CPUZ shows 0,589 V when idle (800MHz) with -83,9844mV undervolt and 0,671V in idle (800 MHz) without any undervolt. So my VID is slightly better. Thanks for the explanations.

 

Also the VID only tells the voltage for a certain frequency, the curve at other parts may be different as other bottlenecks kick in.

 

I would like to set up some custom refresh rates (47.952Hz and 48Hz) for watching movies. However, when I try to add the custom resolution of 1920x1080 at those refresh rates in the Intel Graphics control panel, I get an error that the bandwidth was exceeded, which does not make sense as the bandwidth is less than if the display was running at 60Hz. How do I force adding a display mode?

 

Have you tried doing so in Nvidia Control Panel, this thread may help out http://forum.notebookreview.com/sager-clevo/660283-you-guys-know-you-can-overclock-lcd.html

 

makes sense, mine crashes on .587mV with a -80mV undervolt on light 2.4Ghz loading.

 

Ok so the voltage of the lowest state can easiely be checked when idle - and the highest state with a Prime or XTU Stress Test running.
Is there any way to check the States in between?

And i need your help i would like to set my undervolt offset permanent - in the Prema Bios Settings (under CPU settings - must be the last three entrys). Which values should i set to get an -83,9mV (VID offset voltage)? If its possible to be set it in Bios with those mentioned settings....

 

I managed to get Audio working with Voodoo (V286 Mavericks). At first it doesn't seem to work but that's because the default output is via HDMI. You can use the Voodoo control panel app to change the output to the speakers.
Wireless is also working now, but I had to change the original internal card (Intel 7260) to a Broadcom BCM4352 (ordered via Ebay).
Batterry indicator works using the ACPIBatteryManager.kext from RehabMan (2014-0207).

Outstanding issues:
- Sleep not working
- QE / dispay driver not correct

The display is in QHD, but very slow in updating. I removed all the graphics kexts, so i'm still searching for clues to use the display with correct drivers. I did found this:
Dell XPS 15 (9530) - Intel HD 4600 Graphics on QHD+ built-in display - Need some help

Seems much simpler than the suggested thread, but a required pre-requisite is setting the Pre-Allocated DVMT size to 128M. This option does not exist in Prema mod (as mentioned earlier). Any workaround for this?

So the laptop is almost fully working except for one of the most important things: Quartz enabled display. Watching video fullscreen is now impossible, like 30 frames per hour.

Cheers!

 

XTU is probably the safest and best, it is persistent across reboots and doesn't actually reset unless your laptop has crashed in some way. I think the BIOS settings are the IOUT commands but I don't see a difference when I used it.

 

No workaround. The option is practically a requirement. As for sound, yes, VoodooHDA works, but using a patched, native AppleHDA is always better.

In fact, I also experience graphics artifacts, even if I have a 1080p display. I've already asked Prema to look into this, and he says he will do so.

As for sleep, you need your display drivers to work properly.

PM me your mail IDs!

 

Thanks for the quick reply, Prema. You're the best. I've sent in a PM.

 

Thanks a lot Prema! Some help is definatelly welcome . I sent you my mail address.

 

Hey guys I am having this issue:

When I boot up the text is extremely blurry, If i connect my monitor its still blurry, then I restart the computer while still connected to the computer and every thing is fixed.

It might be some kind of profile for the computer built screen? I can notice that the whole windows UI is kind of bigger and weirder, maybe its the resolution?(I checked the windows and intel driver but its correct)

I do have Prema, and the 1080P screen

 

Is it blurry to a point where it looks like a lower resolution? Are both your external and built in set to the same resolution, and are they set at clone or extend.

 

Prema, I think everyone acknowledges you're the most awesome dude. I wholeheartedly agree with that opinion! You just made my day; Full retina QHD+ Quartz in OSX on the W230SS!!! You're the best!

Info: After setting DVMT to 128 I only needed to patch /System/Library/Frameworks/IOKit.Framework/Versions/A/IOKit. Since I installed the combo patch for which the correct patch is not included in the pixelclock fix script yet I used the following manual commands:

Code:

sudo perl -i.bak -pe '$before = qr"\x0F\x85\x9D\x03\x00\x00"s;s/$before/\xE9\x84\x03\x00\x00\x90/g' /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit
sudo touch /System/Library/Extensions
sudo codesign -f -s - /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit

To use codesign you need to have the XCode extensions installed so make sure to have internet. Before doing so I moved /S/L/E/ AppleIntelHD*, AppleIntelSNB* and AppleIntelFramebuffer temporarily to another place in order to boot graphically. Then I executed the patch, restored the kexts from /S/L/E/ to their original location and rebooted.
Then it worked.

