Experiment and conclusion on notorious Bios and turbo boost related issue.

Hi everyone,
Like everyone here, I suffered from the turbo boost issue and I decided to find a practical way to solve this problem,so .I conducted some experiments trying to find out the relationship between power strategy, graphic type, booting power source and the CPU frequency.. Here are my results:
Variable: Power strategy for AC/BAT: Max/Balanced, Max/Max(didn't try for balanced AC power strategy)
Graphic type: Integrated, discrete and Nvidia Optimus
power source when the machine booted(BAT,AC)
Testing model: W520 42762QU i7-2720QM Quodro2000M 16G Crucial M4 128G, 500G HDD, BIOS1.30
Testing programs: Intel Turbo Boost programs and CPU-Z

Notice the '800-2400' state, it is a special situation when CPU-Z occationally gives me a speed of approx 2400 when I tried some head-load programs, which lasted about few seconds and the frequencies went back to 800 or 1500(in most cases, 800) when I closed the program.
Conclution:
1. power stratagy will not influnce the cpu frequency.
2. booting power source and graphic types will do.
3. I'm sick and tired of pluging and unpluggin my W520.
4. I'm not a fan of Nvidia Optimus.
5. Lenovo did a terrible job on this issue.
6. I expect a same result for Bios 1.26
Practical solutions:
1.When you need a powerful W520, use Discrete graphic and plug your AC while booting.
2, For a longer battery life, use integrated graphic, and if you wan't to plug the AC, please turn off your machine and boot again.(not rebooting!)
Thank you for reading my post and sorry for my bad english

SomeOtherGuy:
Thanks very much for keeping us all informed about the "work in progress" on the BIOS and the Turbo-thing. That is thoughtful of you and will (hopefully) cut down on the amount of carping and complaining about this issue.

P67a-GD65 (B3) 1.19 BIOS weird turbo boost throttling down issue.

Hi all,
I just upgraded from 1.14 to 1.19 BIOS because of a keyboard detection issue. For the last few years, I always used Turbo boost OC 4.0-4.3ghz.
Since the new BIOS, when I run Prime95, I notice that at first, the OC works well (goes from 1.6ghz to 4.0ghz) but after a while, it will throttle down to 3.9, revert back to 4.0, then 3.9 and sometimes even 3.8ghz.
CPU Voltage never goes above 1.280v.
While I was using the 1.14 BIOS, it never got below 4.0ghz, so I can't figure out what's new in 1.19 that would make the CPU throttle below the values I set for it.
Note that the CPU temp never goes over 62c, so I don't think it's thermal related.
Overspeed, 2013 and C1E disabled, all other stuff at defaults. My core ratios are x40, x41, x42, x43
I also tried 41-44, 42-45, 43-46 ratios, and everytime, it goes up to the minimum ratio (say 43), then after a while, it will always throttle down to 40, 39 and sometimes x38 (rarely but happens everytime though)
Any ideas?

First, I want to thank you for your help... it is much appreciated!

ll settings being done in the UEFI/BIOS, not the OS right?
Yes, all within the BIOS. 'Change settings in OS is disabled.
When I tried to disable the CPU Phase Control, the PC hung on Windows desktop. Tried both SVID & the other one but no changes (same throttling)
Correction: ONLY Intel SVID mode works on my setup -- the other two will hang on Windows Desktop (ASP Mode, Disabled).
I tried the values you provided with no changes either. :/
I did notice something weird though.
1) I downloaded 'Intel Extreme Tuning Utility' to see if the CPU was throttling because of thermal issues.
2) when I tested the CPU stress test (20 minutes), the CPU went and stayed at 4.10Ghz the entire 20 minutes! no throttling at all
3) I then decided to test the memory stress test, Prime 95, LinX, OCCT and the CPU will throttle down to 3.7 sometimes, but mostly from 4.0 to 3.9ghz on those tests. What does it mean? no clue (yet)
Starting to wonder if it's not the CPU Phase Control. I might reflash 4.3 BIOS to see if it fixes this error (freezing in Windows desktop when disabled), but I'd rather keep this BIOS for now .
I'll keep looking for the answer (let's not forget, I'm able to get a fixed OC at 4.2 no problem when I disable EIST, C-Phases and set the CPU at x42 & vcore at 1.250v)
Again, thanks much for your patience & help!
P.S. I've seen another thread about someone having this exact issue, but didn't take notice back then since I didn't know I had this problem. And now I'm trying to find it, I can't :( Can't even recall if it was on this site or another one.
Worst case scenario, I make myself a 24/7 OC (even at 4.2 ghz... when not doing anything special, the cores temp are about the same as when at 1.6ghz 0.9xxv) I'll actually go do that @4.2 & keep it a few days to see how it goes power usage wise/temps/etc. But if you have any other suggestions, feel free to let me know, takes but a few minutes to revert back to this OC (saved and/or not long to set).
P.P.S. Gotta admit that at full OC 4.2Ghz (no EIST, C1E, etc), I can actually feel the PC being more responsive. Applications start faster (albeit just slightly, but noticeable), everything just feels more snappy. Starting to wonder if I won't keep it that way.

