K53TA.. The best deal ever... could be!

i'm afraid to use amibcp to save a bios. I did that a long time ago, and got a corrupted bios file.

I need to ask around to learn the proper way.


Anyway, if you install the mod, test the fixed mode and see if you are able to run high performance mode, then power saving mode, then back AGAIN to high perf mode. Report back results. I want to see if this is a consistent bug.

that's the only major bug. It wouldn't let me go back to high perf mode for the second time unless i booted to safe mode and turned the dgpu back on through device mgr. Switching to powersaving mode the first time permanently disabled the dgpu such that windows couldn't see it.

You'd think that AMD could easily program CCC to handle crap like this.

good to know i'm not the only one with powersaving bug. However, it won't let me reenable the dgpu without safe mode. Device mgr just doesn't see it even after scanning hardware.

hmm. good idea. I will try to see if I can switch between dynamic mode and fixed high perf mode without crashing.

yes, turbo is almost useless, however I don't see a need to turn it off, especially after anandtech benched the A8-3500m with turbocore enabled, and it actually make some single thread apps faster.

 

just wanna say that the bios have a option to enable SATA III (6 Gb/s) and a Japanese guy has already tried it out.

maybe people with SSD could boost their speeds.

 

Hey I think this is interesting (He managed to get a SS down)!!!but the bench show he bench for 26min already

it's worth mentioning that japanese people made this great wiki page ASUS K53TA ???wiki

 

Hmmm , let see if there is any good stuff

Nothing new, but the site look nice xD. No need google translate since I read chinese fine

 

baiii was right.

I think I finally got a nearly troublefree fixed <->dynamic switching experience.

As long as I only switch between high performance gpu and dynamic switching (without ever touching powersaving gpu mode), the dgpu doesn't disappear from device mgr, and I can switch back and forth as much as I like.

Since dynamic mode is basically power-saving, you don't ever need to select power saving fixed mode.

I set high perf fixed mode, rebooted and checked CCC to make sure it would stay in high perf.
Sure enough, both gpus were still listed in device mgr.
Then I set dynamic mode, and both gpus were still in device mgr.
Did this a few times back and forth, and all was ok.

The only bug is when switching from high perf back to dynamic, Windows won't shutdown completely that time, and I have to hold down the power button to shutdown. As long as you don't switch gfx mode, subsequent reboots are ok.

 

Doing a reboot before switch should ensure a 90%+ success . But graphic switching probably would not be a daily routine .

 

So let me try to summarize Link626 & baii directions on how to use Bios; [Big thanks to there148's for the Bios file]

New Bios Summary:(purpose: to unlock fixed dGPU mode so openGL apps/games will use the 6650m instead of the slower 6520g card.)
0. First flash Asus factory 212 Bios, then use winflash /nodate to flash modded Bios 212.

Here's the BIOS 212 mod FILE first brought to our attention by there148:
http://forum.notebookreview.com/8392140-post2750.html (Turbo Boost enabled so K10stat works like before)- by Link626. THANKS!!

or there148's original file

http://forum.notebookreview.com/8384691-post2676.html (Turbo Boost disabled)-by there148. THANKS!!

REMEMBER TO USE Nodate argument when flashing modded Bios (since it will warn it is an older file): Take the Winflash shortcut and right click for properties. Type /nodate after target. It should look like this:
Program Files (x86)\ASUS\WinFlash\WinFlash.exe" /nodate

1. On "Switchable Graphics Method" Screen (see first image below):
Only switch between High performance gpu and Dynamic switching (without ever touching powersaving gpu mode)
High Performance (Fixed dGPU) = Select the graphic processor manually or based on power source.
Dynamic = Select the graphic processor based on application needs

This should allow switching between High Performance (fixed 6650M) or Dynamic (6650M+6520G Dual GFX/Crossfire mode).

**BUG1** Avoid selecting between High Performance and Power saving gpu on "Switchable Graphics" screen or else you will be stuck in power saving mode. So don't bother ever wanting "6520G alone" or else you will be stuck in power saving mode and required to do the "safe mode reboot dance" described by link626.(see below)
reference post of Bugs & Issues:
http://forum.notebookreview.com/8386595-post2707.html
http://forum.notebookreview.com/asus/601808-k53ta-best-deal-ever-could-272.html#post8388416

**BUG2** Pay attention to WHEN you switch from Manual Fixed to Dynamic mode : PC WILL HANG ON SHUTDOWN during the session you made the switch.(If PC hangs on shutdown then you will have to illegally shutdown by pressing power button for 3+ seconds.)

