Regardless if it works or not, You will be limited to ~2.6GHz clock on it max. (due to FSB limitations on Quad Cores).

Has anyone successfully tested the Xeon X5470 on the board?

Xeon works in both boards with FSB limitations.
No real advantage in using them.

Hello,

I have just received a 775Dual-VSTA in very good condition, my goal is to make a Win98SE+WinXP build for fun.

I have updated the BIOS to 3.19a beta, upgraded CPU to Pentium E5800 3.2Ghz 2MB and 2x2GB DDR2 667Mhz.

First I tried to install Win98SE retail, with 256MB RAM installed and the VIA SATA in "non-RAID" mode. I was able to create a partition of 4GB, format it and start Windows install. Everything went well until after I entered the CDKey, when it search and install the devices. I have a blue screen saying that it can't write to C:, so I restarted the installation on another HDD but same result.

What should I do? Do I need to apply Rloew SATA patch before this step?

Thanks

Check your ram. Sounds like memory error to me.

Also make 9x installation with around 512MB RAM as it doesn't handle much more and after you apply the patch put your 2x2GB modules again.

Edit: ahhh it seems I missed that at your post. Nevermind.
It seems RAM related to me too.

Hello all, i am getting a 775dual-vsta motherboard, and i plan on using a core2quad Q9300 in it.

I understand i will have to upgrade the original bios. And i know the clocks will be decreased because the cpu has a 1333 mhz bus, but the motherboard can only deliver 1066.

The question is: will be the 3.19a BIOS enough to operate this CPU, or i will have to mod the BIOS with a microcode for this chip?
If i have to mod it, which microcode is the one i need? The Q9300 is Revision M1. (i dont know if i need the 10677 or 10676 - plat10, plat 91, plat44, very confusing)

It will be fine. No mod.

Thankyou for your feedback. I was just asking because previously someone mentioned having trouble with 45nm quadcores, but havent mentioned what bios he used.

I am confirming the 775Dual-VSTA is capable to work with the Q9300 with the latest beta bios.
