64 GB Kit RipJaws (F3-12800CL10Q2-64GBZ) in an ASUS P9X79

Thanks TMan - Any other things I can try whilst we wait?

Minor Update

Crashed again - didn't expect it not to, no changes since the last time. I went ahead and upped two of the voltages. I now look like this:

Here are my voltage settings (manually set)

CPU VCORE Voltage 1.190
CPU VCCSA Voltage 1.200
DRAM Voltage 1.550
VTTCPU Voltage 1.19375

Primary Timings (manually set)
10
10
10
30
2

Secondary Timings - (All "Auto" set except as noted)
DRAM RAS# to RAS# Delay 5
DRAM REF Cycle Time 255 (Manually Set)
DRAM WRITE Recovery Time 12
DRAM READ to PRE Time 6
DRAM FOUR ACT WIN Time 24
DRAM to READ Delay 6
DRAM Write Latency 8

Is 255 the highest it allows?

[G.SKILL]

in these case, will suggest if you can replace for another kit, since you had tried lots of adjustment, please exchange with the distributor or send it back for RMA. and it will more easy to see which part cause the issue.

It goes up to ~ 500 I think - How high should I try?

I thought we were just getting started! Where I am now is a new beginning (read entire thread) as I had not started from "fresh settings" but instead had used XMP settings and possibly even tried the auto-overclocking.

I am willing to continue tweaking here -

If no one else jumps in, I'll be on the forums this afternoon, hopefully with some fresh thoughts

[cdub]

OK - I found the perfect mix of what it takes to crash this thing allowing me to steadily bump up voltages till it stopped.

This shows the "history" of increases.

CPU VCORE Voltage 1.185->1.19->1.200->1.225->1.300
CPU VCCSA Voltage 1.200->1.250->1.300
DRAM Voltage 1.550->1.580->1.600
VTTCPU Voltage 1.18750->1.2000->1.3000

Primary Timings (manually set)
10
10
10
30
2

Secondary Timings - (All "Auto" set)
DRAM RAS# to RAS# Delay 5
DRAM REF Cycle Time 208->255->275
DRAM WRITE Recovery Time 12
DRAM READ to PRE Time 6
DRAM FOUR ACT WIN Time 24
DRAM to READ Delay 6
DRAM Write Latency 8


Remember my intent is NOT to overclock necessarily. Are there ram timings I can back off on maybe sacrificing a tiny bit of performance for added stability while maybe being able to lower some voltage?

Thanks to any / all responders.

[Tradesman]

How about trying

DRAM RAS# to RAS# Delay 7
DRAM REF Cycle Time 310
DRAM WRITE Recovery Time 12
DRAM READ to PRE Time 8
DRAM FOUR ACT WIN Time 27
DRAM to READ Delay 8
DRAM Write Latency 9

with the DRAM at + .05 VCCSA 1.25 and the MC voltage (CPUVTT I think) at 1.22

[cdub]

Will give it a go this evening. I don't quite understand the part where you say

"with the DRAM at + .05 VCCSA 1.25"

[Tradesman]

Add + .o5 to DRAM voltage from stock and set the VCCSA voltage to 1.25
