I recently built my new rig in a CM Storm Stryker (although why the storm trooper is black and the white case is called something else I'll never understand) and have a couple of questions specifically about overclocking the RAM and CPU on this motherboard and some of the issues I've had in doing so. Components as follows:
ASUS Sabertooth Z170 Mark1
Intel i7-6700k
G.Skill Tridentz 3200MHz 32GB (2x16GB) 15-15-15-35 RAM
CM Hyper 612 v2 air cooler
SanDisk 240GB SATA III SSD PLUS
2 Other SATA HDDs, 750GB and 1.5TB
Firstly, Ultra X4 750W PSU then HydroG 750W PSU
Win8.1_64bit
I was first using an Ultra X4 750W Modular PSU. When I first started the new computer using bios version 1101 (10/23/2015) I was able to turn on X.M.P and load into windows. CPU-Z read 1600MHz so I thought I was all good. Upon further use, basically adding the drivers and updating windows which has lots of restarts I noticed it would almost never restart or shut down properly. 1 in 5-10 times it would properly restart or shut down. I would then have to hold down the power key until it shut off, turn the power back on (about a 25% chance here of getting an "overclock failure" error message when booting up) go into bios and then restart from there and would load into windows okay showing 1600MHz. Lastly, I updated the bios to the most recent version 1602 01/01/2016) and it wouldn't even post. Just gave me the 4 beeps in a row ASUS hardware failure notification. So I put the bios back to 1101 and used until I made my next move.
After reading a lot of reviews about how bad Ultra is, reading your report of quality PSUs and thinking back to my old computer where the PSU came from and how it would never load into windows the first try, it would always freeze and shut down at the Win8 rotating circles load screen on first go and then would ALWAYS finally load on second go, I ordered and installed last night a FSP Group HydroG 750W PSU. With this PSU, NO VERSION of the bios will post with X.M.P. enabled which pissed me off, but in trying to work around that I manually changed the bios settings for DRAM voltage to 1.35V, the speed to DDR4 3000 and the timing to 14, 14, and 34. The sync all cores was already selected, seems to be default. And I kept the Ai Overclock Tuner on Auto. These settings seem to work fine and I have no problems with restarting and shutting down or hibernating thus far, only been one night.
Question 1:
My first question is about overclocking the RAM. Is it safe to reduce the latency as far as it will go while still posting and seemingly running okay? Or could this potentially reduce the lifespan of the RAM or damage it in any way? I used the 3000@14-14-34 settings based on the idea that the cycle time (9.33ns) is nearly identical to its actual G.Skill verified rating of 3200@15-15-35 (9.375ns).
Question 2:
Could increasing the voltage over 1.35V for the RAM potentially get the 3200MHz to work. That's over G.Skill rating so is that a bad idea?
Question 3:
I plan on overclocking my CPU as well. Should I do that first, optimize it and then overclock the RAM after the CPU? Or if I consider the overclocked RAM more important then the CPU, should I OC the CPU with the already overclocked RAM?
Question 4:
For overclocking the CPU, I was going to:
Ai Overclock Tuner--> Manual
Sync All Cores
Change the 1-core value to 45 (which should change all cores since synced right?)
Change the CPU Core/Cache Voltage to manual mode (should I use adaptive right off?) and change to 1.35V.
Save and restart and if it posts, test stability using Realbench and checking my temps to make sure they stay at or below 80°C when maxed out under load.
If all goes well and is stable, change CPU Core/Cache Voltage to Adaptive and change Additional Turbo Mode CPU Core Voltage to 1.37V. (+0.2V over CPU core Voltage).
Question 5:
Any idea why the supposedly great sever grade components Gold certified PSU won't let the RAM go to 3200MHz where the supposedly crappy un-steady PSU would?
Any help on this is a big thanks.
