Hello guys, i just enabled SLI on Rampage Extreme X48 with both XP SP2 + GTX 285 and Vista + GTX 295....Some fun in 01/03 to come i hope

Awesome Benji, be sure to share your results

119k already done, 6G, 730/1375 on SLI 285...but aiming 125K

Hard because my RE only allow 1 memory stick

6.1 benching, run order and 121 800

EDIT :

No cold bug until -165, so too much cold for my poor insulation. Will be back again tomorrow

But SLI is working quite good, the 1k missing is probably due to the single channel memory.

Yeah it's great fun, I'm having issues with the board not loading windows a second time after enabling SLi with dual channel ram - with single channel it works fine. Very strange issue. If anyone has experienced this and knows a fix please let me know.

wow
shame about single channel RAM

your results are really weak....its gotta be all from that single channel RAM i guess ....do you have separate tests listed?
