Header says all. What say you?
Honestly, it all depends on how much you want to spend, temperature target based on your desired clock speed, and the case you're using.
Also what ram/mobo you're using helps to determine any potential clearance issues.
Used the stock cooler on my 2400G
I got mine at 3.6 Ghz. Going for 3.7 Ghz on stock next. Not looking for extreme OC but taking baby steps. Alarm set at 70C.
So far so good.
Voltage increases will up your temps the most, so keep your voltages down and see how far you can go.
Seen performance improvement at 3.7 Ghz. Stock voltage and cooler. Think I'll sit on this.
Now at 3.75 Ghz and the voltage hitting close to 1.4v. It's stable but is it safe? Temps still under 70c threshold. Showing 46c-50c average.
1.4v is ok and if those temps are during high cpu load, then they are ok too.
IMO it not worth adding a lot of voltage to just buy a little more speed, there is a sweet spot where a little more voltage gives you quite a bit more speed, but after that its tons of voltage for small improvements. My 8700k is stable at 4.9ghz at 1.28v, 5.1ghz needs 1.35v and 5.2ghz needs over 1.40v, so I just run it at 3.9ghz, 0.12v+ for 0.3ghz is just not worth it.
So an increase of 0.2v+ for 0.25 OC increase seems excessive? The voltage is on auto.
Well the 2200g turbos to 3.7ghz, so 3.75ghz is only really a 0.05 overclock. Don't use auto voltage, start by trying to find the lowest stable voltage at stock speeds, then increase the multiplier until it becomes unstable, then increase the voltage until the overclock becomes stable and repeat. Use cpu-z to stress test the cpu to determine if the overclock is stable and check your temps.
You mean it won't turbo to 3.95?
Base clock 3.5ghz
Turbo boost 3.7ghz
It will only turbo to 3.95ghz if you have overclocked it to that.
So if I OC it to 3.70 Ghz it's not OCed?
In other words... turbo boost will not kick in?
Ok, learned something about OCing. OCing disables turbo boost but recommended to turn TB off in BIOS. It's locked in at 3.7 Ghz and I'm done.
Yeah I disable all the auto clocking stuff and just lock my clock and voltage. My 1700 is stable at 4.0GHz with 1.375v. I run at 3.9GHz and 1.35v just for longevity reasons. 1.4v seems pretty high to me, I wouldn't recommend that high for constant usage.
Ok, I'm back to stock. Seems I don't get how to set and lock the vcore voltage.
I'm not going to take a chance.
You should be able to type the voltage in, click on cpu voltage in the bios and type out the voltage you want, including the decimal point.
Ok, if I do that what do I start with?
Never mind, found the problem. According to the article I found, my mobo has a poor vcore voltage regulations. At any amount of OCing the vcore voltage will rise to 1.4v. Manually setting the voltage did nothing.
At stock it stays under 1.2v. Both the CPUZ and AMD Ryzen Master confirmed it.
Yeah if it's a cheap board I wouldn't mess with it. Doesn't seem like you have super demanding use cases anyway.
