Re: Post your worthless and/or pointless repairs

remember 0805 4-pack resistor... so basically four 0201's next to each other!

Re: repairing traces...on a fine pitch board?

Yeah, definitely, though repairing this module would go with the above module and the number of 2G modules would be even once more...

Anyway, this machine with three 512M modules will not get...

Re: Post your worthless and/or pointless repairs

FSCK there's no way I can solder wires around one resistor of an 0805 4x resistor pack... or anyone think this is even possible without shorting out the adjacent pins? LOL...

Re: PCIe x16 socket replacement / desolder / rework

Cutting was the preferred and even common method for even old DIPs even as small as DIP14 when the value of the IC was less than of the board. Solder suckers just do not remove enough of the solder...

Re: Getting lucky mixing DDR modules?

FSCK.

My DQ45CB will run 2x2+2x1 = 6GB but fails with 3x2+1x1 = does not POST or corrupts RAM When it does boot, it reports 2x2+2x1 in BIOS insisting "dual channel" but fails OS/memtest boot.

Re: PCIe x16 socket replacement / desolder / rework

Yeah cutting is the typical method, though still could induce inadvertent damage to the board since the plastic is still quite hard and could apply considerable and damaging force to the board while...

Re: Kind of a different question...

if it's a true ground pin why doesn't #%&*$ offer a 3 prong head for that charger?

But even if they do, where's that Y capacitor? Is it in the head?

Re: PCIe x16 socket replacement / desolder / rework

Even regular PCI and AGP sockets suck too... Probably the x1's have better luck...less pins, less to go wrong.

BTW does that board still boot after the removal, or was it trash to begin with?

DDR2 resistor packs... 0804?

Are those typical resistor packs on DDR2 modules 0804 (2010 metric?) 22Ω x 4?

Re: repairing traces...on a fine pitch board?

It sticks!

That's a 30AWG underneath that blob, and a 10 piece under the board.

Fortunately the tracks were relatively far apart, and only one track.

Re: PCIe x16 socket replacement / desolder / rework

Probably the same response as to changing a DIMM socket -- too many pins and the track/PTH are getting weaker and weaker...

Of course the slots are available to buy - to populate unpopulated...

Re: Post your worthless and/or pointless repairs

True I'm debating whether or not I want to sacrifice this 512M DIMM in case it too could be repaired, though technically sacrificing it for a module 4x larger is an obvious choice...

Would be nice...
