Now this $50-? mobo might actually be worth playing with. Especially if it is the 755-A2! :thumbsup:

The ECS 755-A(2) uses a Semtech SC2643 voltage controller that drives the 2-phase CPU power supply. The maximum voltage for the Athlon64 is 1.55 V. This default voltage is set on the fly by the CPU and can be changed either in the Bios (use the modded Bios) or via certain Windows applications.
The SC2643 has a sense input that will calibrate the ground level for that voltage. This input is usually connected to a ground plane near the CPU. This calibration can be manipulated to make the SC2643 "think" the ground level at the CPU is higher than it actually is which causes it to raise the core voltage accordingly.

Oh yeah! that's all this board is missing as far as overclocking goes.

Definately a good choice for those who want to keep it cheap, goes well with a 3000+.

Ya, I was excited about this mobo when Dazz had pointed it out to me if you recall. (Ofcourse that was the crappy A1) Now the ability of this A2 has just made this inexpensive mobo solution really worth while for those unsure if they should invest in a A64 socket 754 now. Hell, you can game on this till nForce 3 250 hit's the shelves and plop all of the components into the new mobo if ya wanted. Even sell it on Ebay afterwards. :D

Great choice for budget minded gamers imho. :thumbsup:

Peace,

My buddy John and I are heading to a trade show in a few hours here in search of an A2. He's been wanting the board but everywhere he looks online, it's either the A1 or doesn't say what revision. So, we hitting the trade shows as vendors have ECS products in abundance. :D

Sweet! If you can post your results if you do find one that would be even better. :D Good luck in your search, oh yah and tell us if you do find it how much you paid. It's my understanding you can find some "Helluva Deals" at the shows. :D

Peace,
