EVGA 580 Classified 900MHz EVCA DIRTY little Secret.

[Aberdeen]

EVGA is doing the buyers of this card, DIRTY.

Evga is sending their reviewers and advertisers "special versions" of these 580 Classified Ultra cards that uses the 580 processor p/n GF110-375-A1 that is speced at (Native Base) 772MHz/1710MHz/4008MHz.

The "public" production versions are shipping with "slower" 590 processors p/n GF110-351-A1 hat is speced at (Native Base) 607MHz/1215MHz/3414MHz.

The information I obtained was taken from several current samples of the EVGA GTX 580 Classified 900MHz types.

You can get more performance @ 900MHz* with less voltage and heat using a stock reference GTX 580 3GB card that has p/n GF110-375-A1.

So why did EVGA use a 590 processors in the Ultra? Can it be that the 590 card's are now discontinued and the excess inventory of the 590 processors became "cheaper"?

*using third party programs such as Afterburner.

how do you know that they are 590 GPU's on the ultra's ?

Those're the same part number, how does one tell them apart in that case?

[Chiller]

was thinking the same

From the samples I have they all use the 590 GPU p/n GF110-351-A1 that is speced at (Native Base) 607MHz/1215MHz/3414MHz. And from that base freqs is overclocked to "Ultra Specs".

However I do believe there is a few Classified Originals that have the real McCoy 580 chip and that is p/n GF110-375-A1 that is speced at (Native Base) 772MHz/1710MHz/4008MHz.


This is why some can overclock Ultras over a 1000MHz +, and why others can not even break 940MHz -/+.

Google both part numbers. You will see p/n GF110-351-A1 was ONLY manufactured for the GTX 590 which is speced at (Native Base) 607MHz/1215MHz/3414MHz.

Got pics of the part numbers?

Also, nice edit in the first post to change the part numbers.

Did you ever stop to think that maybe the 590 cores clock better on LN2 and that is why they used that core instead?

This card was designed from scratch with the idea to be pushed to the max with no mods, so I'd say they accomplished that goal.

Regardless they both will still do the rated 900MHz so I don't see the issue.

It's more like Nvidia cleaning shop for the Kelpler. They Ran out of prime 580 chips, so they getting rid of the first run of slow 580 GPU's that was used for the 590, they they dumped the Defective 580 GPUs with defective SM's.

The 570 has one defective SM, the 560 has two defective SM's.

The card was not designed by EVGA by scratch. It appears to be a Nvidias prototype card for the 580 that ended up getting scaled down to what we have today. The switchable dual bios was an original design of Nvidias. There is even provisions for it on the current reference card PCB today.
