RE: Venue 11 pro i5-4300y Throttling

Jump to solution

I can't speak for the method he's utilizing, but if you're able to use XTU, there's no need to use the baredit program at all.   Just do the BIOS mods, start up XTU and make whatever changes you want.  Just keep in mind that you'll have to do the sleep cycle trick on every reboot (and make sure XTU is running to make the changes), and also anytime the charging status changes.  It won't allow you to mod the TDP while charging, but it works under all other circumstances.   The design spec on the 4300y is 11.5 watts for the package (and 100C on the chip) and I have mine set to 11 without issue.  Additionally, I doubt the 84C poses any problems.  I've not played with ThrottleStop so I don't know the equivalent settings, but setting the Turbo Boost Power Max to 11 in XTU allows the package to dynamically allocate power between the GPU/CPU.  Just having the headroom seems to help quite a bit.  I also undervolted the cache/CPU both by -55mV which seems to help lower idle temps and may or may not help at higher temps under load.  YMMV on stability, of course, but you can't do any harm by undervolting unlike overclocking.  XTU has a watchdog service so if you back yourself into a corner, it will reset everything to the defaults on a hard reboot.

Thanks - I noticed that the BAR-Edit settings definitely don't stick on reboot.  The XTU settings do (on mine at least) and load in the background via the service. 

I've done a bit of testing with 3DMark.  Using the XTU method I score about 22,000 in Ice Storm (that's with a -55.66mV offset on the core and -50.78mV on the cache and GPU).  With Throttlestop, I score about 16,000 (that's with the CPU at 1.6ghz, TDP at 9w).    I'm at a bit of a loss to explain it - in XTU the CPU clock varies from about 1.16 - 1.7ghz (mostly staying at the 1.16ghz end), but Throttlestop is more or less locked at 1.6ghz.  According to GPUZ, the graphics core stays at 800mhz under Throttlestop, but from the difference in results I have big doubts about that.

The grub_var method is somewhat permanent, from I entered it once months ago I haven't needed to again. I think a bios update may remove it tho

Has anyone been successful at and/or tried hard coding PL1?  Nothing I do seems to have any affect and it would be nice to just set it to 11W in the BIOS and forget it.

Would this work on a 7130 with the i3 4020y? I don't expect the same results but the i3 suffers from the same crippling power throttling which makes even civilisation V on minimum settings at 1366x768 unplayable. It starts off at a very high fps for a few seconds then drops down as the throttling kicks in.

It should do - the settings aren't be CPU specific, as far as I'm aware.  From memory, Civ V is very CPU intensive though, so an i3 might be pushing it...  Try Intel XTU to reduce your voltages a bit, which hopefully means you'll throttle to slightly higher clocks.

this worked perfectly for me once I figured out it doesn't work with the battery kb. Thanks for the work guys

I'm trying to replicate on my Acer w700 but I'm lost get the variables. Did you start with a doc like this? https://dl.dropboxusercontent.com/u/9950356/IDS.txt

Hi, thanks for replying.

You might be right but when I first bought it, it could run Civ at medium settings at 1366x768 absolutely fine. Now, after having updated the bios a few times, it's virtually unplayable at any setting. My only guess is they have ramped up the throttling a bit to save power. It's a bit irrelevant to me though as I have a keyboard case with the built in battery. I have already undervolted quite a bit which gives me an extra 50mhz or so of GPU but performance is very poor.

I would like to give the boot file thing a try, but I have a question: Where is this X:\efi\boot ? I can't find it anywhere.

Thanks for the help.

You need to create a folder called efi on a usb drive and drop the boot file in there.  X = whatever drive letter your USB drive has.


Once you've made the bios edits, you should notice a good improvement in your voltages in XTU (from memory, it does little to nothing without the bios edits).  Remember to also set your power profile to high performance in control panel, and configure you graphics settings for performance in the Intel control panel.

Mod works great. Using the IntelBurnTestV2 to measure performance, my Venue went from 12 GFlops to 27 GFlops.

Has anyone had luck with adjusting the fan trip point. The mods.txt makes note of addresses 0x1ac and 0x1ad as being Active trip points for fan speed. Setting these values have no effect. I've noticed the fan start up at about 57C and get higher at around mid 60s. Maybe another address needs to be set to unlock the fan trip points?

One other question. Address 0x39 default value is 0x00 so why is everyone setting it to 0x00? Is this a typo, should it be set to something else?

Thanks,
