Some interesting points here..
In this case it is more that every 2 years I update my DAW system. As
low latency is an important factor for this kind of system I buy quality
RAM that is rated with low latency CAS RAS e.t.c. I don't go for the LED
ram but I don't just buy the most expensive I try and find a balance..
With this system.. I already have 1 GB of low latency (2-2-2-5) quality
RAM but in the system that the 4200+ is coming out of I have 4 GB of
cheap RAM but it has been running 24/7 for a couple of years in a home
server box ..
So the question is, should I stick with the low latency stuff and leave
the system at 1GB or put the cheap RAM in it ... 4GB is probably
overkill so, I was thinking using only 2 of the sticks.. It would seem
that as VDPAU is going to lower the load on CPU and RAM, then the only
consideration is compile time (this is a gentoo box).. but again I run
distcc so not an issue.. I really am leaning towards staying with the
1gb of low latency corsair ram..
(For anyone who is interested, I am actually swapping in my DAW box
mobo, CPU and RAM into the home server for this at next upgrade in one
month primarily because it has been running 24/7 for around 3 years and
I am concerned the caps are going to give out on the mobo which is an
older agp model.. the DAW is a newer solid cap design mobo so it should
have around 22 years 24/7 usage on it on the caps anwyay... I also have
another 939 PCI-e mobo that was my main mythtv system until I bought an
Antec NSK 2480 and needed to find a micro atx mobo for that system. See
it's all incredibly complex... and I kind of wish I never got this IT
bug.. ahh but then I wouldn't have the job I have as a software
engineer...classic catch 22 )....
