November 16, 20187 yr Hi, i had 2 8GB ram installed, 16 total. Now i ordered 2x 16GB to upgrade it to 32GB. If i install only one 16GB Server wont start (restart, restart, start no screen and after some time shutoff) If i install 2 16GB Server wont start (restart, restart, start no screen and after some time shutoff) If i install in slot a 8 GB and in slot b 16gb server will start normal and bios shows 8gb in a and 16gb in b. But unraid only shows 8gb, do i need to do anything to get it working inside unraid, or is it just incompatibity? I thought, if it shows in bios, it should work?! (my mb officially only support max 16gb in both slots, but ive read that sometimes more can also work) Do i need to reset anything in unraid to make a ram upgrade working?

November 16, 20187 yr What kind of system/motherboard is this? What kind of RAM? I recall some older Core 2 era HP servers I've dealt with that max out at 24GB even if you install more.

November 16, 20187 yr Have you updated the BIOS to the latest version? I don't know the reason for the BIOS showing it. Possibly it's just reading the SPD chip on the DIMM but that the CPU doesn't actually support that density of RAM (because the memory controller is part of the CPU).
November 16, 20187 yr And the QVL on the motherboard shows a maximum 8GB stick being supported. Always check the QVL for compatibility
November 16, 20187 yr Author I know its not supported. Tryin doesnt cost anything. I just want to know if its normal that bios shows sticks correct, but they dont show in unraid... I always understanted that if bios shows everything, it should work. I updated bios via internal tool from them but it seems to not work (it downloads and restarts and then wants to install the same thing over and over again) Edited November 16, 20187 yr by nuhll
November 16, 20187 yr Author In bios it shows Stick a: 8GB 1600 Stick b: 16GB 1600 with correct manufacturer. Total: 24gb. Edited November 16, 20187 yr by nuhll

Doesn't matter what the BIOS shows as installed, only the 8GB stick is available for use. Period.

November 18, 20187 yr Community Expert 16GB DDR3 are rather uncommon, except ECC registered DIMMs, and likely unsupported, H81 boards only support 2 x 8GB max.
November 18, 20187 yr Author I already know that. Still, other configurations can work. My only question was if its normal that bios shows its working, unraid not.
November 18, 20187 yr Community Expert Just now, nuhll said: My only question was if its normal that bios shows its working, unraid not. It can't work in Unraid or any other OS since it's not supported by the board.

November 18, 20187 yr Author Just now, johnnie.black said: Yes, it's a bios bug Okay, very sad, maybe you can recommend me a board? It seems like i can get max 32gb overall... something like this https://www.mindfactory.de/product_info.php/ASRock-B85M-DASH-OL-R2-0-Intel-B85-So-1150-Dual-Channel-DDR3-mATX-Retai_1190422.html Edited November 18, 20187 yr by nuhll
November 18, 20187 yr Community Expert For that socket you need a board with 4 DIMM sockets, the one linked will work, with 4 x 8GB, not likely to work with that 16GB DIMM, do you have a p/n for it?
November 18, 20187 yr Author What is p/n? XD I already saw that yeah, i can sent my 16gb back, i just wanted to try. Do they only have 1x pcie 16x 2.0 or 3.0... wtf THat seems best i could find: https://geizhals.de/asrock-b85m-dash-ol-r2-0-90-mxgxu0-a0uayz-a1685104.html?hloc=de Edited November 18, 20187 yr by nuhll

November 18, 20187 yr Community Expert Did you try just using that DIMM on its won, does Unraid recognize 16GB?
November 18, 20187 yr Author Like i wrote, it wont start with only 1 stick or 2 new sticks. Only with 1 old and one new stick...
November 18, 20187 yr Community Expert 8 minutes ago, nuhll said: Like i wrote, Yeah, sorry, didn't read the entire thread, though not surprised the 16GB doesn't work.
November 18, 20187 yr Author 18 minutes ago, johnnie.black said: Yeah, sorry, didn't read the entire thread, though not surprised the 16GB doesn't work. Yeah. It was just a test. Some said it can work with other specifications, but i always thought like if it shows in bios, it should work in OS too.
