A (Dell) Precision replacement for our Intel NUC desktop

I didn’t really expect to be writing another build report so soon for my primary desktop. But in October of this year, it seemed to be time for a hardware revamping for my primary home desktop.

About five months ago, I built a 7th generation core i7 Intel NUC with Optane technology to replace an older 3rd generation desktop. That system ran a dual-core, quad-thread i7 processor, 32GB of DDR4 laptop memory, a 32GB Optane drive, and a 2TB solid state hybrid drive (SSHD).

Well, after three months I still felt the pain of a dual core system more than I’d expected. And in the meantime, my brother sent me a barebones Dell Precision Tower 7910 as an early birthday present. I was a bit concerned about it at first, since it uses Xeon v4 processors and DDR4 ECC registered memory, neither of which is inexpensive. The 1300 watt power supply had me concerned as well.

I decided it would be worth rebuilding the system anyway, since I could easily sell the system if I chose not to use it, and it’d be fun to run a more modern workstation for a while if I did decide to sell it. Spoiler: I am not planning to sell, but I’ll share the build report here so you can think about the options in case this meets your needs.

Curious Caveat

I had written most of this post, but when I went to confirm pricing, I realized that I’m running non-registered, non-ECC RAM in this system. Despite the documentation saying UDIMMs are not supported, and Crucial’s compatibility list showing all ECC Registered RAM, the parts I’m using are unbuffered non-ECC non-registered DDR4.

This may not be an optimal configuration, but if the cost and availability work better for you, it may be worth a try. Note that you will almost certainly be unable to mix registered and unregistered DIMMs, and you won’t be able to mix LRDIMMs and regular RDIMMS.

Update [2019-07-09]: I’ve noticed that the system has been sluggish, acting like it was swapping things out to disk even though I was only using about half of the total 32GB of RAM. Flashbacks to bad Solaris configurations in 2004. I replaced the unsupported memory described above with a set of four PC4-1700R Registered ECC DDR4 RDIMMs, and so far with a little bit of use it’s back to what I’d expect from a 28-core system with plenty of memory. Still using nearly half the RAM, with Chrome alone taking 6GB, but it’s snappy and not painful to use.

HSC Electronics will be halted early next year

Update: The HSC folks were out with a stand at the Electronics Flea Market in Sunnyvale this morning (March 9, 2019). Signs and flyers noted that they’ve sold the store to Excess Solutions of San Jose. Should be interesting to see how the inventory is integrated.

Update: HSC closed this past Saturday, January 12, 2019. There was an impressive crowd, cake and coffee, and last minute deals. Best wishes to the owners and employees for success in their next stages, whether retirement or different work.

About 8 months ago, I wrote about the closure of Weird Stuff Warehouse in Sunnyvale, California. Well, Halted Electronic Supply/Halted Specialties Company/HSC Electronic Supply will joining Weird Stuff in the history of Silicon Valley in just about 6 weeks.

Halted History

Halted has been in business for 54 years now. The Homebrew Computer Club often visited back in the day (including both Steves). I wasn’t around the Bay Area for most of that time, but got an introduction early in my time here, in the late 90s.

Around the turn of the century, Halted had three locations, with the main one being in Santa Clara on Ryder St, just off Central Expressway and Lawrence Expressway (near the Sunnyvale Frys, the pre-1996 Weird Stuff, St John’s Grill, and Ham Radio Outlet among others). Gradually the remote locations closed, and the Ryder store was left.

Halted was known for components of all sorts, books and magazines for people who made things from those components, antique radios, tools, legacy computer components, and all sorts of other things. It wouldn’t be unusual to find people in the store with ham radio transceivers on, students buying components for an electronics class, people reminiscing about the radios they used to listen to during the war, and random bargain hunters looking for computers and electronics to mess with at home.

They also had a well-known parking lot sale every September, where cases and crates and pallets would come out of the warehouse, hot dogs and donuts would be put out for sale, and you could get some incredible deals on things you’d forgotten you needed. And you could also find them at the Electronics Flea Market sometimes, with a truck full of carts from the store.

The New York Times had a feature on Halted in 2009, revealing and even foretelling the greatest strength and weakness of the business at that point. Continue reading

Experimenting with Intel Optane at home with the Intel NUC 7th Generation PC

Welcome back to rsts11 for the summer. We’ve got a lot to cover in the next few weeks.

I haven’t really done a build report in a while, so when I realized I was getting double-dinged for high power usage, I started looking around for ways to save power. One was my desktop PC, which while very nice (with 8 dimm slots and lots of features I don’t use), is using around 250-300W for a 3rd gen core i7 processor.

