4870x2 - Hypermemory (one for the experts)

What does GPU-Z say? How do you like your card and what kind of performance are you getting in general usage and games etc.? Also in the bios or during the boot what does the system report for GPU mem?

I think thats how much of your RAM is being allocated to help the VRAM do its job. Or something like that.

there isn't a crossfire option for the 4870x2, it is a single card.

oh and my own one says

1gig of gddr5. it is probably being misread somewhere along the line, i wouldn't worry about it.

i am unsure how to answer that post as it was clear i was meaning his system is misreading something not my own.

Its advanced memory management technology makes more efficient use of all the available memory in computers with PCI Express® technology. Graphics applications can share system memory and use fast on-board memory for real-time processing between the graphics card and the computer’s memory. This ultimately increases the affordability of ATI’s Radeon™ graphics technology.

--- Therefore how do I know If I am sharing system memory or not, my memory reading is too low. Can this be disabled?

Even if my card runs out of memory, there is NO way that using the system's RAM would be *near* the same as using the VRAM. The GPU would waste more time waiting for the CPU to allocate his memory needs than waiting on his own address space.

It's a neat tech for slow video cards, but hi end can't even THINK of using that. Maybe, and only maybe, on "2D over 3D" apps (video and non-real-time rendering).

The other way around sounds like a smarter move though, but it would still have performance penalties of memory intensive apps cause of the paths it has to take. The CPU would have to wait even more cycles to get that memory in practical terms.

Anyway, my opinion

Esop!

Firstly, I wasnt claiming itd run faster than it does with vram, let me clarify that. What I was saying is that itll run faster thru the pci using system ram than going all thwe way around and still using system ram. This usually shows up in 2 areas, low end low ram cards or mobiles. Not sure why hes seeing this

Hi, I'm have the same problem as the original poster and was curious about an answer.

I see 767mb of hypermemory in CCC for each gpu

I have the Asus 4870X2 Tri-fan card.
Vista 64 bit
8gb of Corsair Dominator 1066 memory
Asus M3A78-T mobo
