Thanks for the tip and the welcome Dave.. I tried the snipping tool, very nice. :)

Hi. These are my scores. Is it good enough for my system or could I get more out of it?
Cheers. :)
For DDR2 running at 534MHz, it's not bad (mine at 880MHz only gets about 8000MB/s). *EDIT* What you put as "534MHz" in your system specs might not be the effective speed, it might be the core speed... But I'm not sure.
But that would depend on exactly what of RAM you have in there... If you don't know offhand, download Speccy and check what make / model of RAM you've got, post the results here and surely somebody should be able to give you some more info. :)
In my system specs i quoted what Speccy said. It's mean dual channel 533 MHz so it should be 1066 MHz. I have 1066 MHz ram sticks. :)
EDIT: Speccy, RAM section.

It seems Speccy is more popular than I thought then... Lol.
However, regarding your Speccy readout; according to this section, you're running your RAM at 534.3MHz:
But if you look at each RAM stick, only your Corsair sticks actually support DDR-1066, and even then only by means of EPP (Enhanced Performance Profile). All your RAM sticks are PC-6400, which runs natively at 400MHz in dual channel (which gives DDR-800MHz).Code:Memory Type DDR2 Size 8192 MBytes Channels # Dual DRAM Frequency 534.3 MHz CAS# Latency (CL) 5 clocks RAS# to CAS# Delay (tRCD) 5 clocks RAS# Precharge (tRP) 5 clocks Cycle Time (tRAS) 18 clocks Command Rate (CR) 2T
If I'm not mistaken, EPP doesn't function correctly when mixing different RAM makes, I might be mistaken there though... However, that aside: I'm surprised the Kingston sticks are allowing that speed, it appears they don't support it. To be honest (regardless of whether it's just to get better performance or not), do you really need 8GB of RAM...? If not, why don't you take out the 2 Kingston sticks and see how your machine performs then?
Unless you use this machine for working with extremely large images, or for video editing, I highly doubt you'd ever really use even half that RAM efficiently. :) Just my opinion though...
Well speed is about 100-200MB better than before, when I had only 2 x 2 GB 1066 sticks. I especially checked the frequency and stepping when I bought another 4 GB of ram, so they must support 1066. Corsair Dominator were so expensive since they are not in production anymore. I just saw some screenshots like 15000 MB/s on DDR2 thats why I asked. Maybe it depends on CPU?
