Possibility of x700xt 256bit mem mod.

[Unoid]

After looking at the pictures of the 700XT I conclude there might be a good chance you could solder on 4 more exactly gddr3 chips to the rear of the card and achieve 256-bit.

A bios flash would prolly need to take place also. Not sure how to edit the bios though.

Anyone got time to get me some good screenshots of a x800pro and of the x700xt so I can see how likely this could happen?

I doubt there are any pipelines to mod on unfortunatly, but sinc ethis is a totally different core I wouldn't be surprised they have 256-bit functionality in the core hence why they only used one side of their reference boards.

Any thoughts?

uh, soldering bga chips is impobbile unleww you have a solder flow machine, i think and that would only increase the memory size not bus

^^ what he said, you cant add memory bandwidth without getting a new PCB, what you are trying to do is change it from 128MB of ram to 256MB of ram. you could theoretically do it, but logistically its kinda impossible becuase youd need one of those induastrial solder stations

traces for 256-bit seems to be there and the gpu itself may have support but disable in bios.., only reason I have hope is lack of mem on one side and the pcb looks to NOT be missing anything, almost identical to x800pro.

hence i need more pictures.

Well, I remember the 9500 with 128bit bus and 64MB of ram, thay had only ramchips on one side of the core and empty space (for chips) on the other side. And then it was 9500 with 128MB of ram and 128bit bus, they could be softmodded since they had ramchips on both sides of the gpu. So as long as the pcb is the same the card is in theory modable by adding 4 more chips.

the 9500 128 nonpro was 256-bit, thats why it could be modded, and thats why the 64mb ones could only becomes 9500pros (8 pipelines, 128-bit)



and... if u have acess to a solder station go ahead, thats kind of an unrealistic mod

Yes it is, it's kinda like turning a normal P4 30 capper to an EE
