Hi there!
This is also in the AMI Bios mod as I would also like Overclock functionality to my mainboard but putting it here as well so CPU experts can maybe advise.
I am a newbie to BIOS modding so I have no idea if this is even possible or not...
It would be brilliant if my IMISR-VM board could operate a Core 2 Quad Q9100 - it is a PGA478 chip so it might work??
From what I understand is if the BIOS doesn't have the microcode for the CPU then it won't work... So is there a way to program the Penryn Quad-Core processor microcode into my mainboard?
What tools can I use to maybe mod my own BIOS as I'm keen to get into this sort of thing...

Thanks in advance!

(Bios upgrade file attached)
Post screenshots of first (CPU) & third (Mainboard) tabs of CPU-Z with current CPU.

Thanks for getting back to me so quickly!
Here is the CPU-Z output...
(BTW it is OC'ed using FSB increaser)
Thanks

Your laptop is based on GM965 chipset. It support maximum FSB=800Mhz.
Attached BIOS (version 0117) has support for Penryn core. So T8100, T8300, T9300 & T9500 are recommended for upgrade.

A few motherboards with Socket P (even with PM45 chipset) can boot quad cores CPUs. It's hardware incompatibility.
But you can try the motherboard's mod for quad core CPU supporting:

Hi!
That's brilliant news then!
"Maximum FSB=800Mhz" that's weird though because how did I get my FSB to 1041Mhz using setfsb? Is it fake increase or something because benchmarks show a big difference and is noticeably faster. Also will it support Core 2 Quad processors as well with my FSB increase tool to 1066MHz??
Mobo cannot overvolt with current BIOS so is a bit unstable at 1066Mhz FSB (Blue screen) presumably down to voltage deficiency?? (I don't know so sorry for dumb questions! Confused Huh ). 
Also it is not a laptop, but a rather odd desktop mini ITX mobo from an RM Ecoquiet 965!  Big Grin

Should I upgrade to T9500 or try to mod my bios to try and get a 1066mhz processor in???

Thanks

You can try BSEL mod 1066->800 for CPU with FSB=1066Mhz and overclock FSB.
Hi!
Thanks for getting back so quickly - respect!
Is the BSEL mod where you jump the pins on the bottom right corner?
But how would I know if there is core 2 quad microcode in the bios? Or unless you know that already...
(edit= saw your edit about hardware incompatibility..)
Many thanks

Quad cores & dual cores CPU use the same microcode. But your motherboard doesn't support quad cores CPUs.
About BSEL mod 1066->800 you can read there - https://www.bios-mods.com/forum/Thread-R...#pid113800
Hi!
Ok, so I am getting Core 2 Quad Q9100 much cheaper than T9900. If I wanted to go down that route where would I get the modified APIC table for my mainboard (unless the one in your link will work for mine and is like a universal thing.)
So as per my understanding after viewing the thread on quad core CPU on dual core mainboard, if I do BSEL then there is no need for the soldering thing in step one, but I will still need to insulate the pins specified, load the custom apic table and quad core is running??
Thanks for your patience! I don't really know and I don't want to mess things up.
(edit = I did not see your original edit, had reply window open while reading guide)
Many thanks

BSEL mod doesn't replace Core 2 Quad mod.
