*** Official Sager NP9175 / Clevo P775TM Owner's Lounge! ***

That didn't work for me. All I got out of it was a periodic popping noise coming from the speakers which I couldn't solve, thank god I took a Rollback Rx snapshot and could revert to my original drivers. Anyone else have any ideas? This is my third laptop from Sager and the first time I've needed tech support from them and they've been no help at all, pretty disappointed. @Meaker@Sager?

 

I'm getting really annoyed by this random cpu down clocking issue. This mostly happens when I start BF5. CPU throttle to 28x(some time to 8x) . Once it's gone down, cpu will downclock to 28x until restart.

I can see there are other members with the same issue. This seems like a power delivery problem. When applications like BF5 start, they will activate both GPU and CPU simultaneously. That mean sudden spike in power requirements and EC/BIOS failed to provide. cpu throttle due to lack of power.

Have you checked the thermal pad contact on the CPU VRMs?

 

Have you reached out to your reseller as well? It should be ok so something is off.

 

Been 3 weeks since I've messaged my reseller and I've only gotten 2 responses. Really sucks to wait all this time when I'm sure it could've been resolved quicker.

 

Did you try calling?

 

They're in portugal so that's not really an option.

 

It cant be thermal pads as I changed them last week to Gelid GP extreme. I actually repasted last friday and I can clearly see markings on pads which suggest they are properly contacting VRMs.

I had this issue even with my original pads. I have standard bios with P1 set to 65W and P2 81.25W. I can run P95 small FFT without throttling to 28x for hours. Or CPU-Z avx stress test along with fire strike ultra for hours without throttling.

I mainly notice this issue with BF5. But last night game worked flawlessly. Initially thought its CCC 2.0 so uninstalled.

From reading the posts, and looking at your specs. I think you're hitting power limit.
BF5 is taxing and also uses AVX instructions making it draw plenty of juice.

So I would say increase the PL1 (65w) and PL2( 81.25w) to something more realistic as you have a 9700k (95w tdp stock)

 

Might be vacation and low staff during summer. How much does a replacement fan cost?

 

I'll check tonight but I highly doubt it. Because game worked fine couple of times without any issue. If I'm hitting the power limit then p95 small fft need to do the same (when stress with P95, clock speed vary between 36x to 34x). This is just simply drop to 28x or sometimes to 25x or even to 8x. And then i need restart to get back to correct values.

Anyway my CPU VR current limit setting is 600 so I'm thinking about increasing this value.

VR 600 is 150 amps.

 

It says 1/8 so it should be 75amps

If I remember correctly Prema mentioned that it's 1/4 and bios description is for old firmware and is not correct.

edit: here

 

Cheers. Good to know.

Np. Hope you're able to solve it.

 

Not a 775 owner, but curious, what is the roughly "standard" CPU VR value for no throttling? Does it depend on CPU (9700k / 9900k)?

 

Well. I think I tried everything. No luck. BF5 worked without throttling and then I restarted the system. Boom .. back to square one.. cpu throttled when I started the game. Basically TDP going down to 25w and maintaining that until restart. I really believe this is EC/BIOS issue.

I'll probably do a Win10 reinstall tomorrow and see if it's working. If not I'm going to send this useless fkr back for refund.

I'll post hwinfo screenshot tomorrow.

The default on my p870tm1 is 720 for the 9900k

 

At some point i had same issue. Though in Witcher 3. Out of nothing my fps dropped down to 20-30. I checked everything and it was due to CPU hanging at 2.4ghz instead of 4.5 ghz (back in days with i7 7700k).

In my case it was XTU that caused problem. Windows reinstall did fix it. Never since than i used broken XTU and sticking with Throttle stop.

 

I remember after uninstalling XTU it still left a running service, which makes no sense.

 

Yeah true that. I disabled that service using "autoruns" utility. Very handy utility for any windows system.

It's a handy little tool.

 

Ok I found the issue about throttling. CPU hit power limit and immediately down clock. If I set PL1 to 65W its downclock to 25x-28x and if I set PL1 to 120W its downclock to 34x-36x

According to hwinfo max wattage CPU used during BF5 is 76W so I'm well below the 120W limit i set in the bios.btw CPU 8core boost fixed to 42x with -100v under volt.

I'm thinking about either set PL1 to ridiculously high 190W
. because due to multipliers is set to 42x, it's never going to reach that limit. Or increase VR current limit from default 600 to 700.

When I set pL1 to 120w and fire up cinebench 20 multi thread benchmark (loop), CPU maintain 42x multiplier as set by bios and consume 82W. No downclock issue.

@Meaker@Sager any advice much appreciated?

Tested Aida64 stress test (only check the stress FPU box) for Cpu and Heaven for Gpu and run it simultaneous? As wll check max power consumption from the wall with a kill-a-watt and see when it cut the power.

