Differences between the same card - GTX 580 - does anybody knows?

[rbuass]

Hi friends!

My friend got 2 GTX 580 Lightning brand new.

He is not extreme overclocker, then he told me i can choose one to use under Ln2.

when disassembling the boards, I noticed quite a difference in the two.

One is black and one brown.

The capacitors, while the same capacity, are also different.

In black you can read everything that is written on the chip and also see the nvidia logo, and brown, it is very difficult to read.

I think the same way as occurred with the GTX 480 (when the orange PCB were better than the green PCB), I wonder if anyone has any information on these boards or even on their batchs.

 

The black

46N3A8 1045A1

N3F110.000

 

The brown

06N3A3 1106A1

N3R791 01P

 

I appreciate any information on the extreme overclocking performance of the VGAs, cuz I only choose one and I can not test the second.

 

Below the pics to show the differences

 

 

 

 

Thanks in advance for all

Hola mate !

 

Don't know anything but that mine seems to be the black PCB one or the brown ...but with inscriptions on caps I'm sure.

 

Benching around 920/1200 and 950/1250 max on air with 1.15v

 

Any differences between their way of scaling atmo ?

Did test Black PCB yesterday.

It reaches about 1480 3D11...

Lots of RAM freezing but no problem to run 1300 (RAM).

Can not bench colder than 155....but still fine VGA.

Only difference is that it's a different PCB vendor, same goes for the Hi-C CAP.