I decided, based on availability and curiosity, to build out a 7th gen Intel NUC (Next Unit of Computing) PC, which conveniently supports Intel Optane memory. You can read a lot about the Optane technology, but in this application it’s a turbo-charged cache for internal storage. The newer NUCs support it in place of a more conventional m.2/NVMe SSD (used alongside a 2.5″ SSD or HDD), and of course you can use it as an overpriced SSD if you don’t want to use the Optane software.

See my earlier post about an Intel NUC for use with VMware. That NUC is currently running Ubuntu and Splunk for training in the home lab.

I’ll take you through the build manifest and process, and then we’ll look at benchmarks for five configuration permutations.

Build manifest and current prices (July 6, 2018)

  • Intel NUC (NUC7i7BNH) tall mini PC, $450 at Amazon
  • (Optional: NUC kit with preinstalled 16GB Optane module, $489 at Amazon)
  • Intel Optane Memory flash module (16GB $34 – $39 at Amazon, 32GB $58 for Prime members or $72 otherwise at Amazon)
  • Crucial CT2K16G4SFD824A 32GB DDR4 memory kit is currently $310 (it was $172 when I bought it a year and a half ago, ouch).
  • HGST Travelstar 7K1000 1TB 7200rpm SATA drive is $57.
  • Seagate FireCuda 2TB SSHD is $92, with the 1TB version available for $60.
  • Keyboard, mouse, USB flash drive for Windows install, and living room television with HDMI were already in house, but if you’ve read this far, you probably have them and/or know how to choose them. After installation you can use a Logitech Unifying device or a Bluetooth device, but for installation I’d suggest a USB cabled device.
  • Windows 10 Professional can be had for $150 give or take. The actual software can be downloaded from Microsoft but you will need a license key if building a new system without entitlement.

You’re looking at about $1,000 for the full system at today’s prices. If you don’t need 32GB of RAM, stepping down to 16GB should save you at least $100. Continue reading

Weird Stuff Warehouse closed this weekend

I probably should’ve had more of a teaser title, but it’s still a bit of a shock, so you get the bottom line in the title. After 32 years, Weird Stuff Warehouse is closing this Sunday.

Updates at the end. This post has been updated multiple times since publication.

Also see the unfortunate news from Halted here: HSC Electronics will be halted early next year

If this is your first time here, please do take a look around. I’ve written about gear I’ve bought at WeirdStuff, but there’s a lot more here, from system builds and hardware, Psycho Overkill Home Office technology, and then there’s rsts11travel which breaks out my travel and related adventures and discoveries.

For techies who’ve lived in or heard of Silicon Valley anytime in the last 30 years, you probably already know Weird Stuff Warehouse very well.

Ars Technica wrote about them in 2013. The Six Fifty posted last year. Atlas Obscura got a post just last month apparently. You can see an archive of people’s Weird Stuff posts on Instagram here.

And over three decades after they opened up, serving businesses that wanted to get rid of no-longer-needed stuff as well as individuals who “needed” that stuff, Weird Stuff Warehouse is closing its doors at the end of business on Sunday, April 8, 2018. Continue reading

Getting Started with Cryptocurrency Mining – Building Your First Rig

This is a post I’ve started three or four times, with different aims and detail, but since I haven’t gotten it posted and people keep asking, I thought I’d start with a simple build plan and some caveats and considerations.

Where I refer to a ‘rig’ here, it’s simply a system dedicated to, or purposed for, mining cryptocurrency of some sort. It might be a single board computer, or a dedicated device, or a PC with one video card (or just a good cpu), or an open frame build with lots of GPUs and a beefy power supply.

Big Hairy Audacious Caveats

The numbers in this article, from prices to currency rates, are based on the time of writing (which may have been a while before the time of posting). They are not guaranteed to last even as long as it takes for this article to post. I am not advising on the value or prospects of any mining or cryptocurrency. You may gain money, lose money, or break even, or your entire city may sink into the ground like a big ole glowing gopher, if you engage in cryptocurrency mining on any level. Do so at your own risk.

Givens and Druthers

Two ODROID HC1 single board computers, next to a Transporter NAS device.

There are a lot of options out there, from multi-thousand-dollar ASIC miners for Bitcoin to sub-$50 single board computers that can mine Verium or the like. Your budget will determine a lot of the details of your rig, and your power cost may influence it as well. It’s also worth keeping family approval requirements in mind, since an Antminer may be noisy and generate a lot of heat, whereas a Raspberry Pi or ODROID might fit better behind something in your living room.

You can build a starter rig with one GPU, and depending on the GPU, you might be able to bring in $10-20 a week or more from that. Considering that you can do this with an existing PC and operating system, it may be an economical way to get your feet wet, and it won’t require messing with special power supplies, excessive cooling, or riser cards.

If you’re looking to impress people or make a lot of money, well, good luck. But you’ll be looking at open frame systems with riser cables or even multiplexers for PCIe. That’s beyond the scope of this post. Continue reading
