I posted the link above to the Crucial system specific 4GB DIMMs in January, and you are correct that they now (Sept 2016) only show 2GB modules. It could be that Crucial can no longer source the 4GB chips with the correct timings and density for your system, same as what happened with Kingston earlier. But I suggest you call Crucial directly to verify.
Btw: did you check if Lenovo has 4GB modules available? Or Ebay? (just make sure that they are for your 6209 model, I note there are several entries for M58p when looking up that system on Crucial, meaning one DIMM does not work for all M58p models.)
Edit: I believe this system requires single density rather than the more common, and now, more available, double denesity.

I really hate to get in on this thread, however it is the only one that seems to be going down the same path that I need.
I have searched all over the place for information about adding 16GB of RAM to my M58P 6209 ThinkCentre. I purchased an 8GB (2x4GB) Ballistix kit.
2 - 4GB DDR3 - 1600
When I add it to the motherboard, with my original RAM (2x4GB sticks), I got a "confirguration attempt" error. After searching for a day on that, I figured that my RAM was not compatible (for reasons unknown to me). When I compare it to the OEM RAM, it looks like it will work.
The Crucial website only shows 2x2GB options for me, but I am not sure why when the motherboard maxes at 16GB.
I have yet to see confirmation that anyone has 16GB of RAM (and what kind) installed, but many have confirmed it as possible. I guess I assumed DDR3-1600 RAM would work as the Crucial website suggests the same type BUT only in 2x4GB sticks.
Am I missing something about the 16GB of RAM? I have BIOS 5CKT77AUS from 5/07/12.

psref.lenovo.com has specs for withdrawn machines.
A M58p 6209-A1U shows 2GB std, 8Gb max. four 240 pin dimm slots.
standard memory in two sockets; two sockets available
1 GB PC3-8500 DDR3 UDIMM
2 GB PC3-8500 DDR3 UDIMM
Lenovo Memory Desktops:
Use your two 4GB memories in slot 1 and slot 3 for dual channel memory. Crucial does not list Ballistix memory item # you listed as an order item for your machine type and model. I ordered memory lately from Crucial. They have the best support site as far as what is available for your machine. Ordering memory is very tricky as far as will it work in my machine.
Note: Lenovo does not market PC3-8500 4 GB memory. What is in your machine today is aftermaket memory, not OEM memory.

Thank you for that information and although the speces are good to look at and read, I am still confused as to wear the 16GB max came into play. I have seen that noted in other places and the website I bought the PC from noted it as well. Crucial also mentions 16GB maximum with 2 banks of 2.
With that in mind, I figured my 8GB (4x2) that came with the machine could be paired with another 8GB (4x2).
Thanks for the input, I am going to keep looking just to be sure before I give up.

Could you provide a link to the website that you purchased the machine from?
The crucial website states:
note the>>not to exceed manufacturer supported memory.
Specs are written when the machine is offered for sale. Later on more details come out as to what memory the machine can support, over and above vendor specs. For example, your machine has two 4GB memories, which is the 8GB stated for the machine.
I do not think you will find anyone usings 16GB of memory on your machine model.
[Edit: see posts below for further comment.].
I have seen some of the comments your have seen on other website.

Sure thing, here is the link: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=9557725
The confusion sets in here:
Memory Module Specifications
Total Memory Size 8GB Memory
Maximum Memory Supported 16GB

Please note that the user in message 17 on Page 2 of this thread says:
I removed the OEM memory, purchased 2 4 gig sticks of Crucial memory, dropped them into slot 1 and 3 fired right up 8 gig. Shut the machine down, added 2 more 1 gig sticks in slots 2 and 4... Walla 10 gig memory running flawless.
So there is no 8GB limit, and 16GB of the correct 2RX8 low-density memory should be possible. [edit: this applies to the 6209 model under discussion, and the Crucial link from the previous page, which applies to that model.]
Note: a M58p owner had difficulty updating directly to the version 77 of the BIOS, and had to update to version 76 first (avail at bottom of the BIOS download page) and then to ver 77.

Looking inside the Psref, there are M58,M58p...some Tower..some Small Form Factor.
Others Ecco models using SOdimm.
Some models show 16GB max memory; others show 8GB max memory. Thus a user would have to look inside the psref for exact machine type and model to determine max memory.
The Lenovo memory compatibility page shows the Max memories that Lenovo supported when said machines were sold by Lenovo.
Your machine is a Refurbished M58p. Tigerdirect states model# RB-LENOVODT00310029. A google search of this model # shows many resellers, including walmart. It has a 1TB HDD, core 2 Duo 3.06GHz and 8GB of memory; not bad.
You state it is a 6209. It sounds like a special build of the machine. I cannot state if it supports 8GB max or 16GB max. A call to Cruical folks might clear up the issue. BiggAl offered this same suggestion 9/28/2016.

I am not getting into memory WW3. The walla 10GB was for a machine that supported 16GB memory.
Psref only shows one 6209 model. A 6209-A1u.
User @ sukosaki has a 6209-???.
Crucial can decide what documentation they wish to provide for a Refurbished 58p, model number above. Kingston can do the same.
The solution, if available, if is outside of this forum, and outside of Lenovo.

the confusion remains.
The crucial picture above for a 6209: vs Lenovo psref specs. Lenovo specs below.
6302 -not listed
I am not keen on crucial bundling the above in 1 screen shot.
I am not fond of tiger direct stating your rebuild supports 16GB max. All the other sites stated you get 8GB. Which is two 4GB, which is over and above Lenovo marketing specs for 2008/2009. Some sites offer your machine with win10.
I am not fond of statements on dms concerning memory options with M58/M58P models.
Your machine is made up of 1 TB hdd, with Intel core Duo 3.06, 8GB memory at a discount place, which is fine. This machine is using leftover parts which did not sell @ premium price in 2008/2009. <My opinion. If you find a M58p with a Intel core Duo 3.06 in any Lenovo spec, report your findings.
I ordered my A57 9702-cto in 2008 with vista and Intel duo CPU E8200@ 2.66 Mhz, with 1 GB memory. I paid $$ for 2GB extra, not no $20. I swapped out the 1GB, via crucial recently for 2GB. I am now 4gb on my south bridge running win10.
If anyone can state 4GB memory in any slot, that would be nice.
