How many linux distros does one person need?!

Haha, legitimately I personally spent half an evening downloading a poo poo tonne of Linux ISOs to try out recent distros and see what those crazy free range kids are up to. It's actually the only use my torrent client has gotten in a long, long time. So sometimes it is Linux!

Oh also my question. What's the hubbub about TR4? AMD has promised AM4 will be several generations but I haven't seen squat on TR4. What's the official word? Not that I can afford it, I'm just curious as to why they'd tout the longevity of one and have zip on the other.

I have no complaints about the reliability or performance of the system, which is indeed great, but it seems that in 2017 you just can't build a system without a bunch of "bling bling" LEDs. I obviously "have a problem" with bling bling - and I'd very much like if I could turn off the lights on my 1080 and RAM sticks. :(

You can't bridge a 970 with a 1080 y'know. ;) I'm using the GPUs as standalone daughterboards for BOINC/number crunching. Nerd poo poo. :)

I used the crunch for Einstein@home with my old 7850 and World Community Grid too with my CPU with the old goon team when that was a thing.

Building a new system (i7-3770K to Ryzen 7 1700) and I'm prepping my flash drive with motherboard drivers for the ASRock X370 Taichi. Does anyone happen to know what's in their "AMD all in 1 driver"? It's dated for February so I'm assuming whatever is on there is way out of date anyway.

I posted that on r/amd and mentioned that I find tempered glass windows stupid, which made a bunch of people angry.. oops

Now I need to buy some case fans, which are the best these days? I read that Corsair ML are on par with Noctua, is there anything else worth considering? I need 3 regular fans and a slim one, all 120mm PWM

I don't know if you've heard already, but those Raijintek cases have a huge problem with airflow. The PSU fan and exhaust fan both pull air away from the CPU. If you flip that exhaust you'll get cool air pulled in over your cpu, and maybe you pick up a magnetic dust filter and slap it on there. You can also open up your psu and flip the fan, but that voids your psu warrantee.

Maybe some *actual* movement on DRAM.

China’s economic regulator is paying close attention to a recent surge in the price of mobile phone storage chips and could look into possible price fixing by the firms that make them, a senior official told the state-run China Daily newspaper.

I think historically (well since the late 90's) speaking nearly every time we've had these simultaneous and dramatic DRAM price increases someone always gets busted for price fixing, gets a tap on the wrist, and prices go back down to sane levels for a couple of years or so before it all starts again.

Might as well if they're non-Chinese/South Korean and drive up the hardware price index in your country. Chinese regulators are always interesting, especially when it comes to gambling and lootboxes in games where they seem to give more of a poo poo than the FTC etc.

If anyone ever comes across actual evidence of foul play, the European Commission on Competition are really good at responding to reports fwiw. A fun way to learn a little about how things work, as long as you're not the kind of person to start a petition because a videogame had a girl in it or something.

Chipset drivers I always get as a matter of habit plus I wanted to take advantage of their customized power plan. Audio driver I ended getting out of necessity since I was having issues with audio not playing during rendered cut scenes in the Witcher 3 and installed them during troubleshooting.

What segfault issue?

This is interesting, though it's speculative and the technical details are way over my head: work is furiously but quietly underway to fix a hardware bug manifesting in vulnerability to a privilege escalation attack. The software fix involves a 5-30% performance penalty. All current Intel CPUs are affected. AMD processors are not affected.

Better details and discussion in the Intel thread (as is appropriate) but the implications in AMD land are interesting.

I can't see this doing anything to Intel in any actuality. I think of the FDIV bug recall, and they still made out like bandits that year.

Also, how badly do you want to kick Intel when you're partnering with them for the 8809G?

It isn't a company ending gently caress up for Intel, but it hurts them badly.

Losing performance and having a huge security problem sure isn't going to help them.

If EPYC can actually "For REALZ" launch AMD could easily pick up some volume from companies looking to make hedge their bets.

A 5-30% performance hit probably puts their IPC right back at Broadwell/Ryzen levels, doesn’t it? Zen+ might close up the gap by a lot more than expected just by virtue of getting clocks up.

 /*
- * User space process size. 47bits minus one guard page.  The guard
- * page is necessary on Intel CPUs: if a SYSCALL instruction is at

- * particular problem by preventing anything from being mapped
- * at the maximum canonical address.
+ * User space process size.  This is the first address outside the user range.

Wondering where the EPYC benchmarks are for comparison's sake, seeing as how, according to what Wiggly Wayne quoted, both Intel and AMD platforms are subject to the same workaround anyways.

Also, since I missed this article over New Year's: KVM Smokes VirtualBox On Initial AMD EPYC Linux Tests

Thank god that KVM stub implementation bug finally got squashed.

If I've read benchmarks right, 5-10% pushes them back to Broadwell. 30%... is almost as far back as Sandy Bridge?
