Asrock 775Dual-VSTA Volt Mods

[Digz]

Google came up with loads of stuff but i'm still none the wiser.

This was taken from a link about the Xeon

Systems with Echo TPR Disable (R/W) bit (bit [23] of IA32_MISC_ENABLE register) set to '0' (default), where xTPR messages are being transmitted on the system bus to the processor, may experience a system hang during voltage transitions caused by the power management events.

Implication:
This may cause a system hang during voltage transitions of power
management events.

Workaround:
It is possible for the BIOS to contain a workaround for this erratum. The BIOS workaround disables the Echo TPR updates on affected steppings.

Thanks to Jimmor and Victor89 for posting links to the modded bios.

New modded 2.6A Bios works great according to user.

Mmmm, nice to see Speedstep and No-Execution options back again :>

Well, but is there tehnicly possible to add, for example. Logos and such a things in Boot-up fhaze, laike it is in ASUS mobos. There is some Video-card Logos, eitch could bee added in mobos startup, but there is no options to do that :>

Antway modded BIOS works fine, only users should Power-off mobo and then turn it on again, no just oress "Restart" button.

Any extra volt settings in the modded bios ?

I don’t think so, I’m not using it myself as I do not need it.

I'd like to try the volt mod but i now have a D 945 instead of a D 805 and the couple of people that i've read that tried it on the 9x chips ended up with only one core working.

These guys have solved that problem with their mods, read thread & ask questions.

Let us know how it goes with the mod?

SLI on 775Dual-VSTA???? Maybe LOL!


SLI using AGP and PCI-e cards simultaneously is possible on a similar board.

Can we have someone try this on this Mobo?

Do the cards need to be marked as SLI ?

Looking thru the cards in the below link I see no SLI markings on them.

finally got an E4300 to drop in my board.

Unmodded i'm pulling 300fsb so far. 2x512 OCZ PC4800 TCC5 @ 2.5-4-3-8-1T 2.6v 300mhz.

305 might go but 310+ just locks at POST.

EDIT
Member (ProStock) in another forum got 320FSB with volt mods and using the below bios settings.

[STEvil]

Nobody's touched GTL yet?

[Alchemist]

GTL=Auto

Do you think that there are gains to be made with the GTL settings?

[STEvil]

It is what makes or breaks the fsb of a quad, why not?

Not exactly "no mods", since ProStock's posting actually shows Vagp has been increased (presumably by pencilling mod) to 1.8v !

[Alchemist]

My Apologies I have misquoted the original post by stating that is was with no mods.

My Real Bad?

I have edited post accordingly.

[jimmor]

Appears that the max overclock for 4CoreDual-VSTA has just been raised a bit more,

I'm very happy!!!!! :

V-Core : 1.564V
V-AGP : 2.120V
VTT : 1.500V
PCI EX : 126 Mhz or 117 (is good too)

I have my old Asrock 775Dual-Vsta motherboard I'm tempted to try with an E4400. It won't overclock with messing up the pcie/sata frequencies. But if I ran the E4400 at 2.66, then I suspect that the pcie/sata frequencies would be normal, instead of overclock shifted. Since the memory dividers change at 240fsb, perhaps at 2.66 everything'd be normal even if the chip was overclocked. Any thoughts?

[Alchemist]

Sad Sad Day

Asrock has just killed the 4CoreDual-VSTA and replaced it with 4CoreDX90-VSTA.

DDR only single channel memory I think PCI-e only.

No AGP slot ........................Sob Sob.

[ibby]

DOes any one have information on the modded BIOS's?
thanks

[Johnny Bravo]

Vcore mod




100kohm between these two points. Lower resistance -> higher voltage

Really looking forward to playing with this board, upgraded to BIOS v 2.70 from shipped one and have now have control over my x6800 unlocked multiplier!!

[Johnny Bravo]

I've cleaned up the others for reference - hope you don't mind -

[Alchemist]

Nice work dude.
