The Asus M5a97 LE R.20 doesn't have vrm heat sinks wile the non LE one has. The Asus m5a97 EVO r2.0 is a 6+2+2 vrm phase design. I think overclocking the FX6300 on the GA 78LMT USB3 would be fine.

The VRM's that feed power to the CPU will be one of the hottest parts of the motherboard, many times even hotter than the CPU itself. If you are overclocking an FX processor you ALWAYS want to get a motherboard with heatsinks over the VRM area of the board and preferably with at least 6+2 phases. To help things along, it is also a good idea to rig up a fan to blow on the VRM heatsink to help cool it down, or have two very strong fans blowing air over the heatsink from a CPU tower cooler. The Asus m5a97 EVO r2.0 is a good enough board to work in a mid level PC that will be doing overclocking.

You do not need a 6+2 or an 8+2 motherboard to overclock. Its not so much how many vrm's you have but it is the quality that also matters. You could have a motherboard with a 4+1 phase that overclocks just aswell as a motherboard with an 8+2 phase if the board with the lower phase count has better quality vrm's.

With this particular board though, i would not overclock simply becuase it has no heatsink.

Quality is definitely better, but not always at the expense of quantity. Sure you can overclock well enough on a 4+2 design, but even a high quality design with that few of phases wont be rated for 150+ watt operation for long periods of time. The FX-6300 6-core is a 125w TDP chip that will actually draw anywhere from 100-125 watts when under full load, with some mild to moderate overclocking that will put you probably close to the 150w mark when under load which means the VRM area will be stressed pretty hard and run quite hot. It can be done, and having a heatsink really helps, but it is much safer and easier to overclock to a decent level with at least a 6+2 phase design, or 6+1 if you dont care about doing anything special with the memory controller (which doesnt OC much on Vishera anyway). There is always the possibility that a 4+2 design may actually be crazy overbuilt and designed to handle 200 watts, but you would never see that on a sub $150 board, and anything designed for that much is going to do it better and use higher phase counts anyway so while it is technically possible for a rating like this, it isnt practically possible. Anyway, you should never push more than 125 watts on a 4 phase non-heatsinked board, cause that means you will be pushing probably 21-22 amps through each phase and it will definitely overheat with more than that, which is why you normally see 4 phase non-heatsinked boards only rated for 95w CPU's

For moderate overclock it is fine. I am rolling FX-8120 that is significantly more powerhungry (being mainly 8core procesor and on top of that buldozer varriant) on 4+2 phases overclocked 4ghz (29% overclock from stock 3.1ghz). It can go easy up to 4.2ghz altho my particular chip requires huge jump for such small increase so i just let it be smile.gif
For safe measures i believe 4.2ghz is pretty safe for FX-6300 and 4.4ghz for FX-4300. Over that i would not go really. Make sure you are not doing it on that 970 MSI mobo sicne it is known for VRM failures even on stock settings. I am rolling with asus m5a97 rev2.0 and it works like char. Friend is also keeping his FX-8320 overclocked at 4.2ghz on same motherboard. So yea its fine for entry level overclocking.

The biostar TA990FXE has a 4+1 phase but can handle an overclocked 8 core. Compare that to an msi board with an 8+2 phase that overheats with a stock clocked 8 core.