This bug applies to AMD 12.1 drivers. The PC always hangs on shutdown if you made any number of switches between modes. It will only hang one time. But on next reboot, it will not hang on shutdown unless you switch between modes again.
This Bug can be avoided if using 11.12, 12.2, 12.3 and later mobility drivers. But new bugs are introduced with the above drivers. Your experience will vary depending on which graphic drivers are installed.

**Note: New Bugs introduced by graphic drivers:
11.12 - BSOD instability when using Fixed dGPU mode and new Bios mod.
12.1 - worked very well with the new BIOS mod. but PC hangs on shutdown if you switch from Dynamic--> Fixed or Fixed-->Dynamic.
12.2 & 12.3 drivers -(K10stat with turbo boost "on" caused hanging on shutdown regardless of the Bios Mod being used; Msi Afterburner requires missing ATI dll files; Power4Gear needs to be avoided for CPU high performance speeds to be maxed; dGPU(6650M) may have high idle speeds resulting in higher temperatures.
12.4 drivers - FIXED MODE using bios 212 mod has BROKEN performance(slow speeds) with this driver. But in Dynamic mode drivers still work fine.
But with workarounds to some of these bugs, it may be possible to use any of the 12.x series drivers with the new Bios Mod 212. (see WIKI latest driver notes for bugs and workarounds.)

2. On "Switchable Graphics" Screen (see 2nd image below)
:AVOID tampering with "Choose A Graphic Processing Unit":
(So AVOID selecting POWER SAVING GPU MODE) - Just leave it alone and do all your selecting on the "Switchable Graphics Method" Screen.

3. Safe mode Reboot Dance (As quoted by Link626)

http://forum.notebookreview.com/8386595-post2707.html
4. Two Bios mod files have been made - One Bios file with CPU Turbo Boost set normally like factory and a second Bios file with Turbo Boost disabled. In the second file there will be no boost (B0) and you will have to manually set K10stat (P0) clocks higher if you need eg. 2.0,2.1,2.2, 2.3,2.4,2.6 GHZ etc.

 

Ok, so I downloaded this148's bios mod (thank you btw) and I played skyrim with the dpgu on. I see better performance with the single gpu, rather than with crossfire on. Now I'm going to test out bf3 and see what I get, hopefully its just like Skyrim.

Edit: WOAH, MUCH better fps in bf3 with the single dgpu only. I'm very impressed, I am able to play on ultra (with some the anti post, alias, motion blur, etc., turned way down, but overall amazing). BUT, I have to make the screen size a alot smaller than usual, but still I am able to play on ultra and get a solid average of 45 indoors and about 30-40+ outdoors in Operation Metro.

 

Tested myself BF3 may be 5% to 10% fps increase depending on map and number of people, Everyting on low 1280x720 Krikland 64p 35 50 fps. (30 45 before), crashed twice some DX error, may be because i am on 11.12
but on Sharaqi peninsula not much fps increase 30 to 40
so its a mix bag for bf3
For opengl tesitng i used half life counter strike 800x600 ogl 32P MP and sad its still not solid 100 fps, on intense firefight it drops to 70 so same as dynamic swithching, so no improvement.

And lastly temprature as stated in dv6z thread on fixed high performance the temp idles at 49 to 50C even at 700mhz and 0.7125 v (a solid 10C hotter)
if change to dynamic swithc it idles at 44C (5C more)
but on official 212 it idles at 39C

 

In dynamic mode, there should be no reason it would idle higher than stock bios.
It performs exactly the same as stock dual graphics (both crossfire on and off).
In dynamic mode, when you're browsing the web, the dgpu should be off already, since the browser is set to power-saving.
You can use AMD System Monitor to verify no activity on the dgpu.
I watched an HD video on youtube, and only the igp was used.

The 5C difference could just be a difference in room temps. Did you measure the temps within the same hour and let it cool down?

I'm using dynamic mode right now, and Hardware Monitor tells me my temps are within normal daily range. Currently 40c.
Fan is quiet. no fan kick in. The lowest temp I've ever seen on my unit is 37c, and that's only if my room is freezing. Usually idles around 39c.
I'm OC'd to 2ghz.


last i remember, half life engine is very cpu dependent. so it's not surprising you're not seeing much improvement.
also, the lower resolution you use, the less improvement you will see.
You need to bump up the resolution to 1600x.

