Yeah ,lower memory then yours too, my memory is at 2933 in that test 2866 now, ill try a manual Oc run later ,see if I can get clue as to what's up.
yeah so i manually clocked it to 4 in the bios and its better, i pushed a bit further with ryzen master(1391cb 173sc) but at 85 degree max temp im chickening out for now until i get a mono block ,and possibly more rad because i've only got the Ek coolstream 360 on this system now , with just the cpu and vega waterblocked, i like it but i get mad coil whine from my vega at high clocks or fps.
this case is nice, lian li 011 dyamic, i feel its crying out for another 360 in the roof though, especially now.
That looks about right. I'm just below that at 4ghz with my RAM running 3400 @ CL16. Probably the only reason I'm only 20 points behind.
Also, just for fun I pushed 43.25. Those fuckin 4 points are
killing me though, man! Why couldn't it
just give me 1500?! I didn't have the time/energy/will/daringness to try for 4.35 and fix that little problem. Eh, I could push the ram up a little and that would to it. Tomorrow I may give that a quick run.
I tell myself I can go higher, maybe 4.375, though I'd never get it truly stable. In fact I did try booting it, though I never tested for fear of cooking things. It booted and did basic things in W10 no problems. The 4.3 config, I was able to push through some linpacks and realbench, but on my... I think, decent air setup, temperatures get dicey. Not OMG FIRE, but definitely uhhmmmmm...
I often wonder what this Scythe cooler would do in a full size ATX case. Having only two front intakes and rear exhausts holds me back. VRM's are just as much to blame, I think. I can see the exact point where the voltage droops unusually and then it all goes to shit. All signs point to VRM's overheating. Not good. Didn't take long for me to give that shit up! I'm tellin you guys. Can't say I blame them, CPU is showing just over 200W! It honestly gave me the jitters to see that.
But really, if I wanted to ignore the fact that peak temp during those tests was 86C (
) I could easily run a flat 4.3. It averages closer to 80C when pushed to the max - just little 3-5 second jumps up past that. Cinebench MC maxed at an admittedly high 73C. Voltages look okay, just below 1.4v - though realistically probably a little higher. But I'd probably be looking at 70C for gaming and the various other things I do. That honestly doesn't scare me a ton because of my actual usage - I know I'd very rarely even approach 80C, but with my PC sitting right next to me in this small 10x12 room, it's a lot of noise and heat to live with. I also don't know if it would ever be truly stable, or if it would just seem to be... ...or if I'm brave/dumb enough to run prolonged stress tests at those temps. Maybe P95 blend or something not AVX-heavy.
So yeah... all around ridiculous thing to do. I can't imagine.
I can tell you this. I ran it there for a couple of hours and ran a few different stress tests (albeit briefly because of temps,) and it tossed out not one WHEA error. So that's promising. But I already know that with this chip, that temperature zone will lead to crashing all on its own over time. And again, VRMs are of major concern. I think that might be the real reason for the problems. They aren't tossing the heat like the CPU itself is. They're running away past a certain point. Sustained loads will knock it out every time. I could probably time it if I wanted to.
If my cooling was better I'd experiment some more. I think with a good custom loop it would definitely be possible to go further into this territory, but I don't wanna go there... ...with all of the expense, potential for failure, maintenance... ...nah. I may try to experiment with ways of cooling the VRM's much later on. I could put a 40mm fan up in the corner where the two VRM heatsinks meet. And then another on the bottom of the CPU VRM heatsink. Maybe even see about pushing more air across the whole mobo. I dunno, at the end of the day, the restriction of the case is the real limiting factor. It can only move so much air before it is saturated. Maybe I should try popping off the front panel and filter.
I just... I'm not ready to fry this chip/mobo yet. Maybe when Zen 2 hits
Pretty cool to see it hit that, though. I've wanted to push 4.3ghz on air since I bought this chip. But if I'm completely honest with myself, I like it at 4ghz much better. I don't notice the performance loss at all and I pretty much never hear any fans save for my loud-ass RX 580. I was looking at my max temps after running fallout yesterday and it was 50C flat! To me, that is excellent. A good balance of performance, temperatures, and efficiency, for me. Clearly this is where my 2600 most wants to be. The 2600 is a really capable lower-upper range CPU that doesn't ask a whole lot in return. That's what it's best for, imo. For when you want something serious, but don't need to go ham on everything, for not a lot of cash. The everyman's gaming/enthusiast chip
