UDIMM Confusion— my RTX 3060 Zotac Magnus One story

For the last few months, I have been diligently saving money so I can buy a new computer. My HP Gaming Desktop (in the photo above) is now nearing 3 years old. Soon the warranty will expire, and after that, it’s simply a matter of time before one of my best, computer friends i.e. HP Gaming Desktop, dies.

So, I must replace it. For the last three months, everyday, I get up, check Amazon. I check for two things.

  1. Are there any desktop computers with RTX 3060 being sold in India. The answer is no.
  2. Are there any laptop computers with RTX 3060 that are on any kind of discount. The answer is yes, but, they all cost upwards of 1800 $.

I don’t have that kind of money. Prior to the pandemic, 2000$ was a small amount for me. I earned well. Today, phew, with all my debts, its a huge amount of money. More importantly, laptops are almost always 30 to 40 % less powerful. I like them for traveling and checking email, but for main work, I only trust my iMac and my HP Gaming Desktop.

I only trust ‘Desktop’ computers for daily work.

So, this went on for three months. Checking and checking for prices.

Light At End of Tunnel — ZOTAC Magnus ONE


Then, out of the blue, Zotac India, starts selling their Magnus ONE mini PC. Like stock market prices, the price changes every day. I had my eye on the 3060 version.

One day, it’s about 1800 dollars.

Next day, its gone up to 2700 dollars!

Then, for some bizarre reason, it came down to 1200 dollars. Thank god I check my prices everyday.

Okay, that is in line with the expected selling price I had calculated before. Boom! I had been waiting for this moment. I place the order.

But, this Zotac thing, is a mini PC. I comes with a motherboard, processor, power supply and RTX 3060 12 GB. It comes with no hard drive or memory. I buy a hard drive memory and keep it ready. I buy desktop memory, and keep it ready.

SODIMM AND UDIMM — My big mistake


Everyday, I get up and check if Amazon is definitively delivering my computer. I mean, today, RTX 30XX cards are like gold. Look at the wildly swinging prices (as I write this, the same Zotac box is selling for $1400 dollars). At one point, Amazon sent a message saying that my package was delayed.

I got scared.

But, the package was delivered today. Phew!

My mom is excited. My dad is excited. I have been explaining to my parents the ongoing semi conductor shortage. The problem with graphics cards and crypto mining. The ongoing crackdown in China. A lot of this goes over their head but, they are parents to me. They are used to hearing computer words from me since I was 15.

So, dad helps me assemble the Zotac Mini. We open the case. We install the Samsung NVME SSD. Nice. Done.

Then, we move on to the memory. I bought a pair of 16 GB, Red colored fancy looking Crucial memory. We unwrap it, and…

It does not fit!!!

Then, it hit me. Zotac is a desktop Mini PC. It uses Laptop SODIMM memory. I spent hours and hours reading online documentation of Zotac. Made sure of the specs and all that. But, I make one mistake. I buy UDIMM instead of SODIMM.

I forgot that Zotac Mini is a desktop computer that uses laptop memory!

Final Note

Right now, I have my Zotac sitting under my desk, with the memory slots empty. I usually buy everything from Amazon, but, there is a strict 7 day return window for these products. I need to buy SODIMM memory asap, and test the machine.

If I fail to test the Zotac Mini before 7 days, I will lose my return window. We cannot have that.

Father, calls up the local computer shop. The local vendor has promised to get me a 32 GB SODIMM memory stick in 24 hours. So, need to wait.

Meanwhile, the red, cool looking UDIMM memory things? Well, I put them in my main HP Gaming Desktop. I was thinking of putting in new RAM to my old HP anyway. So, all things considered, so far, things are okay.

I work as a full time freelance software developer and coding tutor. Hire me at UpWork or Fiverr. My personal website is here. I also have a Podcast. Thanks for reading.
