ASUS Designs Own Monster Dual-GTX 285 4 GB Graphics Card

ASUS has just designed a new monster graphics card that breaks the mold for reference design GeForce GTX 295, called the ASUS MARS 295 Limited Edition. The card, although retains the name "GeForce GTX 295", same device ID, and is compatible with existing NVIDIA drivers, has two huge innovations put in by ASUS, which go far beyond being yet another overclocked GeForce GTX 295: the company used two G200-350-B3 graphics processors, the same ones that make the GeForce GTX 285. The GPUs have all the 240 shader processors enabled, and also have the complete 512-bit GDDR3 memory interface enabled. This dual-PCB monstrosity holds 32 memory chips, and 4 GB of total memory (each GPU accesses 2 GB of it). Apart from these, each GPU system uses the same exact clock speeds as the GeForce GTX 285: 648/1476/2400 MHz (core/shader/memory).

Each PCB holds 16 memory chips, a 6-phase digital PWM power circuit, drawing auxiliary power from an 8-pin PCI-E power connector, the GeForce GTX 285-class GPU, and its companion NVIO2 processor. The PCB holding the PCI-Express bus interface, also holds the bridge chip. ASUS broke away with using the nForce 200 chip, and instead is using a yet to be disclosed third-party bridge chip. Currently, PLX and IDT are two likely sources for such a chip. The memory consists of high-density 0.77 ns memory chips made by Hynix.
The electrical-management on each PCB is care of a Volterra VRM controller, which supports the I2C interface, which means that the card supports software voltage control, perhaps a big plus for ASUS' Voltage Tweak feature that is gaining in popularity. Fused power circuit provides Over Current Protection while also facilitating extreme overclocking.

The cooler internally has the same basic construction as the reference cooler, it uses a single leaf-blower. The card spans across two expansion slots and is slightly higher than the reference design card. ASUS also used slightly longer internal bridges that make more room for third-party coolers, and the likes. Our source from ASUS EMEA conducted a quick 3DMark Vantage test proving the card's seamless compatibility with existing drivers, while also providing a significant boost in performance over existing GTX 295 cards. Being Quad-SLI capable, this card finally makes GeForce GTX 285 (effective) quad-SLI possible, and makes for the most powerful desktop multi-GPU setup ever conceived. ASUS designed this card despite pressure from NVIDIA enforcing its rigid policy of restricting its partners from custom-designing GeForce GTX 295. If everything goes smooth throughout the development process, the card might make it for a gala launch at Computex.

I tell you this, my next system will be Intel based, and I must... must have one of them cards!

Asus fan boy?

H*ll yes!
quad socket nehalem EX (64 threads) minimum 24GB of ram, and two of those in SLI.
Oh and 8 256GB SSD's in raid.
and then buy me one.


anything less would starve this card of its required awesome factor.
(and dont forget the 3000W PSU)

Has anyone still not noticed the unrealistic clocks?

3 of these would fold like theres no tomorrow..... let alone the 45k in 3dm vantage i'll have....

expect a few of these to show up at my house pretty quickly. :pimp:
Dang. youve got an oil rig at the back o yer house? :P

Is it just me or are the overclocks extremely unrealistic.

There is no way a GT200 is capable of 833 core and 1861 shaders. That and the memory is far too slow for a GTX 285

Voltage tweaked probably.

There could be other reasons too, like change in stock cooler, using WC or something.

Time to strap a box fan to the side of your case :D

Yes, those clocks are unreal for that cooler.

I suspect water / Dice pot on that with some daft voltage tweaks. Its like they do with car adverts - "the brand new Ford Crazymobile from only £6,995" - They show you a model with gorgeous alloys, metallic paint, a sporty looking spoiler, yet the small print says "Model shown Ghia 1337 model starting from £9,995". Its just a way of tempting buyers in.

You think it has dice on it? You don't customize cards before you buy them though. I bet its air/water with voltage tweaks, and if it runs hot... *shrugs.

alright i'm going to admit this, due to a little confusion.

is this just a custom 285, or is this a DUAL 285 - four GPU's. cause the screenshot says 4 GPU's on the GPU-Z page.

the screenshot says 4 because two of these cards are running in quad sli. imagine this cards physical appeareance like a gtx 295

Good question, 4 would be rather insane, I thought a 285 had 2 physical gpus though, I only see 2 gpus on the die.

In games NO ! since it`s GDDR3 , the performance might actually drop in some games .Take HD4870 for example . The card uses GDDR5 , and you barely see any difference between the 512 and 1024 version , just in really high resolutions when you run out of buffer . But again , no big difference.
some what true but there are small differences between th 512mb > 1024mb cards & it all depends on how you run your games. from my understanding running with 16xAA is better with a 1024mb card due to the space available to buffer/store all the textures.

Depending on the resolutions, settings u play at & also games. you may see upto 3-5fps increase. but for performance boosts on anything above 1024mb then thats still debatable but from what I have read it hardly makes any difference at all unless u play at super high resolutions on a 40-60" monitor. - its all debatable.

512MB to 1GB isnt about gaining FPS, its preventing the sudden slideshow when you run out.

Run a gaming PC with 4GB of ram and drop to 1GB - everything goes slow and stuttery when you run out. its not about boosting FPS over 512MB cards, its about preventing the slowdown when you run out of memory.

same goes for 2/4GB cards.

that's what can happen if you give the card to hardcore pro overclocker who's not afraid of the rma department. and no i doubt he's not using air. note how it says "done by kinc"

edit: lolforgot to insert a "not"

This is with liquid nitrogen thermal solution installed on the cards. I didnt have time to insluate well enough so cards are only running -40C with 1.175V set via software (up from 1.15V). There is headroom :)

Well now that explains it :rolleyes:

Any chance of a real world bench (i.e stock clocks? Or Air OC?)

Maybe just one card?

That pic screams of e-penis.

i think is a collector's edition
My guess too. You see 1/1000 on the picture.

Makes me remember of the 1950XTX Uber edition that had ony 500 card made.

Yeah kyle2020 suggested dice, I was kinda questioning the suggestion since there was not space for it. It makes me oogle though.
