I'm using a Dell Optiplex 380 which is a G41 also. They only sold it as 2 core 4GB RAM and didn't bother to install the 95W limit that other Optiplexes of that era had. I have a 120W X5470 running in it. So it's not the chipset itself. But the fact that it only supports 2 RAM slots means it did lend itself to that market. As far as confirming goes userbenchmark is pretty good if there's a large enough sample. In fact that's where I found out the Opti 380 would suuport an X5460. I just took that a step further. I didn't look at all 970 examples to be sure but it was looking pretty consistent, and the fastest systems come first although that's usually an over the top GPU as much as anything else.
Geekbench 4 is another place to look for CPU s and overclocks.He can look into it further if he wants to , but it looks that way to me.
My problem is the pimodded E7500 in my system at Geekbench is running the RAM @ 1333, and mine only goes 1066.
Now i have to obsess over that! IDK if the pinmod does that too or if there's a newer BIOS?
The other issue you may have is Intel systems from that era needed low density RAM and that's getting hard to find now. I had some G Skill that worked, but when one failed the new kit (same part#) didn't work.
Crucial CT2K51264BD160B is an 8GB (2x4GB) low density kit that can run from DDR3-800 to DDR3-1600 speeds. 1.35V. also but can run as 1.5V. Working fine in my G41 Optiplex. But G41 came in DDR2 also. The same issue exists there.
