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

[unclewebb]

In ThrottleStop 2.89, I had to manually uncheck 'Power Saver' & 'Disable Turbo' though.

I think TS 2.99 does this automatically for you now.

I also have a D830 with a T8100 and it's happy with 1.05 V in Dual IDA too.

I'm just the programmer.

meh, just the programmer.

As for fulltime IDA it was just an accident waiting to happen and besides yourself there was only one other person who showed any interest in it over the course of ~3 months and that was for a quad with DDA (Dual Dynamic Acceleration). As far as I know he got it working but disappeared so quickly I couldn't get any feedback about it. I think if it wasn't for your commitment to providing great software then probably DualIDA would be little known about today so really you deserve all the credit and appreciation for doing that.

Regarding veloscaper's CPU, I can not see any problems with the CPU registers or why it should not work with TS. The only thing I could think that might be different from TS and the program I gave him to test is forcing idle states so possibly it could be the higher idle states are not used by the OS and hence no IDA. Other than that idk.

Hi guys,

I detected some issues with Phoenix BIOS when trying to rebuild the BIOS image (for dual-IDA mod). Please visit post #256 for more information.

Hi,

I like to thanks to kizwan for his great tutorial
Well i managed to unlock EIST on my HP Dv9684(Chipset 965).
Im using the F59A bios, its used in a lot of other Hp's.
Its working 100% fine here!

Original Bios:

WinFlash for HP Notebook System BIOS (for Notebooks with Intel Processors) HP Pavilion dv9684eg Notebook PC - HP Customer Care (United States - English)

Modded Bios (Wifi Whitelist, Slic2.1 and EIST):

Use at your own risk!

How can i use this modded bios file. I have same laptop and bios, i think it will work on my laptop to.

Nevermind, i figured it out and is working now.

Thanks to everyone

FWIW, my 8530p w/ P9600 cpu is working in dual IDA mode with TS. Not sure why but it just started to work today.

hi guys has anyone with p8400 on hp dv5 has successfully modded bios to enable IDA on both cores as currently EIST is grayed out in mine?
thanks.

dualIDA bios for the DV5 doesn't exist as yet. You could be the first to mod the DV5 bios. Just follow kizwan's excellent instructions here.

^i will look into it,thanks by the way however i have heard that enabling slfm cuts the frequency in half but in my case both cpuz and throttlestop are showing 266 x 8.5 so have i understood something wrong?

farsang: If you are using ThrottleStop to control your CPU, you will need to use the Power Saver feature and have SLFM checked before you will see the bus speed get cut in half.

If you are using Windows to control your CPU, you need to make sure the Control Panel - Power Options - Minimum processor state is set to a low number like 5% to give your CPU a chance to idle down and go into SLFM mode. If you want ThrottleStop to be in control then set this to 100%.
