Clevo P157EM ;)

Oh that's good news.

Apart from fixing your fan issues have you noticed any other benefits of upgrading to that BIOS/EC combo?

 

Not really.

However I am now pretty sure that the fan issue IS FIXED.

Also my CPU seems to be more stable at higher frequencies, it's like the P170 BIOS was using a bit too much voltage making it overheat at anything beyond ~3.1Ghz.

SO... NOW my quest will be to see if I can MOD the P150 BIOS, insert the XTU modules, possibly update stuff like the IME and the SATA PCI Option ROM, and perhaps the broadcom PXE rom too.

I wonder if I could use something like gPXE....

Anyone messed around with doing stuff like this?

 

Hrmm so according to Prema we will brick the machine if we put the P170 XTU modules into P150 bios. Sad Oh well, I am just going to leave it as-is now with the latest P150 files on it as it is working quite well .

 

Ok, I can not listen your crap. Fortunately, you damaged only ethernet port, and not burned all laptop like Mythlogic do. Please stop because tdididit die laughing, and I lose my partner.
BTW, I finally installed modified motherboard from P170EM (crossflashed to P150EM) to P150EM, and like my two P150EM crossflashed to P170EM, also works without issue.
Regards

 

What the hell is your problem dude? My Ethernet port being damaged has NOTHING to do with anything in this thread. Quit being a smart alec and treating me like a friggin newb who has no clue. I know what I am doing, I have been doing this sort of crap for a LONG time. Frankly I think your poor understanding of english has a lot to do with your negative posts regarding me. That's pretty sad really.




On another note: Fan issue is still present So it must have also had nothing to do with any of the BIOS flashes either.

 

You better watch your brick like a hawk extide you will be pushing it to its limits.

 

Blimey so maybe the more recent 170EM EC/BIOS releases will work on the 150EM just fine.

Do you have any idea what is causing your fan issue then?

 

I ran the latest P170EM bios just fine on my P150EM.

The only issue I had was that the graphics fan would not quite reach top speed until the graphics hit 90C, at which point the fan kicked into high gear but not before it throttled so reaching a happy steady state relied on less than maximum fan speed.

 

I understand what you're saying. You have a problem with listening other people.
I told you that your problem, if it exists, is not related to the topic.
Regards

 

My problem.... if it exists?

Are you implying that I am making up this whole thing? I know exactly when the "problem" started occurring, which was after I went from P170 bios 07 to P170 bios 10, and also updated to the respective P170 EC.

How does that make it not related to this thread? It's directly related.

I have now gone through many different BIOS and EC combos, both P170 and P150 ones, and have not been able to restore my GPU fan operation to normal. To this end I am still not exactly sure why I am having the problem.


I have some questions on your P150's running the P170 files, what frequencies are you able to get your CPU to run at, and what kind of temperatures are you seeing? When I had P170 files on my system I could not get the CPU to run (with all 8 threads loaded) at anything above 3.1Ghz, as it would go over 100C. Now that I am back on P150 files I can run all-thread-turbo (3.6Ghz) just fine, with all threads loaded. Why do you think that happens?

You say your system works fine but how much have you really tested and pushed?

 

Hello everyone.

First of all, sorry for my bad English and to be off the topic but i have not enough messages to send pm.

Bonnie_clyde, where did you find a white keyboard for you P150HM ?



Thanks

 

Hi,
It is a (GB) keyboard from Clevo W760.
P/N: 6-80-W7650-192-1 (Chicony Model: MP-08J46GB-4301)

 

Thanks ! I could be interested in buying one.

 

So, in-case anyone is wondering, I have finally figured out my GPU fan 'problem'. Honestly, it's a bit embarrassing, but the GPU fan has actually been working as designed the entire time. The later versions of the EC have the GPU fan entirely shut off when the GPU is not being used.

Now, I use throttlestop on my laptop. I had it configured to display CPU and GPU temps in the system tray. The action of polling the GPU once per second caused the GPU to essentially be on all the time, but yet the fan was not coming on because it wasn't on long enough to trigger the EC. This caused it to get very very hot over time. The fix? Turn off GPU temp monitoring in Throttlestop. The fan operation hasn't changed, but the GPU now actually sleeps properly, and stays cold. I didn't catch this until I was reading a post by the guy who made throttlestop about how polling the temp would cause the GPU to wake up and it hit me.

So, now the laptop is nice and quiet and the GPU fan works as it is supposed to.

Only problem is my ethernet port. It seems like the solder joint between the jack and the mobo is the problem, as I was able to get it to work sometimes by wiggling the cable. At first I thought I was dealing with poorly crimped ethernet cables, but alas it was the jack, not the cables. This is pretty sad, because I am VERY careful with this machine and it is in otherwise perfect physical condition.

I am still on the P150 BIOS/EC at the moment.

Now that I have sorted out the GPU fan 'issue' I may go back to the P170 files, but I am not sure. I need to do some actual scientific testing to confirm this, but it seems the P170 files made the CPU run hotter (higher voltage??) and so I was actually getting better performance at stock with the 3920xm on the P150 files vs the P170 files as the CPU would overheat at speeds lower than the stock boost capabilities.

It's not like this computer is slow, so I have just been satisfied with leaving it as it for now. I really want them to come out with next gen hard drives so I can get a 2TB 2.5" drive that will fit in here. I know there is the 15mm WD one, but I don't think that baby will fit in the cdrom bay.

 

Different mobo understanding makes weird correspondence for the CPU -did you run XTU and check the stats for your 3920XM when you had the 170 bios?

moving on, they wont WD will probably make it a little to big.... and it's not like there's a lot of space to deal with... sad I know

 

You can run a HW monitoring program to see if the actual voltage is being reported higher? Did you set the fans to max on both to make sure it was not fan profile differences?

