[BIOS/vBIOS - MODS] Prema Mod™ & Stock

Recommended Posts

Woooop! Sent you a little donation :) Now to just post 5 times..

Hmm.. I've just downloaded, installed and got your modded bios working.. But I don't see any settings for changing the fan profile?

https://youtu.be/qHyYBm__WyI?t=52s

Is this an extra mod someone else has installed or?

He added a LOT of non-working and dangerous (read: bricking) stuff.

The FAN stuff he has there does nothing as FAN control is all in the EC not the BIOS.

Also use the Mod with latest Clevo HotKeyApp for better FAN behavior:

Hi Prema ! :D

Have you an approximate date for the release of BIOS modded for Clevo P7XXDM -G ?

The future... :D

Hi, Prema~Recently I found something wrong with my Clevo P370SM. It seems like a bug that if I press Fn+1 to turn on COOL FAN mode, then press them again for turning off it, but it turns out that I can only turn off COOL FAN mode of primary graphics card fan and CPU fan with ancillary graphics card fan still in COOL FAN mode.Unless I reboot my laptop, the COOL FAN mode of ancillary graphic card would be open all the time.

Could you please give me some advice?

Plus I use 970m SLI.

Thank you for attention!:look_down:

You could try things like reflashing the EC and cleaning the FAN/GPU contacts.

Thank you so much. It says P17SM-A

Now one more question: Has anyone here seen random thermal shutdown events on either a Sager NP8278 or a similar Sager system? I have had the CPU and the MB replaced just last week but this problem is still happening. Most often than not, It tends of happen when the system has been in sleep or hibernation for a set amount of time. I get a beeping error, the fans kick in to max and the 3 indicators on the LED panel start flashing together. Despite the fans running at max speed, the system shuts itself down after about 30 seconds. This is actually the reason I am here as I suspect that this may potentially have to do with the EC and the temperature or fan tables. In fact, when I just got into BIOS to check my MB version, the problem happened and the laptop shutdown. After the laptop is shut down, it's OK until it goes back into sleep after being turned back on. As opposed to shutting down, rebooting the laptop doesn't fix it. This actually has been happening for a long time and I noticed it occasionally happening when opening up a game for the first time. When the game is opened, the alarm kicks in. If you quickly close the game and get back to the Windows desktop with no other apps running, the alarm stops. At that point, you can restart the computer but when it restarts, trying to launch the game usually causes the same problem. Instead, if you simply do a shutdown, the problem is resolved (until laptop goes back into sleep).

After having gone through 2 MBs and 2 CPUs with this problem, I figure the problem is most likely BIOS related. Especially considering the fact that temps are not abnormal when the thermal shutdown process is in effect (all cores around 50C).

Prema, I would like to officially thank you as your BIOS appears to have solved my issue! I haven't gotten a single thermal alarm/shutdown since the BIOS flash. I think it was specifically the EC update that did the trick (and I used the cool fan option rather than silent - which I personally think is still relatively silent).

Now with all the new options available in BIOS, I wish there was a guide to tweak everything to optimal values. :)

Anyone know if the P650SG can do 3D vision out of the mini display port using an active adaptor to dual link dvi?

Hi, @Perma. I have a P770ZM, and I am using your wonderful BIOS. I recently installed a Samsung SM951 NVMe in the M2 slot with 4 PCIe lanes. I have seen many posts with sequential read benchmarks approaching 2000 MBs using AA SSD. However, I am only seeing around 1350. Is there a setting in the BIOS that I should tweak to improve the throughput?

Thanks much!

How do I make the P750ZM recognise the nvme drive in PciE x4 slot please? Plugged in the 950 Pro today but could not see it anywhere in BIOS. All SATA slots are showing blank even though the drive is plugged in (I'm certain it is the right slot). I'm using the latest PremaMod, all default settings right after flashing. Just plan to install fresh Windows. Thank you.

On my m5 pro it shows up as an off board controller in the UEFI/Bios. You should not see it in the SATA section as its a PCIx device so that part is ok. Make sure CSM is disabled in bios and windows 8/10 should be able to see the drive

Thank you Prema for your work.

I'm planning to update the bios in my Clevo W150ERQ and have two questions:

1. What is the difference between the "OV" and non "OV"? (W150ER_16_09_PM_v3_1920x1080_OV.rar or W150ER_16_09_PM_v3_1920x1080)

2. In the bios downloads above there is nothing in the README.txt file. It is just blank. Should there be instructions in there?