Help! my EFI System update says not supporting for mountain lion system! Why is that so? and i check my bios and boot rom version but still this happening? why is this happeneing and i cannot open hardware test?!

hello people i folow the steps of hardware test opening thing while starting up, but since i instaled mountain lion its not showingup!? why the **** is that so?!

Then it's not for your model MacBook Pro.

MBA2012 cpu multiplier wrong and no turbo boost in Windows7

MBA2012 Corei 7 2.0GHz/ MEM 8GB / SSD 128G.
core i7 3667U, it support turbo boost, max multiplier 3.2GHz (x32, 2core), or 3.0GHz(x30, 1core).
but check cpu-z 1.60.1.x64, it reports cpu multiplier x8 or x19.
core speed does not rearch 2.0GHz(x20) and can not turbo boost.

It is assumed in the model CTO in the initialisation of the MSR in EFI, is to set the Target P-State and 19 at the time of turbo boost, and the root cause of the bug (I originally set 32 is correct).
As a temporary workaround, in the application of the Throttle Stop, but it was confirmed that Turobo Boost working effectively, then, I tried to examine the state of the MSR at the before and after application of the Throttle Stop.
As a result, the following was found.
• The CTO model EIST, Turbo Boost is enabled.
• However, in the CTO model, Target P-State is closed when the Turbo Boost is set to 19-fold. Therefore, (Current P-State) can not be set to at least 19-fold magnification of the CPU.
• When you execute the Throttel Stop, so that can be set to 32 times the Target P-State of Turbo Boost, will be able to raise up to 32 times also (Current P-State) magnification of the CPU.
In fact, before and after execution of the Throttle Stop, appears similar to the following and see the state of the MSR. (The value of the MSR, Save Report(.TXT) of the "About" → "Tools" of CPU-Z in the, you can see)
CPU Throttle Stop before) cpu multiplier 19 (max cpu multiplier 19)
MSR 0x000001A0 0x00000000 0x00850089
MSR 0x00000198 0x00001CD2 0x00001300
MSR 0x00000199 0x00000000 0x00001300
⇒ enable EIST, enable TurboBoost, the current P-State 19, the target P-State 19
CPU Throttle Stop after) cpu multiplier 30 (max cpu multiplier 32)
MSR 0x000001A0 0x00000000 0x00850089
MSR 0x00000198 0x000021A0 0x00001E00
MSR 0x00000199 0x00000000 0x00002000
⇒ enable EIST, enable TurboBoost, the current P-State 30 , the target P-State 32
From the above, CTO model, at the time of initialization when the switch to Windows, it would have been set to 0x1E (0x00001E00: DEC
19) is target Performance State Value is IA32_PERF_CTL of MSR in the BootCamp is a cause of trouble, 0x20 (0x00001E00:DEC 32) you can determine it because it does not, and has been a state that does not increase the magnification was also an attempt to invoke the turbo boost when under load.
Core i5 In the standard model, so go up 26 multiplier, probably should be the value of the following.
MSR 0x00000199 0x00000000 0x00001A00

Mobo not allowing Intel Turbo Boost

Hey,
I build my own pc like 2 month ago and I'm experiencing problems with Turbo Boost. It was enabled when I got it and after a few days it was gone. The whole option wasn't there in the bios. Later i flashed the bios cause i messed something up and it was available again! So I enabled it again and now It isn't available anymore. Do any of you guys have an idea how to fix this?
CPU: Intel Core i7 4770K
Mobo: MSI Z87-G45 Gaming

Nope it won't.
Leave voltages etc at Auto as CPU should handle this without modifications.
However if you're running stock cooler, run an Intel Burn Test once you change the clock to see if it doesn't go too high than it does with the stock speed.
I am running my non-k i5 4670 at 3.8ghz and I had to manually change the speed, as there was nothing like Intel Turbo Boost
On 3.5 ghz i reach max 90 degrees while stressing :/
So I don't think 3.9 is reachable on stock cooler right?

H55M-E33 Turbo Boost Problem

Hi guys, I have an i5 750 installed on my H55M-E33, but I cannot find the option to turn turbo boost on.
Does this motherboard support it?

