Hello, I had just a breif question.
Is Lenovo's Torpedo A75 Chipset board in the Z575 strong enough to support amd's A8-3500M, or greater model FS1 socket APU's? mine is currently equiped with the A6-3400M, I was thinking of grabing the A8, but first wanted to check if Lenovo offered a bios with the support for said APU, and if 2nd, the VRM on the Torpedo would deal with the extra ALU's of the A8 (400 over the A6's 320).
Second, has lenovo, or anyone released a 3rd party program to grant the user access to the fan profile of the cooler? I would like to keep it at a higher speed for use while rendering and other taxing work.
Thank you, for your response.

Regarding your first question.
I have Z575 here that came with A8-3500M factory installed. So Lenovo BIOS definitely supports 3500M officially, and VRM should be enough as well.
(ignore the higher clocks, I OC'ed it slightly)
Anything above 3500M should also work (in theory) as the stepping of new APUs was unchanged. Still all APUs above 3520M have TDP of 45W instead of 35W, so if they do work you might see temperature increases, but I think that unless you overclock stock cooling should be able to handle it.

Thanks for the response, I also run my 3400M above spec (2,000mhz full time at 1.00v, factory speeds being 1,400mhz @ 1.075v.) these APU's are incredible units and I had noticed that some of the Z575 units came equiped with the A8's.
Thank you for your resonse I will pick one of these chips up and cross my fingures. Now to find my tube of MX-2.
