4.5 at 1.3 1.35 1.4 passes fine just higher temps.

 

4.6 and 2.1 input still doesn't work.

 

4.6 and even 2.3 cache doesn't work

 

Just tried 125 strap stock speeds 3.5 and 1333 memory. Auto vcore was at 1.14 and passed fine.

 

Now just tried 4ghz same setting and vcore wanted 1.15 and bam instant shut down with benchmarking, wtf??? Ugh

Yeah tried everything. It has to be some kind of protection being enabled because its highly unlikely the 1x increase can reach tjmax In 1 second when 4.5 is stable at 70 degrees 100% load. When previously overclocking Asus rampage 5 extreme and Formula z97 I always got BSOD when trying for higher clocks or saw crazy temps at higher voltages, never a full power off in 1 second. This is my first build with asrock and I am not very happy.

Yeah I have no idea. It won't even pass boot at 46x and 1.35v. I can only boot and load windows with my 4.5 settings then try to tune to see anything. If I do higher then 45x in bios and restart it just hangs. doesn't even display anything. It just shuts off after around 15-20 seconds. Very frustrating because this is a brand new build, days old.

Those values. Boot fine, benchmark fine, stress test fine. Anything over 4.5 hence 4.6 and pc turns off when testing. I read somewhere that it could be my power supply with ocp enabled and its drawing too many Amps for the 12v rails but after reading a lot online my ax860i should be able to handle any overclock and single gpu. I don't have corsair link enabled to disable and check but that doesn't sound right

Win 7

5930k 45x 4.5ghz 1.269 stable

45x cache 1.269 stable

Xmp 2666 1.2 ballistic elite

Asrock mini itx x99

Ax860i power supply

Gtx 970

1.9 input

72 degrees max in stress testing

 

 

Those settings verify and for the life of me I cannot go higher then 45x. Whatever I do when I start to benchmark at 46x+ it immediately shuts down. Even if I put the core voltage at 1.3 1.4 1.5 no matter what it shuts down within 1 second. I don't see any thermal throttling. I can't tell if it's the VRM shutting down or what's going on. I have tried no xmp , lower cache settings, 1.8-2.1 input. Speed step on and off, blck at 125 and lower multiplier, nothing works.

 

Any ideas as to why it is shutting down when going beyond 45x?

 

Note when doing 46x at 1.269 volts it BSOD and I am thinking the voltage was too low but when I raise it to even 1.299 it shuts down. I can't tell if it's a bios issue when the voltage goes to high or what. I don't see any temps over 75 so far.
