what RAM do I need for 4810tz??

I know its ddr3, 8500 but what speed 1066 or 1333??

will making it 4GB make any difference? i've got windows 7 64 bit

 

The chipset supports DDR3 up to 1066 according to Intel.
Upgrading RAM will help you only if you're running out of it at times- if you don't there's no point in doing so. Keep an eye out on RAM usage when heavily multitasking to see how much RAM is used up- then decide.

 

As far as I recall the two processors you were deciding between both have a max FSB speed of 800Mhz so 1066 or 1333 will both be ok (very very very small improvement over 800 and then only if the RAM timings are better than 800)

How much RAM do you have ? 2GB is the sensible minimum,
3GB sometimes worthwhile for photo editing, media coding etc - but your processor may already be the bottleneck here not the RAM
Give 3G the benefit of the doubt on a laptop as it means less HDD reading in some cases. 4GB is justified if a 'beefy graphics card' still wants to share memory (e.g. My ATI HD5650 has 1GB of its own but still borrows up to 1.7GB off the OS). 4GB Performance improvement over 3GB . . hmmmmm I wouldnt spend money do it
More than 4G. Hard to push a laptop hard enough to warrant this and remember if you use hibernate you will have a 4G swapfile and a 4G hibernation file on the HDD already. Take it to 8GB and you secretly lost 16GB of HDD space and a ton of money for a marginal performance improvement

 

Hi!

Download the freeware CPU-Z and in the SPD-tab you can see the specs. My 4810TG shows PC3-8500F which is 1066 Mhz. Upgrading your ram may improve overall performance but it depends on your using habits. Moreover some graphic cards (like the Ati in my 4810TG) share some of the ram with the system.
Hope I could help!

 

thanks all, i'll stick with 3GB for the time being!

may increase hard drive to 500GB instead!
