The Fab

Why faulty isn't worthless

The fab is the heart of WeBuyBadRAM — an in-house repair and re-binning bench where modules everyone else writes off get diagnosed, fixed, and proven before they earn a second life.

The idea

A single error isn't a death sentence

Most resellers grade memory pass/fail and bin anything with a flaw. That throws away a huge amount of perfectly useful silicon — a stick with three bad sectors is still tens of gigabits of working memory.

We treat faults as something to diagnose, not fear. Most of what arrives at the fab can be recovered, repaired, or honestly re-binned — and what genuinely can't be saved is assessed and recycled responsibly.

What often comes back to life

Modules with a handful of bad sectors
Sticks that fail an aggressive overclock but run rock-solid at spec
Intermittent errors traced to a single bad DRAM package
Boards with tired solder joints that just need reflowing

The bench

Every module follows the same path

From the moment a box arrives to the moment a re-binned stick ships out, nothing skips a step.

Techniques

How we bring memory back

Four core techniques turn questionable modules into dependable, honestly-specced parts.

Bad-sector remapping

We map out failing cells and route around them to spare rows, so a module's stable capacity stays fully usable instead of being thrown away over a few bad addresses.

Reflow & reball

Cracked or cold solder joints under the DRAM packages are reflowed — and reballed when needed — bringing intermittent and no-POST modules back to life.

Extended MemTest86 burn-in

Every module runs multiple MemTest86 passes across moving-inversion patterns to flush out the faults that only appear under sustained load and heat.

Re-binning by stable speed

If a stick can't hold its rated speed, we re-bin it to the frequency and timings it runs reliably — honest specs on every part we resell.

Quality you can trust

Every module is tested before it is resold — no exceptions.
Re-binned parts are sold at the speed they actually hold, not their old label.
Repairs are validated with burn-in, never assumed.

Kept out of landfill

Working silicon goes back into real builds instead of landfill.
Reuse cuts the e-waste and the energy cost of making new DRAM.
Affordable, tested memory reaches people priced out by the crunch.
