msi laptop cpu throttling

Basically, I got this laptop
https://www.amazon.com/MSI-PL62-7RC...&ie=UTF8&qid=1502359734&sr=1-1&keywords=mx150

It's a i7 7700hq+mx150 ( I know it was a bad choice)
Basically when I game(cs, overwatch) the gpu temps are around 65-70c which isn't bad, but the cpu temps hit a constant 90c. It throttles and only hits like 2.7ghz.

How do I improve this? Do I send it back to msi to replace heatsink? Repaste the cpu? Undervolt it? Or so to a local tech store to change the heatsink?

 

Are you using cooler boost fans at 100%?
7700HQ should not get to 90C.

Download Throttlestop 8.48, go into FIVR settings, and enable voltage changes, and change CPU core and CPU Cache voltage offset by -100 mv.(-.100)

 

The PL series have a very mediocre cooling. Try undervolting the CPU.

Is there a way to upgrade the cooling system? How much does repasting help with temps?

 

Not sure but when I open a game cpu usage is immediately 100% and only hits 2.7ghz

 

open Intel XTU and make sure you set the Processor Core ICCMax to 100A

Also ensure your Turbo Boost Short Power Max and Turbo Boost Power max are both set to 200W

and finally, I know this is obvious but make sure you are on the High Performance plan in Windows not Balanced

 

@Phoenix This doesn't work on the 7700HQ. At least not on the HM*** chipset. Power limits above 45W are completely ignored. Also the unlocked Bios has no settings for power limit 1 and 2, only platform power limits. If he's lucky enough to have the 7700HQ on a good chipsets like the CM*, that has settings for power limits in the Bios, then this may work through XTU also., but usually there is no access to the MSR's as this is not an overclock SKU.

I spent days and nights trying to get the power limit to go above TDP but it won't on a HQ chipset. Overclock SKU will let you set power limits from minimum to maximum SKU_PACKAGE_MSR, but a non overclock SKU (HQ) is limited to maximum TDP limit (45W). It was this reason why I RMA'd my GT72VR for a GT73VR.

There was a way to bypass this by hacking the EC firmware with RW Everything, or changing a MSR that XTU and the Bios have no access to, but this isn't going to work on a MSI board with any HM chipset through any XTU setting, without messing with hidden MSR's in the EC.

I'm not sure if this applies to a 7700HQ on a CM238 chipset however (if such a thing exists).

7700HQ throttling can be 100% completely removed by underclocking the voltage by -100mv. Even Prime 95 small FFT with 8 threads AVX will not consume more than 45W after doing this at the maximum 3.4 ghz.

 

thanks for the clarification. So are you saying that by a simple -100mV undervolt it should prevent the throttling?

 

Yeah. That's what I did to my 7700HQ before I RMA'd it. I actually think I had it at -150mv. -100mv should be enough to stop ANY game or any benchmark besides 8 thread AVX/FMA3 from exceeding 45W. I know when I tested my 7820HK at 3.4 ghz with a -100mv, it did not exceed 45W in prime95 small FFT with AVX, but I think my 7820HK was running at 0.9v. (every chip has a different default VID however, so this is not a hard and fast rule. A crappy chip with a 1.3v VID at 3.4 ghz will exceed 45W).

He also needs to keep the chip cool. MSI GT72 and GT73 have excellent cooling. Lower end models are lackluster. No idea about the Raiders. The hotter the chip runs, the more power it will consume.

 

Should I contact msi? My friend had a same problem and they sent him a upgrade because of throttling

 

I undervolted it? But now it's around 72-80.... I might go for a repaste.

 

Repaste with liquid metal and repad with fuijipoly.

 

Repasting the GPU & CPU with premium thermal paste like Arctic MX-4 makes a huge difference with temps. At least that's how it is for myself, as I've applied the same thermal paste to my GT73VR-286UK model. I was experiencing temps of up to 90c with the i7 7820HK at full load. But now I'm getting temps up of around 75-80c for the CPU, and 75c for the GTX 1080. Depending on load.

Repasting with premium thermal paste definitely helps as these MSI laptops arrive with pretty bad thermal paste work. MX-4 lasts for a good eight years without diminishing performance before you need to repaste.

If you still find the temps are not to your personal liking after repasting, you could replace the thermal pads with 3rd party ones that supposedly cool the components better than the stock ones do.

 

Tk my man, I'll try this out.

 

Oh"well, not my first choice. Not the second,3rd or 5th.

Arctic MX-4 isn't silicone based.