Oh, and don't forget to modify the config.plist in /EFI/CLOVER. As boot argument you'll need nv_disable=1 to skip loading NVidia drivers.

You'll also need this kext patch in the config.plist:

HTML:

<dict>
    <key>Comment</key>
    <string>Enable 128MB for Azul framebuffer 0x0a2e0008</string>

    <string>AppleIntelFramebufferAzul</string>
    <key>Replace</key>

And this:

    <false/>
</dict>
<key>InjectEDID</key>
<false/>
<key>ig-platform-id</key>
<string>0x0a2e0008</string>

Sleep is still not working, but that'll probably have to do with somethin' else. I'll follow SRSR333's pointers to see what's next

Thanks a lot!!! And hopefully others will be able to use this information to turn their own Clevo's in hackintoshes. Triple boot, Win 8.1, Hackintosch and Linux . Best of three worlds!

B.t.w. did I tell you that the screen is amazing? I think it even looks better than the real deal (on OSX).

:hi2:

Update:
Sometimes small corruptions are visible, selected menuitems appear corrupted with purple and green lines and sometimes icons are corrupted. Small issue, not very annoying.

 

He is an awesome dude, I hope people are still sending him at least some beer money as they grab his bios files etc.

 

The stupid s have recieved my laptop (yeah, the one that I should have had on my doormat 3 weeks ago. Working.), so I'll see what they can make of it, and how long it's gonna take. I fear the worst, if they have to send it back to the manufacturer :/

 

Because this laptop uses Optimus, there are no display options available in the Nvidia control panel. All the display settings are in the Intel control panel, and like I described earlier, they don't work.

 

Nvidia control panel still lists display options. Hutsady and I both have Optimus enabled systems and have everything listed in there. In the past when this has been reported by people a driver reinstall (clean install) would fix that issue right up.

 

It look strange and kind of blurry, might look like a lower res, i use it in a way that only one of them is active at a time, and they are different, I checked it on each and its set ok, but still if I go back to the computer's screen it triggers the issue,

 

Hmm, where did you get the drivers from? I did a clean install of 8.1. Windows automatically installed the Intel GPU drivers, and I downloaded and installed the 860M drivers from Nvidia's website first thing. About as clean of an install as you can get.

 

I would recommend installing the ones provided by Sager if you're having issues accessing those options. When they're installed correctly you can acess Nvidia control panel settings. Once you're able to fix the issue then you can try doing incremental updates to different versions and hope that it sticks through to the current version. If it doesn't you'll know where it stopped working and just use those for the time being until a new version releases which will hopefully address that issue.

 

Could you please post a Screenshot of the available settings?

 

Here ya go!

 

Have you tried ThrottleStop to limit the multiplier and then apply a load to the CPU? That is the only way I could think of to view voltages at different multi's.

To check stability of an undervolt, I typically load and close misc programs repeatedly as a first step. I usually get crashes quickly that way with excessive undervolting. I am sure there are better ways to test, but this is a quick and dirty first test. Also quickly running and stopping the intel XTU CPU stress test repeatedly does the same thing for me. I started getting crashes much past -90mV so I stopped there, and have not experienced any crashes since.

Edit - no clue how to get it to stick in bios. I have not explored it.

 

This is very helpful to me. All I have is 3D settings in my NV control panel.

 

Yeah, used to be an issue we saw pop up pretty commonly for some reason. For some reason the installation gets messed up and only has minimal things listed, takes a reinstall to fix.

 

Could be I am running 327.23 drivers with a modded inf file on my 880M.

 

Well shame on you if that's the case

 

I'm a bit stumped on it. Have you tried manually changing sound options within the control panel while using WiDi or HDMI meaning changing the default audio out to go from HDMI out to something else then back to HDMI whether you're using HDMI or conversely while using WiDi? I haven't tried WiDi myself so I honestly don't have any frame of reference to better assist you but I still get the impression that it has to do with audio.

 

When installing the Prema bios mod, I got an error message during the second step. It was when the Intel firmware update utility was running, and all I remember was a message about the CPU not having permission to write to something. However, the computer still boots fine. Is this bad? Do I need to reinstall?

 

I tried it again. Clean install of Windows, and I installed the drivers from the CD this time (332.66), and still nothing.

 

I have this problem too on XMG P304

 

Ok guys, just got Skyrim from Steam (there's a 66% sale going on now). I get 60 FPS almost all the time on ultra settings, with no mods. I want to install some mods with eye candy; I've installed everything in this list and now I get single-digit FPS:

http://www.gamefront.com/10-graphical-mods-that-overhaul-skyrims-visuals/

I haven't OCed my GPU.

Secondly, my screen colour calibration resets every time I tax the Nvidia GPU, i.e. when I launch a game. It then goes back to what I set it after I quit. Any ideas?

