Holy poo poo, fixing that cache clock stuff makes a huge difference. JFC. Take GTA5, parts of the city, the framerate dropped to 50 and sometimes less, now it's 70 and above.

Good to know. I know overclocking it doesn't matter, but it's one of those things like memory speed where you need enough and then it doesn't matter.

Is there something MS specifically calls out as being unsupported with installers? 16-bit compatibility exists through Win10 32-bit.

No, people just don't bother to install non-64 bit Vista/7/8/10.

Are there even generic 16 bit installers? That is from before MSI (or installshield/wisescript) was a thing. Wouldn't every 16 bit installer be a custom executable/script that installs the application? Should run fine on 32 bit windows.
E: Just remembered PIF files, but those haven't been supported in a long time.

InstallShield was first released in 1990, coinciding with the release of Windows 3.0 more or less, and there were several competitors too. And when Microsoft officially endorsed InstallShield for Windows 95 usage, it was often still a 16 bit installer until well into the 90s.

That said yeah they run fine on 32 bit Windows 10 just as on 32 bit XP.

Many old, old school 32bit installers still had a tiny 16bit portion that displayed a custom error window when you tried to install a 32bit app on Win 3.x
That little portion will make them hang up on modern systems.

I'm trying to think of why a layer below storage spaces direct is desirable.

Maybe never. They're almost certainly a small EPROM chip with a license key in there; Intel might be dumb, but they're not stupid. The bigger question is availability full stop: they were originally pointed as retail-channel add-ons, but they were basically never released and now might only come as part of OEM servers.

I still haven't seen a lot of evidence that they are notably superior to any other software-based RAID setup, though, so still wondering what the intended use case is for this thing.

I wonder how hard they would be to reverse engineer and duplicate - it seems like Intel's nearly asking for that if they're selling a platform that advertises locked capabilities but doesn't sell the key to unlock them.

Lends credence to the rumors that Intel may skip Cannon Lake completely for most markets. Now Intel just has to, you know, have a releasable 10nm process.

I assumed that there is potentially a reason for the feature to exist at all since I don't yet actually know anything about its performance (do you, or are you just being reflexively negative?) and I agree that the likely customer base is already aware of the existence of free software RAID solutions. It in fact doesn't seem totally crazy to me that Intel could come up with some kind of crazy CPU-based special sauce to improve performance when the storage volumes involved are directly attached to the CPU via PCIe lanes, but I'll freely admit that I don't know much about the fine technical details there and was just pondering in public.

Nope, it is actually just a soft-RAID program built into the processor. There is no special-sauce hardware, it is an x86 program that runs on the cores. The only advantages of this are (1) you can boot from your storage array, unlike soft-RAID, and (2) it doesn't consume a slot, unlike hardware RAID cards.

It's super niche.

Well, also it supports NVMe, which as I understand it no hardware RAID cards support yet. Intel is now shipping storage 1TB-8TB 2.5" NVMe drives, and if you want to run them in some type of RAID you sure as hell can't connect them to your old trusty LSI MegaRAID.

I was mostly curious about the nature of the DRM anyway, but I'm wondering more about the assertion that there's no unique benefit to the feature because it's all in software and implicitly equivalent to existing software RAID. It's well known that modern processors derive greater efficiency for many operations from breaking down assembly language into micro-operations internally instead of running the assembly code. Honest question - is it not possible that Intel would be able to add in extra code paths in their processors for RAID calculations which can benefit from working on a lower level than 3rd party code would have access to?

I know that for the bulk of the operations there's probably a public and fully optimized way of doing it (bitwise XOR is pretty standard stuff) but does that apply to the entirety of the feature?

Completely software RAID is displacing the hell out of hardware RAID anyways. A hyperconverged platform these days like a Nutanix box consists of multiple blades, each with their own storage hooked directly to their onboard SATA controllers, and all the redundancy is done alongside the replication in software. They boot off a little 64 GB flash module that plugs straight into a SATA port, the failure plan for which is "you call Nutanix and they send you a new one that you swap in and the blade will reconfigure itself from the backups on the other blades".

Intel could have made some money on this if they had gotten into it 15 years earlier, but proper software RAID is no longer a buggy mess and is becoming more and more commonplace even in the enterprise space.

It's possible, but they don't. As far as anyone can tell, the dongle basically tells the processor "present a virtual RAID controller to the PCI bus with features X, Y, and Z". Intel's OS driver interprets that as it needs to. I would be incredibly surprised if there were more going on in those dongles than that.

Yeah, ZFS is fantastic, mdadm is great, and all soft-RAID solutions prefer to just be handed drives directly.

I wish all processors could bifurcate PCIe down to x4 width so you could just use NVMe adapter sleds instead of needing the kind with a PLX switch built in. Forget Virtual RAID on CPU, I just want Virtual JBOD on CPU. :sigh:

They'll come out eventually, but probably not in the near future. If you need a system within the next 6 months (minimum), you're basically stuck with software/firmware workarounds like everyone else.

Spectre fix will take years. Meltdown has all ready been corrected in the OS by forcing cache purges during sys calls. There are optimizations in the later gen of chips to optimize this use case an minimize the performance impact. I wouldn't bother waiting, it will be a while.

The current-running assumption is that their answer was intentionally vague enough so that it covers the most likely scenario: that they've just incorporated the firmware patches into silicon, not that they've managed to re-engineer substantial chunks of the processor to fix the root problem.
