[SOLVED] 2600x wont boost all the way

[crowsonjj]

I just got a 2600x, and have been bench marking it. With game boost on in the bios, the clock speed wont break 4.05ghz, but the cpu is supposed to go to 4.2. Anyone know why?

That 4.2 GHz boost can be achieve only if the heat is dissipating enough for that speed and enough power is delivered to the CPU.
Could you post your system components and temperatures while benching it.
Which bench program are you using?

I have an msi b450 tomahawk, 16GB corsair lpx @ 3000mhz, r9 390. I discovered through the ryzen command center that I can easily move the speed up to 4.2ghz, but the heat increase in huge. Im using a hyper 212 evo. With the 3.85ghz I was settling at 73c using prime95, at 4.2ghz it was going over 90c, I decided to settle at 4.05ghz.

on a side note, my idle temp is fluctuating wildly, between 36c and 55c(its under no load).

While running Prime95, what's the highest temperature you got?
It's OK to get high temps on Prime95 since it taxes the system in a way that no other app might do.

You could increase the Evo 212 speed, its fan might not running fast enough for the temps. You could change the fan curve in the BIOS.
Which case do you have?
Maybe hot air is not leaving the PC case in a timely manner.
When the R9 390 kicks in, it will be very hot in your case and you want to avoid it ...to keep the system performance.

My case is a phantek enthoo, It has one 200mm intake on the front, 2 120mm exhaust on top and 1 120mm exhaust on the back. As for max temp, when I had it at 4.2ghz, I think it was 95c.

Update: after running prime95 again with it clocked at 4.2, my computer froze shortly after reaching 97c.

That case is very good, so I don't think you will reach that temperature on normal use.
So you just might need to bump the CPU cooler speed when needed.

Yeah, my last cpu (i5-4590) would idle at 29c, and my 390 still doesnt get too hot even under load. Without going to a bigger heat sink or aio, I think that`s my only option.

What else it might be is that with the hyper 212 Evo, the vrms on the board might not be staying cool enough. One thing I've read is that tower coolers or water coolers don't allow as much cooling for the vrms. Basically, the stock coolers allow the cpu fan to blow air onto the motherboard vrms to help cool them. But the 212 sits up so high, it could be that all the air flow is to high above the vrms.

Maybe swap to the stock cooler or see if you can place a fan to where it can pull heat away from the area of the vrms and see if that allows the cpu to reach the higher speed.

You should use the BIOS to get a better handle on settings and get a higher overclock.
Overclocking apps are easy to use, but they might be applying to much voltage heating up the CPU when is not necessary.
The stock cooler is not better than the hyper 212 Evo.
You should also take in consideration that not all CPUs are build equally. I purchase two Ryzen 5 1600. Installed them in the same system and one would run at 4.0GHz (1.375v) with not effort, the other could not go beyond 3.7GHz not matter what I did. If I tried anything higher the system crash or wouldn't even boot at times.