 

I'll do that tonight. Btw do you think my power supply playin up?

Anyway this throttling issue not always happening, when I play BF5 system maintain 42x even when I set PL1 65W. Then sometimes it simply drops to 25x when instant the application and need a restart to get it back.

Sent from my SM-G970F using Tapatalk

 

Delta 330w psu should be good for 400w from the wall. A cheap kill-a-watt to measure power consumption from the wall is a good idea. Not sure if you have @Prema mod firmware. I expect standard Clevo firmware have a power cap on max power consumption.

Run mentioned tests over a longer period. Follow max Cpu temp because it will run hot.

 

Ok will do tonight. I have a Delta adapter if I'm not mistaken.

My temps when I run BF5 1hr multiplayer (when cpu not throttling and maintaining 42x) is CPU 83(max) GPU 74C (Ambient 22C and max fan).

Ok I definitely think this is EC/BIOS bug. So I hooked it to a Kill A Watt meter and decide to take some power measurements.

First I set PL1 120W/PL2 150W/ VR current 600

8 core boost set to 42x

Booted to BF5 and initially watt meter displayed 290W then after few seconds it dropped to 260W. Played 2x mp maps and checked hwinfo. As expected power limit exceeded and throttled to 35x

Then I set PL1 190W/ PL2 disabled(so it's in cpu default mode)/ VR current 600

8 core boost set to 42x

Booted to BF5 and watt meter displayed 290W and played 2 maps. No drop in wattage. Then checked hwinfo and surprise... no throttle!!! So then I shut down system and did the same again. Same results. No throttle. Repeated again same result.

@Papusan

I did AIDA64 FPU Stess test(8 core multiplier 42x) along with Heaven benchmark(1080p res extreme setting)

Total run time 16min. Temp slowly increased to CPU 93C and GPU 74C. I stopped the test when CPU hit the 93C.

No CPU/GPU throttling and cpu maintained 42x all core multiplier. CPU consumed around 93W during test. No power limit exceeded massage on Hwinfo.

Maximum power consumption from wall plug is 314W according meter.

Anyway BF5 again manage to exceed the cpu power limit and throttle . However since i increase the PL1 to 190W, CPU only throttle to 41x multiplier from 42x. Maximum cpu power consumption is 68W during that gaming session.

Turbo does work on some very quick spiky consumption levels.

 

Prema contacted me today and I got Prema BIOS along with GPU (boost) BIOS update as well. So all good now and finally no issues so far.

Glad to hear bro Prema sorted you out His work is the only thing that makes these laptops fun!

 

hmm, wait a minute, what is "GPU (boost) BIOS update"?

 

Perhaps vbios?

 

Yeah I meant vbios. I think it got more relaxed power limits

Sent from my SM-G970F using Tapatalk

 

That'll be the one yes let's it boost more freely.

 

It's working fine. Problem is temperature. Extra boost make it really toasty. 87C when i play BF5 (75C before) and that extra 12c also increase cpu temp along with it. For the first time CPU hit 96C (before 83-85C with 42x all core multiplier)

Interesting. So there is an RTX vBIOS with increased power limit?

 

Not originally.. Only mod I think so.

I didn’t think it was possible to mod RTX vBIOS with a higher power limit either, although I know crossflashing is a thing.

 

Unless it is just an optimised curve built in. Not something I have played around with.

 

It's a modified bios. Power limit increased to 200w. I start playing with voltage curve to find sweet spot. Otherwise problem is due to shared heatsink gpu increase cpu temps.
That extra 40W push GPU to 87C during BF.

Anyway anyone got unmodified Clevo RTX2080 bios? I forgot to ask Prema to backup mine before flash and I need default bios incase I have to rma this unit. My retailer not allow modified bios and void the warranty if they find out any bios modifications.

Old way Flash back original firmware won’t work if your machine can’t boot or starts and you need RMA for repairs Only a hardware flasher will works.

 

Yep I know. Even for not so serious things like dead pixel warranty will be void if they knew I flashed. That's why I need the original vbios. In case I have to I'll flesh it.

I RMA'ed my old 775DM twice for dead pixels and once for noisy rattling fan. First thing they asked is if I'm on modified bios.

@Papusan what voltage setting indeed to undervolte if I need little cooler cpu other than IA core voltage.

Sent from my SM-G970F using Tapatalk

 

Core and Cashe. There ain't much other voltage settings that help cpu run cooler (at least for LGA machine who lack iGPU). A good start is around -100mv. But no cpu is equal. You need to test what fits your processor

 

Cinebench R15 is great for testing voltage/stability, instead of things like aida64/prime95 imo.
Undervolt ->test ->pass/fail ->less voltage/more voltage -> test again

 

Woah, wait, Prema unlocked RTX vbios? Guess i'll annoy him once more then...
