Is there significant difference between memory timings 4-4-4-12, 5-5-5-12, and 5-5-5-18?
The price for CAS4 is expensive, about $120 or so.
5-5-5-12 is $30 cheaper, and 5-5-5-18 is about the same as 5-5-5-12.
Now I have 2 GB of that 5-5-5-18 one.
If the difference between 4-4-4-12 vs. 5-5-5-18 is noticeable, I might buy the CAS4, considering this is the last upgrade so I wish to expect an optimized buy and performance.
On the other hand, my mobo supports 1066 OC, so should I buy DDR2-1066 instead? But the price is about the same as 800 4-4-4-12.
I OC only to match FSB ratio to 1:1. My CPU is Q6600 I plan to OC it to "400*6 with 1600 Mhz" so that i can fully utilize all PC-6400 benefits.
How's that? So does tighter timings have 5% effect in that condition? If so, I'll take it.
Cheapest option means I'll just buy more of current sticks. But it's brand is V-Gen, a memory directed towards market of value, with 5-5-5-18 timings.
Is that worth it to replace and change into high-class brand like Patriot? Patriot offers 5-5-5-12 at cheap price.
