Oc unstable, faulty hw or psu limits?

Recommended Posts

Posted · Original PosterOP

I build a new pc with these spec:

windows 10
amd 1600af

noctua nh-u12s

16gb ram ballistix sport L 3200mhz 

Msi b450 gaming plus max (latest bios)

Silentstorm cool zero 650w

1tb ssd crucial mx500

1tb hdd 5400rpm (from my old laptop)

Rx 5700xt nitro+
 

so i oc’ed cpu and ram and tested with prime95 (small ftts) and aida64 (cpu, fpu cache, system memory) for 6+ hours each and had no problem, then i tried occt test and had a black screen.

My oc was:

 

4.1ghz 1,35v (than with offset -0.1225)

3600mhz 1,4v (then 3200 with tighter timings still at 1,4v)

1.1/1.15v soc
 

my fear is that 650w couldn’t be enough. 
 

what do you think?

 

Ps (i did a cmos clear and i’m now running occt with stock settings)

Your PC is pulling about 400 watts from the wall, give or take.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

650w is plenty bro. Sounds like your cpu may need more volts to run at 4.1ghz. Although, I don't think you're really suppose to overclock on a b-board, as they aren't powerful enough nor meant for the added stress to the capacitors. 

 

FYI, 6 hours doesn't mean anything in stressing. I stressed a cpu overclock at 20 hours and it passed, but 5 minutes in-game it crashed. Your PSU is plenty.  

 

I just tested overclocks by gaming and day to day use. If it crashed, I went up a bit on the volts. I also would use a spare laptop during this time for school and such in case it crashed during a test. Atleast, till I knew the overclock was stable.

thanks. will try once again starting from the ram this time. the motherboard was a good value but i didn't know it wasn't good for oc, if i decided to change it which board do you recommend? (if you did recommend changing it)

It's really not worth spending $120+ on a board just to get a 10-15% boost in performance. Unless, you intend on upgrading the cpu to a newer ryzen chip than yours.
