Hello guys, my egpu is making me crazy! As i explained in my previuos posts my system is composed by: Acer Aspire 5755g i7 2.1 ram: 8gb igpu: Intel HD graphics 3000 dgpu: Nvidia GTX540m egpu: Asus gtx970 strix PSU: Thermaltake Hamburg 530W Adapter: PE4C v3.0 I removed drivers of dgpu and of igpu and I deactived dgpu via BIOS: I connected my egpu on pc and i installed drivers of igpu and latest desktop nvidia drivers. When i started windows Gtx970 was recognised with error 12. I used setup 1.30. Setting pci to 5Gb/s and performing a pci compaction, GTX970 was properly recognised. The problem is that, when i start windows, my system uses only the internal lcd trow intel graphics, even if the external monitor is connected (and recognised in the Device Manager) to egpu. When i try to start a benchmark, or a game or an application ( setted to be started with egpu in Nvidia control panel) the system freezes and BSOD sometimes appears. I've no idea what's the problem. tbalazs14 suggested me to use a quality PSU but the problem wasn't solved. Thanks in advance, Emperoraugust

I've changed PSU but the problem persists. If i force the system to use the external monitor there' s no change.

Thanks! In your opinion a thermaltake hamburg 530 W is good for my purpose?

Hi, my system is an acer 5755g with Igpu Intel 3000 Dgpu (deactived) GT 540M Egpu gtx970. Unbranded psu 400 W Two days ago I installed my egpu and the error code 12 appeared. I used setup 1.30 for PCI Compaction and egpu was recognized without problem. The problem is that when i start a software that uses the egpu (NVIDIA System Monitor or 3DMark for example) the OS Windows 7 totally freezes and i must press powen ON button to force shoutdown. Anyone can help me? Thanks, emperoraugust.

Hi everyone, i've a simple question. I've a acer 5755g with these specifications: Processor: Intel HM67 Express Quad Core i7 2630QM 2GHz Base, 2.9GHz Turbo RAM: 8GB iGPU: Intel HD Graphics 3000 dGPU: NVIDIA GeForce GT 540M It's possible to install a gtx770 to this laptop, or the system is too slow? It's necessary the setup 1.30? I think i'll buy PE4C 2.1 (or is better PE4C v3?). Thank you, Giacinto
