When should I get new ram?

[silverhkswrx]

I am a student that uses several programs at the same time. It is VERY seldom that any of my programs lag or run slow, but as I am getting further and further in my degree(masters in Physics) when should I, or should I even consider 8gb instead of 4gb...

It sounds like you need it now. Only 248$ from OWC http://eshop.macsales.com/item/Newer Technology/8566DDR3S8GP/

lol.... yeah.... thats what i'm trying to convince myself.

I noticed though that macramdirect has 2 types..
Premium Certified HyperVelocity™ DDR3-1066MHz modules for Unibody models
299.54
APPLE FACTORY OEM EXACT ORIGINAL NANYA/ HYNIX DDR3-1066 Modules
349.55

(No tech specs listed on the site)

the ram that Hellhammer is recommending is
Product Specifications:

Technology: DDR3 SDRAM
Density: Two 4GB (4096MB) memory modules for 8GB total
RoHS: Yes
Pin Count: 204-pin
Op. Temp.: 0C to +85C
Data Rate: DDR3-1066
Speed: PC3-8500
CL: CL = 7
Cycle Time: 1.875ns
Voltage: 1.5V
ECC: Non ECC
Module Ranks: Dual Rank
Register: Non Parity
Low Noise 8-Layer PCB
Exceeds Apple/Intel Specifications
Fully complaint with JEDEC specifications
RoHS Compliant
Lifetime Warranty

What is the difference?
Im very familiar with computers and installation but the numbers and acronyms are what throws me for a loop.

Same RAM different manufacturer

well it depends: if u are going to be using more and more apps and/or intensive apps, you might want to upgrade...but if u are going to be using the same stuff and dont mind a few slowdowns here and there, then dont upgrade.

+1 for OWC! I have bought from them twice now and they're top notch.

As for "when to buy", I think the right answer is "when you need it". If your programs are running fine for you at the moment and you're not running out of RAM on a regular basis, then you can only win by waiting it out as prices will only get cheaper over time.
