advice on atx or smaller system

cheers for the links. As far as the fans are concerned i feel an idiot as they were actually spinning. I was used to the sound of my old pc that i assumed they were not moving (what i had taken to be stationary fan blades were the fan case frame )

my system seems solid with the memory at 3333 and the cpu running as standard. However when i change the ratio from auto to anything higher than 35 then my system will not even boot. (so thats a small 300 htz OC)

however thats leaving the voltage well alone and just changing the CPU ratio etc. I had assumed i could run this type of OC without touching the voltage.

also what is SOC max?

The strange thing is that if i press the game boost button that applies a 400 booast to the CPU and that runs fine (even with the ram at 3333) - i dont know what options game booast changes - i know that it takes over the fans as they are then on full when i select game booast.

is the fact i am using a non x version of the 2700 a problem ie can they still be OC'ed and if so what is the minimum OC i can expect
 
About the Game Boost - go back into Hardware Monitor after applying it, to change the fan profiles. It should leave the rest of the Game Boost changes on. Which I think would be a CPU and RAM (XMP) overclock. Check voltages to see how they are doing.

Unlike 2600 v 2600X, the 2700 is said to not be able to clock all that well compared to 2700X. Still there might be some good ones around.

SoC means System on a Chip (think because the DDR and PCIe controllers are both on the same chip). Essentially you can increase that voltage slightly to help with memory OC stability. But try keep that voltage below 1.2v. If memory is fine at 3333, leave as is for now. Maybe later it might need a little voltage adjustment to help with the CPU overclock.
 
would it be best to leave my CPU as stock and just rely upon its own boost or overclock it.

at stock it usually fluctuates at around 3.4 but using HW monitor some cores boost to 4.1 (shows as the max value on the HW app)

however whilst gaming the 2700 cpu seems to hoover around 3.5 and thats about it. I game at 4K.

my using amd master i can put a gaming option overclock at 3.9 and thats with memory at 3333. It runs stable on games and cinebench. I select a fixed 1.25 v through amd master (i assume thats a safe voltage - the cpu temp does not go above 80 degress on cinebench at this speed and voltage and its cooler when gaming as well)

by doing that HW monitor shows a fixed speed of 3.9

1. if i use amd master at 3.9 will that stop the CPU from then boosting
2. For gaming is it best to simply leave it at stock and trust the CPU to booast when required or to run it 3.9 all the time when gaming


the reason i like amd master is that if i overlclock through the MSI bios it disables cool and quiet which i like to use especially if watching movies on the pc

i can then switch a gaming preset through amd master when i want to actually play a game

on the MSI MB B450 carbon pro there is a CPU bios option called Precision OVer Boost - its default is auto - should that be enabled. I assume this is different from the MSI game overboost which is also an option you can select (that adds 400 to the clock speed)
 
I've seen some people leave CPU ratio and voltage at stock and just enable XFR2 and PBO (Precision Boost Overdrive) with good results. Would experiment with that. Just using XFR2 and PBO seems to be the general advice with Ryzen now, though mileage may vary.


When it comes to cooling, I guess it's preference. I'd prefer to set a custom fan curve in the BIOS (once you've finished tweaking/overclocking) that will handle both idle and gaming without the need to click anything after that.

I think the default setting for AMD Cool n Quiet in the BIOS is "Auto". That might be responsible for enabling/disabling automatically depending on other changes in BIOS, and you may (I have no idea) be able to control this by choosing enabled or disabled instead.
