I’m having a very odd issue. I have an ASUS X99-E WS motherboard. I recently purchased 4 sticks of DDR4 Corsair Vengeance RGB pro RAM 3600 MHz, with each stick being 16GB.
I previously had 2 sticks of DDR4 HyperX Fury Black 2133MHz, with each stick being 8GB. These were plugged into DIMM slots C2 and C1. The manual recommends D1 and B1, however these are awkward to reach on my computer (though not impossible) so I just used C2 and C1, and both were detected and worked correctly for the past ~4 years.
I removed these old sticks and plugged in the new RAM into slots C2,C1,A2,A1. However, the computer did not boot. All the fans started and the hard drive were running, but the computer did not give any output to the monitor, and usually when my computer runs correctly the fans start at full speed then after a few seconds they slow down, whereas now the fans went to full speed and stayed at full speed. All the RAM sticks were getting power as the lights on them were on.
The motherboard gave error code 53 which means “Memory initialization error. No usable memory detected”
I then uninstalled all the RAM except for one stick and tested it in every slot and had the same problem with every slot. I pressed the MemOK! button when testing each slot as this is supposed to test different parameters for the RAM until it successfully boots, but this did not help anything.
I then tried different sticks in random slots (only one at a time), and nothing worked. (I did not try every stick in every slot as this would take all day, but I tried enough that I’m confident no stick works in any slot). I then tried CLR_CMOS (when my computer was turned off and unplugged) and it still did not work, and I also tried switching the EZ XMP switch from EZ to XMP, and it still did not work (I then switched it back to EZ).
I then tried to reinstall my old RAM into the same slots it used to be in, C2 and C1, and I had the exact same issue. I tried solving it the same way, testing with one stick in every slot and pressing MemOK! and it did not work in any slot.
I then tried booting with no RAM installed at all, and I still get error code 53, even though I should be getting error code 55 as this is “Memory not installed”
However I then tested the other stick, and it seemed like I was having the same issue, until I put the other stick into slot D1 and then it instantly booted (before even pressing MemOK!), even though it would not work in the same slot it used to be in. I then tried inserting the other RAM stick into another slot, but every slot I try to insert it in the RAM is not detected.
Is there something I need to do to get my new RAM to be detected? (or even just to get the second stick of my old RAM detected).
I’m particularly confused as to why my old RAM will now only work in a slot it previously wasn’t even in, and only one stick will work in any slot.
