Added More Ram and Vista Experience Index dropped from 3.1 to 2.6
Posted on 2008-11-07
I'm puzzled, I expected to see an mprovement when I upgarded the RAM. I have an Acer Notebook Core Duo 1.66 running Vista Home Premium and replaced one of the two 1gb dimms with a 2gb dimm for 3gb total. The memory is recognized correctly and shows as 3056mb But I ran a new experience index and it plummeted to 2.6 from 3.1. and shows memory operations per second as being the culprit.
Since then I've done the following:
1) tested the memory (OK)
2) enabled large address support using BDEdit sucessfully (no difference)
3) checked voltage requirements and latency of both dimms (same)
4) confirmed that the memorys being accessed in dual channel mode (I think) Does anyone know how to confirm this?
Any ideas on what may be causing this or any tricks to properly utilze 3GB of memory in Vista. I've heard that when you enable large address space you may have problems with your kernel running out of space or drivers misbehaving. Is that so? How to avoid it?