(I thought I posted this earlier but it didn't come through, sorry for the double post if it shows up.)

I'm getting ready to update the bios in my W150ERQ, in preparation for upgrading the CPU.

What is the difference between the "OV" and non-OV versions? Which should I install?

Also, when I download the Prema bios there is nothing in the README.txt file. It is just blank. So what are the instructions for flashing the bios W150ERQ? Thanks!

Just load setup defaults and it should be P'n'P...

1. OV = GPU overvolted

2. You probably used the wrong password to unpack the archive which results in all files to be zero bytes and empty

Thanks for your reply, @Prema. Sorry I misspelled your name in the last post. :)

I have played with a few different NVMe drivers: the Samsung drivers (version 1.4.6.7 and "rev10"), the default Microsoft Windows 10 driver, and the Intel drivers (versions 1.1.0.1004, and 1.3.0.1007). The performance with the Intel 1.3.0.1007 driver was horrendous - definitely geared only towards the Intel SSDs. The Intel 1.1.0.1004, Microsoft, and rev 10 Samsung drivers all had similar performance. However, the older 1.4.6.7 Samsung driver provided slightly better performance, so I am sticking with it for now.

While the SM951 NVMe performance appears mostly limited by the 4 lane version 2.0 PCIe, I also found that the CPU clock and memory timings affect the benchmarks, so I am also running with somewhat more aggressive settings. With the older Samsung NVMe driver and the tighter settings, my AA SSD sequential read benchmark increased from about 1350 MBs to about 1450 MBs.

As more and more NVMe SSDs are released, I will watch for different drivers and see if any increase my benchmarks. For now, I believe I am probably about maxed out.

Thanks again for your feedback, @Prema.

Hi Prema

Thanks for this great piece of work, seems like a lot of folks are having the same heat problems I'm having and I'm looking forward to giving the BIOS a go once I have been around the forums for a while. Once I use them and no doubt get good results I'll be sure to donate :)

Cheers

First off, thanks Prema for providing these bios!

I just flashed the OV bios for my Clevo W150ERQ and it's great. The computer has an i7-3630QM CPU and Nvidia GeForce GT 650M GPU. After flashing the bios, the CPU temp seems slightly higher at idle than before, (55C vs. 53C). The GPU seemed about the same (around 41C). I downloaded the Intel Extreme Tuning Utility and ran a benchmark. The test showed a maximum temp of 92C without any attempt at overclocking.

I would like some guidance regarding what temperature is safe and what is dangerous. What is the maximum temp I should avoid?

Is there anything else I need to do in the BIOS to play with GPU voltages and overclocking the CPU?

The increase in temperature comes from the Mod enabling CPU Turbo while the dGPU is used. Without the Mod the CPU Turbo switches off as soon as the dGPU switches on.

Temps in the early/mid 90s are still OK-ish for IV/SB CPUs...

I have noticed that every time I shut down the computer and completely power off, when I start the computer the bios flash screen always says something like "resuming from hibernation". Is this normal? On the other hand if I choose restart instead of shutdown I don't get the "resuming from hibernation" message.

Newer Windows versions default to standby instead of shutdown. You can set it to do a proper shutdown in Windows Power Options Advanced Tab. ;)

Hi Prema, I posted my notebook problem in notebookreview.com and got your reply to one of my posts. Since I haven’t seen you active in the P770ZM owners’ thread there for sometime, I am posting here:

I have a P770ZM with AMD 8970M GPU. The display brightness controls are not working. Control Center crashes everytime I open it. Even the Windows brightness controls are not available. I should also mention that the notebook BIOS doesn't detect the AMD card. The system and the GPU work fine though, except for the display brightness issue.

That card will work just fine except for screen brightness control (needs manual registry tinkering).

The BIOS won't show the proper name, but that's just cosmetically.

While trying to find a fix to the problem, I stumbled on this post. As you mentioned there that if the screen internal firmware can't interface with the EC then things like brightness control won’t work. I have an IPS panel (LP173WF4 SPD1) on my P770ZM. The current BIOS version of the system is 1.03.14 and EC version is 1.03.09 (latest). Even if I upgrade to the latest BIOS version 1.03.15, the EC version will remain unchanged and that won’t fix the problem.