 

Then you didn't do step1 or didn't connect the AC Power for the flash resulting in the ME firmware not being updated.
(please follow the readme instructions to the dot).

 

Hi Prema, Welcome back

Anyways, would you happen to know how the IOUT power functions in the BIOS worked? I assume they are for undervolt/overvolting but the settings don't seem to alter the VID at all.

 

Wow im impressed, i could never get all settings to show up in an optimus setup. I had a P170EM with 680M MXM card before and now the P304. Could you tell us some more Details:
1. On which Clevo model the Screenshot was made on.
2. Which NVIDIA dGPU (MXM or soldered) was used
3. the exact Intel iGPU driver Revision
4. the exact NVIDIA driver Revision
5. OS Version 7/8/8.1 - 32/64 Bit / UEFI or non UEFI installation

I would like to find out why all those settings are missing in my Installation.
Helpful would also be to know the exact order in which you have installed the drivers.

During my research i only found this statement from NVIDIA in the Geforce Forum:
https://forums.geforce.com/default/...n-nvidia-control-panel-/post/4195917/#4195917

Maybe you could post a Screenshot of the mentioned PhysX tab too.

Thanks in advaced

 

I'd like to know what model as well as in optimus setups it's true those menus won't appear normally. I've got them back using a modded inf set before but the customise button won't work.

 

Folks, I got an idea.
Maybe it would be good to add a link to all the reviews made by the people here to the TS, so that people thinking of buying this model have a lot of info and opinions condensed in one post at the start.
Maybe something to consider?

 

Just an FYI - flashing from Modded Prema Bios back to stock Sager bios works fine. I got the bios files directly from Sager.

 

I did step1, but when it rebooted, I accidentally allowed it to boot into Windows once, before I got it to boot from the flash drive again for step2. Would that be the cause of my problem? Since my computer boots up fine, is it worth reinstalling the mod now?

 

Hi guys,

I'm attempting to install OSX now. I want to ask, after installation is it safe to revert the BIOS options (UEFI boot -> Windows 8.1, dGPU -> enable, etc) to boot both OSes?

Thanks!

 

It's perfectly safe, but you won't be able to boot OS X with the dGPU left on. You will have to make a DSDT edit to make sure your computer doesn't draw power for the dGPU while using OS X. As a matter of fact, I only switch on my dGPU if I want to game. My OS X install is strictly for fooling around and for iOS development, which doesn't nearly need the graphics power of the GTX 860M. There are no games in my OS X install. I recommend you use the BIOS switch to deal with this rather than wasting time on a DSDT edit (it's easier as well).

And make sure your CFG Lock in CPU Configuration is set to Disabled, or else you will need to patch your kernel, which also wastes time. As for me, my UEFI settings were always set to Windows 8, as I use the Compatibility Support Module for OS X (I use Chimera as my bootloader because it's far easier to set up and maintain as compared to Clover).

 

Thanks for your answer! I'm pretty sure I won't revert the CFG Lock under CPU Configuration, I believe it doesn't do anything to break Windows.

What do you mean by "Compatibility Support Module" for OS X, however? A Google search didn't yield anything meaningful :X Did you install OS X while keeping UEFI settings set to Windows 8?

And yeah, I'm paying the price for choosing Clover now, haha. Can't seem to boot with Clover. But I'll figure that out

 

Yes, I did, but because I used Chimera.

Under the Boot tab in the BIOS, near the bottom, I believe there's an option called 'CSM Setting', or something like that. Inside, there's another setting, something along the lines of 'Enable CSM'. What this does is to allow legacy, BIOS-based bootloaders to load in a UEFI environment. Chimera/Chameleon are BIOS-based boot loaders; Clover is UEFI. if you're using Clover, you might as well disable it.

I suggest you use Chimera/Chameleon, as I feel Clover offers no real improvement over the former, but is in fact worse off because of its complexity. Some members of the hackintosh community may feel otherwise; but my motto is 'don't fix what's not broken', so I've got no intention to change if it works fine for me.

 

Alright, thanks for the advice! I'll try again when I'm free.

Just curious though, regarding the vents on the bottom of the machine. I have 3 vents that are covered up with a black sticker and suspect that it might be the cause of a warmer-than-usual palm rest on the right. (it's uncomfortably warm even while idling). Do any of you have the same black stickers covering the vents? It seems counter-intuitive to me to block vents with stickers on a performance machine ><

 

Edited.....

 

Yes they are there to help direct airflow over the internals.

 

So whats the general consensus on this machine? Buy or not? Once I get some feedback on that, I have to decide where to buy from!

 

can someone kindly provide the link to download the original BIOS from Sager/ Clevo/ Eurocom?
