Throttlestop Experiments - Razer Blade 15.6 (2018)

I had some time to sit down and try several combinations of settings on Throttlestop. I thought I would share my results here. I welcome suggestions of other tweaks I should make.

The final columns show the FPS results for Graphics Test 1, Graphics Test 2, Physics Test, and Combined Test - all on 3DMark FireStrike.

All tests were performed on AC power with Synapse set to "Performance/Gaming." The RAM has been upgraded to 32GB HyperX. You can ignore the labels in the first column. Those were just my labels to keep the tests straight.

It looks to me like the sweet spot is the fourth one. I haven't pushed the undervoting any further because I'm concerned about diminishing returns.

I'll likely use the fifth setting when I'm on battery. I'm using those settings right now, and getting an estimated ~7.5 hours of use doing basic productivity work on battery.

 

how are you setting your turbo ratio? thanks

 

It's a setting on the FIVR screen.

You can find detailed instructions here.

 

This is helpful and interesting, thanks for sharing. After seeing this and testing it out, I've adopted the 64/3.2 setting for my own usage, it works nicely with heavy CPU gaming, like Path of Exile, keeping CPU temps in the 70s with very occasional peaks in the low 80s. Also, more consistent ratios, less power limit throttling and declocking. OP - please consider posting this in the owner's thread, as this thread will likely get lost in the mists of time.

 

I'm glad it's working for you. I posted in the Owner's Lounge as well. Good suggestion.

 

Something you could do is make your downclocked 3.2 ghz profile as an "alarm" profile that triggers at say, 80C for CPU. Below 80C it will switch back to default profile. You can set this in the options of TS (DTS alarm: 20)

 

I undervolted my i7 8750h (-155) and temps improved drastically but my cpu seems to throttle when it reaches 80c.

I thoight they are supposed to go up to mid/high 90s before they throttle.

Even weirder i was playing cs go before i undervolted and my temps would go as high as 98c before it throttled. So i don't know what's causing this throttle to 80c?

 

It's power limit throttling, not thermal throttling. It's a known issue with no solution yet.

 

Thank you are these settings something you can easily switch between or is there a way you can auto choose profile based on battery vs DC //?

Im thinking of doing this for work to get 7 hours and gaming so I don't burn my wrist.

 

Did you change the turbo for each core with same stepping? (Reduce 2 on all etc)

Also, does anyone know if in TPL, the MAX field for Speed Shift matters? Because by default it's at 38 but in the main window I set Speed Shift to 64, so just wondering if that MAX value does limit how far you can set in the main window.

 

The one in the TPL is the multiplier, you can set the max and min multiplier there , the one in the main window is to control the how the CPU should act, higher means more power saving, lower means more performance preferred.
