How to Enable Intel Dynamic Acceleration (IDA) on Both Cores of a Core 2 Duo

That's alright. I'm not going to keep it anyway.

 

Great Tool! Just enabled IDA and undervolted to 1.05 volts on my Dell D630 with a T7300 going from 2.0Ghz to 2.2 Ghz using the A17 bios and disabling speedstep.Very easy to do and a great little performance bump. Might convince me to not buy a T9300 to run my VM's.

My notbook is y450,cpu is t9800,and i mod F7731B4C-58A2-4DF4-8980-5645D39ECE58.ff with the code：
seg000:000000000000168F B9 A0 01 00 00 mov ecx, 1A0h

Everything is correct but you forgot to patch bts (bit test & set) to btr (bit test & reset). " bts rax, 14h" in the above instruction code will set MSR 0x1A0 bit 20 to 1, which means EIST is locked. " btr rax, 14h" will reset MSR 0x1A0 bit 20, which means EIST is unlocked. So, they should be like this:-

Code:

hy there,
would it be possible to patch a bios for a lenovo x200?
would be great! i can use the extra performance for realtime audio processing.
thanks in advance!

 

It might be possible to modify the X200 bios for an extra 133Mhz performance (P8xxx/T9xxx) by following Kizwan's instructions here. Please do post your resultant modified and tested bios so it can be added to this list.

 

Did you patched both instance?

i'm sure i patched both instance.




after flash bios,it's still locked.

 

can you post a screenshot of Throttlestop's main window, the initial one after starting TS.

How did you reintegrate the patched module? If with Andy's tool, what version?

 

I used ThrottleStop3.0.and i'm sure i patched both instance,and flashed the bios.but it's still locked.

 

Sorry it doesn't work for you. Pls tell us how you integrated the patched module.
I tried it myself and got an error message from Andy's tool version 1.90.

 

I used ETU-DASM v2.35 to mod file.
Here is default file:

Here is moded file:

You patched not correctly.
I did for you. Try first Version1.zip. If it doesn't work try Version2.zip.
Just for my information. How do you integrate the changed module(ROM) into the BIOS? How do you adjust the changing of the CRC value?
Good luck!

 

I used both files,but it's have an error.

First :dump rom










Second :Integrate the Version1 or Version2's file(F7731B4C-58A2-4DF4-8980-5645D39ECE58.ff) into the BIOS.But here's error.


PS:The default BIOS is in 359#

 

I tried it also with Andy's tool version 1.90 and got same error message.
As the length of the F7731B4C-58A2-4DF4-8980-5645D39ECE58.ff was not changed, the error must be in Andy's tool.
You can try to post this bad behavior at Andy's thread for his tool at my digital life forum.

 

Here is my modified BIOS(patched all things).

After flash nothing changed.EIST still locked.

Hi ryuila,

Sorry for replying late. Because you already tried the modified BIOS I sent to you & EIST still locked, I'll take a look again into Y450 BIOS later. Please give me a couple of days because I'm still in vacation mode. Just want to let you know, your & maximinimaus mods are correct & exactly the same with what I did. Please PM me the procedure & tool you use to flash the BIOS. I want to make sure you didn't mistakenly flash the original BIOS instead.

 

Hi,

I found another EIST lock bit in BIOSCOD04.ROM module. Sorry, I didn't check other modules earlier.

BIOSCOD04.ROM:-

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D00001000      or eax,0x100000
0000076C  0F30              wrmsr

Modified BIOS:
( Use at your own risk!)

Hey Guys,

I've got a M1330, with a X9000, it was running fine up to about a few days ago, when i decided to check out the bios, and make it run on stock multipliers. I re-enabled EIST and IDA, and start up the system, i get a BSOD!
I disabled EIST and kept IDA enabled, boots up fine, but the multi is at 6X, which isnt that great...

I figured id try again, and still get a BSOD when EIST is enabled. Does anyone know how to make EIST work without throttlestop?

I know the BSODs are from the voltage and frequency constantly changing, and it more than likely hit a low voltage with a high frequency, causing it to BSOD.

I would just like the system to work at the normal clock speed. Your help is greatly appreciated.

 

The X9000 does not support IDA.
With ThrottleStop you can set the Multiplier and the VID for extreme Intel CPUs like the X9000.
To run the system normally just switch the laptop off, turn it on again and don't start ThrottleStop.

 

I tried that, doesnt help though i still get a BSOD.
I have also tried disabling IDA, and keeping EIST enabled. But it does not help. Also tried, a power drain, removed battery, unplugged bios battery. Still get a BSOD when EIST is enabled. I want EIST enabled, to keep the multi at 14X which is basically the normal multi of the CPU.

