Overclocking, and Linux install on ECS Z77H2-A2X question
After reading Michael Larabel's article, "ECS Z77H2-A2X Ultimate Golden Edition Extreme" I built a system based on that board.
Newegg had a deal, bundling with G.SKILL Trident X Series memory, DDR3 SDRAM 2400.
I've tried running Mint 13 and Ubuntu 12.10 in Live CD mode; both hang just past declaring the language set. I was successful in loading Puppy 5.2 into RAM; he barked and wagged excitedly ;-)
Then I noticed Michael's comment: "the stock [memory] frequency supported is up to 1600MHz. However, this motherboard does support DDR3-2800/2600/2400/2133/1800 memory in an overclocked mode."
I've never overclocked anything, and have no idea if that's the problem with the other distros.
Can someone help me learn what to do to make sure the memory frequency is accounted for?
I've been doing research on various memory timing settings in the bios.
I've found info on some settings, but so far haven't found info on others.
I've found definitions, but little info on how to calculate remaining settings.
Contacted ECS support, learned they do not supply any info on memory
Checked G.SKILL Trident DDR3-2400 manufacturer web, no joy.
I'd appreciate any info, or links to read, especially how to know or how to
calculate settings for the settings I am uncertain about.
These are settings I am sure of:
CAS# Latency(tCL) 10
RAS# to CAS# Delay(tRCD) 12
Row Precharge Time(tRP) 12
Row Active Time(tRAS) 31
These settings I *think* are correct:
Memory Clock Multiplier 1.00
Memory Multiplier 24
I am looking for info on these:
Command Mode(tCMD) 1 or 2?
Write Recovery Time(tWR) ?
Row Refresh Cycle Time(tRFC) ?
Active to Active Delay(tRRO) ?
Write to Read Delay(tWTR) ?
Read CAS# Precharge(tRTP) ?
Four Active Window Delay(tFAW)?
Refresh Interval(tREFI) ?
CAS# Write Latency(tCWL) ?
CKE minimum pulse width(tCKE) ?
The ata references led me to look at drive settings, connections, cables, then the manual. I realized either the manual instructions
were (to me) incorrect, or I interpreted them incorrectly -- the graphic motherboard illustration IS correct, but I was following text
instructions. I had swapped the SATA 2 optical disk drive and the SATA 3 harddrive connections. After sorting that, the box runs.