Do you have any suggestion? Could you please provide an EC version update which can fix the brightness problem? Alternatively, it would also be a great help if you could tell what registry tweak needs to be done.

Hi just flashed prema bios mod and wanted ask about this cool and silent fan profiles. I thought silent fan profile would be better but it is not really silent. So there is a way to change this without flashing prema bios again ?

Thanks in advance.

You need to edit your registry manually for brightens control to work (google) as this system was never officially offered with AMD GPUs and has no direct support for them.

Thanks in advance.

The cool profile will spin up the FANs earlier and higher with high temps.

The silent profile will spin up the FANs later and not go as high.

If your average CPU/GPU temps are above the "silent" versions trigger temp then using the "cool" version may be more quiet as FANs don't spin up and shut off all the time and will instead run constantly on low.

Hi Prema !

Why Clevo BIOS 970M -G for P771ZM does not work on the P771DM-G?

They made a slight MXM board change...

Ok, thanks. I did try finding the registry tweaks and tried them too, none of them fixed the problem. The registry fix that was mentioned in most places is the below one:

"Go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000Next, go find:MD_EnableBrightnesslf2

KMD_EnableBrightnessInterface2

Set both to 0. Reboot."

MD_EnableBrightnesslf2 key was not there by default, so I added it myself. It should actually be KMD instead of MD. I have tried both, by the way.

I was quite hopeful that this would solve the problem, but unfortunately it didn't. If you have any suggestions, please let me know.

I bought a Avell Titanium G1746 V3X Fire that is a Clevo P671RG-G. As I saw on Prema Mod website, there is no P6XXRE firmwares for it, just P6XXSG and P6XXSE models.

Since mine uses a different chipset (HM170), different processor (Skylake 6820HK), I assume that the SG/SE versions will brick my device.

Considering so, is there any way I can help? I have software / hardware rev. engineering skills (not bottom to the BIOS level, but I already did driver level hacks).

      Hello Everyone,

      I am trying my Sager NP 9377 to get to work but to no avail. NO POST, NO DISPLAY.
      in short>> powering on laptop causes fans to run at full speed after 10(cpu only) + 10 (now both cpu+gpu) with Caps Lock + Num Lock + Scroll Lock LEDs blinking, continuous 1 second beep, repeats for one minute with 1 second in between, then laptop shuts down.

      IN DETAIL
      System Specs are i7 4810mq 8gb gtx 880m SLI variant (though my laptop has other GPU Slot empty so only singular 880m running) 120 Hz display.

      The Problem
      > if i take out the battery and plug in AC only, the power light comes on ORANGE
      if both battery is connected, then i have both power and battery light ORANGE
      and if only battery is connected then of course laptop is waiting for me to press the power button
      but in all 3 cases the following happens
      > Pressing the power button brings laptop to some signs of life, power LED turns green, both the CPU and GPU fans have a very quick jerk but does not spin., keyboard lights up with Blue Backlight (dont know if this is relevant or not), HDD activity light starts to blink showing HDD access maybe (even when hdd is removed)
      > Display remains blank (i dont even sense the display backlight being on)
      > HDD activity light sometimes goes off after only 1-2 seconds, sometimes shows rapid blinking/activity for 4-5 seconds
      > both fans remain off (i removed back cover to check this)
      > after about 10 seconds or so, the CPU fan spins up (speed is normal, just like when using the laptop in IDLE)
      > after 10 more seconds have passed, the CPU fan seems to be turning off for a split second then both the CPU and GPU fan turn on full speed with a lot of noise.
      > Caps Lock, Num Lock and Scroll Lock LEDs all blink together with single beep for about 1 second, repeats beep with 1 second in between.
      > goes on for about 1 minute then laptop shuts down.
      > forcing the fans to spin down using FN+1 key makes them spin back up to full speed after a split second (dont even know why i tried this one -_-)

