Hi I'm trying to oc my system a little bit and need some advice*
My specs: motherboard: Formula ix CPU: 7700k CPU cooler: Corsair h110i Gtx RAM: Dominator® Platinum Series 32GB (4 x 8GB) DDR4 DRAM 2400MHz C14 Memory Kit (CMD32GX4M4A2400C14) GPU: SLI 1080 strix PSU: EVGA 850w
So far my overclocking looks like this
XMP 2667mhz 14-16-16-35-1 1.35v All cores 4.6ghz SVID SUPORT: DISABLED CPU core/cache current limit max: 255.50 CPU cache ratio: 4.6ghz Manual core/cache voltage: 1.23 max CPU VCCIO voltage: 1.18750 CPU system agent voltage: 1.18750 * *
CPU load line calibration: level 7 CPU current capability: 140% CPU vrm switching frequencicy: 500KHz CPU power duty control: EXTREME CPU power phase control: EXTREME DRAM current Capability: 130% DRAM power phase control: EXTREME DRAM switching frequency: 500KHz
Everything's looks and seem to run ok but I have encountered a problem
I set my ram to XMP 2667mhz 14-16-16-35-1 1.35v and then using the drop down menu I set ram to 2900mhz and select manual DRAM voltage of 1.4v all seem to run ok but I want a nice and clean round number and I tried set it to 3000mhz but system won't boot it starts but just hangs there I have tried VICCIO and system agent voltage 1.20v and maximus tweak 2 but still no boot.
DO I need to push something harder or change ram settings more or are my ram already frying it's self since it's supposed to run. Ihave corsair dominator platinum airflow fan running 4000rpm mode so I don't think heat is a issue.
PS DRAM voltage is purple does this mean I'm blowing up my ram? Same with VICCIO and system agent it's yellow does this mean I'm on the edge just wondering cuz I always had white numbers.
I'm a bit confused ref. the RAM....that kit is a 2400MHz kit right? you say XMP 2667...does it have an XMP profile for this?
For a 2400 kit 3000 is a substantial OC and you might have to relax timings...like 15-15-15 or 16-16-16
I would not worry about DRAM voltage even up to 1.4V....maybe you would have to try a bit more vccio and/or vccsa to get this working...my XMP 3200 ram sets 1.22 vccio and 1.2 vccsa....I'm not sure if that's high for this platform...have to ask about that...
OCing RAM for most things is not going to gain you much
Well maybe 3000 is a step too far but keep tweaking...maybe relax cas 14 to 15 or 16? but compare performance of 2900 with current settings and 3000 with relaxed timings and you might find you are better off staying at 2900
How does all my other settings look ? Is it all under the safe limit ?
Funny in aida64 Extreme I get hardware failure test stoped when I try to do stress test but realbench passes 10h and prime95 pass10 hour and after all I'm just overclocking by like 100mgz stock 4.5 to 4.6ghz and cache 4.2ghz to 4.6ghz that she not big oc weird Aida give that problem maybe just bug cuz Aida have not been updated for along time maybe it's not supporting 7700k cuz the program is not even showing voltage and or stuff like VICCIO *
