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.

Hi everyone!
I have a 4coredual-vsta since 4 years ago, and I never have been able to make this board stable with a q6600 G0.

I use It with 2 Kingston KVR800D2N6/2G and last stock BIOS 2.39.

I know FSB must be 5% lower than stock, but I'm having instability even at 240-245mhz FSB. Also I tried manual RAM timings and 533 mhz but no changes.

Can It be a cap related issue or is just bad settings?

Probably bad caps
Q6600 power draw won’t help

Try memtest.
Leave it running overnight.

A couple years ago I got a bunch of SD and DDR1 and about half the SD I tested was developing bad bits or dead.
I couldn't test the DDR1 at the time, but given the age difference, it couldn't be far behind. DDR2 will be next.

Same here, my 4CoreDual-VSTA is unstable with a Q6600 when it reaches 100% CPU usage. I've tried different RAM, power supplies, hard drives, the latest BIOS, and various FSB underclocking settings, but nothing solves the issue. This problem doesn’t occur when I use Core 2 Duo CPUs.

VRM was shit even brand new. And caps are showing their age.

The only thing I can say about unstable Q6600 is either dropping CPU multiplier below x9 (so x8 or x7) and if that doesn't help, dropping one memory channel and/or trying higher AGP voltage (which is the same voltage that goes into northbridge/chipset).
Flexibility option might work, but at that point - dropping a channel isn't much different (you just retain RAM capacity).

Lastly, as unlikely as it is, a CPU VID mod might help if it's vDroop related issue (+0.1V to base CPU Voltage should help in that case - BUT it WILL increase the load on all VRM section components aside from CPU temperature).
