Officially no, Dell has not listed this system for Windows Vista or Windows 7 compatibility and as such no drivers are officially available directly on the drivers and downloads page. It only officially supports 32 bit and 64 bit Windows XP. Download Bacaan Quran 30 Juz.

This means it should be 64 bit compatible. I would run the to be sure it is 64 bit capable. Unofficially it will definitely work with the 32 bit and is highly likely to work with the 64 bit. Many of the system drivers will be native to Windows 7 and/or can be taken from other Optiplex models. I have installed the 32 bit version on a GX520 for example which is very similar.

In your case I would install Windows 7 following my instructions below without activating, this will give you a 30 day evaluation to see how well it runs before wasting any licenses. You should know how well it runs within a couple of hours however. An important note on the hardware, do you have 4 GB of RAM in each system? If not I recommend you upgrade them using crucial memory or install the 32 bit version of Windows 7, upgrading the RAM to 4 GB is more recommended. See for crucial memory, it says maximum of 4 GB but also states 4 slots that can hold 2 GB each. Run the Crucial scan on one of your machines. If you are buying RAM for multiple of these systems, it may be worth sticking 4×2 GB in one to see how much RAM it can address with a 64 bit OS (you can remove 4 GB of the RAM after the test to put in another unit).

See the service manual for instructions in installing RAM, make sure it is installed in matched pairs. I would say its not worth the price putting 8 GB of RAM in each of your machines but it would just be interesting to know as a side note. I did answer a question on this model the other day, someone wanted the 64 bit version of the OS?

Most of the hardware uses Native Windows 7 Drivers with the exception of the Audio Codec. Dell will qualify Windows Vista for Basic Windows Vista functionality on the following OptiPlex legacy platforms: OptiPlex GX620, GX520, GX280, SX280, GX270, SX270, 210L and 170L; Dell will qualify Windows. 63 thoughts on “ Dell OptiPlex GX620 Windows 7 drivers ” Toddy August 17, 2010 at 17:48. I can’t get your fix to work for the Soundmax audio on a Dell Optiplex.

Do you have graphics cards in all the systems and if so what ones or is it integrated graphics? The following drivers are ones that I think should work with this model. Some are for Vista, some are for 7 but of course should work on both OS. Follow my wiki and use the drivers below for best results: Dell System Software (x86) Dell System Software (x64) Dell Device Chipset (x64 and x86) I don't think this one will work Dell Device Chipset (x64 and x86) Use if R304259 doesn't work Video Card - I need to know what one, I will list the integrated/onboard one but get the rest directly from ATI or nVidea.

I would be interested in knowing if they all install for you as I will create a wiki about it for future use. Please also look at the device manager for any errors as the wiki mentions.

Let me know if you have any and what of the above drivers work for you. Also let me know the video card.

From $39.93 Most of the hardware uses Native Windows 7 Drivers with the exception of the Audio Codec. It's been a while since I posted this. Thank you all for all the replies. Three months ago, we managed to install Windows 7 - 64 bit successfully with just even 2 GB memory and was working fine.

But since I had the doubt, I posted this question and even called Dell Tech Support. Dell Tech said, it's not compatible. My research also says because of its processor's architecture, it may work fine. A month of observation, which may or may not be related, we got problems with device drivers and slow performance of the system. That was why we decided to reimage again with Windows 7 but 32 bit this time. So far so good. It's been a while since I posted this.

Anyways, it seems like a decent machine. It's running just a regular Pentium 4 and 2gb of ram.

I upgraded the ram to 4GB and am about to install Windows 7 64 Bit. I just wanted to ask you if you think it will run ok even without the upgraded CPU and SSHD? I don't really want to put my extra 60GB Kingston SSHD in this Desktop to use as a boot drive because I have an HP DV9308NR with two hard drive bays on it's way back from getting a new 2012 NVIDIA GPU installed on the motherboard and I was going to use the Kingston 60GB SSHD if that. I guess I'll just try out the 64 bit and see what happens. Just wondering what you thought since your running WIn 8 64 bit which is way more of a resourse hog.
