Hi experts,

I'm thinking of purchasing an IBM eServer xSeries X232. The specifications on the IBM website say that the RAM compatibility is " Type: ECC, SDRAM, registered DIMMs ".

Is it possible that I can use some spare Kingston NON-ECC SDRAM that I have kicking around at home in this server? I was not able to locate this answer on either IBM or Kingston's website.


Thanks,

Computer_Dude.

I would not, it may work but will not perform error checking. Most probally it will not work at all due to not being regerstered chips. Go with the right chips they are cheap.

Here is some good info regarding ECC from the people at Corsair

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

NO!

ECC registered is buffered RAM specifically engineered to perform in critical apllications.

It is slower than regular RAM ,but it corrects errors and is very stable in situations where errors can cost mucho buckos.

If you want fast and don't care about errors ,then don't buy a server type of box.

If you anything else,all you'll get is a black screen and funny beeps.

Unless you are going to run a critical app where people rely on uptime,why by a server box.

If it is for personal use,build your own using the fastest out there.

Servers aren't the fastest boxes,just the most stable.

There are gaming boxes that are smoking in terms of performance,but I would think twice about using them in production.

The simple answer is NO.   You can't use unbuffered RAM.

The more complete answer is:  there are two different issues here ==>  whether or not you can use non-ECC modules; and whether or not you must have registered (buffered) RAM.   The answer to the 2nd question is simple:  the server REQUIRES registered RAM ... so you will NOT be able to use the non-ECC modules you have "laying around" UNLESS they happen to be buffered modules (which I doubt is the case).

Whether you can use non-ECC modules is less clear.   In most cases, you could use them and you would simply not have error correction for your memory subsystem.  But the modules MUST be registered.   Note that there are also unbuffered ECC modules available for systems that support them (I always buy motherboards with chipsets that support ECC and always use ECC modules).

Bottom line:   Use the specified memory (Registered, ECC modules).

Thanks guys for in the info. I figured the same thing, but I just wanted to make sure before I dished-out money on it.

I just purchased a higher-end server (IBM XSERIES 360) that's fully loaded.

I'll split the points, as I found a few of your comments very informative.
