Venue 11 pro i5-4300y Throttling

Anyone find a way to get past the throttling when the keyboard is plugged in? Is there any tools to edit dells bios that we could use to remove this?

Hi folks, how can I change the fan speed and when the fan chips in... Am thinking of making it come in at a higher temperature since I added heat sinks to my cpu cooler and they are doing very well... What values can i adjust?

Hi,

I tried this on my i5 4300Y venue and although the Thermal Throttling doesn't kick in, after a few seconds (between 5 and 15) the frequency drops to 1.2 - 1.3GHz and the temp. never goes above 68-ish.

At least compared to before, the GPU freq stays between 500 and 748 MHz whereas it dropped to 200 (!) before this tuning, but since I do video encoding i'd like the CPU to stay at 2 GHz for longer!

BTW: I changed all values in the mods.txt file, not just the ones with a * which were mentioned in the post. Was that correct? I then did it again and could see that they had been correctly changed the first time.

Any ideas?

I am gonna be making a video of the modz to my vp11 as I was able to get constant 2ghz and good video editing using premiere pro... Even using transitions. But it involves relocating the fan and modifying the heat sink.

Many thanks for this valuable peace of information.

Could you kindly advise if your method would also work on the Surface Pro 3 (i5 version)? The throttling problem has been driving me crazy and would really like to solve the issue once and for all. Any help would really be apprecitaed

the pro 3 throttles when its gets to hot something like 80 degrees c. The only way to stop it to to improve the cooling and it won't throttle. There are some YouTube videos showing people using a usb fan to help the cooling. Otherwise you might be better getting a pro 4 which is better for cooling

thanks for the tip, however I knew about this already, was hoping to find another solution which would avoid having to bring around a usb fan. As it stands I can't even play a low demanding game such as Fifa 13 without throttling. I tried programs such as throttlestop and xtu but none seem to do the trick.

Hi there, don't normally do the forum thing, but I have to say, HOLY SH*T!, I just got this tab off of ebay 2 weeks ago. $225, i5, 128gb (promptly swapped out for a 256gb faster m.2), 4gb ram.  I got the dock $20, the slim keyboard $17 the folio $9, all dell branded.  Anyway, I put the latest windows 10 x64 10586 on it, activated, removed watermark, did a bunch of benchmarks, updated the bios to a16, updated the dock bios, updated all the frickin bioses and firmware, still disappointed in the benchmarks.  Googled how to make this puppy faster and voila!

Stumbled on the is forum.  WOW! did the mods in the .txt, all of them, this thing is so much faster now, its no joke.  I have the latest bios A16 and have done a bunch of benchmarks and tests and did the efi boot mod thing all while plugged into the dock with a monitor attached and the difference is NIGHT and DAY over the performance it had before.  I even ran amiDUOS lollipop version and ran antutu,  I was barely getting 30000 and now i'm breaking 36000, 20% performance increase.  The increase is more than 30% in windows, but amiDUOS is a virtual macheen, lol.  

Totally impressed, you guys rock, first post, thank you!!!!!!

All the peeps who can't get it to work, uh, duh, put the .eft file on a thumbstick, put it in a folder called boot, inside a folder called efi.  I set my thumbstick as fat32 on a gui partition.  Thanks again!!!!!

I'm getting the same issue and I tried doing this using a windows 8 installer usb stick and then just formatting it with just the \efi\boot\bootx64.efi file and I get the same flashing before it just boots into windows instead of grub.  I tried changing the boot sequence so that my usb stick is first.  Any help would be much appreciated!

Hi There,

I know this forum is relatively inactive, but I am curious if there is a way to force the setup_var mods to stay permanent. I am seeing these values revert back to the originals after a battery removal, or if the tablet is not used/charged for a long period (and the battery loses charge). Also what exactly are the setup_var mods changing on the unit? 

Is there anyway to do the setup_var changes via a linux command line as well?

Thank you!

Thanks a ton to you and anyone involved in this. Felt like I just got a serious upgrade (that should've been stock).

So I did whatever I could to this i5-4300Y | HD 4200 | 8GB | 256 GB :

1. BIOS grub changed all variables suggested. Thermal Throttling only kicks in at >84C Package Temperature

2. Undervolting scheme: -70 -80 -60 (mV Core / Cache / Processor Graphics Voltage Offset respectively).

I'm guessing up to 10C reduction at idle. (guessing because temperature after mod was noticed when driving a 4K TV smoothly, and still managed to cut from ~68C to ~64C idle. Not to mention this was impossible before mod)

3. Turbo Boost Power Max 11 W: So far only crashed when used Sandra Lite Benchmarking. I'll just leave it as is.

4. Stripped back cover, USB Fan blew right its behind. 15 to 20 C shaved off. ~50C idle.

5. Power Options: High Performance profile (maxed out everything in advanced settings)

6. Intel Graphics Control Panel: Also everything favoring high performance

7. Windows Performance Options: Almost all pointless animation options unticked

With the above, XTU data:

Quick questions please:

1. Why does Processor Graphics Frequency (GPF) drop from ~850 to ~450 instantly whenever I run what should not have been graphics intensive games at all in 2015? (eg. App Store's Shadow Fight 2, Hungry Shark Evolution )

When Turbo Power is at 11W, ~5xC temperature.

