Unfortunately, one of my T-520s lost a motherboard, and I accidentally ordered a W-520 motherboard with the Quadro 2000 GPU by mistake. It does fit the T-520 frame, and will take 32 GB of RAM instead of 16 GB (which works for me, although it needs a different fan/heatsink, DC power socket and a 170 W power supply), so...
I've decided to keep it *IF* I can find a W-520 modded 1.46 (8BUJ25US) BIOS mentioned elsewhere at http://rgho.st/8JBjMm4mn (which appears to have had the file removed).
Were the T-420 1.52 (83UJ33US) and T-520 1.49 (8AUJ30US) BIOS available as well, I would be interested in those too to update my other systems.
If anyone has information on what the Advanced BIOS options are (more than just going into the BIOS and looking at the brief, but at times not too helpful, descriptions, I'd be interested in that as well.
My thanks in advance for any leads on this.

I'm going to give this a try with 32 GB (4 x 8 SODIMMs) of G. Skill DDR3L 1866 (PC3L 14900) RAM with latencies of 11-11-11-32 as I do heavy database crunching.
I have no experience with T/W-530 swaps into T/W-520's. Perhaps others can help you. Same goes for T/W-530 modded BIOS.
Others maybe able to point you in the right direction.
Okay, I actually had a different question. I was wondering if this modded BIOS happens to support Ivy Bridge CPU-s e.g. i7-3xxx. Probably not?
