Fairly new to overclocking and needing some help if possible
System:
Asus Maximus Extreme IV
I7 2600K
16GB of Memory F3-12800CL8D-8GBXM (x2)\
Corsair Force GT SSD
I have the CPU O'clocked 12hrs stable on prime 95 @ 4.4Ghz with following Bios Settings
LLC 25%
VCORE Offset Mode +0.025
VRM Fixed Frequency 350
Phase Control Optimised
VCCSA Auto
VCCSIO Auto
Memory Frequency 1600
DRAM Voltage 1.55V
Timings 8-8-8-24-2T
The above is stress testing fine and passes 5 passes of Memtest 86+
I then tried to OC the Memory some more as follows:
Tried up to 1.65V DRAM Voltage for the following
1600mhz 7-7-7-21 2T
1600mhz 7-7-7-24 2T
1600mhz 7-8-7-21 2T
1600mhz 7-8-7-24 2T
1866mhz 9-9-9-25 2T
All had errors show up in Memtest 86+ :-(
The only tweak I can get to work is as follows:
1600Mhz 8-8-8-24 1T and this goes through memtest with zero errors 3 passes so far.
So please can you assist by advising how I can get more from these modules and whether the tweaks may help with the CPU wall I have also hit (44 mutiplier) for a stable setup?
I know my Vcore (1.406V full load in CPUZ) is high for a 4.4ghz setup (66 degrees on air) however I can not get it lower and if I go up in voltage and multiplier it becomes unstable.
I have kind of come to the conclsuion it may be the VCCSIO that needs a manual imput instead of auto, however I am not experienced enough to know what and how to go about it.
All help appreciated :-)
