can there be static/grounding issues with a exp gdc expresscard to a w520 laptop?
I run an EXP GDC 8.5c via express card on a w520 laptop, using a corsair rm650x, and a stock asus gtx 1050.
It runs pretty smooth, but occasionally glitches. I see checkerboard patterns flash occasionally when mousing over videos in chrome, or in games like this:
Today this timeline happened in the morning:
6:00 – i plug my headphones into the usb sound card … the graphics card resets itself
7:00 – i get up to get a drink, return, touch the headphones (tiny little earbud ones with a metal grid), get zapped a little … the entire laptop goes black and i have to hard reset it
7:15 – i adjust volume on the speakers plugged into the laptop’s audio-out, by turning their dial … ingame graphics do the flickering glitch while i turn, not when i try a second time
What is this? Is the EXP GDC not grounded properly and accumulating static charge? Is my laptop not properly grounded?
I’ve tried attaching a cable between the graphics card bracket and the PSU now, to see if that helps, but otherwise i’m not sure where to start with this.
Yes, in the following thread it was discovered the EXP GDC has poor EMI/pulse suppression:
You may consider adding ferrite beads to the EXP GDC, or aquiring a BPLUS PE4C or a modded US$7 PCE164P-N03 to connect to a EC port:
Wow, extremely fast answer and on point. Thank you!
I’ll try the ferrite bead thing today, and also see about giving the other ones a try. Two questions on that:
I’m quite wary of giving mods a try on my own. Are there places to buy a modded PCE164P-N03?
The BPLUS PE4C with expresscard is sold out on their official website. Can you recommend any other stores that would deliver to Germany, other than ebay?
Also, a small piece of feedback: I had checked the buyer’s guide repeatedly for information like this, and entirely missed that the “NO” in the table is a link. Maybe add a blue  link after it for oblivious people like me? 🙂
