Ram upgrade to 8GB

[azreal1983]

I currently run windows XP (32 BIT) with 4GB of RAM.

I am upgrading to Windows 7 64 Bit version.

I have a Asus Motherboard P5K-VM.

My question is about the Ram to buy.

I plan to get 4 x 2GB modules.

Will i not a massive difference between the follow:

DDR2 PC2-8500 CL5 -

PC2 -6400 (800MHz) DDR2-SDRAM Unbuffered Non-ECC CL6 (as in http://www.lambda-tek.com/componentshop/index.pl?prodID=B127652&viewOverview=y&showold=#productTop)

I understand the second the second is slower but will i notice with 8GB? Its a lot cheaper but i dont wanna cripple my machine

On a second point which is going to be quicker PC2-8500 CL5 or PC2-6400 CL4

Cheers

Hi newcomer and welcome to the Tom's hardware forum.

1- The difference between 800MHz (PC2-6400) and 1066MHz (PC2-8500) isn't significant.

2- For Win 7 x64 is enough with 4GB or 6GB, this depends of your processor.

3- Maybe you never use the 8GB with the games and applications that exist today.

Thank you for the help.

I have read that setting up 1066MHz ram can be a bit of a pain. Is it work just sticking to 800Mhz?

Cheers

Also I have found this RAM:
http://www.overclockers.co.uk/showproduct.php?prodid=MY-190-CS&groupid=701&catid=8&subcat=813

and

http://www.overclockers.co.uk/showproduct.php?prodid=MY-192-CS&groupid=701&catid=8&subcat=817

are they the same thing just own in overclocked. Could I run the cheaper fast ram at 800Mhz?

Aren't the same RAN. The 1st is PC2-8500 (1066MHz by default) and the 2nd is PC2-6400 (800MHz by default), a OC RAM is a 800MHz by default running at 1066MHZ

So its best of going for the cheaper PC28500

No, the PC2-8500 is more cheap, but is not too good. The CL is high and the Voltage too (2.1v). The recomended voltage is 1.8V or less.

 

[azreal1983]

The motherboard can support upto 2.1v

Yea, but isn't recomended.
