Let me say first, ever since first talking to you when we worked on systool and the Abit boards, I highly value your opinion.. I'm not questioning YOU I don't do "marketing spin".
So please don't take my comments personally. As you know, I can get carried away sometimes. What's sideport for on RS? Why would they name two totally different technologies exactly the same? Is it not the direct interface to system memory? And how would this not work the same to access memory of another gpu? It could be enabled via driver, but not in public releases, due to "No performance boost" Can you explain how eyefinity works across crossfire then?
If it works like normal crossfire, then how come it's not supported on RV, as of yet? Last edited: Nov 26, W1zzard said:. This PCI Express auxiliary memory channel is effectively a bit memory channel with access to system memory. This means that a VPU equipped with a bit local graphics memory bus and a PCI-Express auxiliary memory channel has an effective bit memory bus.
The SidePort is a bit DDR memory interface that the integrated graphics can use either instead of or alongside the Athlon 64's memory controller. SidePort only - In this mode, the integrated graphics core treats the SidePort memory as its local memory. If more memory is needed, it is allocated dynamically through system memory by the driver, which is significantly higher latency than the local SidePort memory.
UMA only - In UMA mode, the only memory to which the integrated graphics has access is a dynamically allocated partition of system memory. If more memory is needed, it is allocated dynamically through system memory by the driver. The integrated graphics core will first use SidePort memory until it runs out, then using system memory. In this mode, the integrated graphics cores will request data from both the UMA space and SidePort memory. Despite the fact that UMA accesses will be higher latency, the dual ported nature of this setup improves overall performance.
There are situations when a SidePort only configuration will offer greater performance if the application depends on lower latency memory accesses. If more memory is needed it is dynamically allocated through system memory by the driver.

Either way rendering on the screens from the photos I have seen looks OK, and still allows a huge number of pixels and thus a large advantage in gameplay. Last edited: Nov 27, Sideport is the extension of the ring bus interface, or the crossbar onto the memory mapped addresses of the PCI-e lanes, that also allow the use of direct memory addressing by the GPU to the systems memory to hold extra data.
But the crossfire bridge is much faster than the PCI-e lanes, and are proprietary and thus could be tied into the core of the GPU without interfacing possibly. Not to be considered a extra any amount of memory channel width due to the huge performance hit taken when data has to be fetched from main system memory.
The first monitor i use a DVI cable to graphics card one and monitor number two i use a DVI cable to graphics card nummer two. The third monitor a use a DVI to displayport adapter. Stoltish , Dec 21, You have to use all 3 monitors on GPU 1. Since R9 and up, you dont have use active display port adapters to use more then 2 monitors. Agonist , Dec 21, Stoltish likes this. Hi now eyeinfity works but when i try to start anything in full screen my computerer freezeses and reboots.
And 3Dmark gets an error before it starts.. But if i play in window mode everything works. I thought it was a dead gimmick of the past. Anyone says the opposite is dangerous.

Reactions: Kdtut'z. If you have visuals maybe I can understand? Kdtut'z said:. Click to expand Ok I'll Review It. JC I can understand but here is the problem I attached pictures 1st thing is that I can't group all three monitors to make it as 1 only the two and I think it is in the connection problem maybe? According to what I have read on multiple sites, if you are trying to get Eyefinity to work, you must have one monitor connected with a Display Port connection.
It has to either be a monitor that has a Display Port connection or you must have an "Active" Adapter, not a "Passive" one. Trying to make this easy for you, so my suggestion and you can take it or leave it , but I would buy the adapters that I have listed above and use those to connect ALL 3 monitors to 1 video card. At that point you can get Eyefinity to work properly.
I would try downloading and installing the It brings a ton of improvements to eyefinity that may help you out. I am not really too much of an expert with this so I can only provide links, but not much help. Maybe GhostRyder can provide some insight. When I get home ill show you with some screenshots how I setup my eyfinity if this does not help enough.
