Dell Precision M4800 - Can GPU be upgraded?

Hello all,
could you help me please, see this posting:
http://forum.notebookreview.com/thr...l-official-driver.831821/page-2#post-11067342

I had a Nvidia 1100 in my M4800, replaced it with a M5100.
After installing a game I restarted the laptop and everything went black.
Windows was not able to boot, only in safe mode.
I then uninstalled the AMD drivers, tried with multiple other versions but always the same: when trying to boot normally I get a black screen.

I now inserted the 1100 again and the laptop works again flawlessly, but with far less fps.

Does anybody know what is wrong here?
Should I buy a Dell WX4150 and install it, would it be worth it?

 

Switched the GPU in one of my M4800s - it could be considered partial success since the board itself is up and running - though I'm pretty sure it's a reflashed HP. The mainboard BIOS is apparently overriding the subsystem ID, so it is 0x15cc instead of the one defined in the vBIOS. Looks like some work may be needed to fix this.
Vanilla AMD drivers still cause freezes on the 4K display, so it's several GPU generations and 7 years when they are unable to fix this issue - I'm afraid, they've lost me as a customer.

 

This is normal behavior. You will always get an "identifier" for the motherboard in the subsystem ID for the GPUs installed in these systems. This is why an INF mod is always necessary when installing "unsupported" NVIDIA GPUs, because they specify basically the GPU+motherboard/system model combo together in the driver INF files. AMD seems to be more lax and leaves out the subsystem bit.

 

What would be a normal price for a Dell WX4150?
Where could I buy one in EU?


What is this card:

Would it work?

 

1) Yes, It would work because it's Dell Card with already flashed BIOS.
2) You wanna to pay twice from a normal price of WX4150 only because you can't buy HP WX4150 from USA EBay?

 

Well it woud be one easy GPU to buy for me, I have found no WX4150 on ebay germany from USA that includes customs
what would be the normal price for a WX4150 from Dell or HP?

 

you can use 1.5mm that came with AMD sink, and 1.5mm with Nvidia IHS mode I suggested, so pad size would be the same for both.

if you still have pads from your old GPU I don't see why you can't recycle them.

1.5mm pads are best.

it is important to know that pads are not made equal, and you need to match OEM thermal design.

in simple terms:

if pads transfer heat too fast, imagine its like your GPU central core is directly connected to them (VRAM's), so think of 80 celsious

this is (BAD) overheating may happen and chips can get cooked slowly overtime.

I'm attaching image where you (and others) can see visible variation in pad thermal designs. this is 1 set from m6800 heatsink. some are more porous than others some are more "wet" others are slighlty more "dry" ,you cant use lube (joke)

luckily m4800 sink design is much much simpler, and only need 1 type of pads with single rate of thermal transfer.

simple solution would be buying NEW AMD m5100 heatsink (perfect fit for WX4150) with brand new stock thermal pads sold on com bay USA, but it will run you @$30 delivered via global shipping. (eu-UK)

so if you intend to use aftermarket pads make sure they are OK not only regarding thickness but also thermal properties.

in example, I have just upgraded another m4800 with WX4150 using 2 pices of 1.5mm pads from old M6800 heat sink, and Nvidia sink, was plug and play, by the way, best driver for WX4150 can be downlaoded from here

last words, its highly important in air cooled systems to maintain balance between heat transfer and heat accomulation* to avoid possible subsequent detriment caused by such.

 

$100-150 dell, plug and play.

no fan control software/mods/imaginary problems/or OCD need to tinker are required, not sure why so many think they need fan mod for this card...

I have two WX4150 units both work perfect by themselves. one is made in china other made in taiwan.

their cooling start kick in is at around 70c maintained 50-70c which is perfectly normal for mobile GPU

$50-75 HP do not buy headache.

this card is sensitive to CPU thermal throttle or poer throttle spikes so use XTU Utility to pull down CPU frequency down to a stable condition.


just fun fact both cards report ASIC quality at 60% would appreciate if anyone can check theirs and tell me if its the same, just interesting to know.

ende gut alles gut.

 

it is highly likely if you have m5100 radeon, that your unit is LVDS, unless it was made in 2015.

in order to check if your machine is LVDS or EDP I found out that all you need to do is to put your service tag in support section of dell website.

https://www.dell.com/support/home/en-uk/product-support/product/precision-m4800-workstation/overview

type in your tag or click detect. follow link "System Configuration"

and there in drop down menue relating to Display you may see EDP1 = EDP board, LVDS will have non or something else.

thats How I learned to find EDPs

dont forget to Kudo the post to feed my EGO (joking)

I bet boris already preping a jack and re-write for this post too, haha

stay safe!

 

Hey all,

Just got my M4800 the other night for a killer deal since the previous owner couldn't fix it - anyhow ordered the HP WX4150 since the K1100m isn't the best. I also ordered the AMD heatsink. Looking forward to reprogramming it and getting it rolling.

Ordered HP unit via https://www.ebay.com/itm/HP-L17822-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