      What I Have Tried So Far
      > EC and Bios Reset (take out battery, disconnect AC Adapter, disconnect CMOS Battery, Press Power Button for upto 30 seconds)
      > Change Ram and check all available slots
      change/remove HDD
      > Repaste CPU/GPU and clean out fans
      > Checked GPU...... Flashed the 880m in this Sager with MSI vBios and tested it in a MSI Gt70 2PC i have, gpu ran fine, tested with FurMark, AC Odessey, Ghost Recon Wildlands for over an hour (unfortunately the cooling in my MSI is not good enough it already runs hot, and this 880m causes thermal throttling as well as power limit throttling sometimes). Reflash 880m with original Clevo vBios and put back into the Sager, still no boot, same results as before.
      > Checked the CPU..........checked the 4810mq in the MSI GT 70 which worked fine, as well as tried the 4810mq from the MSI in the Sager, still no boot.
      > Suspected bad GPU fan connection......therefore forced both fans to full speed as soon as i press power button (using FN+1 Keys) and both fans turn on full speed, same results.
      > tried charging the battery to the max before turning on on battery only, same results.

      >>------- The laptop has had some random shutdowns in the past too during gaming but would turn back on fine after waiting for 10 mins or so, then i sold it to some guy who brought it back to me the next day saying that it just turned off during gaming and wont turn back on, i returned his money, did all the troubleshooting above to no avail. then i finally put it aside to wait until i get some other system in which i can test the CPU and GPU.
      Then one day i turned it on (after leaving it untouched for a couple months), same results as above, i decided to try once without battery and it Freakin Turned ON!!!, used it for a couple days without battery, played a few games (thermal throttling was observed here and there), but then this happened again and this time it seems permanent . And now i have not only repeated all the steps above but this time also checked the CPU and GPU in the MSI GT70 too. ------------<<


      Some Observations
      > touching the CPU heat pipes feels warm, but the GPU heat pipes are colder (GPU never even booted?). dont know if this is normal or not.
      > i replaced one of the capacitors near the CPU once, but i did use the laptop for quite a while after that without any issues.
      > my Idle temps were always below 40c for both CPU and GPU, so an overheat warning as soon as laptop is powered on seems unlikely (false overheat warning?, but GPU does not even seem to be detected/ booted as heat pipes remain cold to touch), also i repasted the CPU and GPU multiple times.
      > The guy who sold me the laptop told me that the power adapter was originally a Dell, and it was modified to use with this Sager by replacing the cable with a 4-Pin one from a Toshiba (same pinout as the Sager), but then again i have used this laptop for quite a while on the same adapter.
      > From day 1 of having this laptop, some keys on the keyboard (w, s, t, c and numpad 4) did not work 99% of the time. pressing really hard on any one of them sometimes made ALL of them work for a while. any thoughts on this issue?? (even if its unrelated).

      So what seems to be the issue here?
      GPU not detected ?, False temperature alert?, Bad fan?.
      Any help towards resolving this will be greatly appreciated.
      Thanks in advance .

      I recently purchased a replacement 980M (Clevo model) for my P770DM-G after the original died, however, after installing the card the laptop doesn't boot. I only get a black screen, and after a couple minutes the fans spin to max before shutting down, which is the same thing that happens when I try to boot it without any gpu at all. I've tried the reset procedure, unplugging, removing battery, and removing CMOS, to no avail. It does beep before shutting down (I counted 22 times exactly). Anyone have any insight as to what the problem is?

      Hello guys,
      I have a GT72VR 6RE with G-sync MSI Laptop. Sadly the GPU is partially dead (artefacts all over the screen, crashes, windows detecting a damaged hardware etc...).

      So I bought an other GTX1070 MXM on ebay, which was used in a Vortex G65 6RE before.
      Sadly, when I plug the new GPU in the laptop, the laptop screen stays completly off, but i can use the HDMI port. So i though that I would just have to flash the vbios to the one I was using on the GPU that died, but I couldn't because of a mismatch betwen the PCI Device ID.
      The new GPU ID is : 10DE 1BA1 - 1462 11AF and the previous GPU ID was :10DE 1BE1 - 1462 11AF
      Pretty close right? but the A1 and E1 variation are fcking everything up. I've read that 1BA1 is for non G-sync and 1BE1 is for G-sync. I've also read that the G-sync variation is not part of the card but is an external part no on the GPU board.

      So now I'm wondering what can I do : is there a way to force the vbios flash or to change the PCI ID ? I really need some help here. I'm no expert and I've try as much as I could. Maybe I need to do some vbios editing but I don't really know how to do it and what to do exactly to make this work.

      Thank you very much for your help guys
