Review: Great CPU - My engineers love this CPU in their Solidworks Workstations. These CPUs are reliable compared to the previous generations that were overheating and crashing. These CPUs were paired with Asus ProArt Z890 Creator motherboards and 128GB of Ram. Super fast and stable for modeling work.
Review: This is the best read the review - Listen, this thing is a beast, there are no problems about over heating/ over voltage problems, you can overclock it but you have to water cool if you want to do that, it can game very well runs cod and anything you can throw at it , but for rendering and models and ai work, it is the best ngl those 24cores are the way to go don’t listen to those reviews it’s a great chip and is worth the money as along as you can get the supporting mods, it’s so impressive that is can run 4 sticks of ddr5 at 4000hrz crazy ngl

### ⭐⭐⭐⭐⭐ A step up in several ways from 13th/14th gen Intel
*by C***S on July 10, 2025*

I use this CPU in my gaming and video editing PC and it's honestly a step up from my 13th gen PC. Intel i9 CPUs have always run hot and the Core Ultra 9 is no exception. However, unlike the 13th/14th gen CPUs, you don't need a crazy cooling setup to keep it tamed under both light and heavy load(though for the sake of longevity I would still get at least a 360mm AIO or a 420mm AIO). Even a giant tower cooler like the Noctua NH-D15 Gen 2 will keep this CPU cooled properly. I don't do any heavy OCing, but the only high temps I see are during heavy rendering or compiling shaders for games(which this CPU does VERY quickly). I've used both the Core Ultra 7 and Core Ultra 9 CPUs and unless you really need the extra amount of horse power, the Core Ultra 7 is a better value than the Core Ultra 9. Stability is also easier to achieve on this CPU thanks to it's incredible memory controller. However, you really won't realize this unless you use RAM that has a clock driver in it(Known as CUDIMM), because if you're not you will not see the speeds intel claims you can hit, and if you can hit it, gets very unstable. Installation is straightforward and the same across 1200, 1700, and 1851 sockets so there isn't much to mess up. I'll say again; you will not see the high memory speeds unless you get a CUDIMM RAM kit. Conclusion: Basically only a small step down from the previous generation, but you get so much more stability and it is way easier to cool than the previous generations. Early reviewers made it sound like you were buying an i5 processor in a i9 branding, but man is it so misleading. This CPU absolutely performs like its previous powerhouse generation. BONUS: If you already have a LGA 1700 cooler you're in luck; you can reuse it on socket 1851! the socket dimensions are identical!
