MS16F2 + 2860QM + 970M - Possible Power Throttle?

Hi,
I have what used to be a Medion Erazer X6819 - GT683DXR) - MS16F2
I changed out the GTX570M for a 970M 6gb
Unlocked modded bios and vBios - which i havent overclocked myself
Added 16gb 1600mhz Corsair vengeance
I have since changed out the CPU from 2670QM to a 2860QM

benchmarks seem good when each part is tested separately but when physics are involved it drops frames dramatically
I also seem to be having issues with frames dropping in certain games - possibly when GPU and CPU are working hard together in CPU intensive games

CPU under stress sometimes hits low 90's C - briefly then drops back to 70's - low 80's C when the fan kicks in
GPU with the modded bios has its default clock @ 1038 all the time instead of 924 - temps are never over 75c
When i check the sensors in GPUz it looks like the gpu drops load and power draw briefly than ramps back up every few seconds

What im wondering is - could this be that there is not enough power to CPU due to GPU boost on all the time OR do i need to upgrade my power supply from 180W - 18V 9.5A to a 230W 19.5V 11.8A for a GT683DXR?
or is it possible my power supply is just maybe failing?

I do have a copy of my old vBios with NvFlash and BAT file - i was thinking about going back to stock settings ont the GPU to see if that helps

Thanks

 

I'm guessing its a power supply issue. Given that your GPU has a TDP of 100W, and your CPU a TDP of 45W (usually goes around 10W higher when turbo boost kicks in) you are close to the limit for your PSU when your CPU and GPU are under heavy load. If your BIOS lets you, try disabling Turbo Boost and running another set of tests to see if you get any throttling.

 

I disabled Turbo on the CPU and ran a couple of benchmarks and although the processor scored lower, the GPU scored higher than before so the overall total was higher
So next question is, can i upgrade the power pack to a 230W without damaging the laptop?

 

Yes, the laptop will only draw as much power as it needs. As long as the voltage is the same it will work fine.

 

That depends on if the laptop has an EC enforced power limit or not. Not even sure if that laptop was made back when the laptop could draw as much power as the Bios limitations allowed or not.

 

The bios are unlocked but not sure what im looking for - i think i have seen power limit settings but never messed with them

 

Would that be TDC (factory limit in Amps) and TDP (Factory limit in Watts) ?
These are unlocked and set at 0 = factory configured

 

MSI MS16F2's is not capped via EC firmware i used to own one myself, went from a 150w PSU to 180w myself a 230w PSU should work fine so long as the Voltage is correct to that of your original PSU.

 

Im starting to think the power supply is not right - it has decided not to work on a couple of occasions recently when the laptop was needing charged and ive noticed it getting quite hot, i have on a couple of occasions, changed the fuse but this morning i plugged it in and it started charging the battery after not working earlier as if there is a thermal shut off
Im suspecting my son has dropped it at some point while using my laptop and never thought of telling me

Having trouble tring to find a power supply with right connection - im assuming 19.5V would be ok instead of 19V?

 

I have ordered a Delta Power supply 230W 19.5V 11.8A 5.5 x 2.5mm barrel with no pin - i've read that 0.5V difference from 19V will be ok - did you use exact same voltage?

Do any of you know if I will have to alter anything in my bios? ie, TDC (factory limit in Amps) and TDP (Factory limit in Watts) ?

I've also bought some Noctua NT-H1 Hybrid Thermal Paste and 1mm Fujipoly Extreme X-e thermal pads and a Havit 3 fan Laptop Cooler to help with the temps if the extra power causes heat issues

 

Have you tried running throttlestop with unchecked bd prochot?

 

No I didn't, I was a bit worried about messing with that as my CPU was hitting 95c then dropping to 75 - 80 when the fan kicked in.
Could this cause damage if I uncheck it?

The power supply was scorching hot as if it was pushed to its limits every time the CPU hit turbo the GPU would drop power in GPUz Perfcap and give me frame drops

 

I even Reverted my GPU Unlocked/modded bois back to stock as the Boost was always on and Default Clock always showed 1038Mhz - seems like this helped a little along with disabling the CPU Turbo but the CPU is sitting 2500 instead of hitting 3600, the Laptop seems a little more stable

 

If you are afraid of using GPU and CPU at max then what was the purpose of upgrade?

Of course you should monitor temperature. And possibly AC to upgrade in the future. But your problem of throttling might be due to BD Prochot.

 

I have used Throttlestop only recently to test but havent really done alot of reading on it, im home from working away tomorrow, my thermal paste etc will be delivered and i can maybe push the laptops limits with the extra cooling from my Havit Cooler - i didnt have the cooler with me when i went away 3 weeks ago and ill get some reading done on the way home and learn more about using throttlestop properly.
From what i could see - the throttling i was getting wasn't thermal because the CPU dropped back to 75-80c and the GPU was 70c at most - so i automatically started thinking it was power issue, and that was reinforced by Arrrbol and a few others i have spoken to recently, also my Power Brick was knocked off the table recently and since that it has been really hot under heavy usage so im suspecting it may be damaged now

 

@Boomstick from 150w to 180w yes i did. Should of bought Kryonaught but the pads are right.

As for the throttling if your CPU was hitting 95c it would be throttling. Your best bet is to find away to control the fans there was a program i used that used RWEverthing to enforce a fan curve that might help you.

Using:Fan Control from Pherein with RWEverything Tutorail can be found here: https://forum-fr.msi.com/index.php?topic=3453.0

This will allow you to modify the fan curve so that it can manage heat better then that of what MSI sets if fan curve in its notebook.

Its what i currently do on my GT72-6QD, Turbo fan mode is great but really not efficient

 

I did try speed fan but it doesnt register my fan (there's only 1) - im gonna try RWEverything maybe tomorrow night once im settled at home (Still on a rig just now) i'll redo my thermals first and see how that goes - internet is that bad here i cant even translate that tutorial page! Haha

@hacktrix2006 - did you have to change anything in your bios to allow for extra power like TDC or TDP although im pretty sure they are for CPU?

 

No settings to do with power was applied to CPU or GPU in the bios, its a Shane I sold the old laptop else I would of tested my GT72-6QD's GTX970m in there now its doing nothing due to me upgrading to a GTX1060.

Do you think 19.5V will be ok rather than 19V?
- I've read it's within tolerances bit will generate more heat

 

Can't say to be honest as I didn't go that high.

@cuneyt1984 LOL you linked to my thread in MSI forum. My issue was temp based hence my request to svet. Also i was using a 770m not a 970m. Never got chance to test a GTX 970m as i sold the laptop in the end.

 

Wow, you are SECOND LIEUTENANT there.

 

Lol

Can we get Svet in here?

 

I ran Throttlestop with the BD Prochot unchecked, set it to 34T and Turbo disabled in Bios - its seems stable now and im getting good steady framerates in games now - Thanks James

I received my 230W power Supply - i've ditched it cos my laptop internals were whining a little and it shut down so i dont think it liked the 19.5V - but its running fine now on the original PSU
