I was able to use a 3700+ in my v2 shuttle sn85g4 with no problems.

How about Mobile Athlon 64s?

Has anyone had success with Mobile Athlon64 CPUs in the SN85G4v2? Many of them are Revision SH7-CG, CPUID 0F4A, same as the desktop 3700+ CPU. Note that you will definitely need a shim to use a mobile CPU with the SN85G4v2's ICE cooling module.

Some Mobile Athlon 64s will work

I bought a Mobile 2800+ (AMN2800BIX5AR, stepping CAABC) just for testing. I expected this CPU to work in my SN85G4v2 with BIOS rev. 23H, since the BIOS had microcode for this processor's CPUID (0F4A). Well, it almost worked. This chip should be clocked at 1600Mhz (200Mhz x 8), but I had to force it to x7 in Setup to make it work.

Good news for Mobile Athlon 64s

I bought a Mobile Athlon 64 3400+ (AMN3400BKX5BU, stepping CAB2E), which is detected perfectly by the 23H BIOS. The only manual BIOS setting required to make it work fine is to set Vcore to v1.375 (chip is rated at v1.35). Leave all other settings at "Auto," and it works fine. I think this was probably the issue with the 2800+ I tested previously, though I never tried bumping up Vcore with that CPU. Also, this likely means the 4000+ will work as well, meaning you can put the fastest Socket 754 ever made in this system.

With any of these Mobile A64s in your Shuttle, make sure you get a shim to go between the mobile CPU and the Shuttle's ICE unit. If you don't, it will not only likely not fit properly, but you run serious risk of crushing the CPU core. The only shim I can still find is the "Mobile Pad" from MSI Computers.
