Hello everyone. New member here. Name is Luis. I have experience building my own pcs, and a couple that I built for a friend. I decided to join recently because I have never had problems building a pc until now. I am disabled and can't use my left arm so it takes me longer to build a pc and I only build my own since the injury, and when I can.
About 3 months ago I decided to upgrade my pc, had an Asus X99-A mobo with an i9 9900k cpu with 64 gigs of ddr4 ram and 4 months ago I installed on it a Geforce 4090 and a 15tb intel pcie SSD, which are much faster for gaming than sata SDDs. If you can buy one you should try it. They are incredibly fast for games.
Anyway, 3 months ago I bought an Asus Maximus Z790 Extreme, an i9 13900k, 2 sets of DDR5 sticks,( I always buy 2 sets just in case one set is bad) and a new corsair h150i elite lcd cooler. I had an older cooler, but the exact same one. With either cooler the mobo could not dissipate heat from the cpu, and before it would crash I was able to get it to run for a bit and also gave me memory errors. I alsoadded the same SSD drives, an hdd drive for documents and the 4090 gpu the older system had. The mobo or cpu could not find 2 dimm slots, and the third one would cause a loop in the error code phase. Only the ram in the B2 slot was recognized.
I returned that mobo and bought another one, brand new. It arrived with the plastic piece that is right on top of the q-code led. I still installed it to see if it had the same problems as the first one. Although this one had no problem dissipating the heat from the cpu it still gave me memory errors. Again 2 of the dimm slots were not recognized and I could only get it to be partially stable with just one stick of ram in the B2 slot. i returned that mobo as well and decided to try a Maximus Z790 hero. But this one is also having the same problems with memory. i came here to see if anyone was able to find what is wrong and if anyone has been lucky enough to solve these memory errors. So far it seems lots of people are having these same problems.
