Building A Computer and Need Some Help!

the ram youve picked, youd be better getting ram with looser timings but faster ie.pc 4000etc, the ram you have down would be great for an a64 system

Damn thats what ive been telling people for ages... whats the point of tight timings if you're not gonna loosen them up and OC

LOL its true .... timings are only important for people interested in sheer transaction speed ... but then again those people are usually running serious rigs with registered memory (i.e., multi-CPU/clustered servers) so its kinda moot point there

those a64 beasts love their tight timed ram, mushkin level 1, ocz eb etc

They do...how do you figure? (btw EB = enhanced bandwidth, not EL = enhance latency = tight times

)

I'm a little illiterate to all you just said haha, but from this list here from the site i am buying off which PC4000 memory would you recommend? Theres so many choices, not sure what they all mean

maybe the guy im referring has el not eb, not quite sure, works a charm though

mushkin seems to do the best job,

either way the tight timings from my view do not do too much for the p4s

Tight timings dont do jack for most people ... if you stop and think about it:
- CPU final clock: 2Ghz
- Board Clock: 133Mhz (NorthwoodB)
- Memory A: 166Mhz (2,3,3,7)
- Memory B: 220Mhz (3,4,4,7)

Analysis A
Net Latency: 113ns (226 cycles)
Transfer: 5312MB/s
Instant (internal) Response Time: 60ns

Analysis B
Net Latency: 121ns (242 cycles)
Transfer: 7040MB/s
Instant (internal) Response Time: 40ns

It becomes painfully obvious that for most people having looser timed, higher clocks results in superior performance (especially when you factor in burst mode where you fire one clock-pass but you grab 8 memory blocks... the higher clocked sticks will dominate that). Now this is not to say that lower timed sticks are no good -- there ARE configurations that benifit from more tightly timed ram (typically stuff measured by transactions/sec but most people dont deal with that ... either that or im really out of touch with humanity which is quite the possibility). For average users, tight memory is a guarantee of overclockability because it means they are guaranteed a certain amount of OC because they can always loosen up their times
