Needing volt mode or can it be over-volted through bios with RBE v1.24 ....
I tried but its not possible ......... may be WE could find out

Should i flash the ASUS bios.............Ur suggestions can be useful

[thijs]

samsung mem aswell, that's crap :/ hynix mem rox on the 5770 ( or atleast on the V1 )

[overclocking101]

wow that card looks smaller than refrence to? that sux bro

[pr@$r1g]

I know bro , But we can help it out .....................

[pr@$r1g]

here u go MSI also have these samsung ram chips ??

Review @ TPU - MSI Radeon HD 5770 Hawk

And the same controller which i have for vGPU .....uP***

Need Ur help GUYS

[Kubis17]

Please measure this point to GND. Nevertheless I think that will requirement 100K ohm trimr.

[pr@$r1g]

^ Thank'S Bro ,Going to test it soon ....................

I saw it here http://www.cttl.cz/ - - http://www.cttl.cz/index.php?gid=10605 Is there any vMEM mod

It was a great vGPU mod

[Kubis17]

Thank you so much

We had this card in short time that's why we didn't make any vmods of memory.

Vmod's up!


EDIT:

I forgotton the controller for memory.


Please measure this point to GND too.

There is a picture with pleaces where are controllers for GPU and MEM.

[pr@$r1g]

thanks bro

vMEM i got uP chip is there(I should have to check the volts or ?)



But for vGPU uP* chip is a bit different ,its uP6207A1



By searching Google about uP6207A1

Sapphire uses this controller on every custom made ATI Graphics Card
Here used on Sapphire VaporX HD4870

If anybody needs HQ pics i can provide

[pr@$r1g]

Hi guys got this searching uP6207 in google

Voltmod of Sapphire 4730






Its the same chip uP6207AI used with Sapphire custom 5770

Need help ,is it possible to apply to My 5770 ?

I think that it is possible

[pr@$r1g]

yup may be

Is it possible to use this trimmer


Instead of this


Bcoz the 2nd type(2nd PIC) of trimmer is not at all available here & 1st type's(1st PIC) are available ....... im prepared for voltmod guys

waiting for ur replay

[Kubis17]

Second is better, because it is multi-turn and vmoding with it is more comfortable and accurate...

[pr@$r1g]

Bro what if second one is not at all available ???

any other way ,I can apply for ...................

[Roger_D25]

You can certainly make it work with the trimmer but as Kubis17 mentioned you won't get anywhere near the resolution that the multi-turn version will give you (for example if you turn the trimmer pot a tiny bit you will get a big resistance change, the multi-turn pot takes much more turning to get the same change in resistance values). Please correct me Kubis17 if I've got this mixed up? If you can't find one of the multi-turn pots than it might be best to figure out exactly what resistance value you need to get the voltage where you want it (instead of trial and error once its hard-wired in). That would probably be the safest way to do the voltage mod using a trimmer instead of the multi-turn pot. Good luck man and please keep us posted of your progress!

[pr@$r1g]

^ thanks bro ............ these days im looking here & there locally for the better one
thanks also to Kubis17 he has helped me a lot in my progress ..........
Last option for me is to import.........can some one help me with that

[Roger_D25]

I would be willing to ship the parts out to you (where ever you live) but the shipping charges would cost more than the pots (variable resisters), that is the only drawback of importing them from here in the States!

Mine is uder normal circumstance just 930 Mhz Core Clock and default 1250 MHz Memory. pretty good working though.

Sometimes just hung while play dirt 2 using 950 MHz

My Computer Spec

MSI P35 Neo 2
Intel Q9450 @ 443 Fsb x 8
4 Gb Kingston
Club 3D 5770

i just wanna try upgrade the firmware to Overclock edition of Club 3d..i hope i can use 950 MHz clock without make my computer hung

[pr@$r1g]

best of luck with that ............

I have tried a lot of bios ............mine works best with the bios it came with

[ieatrawbacos]

Similar chip is used on my 5850 Toxic, and I think on the 5870 Vapor-X rev. 2.

Would a pencil version of this mod be possible? Soldering things so small is beyond my experience and tools.

Edit: Hmm, i think I see a way to alter the voltage by bridging the VID select pins with conductive paint.

[pr@$r1g]

those volt controller used in 5870 Vapor-X rev. 2 does have more pins on each side ,so its bit impossible to do that ................
One of our kind m8's have also done it here
