Precision 7530 & Precision 7730 owner's thread

It means the Nvidia GPU is now driving all of your displays.

You might have to play with the nvidia drivers in Linux.

 

Try with switchable graphics enabled, but the "Direct discrete graphics output mode" checkbox next to it disabled?

 

I am finding that that the power cable connection to the 7730 is looser than in the 7710 and earlier models - the silver portion of the cable doesn't fully go into the laptop.
Anyone else have this issue?

 

That's probably because of the slightly angled back—if you take a look at the DP, HDMI and Ethernet connectors, they're all also a little askew.

 

So, I repasted my notebook today, and took photos of the bare Quadro P3200 DGFF, if anyone is interested:

 

A few notes; it looks like the card has 4 VRMs for the GPU, and one for the VRAM. Might get away with flashing a fairly high-powered VBIOS, and the WinBond chip is right there, too. Pity the heatsink has to be removed.

 

Here is the datasheet for the MOSFETs on the front side Vcore VRM: https://www.onsemi.com/pub/Collateral/NCP302045-D.PDF

Looking at the efficiency curve at 12V Vin, 1V Vout, at 500kHz Fsw, looks like it's 90% efficient at about 25A Iout, so I probably wouldn't push it much over 100W unless you have good active cooling for those FETs.

 

I used the precision 7730 for a month and had several issues as mentioned previously. A good laptop depending on what you are doing. For music it isn't well suited. I now have a Macbook pro 15, Vega 20, 4tb SSD, i9, 32gb ram and honestly couldn't be happier. The operating system is nearly flawless and I am able to use 32 sample buffer with a number of VSTs running and no dropouts. Performance is steady and no thermal throttling. Video editing with Final Cut is great because it's optimised for the hardware. A 4k clip that takes 50 mins to stabilise in Premier Pro takes about 3 minutes in Final Cut and I also haven't had a single crash. I am very impressed with the Mac but do believe it's overpriced (around $10k), all the dongles you have to carry around is annoying and adds reliability issues, lastly, the body is too thin to really take advantage of the CPU and GPU. The Precision ran at a steady 4.2 Mhz whereas the Mac (same processor) runs at around 3.1 Mhz. The Mac is much more stable with temperature and clock speed though. The Mac outperforms the Precision in most situations because the OS is optimised for the hardware I think. Overall, I'm very impressed with the OS and will not go back to Windows anytime soon. Just wish Apple would release a 16 in workstation with proper ports and adequate cooling.

 

Software-hardware optimisation can only go so far, and Macs are x86_84 computers, anyway. This gigantic discrepancy must be explained by something else other than merely 'OS X has better hardware optimisation'; I am inclined to believe that there might've been

That is outrageous for a computer; with that much, if you were doing hardcore rendering and video processing, a desktop workstation would give you both greater value for money, and greater performance.

However, it is great that you have found a machine suitable for your needs. I hope all goes well!

 

$10k in US dollars?!
