 2021 06 18                        BOX and COOLING

My computers need names, to reduce the confusion:

  • STIRLING 2021 - Built last February, currently running a Ryzen 9 3950X CPU. Stirling is a lovely town in Scotland where my beloved and I stayed overnight on a 2nd honeymoon trip some years back. Three Stirling computers have been built so far, but only Stirling 2021 exists here now. One failed, and another is put to good use elsewhere.
  • FORTE - The computer we're building now. The word origin is probably French, meaning "strong point." Usage and pronunciation may be influenced by Italian, as in music. Pronounced for-tay in my office, accent on "for," it is simply the name of my next computer.

So far we have decided on these components:

  • CPU: AMD Ryzen 9 5950X CPU, 16 cores & 32 threads, $799.00 Amazon, two on order, one due very soon, one in July.
  • Motherboard: ASUS ROG Crosshair VIII Dark Hero, PCIe 4.0 and more, $449.00 Amazon, ordered for delivery Wed, Jun 23.
  • Windows 10 Professional, FPP, box pack, full version, USB. Not yet ordered. Some are available for $99, but that price seems low and I'm suspicious that it might be a knockoff. I want the real thing from Microsoft.

The AMD Ryzen 9 5950X CPU which is arriving soon could be used in either Stirling 2021 or the new Forte. We'll see. It depends a little on how soon the second one arrives. It's on order too.

A "be quiet" brand BK022 Dark Rock Pro 250W TDP CPU cooler (air, not liquid) was ordered and has arrived. $89.90 from Amazon. It remains to be seen whether that will fit on the selected motherboard in the selected case above/beside the selected memory cards. It's a big honker, weighs 2.4 pounds, and will sit directly atop the 5950X CPU. 

It came with a second fan, not attached but attachable. I'm still a little confused about where the loose fan should mount. There's a space right in the middle of the cooler - the image shows a fan there. Should the loose fan go there? If so, why wasn't it mounted there at the factory? If there's room, should I add a third fan on the back, pulling air rather than pushing? Why not?

Phanteks Enthoo
Pro PH-ES614PTG_BK
The case will be the same as the one used in the Stirling 2021 computer, the Phanteks Enthoo Pro "PH-ES614PTG_BK" ATX Case with tempered glass side panel and integrated RGB (LED) lighting. Ordered from eBay (Newegg store), $109.99, shipped yesterday, should arrive in a week. Size HWD 21.1 x 9.4 x 21.7 inches. The glass side panel is one whole side of the case, so you get a spectacular view of the innards, taking full advantage of any RGB inside. And for other reasons as well, I really like this inexpensive but full-featured case. 

The case has three bays for optical (CD/DVD/BD) drives, and I'm still a believer in optical discs. Many of us still have a library of movies or games on CDs, DVDs, or BDs that can be played on the computer. You can still buy "My Cousin Vinnie" on DVD or BD from Amazon.

Full case with lots of RGB

Much more important, we write some of our backups on Blu-ray M-Discs because they are a genuine archival medium. An M-Disc in a bank vault will last longer than the bank. Even in our own fire-resistant safe they will probably last far longer than anyone now alive, and longer than we will have computers and drives capable of reading them, if they don't fall prey to some risk other than simple deterioration. See the previous post about risks (theft, fire, flood, etc.).

New laptops are too thin to have disc drives these days. USB flash drives are not archival. So it's just a good idea to have a highly competent computer around that can still read and write CDs, DVDs, and BDs. A good LG drive which will do all of that costs $74.99 at Amazon and hooks directly into a standard SATA port on the motherboard. I have two here in Stirling (and can write two backup BDs at once), but Forte can get along with just one. It's easy to add another. One drive is on order.

2021 06 16                                                      SECURITY 
OK So far the new computer will have: 
  • CPU: AMD Ryzen 9 5950X CPU, 16 cores & 32 threads 
  • Motherboard: ASUS ROG Crosshair VIII Dark Hero, PCIe 4.0 and more 
  • Windows 10 Pro, full version, USB 
  

But first some words about security: BitLocker is Microsoft's full-disk encryption facility, and it works. The computer must be and will be BitLocker compatible. It turns out that BitLocker has almost no impact on performance, even gaming performance, so that's not a downside. I think that the the mobo (motherboard) should probably have a header for a TPM (Trusted Platform Module), and the "Dark Hero" does. I'm not certain about actually using a TPM though, because I think that the CPU or the firmware may also provide the necessary BitLocker functions. If so, the separate TPM module would not be necessary. In fact, last I looked, new ones with the right updates were kind of hard to find. On a previous computer I enabled BitLocker with a tiny USB flash drive and no TPM. Important point: Even if the mobo is compatible and everything is in place, BitLocker doesn't have to be enabled. 
 
If you're not a BitLocker (or Microsoft) fan, or you don't have the Professional version of Windows, an excellent alternative is VeraCrypt, an open-source and thoroughly-audited facility which has both a full-disk encryption mode and a file-encryption mode. In fact, the best security may be found with a combination, where BitLocker is used to encrypt the whole disk, and the most precious individual files are further encrypted with VeraCrypt. Examples: A lawyer's client files, an engineering company's proprietary designs, the computer owner's social security numbers, bank accounts, and website logon passwords. I do use both BitLocker and VeraCrypt, plus several more. 
 
