I7 9700k boost mechanics?

[Kasper_MC]

Hi peeps

So, a buddy or mine has a I7 9700k in his system. He asked me to have a look at his system, because he was getting some bad image quality in games - with an RTX 2080 and 16 DDR4. We fixed his game by adjusting settings in game - so no problem there. 
But, I did install HWinfo and ran it while he played a couple of games. He is cooling his CPU by a 240 CLC, and through 40 mins of gaming, it never got above 62 degrees celcius. BUT! HWinfo showed that it shortly in the beginning, boosted to 4,7 ghz and then after 30-40 secs settled at 4,6 - it never saw 100% usages either... Intel says "boost up to 4,9ghz - is this normal?

Or is there something to do - without overclocking. I know - it's a k-skew - but he would prefer not to overclock it, since he doesn't feel safe about it. 

My own Ryzen 5 2600X also has the "max" recorded in HWinfo, after a gaming session, at about 4,8 ghz - which I know it can't hit (it's running 4,1-ish). So is it HWinfo that's just not precise enough?

That's only on a single-core load. When you're playing games, more than one core are in use and the boost-clock is reduced -- the more cores are in use, the lower the boost.

Yes. 4.6 is the all core turbo. If all cores are in use, that's as far as it goes. This isn't too obviously posted around, but it can be seen at link below for example.

Not seeing 100% is also normal for gaming. The game will only take as much as it needs. If you see over 50%, you've already loaded all cores. Anything above that is in the small bit extra that hyper-threading gives you (similar applies to AMD SMT). Basically Windows CPU usage reporting sucks and is a relative opportunity indication, not work done.

It's not necessarily hwinfo but the system reporting itself could be off. Make sure you have latest mobo bios, and latest version of hwinfo.

If ur cpu really is only at 60 u can just go into the bios and just put 4,9 on all cores should be stable for 90% of all chips ^^ But like the guy before me said the stock boost for all cores is only 4,6

DOH! Ok, skip that part.

Ok, thanks guys. That clears it up  This community is awesome - I rarely have to get frustrated with researching myself for ours to figure shit out... whenever I get enough of technical jargon-gibberish, I just ask in here

Yeah, I've tried to convince my buddy to OC the damn thing... but no... he doesn't feel safe with it / doesn't think it's worth it... So I would have loved to solve the issue that way, but unfortunatly it's not my PC
