Ryzen OC Issue.... PSU?

[BrokenBladez]

So, I have the gigabyte K7 board. Ryzen 1700, Gkill RGB Model F4-3200C14D-16GTZR, and an EVGA 750 G3 psu. The issues I'm having while overclocking are not reboots or BSODs. Instead, while stress testing my screen goes black, system keeps running, and I have to hard reset. Then it boots fine again, no issues. The reason I'm asking is because My OC is absolutely Fine (4.0) @ 1.375v for cinebench and other cpu benchmarks. When running P95 though, after about 20-30 minutes, I get the black screen. I've upped the voltage to a max 1.425, and it actually happens faster with the higher voltage. Seems... Odd, to say the least.

As an I.T. specialist by trade, my senses are tingling that this is actually a PSU issue, and not an issue with my OC. What do you think? Have you had black screens with Ryzen?

If it is failing prime it isnt stable . Cinebench isnt a stress test .

Yes, I gathered as much. My point/question is that what it's doing is odd behavior compared to any other time I've OC'd. The black screen, no reboot, gets worse with higher voltage...

The rest of my post is mostly what I wanted to talk about.

Its a new system from what I have seen thats common with ryzen . thats how they crash .

Power supply problems usually shutdown the PC.

Yeah, it usually does. After some more testing I had errors in P95 without the black screen after 10+ minutes. They were higher number sets, so could have been my RAM overclock. Starting at Square 1 - stock settings and P95 to make sure it's not a base hardware issue.

Ahhh, all for the love of OC'ing.

Is it common with Ryzen? From a quick google search it seemed most people wouldn't boot/shut down/bsod. If you've seen it though, I'll take your word. Might have to settle for a 3.9, which is a shame, because at 3.9 I still have a tenth of a volt to play with. Ugh.

I dont have a ryzen but I have hear the black screen from a few ppl when talking about their overclock

I would set your ram to 2666 and then run p95 again. I had loads of issues trying to overclock my 1600 and they were all ram related.

I have the gigabyte gaming 5 board and I will guess that the bios’s will have similar settings on them and maybe the same issue

Yep RAM is still a significant problem in the AMD/Ryzen ecosystem, with XMP timings having been developed for Intel CPUs. My Ryzen 5 1600 has no problems running at 4 GHz (3990) with the RAM at 2133. The issue was getting the timings correct so the Corsair Vengeance DDR4-3000 RAM would run at 2933. The same RAM runs at 3000 in my Coffee Lake Intel system by default. So, yeah, set the RAM to default (2133) and try again.

I surmised it was my CPU OC. I ended up dropping it 3.95 ghz, ran prime for an hour no issues.

As for memory, I spent literally 20 minutes OC'ing it. Managed to get 3600 @ 14-14-14-34 timings at 1.45v. Had to reset bios once when I tried 3600 @ 1.4v. Haven't tried pushing any higher yet, but pretty impressed with how easy that was. I do, however, need to stress test it overnight to make sure it's 100% stable. Ran prime for a half hour without any issues.
