Dell Precision M4800 - Can GPU be upgraded?

only 1 pci express lane is not good is it?
most my graphics card in the past either used 16x or sometimes when i did sli i would have 8x and 8x for the 2 dgpu's
yea i think i might try and get the m2200.
do i mod the nfo file like i did for the m2000m?

will the m6800 motherboard fit inside the m4800 case?

 

You will have to mod the INF for the M2200.
There is no way that a M6800 motherboard will fit in the M4800 case.

 

Expresscard (on everything before Skylake) uses a x1 2.0 lane, which is 5Gbps or around 4Gbps after overhead is calculated. It is connected to the PCH along with all of the MPCIE slots, ethernet, and a couple of other devices (card reader maybe?). They all share a x4 2.0 uplink (20Gbps) to the main CPU (called DMI). The main x16 3.0 lanes off the CPU go to the MXM slot in this machine. I'm unsure whether having SATA devices active puts pressure on that DMI link, but it shouldnt be nearly anything and whether theyre in a RAID matters not.

I'd personally go for the expresscard route (EXP GDC for ~$50 or so, $15 PSU, then a $100 RXD 580). It will perform much better than the M2200 even at x1 2.0 link speed.

 

i seen a map of how the pci express was layed out which showed what lanes went to what ports. its been abit since i looked at it but it sounds like you got a pretty good idea so i not going to go find it (probably in the dell m4800 manual matching my dell m4800 configuration which is intel i7-4800mq with amd firepro 5100 (i believe).
anyhow so i dont need to have more lanes for the vcard to keep low latency for games like first person shooters like call of duty or battlefield where latency is important?
thanks for the info you gave and hopefully will give
thanks

 

I have some questions about upgrading a M4800 with the radeon pro WX 4150. (i7 4700mq, firepro w5100m, 16gb ram, 1080p screen, 256gb ssd, just puchased it off of ebay in refurbished condition for $500)

1. is it truly plug and play? like install the card and drivers without any modification required? Even if its a HP card? or will i need to flash the cards bios? if so, how?

2. do all of the video outputs work with the WX4150? (vga, displayport and HDMI)
3. does the WX4150 work with eDP and LVDS displays? (not sure if pascal GPU's support eDP) (has anyone tried the 5 reboot thing with a pascal GPU?)
4. does the internal screen work? any weird issues? does the laptop go to sleep when you close the lid?
5. do you need to run external software to control the fans with the WX4150? when plugged in and on battery? (with the latest bios?)
6. has anyone tested the quadro m2200? if so, do all of the video ports work and does the fan control itself?)

7. does the latest bios for this machine improve compadability with nvidia pascal cards?
8. are there any faster AMD MXM cards that could potentally work with this machine?
(i know about the copper shim, easy enough)

Thanks.

 

Woah thats a awful price, I've seen 7510's go for less.

1. Heatsink needs a shim
2. I believe some users had issues
3/4. Internal works with Enduro/iGPU if its LVDS, if its eDP it should also just work. Pascal GPUs only support eDP
5. Yes
6. Also yes, unsure on video ports but fan control is unneeded.
7. No
8. a full RX 560 MXM exists, but it's marginally faster. 5500M MXM apparently exists in the Zbook 17 G6, but it's near 100% a MXM B card.

 

Thanks for the info .
(also yeah its a bit more than id like to pay but everywhere else ive looked other M4800's are around the same price. (i live in victoria australia)

Just to clarify, the WX4150 needs the fan to be controlled by software, becuase the system doesnt turn the fan on and the GPU overheats? (like theres no fan speed corelation to the GPU's temp? is it possible for the WX4150's driver to control it?

Also is it possible to install the M4600 heatsinks into the M4800? i noticed on the M4600 theres a heatpipe going to the CPU fan from the GPU, hopefully that can help out with cooling the WX4150 if its main fan doesnt do anything.

Thanks again.

 

Oh $500 AUD, that makes alot more sense and is generally what I've seen lesser specced machines go for in your market, forget what I said previously thats a pretty good deal.

WX4150 needs fan control software as the laptop doesn't communicate properly with the GPU to know when to spin it up, its not possible to get it natively through any means I know of, but you can set HWinfo64 to start up at the beginning of your session and auto regulate the fans to the temperature of the GPU core.

I would assume no for this one, despite them being very similar. It should be possible (space and your skill deciding) that you can remove a heatpipe from that heatsink and thermal epoxy it to the heatsinks, I'm not very knowledgable in the subject of custom heatsinks, would be more of @TheReciever 's area of expertise I guess.

 

I see, so the M2200 (and M2000) doesnt have this fan speed issue? i just need to modify the drivers .INF file for it to work? does that also apply for the GTX 965M?

with the WX4150, i dont need to flash it from the HP bios to a DELL one for it to work right? (i dont have any other laptops with a MXM connector)

Has anyone made progress with getting pascal or turing cards to work with this machine? appareltly bios A25 solves something to do with the gpu.

Thanks

 

Both need .INF modding, but fan speed should work fine.

The HP card's don't have VBIOS's on them, they have a spot for a VBIOS chip but their actual BIOS is contained within the system.
