How to check if some RAM is low density memory since i bought 5 RAM's and they were probably high density so that was a reason why my PC didn't workG41 Chipset motherboards use low-density memory. Most memory manufacturers have discontinued making that kind of memory years ago.
You can still find it on eBay.
