RAM Upgrade, Fan replacement, UPS, RNDU4000
I want to upgrade my RAM in my RNDU4000. Comes with 1GB. What is the maximum for RNDU4000? Is it one or two modules? Ive read that the maximum is 4GB for this unit. Is that correct? 1x4GB, 2x2GB? ...

Thank you!
Ive searched at the same A-Tech and there are quite a lot of 2 and 4gb sticks.
Might want to try one 4Gb and also a 2Gb.
As far as i understand the CPU in this NAS support the PC-6400 (800Mhz)
Or is the 667mhz PC-5400 the only one that will work? Can you please provide me link/links to RAM that will work? Both 2 and 4gig.

PC2-6400 will work fine, but will will work no faster than PC2-5300/5400, so you can save a few bucks and get the slower stuff. Unfortunately, A-Tech doesn't label their RAM as to whether it's 2Rx8 or 2Rx4, and I have not bought any in those specific packages, but none I have bought has been 2Rx4 (which won't work). Consequently, I believe any of those will work, but cannot say from personal experience.

So, please provide me links to RAM that WILL work..

I cannot quarantee that RAM that is not fully labeled will work, but I did state that I believe what you pointed to will work.
Beyond that, I am not your shopping assistant.

I will take the risk and try it.
Dont want to spend 130 euro for the G.Skill that will work.
Too expensive.
I have some new alternatives.. costs about the same as the A-tech. around 45 euro
I hope 800Mhz version will work. CPU supports it.

Faster memory will work, but it will work no faster in the NAS.
Crucial also does not fully label their memory as to whether they are 2Rx4 or 2Rx8, so you'll have to go to their site and see if they specify there.
- Anton_Aug 16, 2021TutorI have not found any RAM yet.. very hard to find.
Im looking for 4GB module. 667mhz
