Hi Guys, I installed x64 bit windows server 2005 enterprise edition on a dual processor xenon processor machine with 8gb ram. I installed sql 2005 64 bit CTP (Beta 2)on it. I would like to test SQLperformance on this particular box when indexing. Is there a way for sql to recognize all 8gbOF RAM AND make use of it. I tried to allocate sql to use 6gb of ram ..but it reverts back to the 2gb limit. Is there a limitation? How do I go about setting sql to use all the ram? I dont see sql using all the ram through task manager ... Any insgiht into this will be appreciated a lot. Thanks in advance.
