What's new

AMD 7950x is impressive, many thanks to Guy Rowland and Pictus for the inspiration!

Just when I had settled on saving up for a new Mac later this year when the M3 Max and Ultra Mac Studios are released, I stumble across Guy Rowland's thoughtful thread about building his AMD PC.

I have a 12 year old gaming rig that was top quality back then (i7-3770k, Gigabyte Z77 motherboard, GTX 680 graphics card, G.Skill Ripjaws memory, Corsair SSD and 600T case, OCZ 850 power supply) that has been absolutely rock solid over the years. It has been a VEPro slave most recently but struggling mightily with Cinematic Studio libraries and with the CPU intensive plugins I've tried to use. My main music computer has been a 5 year old 16gb MacBook Pro to run Cubase and Logic, and over the pandemic I added a 2018 i7 Mac Mini that I upgraded to 64gb. I was content with these until I started to use deeply sampled libraries with multiple mic positions and adding convolution reverbs. The final straw was getting Rico Derk's Project Colossal which brought all 3 computers to their knees. The combination of parallel effects processing, multiple mics with complex Kontakt scripting, and mastering plugins was just too much for these processors to playback in realtime without significant compromise. My VEPro instances were regularly spiking and glitching (I'm looking at you Cinematic Studio Woodwinds). I was bummed that a total of 16 cores and 112 gb over 3 machines could get swamped by what I was throwing at them.

I have learned so much in the past 2 weeks by reading through Guy's thread and Pictus's recommendations. I learned that nowadays, memory is really secondary to processor speed (a single overloaded core can cripple a project), there are other bottlenecks that have nothing to do with the number of cores, and you don't need the absolute fastest SSDs to stream samples since Kontakt can only load them at a certain pace anyway. I went down the rabbit hole of researching power efficiency, air vs liquid cooling, AM5 pros and cons, dual channel DDR5 limitations, XMP, underclocking, PCI4 vs PCI5 SSDs. It has been a lot of fun actually, I haven't nerded out like this in a while.

Anyway, I put my oldie but goodie PC components to use and rather than spending 3-4k for a tricked out Mac Studio, I upgraded to this:


(AMD 7950x, ASRock Taichi Lite B650e motherboard, Thermalright Phantom Spirit cooler, 96gb G.Skill 6400 DDR5, Crucial T500 2gb m.2 SSD)

$1300 and I now have a new top of the line music PC.

It is amazingly fast. Where 3 computers were getting hammered with instances constantly 80-100% maxed and cracking, I have yet to break 50% on even the most plugin heavy, multiple mic instance in VEPro, and it would be much lower with a more normal template. And this is running it in the 105W ECO mode! I have had zero problems with the BIOS or posting (the memory runs at 6400 as advertised). I get it now. Macs are wonderful and I will continue to use them, but PCs represent so much value.

Thanks Guy for doing all the build research that I piggybacked on and to Pictus for providing so much info about the AM5 platform in these threads. Team Red or Team Blue, it doesn't matter, this a great time to be building computers.
 
I feel like a very nerdy rock star - don't think my name has ever been in a forum thread before and I'm all giddy.

Very happy with my rig so far too, just the humble 7900 with no X. Had no peformance issues anywhere, and it's very low powered.

Last year, in a feeble attempt to cheat death a little longer, I'd taken to doing 20 press ups while my computer booted every day. By the time I'd collapsed exhausted into the chair, the thing had just started to think about playing the Windows 10 startup sound, and I then had a bit longer to recover while it populated everything.

With the new rig, the Windows 11 bongs sometimes start when I'm at 5.

Good to hear your performance is so good at 105w. One thing I never really learned is whether or not idle and low powered chores in Eco mode are the same watts as the normal high powered mode.

Happy composing, jazzbozo.

I'm glad everything went well! :2thumbs:
6400MHz 2x48GB CL 32 is fast for AMD.
Please, post a screenshot from Zentimings.


Test the RAM/memory controller, use 3 cycles of y-cruncher tests 14/15/16.

-Type 1 + enter
-Type 8 + enter
-Type 14 + enter
-Type 15 + enter
-Type 16 + enter
-Type 0 + enter

BTW, new chipset driver version 6.01.25.342
https://www.amd.com/en/support/chipsets/amd-socket-am5/b650e
- First create a system restore point
- Uninstall the current driver (no problem if not possible to uninstall)
- Install the new driver

For anyone reading, some good tweaks for AMD/Intel/NVIDIA at

Thanks for the link. I'm building a new computer soon -- keeping some parts like 5900x and graphics card but switching from itx motherboard to matx to take advantage of 128 GB. Trying to do all my composing on one computer.

Sure thing (I stopped the y-crunch after 5 iterations)! I chose this RAM because it is what Game Tech Reviews on YouTube used to get his 7950x to 192gb at 6000mHz. It's running the XMP profile.
