How to Use Throttlestop

Is there a thread where one can learn how to use throttlestop to OC a 940XM? Thanks.

 

Yes, there is.

 

What would be good settings for a safe OC on a 940XM?

 

Entirely depends on your chip. Some people can get 20x, others up to 25x; just keep your temps under 90c.

 

Yeah I finally figured out the issue I'm having. I'm throttling with my processor, I can tell while using Throttlestop and see the max temps coming in at 95C. How can I stop the heat? Should I get more external fans?

 

What TDP are you using that gets you 95c? If it's less than 70, then you need to repaste, if it's more, that's probably normal.

 

How could I check where my TDP is? And i also noticed that in game My Chip % in Throttlestop is dropping in 12.5 increments from 100 to 87.5 and as low as 50. That means my CPU is throttling right? And when this happens temps increase, so to fight against that should I try for a repaste? Or more fans? Sorry about all the questions. Thanks.

 

Ok, you need to read through the first page of the guide, you're not using it correctly yet. TDP is total power draw, and the setting that governs how much turbo your chip will use. If you haven't changed it, then anything else you did will have no effect.

 

Set the TDC to 60 and leave it there you will never need it any higher period.

Now set your turbo ratio limits to 17x across the board and test with a stress test program at stock TDP setting. Then lower it one watt at a time until the C0% (load) starts to throttle back from 100% I recommend running Prime 95 or run a video encode to get the cpu maxed out.

Then once you have figured out the tdp you REQUIRE for 17x on 4 cores. Bring the turbo ratio limit up to 18x across 4 cores. Naturally the cpu will throttle as the tdp isn't high enough. Simply add wattage back on the TDP again 1 watt at a time until C0% is once more showing 100%. This means you CPU has sufficient juice to maintain 100% load at the TDP set at that multi.

Now if your temps gradually increase you will find you might need to add a watt or two on to get the C0% stable so add when and if necessary.

I recommend to run HWinfo and set your fans to 100% when pushing CPU to max. This way you get to know the limits of both your chip and the cooling that cools it.

Repeat this process until you can take the multi no higher - ie once your temps climb beyond 95C after sustained periods of time. Reduce the multi and tdp.

This method allows you to know the exact amount of power your particular chip requires for a certain OC. For example I know to run 20x across the board I require 67W exactly for stable 100% C0% for as long as I want and my temps with fans on full won't exceed 70C.

Your chip however might require alot more or maybe if you are lucky a similiar amount however no chip is the same so you can't dial in someone elses settings.

Happy testing.

 

Ok, I just tried it. I had prime 95 up and saw my temperatures slowly rise to 98 and then my PC shutoff. This is why I hate doing this, it scares me to death, especially as I desperately closed prime 95 and saw my temps keep increasing. I increased the TDP but did not see any changes in the Cmod %, but I did see my C0% go from 100 to 99.5 occasionally. I had turbo rate to 17x on all 4 cores when I did it. Any help? Thanks.

 

It hit 100c at only 17x? You need to repaste.

The other thing is: Why are you overclocking? Some people really do need more power, but if you don't really and it scares you, just don't do it. You don't have to.
