Hi Res download

[68ZooM]

is there a high res download for the alpha?

[Chilli]

Nope.  Just increase the texture size in the video settings pop up.

UrSelf,

Have you tried creating your own SLI profile for the alpha to run your two GTX260?

http://www.nvidia.in/object/slizone-appprofile-in.html

[68ZooM]

I am working on that but I can't figure out how to link them both together so that the game recognizes more video card memory

[bustr]

I read some blogs and a common theme is some games only see the memory from one of the cards. Have you tried profiles for other games?

[Chalenge]

It doesn't work that way. The memory is mirrored instead of doubled. That way each GPU has its own memory to draw from and can render alternate frames without drawing on the other card for help, and potentially slowing down the whole operation.

[68ZooM]

been in the nvidia control panel would I change it to force alternating frame 2 or force alternating frame 1

[Chalenge]

The only reason to change the setting is if you have the same problem MADe has where SLI doesn't appear to be working. The only difference between 1, or 2 is which card does odd number frames, and which does even frames.

[bustr]

Better question is, chalenge do you actually know how to make SLI work with the alpha and Self is gonna go 20 questions with you rather than you just give him an itemized list of things to do? Do games see a combined single amount of ram equal to the RAM on both cards if the profile is setup correctly?

I was looking at profile editing and it looks like you are addressing register level machine addressing info directly that the OS will then use as fact even if it's spoofing the identity of the two cards in the bus.

On some sites players talk about spoofing the PC into seeing a different card ID for the cards you are running to fool a game into working with your cards. Here from NVIDIA using coolbits they walk through modifying existing profiles.

http://www.nvidia.co.uk/object/nzone_sli_appprofile_uk.html

The SLI Profile Tool lets you see the register level and modify it. Reminds me of programing I\O functions in assembler.

[Chalenge]

You mean in cases where it has never worked? Sometimes you can rotate the SLI bridge and it will be working, or otherwise look for a new bridge. Other times just adjusting the bridge will work.

No, games will not report the sum of the two cards.

My question for Self is how many lanes (physical slots on the MB) is he using? What model MB are we talking about? Are you using a CPU that has only 16 lanes and yet trying to use x8/x8/x4? or worse? Power down, remove everything else, and try it with just the two GPUs.

EDIT: Just to remove any doubts; it is possible for you to completely populate the slots of your motherboard and still get SLI. However, if all present devices (or enough of them) are pushing maximum throughput, then the multiplexing that the motherboard uses to provide additional lanes will not work. When you are sitting idle and checking SLI everything appears to be working. Once you are in the game and other requests fly down the pipe then the SLI function can become unavailable. Normally, if the second GPU can always maintain at least x4, then it will continue to function in SLI. If it ever goes x8/x2 then you are out of SLI goodness. Depending on the devices that are installed it is quite possible for everything to check out at idle, and then completely fail once a game starts up and then the system will fall back to a single GPU. Even then you are in SLI mode, and it will continue to mirror memory as it can, but on one GPU there is no benefit.

When I read about the stuttering that was reported this is what came to mind.

Chalenge  it's a Asus m7ne sli MB(I'm in my semi truck now so I can't check it for sure) but it has two dedicated video card slots that's why I bought it if you run just one video card in it then it functions as pci-e x16 if you run dual video cards then it's splits to x8 instead 16 has onboard audio the only 2 pci slot that I'm using even though there's two more of them available.

[Chilli]

Hold up, pump the brakes    No matter what we do with SLI, we cannot get the game to recognize the second card as additional memory.  Am I correct in that statement?

From what I learned here (thanks Bustr and Challenge) is that the second card will mirror the data received and then alternates / splits the processing of frames (one card then the next).  The bump in speed comes from each card not having to wait to complete rendering the next frame as it's partner has that job, so it only has to render every other frame.  Am I correct in that statement?

The problem that Zoom and I may have with the motherboard, reduces the number of channels by half, and therefore lose the benefit of the additional card in many cases (so far, Aces High fitting that description). If I am correct with that statement, are you saying that there IS something that can be done that will increase speed even with the loss of half of the channels?

[Chalenge]

Okay, thanks to you all for making me actually test it. I can confirm SLI is NOT working in the Alpha. That is, UNTIL you chose Force alternate frame rendering 1, or 2, as outlined earlier.

You can test SLI for any game by pulling up Nvidia Control Panel and on the top menu bar go into the 3D Settings and clicking on "Show SLI Visual Indicator."

SLI is working in AH2, but is NOT working in the Alpha version until FORCED ON. This means that anyone with an SLI setup will not only have to add the Alpha to their NVCP 3D setting, but also force SLI on.

If you still need help with this I will add a thread to show how it is accomplished.

I went looking for your MB and cannot find a listing for it. I seem to remember it from the past, but I cannot find it. Do you have a DXdiag that lists your CPU? Otherwise, I am going to need help locating the MB manual.
