Extra memory installed not detected in BIOS or Windows


Recommended Posts

Hello friends,

 

I have an HP desktop from work that I wanted to install some extra memory in and it is not detected. I have attached a picture from the BIOS. The PC originally had 2 DIMMS of 4GB totaling 8GB. I added 2 additional DIMMS of 4GB to bump the total to 16GB. After adding the additional memory, the BIOS doesn't see it as illustrated below and of course Windows does not either. There was a newer BIOS update, so I did that update with no luck. I did some googling and there were a few things to check within Windows, but I gather since it isn't detected by the BIOS, those won't matter.

 

The only other thing I can think of is trying the additional sticks one at a time to verify they are good, but beyond that can't think of what else to try. Any thoughts? Thank you!

I assume you have checked that the dimms are compatible and properly seated? Otherwise I can not think of any good reason for them not to be detected.

Forgot to mention about seating them. Yep, I made sure they snapped in to the slot. As far as compatibility, I'd assume so. I'm going to mess with it tomorrow and try the additional sticks I got individually. It's so weird to add the sticks and not be detected, unless they are bad. I'll try running mem test as well

Yup, that's the best thing to do right now!

Yeah, memory stick could be bad. Reason why it's not picking it up. MemTest it up.

 

Might want to try ONLY that default stick alone, see what you get.

I removed the original pair and tossed in 2 pairs of 4GB. Of those 2 pairs, only one worked. When I put in the original pair with one of the new pair, only 8GB was detected. I suppose worst case is the DIMM slots themselves are bad, but I think you both are right with Memtest, I should get a straight answer, I hope.

The new memory is compatible right?  For example, you didn't purchase DDR3L modules?

HP are a pain for ram you have to get the right modules or they just do not work, you aresure that machine can use more ram than was installed and the modules are compatable?.

His computer says 32Gb is the max. So is well in that range.

Just wanted to give you all an update. Out of the 3 pairs of RAM I was given, 2 of the pairs were bad. I plugged them all individually and the computer started beeping at me with a red light on the front with those 4 sticks. I put the original pair of memory and the one good pair together and I was able to get 16GB. Thanks for all your input!

      At least some of its DRAM products are indeed defective, admits SK hynix
      by Sayan Sen

      SK hynix, one of the largest DRAM chip makers in the world, has confirmed that some of the DRAM products it made were indeed defective. In a statement to The Register, the firm has said:

      However, it was quick to add that the number of defective products that were circulating around in rumors was hugely overblown. "The scale of the potential losses mentioned in the rumor is absolutely not true and exaggerated", it added.

      According to such rumors, the company was having to deal with around 240,000 defective memory wafers, which is an enormous number and a huge cause for worry especially in a time of serious massive global chip shortage.

      Consequently, the shares of the chip giant fell 0.78 percent to 127,500 won. Clearly upset about this entire situation, the company has requested a police investigation for looking into whosoever may be spreading such rumors.

      Hello, I got some new RAM for my brother (doubled the size, and got 8GB) but am I missing something?
      Minecraft plays at 0 - 10FPS!
      How can I force play Minecraft to play at least at 30FPS? 
       
      (p.s.) Not with a problem with my main computer. My own computer which has 12GB RAM can play at 60 - 100FPS.

      Samsung discovers new material for semiconductors
      by Paul Hill



      Samsung has announced the joint discovery of a new material called amorphous boron nitride (a-BN). Its researchers at the Samsung Advanced Institute of Technology (SAIT) worked with the Ulsan National Institute of Science and Technology (UNIST) and the University of Cambridge to make the discovery. The collaborators published their findings in the Nature journal and believe that the material will “accelerate the advent of the next generation of semiconductors.”

      Explaining the newly discovered amorphous boron nitride, Samsung said it consists of boron and nitrogen atoms with an amorphous molecule structure. The Korean firm said that the new material is derived from white graphene but that the different molecular structure makes a-BN “uniquely distinctive” from white graphene.

      Samsung said that a-BN is expected to be widely used in DRAM and NAND solutions because it’s able to minimise electrical interference and can be grown on a wafer-scale at a relatively low temperature of 400°C.

      Commenting on the material, Hyeon-Jin Shin, a graphene project leader and Principal Researcher at SAIT, said:

      The firm didn’t give a date on when it hopes to start using the new material in its hardware products but did say that it would be applied to semiconductors, especially DRAM and NAND solution, in next-gen memory solutions for large-scale servers.

      Hi,

      I have Aorus Master X570 with Ryzen 9 3950X and separate graphics card (ASROCK Radeon RX 5500 XT Challenger D 8G in PCIe 4 16x slot)
      I have installed 4x 32GB DDR4 corsair modules (VENGEANCE RGB PRO 64GB (2 x 32GB) DDR4 DRAM 3000MHz C15 Memory Kit) to it which makes 128 GB in total.
      I have the latest BIOS (F11).

      However I'm not able to use all 128 GB. My system only has ~126GB available, more than 2GB are reserved.

      Is there some setting in BIOS i need to change to have the full capacity or RAM available? Is this somehow pre-allocated for some internal graphics (some ryzen do have internal GPU).

      I'm using Linux (Kubuntu 20.04), here are the outputs from some relevant commands:

      Samsung has shipped one million EUV-based DRAM modules
      by Paul Hill



      Samsung has announced that it has shipped one million 10nm-class (D1x) DDR4 (Double Data Rate 4) DRAM modules. The new product is based on extreme ultraviolet (EUV) technology. The modules have also completed customer evaluations opening “the door to more cutting-edge EUV process nodes for use in premium PC, mobile, enterprise server and datacenter applications.”

      According to the Korean firm, it is the first to use the EUV process to develop DRAM products. It helps overcome challenges in DRAM scaling by reducing repetitive steps in multi-patterning. This leads to enhanced performance from the hardware as well as a shortened development time.

      Discussing the product, Jung-bae Lee, executive vice president of DRAM Product & Technology at Samsung Electronics, said:

      Samsung plans to fully deploy EUV in future generations of DRAM products starting with the 4th-generation 10-nm class (D1a) or the 14nm-class DRAM. Samsung expects to produce those products next year.
