    G4 Cube VRM

    Thanks indibit! Do you have a surface mount soldering set up with a hot plate? Or did you manage to make these modifications with just a regular soldering iron. Evan talks about how hard it is to get the board hot enough. I was going to try with just a soldering station since the SMD parts are...

    Lots of threads about VRM troubleshooting and some upgrades you can do on an existing card with new MOSFETS etc.

    G4 Cube VRM

    Look for a replacement for my blown C3. It looks to be a 150 uF 6.3v capacitor? Does anyone have a digikey/mouser/newark link for the proper replacement? Tested out my blown VRM and the 5v rail is shorted. Not sure which MOSFET is bad since they are in shorted with a DMM. Hopefully it didn't...

    G4 Cube VRM

    Thanks for the reply JDW. I believe evanboonie's start of a VRM replacement has the pinouts for the connector but need to reinstall Kicad to check.

    G4 Cube VRM

    Any suggestions for the best way to test an original VRM board? I have two replacements now for my “magic smoke” VRM I posted a bit ago. Should I look for shorts on the connector voltage pins in case there is a short on the motherboard? Or any way to test a board in isolation? I’d rather not...

    120GB SSDs in G4 Cube

    A mystery! What adapter(s) are you using and what exact DVD drive did you replace it with?

    G4 Cube VRM

    My VRM in a second cube I have is pretty toasty. Some bad soldering reflow and C3 is blown. This was in a cube I just picked up and magic smoke appeared from somewhere when I plugged it in. Is there a guide to test these somehow or troubleshoot bad components? Or does someone rebuild these? I'm...

    120GB SSDs in G4 Cube

    Yes. 9 in master and DVD in slave - DVD does not show up. 9 in slave and DVD in master - DVD does not show up. I verified that the master/slave pin on the 9 enclosure does change it's device ID in "More Info" but somehow blocks access to the DVD which is weird.

    120GB SSDs in G4 Cube

    Do you have a suggestion that is known to work? My #8 item is a 2.5” IDE to MSATA enclosure so nearly the same as an IDE SSD I would think. And for some unexplained reason it blocks access to the DVD-ROM. i don’t believe there are any 3.5” IDE SSDs(???) so you will need a 3.5 to 2.5 adapter...

    120GB SSDs in G4 Cube

    This is a pic of various hard drives and adapters I've tried with my cube over the past month or so. Here's a writeup I did for another site: I picked up G4 cube about a month ago with no hard drive. Here’s my saga for getting an SSD to fit in the limited space with the original cable and...