 

yea i did all the test on fix mode so dynamic mode might be as efficient as you say but can't verify now, might be the after effect of bf3 season. Wont understand why dedicating fix mode causing cpu temp to rise, i switch back to official one for now. am too on 2g P0 1.02v
can't be true for Counter strike its whooping 10 years old now, can any one confirm realworld ogl performance other than that cinebench

 

How do you do the "/nodate argument" to pass the date check on winflash? The modded bios is giving me a hard time, so I want to revert back to 212 bios. Also, I cannot access ccc in safe mode to do the "safe mode reboot dance" . If someone would help me out that would be great.

 

I never did a nodate argument bios flash but found some instructions here: search for (If you wish to downgrade...); it says you need to start a command prompt to do it.
http://forum.notebookreview.com/asus/174395-bios-update-guide-asus-notebooks.html#sec:winflash
I haven't tried the new modded bios yet, so can't help much. But the safe mode reboot dance directions are in the summary>> http://forum.notebookreview.com/8386767-post2709.html.

I'm still slow at trying the new bios since I want to upgrade to AMD 12.2 driver first and then flash to 212 official bios & compare performance at stock bios to the modded bios on games like Skyrim,BF3, Crysis2, Deus Ex, and other older games. And then make up my mind whether to keep it or revert back. But we should all be wary not to flash bios too much since it can be a risky procedure. I may end up keeping it on Dynamic like Link626 just to avoid flashing bios again. (Since it's essentially the same as running dual graphics in AMD ccc; However I've always run CCC with disabled dual graphics instead of enabled dual graphics since it seems to have less microstutter--so not sure yet....; but I could always save Fixed mode for all PC games like Skyrim and Dynamic mode for web browsing and other common tasks.)

 

create a shortcut for winflash, go to shortcut prperty in the target add /nodate after the actual exe link. someting like
"D:\Program Files (x86)\winflash.exe" /nodate

 

I currently have dual graphics disabled. in other words, dynamic mode with crossfire turned off.
I could turn crossfire on too, if i want.

it really doesn't hurt to run the modded bios.
other than the disabled turbo, if you don't switch to fixed mode, it behaves just like stock.
With dynamic mode, games will still use the dgpu. You don't need to use fixed mode for that.
Even my temps are stock. Currently sitting at 39c like it always does.

The only time you'll ever need to switch to high perf gpu fixed mode is when using openGL apps.

If you want to flash back to stock bios, just use the easyflash in the bios.

You're not supposed to access CCC in safe mode. Make your CCC changes in normal windows mode.
If you're stuck in powersaving gpu mode, when you try to make changes to CCC in normal windows, it will appear like nothing changed, after you click Apply. That's OK.
Go ahead and boot into safe mode, and turn on the disabled gpu in device manager.
Then reboot normally, and CCC should now show the changes you tried to make 2 steps before.

So basically, make your changes in CCC before rebooting to safe mode.

As long as you keep it on High performance gpu in fixed mode, you should have no major problems.
Then, when you want to save battery juice, just switch over to Dynamic mode.
Don't choose Power Saving gpu, because that will disable the 6650m, and windows won't find it anymore until you enable it in safe mode.
That also means- DON'T tick the box next to "automatically switch to powersaving gpu when on battery"

 

Thanks for answering my question, really appreciate it guys . Thanks dchinu, your directions worked flawlessly.

Oh, wow, should've done that, but the thing is, every time I boot into safe mode, right click on desktop and click on AMD Vision Control Center, then switch back to regular mode, I have to reload my drivers the next time I log into my account. Is this supposed to happen?

 

dGPU and CPU share heatsink, so fixed mode with raise CPU temp.

 

no. you're doing it wrong. If high perf gpu is setup correctly, you never have to reload drivers. you never access CCC in safe mode. You do it during normal Windows mode.

The trick is- you switch ONLY between high perf gpu fixed mode and dynamic mode.

