Questions regarding BIOS options..

[ETSA]

ACT to ACT Delay

Rank write to read delay

write to precharge delay

read to precharge delay

Explanations, links or optimizations would be appreciated..

I am curious about manually setting these, as of now they are on AUTO, I would like to have the optimal settings...

BTW this has to do with memory..

tRRD (ACT to ACT Delay) has little to no effect. It is the delay between back to back activation commands to the same module. You can leave it at auto, it's as close to unnoticable in even benchmarks as you can get.

tWTR (Rank write to read delay) is how long it has to wait after a write command to issue a read to the same module. It will make copy bandwidth a bit better.

tWR (Write to PRE delay) has about the same as effect on performance as tRRD. It's the delay after each write operation, before an active bank can be precharged. This delay is required to make sure the data in the write buffers can be written to the memorys before the precharge for the next read/write operation.

tRP (Read to PRE delay) guess what it does (I'll give you a hint, not a whole heck of a lot )