 

How can I set fans to max? fn + 1 doesn't work on my machine. Also, not I haven't actually monitored voltage as I really noticed it more-so when I went BACK to the P150 files after running the P170 stuff. If I ever put the P170 files back on I will do some measurements and tests.

 

There was a answer somewhere in the P150EM thread, the official one, where I don't remember if it was the BIOS or EC (the newest one) fixed and enabled the FN + 1 in the EM machines again as in the HM machines

 

I believe it's the EC that has the control registered in it, but using a sager EC with a clevo stock bios may cause issues.

 

I am pretty sure I am running Sager BIOS and EC at the moment. So, just using the latest Sager stuff should get fn + 1 to work? I will email Sager, and ask for the latest files then.

 

extide,

Whether you say in the end that you were wrong, whether you will continue to look for problems?
Some of the results may be weaker due to board ID resistor mismatch. Since the EC / BIOS can set some parameters for safe rather than optimal. But certainly nothing will be warmed more.

 

So, you think that there may be some resistors different between the P170 and P150 boards, regarding power supply to the cpu?

Yeah, I was wrong about the fan issue, but the thing is the behaviour did change between my laptop as it was shipped, and then the later version files. My original BIOS/EC caused the fan to stay on all the time if needed, which meant that the GPU would not overheat when I was monitoring the temperature with ThrottleStop. As this was how it worked initially, I took it as to how it was supposed to work. In the later versions they changed the fan behavior, so that the GPU fan would turn off entirely when the GPU was sleeping. IMO Clevo/Sager have overlooked a potential bug, which can allow the GPU to overheat in that certain scenario. Because they modified fan behavior in the later version files, I had to modify the way I used ThrottleStop as well. So, the fan behavior is different than what it orginally was when I got my laptop, but I now have it working properly in the new way.


I'm not afraid of admitting I was wrong about something, infact I don't even really care. Being right or wrong has no significance, only the truth is useful.

 

You'll find it close to the KBC / EC chip.

 

Very handy.... Iam assuming they are tiny SMD resistors, right? Pain in the butt...

I may end up needing to get anew motherboard for my system to fix the ports.. If that is the case then I can use the old one to mess around with some mods and crap...

 

IS there anyway anyone could modify the p150em bios to stop the cpu from not turboing when the dGPU is on?

 

No since that is not something tge p150em does .

 

Are you sure the p170em does not give the CPU mroe volts or anything cause my CPU fan seems to be on a lot more often.

 

yeah some people have been saying that. nit sure though. can't confirm sorry, staying on my stock bios for now

That's because it has a different fan profile

 

Hey guys

Does this also work with P170EM 1.02.12 EC and 1.02.17 BIOS on the P150EM?

 

Just use the latest EC (flash it first if upgrade) and Bios (flash it first if downgrade) for P170EM.

 

Thanks!

I'll try it when my 3720QM ES QBC1 (Open multiplier) arrives. If I can't OC, maybe the P170EM BIOS+EC is able to.

 

You wilo need it yes.

 

Couldn't wait - worked like a charm!

 

I would think twice about that early revision ES TBH, it's unlikely to be any better than a retail sample at +400mhz and is more likely to have bugs.

 

I already ordered it. I think this is an experience I need to do on my own. I read about mixed experiences. So i can't make a real decision about that. I will have an experience - not knowing if it's gonna be a good one or a bad one. Just like with other replacement parts. OEM is also not guaranteed full-functional.

 

OEM chips should be fully functional, they are chips intended for end users.

 

I'm still really hesitant about flashing. Did you flash both EC and bios? Also do you experience any additional temoerature and fan noise?

You have to flash both without restarting so you either edit the batch file or put in the command manually leaving out the restart switch.

 

ok so what line would it be in the batch file? is it pretty clear? also there are 2 batch files one for ec and one for bios

Sent from my Nexus 4 using Tapatalk 2

 

Yes you would need to edit both as they both contain the shutdown command, edit it out, and when in dos flash both before restarting.

 

ok one last question, ive donloaded the files and in the readme it says I have to run MEset.exe between the EC and bios flash (with rebooting) is this necessary if I have already done this when upgrading the regular bios, because I am now flashing the exact same bios version I have already got, only difference is that its the p170em one...

edit: ok the EC bat file reads this:

AFUDOS ECP170EM.12 /e /shutdown /x

how much do I have to delete?
also the bios script looks complicated, can I just leave it as is and let the machine reboot instead of taking the code out and rebooting manually? sorry complete noob here....

 

just delete the "/shutdown" part

 

ok and keep the /e and /x?

Sent from my Nexus 4 using Tapatalk 2

 

yep

10chars

 

ok and also in the bios bat or can i leave that one, as the machine has to be restarted anyway?

Sent from my Nexus 4 using Tapatalk 2

 

IIRC the MEset.exe has to be run first in order to update the IME firmware. after that, flash the EC first, followed by the BIOS without a reboot in between. but im open to be corrected, if anyone knows better

u could always contact Prema about this, hes the resident Bios/EC wizard here in the clevo section. he will know for sure

 

I Flashed all (EC, BIOS) normally, with reboot. Both mobo (P150EM, P170EM) is the same.

 

Yes it can be fine but if you get the wrong combination of bios and EC you can brick it.

 

Is anyone else finding that if you install the latest P170em EC and Bios update on the P150Em that the machine does not shut off after Windows 8 shuts down?

Thanks.

Revision... forget that... works fine with Clevo Official BIOS
