had to)

 

More thoughts: normally I have it tied to a WD19DC to power three monitors and a host of other ****. I'm at work now, where it's dockless because my TB16 just stopped for some reason. It's now mining stable at 27.xxMH/s...

Is it possible the dock is angering the rest of the kit? Or maybe with a 110W TDP, maybe the machine won't throttle up until it's got a 240W power supply instead of the 180W it comes with or that the dock can supply?

 

Interesting ...
So if I am understanding you, it mines stable with an AC adapter connected (180W?) but performance is throttled when you are connected to a WD19DC dock (...which is "supposed" to be able to kick out 210W)?
Not sure why that is, but I've had flaky behavior from both the TB18DC and WD19DC dock on my Precision 7530. Since the lockdown last year, I've been dockless and happier that way. But even with the dock setup, maybe you could just try connecting an AC adapter directly to the system in addition to the dock cable and see if that helps out.

 

I'm trying a few variations and the speediest is undocked with a 240W and the Intel GPU disabled completely. Next in line is docked to my -16 which requires the 180W+ adapter hooked to the computer; Intel irrelevant. Then there's the chaos with my WD19DC. Three 1440p/72Hz displays (and yes they work that way most of the time), among other USB devices and whatnot. My 7530 hated docks, the 7550 is flawless with 'em. I think there was a general problem with the '30s and docks, but that's a whole 'nother story. Either way, I can't really go dockless at my main station cuz that would just defeat the whole purpose here. lol

Will the -19, or the -16 for that matter, work with a 180W supply or does it *NEED* a 240W? I can cuff the 240W from work to confirm some things.

 

Okay. I have it home, and with the WD19DC dock and an ADDITIONAL 240W PSU plugged into the back, there's no discernible difference. Time Spy score is up with the new card though, by almost a thousand, so there's definitely improvement in other areas, this just just WEIRD.

 

TB16 can't deliver more than 130W to the system so it should be fine with a 180W PSU. You'll have to have a separate adapter connected directly to the system.

A "dual-connect" dock should have a higher than 180W PSU connected. (They ship them with 240W PSU included.) There is some overhead from running the dock itself so if you have a 180W PSU connected to the dock, it won't be able to deliver a full 180W to the system.

 

Yeah they both have 240's on 'em, but I was asking since I only have two 240W adapters, one at home for the -19 and one at work for the -16. Was thinking of switching the 180 and 240 around to keep one plugged into the computer, but I'm not seeing much difference on the -19 whether it's a 240 or 180 in the back of the machine... Actually sometimes it flat out rejects the other power supply and the dock stops functioning, so it has to be exclusively the -19 when it's hooked up to that.

I guess I'm still just confused on the apparent lack of pattern when it comes to mining performance, since every other load I've put on it is stable and fast.

 

Hi,

I’m thinking of buying refurbished 7550 directly from Dell Outlet. There are a few options available with different CPUs.

I want to use it for anything you would consider general use + coding/virtual machines and maybe photo/video editing from time to time. Technically, I could do those on laptops less powerful than precision line, however I like having a powerful one just in case.

Does anyone have experience with i7-10850H (6 cores), i7-10875H (8 cores) and i9-10885H in terms of performance/temps/fan noise?

Would it be better going for 6 cores instead of 8 cores since I assume it’s going to be easier to keep that cooler?

Also, does anyone have experience with installing dGPU on their own? How much of a pain is it to do that for someone who has experience building regular ATX size systems?

Thanks in advance for any input on that.
