I CRCed my console dumps and tested a few of them with MD5 after someone said CRC isn't valid anymore. If they passed CRCing they passed MD5 checks. I think if you're not worried about an actual adversary you can verify with pretty much anything.

For home use, yeah, you can use pretty much whatever because the collision space is large enough on even MD5 that you're far more likely to have your system just randomly catch fire than than suffer a live collision. When you're an enterprise dealing with hundreds of terabytes of poo poo a day, or some hostile nation state trying to engineer an intentional collision, that's another story.

DrDork posted:Even colliding SHA-1 would take a completely infeasible amount of file storage to even begin to talk about, and I think by default ZFS dedup uses SHA-256. And if you're just doing simple checksumming without dedup, there's even less of a point in using SHA-512, but I guess if it's hardware accelerated then do whatever. On a home system with any sort of modern CPU it is unlikely to matter from a performance stance, anyhow.

If combined with integrity checking and optionally encryption (like GEOM/GELI in FreeBSD can do), it's perfectly reasonable to implement it - which is what the FFS/UFS creator is currently working on for FreeBSD.

LPDDR4X at that speed is real expensive. The next model up is 400 bucks more with more memory being pretty much the only change in specs.

I'm sure it's a more expensive than the more pedestrian 2400Mhz RAM, but there's no way it's costing $100/GB, either. Offering a 4GB version instead of just bumping the base price by $50 or so might buy them some additional sales, but I wouldn't want to be using anything specced out like that.

Khorne posted:Welcome to OEM laptop pricing. Lenovo was charging $300 to get a 250gb ssd last year when you could buy a better one for $50. For boring old RAM they often charge $150+ for an 8gb stick you could buy for $32 yourself. Yup, they know how rear end it is to service those things as opposed to a desktop (if you can even crack it open), so they figure "oh we can charge you an arm and a leg for features that would be easy to upgrade normally". Like my old Dell, from 2007 mind you, had a special adapter for the HDDs.

Yeah, quite familiar with OEM gently caress-you pricing--Dell was asking $580 to toss in a 1TB Intel 660p to a laptop we were speccing out last week, which I think runs for under $150 on Amazon these days. Just saying that Dell offering a 4GB option instead of a minimum of 8GB is almost certainly not because it's just ~*~so expensive~*~ that they couldn't afford it, and a whole lot more so that they wanted the ability to stay "starting at $999" in ads without actually intending for anyone to buy the $999 model.

heh, i was surprised when a recent BIOS update for my Asus Z370 board finally let me boot the RAM’s XMP profile. This is what the voltages were set to with everything on auto:  Im temped to ask their support of they consider this safe but nothing good has ever come out of me contacting Asus support.

Khorne posted:Between 1.4V-1.5V is safe for RAM depending on manufacturer, heat situation, etc. z370 is desktop so you're well in the clear. The spec for VCCSA and VCCIO are usually less than 1v, Asus is running them both over 1.4. That being said, I had to run them at 1.3v on my 9900k to get 3200 MHz RAM stable in XMP.

I’d try dropping your VCCIO and VCCSA voltages to 1.25V or lower, everything I’ve read says you can trash your IMC with voltages above 1.3 on those. My 3733 ram is stable with them around 1.17.

My 3733 ram is stable with them around 1.17. Yes, I’m aware of that. The RAM runs stable at 1.18/1.21V IO/SA when set manually but these are the voltages that Asus sets for people who just set and forget XMP and don’t take the time to double check. The 5 GHz profile also set 1.48V Vcore under load (not SVID but actual indicated Vcore). Im curious if the Asus engineers know more than we do wrt safe voltages or if long term reliability is simply not something they take into account as long as it boots and it’s stable.

The standard laptop here had the same resolution until about a year ago. They were also in the range of i5 x200s with 4gb ram and mechanical HDDs and they expected people to use them. Now we get quad core i7s with 8/16gb ram and surprise surprise we're now spending about 5 million a year less on buying everyone Surface Pros.

My father in law works for a giant defense contractor, and every few years buys a surplus 3 year old laptop from the company for $50 or something. They were all ridiculously nice with huge, high resolution screens, absurdly high specs, and absolutely trashed batteries. Probably cost $2500 when new. Pretty good arrangement when the government is paying for them.

The government facility I worked at for years used much the same thing, but with the bonus of forced full-disk encryption, and hosted on what had to be an upstream trunk of ~10Mbps. Using them was utterly miserable, and I would regularly catch file transfers to the shared folders puttering away at <200KBps. We also bought a few dozen "new" 19" 1600x900 monitors instead of 24" 1080p ones because the purchasing clerks still had the paperwork for the 19" ones from like 2000 or whatever, and figured it'd just be easier to re-submit that than actually do a new order with modern equipment. Those monitors cost over $200 each, because they're something of a specialty item now.

Just put together a system with a 9600k/ASUS Prime Z390-P motherboard. I put on XMP to get the RAM timings right and ensured it didn't mess with anything else. I'm using a Noctua NH-U14S cooler and all Noctua fans in my case (Fractal Meshify). Realtemp/HWInfo shows idle at around 33-34c. I guess this is a good temperature? One thing that is confusing me is that all of those programs show the CPU at 4.5/4.6ghz despite me turning off the ASUS "enhancement" stuff in the BIOS. I have Windows set to balanced power mode. Isn't it supposed to ramp down when not under load?

Asus announced new X299 boards (yes, a 2 year old platform) with lots of LEDS, OLED screens marketed at gamers and I can't help but wonder who buys this stuff. Maybe Intel is planning reposition X299/Cascade X to better compete with Ryzen since the consumer platform seems stuck at 8 (soon 10?) cores. https://www.youtube.com/watch?v=VqPO3CE7C-0&t=3371s https://www.computerbase.de/2019-08/asus-rampage-vi-extreme-gamescom-2019/

Well there is an 8/16 right now from Intel, so its more about pricing. The best leak we've seen so far is that the Comet Lake S stuff isn't gonna happen until March 2020. It seems likely that there will be a 10 core i9 part at the top of the stack.

Power is two PMICs, one per die. Whole package is 12mm x 12mm, about the size of a dime. Pretty unreal.
