Re: Phil’s latest video - Voltage Blaster

That design is pretty nice, but you can have problems when you have very weak -12V line. Because a linear regulator wastes the entire voltage drop as heat (efficiency below 42% in that case). To achieve better efficiency -5V could be generated from positive voltage with charge pump like LM2662 or …

Re: Keep GeForce 4 to cards from dying

Working powered mainboard, spark off my finger, no image, dead :P that happened in my case BTW this was a cheap OEM board. Properly designed hardware usually haves some kind of ESD protection, either in internal chip design, or externally like TVS diodes which can absorb ESD. Of course it can still …

Re: Keep GeForce 4 to cards from dying

ESD is not a serial-killing monster, I haven't lost anything to ESD and I haven't used an ESD bag in years. I lost hardware to ESD twice: first time it was SiS 530 mainboard, it stopped working right after a spark went on some data lines, and second time it was Commodore C64 CIA chip, which had one …

Re: Dual PIII-S Tualatin 1.4GHz, GA-6VXD7 Via 694x, 2GB PC133 CL2, Radeon HD4650. Source games in 1080p

Thanks. BTW I resolved my FSB and voltage issues: FSB switching works fine, I just mistaked JP1 with JP2... :) to fix voltage, i had to bridge appropriate VID pins to ground. I followed the datasheet of mainboard's VRM https://pdf1.alldatasheet.com/datasheet-pdf/view/82527/FAIRCHILD/RC5057M.html It …

Re: Dual PIII-S Tualatin 1.4GHz, GA-6VXD7 Via 694x, 2GB PC133 CL2, Radeon HD4650. Source games in 1080p

I decided to try Steam, HL2 and CS: Source. January 2019 Steam version works fine on XP, modern versions would probably work with Win 7 installed. Some Source games have SSE2 check, i found it simple to remove by copying filesystem_stdio.dll from legitimate 2015 Garry's Mod copy. CS: Source gameplay …
