can anyone actually confirm the value of the resistor removed for the mod? Ive been looking at the schematic and according to the schematic its a 127k resistor, but the bill of Materials has it as 33k? also it isnt R52, in fact it R139 for anyone who is interested.

Guys...don't be fooled...

You are replacing R139...27k with higher value...47k to 51k... NOT R52...

R52 is in the Feedback Loop of the Voltage regulator...

Refer to the schematics...

I told them this...10 days ago...

Let me share this...:

From unpublished PM reply to Wolfey2014 from April 1 2014...(never sent to him...after looking at his "claims" to others people results and annoying adds all over the place)...:

DVDD+ adjustment -

1. First - cut the small bridge in place of R46...it is a trace on the main board...connecting to last pads to the left of VID0/1 resistors row (R63, R64, R66, R139 and non existing capacitors in between ) ...
2. Second - solder a resistor to these ( now separate ) pads with value = to desired value in the VID chain - 27K (R139) ...these resistors are in series...Rmod + R139 = Rtotal...

So... Rmod = Rtotal - 27K (R139) ...
Example...:
For Rtotal = 47K ...Rmod = 47K - 27K = 20K ...solder 20K in place of the R46 (bridge)
For Rtotal = 49K ...Rmod = 49K - 27K = 22K ...Solder 22K ...very standard value on the top of R46 pads...
etc...

From now on I will call this

"ZiG mod"

...because I don't mind sharing ...but don't want anybody like Wolfey2014 to claim that it is his/her... Wink

I have been experimenting with this since the beginning days of this thread...soldering the trim pot of 50K to R46 pads...this way the voltage to the chips can be adjusted smooth in 10-20mV small steps to check the hash rates...

Another advantage is that you DON"T NEED to remove ANY of the original components from the Gridseed...no de-soldering of R139 ...

And one more advantage is ...you CAN REVERSE the voltage mod to the ORIGINAL by simply removing the Rmod from R46 pads + restoring the bridge R46= 0 Ohm...or even simpler...making short on Rmod/R46...

Hope it is bringing more light ...and understanding of what Exactly are we all doing...Modding VID reference on the Voltage regulator chip of Gridseeds...That's it...!

Thanks for reading this...and ...Good luck modding...!

ZiG

Edit...: Some body was exploring the idea of external small switch ( Like DIP switch to be able to go in "MOD/Overclocked" to "Normal/Stock" speed ...I have that switch soldered at the ends of my trim pod ...and it is doing exactly that...MODE SW "OC/Turbo - Stock/Normal"... using the short of R46...or trim pot value...

Enjoy...

Pea Ess,, I see that Zig has chosen to backstab like a punk, and make false accusations (backed up with Vapor PM evidence even Roll Eyes

) and try to black PR me to others - all behind my back of course -...
Even if there is any such PM, he has completely misduplicated it. Who do you think you are, PIG?
Well, there is not one shred of truth to what it states!
I never claimed anyone's work to be my own. That is complete dub in and someone went wild with that false rumor' Zig... and is spread it maliciously trying to discredit me.
It is clear to anyone with neurons what his agenda behind these kinds of attacks is. COMPETITION!
My only claims have only always been of my own discovery or creation.
I acknowledged the originators of the mod when I copied and applied it to my own pods which is what I first talked about and posted pictures of.
Where I say "my mod" it refers specifically to my discovery of the 49.9k value and the use of a simple, readily available 1/4Watt Axial resistor. This IS my mod!
Everyone else, just about, was using SMD's.
I also referred to my mods as the mods I physically did for myself and others. Those ARE my mods, duh! Wink

As for which resistors or caps to change, in the beginning, I never ever claimed them to be mine in any way shape or form!
This is the truth!
Zig will probably keep on nattering about me for a while. It only shows, he's done things he shouldn't have and has to find ways (even made up ones) to be right about it. Wink

I am a veteran senior technician and I know what I am doing. I am not perfect. I still make mistakes like everyone else, even stupid ones! Cheesy

Oh, and I still don't agree with going pasty pasty on the seeds. Mine use the original pads and have presented absolutely no signs that they pads don't work or are interfering with the processors causing HW errors.
I believe if there is an interference problem with the chips, it's a capacitive issue between the top cover plate, the ground planes on the pcb and a bit of emi too. It's not a fiber issue.
Making the changes may help the heat sink issue with all chips not being properly heat sinked otherwise, but increasing or decreasing the gap between the pcb and top heat sink's plate changes this capacitance and the HW errors either lessen, go away or get worse.
That's what I'd look into first if my pods were having that problem.
And I solved the uneven heat sink issue by torquing the screws evenly snug.

Welcome back Wolfey2014...You resurrected like a Jesus after the Easter... Wink

Did I say in my post... "Nothing personal ...just your annoying adds all over the place"...YES I did...you could check few post earlier...

But you are back...and you are starting again...calling names...same OLD style...aggressive temper... etc...

Just DON'T ... please...chill down buddy...I have nothing against you...and appreciate your good effort and results as well as everybody else here...it is a community effort...

But don't start this again...Relax...please...Get a drink, take a breath before posting like this... I don't want you banned again...

Thanks

How stupid do you think I am, Zig?
You're still trying to be right.
Get the correct view point, kid!

You owe me a retraction and an apology for lying about me!

Do that, and we can make nice and be friends...if you want.
Or keep trying to be right about it. I really don't care!

One last thing.This stuff is OFF TOPIC and should not be taken up on these threads.
The correct thing to do is, if you have something personal to say to me or about me, be a grownup and PM me. That is what someone who "likes me" - a 'friend', would do.

Personally I don't care to be liked or admired. I simply do the best I can in life, and come what may.
I am constantly striving to improve and learn from my mistakes.