 

Where do you enable/disable IDA and EIST? As I already said, the X9000 does not support IDA.
Is the BIOS modded?
Please post a picture of your ThrottleStop settings it.
How do you start ThrottleStop? Automatic at system boot ore manually?

 

The Bios.

I do realize that.

No.

I allow to start on startup automatically, so i get the stock clocks, being 2.8GHz.


BTW, the whole point, is having it start using EIST, and NOT using throttlestop on startup.
I WASNT trying to enable IDA, lol

TS is working fine with the CPU, check below benchmarks

how to modify?
i had found those code,but how to modify it?
the bios i can't download...

 

This already explained in the Example Guide.

Anyway, I have uploaded the modified BIOS at sendspace. Please go to post #374.

 

@TheCodeBreaker
Judging from your CPU-Z screenie, you pushed the CPU too hard.
If you want to run your system at the highest multiplier 14 you don't need TS, the High Performance powerplan does this also.
I suggest following, deactivate TS start in system start.
If you want to overclock your X9000 find a stable Multiplier and VID.

 

YES！！It's worked!!Thank you!
But,could you tell me how to modify the bios?
I don't understand your example..

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D00001000      or eax,0x100000
0000076C  0F30              wrmsr

Modify to

Code:

0000075E  66B9A00???      mov ecx,???
00000764  0F32              rdmsr
00000766  660D0000???      or eax,0x????
0000076C  0F30              wrmsr

 

This:-

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D[COLOR="Red"]00001000[/COLOR]      or eax,0x[COLOR="Red"]100000[/COLOR]
0000076C  0F30              wrmsr

0x100000 = 100000000000000000000b
bit    31 30 29 28 27 26 25 24 23 22 21 [COLOR="Red"]20[/COLOR] 19 18 17 16 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00

or eax,0x100000 = set MSR 1A0h bit 20 (EIST Lock bit) to 1

Change to:-

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D[COLOR="Red"]00000000[/COLOR]      or eax,0x[COLOR="Red"]0[/COLOR]
0000076C  0F30              wrmsr

 

I dumped your bios,and contrast your BIOSCOD04.ROM and default.
default code:

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D00001000      or eax,0x100000
0000076C  0F30              wrmsr

your code

Code:

0000075E  66B9A0010000      mov ecx,0x1a0
00000764  0F32              rdmsr
00000766  660D0000[COLOR="Red"]0[/COLOR]000      or eax,0x[COLOR="red"]0[/COLOR]00000
0000076C  0F30              wrmsr

is that right?

ps:your file(BIOSCOD04.ROM) i can't open with ETU-DASM...

 

a ha!i guess is right,thanks alot!!

 

do you have to do this at every boot up or just once and it will be permanently?

thanks

 

Model: Acer Aspire 4930G
CPU: T9400 (9.5x, 2.53GHz)
BIOS: Insyde 1.20

I followed the steps in the guide, flashed the bios successfully.
When there is no load, ThrottleStop reports ~10x (good)
However, when I start orthos, it drops to 9.5x instantly (not good)

So, my question is: Did I make some mistake?
When unlocking ida, I expect the FID to be 10, but the result is not satisfying

p.s. I also tried with RMClock, same result.

 

EIST needs to be disabled for Dual IDA to work correctly.
Your two screen shots show that EIST is checked.

 

argh... I do no get it! Did I misunderstand this post?

 

Has anyone modded a Gateway P-6831 Bios for EIST by any chance? I'd take any version that has this enabled. My hex programming skills are atrocious, but I'd love to see this old PC get some more oomph from the T9300.

 

I attempted this for my Asus G50vt x5, but I didnt get very far because its not running a pheonix bios. I remember editing an older asus f3sv bios using the proper tools but it would require some research to get all the software again. Im wondering if I were able to extract the bios, would the trigger for EIST be similar or completely different in a non-pheonix bios???

Any help would be appriciated, just put in a t9900 and I cant seem to bring my FSB up as high as I did with my old CPU...so I gotta increase the multiplier =/

no eist option in bios

 

I have this laptop as well and if it were possible to disable EIST in the bios, then I'd use throttlestop to enable IDA .. so that the CPU voltage of my P8700 would go from 1.163v to 1.25v so I could hopefully overclock further.

Good luck but I think my upgrade will be to a x9100 so I can ramp up the multiplier and Vcore.

 

whoa, hold on a min...

enabling IDA does actually increase the voltage? someone mentioned this in another post but they werent very certain. Hmmmm interesting.

