Q: Is it possible to unlock disabled cores on the AMD FX-4300 CPU, or unlock additional 4 MB of L3 cache?
A: No. This processor does have 4 disabled cores and disabled L3 cache, but there is no known way 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-4300 close to 70 degrees and higher is not recommended.

Q: I have an AMD FX-4300 microprocessor. Can I upgrade it?
A: Probably yes. CPU compatibility is determined by your motherboard. Please see resource for CPU support list for your board.

AMD cuts prices of desktop CPUs
May 01, 2013: Earlier this week AMD announced new processors, expanding the line of high-end FX CPUs with quad-core FX-4350 and six-core FX-6350. It's not uncommon for AMD to lower prices when launching new products, and this time it was not an exception. Based on the latest official AMD price list, the company cut prices of ten A-Series and FX-Series chips by as much as 19%.

AMD plans to cut processor prices, launch A4-4000 APU
Mar 22, 2013: AMD Richland APUs are scheduled to launch at the beginning of June, at about the same time as Intel Haswell desktop CPUs. According to DigiTimes, prior to the launch AMD is going to reduce prices of FX microprocessors and A-Series APUs. The prices will be dropped by 8% - 15% on the following SKUs: FX-4300, FX-6300, FX-8320 and A-Series A6-5600K. It is possible that we may see lower prices for other APUs as well.

AMD introduces second-generation FX processors
Oct 23, 2012: AMD today introduced second-generation FX-Series microprocessors, based on Piledriver microarchitecture. The released lineup consists of 4 products, having 4, 6, and 8 CPUs cores, and operating frequencies up to 4.2 GHz. The fastest processor in the series, eight-core FX-8350, has up to 15% higher performance than the former flagship FX-8150 model. Three other CPUs, FX-4300, FX-6300 and FX-6320, also offer better performance than their first-generation counterparts.

Prices of upcoming AMD FX microprocessors
Oct 18, 2012: Less than a week left before the launch AMD FX processors with "Vishera" core. The new processors will be faster than older "Zambezi" CPUs, although it remains to be seen by how much. The performance will be one of the factors determining success of new products. Another factor will be how well they are positioned against Intel Core i3/i5 lineups, and against AMD's older FX models, and this directly relates to their pricing.

AMD A-Series to launch on October 2, FX-Series on October 23
Sep 25, 2012: While Intel is almost done releasing new desktop processors for the rest of the year, AMD has only started. Next month we will see new lineups, based on the latest AMD Piledriver microarchitecture, which is a tweaked for better performance and power consumption Bulldozer architecture. A-Series "Trinity" Accelerated Processing Units will target budget / mainstream segments of the desktop market, and, according to SemiAccurate, they will be introduced on October 2.

Pre-order prices of AMD FX "Piledriver" CPUs
Sep 20, 2012: Next generation of AMD FX microprocessors is around the corner. Built on "Vishera" design, new FX chips will have from 4 to 8 CPU cores, and pack as much as 16 MB of combined L2 and L3 cache on a chip. The CPUs will feature better performance than the first Bulldozer models, partially due to more efficient "Piledriver" microarchitecture, and partially due to higher stock frequencies. The FX processors will be available in October, while some reports place the launch as early as October 1.

Specifications of AMD FX-4300 series processors
Jul 18, 2012: Leaked AMD roadmaps from February of this year indicated that the company was planning to launch second-generation FX microprocessors in the third quarter 2012. New processors will be built on Piledriver (enhanced Bulldozer) micro-architecture, which main goals were to reduce power consumption and improve processing efficiency. Based on the reports from Fudzilla and Digitimes, the FX processors are now scheduled to launch in the 4th quarter, presumably in late October. Details of upcoming eight-core CPUs from FX-8300 series were revealed by Fudzilla last week. This week they published specifications of quad-core FX SKUs.
