Hello everybody, I owns an Asrock 775 DUAL-VSTA, I would like to know if there is a vcore voltage mod. I've tried the Shamino's LGA pin mod, but like other people, one core of my Pentium D 930 goes off with this mod.
This board undervolts very bad, my CPU is 1,3V at default, and the board gives only 1,2V at load .

I guess it's the same board as of v2.10 of the 775dual-vsta-bios, the quadcore is supported...
4CoreDual-VSTA & 775Dual-VSTA difference.
This below quote is from a someone with inside connections to Asrock.
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.

well i read yesterday on the conroe xfire board they connect the sgnd and the vid4 to offset the vcore on the cpu. u can also use vid 1-4 to make diff voltages. im not to sure if it works but it works on that board. i will try to find the thread i read this at. heres a pic of the mod they do on the l6711 ic but we have a l6714 ic. so plz do not do this mod yet i will do more research on it and i WILL COME UP WITH A VCORE MOD FOR THIS BOARD THAT USES A TRIMMER TO ADJUST VOLTAGES. ttyl
edit: i found the page the mods on here u guys go. remember i dont no if this will work im just tryin to get us a vcore mod done by a trimmer so we dont have to mod r cpus and beable to adjust the voltage wit a trimmer. My new Asrock Dual SATA2 Vcore mod. (56K warn)

ok i think i found were we need to mod to change vcore we just have to figure out wut exaclty to do. so someone who knows alot and i mean alot about reading this stuff needs to help us out here. take a look at the bottom right in the pic. it shows to lines going out and its labeled VCORE. now if im right this will allow us more vcore. it also says this is a positive offset meaning if we adjust it it will raise the vcore. it says it can be raised with a resitor(trimmer) from sgnd connected to offset witch we could solder a trimmer between the pin OFFSET(number 32) and sgnd(number 19) witch would allow positive voltage offset therefore raising the vcore. i would like someone to read all that ive typed and tell me wut ya think. this also might set off the ovp(over-volt protection) and would possibly beable to connect a trimmer to the ovp pin(number 33) to ground so we can raise the resistance allowed through the ovp therefore let us up the vcore without tripping the ovp on the board. if im right about putting a trimmer or resistor from ovp to ground. well i hope this makes sense since im new to all this and if im wrong about sumthing plz let me no so i can understand wuts wrong so i can learn the right way of things.ttyl
Hi everyone. I just bought a 775dual with an Intel 6300. First thing I did was apply the Vagp mod. I noticed my resistance was 1.98K which was about 0.1k higher than what you guys have. You guys dropped it to 1.8k so -0.1k down to 1.7k. Now instead of dropping it to 1.7 I dropped it to 1.8 since mine came with a higher resistance. As for overclocking it doesn't seem to have gone well. With the suggested settings my setup freezes at boot at 310mhz fsb. I figure that if it freezes at 310, that means I'll probably have errors at 305 so I might aswell keep it at the board's regular max which is 300 which is perfectly stable. After owning a piece of **** ECS motherboard for 5 years it taught me a lot. Don't bother wasting your time getting those few extra mhz, spend it on something worthwhile. 300 or 310...no biggie so I'm happy.
Besides the overclocking aspect I'm really surprised by the board, it's very high quality and works perfectly. The bios has a ton of options, except for voltage mods. I like the idea that the memory works independantly from the fsb. If the memory runs at 166mhz and I overclock the cpu it's still 166mhz for the memory, nice. Super board, lots of options except for hardcore overclocking...I'm happy with mobo.
I've just found a vcore mod that works on the Asrock ConRoeXFire-eSATA2. It seems that the Asrock 775DUAL-VSTA has the same chip (I'm not 100% sure). Someone could look here and tell if it is possible to do safely on our Asrock 775DUAL-VSTA??.
the conroexfire has l6711 and the 775dual vsta has l6714 chip so they are different. the pins are also different pattern on the ics. i will post a vcore mod as soon as i get my board cuz i think i figured it out. ttyl

Thats not true sadly, but if you want that kinda of features, you would need to by a nvidia 6 series mobo.
My own little table of dividers
ddr400 - 200mhz = 4:3
ddr333 - 166mhz = 8:5
ddr266 - 133mhz = 2:1
so if your fsb is 300mhz and your divider is 166mhz = 8:5 your memory is running 187,5mhz - ddr375
yesterday i bought a-data ddr2 667 ram (2x512)
i cant set fsb more than 285mhz -- prime errors over 287mhz.
Flexibility disabled, vlink and ide strength set ti highest, spread spectrum enabled, vagp - auto and vram also auto.
setting vagp and vram nothing do for me.
memory ratio is 1,25 to fsb = 357mhz(713mhz effective).
default timings.
i can set fsb at 300mhz when i set flexibility enabled but then
my memory will be set to 225/450 mhz (ratio 0,75) - very
low performance.
I would to set 295mhz only, which my previous ddr400 i didnt have any troubles on 295mhz.

any ideas and solutions
(sorry for my english)
hi
do the pencil mods
with Vagp=1.71 and Vnb=1.51 , overclock PCIeSync option ( if your graphic card is agp ) , PCI=34.78 , flexibility enabled , you can reach fsb330/memory247 stable , or fsb300/300 with flexibility disabled , i think it's the max you can expect with ddr2 ( ddr works better with this card)
.
Linear Mode
