ip35 pro + corsair XMS2 RAM, appropriate BIOS settings?
I understand that the timing for this RAM is incorrectly detected as 5-5-5-18, but is intended to be 4-4-4-12. I've heard as well that the voltage is off too. It's been a long while since I put a machine together from scratch, and I need some hand-holding on this one.
My processor is an e8400, nothing is overclocked.
These are the options under ADVANCED CHIPSET FEATURES:
CAS Latency Time (tCL)
RAS# to CAS# Delay (tRCD)
RAS# Precharge (tRP)
Precharge Delay (tRAS)
(I know that these are represented by the four numbers 4-4-4-12, but there are also the following options
Refresh Cycle Time (tRFC)
Write REcovery Time (tWR)
Write to Read Delay (tWTR)
Act to Act Time (tRRD)
Read to Precharge (tRTP)
Currently, all settings above are set to 'AUTO,' by the SPD. If I manually change them, I know what to do with the first four settings, but what do I do with the other 5?
I tried to just change the first four options to 4-4-4-12, left the rest to AUTO (and I forgot to change the voltage). Windows refused to boot up, informing me that config.sys was missing or broken. changing all the settings back to AUTO allowed for a successful boot to the OS.
What are my settings? Is there an article i can read? Does anyone have this config already who could help?

This is what memory he's probably referring to:

I'm using the same memory, and would also appreciate having the same information.
It seems like the bios "ought to": automatically detect and then enable the correct timing and voltage settings.
Thanks in advance.
