Is it ok to upgrade RAM in the computer

it does not affect anything right?

It's OK with me. You can change your keyboard, monitor, mouse too.

And change your underwear once per day, will make your mom happy.

Why do you want to expand RAM if it doesn't affect anything

It definitely affects computer efficiency making swap file utilization less frequent.

What operating system do you have? (Operating systems have limits of memory they can operate on.) And, can it use the larger quantity of memory you wish to have?

How much memory is present?

Can the chipset on the mother board address more memory than is installed?

If you can increase memory and have the chipset address it and the operating system use it, then you should do no damage.

Finally can the software you want on that computer make use of the memory?

Are you asking if adding RAM will affect your chromatography software/operation of your chromatography system?
-might speed it up

Are you asking if adding RAM will cause an FDA auditor to get his panties all bunched up?
-only in the mind of my supervisor

I am not in the GLP lab. It is just want to increase software speed.

If your computer is able to address the memory, you may see some kind of increase. But it depends on what the choke point is in the system. If the computer has insufficnet memory and has to swap memory segments to and from the hard drive - yes. If your computer already has adequate memory but spends a lot of time reading and writing data to the disk because it is designed to do that no matter how much memeory is present, then increases in speed, if any, will be less dramatic.

Use a performance utility to see how much memory is being used. Windows provides Task Manager to do this. Other operating systems have other tools. If you are using more than about 80% of physical memory, then an increase in memory makes sense. Check to see if the computer can actually handle the memory (Mother board and operating system issues already mentioned.) If the computer can handle the memory and you are not sure - memory is relatively cheap. Just do it and get back to doing chemistry. That 80% number I gave (which may not be the best number for current operating sytems - but will do) comes from running an HP-3000, when we purchased expensive profiling software and took a 1-day class to understand the diagnostics before committing to spending to add another 16 or 32 K memory in the machine. (It might have been smaller additions - but memory was expensive, once up on a time.)

Off topic and just curious: HP3000 not HP1000? What did you run on HP3000?

[MSCHemist]

Should be no issue. The computer will continue to boot up unless the memory is bad and it might refuse to boot. I just upgraded the old Kyak running my 5890-fid. I put windows Win 2000SP4, A big 200gb IDE hard drive, and an extra SODIM of SD RAM to bring it up to 384mb, and a PCI, USB 2.0 card. It works better now.

Csaba: We built a LIMS with the main database on a 3000 and lab instrument comminication with a 1000. It was a good system - back in the day.

Hello.
What kind of software you want to speed up ?
We change 8 to 24gb ram on computer where MassHunter works and dosent help much...<5%
improvement in batch analyze speed. Probably ssd disk would be better in this case (MassHunter still need a lot of love/optimization from Agilent programers...).

It's worth checkingon a site like Crucial (a memory manufacturer) that you buy compatible memory. There are various parameters whicih I can't remember, but if you start mixing them up then you can have an unstable system that crashes from time to time. Otherwise there is no detriment to adding more memory.
