So let me see if I've got this straight. The Samsung TCCD IC's are the "black chips" and the Brainpower PCB is the "board" that all the black chips are mounted on? And put together they make wicked sweet RAM which over clocks really well?
Yes yes and more yes.
but I don't understand why and isn't that just a trade off (more clocks per second but also more clocks to perform commands)?
Yeah it is a trade off, but there's not a huge differen in bandwidth between 2-2-2-5 timings and 3-3-3-8 timings really, but there will be a huge bandwidth increase behind 200MHz at 2-2-2-5 timings and 220 at 3-3-3-8 because with a higher frequency more information can go through.
Technically there is a trade off, you have to find the highest frequency with the tightest timings, if your timings are too loose, then you lose that extra bandwidth gained from the extra frequency, but mind you you'd have to have REALLY loose timings to lose it all especially once you got beyond 250MHz, it'd have to be like 5-5-5-8 or worse before you'd notice that it's actually running the same or slower than 200 at 2-2-2-5
3. Well I don't see how you would come to the conclusion that it doesn't help much. If that were the case why would people do it
Heres my sandra memory benches from when I was OC'ing my RAM:
DDR400 - 200MHz - 2-2-2-5-1T 2.6v @ Approx 3000/2800
Those end numbers are the numbers Sandra shows, the 3000 being the top number in the graph and 2800 being the bottom number, effectively meaning read and write.
Now here's some OC'd benches since the ones above are stock:
DDR470 - 235MHz - 2-3-3-6-1T 2.7v @ 3616/3368 - CPC-ON
So as you can see, even though my ras to cas and ras precharge (middle numbers) are looser at 3, there is a 600mb/sec increase in speed for the read and a 500mb/sec increase for the write.
Like I said those timings don't make THAT huge of a difference, you'd probably only notice it if you went from 200MHz at 2-2-2-5 ti 205MHz at 2.5-3-3-7 that you'd notice no difference.
Here's a bench of speeds that wasn't stable on my system, but it was because of my motherboard, not the RAM itself:
DDR500 - 250MHz - 3-3-3-8-1T 2.9v @ 3779/3495
So see, 3-3-3-8 is valueRAM timings, but the first 3 (cas latency) and the 8 (cycle time) DO NOT effect bandwidth, they effect stability, so even if it was 2-3-3-5 that score would be basically the same. As you can see there it's a 750+mb/sec for the read and almost 700mb/sec for the write
That basically tells you right there why it's worth it, and on an AMD64 system, stock PC3200 would get almost 6gb/sec so OC'ing the RAM on those can give you real benefits, and newer Intels since they have better memory controller than socket A AMDs
Also, I read about a CPU:RAM ratio of 1:1 :
4) What is this comparing? FSB and RAM frequency?
Yes it is. You always want 1:1
