Pros: Worked. Temps are okay. I ordered better thermal compound to see if that makes a difference.

Cons: I wanted to get the Prism cooler, but didn't want the higher power consumption. I now find the Prism is not available, and am now looking at water cooling.

Overall Review: I would recommend this cpu. I have had nothing but good experiences so far. I liked the lower power consumption compared to the 2700X. The performance delta is small.

Pros: Nice design, easy to install. I had seen comments about screw length; there were three sets of screws in my setup, varying in length by about 1mm each (so, three different lengths). I bought the Xl120 along with a cooler master case, making the assumption that the two might be a designed together match. The cooler easily mounted to the case and the cooler was simple to affix to the CPU. The position of the CPU on ASUS P8Z77-V LK mboard made installation east.

Cons: But, the mboard wouldn't post. After a lot of troubleshooting, I found that one of the cooler's standoffs (a good solid hunk of metal) had scored the motherboard under the standoff and was grounding to the motherboard. No post. I hadn't gorilla'ed it (I thought) as they were just a bit over finger tight, but did find one of the standoffs had a very rough, scored surface. This was the likely problem. Removing the standoffs and using the stock Intel cooling fan permitted post, boot, and it all worked well after that. I ordered 4 insulators (.25mm) to fit between the standoffs and the motherboard. When I get them I will reinstall the XL120.

Overall Review: So, why 3 eggs? The cooler's design looks well done, and it fit together very well with the cooler master case. The mounting scheme for the cooler to the cpu is clean as well. This design has promise. If it fails to live up to this promise, I will report it If it works well when Installed, I will report that. Watch out for standoffs with rough surfaces that can score the mboard.

Pros: I ordered yesterday, got them about two hours ago. They were not on the MB compatibility list, but not much is. So I took a chance. I had been using 16GB Gskill royal 3600, but wanted to gift them to my niece. She is a geek AND liked how they looked. Plus I wanted all four slots filled, as it seems to make a difference per Steve. Installed them, they came up okay but wrong speed, so I rebooted and they had corrected speed and voltage on its own. Perfect. Seconds to reboot. They look good (not going to use IQ cuz) and worked. Perfectly. MB is Aorus X570 Xtreme earliest version. CPU is 3950 from Silicon Lottery (love SL). GPU is EVGA 2080 ti Kingpin. Water cooled 3950, have water block for KP but not needed so far. Looking longingly at 6900XT. This system is great and painless.

Cons: Nothing. When everything works perfectly out of the box, no cons.

Overall Review: I would recommend this system. Fast and painless. I also have a new Aorus Master for niece. We'll see how that goes. Aorus stuff has been solid for me.

Overall Review: I would buy this again if I had a similar need.

Pros: The build quality is the best I have ever seen. I am waiting for the 3950X (and probably a month or two after it is available to let bios's settle down). I am very impressed Asrock.

Cons: The first M.2 looks like it is under the cooling mass. This is the M.2 that is connected to the cpu. Placement there 'mayne' for cooling, but awkward. I should mention that this board is heavy, but that is both a pro (thermal mass) and a con (just heavy).

Overall Review: Not running yet. This build will be great, so planning a lot.

Pros: It came up no problem, but I expected better performance. Maybe XMP is immature? I have an Aorus Xtreme motherboard (with a 3800X that hits 4.5 on 6 oF 8 cores w/o PBO) which has been just excellent, but this is new DRAM.

Cons: it wasn't as good as the Skill CL16 Royal. 210 points slower, which is a lot, and it is CL14. The board kept trying to make it CL17. XMP I am thinking.

Overall Review: It's okay. I might return it and wait for the bios to catch up. Gskill, any input here? You know better than I do.