Quote from: fanta on 04-March-10, 05:17:36
Do you have the prerequisites for the turbo boost feature to be shown in the bios?
For my particular board p55-cd53, The turbo boost option is not shown unless intel EIST is enabled.
I did check out the manual for the board and there was no mention of turbo boost (well that I could find). Now with that said, they have your cpu listed as supported since v1.0 bios, so I imagine the feature is there.
Cheers
Thanks man that did the trick. I enabled EIST, rebooted and turbo boost appeared in the cell menu!
Strange there is no mention of this in the manual though.....
Cheers

How does the Turbo-boost works on the Intel i7?

Just bought the new MBP Retina and would like to know how the Turbo Boost works in my processor. Is it a regular upgrade like buying a new processor or is it something I could menage at the settings and have it boosted up?
Thanks,

Intel's definition:
Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:
Number of active cores
Estimated current consumption
Estimated power consumption
Processor temperature
When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.

How to Enable Turbo Boost?

I have HP Pavillion G6 (core i5 2430M) .. I want to know how to enable turbo boost?

Intel® Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the Thermal Design Power (TDP). This results in increased performance of both single and multi-threaded applications. Intel® Turbo Boost Technology 2.0 takes advantage of the power efficiencies introduced with having an integrated die for processor and graphics. It is also optimized for the new micro-architecture that was introduced with the Intel® Core™ i7-2xxx processor series and the Intel® Core™ i5-2xxx processor series.

how to activate turbo boost feature in new mac book pro

Intel® Turbo Boost Technology 2.01 automatically allows processor cores to run faster than the rated operating frequency if they’re operating below power, current, and temperature specification limits.
Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests a frequency higher than the rated frequency of the processor. Whether the processor enters into and the amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.

MSI X58 PLATINUM, the latest bios and how to enable turbo boost

1) Wich motherboard is ? MSI X58 PLATINUM or MSI X58 PLATINUM SLI ?
2) What is the lastest version Bios and where can i get ?
3) How to enable turbo boost in this motherboard ?
4) Thanks so much guys.

My bad. The obvious lack of your self research got the better of me. I do not take helping, if I can, lightly. This is new technology, & a lot of expertise is in short supply. I downloaded the manual on this board & read the bios section, & in CMOS Setup, you should find an "Enable" setting for Turbo Boost. If you don't, please contact MSI Tech Staff @ http://ocss.msi.com.tw Also, (in your manual), is a reference under "Intel Turbo Boost Tech", which clearly states "for further information please refer to Intel's official website". By your original post, CPU-Z says it's an SLI? What did you buy? Does it say on the retail box? At MSI's website, the X58 Platinum (not the SLI), has version 1.0 bios offered in three global region zip files. M7522v1.0 Euro.zip, M7522v1.0 ASIA.zip, & E7522v1.0.zip. J.T.N. is correct, the SLI board takes something else. Are both boards bios's compatable? I have no idea. Recommend step one as to confirm with MSI what board you truly have & go from there.

[P67-GD65 B3] Safe way to flash 4.2 official bios and why.

Hi all!
I am still trying to remedy my problem with too high (~1.43V) voltage while 4.5GHz OC (turbo or not) with "vdroop low" enabled. Now I am on 4.39 and it`s ok on (non turbo/manual x42) 4.2GHz and auto voltage (it`s ~1.288V while Prime, etc). I know that 4.20 official bios gives % vdroop settings. I want to try it to avoid my problem but I can not find 4.20 package ready to go with MSIHQ flasher. Actually all 4.xx MSIHQ versions go from 4.3x.
I am wondering if it is possible just to compress "valcheck.com" with 4.20 official bios file and throw it via Mode 1 to MSIHQ(?)
BTW: Maybe it (flashing 4.20) does not make any sense because "%" vdroop on 4.20 will not give me anything higher then "Auto" voltage settings. I think I need ~1,38V to get stable 4.5GHz. Any other ideas?
I could try manual voltage for CPU but I want to stay with energy saving c-states. I am using C1E with my non turbo OC.
I know You can find my problem a bit boring but maybe forum's Gurus could give me a green or red light(?)

