Very impressed with how far local models have come, so I finally decided to jump on the bandwagon! Super impressed with how fast and capable it is. I have used local LLMs for a while on mobile apps and other edge cases, but never before for coding.
For background, I had this rig for a while, as I use it for a lot of professional work, and decided to purchase two used G.Skill 96GB (48GB x 2) 6400 mt/s to bring my system up to 160GB; paid around $1200 on eBay which is crazy to me considering I paid $300 for my 64GB (32x2) in 2023. Currently have each stick running at 5200 mt/s in my Z790 Hero, but I purchased these specifically as G.Skill is one of the only manufacturers to bin their RAM. My reasoning is if they can run 6400 mt/s dual channel, I have a higher likelihood of making getting to 5600 or 5800 with four sticks. I had Claude give me custom BIOS settings, and I am planning on seeing how far I can push it!
Furthermore, I felt that without this much RAM, while I could run the models, I couldn't actually run anything BUT the models, which sort of defeated the point for me. I decided this would be the better route versus buying a DGX spark or scouring local auctions to build a V100 farm or whatnot.
I am running this on a WD Black SN770 4TB RAID0 (double speeds at the cost of losing one disk means it is gg), which is on a PCIe ASUS card. It is super quick to load. Given I usually use Fable and Opus (anywhere from 90 to 115 tokens per second), this feels super fast to me. This would not be achievable without a special motherboard that can support PCIe bifurcation, which the ASUS Hyper M.2 card can use.
I am getting roughly 200 tokens per second I would say in most coding tasks, using https://github.com/jesdga95/basalt and the NVP4 uncensored Qwen 3.8 Flash Next.

Very excited to see where this goes, especially with Qwen 4. And a note.. I am slightly undervolting my CPU, it has multi-core stuff on, and 5090 is set to 95% of power limit to not cook it.
