P771-DM1-G 6700 non-K power limit throttle /BIOS?

Hi all,

I have a P771-DM1-G with a non K 6700 that is power limit throttling when all cores are in use. I've done nothing to it except undervolt by 120mV using XTU. Returning that to zero makes no difference. Does anyone know how I can prevent this from happening? As you can see from the accompanying picture my temps are fine during Prime 95, and the fans aren't even seriously spinning up.

Is there anything I can do to solve this using XTU or Throttlestop?

I have a stock Clevo BIOS because there is no Prema partner in the Netherlands and I had no idea the stock BIOS was so limited. I've started a "conversation" here with Prema but he must be super busy, I haven't gotten a reply yet. Does anyone know if there is a way to still get an unlocked BIOS? I wouldn't mind paying/donating at all, just bummed by finding out my CPU throttles after specifically buying an expensive desktop CPU based system.

 

OK actually it seems I figured it out. After googling some on power limit throttle, I found a setting in Throttlestop in the TPL windows that said "clamp" under "package power limit". At the expense of 6/7 degrees temp during Prime 95 (but still with little fan use) I now have all cores running at 3.4GHz during full load! That's all I wanted, the full CPU available when necessary!
Hopefully this helps someone.

Still looking for an unlocked BIOS though, tips welcome!

 

What a great program by the way, Throttlestop! It's a little hard to figure out what's what for someone with little experience with this but it's really feature rich and ergonomic!

 

Keep using Prime95 and your CPU will be fried sooner than later.

 

Thank you, that is very helpful.

I don't mean to be using it at all except as something to max out the CPU briefly to figure out where the throttling is coming from. Seeing as I found it, I most likely won't ever be using it again. Besides, what people on here seem to be doing with benchmarks is way, waaaaay beyond anything I'll ever throw at my system.

 

Prime95 converts your CPU into barbecue chicken and so does Furmark for the GPU

These 2 tools do not really create a usage scenario that a normal or even a power user would experience on his system.

Use AIDA64 stability test and have HWINFO sensors only running on the side to check CPU temps and clock speeds in real time

Let AIDA64 run for 4-5 mins to get the max temps

I'm on my cell phone right now. once I am in my laptop I will check your settings brah

 

Thanks, I'll look at that! It seems I've got it figured out for now though. This is what AIDA/HWInfo say:

That's with fans still being pretty quiet.

 

Yes the non k also comes with a lower stock TDP than the K so it will back down sooner by design. Raising the limit is overclocking of a sorts just so you are aware.

 

@Sanderxpander

Ok I just had a look at your settings

1) Increase the Turbo Boost Power Max to 120W
2) Increase Turbo Boost Short Power Max to 120W
3) Decrease the Turbo Boost Power time Windows to 1 Second (This will allow the CPU to bump up to the max Turbo Boost faster with no lag)

do you agree @Mr. Fox ?

PS: I don't know why his Turbo Boost Short Power Max is greyed out

 

No point having the boost slider unlocked when the short boost is disabled.

 

But the thing is if I don't "unlock" this power limit throttling it never comes even remotely close to its stated TDP of 65W. Instead it hangs around 45 if I remember correctly. Now, with it unlocked and during a stress test on all cores it reaches near to 65W. That's with 4 cores running full load at the advertised 3.4GHz. That seems to me to be the intended behavior. Why advertise it as a quad core 3.4GHz processor when single core loads always run at 4GHz (turbo) and quad core stuff runs at 2.9GHz. I know I'm relatively new at this but that just makes no sense at all.

I'm not actually looking to overclock or go outside the processor spec but to me it doesn't look like I am right now - frequencies are as advertised and so is TDP. I don't know where I could have read that 4 core operations max out at 2.9GHz. That's ridiculous for anyone who relies on multi-thread operation. To me it seems like Clevo limited this out of a (false?) sense of safety. Perhaps it's necessary to keep heat under control when the 980M is also being used but I will never do anything to tax mine.

 

You should be able to hit 3.7 with that processor. I have the same processor in a MSI barebones.

 

On all four cores at 100 percent load?

 

The max listed speed for the 6700 is 3.6Ghz and have a look at the oackage power over just the core tdp.

 

Where are you getting 3.6GHz? I don't mean to sound contrary but it's so confusing when everybody says something else and none of it is what the website of the manufacturer says. According to HWMon (on the previous page) package power never exceeds 45W during an AIDA64 stress test so I really don't see where that would be going out of spec.

I still feel what I encountered was an artificial limit by Clevo. I found a review of a Schenker U607 that seems to corroborate this - it has a 6700K but the review states that there is "marginal downclocking" during full load to 3.3GHz (from 4.0GHz for the K) in order to not exceed the adapter's 230W spec.
To me that says it's not an Intel CPU limit but a Clevo power limit. I happen to have gotten a 330W adapter with mine by the way, not to mention I'll never stress the GPU.

 

Get a K processor.. Non K 6700 is going to have behaviour like this... Intel literally cripple them..

If you read the thread than you'll see that I solved my original issue. I'm not looking to spend another 400 bucks for a new CPU at the moment.

 

Sooo... Still nobody with a suggestion on how to obtain an aftermarket BIOS for my P771-DM1-G? Or a better way to contact Prema? I'm not looking for a free ride, but there are no Prema Partners here in Holland and I had no idea I might need one (or even that Prema existed) until after I got this laptop.

 

PM Prema... I don't think a mod is out for it but should be soon.. Send a donation on the way too

 

I tried, two weeks ago, no reply

 

Also waiting on a lot of stuff from myself these days...

 

I would just like to follow up and close this topic by saying that Prema got back to me and we had a very fruitful exchange. Great service and a great and easy to use installation package. Thanks everyone!

I'll open a new thread asking for advice on BIOS tweaks.

 

Hi Sander, Also a guy from the Netherlands here with the same laptop. Can you tell me what you did to get the bios update?

 

Just what I said, Prema got back to me. I made a donation to him out of appreciation but only after he got back to me and I believe it's voluntary.
