new microcode update to support the new processor stepping

HP Recommended
HP xw4400 Base Model Workstation
Microsoft Windows 10 (64-bit)

Hello,

Can someone please help to find a new microcode update to support the new processor stepping? 

I did an upgrade to my processor from core 2 duo E6400 to a core 2 quad Q6600.

When I start the computer, I get the message:

"error 1801 - you need a new microcode update to support the new processor stepping".

I press the option to boot anyway, and after windows start, I found out that Windows 10 recognized the processor with the speed of 2400 MHz, but only with 2 core, not 4. (like the old one).

I installed the latest bios update that was on HP support site, but wasn't enough. The bios update was form 2010, and the processor is from 2007, that's way I was expected to be ok, but it wasn't. 🙂

Thank you in advance for your help

Hi:

 

There is only that one BIOS update and no separate microcode updates for your PC.

 

Below is the link to the xw4400 quickspecs. 

 

The supported processors can be found on page 3.

Only the QX6700 processor is supported.

Thank you for answer. 

Unfortunately, I didn't find other processor to buy, so I have this one...

I solved the error with one microcode from bio-mods site, but windows still see only 2 cores, not 4.

I hope to find a solution... 🙂 I don't Know if it is necessary to reinstall windows

You're very welcome.

 

If you don't find an answer, you can buy the QX6700 on eBay.

 

This seller on eBay ships to Romania.

I solved the situation with the microcode from the above site mentioned. (bios-mod. Com....) 

 

After, the microcode install, I modified în msconfig to let Windows to see core number. Restart, and now I have quad Q6600

 

All the Best 🙂
