1038 and 2505 are stock speeds. You're not underclocked.

Actually if you are using Windows in UEFI mode it prevents these settings from being permanently written to BIOS.

You need to install Windows in Legacy mode in order for XTU changes to be 'permanently' in BIOS.

Good to know that. I'm not ready to reinstall windows however so I'll just live with it.

That worked. Thank you!

Yes, but I have no idea how to change the at boot values.

Save opens a profile save dialog box where I can save the current settings into a profile file: (and I cannot override default)

More info: So anything I can directly set in PremaMod BIOS does persist across reboots. But the outlined settings in yellow have to be applied on every boot since I cannot set them in BIOS.

It only works with the stock bios/ec combo that you can find here or on my blog.

Can I flash the stock EC and keep your Prema Mod BIOS?

1. You are not only starting XTU, but actually applying the setting, right?

Are you sure you are doing a full shutdown? Windows 8+ defaults to standby or deep sleep. You can change that in Windows Power Settings under the Advance tab. (You can set multiplier also directly in BIOS btw, no need for XTU for that)

I'm using windows 7 and I tried both - start menu shutdown and command line "shutdown -s -t 0" If I do the multiplier directly in BIOS then yes it does work, however I also undervolt the CPU (by -75mV) in XTU and there are no settings for that in the BIOS so I would prefer that XTU settings would persist.

2. I misunderstood your problem...that sounds like Clevo HotKeyApp preventing the FANs from working. Uninstall it, reboot and see if they spin properly.

Then install it fresh without using custom FAN profiles.

Uninstalling HotKey fixed the issue. Thank you!

1. XTU writes directly to the BIOS. The settings are written after the first full shutdown. If they are deemed stable they will stick during the next boot.

Once that is complete you can even uninstall XTU and they will remain in BIOS until a BIOS reset or load of defaults.

OK, I must be doing something wrong:

• I start CPU-Z it shows max multiplier at 36
  
• I start XTU, CPU-Z now shows multiplier at 38 same as in XTU
  
• I exit XTU. CPU-Z still shows 38
  
• I do a full shutdown of the laptop
  
• I turn the laptop on and start CPU-Z once it boots. CPU-Z still shows multiplier at 36 until I start XTU again.
  

2. Use the BIOS Mod to set "Advanced" > "Switchable Graphics" > "PX 5.0 Mode" to "BACO" and the FANs will spin properly according to dGPU temperature even after it enters lowest power state.

(Also use ClevoHotKeyApp to set the system to "Entertainment" mode when full power is not needed in order to keep the system cooler)

Unfortunately this did not work for me. I ran Firestrike benchmark after this BIOS change and it still crashed once GPU temp reached 96°C. GPU fans were on but stayed at low during the entire time.

Any ideas?

Thank you!

Just flash the latest EC by using my stock version and ONLY typing 'x' and hitting 'enter'.

Hi Prema,

Sorry, when you say "my stock version" do you mean the version you provide as part of your Prema Mod package or a generic stock version from this forum?

Thank you!

On P6 you will have to use Intel XTU for voltage adjustments, but using the Mod will give you more options in XTU to do so.

Thank you. Two additional q's:

1) is there a way to apply XTU settings on every boot automatically?

2) After vBIOS upgrade while using 3d apps the GPU fans will often get stuck at a low level and the GPU will overheat causing either a driver or an OS crash. Right after reboot when the GPU drivers finish loading the fans then kick into high gear. Any ideas on how to fix/prevent this?

Thanks!

In the P650SG/NP8652 Prema Mod BIOS is there a way to adjust CPU core and cache voltages? I'm looking for a way to undervolt both as my CPU is running very hot.

Hi,

I've installed the latest Prema Mod BIOS for my laptop. However now the fans spin up rather late and without any overclocking my CPU runs into thermal throttling at 96°C until the fans kick in at full speed under any sort of CPU benchmark. Is there a way to tell the fans to come up sooner and/or a generic way of increasing thermal efficiency of the heatsink? Would changing the paste to ic diamond help?

Thanks!
