Hello [NAME],   I'm Joey from Dell community enterprise social support team. I ran a check on available parts for replacement for M910, but the SD module is not listed as a replacement part within Dell component searches. Therefore, RWGG5 is an unofficial part that can be replace.    Though, I gave a deeper search to check RWGG5's description. In M910 mainboard, RWGG5 is listed as one of the mainboard build. Hope this helps.
I have eight M910 blade servers, and am quickly learning that the dual SD card readers, in these machines, don't last long. I need to replace these modules in two of my servers, and have replaced it in one, already.  When I look online, trying to find places to buy them, I see part number "RWGG5" being stated.  One description says that it's for the M910.  Another says that it's for the M620.  Another says that it's for the M620, but the picture looks different.  It shows the card with a USB port, which mine doesn't have. With all of this confusion, I just want to know what's compatible with what.  Will all of these work in an M910 because they all have this RWGG5 part number? I'd hate to start buying parts that I can't use.  So if anyone knows whether or not these are all compatible, I'd love to hear from you. Here are a few of the links that I'm referring to: [URL] [URL]#ProductDetails [URL] Thanks for your time, and for any help that you may be willing to provide.
Is the RWGG5 Compatible with the M910, M620, or Both?
