  • Starlink provides service to areas where fiber is impossible. Like the middle of the ocean and actual rural areas where fiber runs could be tens of miles or more between homes. Those are area where no one will build out fiber unless the homeowner is paying for it themselves, the various government programs would never cover those actual rural areas despite what they claim. At best they might cover city outskirts for new infrastructure, where fiber nodes are already relatively close by. They’re never adding fiber to existing rural farms and ranches.

    They are not a 1:1 service comparison. You would need to compare It to other satellite providers, and there isn’t a comparison because all of those are dogshit in comparison to Starlink.

    There’s a reason it’s as popular as it is so quickly despite satellite internet in general not being new. The low earth satellite constellation means a massive difference in capability compared to conventional geostationary satellites. Multiple second latency, slow downloads nowhere near advertised double digit Mbps speeds, single digit Mbps upload speeds and often monthly data limits as low as 50GB per month are what the conventional satellite providers offer.








  • Similar issues even with just 2 DIMMs with some XMP/EXPO profiles not working on AMD systems because of board/CPU limits. It should technically work, but for whatever reason it just can’t handle it and speeds need to be dropped or the timings loosened a bit even though the RMA itself is rated for that.

    Not that the higher speeds are even necessary for 90% of users outside extreme overclocking. DDR5 6000 is basically where you reach diminishing returns anyway, and that’s often where that limit seems to appear.


  • Yeah AMD’s memory controllers, especially DDR5 seem to have a lot more difficulty at high speed with 4 slots filled. I used to plan upgrades around populating 2 slots and doubling if needed a few years later, instead now you really need to plan to ignore those slots if you are needing memory performance for things like gaming versus raw capacity.


  • Dug into it, got into Memtest’s source code and discovered that the first pass is shorter on purpose so that it quickly flags obviously bad RAM. Apparently if you want to detect less obvious issues, you have to run multiple passes.

    I thought it was common knowledge that Memtest needed to be run for multiple passes to truly verify there are no issues. Seems that’s one of those things that stopped being passed down in the community over the years. Back when I was first learning about overclocking around 2005 that was emphasized HEAVILY, with the recommendation to run it at least overnight, and a minimum of 10 passes.
