First look: SLI priced as mainstream computer
Until now we've showed you two 8800 Ultra's, one that is overclocked, EVGA's SuperClocked 8800Ultra, and Gainward's BLISS 8800Ultra at reference clocks. EVGA is clocked higher but that didn't stop us to do SLI and overclock the Gainward card to match EVGA.
You guessed right, we tested the Geforce 8800 Ultra SLI at "Superclocked" clocks of 655 MHz for the core and 2250 MHz for the memory. For now we will just show you the 3Dmark results, since we are just testing Lost Planet DirectX 10 and the results will be here shortly, so be sure to check them out soon. As we play around with Lost Planet you can check out what these cards can do in SLI. Bear in mind that these two cards come with a price tag of a normal mainstream system, about 1500€.
We tested them under Windows XP, then under Vista. 3DMark for DirectX 10 is going to come out soon and what we can see from the results is that older 3DMark versions will work better with DirectX 9 and Windows Vista. We were surprised to see that after enabling SLI under Vista, we had to restart the system, which is not the case under XP.
EVGA Geforce 8800Ultra works at 655 MHz for the core and 2250 MHz for memory, while Gainward works at reference 612/2160MHz. When paired in SLI both cards works at a reference 612/2160 MHz. The situation is different than before when the clocks in SLI adapts to the faster card. Now we had to set the clocks on the cards manually to 655/2250 MHz. Gainward's card did well with EVGA "SuperClocked" clocks and we didn't encounter any issues during the test in SLI.
