Re: The GPD can run Linux!!!

I forgot about it too, and definitely like the sound of that. Mobile OSes are garbage and anything that can be called a proper PC is bigger than ideal for my purposes, and this looks like it might solve that conundrum. I'm not worried about the tech specs; really any old 4x A53 / 2GB phone would be ...

Re: What cases and PSUs are you guys using?

I have read comments that the ribbon cables are very stiff compared to other SFX PSUs and not ideal for small cases. I haven't decided on a PSU yet. Ideally I'd want something cheap that has 80%+ efficiency at circa 30W but unfortunately 150-200W PSUs aren't very common so I may just get whatever's...

Re: What cases and PSUs are you guys using?

NCase M1. I paid a semi-embarrassing amount for it (was over $200 after shipping IIRC), but if a case can be worth that, this one is. 13L, fits all the stuff I want including good CPU coolers and full-size graphics cards, lots of good case airflow options (I'm prioritizing PSU and SSD health and dus...

Re: Chimney-effect low-noise cases

I'd much rather have some fans idling at 500-750 RPM in open air near me than try to muffle fans that need to run 1500 RPM. In addition, the exhaust of this is suppo...

Re: New Ryzen build in a Fractal Nano S

The mITX boards we've got have the full chipset, and the planned ASRock and Gigabyte boards are strongly rumored to also. I'd phrase it as "if you want a mITX system with onboard graphics, Ryzen is going to take a while getting there and won't have such high-performance options as Intel." ...

Re: Chimney-effect low-noise cases

Giant fans are also good, yeah. You need a lot of heatsink thermal mass to avoid the fan use on warm-up, but steady-state airflow isn't tied to heatsink area much at all. A particular exhaust temperature will create a particular amount of static pressure, according to how much less the warmed air in...

I thought about entering this in the napkin sketch contest, but I don't have any need for a new case and it seemed a bit more serious than the usual fare there. Not serious enough that I'll likely bother building it, but serious enough that it deserves its own thread, I think. The basic idea is to g...

Re: NIO EP9 is now the fastest supercar?

Of course the Nurburgring is pretty rough as tracks go, it's just that it's also pretty smooth as general roadways go. If a racecar can handle the Nurburgring, it'll be fine anywhere it needs to be, but if it's supposed to be a high-performance road car, that seems like a pretty low standard for bum...

Re: NIO EP9 is now the fastest supercar?

It's not so much about torque or torqueband shape as peak versus continuous HP. An electric motor's near-perfect responsiveness is great for navigating constant windiness like that (especially compared to anything with big turbos), and the real limitation versus an ICE is sustained power output over...

Am I understanding right that it continued shocking you after you had unplugged it from the wall? If so, the PSU is definitely toast, probably dangerous, and I would make no further effort to debug that if I were you. If that's what's going on, the energy for it is most likely coming from the APFC c...

Don't know if it's still relevant, but I like Zowie for a lot of the same reasons I liked the WMO back in the day.

Re: Your Ryzen Overclock - RAM Speeds Please

When trying to estimate CPU wear rate, I'd go with [halved life per every 10C increase] times [some very steep voltage-based formula I don't know] times the duty cycle. It does depend on quite a few implementation details I'm not familiar with, but if a core is in one of the deeper sleep states, I e...

Cat cores are probably a bad idea. The C2D is enough CPU performance (for Mixcraft), but not by that kind of margin.

Re: overclocking corsair vengeance pro 2133 c11 CMY32GX3M4A2133C11

I'd try 2133 15-15-15-40 (or something similarly unstressful on the timing front), stress test until you're sure that's good (if it isn't then a touch more voltage might be worth a try), then tighten the timings back up from there until it starts having problems again.

Intel has had 6 core parts in their roadmap for at least two years now (probably even longer). It was supposed to be on 10nm as the pointed out, but due to all of the delays at 14nm and 10nm, it's been pushed up to. It's safe to say that Ryzen was not what prompted Intel to make a six core part; it...