Im just apprehensive about changing bits in my bios, not sure if Asus has a blind recovery method. Anyone out there familiar with Asus bios? If not, guess I gotta be the pioneer.

Ill try to return with updates if I dont brick this thing! heh

 

Hi Unclewebb (& everybody)

since I don't like glossy screens I've "thrown away" my Asus N73 and now I'm the (not fully) happy owner of a Dell Latitude E6500 with a Core 2 Duo P9500 inside.

experiencing strange little lagging when closing windows (not the OS, which by the way is Win 7) I've been looking around for a solution. (actually there’s no window lagging when Aero is deactivated...)
I read about throttling issues on Dell laptops…

anyway I found these posts talking about this unique program : TS
so I installed it on my Dell and here's what I did :
1. Untick SpeedStep in BIOS
2. Set Processor power management to be 100% all the time
3. Start ThrottleStop
4. Saw that both multipliers were 6, that EIST wasn’t greyed out, and that voltage was 1.0000 in both fields
5. Put 9.5 as multiplier
6. Put 0.9500 in the voltage right field
7. Tick “set multiplier”
8. Turn on
9. Tick EIST
10. Saw multipliers going immediately 9.5
11. Saw voltage remaining 1.0000 in the left field / 0.9500 in the right one : why ? (notice that CPU-Z reported 1.0000)
12. Untick EIST
13. Saw everything remaining ok
14. Thank you Unclewebb

but unfortunately my poor Aero windows ke-e-e-ep on lagging when I click “close” or even “reduce in taskbar”…
Today I spent hours reading this post (until page 17).
I’ve tried right-click method to enable dual IDA -> BSOD
I’ve tried 10 as multiplier (the maximum) -> BSOD with any voltage

Finally I repeated point 3 to 13 with 9.5 as multiplier

And there came the weird thing, when I :
1. ticked EIST again
2. turned off
3. unticked EIST
4. saw both multiplier suddenly jumping to 10 (which is the normal IDA multiplier according to this) and locking there
5. Saw voltage in the left field stuck to 1.2250 (while 0.9500 in the right field)
please see attachment
Well I don’t know why I did this way but now it’s done, it’s pretty good, and I’d like to keep this state on my Dell
So I would be happy to hear some explanations about what did happen, and maybe some tricks to keep (or resume) this dual IDA state after I shut the power down

Thanks

 

Hello! kizwan:

First, Thank you very much for your brilliant "EIST Unlocked Example Rev 1.1a.pdf" on How to Enable Intel Dynamic Acceleration (IDA) on Both Cores of a Core 2 Duo.

I have a Levovo notebook F31 with chipset PM965, and I've tried to make DUAL-IDA work on it for several months. It has Phoenix BIOS.

I have carefully studied your Example already. I have tried to modify the BIOS and followed every step as you described, I have even checked all BIOS modules, but only find two patterns as your Example described in MOD_5100.ROM. After I modify them and update the modified BIOS, the EIST function is still locked down by BIOS, and EIST is greyed out in ThrottleStop software. I have even tried different CPUs, but always failed.

I have read most of the post in "http://forum.notebookreview.com/windows-os-software/477704-how-enable-intel-dynamic-acceleration-ida-both-cores-core-2-duo-26.html", but I'm still confused about my problem.

If possible, could you please help me solve the problem and tell me how to modify my BIOS? Thank you very very much in advance! I'll be looking forward to hearing from you.

This is my original BIOS：

Hi hyg,

Please give me the modified BIOS too. Thank you.

EDIT: I found three places where EIST lock bit is set.

Spoiler

Code:

MOD_5100.DASM
000040D2  B9A0010000        mov ecx,0x1a0
000040D7  0F32              rdmsr
000040D9  0D00001000        or eax,0x100000
000040DE  0F30              wrmsr

00004CAC  B9A0010000        mov ecx,0x1a0
00004CB1  0F32              rdmsr
00004CB3  0D00001000        or eax,0x100000
00004CB8  0F30              wrmsr

ROMEXEC00.16.DASM
000004E9  66B9A0010000      mov ecx,0x1a0
000004EF  0F32              rdmsr
000004F1  660D00001100      or eax,0x110000
000004F7  0F30              wrmsr

*For (ROMEXEC00) change " or eax,0x110000" to " or eax,0x10000"

 

OK. Thank you very much for your quick reply. Please wait a moment.

Thank you.

 

Please see my previous post. I found three places where EIST lock bit is set.

 

Hi! kizwan:

You mean another EIST lock bit is in BIOSCOD0X.ROM? But I can't find it. I only find two places in MOD_5100.ROM. could you please tell me which module is another EIST lock bit in ? Thank you!

PS:This is the modified BIOS:
