Power limit throttling help

Hi guys, I'm looking for some help on a problem I've been having with my 650rs (i7-6820hk with 1070gpu) I just got earlier this week. I posted a version of this issue in the owners lounge but I wasn't sure of what the problem was so i apologize in advance if this is considered a double posting. I think I narrowed it down now with what's happening to my cpu.

A couple days ago, I tinkered with XTU and MSI overclocking my system. By adjusting only the multipliers, I pushed it to 4.1ghz and it seemed to run fine temp wise with a couple benchmarks (several times each) - XTU, prime95, furmark, and the in game benchmark of Gears of war 4 (I was just testing for stability). Everything seemed fine until it crashed during the benchmark in GoW4. Afterwards, I noticed my cpu speeds would top out at 3.2ghz with prime. By running GoW again or any other game, I noticed my cpu speeds would spike up to 4.1 and back down to 3.0 over and over again. Temps were normal again... so I deleted GoW (found out some performance issues online) and reset my cpu settings back to stock even in the bios.

Now back to stock settings and all, I noticed with prime95, my speeds would only top out at 3.2ghz. After a couple minutes, I noticed power limit throttling spikes in XTU (see below)


I'm not sure if this was an issue before, I didn't have the box ticked for power limit throttling until today facepalm*

I don't have an idea on how to move forward now with trying to figure it out so I'm hoping someone could walk me through this. I know at the very least it means there's not enough juice going to the cpu, which I unfortunately now understand when you overclock, but at stock settings I'm pretty sure this isn't supposed to happen, right? Anyway, I appreciate if anybody can help me out. Thanks!

Oh and I'm running on high performance profile.

This is a common thing. The only one way is to get Prema BIOS for this model. So if you can return it and then rebuy from Prema Partner shop https://biosmods.wordpress.com/partner/ in order to get it. Furthermore maybe the donation for him will work too but, i don't know.

 

That's a perfectly normal clock for prime95 given your set long turbo power of 45W (the stock value).

Thanks for the replies!

So, with that said, I think I deserve a bigger facepalm/slap now that I didn't sleep much looking up more info... with what you guys said I'm assuming I can't overclock this model yet because of the limited bios options from Clevo/Sager...right? Hence the need for the prema bios... well this is embarrassing if it were the case. I was under the impression it was as easy as just adjusting the darn multipliers in XTU.

Furthermore on that prema bios, I got mine from LPC Digital. I know they're not listed on premas website but I've come across some posts here that they are. I emailed LPC to confirm just now to find out for sure but if anyone knows, please let me know! Thank you!

Raise the turbo boost power max and short turbo boost power max by 10 watts each and try again.

After extensive testing, I had to increase the turbo boost power max all the way up to 100W for the power limit throttling to go away. After that, it would current limit throttle so I increased it to 100A and that too went away. This is just to run it at the default multipliers of 36 34 33 32.

However, when I opened up a couple games (TW Warhammer, GoW4, and Fallout 4), I noticed occasional stuttering and FPS drops. I opened up afterburner and found out I've been power limit throttling on my gpu. My gpu is at default clocks too.

Is this normal? Correct me if I'm wrong but, it shouldn't be power/current limit throttling anything out of the box yea?