So, the First thing to do is to make sure High Performance gpu mode is enabled and works.
You do that by setting it up in CCC, under normal Windows, not safemode. (if you were previously in powersaving gpu mode, and now try to select high perf gpu, your selections may appear to not stick. it's ok. move on)

Then you check Device manager and make sure both gpu's are listed.
If the 6650m has disappeared (because you previously messed with power-saving gpu mode), then you reboot into safe mode and open device mgr in safe mode and enable the 6650m. (If it has not disappeared, you don't have to boot safe mode.)
DEVICE MGR is the only thing that needs to be opened in safe mode, if safemode is necessary.
Then you restart windows normally.

After windows starts normally, open CCC, and you should see it in high perf gpu mode. (If you don't see it, you did something wrong. start over.)

OK, now you're halfway there. Reboot one more time just to be sure high perf mode sticks. (It should)

Now you can switch to dynamic mode via the "Switchable Graphics method" menu, and "select gpu based on app needs".
screen will flicker, and you'll be in dynamic mode.

You can also go back to high perf gpu fixed mode right away by "select gpu manually" option. No rebooting necessary.

You should now be able to switch back and forth freely between the two Switchable gfx method options.

To keep it working, you should never set power-saving gpu in fixed mode. Just pretend the option isn't available.
Once you have high perf gpu mode, don't ever mess with fixed mode settings again. Whenever you use fixed mode, Leave it in high perf gpu mode only.

Switch only between high perf gpu mode and dynamic/crossfire mode..... and the only minor annoyance you will see is that your pc won't fully shutdown/reboot if you switched graphics mode during that session (hard drive will turn off, and it will hang at a blank screen), and you'll have to hold down the power button to shutdown.

In subsequent sessions, if you do not switch gfx modes, then shutdown/reboot will work normally.

As long as you switch only between high perf gpu and dynamic, windows should boot up normally without having to reload drivers.

and just to reiterate, the ONLY time you ever need to use fixed mode is if you're using openGL.
all other times, leave it in dynamic mode, since directX games will still use the dgpu if you tag it High performance.
There should be no extra benefit in using fixed mode for dx games.

yeah, it does.
but that's why you switch back to dynamic mode to bring it back to stock temps.

37c dynamic mode baby......... no heat problems here....

 

Can i ask how did you uninstall it?I dont find it in the list of programs(control panel>uninstall a program),?
When i press win + x,there is no option for screen brightness but if restart the computer(when the screen brightness is up as it should be) there is such a option,dafuq?
One more question(actually i asked this in some pages ago but no one answered),i uninstalled the preinstalled stupid games from Asus and that f*ked the whole os up,the windows explorer crashed every minute after that.I needed to restore the system to a previous point to fix it,anyone know why is that?

 

I flashed the modified Bios and made the changes.
Also overclocked the videocard slightly to 640/960 and the CPU to 2.3 ghz @ 1.0875V

Everything is working great! In cinebench my OpenGL score went from 20.41 FPS to 35.01 FPS, that's sick!

Very happy now =D

 

Wow, thanks for explaining it for me. I finally understand , thanks you.

 

Lol, one problem. After flash the modded bios and OC CPU + GPU i can't change my screen brightness anymore with the fn+F5/F6 buttons. Is that correct?

 

When you fixed on dGPU , yes. But you can still change it within where you change windows powerplan.

 

f5/f6 still works in dynamic mode.
like i said before, if you don't need fixed mode, revert to dynamic mode.

 

Refurbs are back in stock at Newegg for $410.

Yeah, but why should i ever get back to dynamic if i can stay in fixed mode?
Fixed mode is faster =D

And indeed i can just change the brightness in Windows without the shortcuts.

Or is it bad to stay in fixed mode?

 

it's not bad to stay in fixed mode, except for more power usage and heat and broken fn5/6 , but it's not faster.

if you turn off crossfire in dual graphics mode, it is just as fast as fixed mode in non-openGL apps.

 

Thinking of picking a few up for friends and reselling them for $450. Make a quick $100-200.

 

The C/P is just insane, Maybe i should make my bro give up on waiting near D3 release date to get a new computer.

One of the newegg say they put a 1080p in this? hmmmmm

hi i have taken this k53ta
i am trying to overclock it by using k10 stat
but i can only overclock 1 core at time only
is it possible to run all 4 cores at 2ghs or 2.4 ghs or even more
please guide me
i am also reading this forum from long time when there128 released fix 212 bios then i decided to take it , still on stock bios 209
screen viewing angles r good than my acer 5542

 

i installed Rage, and the game is playable in fixed mode. uses dgpu.
frame rates seem a little better than igp.

however, interestingly, the igp can now play Rage too, since amd optimized the drivers.

