I had a substantial Solaris install base, and MS was trying to talk me into going to Server NT. You and several of your team members were doing dog and pony for a group of us customers. We had a long and interesting discussion about wolf pack clustering.

I just upgraded my FX6350 to a Ryzen 5 2400G (32GB ram) and NVMe drive. Faster and uses less electricity at peak than my old system at idle, so will pay for itself. Must say the leap from SATA to NVMe is amazing, even with SATA SSD, it's just wow. I look forward to owning one of these HP systems in....7-10 years time when they are affordable third-hand budget to me.

So there will always be some meat left on the bone with those, but that makes them more robust lifewise and why second-hand if they ain't broke by now, fair game consideration for those budgets.

At the moment a 5700U is much better value for money, and comes with a faster integrated GPU to boot.

My guess as to the problem is that you are bandwidth limited, and are hitting increased core-to-core latency, and have saturated the shared L3 cache, which will grow worse when adding more memory.

Interesting video Dave, as always! Hey I was thinking, how about if you create a video talking about your journey through different compilers: how the compilers for windows work(ed) vs the compilers for mainstream use, how they evolved during your years in Microsoft, compile times for big large projects in the past vs now, which ones you like/dislike the most and what you use and like today... I think a video like that would be great!

It's actually been years since I have watched a video dedicated to the top-of-the-line new PC -- You did not disappoint! Thanks for the fun show-and-tell for this awesome machine. I am one of those users who rides the back of the tech wave, building my PC's out of parts that local shops and friends have lying around just before they go to the recycle shop. I am running Nobara Linux on an old 4th gen i5, and looking at upgrading to an i7 next year 🙂 Legacy gaming is my favorite use of the old PC's I have. I wish you the best in your exploits and endeavors in software development.

Fantastic work as always. Thanks for such wonderful content Dave!

I love all the vintage tech you have collected. Like that land-line telephone, it's good to see someone is still preserving this technology.

What a beast of a machine, Dave! Very tempted to look into a Threadripper for my next build even if I don't code compile like you do.

Were your 8 x 5600 sticks running at 5600? Or, did they fall back to base clock at 4800? Most memory kits I've seen don't have EXPO profiles yet, with the exception of some G.Skill and Kingston RDIMMs. That said, I know some Sapphire Rapids kits should technically work with TR 7000, even without EXPO, but haven't been able to do any testing yet.

Great video. Amazing processing chip. I think building one of those rocket sleds in your thumbnail pic would be great fun too ... Cheers ...

Hi Dave, great demonstration and explanation of the new system. It's a bit more than I would ever need, but it's great to get this info from you. See you next time. Take care!

Also be aware that the HP workstation might not support XMP profiles and defaults to the fastest JDEC profile. Because of the increased voltage in XMP profiles, they are essentially letting your BIOS automatically overclock your memory. I ran into his problem with an HP Z2 workstation with an i7 10700k where I upgraded the memory and noticed it clocking according to the fastest JDEC profile instead of the XMP profile. There's no way to change this anywhere from BIOS or software.

Maybe more RAM doesn't help if you already had hit the bandwidth bottleneck to the RAM. Anyway, impressive compile performance. I was reminded by when I got my hands on a SGI Onyx for the first time and tried to compile stuff. Instead on spending ~10 sec per file as my PC would need at that time, it was more like 10 files per sec instead. I was blown away. But now 30 years later, if Moore still applies, things should be log2(15) or about 32,000 times faster.

The god of LED's right here!

matching ddr5 modules is a gamble. I think even if they are individually rated for certain timings, they might have problems when you use more of them together, I have had the same experience as you but relaxing the timings helped. I don't know why it straight out doesn't crash, maybe the on die ECC has something to do with it?

Dave, Great video as always. Fan of the task manager from NT3.1-4(always open) you know! Studied electric engineering- just built a 24C/32T I9 13900K-W/RT4080-128GB (before I7-6600K) big jump- in the process of building another WS w/AMD 7950X3D 16C/32T - for ML (Bible study - Ancient Hebrew code)

It is great to see you review this :). I feel strange as I ditched the HEDT platform for the first time since the x58 days in exchange for a consumer grade system. But for me I am drifting away from a super system that does everything to a mix of servers and consumer equipment that is tailored for each task. My two servers both hold 96cores/192threads and a TB of ram while my "main rig" holds a mere 16cores/32threads and 64gigs of ram. So all my renders are run on a server now and my gaming lives of the consumer system. Part of me misses the do anything nature of the threadripper system but the rational part says I built a faster gaming system for a tenth of the cost.

Merry Christmas Dave ✌️

To me the chromium test seems to indicate that no matter how much muscle you throw at it you've passed a process efficiency limit, which is no the case for example with 3d rendering where you can split in chunks the task easily. Maybe using 2 vms with that platform for compiling purposes (linux and windows versions in parallel?) would probably get more stuff done faster.

@SeanBZA

Yes likely running 4 concurrent versions of Windows, with each hitting 256 chromium windows will work, as that will at least move the bottleneck from the Windows screen display to another point, likely memory bandwidth, or just the bandwidth to communicate with the graphics system alone. At least should be easy to do, given the 128G base, and split it into 4 31G VM's and 4G for the hypervisor, and 4 separate displays on the video side.

What an awesome content! Benchmark baseline for future references!

Hi Dave. Do you have a page or anything where you upload your different LED projects? I do electronic repairs (PS, Xbox etc.) and am interested in learning projects like that, but would be nice to have a decent page to reference from someone who takes pride in their projects, like you do :)

Do you happen to have captured the wattage to the power supply, for some of your scenarios? There is a subset of your audience whose interests include various efficiencies.

