Nvidia GeForce GTX 560 ECS Black OC Edition

Despite the relatively low price ECS asks for its Black Edition card,
the company applies a factory core overclock of 870 MHz core,
though the 1000 MHz memory setting is almost identical to Nvidia's
1002 MHz reference spec.

Its two six-pin power inputs sit on the side of the card, just like the
reference version. If you own a smaller chassis without much room
behind the graphics cards, plugging in stiff power leads can be
problematic. Admittedly, that's more of an issue for folks who own
longer boards, though.

ECS’ reference GeForce GTX 560 cooler uses three 8 mm heat
pipes to transfer heat to aluminum fins positioned radially away
from the GPU cooling block. A single 3” fan pushes air through
the plastic shroud.

Based on Nvidia's reference model, the presence of two DVI
connectors and a single mini-HDMI outputs are no surprise.
Again, though, you're only able to use two displays at a time.

A DVI-to-VGA adapter, two dual Molex-to-six-pin power adapters,
a mini-HDMI-to-HDMI adapter, a driver disk, and user manual
are included with ECS' card. Given its value-oriented price, the
bundle makes sense. Basically, you don't get any frills aside
from the core overclock.

Overclocking

We’re happy to report that this model cooperates with MSI’s
freely-available Afterburner software, which let us push the
card’s 0.987 V default setting to 1.15 V. This facilitated an
astounding 1010 MHz core clock, which was the highest seen
from any vendor. Is it likely that our sample was hand-picked
for its scalability? Quite possibly. Should you expect similar
results? As with any exercise in overclocking, your mileage
will almost assuredly vary.

This card's memory wasn't as accommodating, though the
1200 MHz we managed to push is still quite respectable.