Of course, rage has crappy performance because of megatextures and hard drive thrashing.
Now that i've tested Rage, I can now uninstall this crap game.


I also tested furmark opengl benchmark, and in 1280x720, the igp got 7 fps, and the dgpu got 12 fps.


I don't know if my pc is acting up, or if it's the modded bios, but i noticed the cpu is skipping all the P-states when monitoring with Hwinfo64.
It goes from p6 to p0, and nothing between.
I remember with the stock bios, cpu would hit p3 p4, etc.

This might be a side effect of c6 and turbo disable ?

 

Thanks for testing Rage and saving me the trouble to ever getting the game, as I was always curious of its performance...LOL (crap game & too big at 20+GB) ...Thankfully most of the good games are Directx9 or 11 & under 20GB in size. But maybe this mod will be useful for other openGL games in the future (eg. Doom4 or Prey2), hopefully at a playable 25-35FPS.

I finally joined you & installed the new Bios and updated radeon drivers to 12.2 from 11.12. And everything went smoothly . Still testing...(games, temps, and gpu activity, FPS).
I remade some of my K10stat profiles to take into consideration no boost. I too noticed the jumps from P6 to P0 in high performance cpu mode. So looks like another aggravation to live with, not as much control. I hope we see another Bios modd that brings back stock turbo.

In new BIOS in fixed mode, I noticed some games that didn't recognize the dgpu can see it now, but the igpu still shows activity like crossfire is still occuring even though I set "disable dual graphics". I observed this in "MSI Afterburner GPU2&3 usage graphs."(I thought the dgpu was supposed to be active by itself with no 6520G, but this doesn't seem to hurt anything).
--update:
1)Batman AC doesn't run fast in Fixed Mode - only getting FPS 40max 30avg (in dynamic mode I was getting a great 60max 46avg) so not sure why this game isn't performing fast in Fixed Mode..MSI afterburner again indicates both 6650 and 6520g is active in crossfire when I was expecting the 6650 to do most of the work. Maybe something is wrong in my power profiles.
2)BF3 in single player campaign. Getting between 45-65 FPS depending on action level. But seems very good in Fixed mode. MSI again indicated both gpus were active in crossfire. (Dynamic not tested)
3)Skyrim seems equal or possibly smoother with ultra settings. MSI indicates crossfire is active.(Dynamic not tested)
Nice benchmark comparisons you made, so I guess it shows how close the 6520g and 6650M are in performance, with only 5 to 10FPS improvements in openGL games--so not a magic pill but better than nothing. I'll just save Fixed mode for OpenGL games while Dynamic mode will be used for most of the other games. Also temps are hotter by atleast 5-10C on fixed mode.--same thing Link626 said.

 

I'm experiencing the same activity. Using 12.1 drivers though. Java based emulators/apps are now able to utilize the dgpu now, which was impossible before. However, the 6520 gpu still shows a lot of activity as well, like it's operating in crossfire.

 

There is much more light and universal program for a benchmarking:
Unigine Heaven Benchmark

It has a DX10, DX11 and OpenGL mode, tesselation, AF and AA options.

As for iGPU activity - it can not be zeroed completely due to the fact that it must "transfer" picture from dGPU to screen.

Edit: For monitoring the AMD Fusion GPU`s AMD System Monitor must be used.

 

is it possible to run all 4 cores at 2ghs or 2.4 ghs or even more
please guide me

 

Yes but more heat (50C & higher) will be produced if it's running at 2.4 ghz or higher all the time.
Basically download K10stat program and create appropriate clocks and voltages. Get ideas from examples found below if you are not sure. You are supposed to test your settings for stability issues because all CPU setups act differently but if you follow the exact settings below then you should be ok. Here are links to follow below:

I noticed Baiii stated we don't need turbo speed if we set K10stat to Enable clock control, and set clock control to unganged. I did this and it works now, I see different P states and more efficient & maybe cooler cpu.
http://forum.notebookreview.com/8386384-post2701.html

 

The reason for unganged is that you can get a high clock on 1 or 2 core w/o getting all the heat up, by setting the default 60/20 to something higher like 80/40 to keep the unused core down.