Bad ass machine! Thanks Dave!

Hi Dave! Love your channel. Would you be open to taking custom benchmarks from fans? Wouldn’t have the project ready until next month, so you’d have some time to think about it.

@Dave's Garage Did the computer come with open ram slots? ddr5 runs slower when fully populated by a significant margin. For example, my motherboard has four slots but if i use all four of them, the speed froms from 5200 to 4200. Ryzens are incredibly dependent on memory bandwidth so that might be the issue. You might also consider you have 96 actual cores no 192 so using hyperthreading when you're maxing out a core anyway will simply slow it down. I would expect your absolute fastest result would be testing 96 instances.

I like the choice of a plasma display for the 'neon' sign.

The time difference could be a difference in tertiary timing between the kits. If you didn't validate ALL the timing of both sets of installed memory then it's impossible to say they were the "same". The time difference is a little less than 3% if my math is correct which could be explained by that. Next when I'm looking at the compiles taking place I'm looking at the number of tasks running, where numbers are simply flashing very fast but both seem to be about the same. If the compiler allows for 192 threads I don't understand why that would be the same, so is it possible you hit a limit in some software when you were compiling?

Dave could you please tell me what some of your display lights are. You have so many cool lights and im a lava lamp/cool light stuff type of dude. Thanks for the amazing vids

Can you bench mark LLama 70 B and Falcon 180 B maybe 4 bit quants on cpu ? it may saturate the 8 channel memory. To use oobabooga textgen web ui is simple to install and use.

Hey Dave, noticed you added some modified car lingo - are you an enthusiast? Would love to see a video if you have any project cars/forever cars you own.

I’m interested in a large CFD, NASTRAN, etc., large matrix oriented engineering problem or a large wireframe animation problem??

I have an old PC running the latest Debian release and shell only it barely runs ``cmatrix`` at approximately 5 frames (?) per second. It's an Athlon 1GHz from around my birth year. Most of the caps are are bloated, although none burst yet and they still work. I will build my next workstation in the MASSIVE steel tower it's in. I'll have to modify the front panel to allow for some stealthy air intakes. Ideally I would like to put a USB 3.5" floppy drive inside but I'll have to see if I can fit that behind the front panel. I do have a USB 1.0 PCIe card that has an internal standard female connector (not a header, a proper connector), so that should work. Since the front IO is at 1999-2001 standards I'll probably have to use a USB-c dock connected to the rear IO for any high-speed-IO, but it will look really nice. The best part is that it has no rust anywhere despite it's age and less than perfect storage conditions.

"Somewhere Between Yes With A Butt And No With A Unless" That Line Is Gold.

Were the replacement RAM sticks the same CAS latency? Do they have XMPP/is it on? Finally, is Fritz the one I know who was in TwC and went to ZDI?

The main reason memory speed drops when all slots are filled is that the doubled I/O buss loads require more time for the transmitter outputs to charge/discharge the lines. My source: read any motherboard manual.

I once saw a video where you talked about your home network. Do you have your equipment list? Could you do a video a top-notch home network?

I love my Z servers. I’ve got a dual Xeon and it’s awesome. Great value when buying older machines.

From an end-user perspective, the HP Z-class workstations are OUTSTANDING! Very well built; the airflow pathing is well intentioned, and service is a dream with a near tool-less chassis. Of course that comes at the sacrifice of weight: the chassis is HEAVY, and somewhat cumbersome. The Z6 chassis is doable by a single person, though the Z8 dual-socket workstation is more easily carried by two people. These are effectively servers in a desktop chassis, and should be able to handle any workload thrown at them.. as long as you can suffer the price :)

As the previous guys stated. it sounds like it might be a bandwidth isssue with the memory and might be overloading the memory controler on the cpu ....increasing voltatage to the memory as well as the cpu package might give better numbers ? but i would assume you would have noticed that ....just figured i'd throw it out there. thanks

Is the ram somehow blocking itself? If you have 128GB on 8 slots its 16GB per slot. 384 is 48GB per slot. Does some of the RAM access have to wait for time on the pins?

Your "old" PC is by no means outdated. 3 years is not old. By most people's standards, that is still considered a modern, high end and very powerful productivity desktop. If I had that PC at home (or at work even), I honestly wouldn't know what to do with that much power. I'm not being judgmental, it's just interesting to hear specs like that being kind of classified as old or venerable. My main driver at home is still running a Haswell generation CPU and GTX 970 🤣 Anyway, love the channel and I find a lot of your video topics to be informative and different than the content I see on a lot of other tech channels. Keep them coming.

The motherboard setup could possibly be like some other server hardware I have used when it comes to memory. They will be rated to run x speed up to a certain capacity or number of DIMM slots used. Once you start populating the rest of the DIMM slots the memory speed will slow down by a bit to help with memory controller stress.

1. Take care with overclocking of new AMD CPU's. The last non-Threadripper generation is (was) very intollerant for to much voltage. There was melting of CPU die's and cavities in the silicone of AMD 7xxx CPUs. Don't know if this also applies to Threadrippers. It seamed to be connected with the heat transfer method's inside the die. 2. maybe a sorting algorithm is a bottleneck during compilation? changing a sorting algorithm had significant impact on boot time in freebsd 14.0.

The fact your compile was slower with later memory sticks is a coincidence with something I saw about a month ago recommending laptop users to not go above 16GB memory per stick because they claim it would actually be slower. This tells me the bottleneck isn't in the memory or the motherboard, but the internal memory management. Something about the architecture isn't keeping up with the size of memory. Is some kind of hardware swapping happening perhaps?
