Re: Post your system.......

Heh, first gen i3/i5/i7s still pack a punch today, after 10 years from their first release.

Goes to show how sturdy Intel made their chips back then. I'd drop a 1156 Xeon in there if the board and...

Re: Bad Video cards - Reflow?

None of the chipsets I used 350*C on had issues after reflowing at 350*C. 200*c seems like a temporary fix, as I feel the chip doesn't get hot enough. 350*C is the default RoHS lead free solder...

Re: Bad Video cards - Reflow?

I've had long term success with that method on a lot of laptops. The only difference is I didn't need a IR temp meter. I used a 350*C automotive heatgun (Titan Tools 22400 in the US, mine is Kaufland...

Re: best cheap/free scores 1.1

Yeah, popping mosfet seems usual for 9800GTs but otherwise, I was suprised that 9500GTs do that too. Maybe there's something that makes them fail? At least my Inno3D 9800GT would pop FETs if the HSF...

Re: best cheap/free scores 1.1

Fixed the 9500GT 1GB that had a blown FET. Works fine, although someone did try a reflow beforehand. Replaced the old STONE 470uF 16v cap with a poly cap from a old MSI 775 board just to be on the...

Re: best cheap/free scores 1.1

Didn't have any. It was the UMA GPU (Radeon HD3100) that was bad. I threw it away though, but not before saving anything I could reuse. (CPU and WiFi antennas)

It ran a GTX 1050 Ti on that Athlon X4 840+8GB RAM combo, but that was long before I got the PC. (and I got it without the GPU)

Not even close. Anything beyond 200W would be already dangerous. EI-28 transformer.

Re: Gigabyte GA-N650SLI-DS4 motherboard not detecting PCI-e graphics card

These SLI boards usually have a bridge card (that empty slot between the blue PCI-E and PCI slots) and will exhibit these issues without them.

Oh, and that TSB45AB23 is just the 1394/FireWire chip.

Re: best cheap/free scores 1.1

Well, it's still a LCD display (OLED tech tho) nevertheless.

I'm already in process of ordering a whole new glass + display though. It's WAY too risky to remove the panel and change the glass....

Re: best cheap/free scores 1.1

I guess it's good, temps idle somewhere between 40 and 60*C.