Just to report!
Yesterday I finally tried to down-flash from 4.39 to 4.20 with MSIHQ. Risk taken Happily it was success!
But boy ... I should read carefully comments about 4.20 bios (grammar lost). I did not know that on this bios 100% vdroop is not ... How to say it? It is not 100% of "vdroop low" but rather 100% of "vdroop auto". So it not helped me with my main problem. I am now back to 4.39 beta bios.
BTW1: After some tests, I found that while on CPU voltage on "Auto" my CPU max voltage is ~1,29V (never more, it stabilize more or less from x40 multi CPU) while stress testing. Switching to "Low vdroop" I get above 1.4V just from x40 multi. Something is not right. It goes up with higher multi.
I tried to workaround this by Control Center. Switched to lower multi in bios, switched vdroop to "low" (voltage was OK and below the 1,4V line while stress testing) and then bump up multi in CC. Guess what ... Voltage was also bumped to the same (too high) values.
BTW2: I started to think that above problem may be my fault. From start with my P67-GD65 I experimented with OC Genie and maybe I switched some values or even reseted CMOS while using OC Genie (I know that was warning about it). I don't know, but maybe it damaged something and my motherboard behaves like this for good :/
I think that it is the end of my experiments. Bios 4.20 (% vdroop) was my last resort, but it failed.
Big thanks for all that tried to help me . It started 07-April-12:
https://forum-en.msi.com/index.php?topic=158139.msg1161554#msg1161554
I have to stay on x42 with ~1.288 voltage or go above x45 with more than 1.43V.

Y50 uhd 48hz frame lock can be fixed lenovo must update bios and other seriouse promblems.

No it doesn't help at all.
Especially when I can be corrected.
Lenovo is lazy and disrespectful to its customers.

Hello I have discovered the y50 Uhd refresh ratecan be fixed the promblems stems from this orginally. When the y50 came out theIntel® HD Graphics 4600which was used for display could only run uhd at 30hz so lenovo released a custom driver and bios too make it run at 48hz with windows 10 being released intel has updated the driverit now features dx11 and dx12 support and can run uhd at 60hz I completely deleted the lenovo drivers and unistalled them restartedand install intel drivers because deleting and the drivers is the only way you can install intel drivers as the lenovo drivers act more like a virus and locks you in too only using there drivers i quickly notices a shaper image and more deeper colors in the screen but it was still capped at 48 which leads me to the conclusion that indeed lenovo capped it in biosor else it would of ran at 60 hz thanks too the new drivers also another thing lenovo did was block the ability to choose xmpfiles for highquality ram in bios this needs too be fixed because this a gaming laptopand lenovo you need to leave the bios alone you cant update you nvidia driversyou cant update you intel drivers and you permently limit people and they can not work around because simply you want to also lock there bios It feels like I was loaned a computer and i dont own it you cant pick and choose xmp setting like a real gaming laptop you need to fix this pronto stop locking everything.

Hyper-V stopped turbo boost and cpu park on my intel 4702mq processor?

Hi I just got my lenovo thinkpad e540(core i7 4702mq ,256 hyper-x ssd, nvidea geforce 2gb...)
I installed windows 8.1 and server 2012 r2 to separate personal and business use.
The cpu was running at many speeds to preserve battery life (between 0.7ghz and 3.2ghz on turbo boost). After installing the hyper-v role, the speed in task manager is stale at 2.19ghz and
all the cores are not being parked even when the system is idle, is this a bug or that's just how virtualization work??
Thanks!!

Quote from: NovJoe on 22-November-09, 01:24:35
Performance mode probably means having higher voltages or higher "optimized" settings to run the system. Fail safe mode already spelt out its intentions to keep the system from failing.
For details, you can contact MSI for more information.
As I stated in my first post, I carefully went through all of the BIOS settings and the only thing I could find different between 'default' and 'optimized' is the setting for 'Intel Turbo Boost'.
I will post a question on the BIOS board about any other differences, but until then my original question remains...
...does anyone know of any problems (and hopefully FIXES) with the P55-GD80 and Intel Turbo Boost?

Speedstep or Turbo Boost and Logic CPU Meters

I'm currently weighing up selling my remainding outboard synths and going the plugin route, so last night i loaded logic up with as many plugins as i would normally use in the equivalent of hardware audio tracks to get an idea on CPU Usage, Heat build up etc. (I run on a macbook pro in clamshell to external monitor).
Just to note, i don't normally run with the CPU meter displayed so this is all quite new to see what's going on under the hood, especially as i was making a point to watch it.
What i noticed was that the CPU meter went up very quickly to about 20-30% across all cores after the initial plugins that i loaded up.. But after that point i could load several audio units and record with them, yet they were using nowhere near the same kind of overhead the initial few used.... Dare i say it, they were hardly noticable on the load.
Now, i know that intel processors have had speedstep in the past which would slow your cpu down until the demand was there, and i'm aware that the modern cpu's have Turbo Boost which increases the core speed if required.
So, what i'm curious to know is that do plugins generally cache and have less draw on a system in multiples, or is this a case of my CPU ramping up it's capability the more i pushed it?

hey fmortz,
could you go to > http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70498
and do a bios update.
