Zotac Expands its GTX 285 Lineup, Uses Accelero Xtreme Cooler

Zotac has yet another GeForce GTX 285 SKU in the making. This time, it plans to use its own-designed GTX 285 PCB with an Arctic Cooling Accelero Xtreme GPU cooler. Zotac isn't using the entire kit, as the NVIO2 and VRM heatsinks aren't compatible with this PCB design. Other manufacturers using this cooler for similar graphics cards include Galaxy, which uses it for its GTX 285 2 GB, and Inno3D, which uses the entire kit for its GTX 280 accelerator.

With the new PCB design, Zotac rearranged the card's VRM area. The design differs from another PCB design for the GTX 285 Zotac designed earlier (read here). The card uses 6 vGPU + 3 vMem power phases. Ferrite-core chokes are made use of, and an extra vGPU phase has been added for redundancy and stability (angled chokes next to the power connectors, pictured below). 1 GB memory across a 512-bit interface is present, with the company making use of Hynix N3C 0.77 ns GDDR3 chips. The clock speeds on this card adhere to NVIDIA's specifications: 648/1476/1242 MHz (core/shader/memory). The SKU is almost ready to be announced.

A big buuuuuuuuuu for every one of those companies, as they are taking ALL the Accelero Xtreme GTX 280s. I want one, but can't buy it anywhere :(

Other than that the card looks nice and will be cool as well with the cooler :)

Looks like another great card from Zotac. I wonder how that cooler will perform in close proximity to another card?

My GTX285 already does better than that, so this thing should be a very nice overclocker.

Would their PWM solution eliminate the electrical noise generated by the card ?

2597 is not an overclock result. 0.77ns=2597mhz, 0.8ns=2500mhz, 1ns=2000mhz, etc...

Out of curiosity, when can we see a place like newegg carrying these?

Yes, I know. My GTX285 has 0.8ns RAM and does well over 2597MHz, so this card should be a nice overclocker, at least on the RAM.

Excuse me for the bump, but this thread was linked from a related news piece.
Anyways, I wanted to clarify those "angled chokes" are NOT extra power phases.
They are pre-phase inductors that filter 12V current. Every single card has such pre-phase inductors.