Game's performance fine on main screen. Slow motion on 4K TV even at 1080p. GPF still drops not connected to TV.

2. What is your Grahics RAM ? Mine is 1.00 GB. More details here: en.community.dell.com/.../20866208

3. Is there any other possible tweaks you think could still be done for better (graphics) performance ?

Thanks a ton in advance again for your help !

This tablet doesn't have Dedicated Video memory, that 1GB you see is shared system(main) memory. It might allocate more in case of need. 1GB is overkill for this very very weak GPU. It would choke on 256MB of memory due to two reasons:

1. System (Main) memory is too slow for heavier graphics processing, it's also used as Main RAM, so speed is shared also.
2. All iGPUs (Integrated) are too too slow for heavier graphics processing. If you bought tablet for gaming, you've made a mistake.

This specific processor has very aggressive power management. It tries as hard as it can to be under power limits. So you might exhibit power throttling.

Sandra Crashes due to undervolting. Check the stability of the tablet by running memtest/prime.

I've failed to unlock throttling on this tablet. I've successfully changed those variables, but it didn't made a difference, even though i have same tablet with i5 4300y processor.

Thanks nam3k for your insights !

Soon after I realized that despite all the tweaks, the most important thing was my not understanding the mechanics of a sleep-wake cycle in order to actually unlock the Package TDP limit of 6W.

I don't really game, but I really need it to multitask well on a 4K TV. Just having couple programs opened (text editors), and a dozen web tabs alone would easily require a fairly constant 7-8W.

Dear Experts and Enthusiasts alike, your help in educating me with this situation would be very much appreciated:

Summary:
I woke up this 6/6/16 to the swollen battery, things have gone south since. Eventually sleep mode failed. Then currently IETU gives error.


Story:
The swollen battery was likely due to overcharging  from leaving it running overnight downloading / battery age etc.
After discarding swollen battery and while waiting for a replacement battery, the 7130 ran plugged in alone.

Things were fine this way until last night when I got home: instead of wake-from-sleep, it reboots.
This is (possibly temporarily) fixed by plugging in the battery.

However, a 2nd problem arises:
I can no longer adjust Turbo Boost's Extended Duration Maximum Power;

The following are incidents from 6/6 to 6/10 that I could remember that are possibly relevant:

• Use 7130 plugged in without battery
• Set All lid-closing while-plugged-in options to [Hibernate]
• Plug and fully charge new battery
• Set Dell Command | Power Manager Battery Setting to ExpressCharge (it reverted back to Adaptive eventually; or maybe I did it myself...)
• Remove new battery
• Set Hibernate to only the power button while plugged in. Everything else Sleep.
• At a school's lab: I forgot and connected ethernet cable to 7130 via a USB hub, then boot up, enter PXE boot console screen by accident (fist time).
• Manually forced shutdown, unplugged ethernet cable, rebooted fine.
• Hibernated with power button, left school lab.
• Wake from hibernating fine at home fine

Up until this point there was no sleep, nor Intel Extreme Tuning issue noticed.

• It is once I got 7130 to sleep in order to activate adjusted IETU profile however:

it reboots from sleep (black Dell splash screen; all opened Windows/apps gone) instead of waking up as usual.

• I have tried restarting, shutting down, switching lid-close options between Hibernate-Sleep to no avail.
• I noticed a bunch of Administrative event's critical errors from kernel power "...rebooted without shutting down first..."
• Before thinking about messing with the BIOS, I snapped in the new battery, unplugged all connected cables (USB hub, power, HDMI):
  • it boot up to "Invalid Configuration information - please run SETUP program.
  • Time-of-day not set - please run SETUP program...."
  • I presseed the volumeUp key to continue. It boots into Window. Wake-from-sleep is back.

• However, IETU does not comply:
  • Extended power is limited to 6W;
  • most fields grayed out;
  • I got an error when trying to propose an existing profile with Extended power at 11W

As you could imagine, this means that all activities the extra 5W could afford are now gone (eg. I was able to drive a 4K TV running 3D apps/games/videos at 11W for as long as hours prior to this)

Should I make some changes in BIOS, or doing this mod all over gain ? I don't really know.

Please advise and thanks a lot in advance for any pointers !

As far as i know you can't overcharge this battery using dell power supply, unless you hooked something up directly to the battery killing it's overcharge/undercharge/overvoltage protection circuit. But DELL nowadays produces everything with such low quality that i decided not to buy anything from dell anymore. So it's very possible that the battery was faulty and died after some time.

I guess the CMOS lost it's power due to some kind of power failure and all variables have been reset. Also check the CMOS battery with a multi-meter or a voltage probe. If the reading is >= 3V then the CMOS battery is OK. Although it's not the right way to test a battery, but for current situation it'll do. If the battery is faulty - replace it before doing anything else.

Next step is setting up your bios configuration. Check the sleeping states s1 - s3 for a simple sleep, s4 - hibernation. These states have to be turned on for sleep to work properly. Also the video driver has to be in perfect condition for sleep function.

Next you have to do everything you have done to disable all sorts of throttling using steps which are provided by other people. (Nothing new)

And check if everything is working again. Also don't forget to report to me about the situation ;)
