Vostro 1500 memory bandwidth

Dear all,
according to Sisoft Sandra my memory bandwidth is well under 3GB/s. Another tool confirmed that: http://user.rol.ru/~dxover/cburst/download.htm
Is that OK?

Thx

 

Interesting.. I just ran the test and I got 4583 mb/s

So it seems that you guys are using Vista, I have XP Pro.
Could it be down to the OS? And if so, are there drivers that could address that problem?
Thx

 

Hi JB,
I moved the blocks out of 1st and 2nd level cache to see the true RAM performance. So my start and end blocks are 8MB and 16MB respectively.

 

runs again with a better result:

For true RAM result, it turned out much better than benzino's result(maybe due to Kingston vs Hyundai?):

Very interesting results
Could you post a CPU-Z registers dump? (last tab "about" has an item "Registers Dump (.txt)"

Mine is attached here.

 

here is the dump file(some content is deleted to avoid possible personal info hack).

 

what does the dump show?

 

a lot of hardware information.
You can download it from
