I have two sets:
Hynix 4x8GB 2Rx4 PC3-10600R-9-10-E1
Samsung 4x8GB 2Rx4 PC3-10600R-09-10-E1-D2
$50 for each set of 4. Pictures: https://imgur.com/a/76Q4m8X
All have heat spreaders that can be removed. I can’t guarantee they work since I don’t have a motherboard that will run them, but the seller I got them from on eBay was highly rated and these were pulled from working servers.
Edit: Uploaded pics directly to the post for convenience.
