I have to report another working Setup
- Acer Aspire 3820TG
- switchable Intel HD / ATI 5650
- i5-450m
- 8 GB Ram
- PE4H 2.4a + PM3N
- EVGA GeForce GTX460 FPB
- psu: SilverStone SST-ST45SF (450W)
- enclosure: 3R SYSTEMS V20
Switching between eGPU & dGPU is done via
BIOS-Mod, TOLUD is 0xA0000000 with dGPU disabled.
Still have some work left:
- solder full size mPCIe-slot (PM3N is currently in half size wifi slot)
- connect SWEX to power button
- wire internal usb hub & dvd drive
My first psu was too weak (+12V1: 14A, +12V2 - 10A), the silverstone has enough juice (36A). The GTX460 requires 24A.
Now it's time for some statistics
GTX460 @ x1.1Opt (stock clocks):
