Processor does not support cmpxchG16b

[dog-man]

I have an Intel Q9650 core 3ghz overclocked to 4.5ghz quad processor.

I have been running windows 8 64 bit since it was available as an upgrade from windows 7 64 bit.

I am unable to download and upgrade to windows 8.1 as I get a message saying that my processor does not support cmpxchG16b.
I have run Coreinfo and that confirms this.

However, someone who has the exact same processor as me has run Coreinfo and his reports that his processor does support cmpxchG16b.

So, could it be a motherboard issue? Do I have to alter something in the bios to enable support for this?

My mobo is an Abit IP35 Pro XE.

I would be grateful for any advice.

I have the last official bios that Abit released before they decided not to make motherboards or support the ones that were sold.

Perhaps there is an unofficial one out there that could help me but I am struggling to find it if it exists.

Can you confirm if your board is the same as mine?
IP35 Pro XE, as I am sure you know there are others with similar names.

Any idea where I can get an updated bios as that is probably my problem?

My bios is: W627DHG-6A790A10C-11 dated 05/26/2008.

As far as I am aware that is the latest official version.

Yes please.
I would like to upgrade from windows 8 to 8.1 if at all possible.

Just need to find the flasher program now although I might have that on a very old hard drive somewhere under a pile of dust.

Thanks for this. I will let you know how I get on when I find the time to do it.

Upgrade completed and everything seems to be ok.

Have overclocked again.

Have run Coreinfo and it now shows as supporting cmpxchG16b, so I should now be able to upgrade to windows 8.1.

Thank you for your help!

 

[dog-man]

Just confirming that I am now being offered the 8.1 upgrade.

Run it all the time.
Its always been very stable, never had any problems.
