Re: Questions about 2 builds

1) DDR4-2400 should be fine for most stuff, even on Z270. The big exception that comes to mind is if you've got a 144Hz monitor and want your games to run at speeds resembling that. If you don't want to overclock, don't worry about it. 2) Kaby will be a big boost (the biggest possible) for gaming, b...

Re: A case with LOTs of mounts for fans, and a question about thermal paste

If the rumor is that Threadripper comes with a liquid cooler (which seems plausible), it's probably just 120mm. They're pushing clocks pretty high for a 16C part, but even if it were double the power draw of an 1800X, that's nothing compared to what the 120mm liquid coolers on the Fury X and Vega FE...

Never mind. I thought DDR4 had some features useful for random access patterns that HBM was lacking, and it turns out to be the other way around.

Re: Dumb idea/thought experiment

Some purported (marginally better than WCCFTech-grade, in my estimation) numbers came up in Beyond3D's Vega mega-thread, probably in the page 110~130 ballpark IIRC. That wasn't the source, but that's where I recall seeing such numbers. HBM2 wasn't looking particularly pricey. HBM's performance i...

Surely that would help drive down values in the secondhand market; you'd think AMD and Nvidia would be all over it. I'd think it would move values upwards, at least in the current environment. As is, buyers pretty much assume cards were loaded 24/7 for many months at a time. Legitimately lightly-us...

Re: All Games Crash to Desktop/Freeze

What JAE said. Prime95 and Memtest it and I'll bet you'll find the problem. The Unigine benches put CPUs/RAM under a lot less stress than real games in many ways. This is exacerbated by 4K (lowers framerate, lowers CPU load). All three Unigine benches are also very shader- and BW-heavy at 4K/ultra -...

Re: X299 CPU Power Plugs/Temps (+ X399)

That's not the only edge case that can hurt it by a long shot. Nonetheless, there are fewer cases all the time where an S part would be suitable and an LCC part wouldn't due to performance, and that would be true even if SKL-X's all-core turbos were a few bins lower.

What NTMBK said. I think it must have gotten that "HPC only" rep because it's got a spin-up time on Intel hardware, so if you just toss a few AVX instructions in every few millis it may be a net negative. That spin-up time? 14 microseconds on SKL as measured by Agner. It doesn't exactly ta...

Everyone forgets to even mention the lack of AVX on these. As a consumer (and G3258 owner), I'm sad to see it go, but as a developer, I wish it and the rest of Intel's AVX-less chips to stay gone. If not for this ridiculous b******t, I could default to AVX in the not-too-distant future. As is, what ...

What I most wonder about this whole debacle is who decided that many-core chips like these need to run all-core clocks this high. If you've got a lightly threaded workload that isn't running as fast as you want, you don't have many choices other than turning up the clocks. SKL-X turbo seems good eno...

Most of the boards I've seen can cue case fan control off of either CPU temps or chipset temps, but I'm not sure that chipset temps are that much more useful.

Re: A question for all electronics-literate out there (12V-to-PWM-adapter)

You might find this doc useful. The other issue here is that PWM fans expect a 3.3/5V PWM signal, not 12V. There's a pull-up to probably 3.3 in the fan, so this way the mobo can PWM between ground and open with a basic 3.3V I/O and everything Just Works. This should be mostly solvable by putting ano...

Yeah, having high compression and boost (high peak temps) and always running lean (spare O2 to turn to NOx) makes it tough. Lean burn on a 10:1 gasoline engine wasn't really even doable within US emissions regs until GDI, and that looks very tame compared to a modern 14:1 diesel under high load. I t...

This depends a lot on what you're trying to prioritize.

Also, how dusty your environment i...

Re: Upgrade itch

CPU load doesn't have all that much dependence on resolution. If the GPU can handle it, then don't worry about going 1440p. What you can do to isolate how your CPU is holding up is turn resolution down to something low like 540p and see where frametimes are at. Framerates in that context probably wo...

I'd agree with Waco. There are use cases for which it matters, but most gamers have heavily overspecced power and cooling anyway, and gamers don't tend to use GPUs at a high enough duty cycle to make power costs a big deal. Overclocking's prominence shows how many people out there don't care. I'd bu...
