I have Sun Blade 1000 and want to make a maximum upgrade of this machine.
1) what is the differences between graphic cards - XVR-600, XVR-1000, XVR-2000?
2) is it right that Blade 1000 could use two UltraSPARC III Cu 1200 MHz simultaneously?
3) what type of memory and what is the maximum amount of RAM?
The XVR1000 uses a custom chipset developed by Sun and has some drawbacks regarding OpenGL features
some features or extensions are emulated in software so performance in some applications can be severely
Performance is sub par in blender compared to the WildCat based XVR600 and XVR1200
The XVR 600 has roughly half the processing abilities than the XVR1200, to sum it up the XVR 1200 is basically
two 600's on a single card with dual DVI and frame lock.. RAM configuration details are as follows:
32 Mbytes of SDRAM display list memory
256 Mbytes of texture memory
128 Mbytes of frame buffer memory
32 Mbytes of DDR display list memory
32 Mbytes of texture memory
64 Mbytes of frame buffer memory
to get the best out of the XVR1200 a simple mod is required to install it in the 66mhz pci-x slot (last and bottom end pci-x slot) on the Blade 1000/2000.
It requires you to remove the fan assembly and the frame lock/sync portion of the card.
I have a SB2000 with two 1200mhz cpus and 8GB RAM, the 1000 and 2000 have exactly the same motherboard.
So using a pair of the UltraSPARC III Cu 1200 MHz CPUs should not pose an issue, just update firmware prior to swapping
As for RAM .. 16GB should be the maximum .. well .. what I've seen , but i doubt you'll have use for more than 8GB
