RAM Optimization

Hello there,
Here I am again, seeking some good advices :P

I just made a RAM upgrade from 6 to 8 GB and it feels like almost nothing happened. A few details OS Win 7 x64, Intel Core 2 Duo E6750 2.66GB, HDD 1TB (not SSD, true can be the main cause), 4 X Corsair 2GB DDR2, 800MHz, PC2-6400, 5-5-5-18 on Intel DP35DP mainboard.

Having said that, I have a few questions.
Is there any RAM tweak that I can do in order to improve the speed of the above described machine ?

SDRAM Frequency section from BIOS for exemple, is set on Auto. The other options are 333/266/200/133Mhz. Unfortunately I can't understand how these values are related to memory module specs and CPU's FSB .A few "how to" details will be much appreciated .

Please find attached print screens exported from CPU-z, to have a full view.
If you need more details, don't hesitate .
Thank you,

Thank you for your reply,
True, in my case there are 2 Corsair XMS2 pairs with the same technical specs. One pair bought initially a few years ago and another pair a few days ago. They are not listed on the Intel page (that's also true) but until now - Thanks God! - the system was stable with 1 or 2 pairs of RAM installed.

Also I've read and fulfilled at that time, the Intel System memory features (18V, DDR2 800 SIMMs with SPD timings of only 5-5-5).

Reading the Intel forum post, makes me think that I'm so lucky :) because as I said, there are no BSOD screens just I have the feeling that I can obtain a better speed in this configuration. If someone know what's the deal with that Bios Frequency speed, will be just great .

For RAM you also need to upgrade symmetrically. Did you have 6 GB with 2GB and 4GB? thsi is odd...
i think you have duel channel board, so you always want to go up in pairs (this would be different for the expensive triple and quad channel boards)

the amount of RAM is OK for you. what is slowing you down is the HDD. Nowadays electronics progress enables everyone of us to drive a Porsche. but for some reason we equip that Porsche with Oxcart wheels called HDD. Get an SSD and you will notice a difference. In addition follow above advice on memory.

Thank you guys for your feed-back.
I had 2x2GB + 2x1GB in dual channel (6GB) for a few years now. I've made this upgrade 4 x 2GB with 2 pairs as I described above a few days ago.

Regarding the SSD storage devices , I'm not so confortable with that limited numbers of write/read cycles; That's why a HDD represent my best option for the moment, of course with the price I have to pay (slower speed).

if you use it heavily you may get 10 years of life, if you use it less, even more. byt the time the SSD wears out your display will have faded away, your battery is dead, and your Mobo is blown up and you don't want the 10 year old laptop anymore anyway.

The average HDD in heavy use may live 8 years on average. SSD may live 10 years, why are we concerned about SSD life but not HDD life?

Consumers are funny that way. With incandescent light you get 1000 hours of life out of a light bulb and no one is concerned. With residential LED bulbs you get 30,000 hours and everyone is worried about that "short" life expectancy.

how about SSHD drives, they could be an option ?
