All I can say is that you can try the 1.6 Pin Volt mod and if it does not improve your volt stability issues, just scrap off the silver varnish (with a knife or needle) and your back to where you were before.Quote:

2.20 bios is out now i like it better than others
Any vcore mods? NOT THE PIN MOD, I tried that mod and it didn't work, one core is disabled after that mod. I'm looking for a mod for the motherboard to increase the vcore. Thanks.
I would like to know if there is a vdimm mod that consist in connecting the 3,3V line of the PSU directly to the RAM with only a wire.
I've done this mod before on other motherboards but I don't know if it will work on the ASrock 775DUAL VSTA.
Sorry for my english :slapass:
It seems like this board can hit 325-335fsb with all the mods. I'm about to order a E6600 for this board, just a few questions. How do I measure the resistence after shading the Vnb and Vagp resisters? Do I touch one lead (from the multi-meter) to the resister the other to the case or one lead to each "leg" of the resister? Does the power needs to be on to check it? Also, did anyone tried Verdeva's pencil vdimm mod? Cuz I don't want to solder if possible.
It seems like Oliver2000 over at VR Zone is having the most success with this board, did anyone else duplicated his settings? (Plus PCI-E 120, AGP 1.94, and NB 1.58) Did you get the same results? If so, what resistence did you use to get to those voltage (for AGP and NB)? Sorry for all the questions, I don't want to fry my mobo when I start modding. Thanks.
@Alchemist
Are both of your cores running the same as before the pin mod ?
and have you had the 805 underload for long lengths of time as
i'm concerned about the mosfet/volt regs overheating.
well i've had the 805d/775dualvsta combo for about two months now. With stock Vcore I only got the cpu up to 3140...kinda weak, but I ran it hard for two months and had no problems. After putting off my pin volt mod for too long, I broke out my conductive ink and electrical tape today, very exciting. Unfortunately that wore off quickly as I'm only able to get a 163 FSB overclock (3260) with the 1.5volt mod!!! Absolutely Ridiculous! Bios, & CPU-Z show 1.48-1.5 volts consistently so I know my mod was done correctly (not that I needed that to tell me, I tested my connection with a multimeter and it's nowhere close to touching another pin landing). This absolutely infuriates me and I'm about to piss my wife off and buy a conroe. Any ideas? Alchemist I'll call you out, I've seen you're results here and on other forums as well with this combo!

What are the regular Voltage options in BIOS?
I remmebr it being low med and high I think... what are the values?
if u knew more about the board u would no theres no vcore adjustments only agp and ddr. no to be rude or anything. i got my p4 511 2.8ghz on stock volts to bench at 3.9ghz so i think its pretty good. i will try volt mod when my board gets here. first time i had a 1.6 bios chip with a 880 pro/ultra chipset and could hit 3.8ghz benching, it burnt up cuz of stupidity by me lol so i rma it back to newegg. got 2nd board and it came with 1.7 bios chip and a 880 pro chipset and i could bench at 3.9ghz, but the agp slot burnt out of this one dont have a clue y i could run orthos on ram and cpu as long as i wanted with no problems. as soon as i did sumthing 3d related or anything thats using the videocard it locks up so agp slot is defective cuz i tried 2 cards that work great in my other computer. so it went off to newegg today and gonna be waitin for a new one again and i hope its the last time. o ya 3.9ghz with my cpu is 186 fsb and was stable as can be.
When I did the last pin mod fromto1.5 to 1.6volts, the VRM's and mosfets became very warm and there was a burn smell for awhile, but I kept good ventilation around those areas and have had no problems. You may want to consider a dedicated case fan for this area.Quote:

I did all the mods accept the 1.55 volt mod, this gradual burn in perhaps helped the board.
I would not recommend a volt mod from stock to 1.6volts straight away, gradual volt modding is probably safer due to the gradual burn-in process.
Both cores are functional.
I play games for hours with a pc load of 50 t0 60% and CPU gets up to 74° with water cooling.
You will need water cooling to run at above 3800MHz in my opinion.
:)
Thanks for the info :)
I can only put it down to maybe a different CPU stepping.Quote:

I have a 750W psu maybe that’s keeping the voltage more stable, but honestly if your ram is set loose in the bios and other bios settings are correct then I have no answers.
Sorry to hear that.
:(

No mods done, yet, and went from 285fsb to 300fsb stable whit bios 2.10 from 1.90 whit DDR2 at 1:1 -same result whit bios 2.20.
bios 1.90 and DDR1 was stable at fsb 300, so the chipset dont like the higher mem freq.
Good results dude!Quote:

Is this truly a new model or just a box name change for the 775Dual-VSTA?

That sucks
As i have only just bought my board and i have not fitted it yet
and a new version is out.
4CoreDual-VSTA & 775Dual-VSTA difference.Quote:

The main difference is that the 775Dual-vsta uses Pt880pro which is not suppose to run 1066FSB processors. 775Dual-vsta can run that is due to overclocking.
The 4CoreDual-VSTA uses the newer PT880Ultra which is certified to support the 1066FSB processor.
You can check http://www.via.com.tw/en/products/chipsets/#
To see the difference between PT880Pro and PT880Ultra.

Isn't the QX6700(B3) Kentsfield a quad core chip ?
http://www.asrock.com/support/CPU_Su...l=775Dual-VSTA
two thirds of the way down since bios 210.
Yes it is a quad core and your right the dual vsta does supports it but this new board might have a better overclocking north bridge.Quote:

I don't think that there will be an ASRock 4CoreDual-VSTA board for a few moths outside china.
I can't wait for a complete review on it.
;)
Would be nice if i could at least get a few months out of the dual board.
:)
Hello, I'm searching for a vcore voltage mod, to overclock more my Pentium D 930. At full load the Asrock only gives 1,2V to the processor, where the nominal voltage is 1,3V.
I would appreciate any kind of help. Sorry for my bad level of english.
I see that you have been looking for this mod for awhile at VR Zone, I don't know any motherboard CPU volt mod for this mobo.
Sorry.
