my fx 8320 not reaching 4.0 modo turbo, only 3.7ghz how to enable reaching 4.0 turbo my mother board is 78lmt usb3
 
That is actually fairly common - it is because it is enabling turbo for all 8-cores. It is only when using a couple cores that it will boost up to 4.0, supposedly.

The only way around it is the manually overclock, which you'll want to be careful with on that board.
 


I have that board, it's good for overclocking. I'm pretty sure these CPUs are able to overclock to 5GHz max.
But yeah, I think calculatron is right.
 


I have that board. It is good for overclocking dual core cpu's. It has 4+1 phase power. There are no good MicroATX AM3+ boards for overclocking. They don't exist. There are bad and worse. That board would throttle the heck out of a 8320/8350 if you tried to approach 5 GHz. The mosfets would explode in short order. You want to overclock a six or eight core Piledriver? Get a Sabertooth R2 not a toy board.
 


but board have 8 pin connector and heatsink on vrm i think could maybe bear oc 4.0 or 4.2ghz do you think?
 


I'm planning to OC a 6300 at around 4.6GHz, suggested by someone in the mobo section. Going to buy a MSI 970 GAMING mobo, you think it will handle the OC? Don't wanna fry anything, tight budget so dont want to damage anything. cant afford to fix.
 


i just wanna oc 4.0 or 4.2 and what voltages safes or turbo core reaching 4.0
 
Here's the thing about the FX CPU's, speaking from experience who have used and overclocked them. As soon as you reach 4.4 (average), the voltage bump required for the higher frequencies just isn't worth it. I even used the M5A97 LE 2.0, with only a fan over the VRM. There is no way a "cheaper" board can do any better, especially due to the high voltage required for the higher frequencies, from my testing anyways. If you somehow make it work, please share.
 


Okay, I'll just overclock to 4.4 or whatever speed that's safe. Would the MSI 970 Gaming mobo work? I'm guessing yes since you said 4.4 is the fastest safe speed.
 



MSI makes the worst AM3+ board you can buy. Google, MSI and exploding mosfets. They use sub par Chinese capacitors while most other manufacturers use Japanese components. A good board for the price is a GA-990FXA-UD3 R4.
 


Hmm all the reviews were positive from amazon reviews etc. not just MSI's site. They also look very nice with the red and black theme I wanted. I also saw a whole "page" i guess in the BIOS to overclocking so that was nice. Making overclocking easy.

But yeah I also saw the 990fx chipset. Though I don't know much about chipsets, I'm guessing the bigger the number, the better...

I mean all I'm overclocking for is to make sure my CPU won't ever bottleneck my GPU and also to help speed up render times. So maybe I don't need to overclock all the way to 4.4. I honestly don't know much about overclocking other than I just crank it in the BIOS and voila! Faster CPU! But then I saw people talking about voltages and mosfets (no idea what that is) and "VRM" and 4+1 power phase. I have absolutely no idea what these mean and if they even matter.

Maybe the only reason I'm buying a watercooler is to make my PC look nice. With my LEDs coming soon and a complete see through side panel, it just looks nice. But yeah I'll only be overclocking to make things a bit faster and so nothing bottlenecks.
 
Mosfet stands for Metal-Oxide Semi-conductor Field Effect Transistor. They are a part of the Voltage Regulator Module (VRM). The VRM controls the amount of energy your CPU takes in. The VRM also consists of Chokes and Capacitors which are driven by a "driver integrated circuit" (Driver IC - which can be a type of Digital PWM.) Capacitors store and help regulate the flow of energy, Chokes make sure that the electrical current stays within a certain range, while Mosfets do the physical work of allowing the CPU enough voltage. That said, mosfets are, by far, the hottest component of the VRM, and if a heatsink is present it is always attached to the mosfets.

A 4+1 phase means that four phases are dedicated to the CPU, while one is for the memory. As a general rule, more phases are better - it means that the VRM can handle more voltage, and is more capable of providing stable energy to the CPU. However, this is not always the case. Biostar's TA990FXE motherboard has a 4+1 VRM, but they used some quality components that can handle a 300 watt load. Meanwhile, there are some 8+2 VRMs that are "doubled" 4+1. That's, uh, a different story.

MSI's AMD entry-to-mainstream level motherboards were... ill equipped. Not only did they usually not have too many phases for their VRMs, but they had no overheating or failsafe features. So a lot of people were running hard overclocks on hardware not meant for it, which led to catastrophic failure. The 970 Gaming "fixed" a lot of issues, but some people still managed to bork the board when trying to run a sustained 5.0ghz. 4.4ghz should be perfectly fine, though.
 


Okay, thank you very much for your time and info. Still got a lot to learn for computers.
So I guess this board is good enough for what I'm doing then. Hopefully it lasts long enough, until I buy a i5 or i7. Probably not for a long time.
