    Memory Bandwidth in L25-S119 is awful

    So I got a L25-S119 in one of the $400 dollar deals last week. For that price you cannot complain, right? Well actually one thing bothers me. I don't know exactly how to put it, but quite simply in the venacular, the memory bandwidth completely sucks. It has DDR2-4300 that is running at a normal fsb of 4x100, since it is a Celeron-M. So it is actually running at PC-3200 speeds. Memory timings are 4.0-3-4-9, and not accessible to the user. Opening up Sisoftware SANDRA, I hoped to get performance not too much worse than the DDR PC-3200 ram in my desktop. What I actually got was:

    Benchmark Results
    RAM Bandwidth Int Buff'd iSSE2 : 1968 MB/s 62% Bandwidth Efficiency
    RAM Bandwidth Float Buff'd iSSE2 : 1969 MB/s 62% Bandwidth Efficiency

    On my desktop, I can achieve ~90% Bandwidth at 2800 MB/s. So my query is, is DDR2 supposed to suck this much? Is there anything short of a pinmod that would increase memory bandwidth?

    Can anyone else with a L25-S119 system or even with just DDR2 in their laptops help me out by running SANDRA's memory benchmark and posting their results? The link is here:
