M17X r4 - gpu upgrade Quadro RTX 5000

[Ollie87]

Good morning all,

 

System Spec

• Unlocked bios A12
• CPU - 3940xm - OC level 3 (padded using 11.4cfm fan with liquid metal)
• PSU - 330w
• current gpu - Quadro RTX 3000 6GB (previously 980M)
• Ram - 32 gig corsair Vengeance
• running on SG mode
• standard 60hz screen (i have a 165hz 2k panel waiting to install when i am brave 40 pin connector)

 

Ok, i have decided to upgrade the laptops GPU one final time, i have installed a DELL version RTX 5000 16 gb that i picked up, installation seemed to go fine. i had to take off a slight bit of the heat sink end to allow fitting to the card, the card shows in bios and in device manager, the issue stars with heat, i am running a alienware m17 x r4 gpu heat sink that is 3 pipe, i am using artic mx4 thermal paste, the temps slowly rise to 100c , ive tried running the fans at full speed and it does not make any difference to heat dissapation.

 

currently unsure if the drivers are causing the issue or the heat sink is no good for the card, very much at my witts end on this one, is there anyone out there who knows more than i do, i did consider undervolting the card itself, but as im unsure why the cooler is not working to cool, i also have a KLIM pad cooler with 4 x fans.

 

on the first time i switched off the system and rechecked the thermal paste the card felt very hot but the heat sink end did not feel as though it was transferring the heat along the pipes ?

 

has anyone else had a similar issue. any help would be much appreciated.

Ok after a strip down I've noticed 2 chips/ resistors that are sitting proud and in wondering if these are causing very low heat transfer to the heatsink itself ? I will look to Dremel the heatsink to slot these in better

No good, still have heat rising up to the 100c mark, I will proceed to try and undervolt the card.

 

I have realised I have made an error, heat sink was cut, I have just ordered a replacement, I did not realised these contained liquid, I will look to the chassis to allow an uncut sink 😔 that can be the only cause of the heat not transferring I assumed they were solid copper.

Very nice upgrade.

 

I believe MX-4 is an outdated thermal paste. I have an RTX3000 and with MX-4 and PK-3 temps were a problem. I switched to PTM 7950. Now the gpu tops at 75 degress with the hotspot getting to 84. 

 

I have an AW 17 so it uses the stock fun curve.

If its not the heatsink itself you might look at the pipes!

Just for reference....

 

[Ollie87]

thanks for the video, i never realized the pipes contained liquid, stupidly i cut the ends off to fit it into the chassis 😅, im waiting on a replacement i will need to look at this better, the heatsink on the card hangs over slightly by about 10 - 15mm from memory 

[Ollie87]

Ok, so I have fitted the new replacement heatsink and it is keeping it cool, I need to work out a way to fix down the heatsink without butchering my case as the x spreader is off slightly

[Ollie87]

[Ollie87]

I managed to use some metal trunking lid at work and made a metal plate using the original spreader for the screw holes, I have some anti conductive heat resistant paint I can use on it, I will test this later tonight 

[Ollie87]

Ok, so all is looking good tests nicely heat is not majorly bad I will look to replace the paste with a pad, the thermal paste is messy as I've only added to what was there, but in a nutshell it works but the card is larger than the Rtx 3000 so I'm down to one SSD, need to find a bigger SSD without costing me a small fortune 

[Ollie87]

Hi all, having power delivery issues I think, running on max settings for example on dead by daylight 2 with ray tracing enabled I should be getting around 55 FPS, shortly after the drivers crash then causing the GPU to show 0C in hw info.

 

I will look to downclock and reduce the millivolts but MSI afterburner is a bastard to get the controls unlocked.

 

Does anyone have any knowledge to shed on this ? Didn't have as much problems with the Rtx 3000 

[Ollie87]

so far had no luck bypassing locks on MSI afterburner, i can only assume its to do with the vbios on the quadro rtx 5000, voltage remains locked on afterburner, if anyone has any ideas please let me know, i will look to try in a few games today to see if this is viable, temps seem ok, i have since used a grizzly thermal strip, my idle temp with increased fan is around 45c - 49c - under load around 76 to 82c, i may swap it out to grizzly thermal paste as im sure i was achieving lower temp with paste.

 

i have since removed silicon pads and used silicon paste instead, i did however notice the wattage on the card must of spiked to 114watts under high load, so im now wondering if its the spike causing the instability at higher graphical settings.

 

if this continues i may have to accept defeat and change the card back to the rtx 3000 😮‍💨

ok, tried a different game - looks like i never reached the thermal limit but i get a game crash when playing into the game, i do have a feeling the power delivery must be the issue at hand i think...
