Precision 7550 & 7750 Owners' Thread

In addition, if you can wait until the 7560 is released, or at least announced, there may be bigger discounts on the 7550 to help move out excess inventory.

I have a Dell 7750 and the touchpad seems to freeze. For example, if you move the mouse from the right side of the screen to the left, it'll momentarily freeze. You can keep moving your finger on the trackpad back and forth and the mouse curses will sit there on the screen. Then after maybe five seconds, it'll start responding again.

I booted into the BIOS and it does the same thing in BIOS. I have the latest BIOS and firmware installed on the PC. I'm wondering if there is anything else I might be missing.

 

So I've got basically a maxed out 7550 (ignore my sig if that disagrees because I haven't updated that yet), except for it having the RTX 3000. Bought a 5000 on eBay and it works, but I think it might have a weirdly modified or non-Dell vBIOS in it, as I've seen it drawing 110W under load, and it also misbehaves at times when I'm mining. Yes, I mine on it when it's idle, bite me lol.

Anyway, I tried flashing it with the firmware updates available from Dell but I don't think those took. Does anyone have a clean vBIOS from Dell that is flashable to this somehow?

 

Download and run this exe from Dell itself.

Note that your power limit will go DOWN as a result of this.

 

Tried that, had zero effect.

 

Did it flash at all, or did it throw an error or something? If it's the latter, you can extract the actual flasher binary from the EXE and run it directly.

 

It appears like it would have flashed. No errors. Blank screen and hardware add/remove Windows alert sounds... but no change in power limits or behavior.

To specify "misbehaving" in mining (I have not done analysis on 3D performance aside from ONE Time Spy run after I got the card installed yesterday): When the miner is initialized, I'll see 35-38MH/s, but it will progressively drop to about 15MH/s over the course of 15-30 seconds. I can boost it up to 24MH/s by watching Twitch or YouTube but only if it's actively on-screen. My old 3000 did 24MH/s multitasking and 28MH/s left alone, for the most part. Would sometimes drop to the teens if it got too warm.

 

Wondering is setting the power management mode to "prefer maximum performance" in the NVIDIA control panel would impact this at all? It might be throttling down just because the system thinks that it is idle (...since you're not doing anything on the display).
Does GPU-Z show anything under "perfcap reason" on the sensors tab?

 

Tried that with the NVIDIA Control Panel and that Inspector program. No change. You can see the drop in GPU clock and related drop in mining speed after simply closing the video I had open, but it always reports power as the perfcap.

 

Kind of surprised looking at that GPU-Z screenshot, if the GPU is really drawing around ≈100W while running at such a low clock speed, that just seems really surprising. Of course, if it really is drawing that much power, "power" is the appropriate perfcap because it's only "supposed" to be drawing 90W.

Granted, this isn't a workload that I'm really familiar with.
