ASUS P5B-Deluxe; Problems & Fixes

[ziddey]

you not going to try 400fsb 4:5 eh?

look at your results. better latency at 400fsb. better bandwidth at 400fsb except for sse optimized, where read is slightly worse and write a fair bit


edit: you can also play with the static read feature. it helps a little bit as well, but can possibly be tricky to get stable.

That said, here's my p5b at 400 1:1 4-4-4-8-4-20-2-9-4-10 static read faster:

Access latency 56.6 ns (181 clocks)

Read datarate (INT) 6838 Mb/s
Write datarate (INT) 2935 Mb/s

Read datarate (MMX) 7323 Mb/s
Write datarate (MMX) 2936 Mb/s

Read datarate (SSE) 7564 Mb/s
Write datarate (SSE) 7271 Mb/s


and 400 4:5 500 4-4-4-4-4-25-3-9-4-10
Access latency 48.7 ns (156 clocks)

Read datarate (INT) 7440 Mb/s
Write datarate (INT) 3141 Mb/s

Read datarate (MMX) 8194 Mb/s
Write datarate (MMX) 3140 Mb/s

Read datarate (SSE) 8579 Mb/s
Write datarate (SSE) 7267 Mb/s