If you are not using k10stat for clock control, meaning windows is dealing with it, windows have tons of complex algorithms to manage the clock. I used to set the step up/down threshold high like 80/something for windows but it still go right up when it detect idk w.e. Maybe the bios option have something to do with windows internal clock control, I am not sure.

 

There is hidden Windows power setting dealing with policy of p-state switching. And cases are:
- one p-state per step;
- straight to the optimal p-state;
- up to maximum p-state.

Edit: Actually two of policies - increasing and decreasing of p-states

 

ok. i turned on unganged mode, and also see middle p states.
so i guess that problem is solved.
i think i had unganged on a while ago, but somehow got turned off.
I rebooted and ran it at default 1.4ghz, and it looks like cpu jumps from p6 to p0 too. so must be default behavior.

I also see some light activity on the igp when using fixed mode, according to amd system monitor, but I pay no attention to that, as the dgpu is pegged at 99%.
light igp activity + heavy dgpu activity does not mean crossfire.
any light igp activity is not being used to render opengl games/apps.
I tested it in furmark, and it shows fulltime dgpu activity, with 0% igp.

no, it IS a magic pill.

the performance is scaling, meaning that the 6650m gets at least 50% better performance.
you can't compare the two gpu's by subtracting framerate.
if the igp got 40 fps in a game, the dgpu would likely get 60+fps.

the dgpu has 50% more shaders, 50% faster clock, and 35% faster memory. so it's not surprising it gets 50%+ better performance than igp.

remember in cinebench 11.5, performance is 20fps vs 31+ fps. 50% improvement.
furmark is 7 vs 12 fps at 1280x720. That's like 70% improvement.
at 800x600, it's 9 vs 15fps, iirc. so around the same 70% improvement.
and that is expected based on hardware specs.

so, there are tangible improvements.

where do i edit this hidden setting?

 

There is registry key

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00]

("Processor Power management settings and configurations").

Under it you will find a bunch of subkeys with names also in GUID form. If under such subkey you see a value "Attributes" (of type REG_DWORD) equal to "1" than it is hidden and you unhide it by setting "0" instead of "1".

Edit: Sorry, I forgot: after that you go to the "Power Settings" in "Control panel" and click link "Change advanced power plan settings" - after clicking you view a dialog with settings in a tree - so there you will find all inhidden settings. (see my old post)

Edit2: Mentioned policies are:

Great work everyone! Finally, after owning this laptop for 7months, I think we've unlocked, tested & come close to finding all of the laptop's full capabilities & full potential. Now to have fun and put them to good use every time a new game comes out this year! So it's official we can all live with Bios 212 modded the way it is.

 

And for keeping the cores down there are many hidden settings dealing with so called core parking.

Edit: I wrote about it

 

thanks man
i figured out problem of mine
i was changing freq of bo state ===
now i change p0 2600 v 1.25 done video encoding fps =100 stock 1.4ghs was around 70 frames/sec maximum temp is 84.6 which is ok for me as if i do same endoing on my i3 i get temp of 86
very happy now

 

I used to do that too, but the Dv6z CnQ throttle big time if I run the iGPU and dGPU 2 hard. If I disable CnQ, windows clock control doesnt work anymore. So I just stick with k10 control now.

 

Since there is one up%/down% setting per a p-state - but not per a core - I doubt that k10state controls namely cores loading. Switching p-states - yes. But switching the cores - no.

Edit: But Windows 7 has policies for cores loading control - that was my note.

 

it turns out we can edit the bios in amibcp 4.53 without corrupting it.

so i modded the factory bios and turned on fixed mode, while leaving everything else stock, including c6 and turbo.
Also, there was a minor bug with the previous fixed mode bios- it would make the "Main" menu tab disappear from the bios.


you can download this new modded bios here- K43TAm.zip (c6 on, turbo on, fixed mode)
I am using it right now and fixed mode is still working.

or, if you'd like to do it yourself, all you need to do is open the bios in amibcp 4.53 and change the PX fixed mode to enabled. Then click the Save button.

(re)flash factory 212 bios, then use winflash /nodate to flash modded bios, as instructed in previous pages of this thread.

 

THANKS link626!!
I just reflashed yesterday with your updated Bios.
Now everything is perfect. I remade my K10stat profiles once again If we don't want boost we can always uncheck boost from K10stat profile.

I posted all your posts about New Bios 212 mod in the SD wiki and my past link with instuctions to spread the word.