Please do not use the same password for BitLocker and VeraCrypt, or for anything else. That would entirely defeat the additional security. That's what a password vault is for, and there are some very good free ones.
 
In addition to BitLocker and VeraCrypt, there are other very useful encryption facilities. For example, I use Macrium Reflect to back up entire disk drives, and those output files can be encrypted. I'm sure that some of the competitive backup facilities can do the same. There is also a free and widely-used zipping app called 7Zip which is better than the Windows zipper in several ways, especially because its zipped output files can be encrypted. Here is a partial list of a few handy encrypting apps:
  • BitLocker (requires Windows 10 Pro) 
  • VeraCrypt (replaces TrueCrypt) 
  • 7Zip 
  • Macrium Reflect (or competitors) 
  • KeePass (password vault, or competitors) 
  • EFS (Windows "encrypting file system") 
  • Lots more ... 
Macrium Reflect
Please PLEASE do not lose your BitLocker keys! Or your VeraCrypt passwords or PIMs, or any other encryption keys. There is likely no recovery except for your backups, and only then if the backups are UNencrypted or you know THEIR keys. Losing the keys is the same as a disk crash. Obviously, it's not a clever plan to keep the only copy of your encryption keys WITHIN the encrypted files. Please please write the keys on paper, or in a file within an UNencrypted DVD or flash drive, and keep that in a safe place, like a bank safe deposit box or your best friend's top dresser drawer, several miles away. Note: If you have more than one disk, you will have more than one key. You must save all of them. 

No matter what you think, the keys are not safe in the residence (or office) where the computer is located. Period.
 
Here is an only-slightly tongue-in-cheek list of risks to keeping the keys in the residence: Theft, computer virus, ransomware, fire, flood, lightning, hurricane, tornado, sinkhole, earthquake, termites, C-drive failure, other drive failure, smoked motherboard, smoked CPU, BitLocker failure, other encryption failure, Covid-19, another pandemic, asteroid impact, ultra-Plinean volcanic eruption, lunar cataclysm, black hole consuming the earth, gamma-ray burst, nuclear explosions, coronal mass ejection, sun going nova, or bad luck. 
 
The point is: Some of these could actually happen, and some WILL happen to some people who don't have their keys. Please don't be one of those. My residence is not safe, and neither is yours.
 
There is no rule against keeping the keys in multiple places. It's a really good idea. 

Backup is even (far) more important than encryption, and we have said little about it here. There is much more to be said about security, but saved for another time. 

The next post will get back to building a computer.

2021 06 13

What computer shall I build this time? I'm a retired guy with an appreciation for excellence and (maybe) enough budget to do excellence. My computer experience started in 1962 with the University's Control Data 1604 using a magnetic tape operating system. Indeed, even though that computer cost a million dollars, disk was still a dream. My how times have changed.


I'm going to make (another) very hot, dual-purpose, world-class (if consumer-grade) Windows 10 desktop computer.

New Computer with RGB (LED) Fans

Last February, 2021, I fired up a really nice new homebuilt desktop computer with an AMD Ryzen 9 3950X CPU, the gamey little brother of the Ryzen 9 5950X CPU, which is is arguably the hottest silicon on today's market. Both CPUs sport 16 cores and 32 threads with speeds that make them appropriate for BOTH gaming and content creation. At the time, I bought the 3950X instead of the 5950X to avoid scalper's prices and sellers with odious reputations. That computer is working very well, thank you, but perhaps I'll upgrade to the 5950X soon anyway. The ASUS mobo and everything else will support the big brother.

Now I want to build another new computer just because it's fun to build hot computers. I don't really have any use for it yet - perhaps I'll sell it, or use it and sell the first one. Cost is an issue, but performance is a bigger one. Here are some features that are already pretty much decided:

Processor: AMD Ryzen 9 5950X. I'll get one somewhere, maybe two. Prices are coming down and the sellers are looking more reliable. In fact, BREAKING NEWS, last week (June 5, 2021) Amazon was selling these from their own warehouse to prime members, with 3-week delivery, at the AMD list price of $799. Today they aren't, though. Sigh. Guess I should have snagged one when I could have. Yep. 

More BREAKING NEWS - I just ordered one from Amazon Prime with delivery in July. $799.00 Sold by Amazon, shipped by Amazon. And just now I hear that delivery will be in June after all. I like Amazon.

ASUS ROG Crosshair VIII Dark Hero,

Motherboard: ASUS ROG, X570, exact model to be determined. TUF? STRIX? Crosshair? What kind of a name is "Crosshair" anyway? (oh, it's a rifle sight). Or "Strix" for that matter (a mythical bird of ill omen). I choose ASUS only because I have some experience with ASUS. Most of that experience is good, though not all. Is there a better mobo? Comments invited. Maybe this isn't so very decided after all. Having done some searching, I'd probably choose the same board that I bought before, the ASUS ROG Crosshair VIII Hero, though I was advised online not to waste my money on "that brick." 

Looking further, however, I'm now attracted to the newer ASUS ROG Crosshair VIII "Dark Hero" mobo. It's more expensive yet, but has every feature of the plain ordinary brick plus Wi-Fi, and seems somehow simpler and more straightforward. In particular, it doesn't seem to need its own fan to cool the X570 chips. It's just cool all by itself. $433.89. BLT (ShopBit.com).

More coming soon ...
