Gigabyte R9 290 memory mod

[rsnubje]

Hey guys,

 

I'm looking for the mem mod of this card, however it's not really working as it normally does.

 

This is what I believe the memory controller:

And here is the datasheet: http://www.anpec.com.tw/ashx_prod_file.ashx?prod_id=60&file_path=20080917100144843.pdf&original_name=APL5915.pdf

 

Resistance to GND is 6.7K. A friend of mine has tried with FB to GND with a 200K pot, but no matter how far he lowered the resistor, the mem voltage wouldn't go up.

 

After looking closer I think there should be a variable resistor over R352(on pic, R1 in datasheet) to Pin 3, which is Vout, but I'm not 100% sure so this is why I post it here. It could also be that we need to alter R2 (R353 on pic) also?

 

Any help is appreciated.

I suppose that are controller for 1.8v rail

mem controller should be at the back of the card near 8pins area

Thanks for confirming my doubts

 

The one you probably mean is coded 5230 RYE, but couldn't find a sheet on this. I coulnd't find anything else that would be for mem.

same mod as the ref card

Awesome, thanks! Only just now I see the resemblance with the ref card:P Not that different.
