AMD FX-4100 is a desktop microprocessor, featuring new (at the launch
time) Bulldozer microarchitecture, 4 CPU cores, very high operating
frequency and unlocked clock multiplier. First details on this and
other FX-Series CPUs surfaced in as early as May 2011, and they were
confirmed in September by basic specs, found in a CPU support list on
Gigabyte's website. Also in September, some online stores started taking
pre-orders for this part. The FX-4100 was launched on October 12 along
with 8-core FX-8120 and FX-8150, and six-core FX-6100. Introduction
price of this CPU was $115, which was comparable to a price of Phenom
II X4 955 Black Edition.

Detailed side-by-side comparison
Q: Is there a way to unlock disabled cores on the AMD FX-4100 CPU?
A: No. This processor indeed has 4 disabled cores, but there is no known method to unlock them.
Q: My processor is running 55C under load. Is this normal?
A: Safe CPU temperatures are 60 degrees Celsius and below. It may
still run fine with CPU temperatures, exceeding 60C threshold by a
few degrees. Running the FX-4100 close to 70 degrees and higher is not
Q: Is it possible to upgrade my AMD FX-4100 microprocessor?
A: Probably yes. CPU compatibility is determined by your motherboard. Please see CPU-Upgrade.com website for CPU support list for your board.
