Greetings everyone.


 12″ HP Elitebook 2570P



 Windows 10 

eGPU Gear

 EXP GDC 8.x adapter

 Gigabyte rx 580

 DIY eGPU Setup 1.35

Made my own DSDT files.

I've decided, after reading a lot about egpu mainly here, t0 create my own.
I found a refurb 2570p at a decent price. I use my laptop a lot away from home but didn't want to spend a lot on a gaming laptop (mainly due to gaming laptops being 15.6"+).
So here it is, my 2570p build. Upgraded the i5-3230m to a i7-3632qm, 240gb SSD + 1tb hd (caddy), all in a portable 12,5" laptop.
Now for the main part, the EGPU:
RX 580 4GB Gigabyte

Bought exp gdc due to price and here's all I've done:

Purchased 1.35 DIY Setup (Amazing program for egpu)
Created DSDT file easily with the guide here
Had some isues, but after setup as instructed by nando4, everything worked
Installed latest driver
Had some issues with freezing. Still have them, but after using aluminium cooking on the expresscard cable, that was reduced.
After everything I still had some fps drops on games. Even testing GPU-Z render was giving me weird FPS dips and after some investigation, I found that the memory clock was shifting a lot from 300-1550mhz.
So, for my fellow AMD users, I found this (weird and ugly) program that solved this issue and now I'm getting more consistent FPS ingame.
It fixes the clocks to max speed, so it fixed that issue:


I know we already have 2 or 3 2570p builds but I think it's important to give an updated case. I'll upload later on FPS results.
Here is userbenchmark:

Have you tried or would you recommend to power the RX580 with a DELL DA-2 instead? And would it work better with undervolting?

A Dell DA-2 is just slightly underpowered to drive my XFX GTS RX580 at full load leading to instability. This has been a recurring issue for video cards that near the 220W peak TDP requirement. For which I had two solutions:

1. For the RX580, use Polaris VBIOS editor to lower VBIOS TDP by 15W, then flash the modified BIOS.

2. Or my preferred approach. Restrict any single Dell DA-2 to supply 150W power, eg: slot (75W) + 6P = 150W, 8P = 150W. So for my XFX GTS RX 580 with a single 8P connector, use 1 Dell DA-2 to drive the slot, and use a second Dell DA-2 to power the 8P connector.  Dell DA-2 AC adapters can still be f ound for very low cost on ebay-US making this a cost effective, no fuss solution.

The beauty of this configuration is you can then upgrade to much more powerful video cards with 6P+8P connectors (300W TDP) such as a GTX1080Ti FE.

Refer to this thread for the required  DA-2 to 6P-to-8P extender cable + jumper pin needed for the second Dell DA-2 used in such an arrangement:

Good job. I am using 8570p with 660 gtx on win7. Is there anything this laptop can't do? Great machine.
