vcore mod ASRock 775Twins-HDTV

[fras]

Post some super pi scores with it so we can compare how fast chipset is. 310 FSB won't be so bad with x9 multiplier on e4300.

[|Rave|]

The board is ASRock 775Twins HDTV 2.0



it isnt stable at this setting, maybe coz of the DDR ram that am using? in anycase, i think increasing the NB voltage would help here, if anyone is willing to help me out with this, can provide high res photos of the board...

32 sec super pi is very slow. 2,4 GHz conroe on 975x has 20 sec super pi. Do you have programs activated while starting super pi proces?

Memory single, only 225MHz Cl 2.5 and win xp not with luna

My asrock was rock solid @ 340FSB ORTHOS torture stable using my DDR2 as per sig, all I want is 400FSB

Alphaone, do you have ASRock 775Twins HDTV 2.0 and if you do, could you post superpi 1MB score, since i want to see how much slower chipset is from intel's. I'm looking for cheapest posible way to switch to conroe , and this board seems to be an answer

has anyone got the vcore mod to work on the revision 2.0 yet? i cant get my 805 over 3.2ghz the power drops down to 1.15v under load i know this chip and motherboard can do a lot more with more voltage i would be happy with 1.3v that should get me atleast another 400 or 500 mhz

Just overclocked my Pentium D 805 on the Asrock 775dual-vsta motherboard from a 3360MHz stable with stock voltage to 3700MHz stable with a CPU pin volt MOD.

I did the 1.420Volt mod and the voltage in the CPUZ is gone from 1.216-1.232 to 1.36-1.376 and has allowed me to overclock my D 805 another 330MHz.

Memory has gone from a 5/6 divider to a 1/1 divider automatically with DDR2 2T.

She’s cranking and so are the temps from 40 idle to 47 idle now, ambient is 24.
Might try a higher voltage mod soon and get this to 4MHz on a cheap Asrock 775dual-vsta motherboard Wow happy happy.

If you try any of these mods, then please let us know of you’re successes or you’re failures etc?

Just overclocked my Pentium D 805 on the Asrock 775Dual-VSTA motherboard again from 3700Mhz to 3880MHz with Shamino's second CPU pin volt mod OF 1.5 VOLTS.

I did the first 1.420 Volt mod and the voltage in the CPU-Z is gone from 1.216-1.232 stock voltage to 1.36-1.376 and has allowed me to overclock my D 805 from 3400Mhz to 3700Mhz.

With the second CPU pin volt mod of 1.5Volts my D 805 has gone from 3700Mhz to 3880Mhz and the system is about 98% stable. I have posted at 4000MHz but might need more juice (Voltage) to keep it there stable. CPU-Z voltage has gone from 1.36-137 to 1.424 1.44 after the pin volt mod.

Memory has gone from 3-3-3-9 @ 3400Mhz with a 5/6 divider at to a 1/1 divider automatically @ 3700Mhz and onwards on my Geil DDR2 ram at 2T.

Temperatures are 24 ambient 44 at idle to 57 under heavy going with water-cooling. The VRM’s are needing good airflow with the extra voltage being produced otherwise everything seems ok.

Here is a great program that benchmarks and also picks up your Memory Speed correctly on the Asrock 775Dual_vsta motherboard.

Asrock realased a new bios for this mainboard.

http://www.ocworkbench.com/2006/asro.../775twinb1.rar

Unofficial 1.90a give us FSB regulation from 90mhz to 650mhz, and PCI-E turbo mode.

Thanks.

Bought this board as a stop gap while waiting for the Asus P5W64 WS Professional's to be available in Australia.

I used the bios from this link and it killed my board, it no longer boots.

Alpha's been nice enough to flash a new bios chip for me from his board.

This guy in link has installed this beta bios it and it's getting him higher overclocks.

yeah but its unfortunately unstable... I dont know exactly where is the problem... is it MB limit or small Vcore... it seems Vcore Boost is the only way to find out...

I tend to agree that it is probably the lack of CPU voltage that is making it unstable but these easy pin volt mods (BELOW) should fix the problem as the bios does not support voltage increase if I remember correctly.

I forgot about one important thing - this bios is only for rev. 2.0 775Twins-HDTV

[RaKLeZ]

New results with better cooling (92mm fan on northbridge)...



max shot for now... still stock vcore...

working on the stability... 355MHz seems to be almost stable (2h priming)...

[Alchemist]

Wow good results dude.

Are you using any volt mods also?

:worm:

[victor89]

He didn`t use any mods yet

[PowerToTheUsers]

Vmem mod:


Put one 50k VR (or 47k) on pin11 to pin13.
The Vr must be at max value (50k) then lower vr value = higher vmem.

Does this mod work on 775dual-vsta too? Is that mod for DDR or DDR2 voltage?

[RaKLeZ]

every mhz counts

and CINEBENCH at 359

For all your 775Dual-VSTA volt mods!
