How to calculate RAM value on performance per dollar spent
- by Stucko
Hi,
I'm trying to make decisions on buying a new PC. I have most specifications (processor/graphic card/hard disk) pin-downed except for RAM. I am wondering what is the best RAM configuration for the amount of money I'm spending. As the question of best is subjective, I'd like to know how would I calculate the value of RAM sticks sold.
1.(sample)The value of amount of memory:
1) CORSAIR PC1333 D3 2GB = costs $80
2) CORSAIR PC1333 D3 4GB = costs $190
would it be better to buy 2 of item 1) instead of 1 of item 2) ??
Although I would normally choose to have 1 of 2) as the difference is only (190-(80*2)) = 30 as I would save 1 DIMM slot, What I need is the value per amount:
1) 80/ 2 = $40 per 1GB
2) 190/ 4 = $47.5 per 1GB
2. The value of frequency:
1) CORSAIR PC1333 4GB = costs 190
2) CORSAIR PC1600C7 4GB = costs 325
Im not even sure of the denominator ... $ per 1 ghz speed?
3. The value of latency:
1) CORSAIR CMP1600C8 8-8-8-24 2GBx3 (triple channel) = costs 589
2) CORSAIR CMP1600C7D 7-7-7-20 2GBx3 (triple channel) = costs 880
Im not even sure of the denominator ... $ per 1 ghz speed?
Just for your information i'd like to get the best out of the money im going to spend to put on a 6 DIMM slot i7core motherboard.
