is there somewhere a list of all the supported CPUs for System x server? I own the configuration system x3755 8877-4RG. Original 8218 Opterons (dual-core) are installed. Can these CPUs be replaced by e.g. some quad core opterons 83xx? many thanks in advance

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Requests for product, service, or learning material recommendations are off-topic because they attract low quality, opinionated and spam answers, and the answers become obsolete quickly. Instead, describe the business problem you are working on, the research you have done, and the steps taken so far to solve it." – mdpc, HBruijn, Journeyman Geek, Sven, TheCleaner
Most people would look up the vendor documentation and find something like the supported hardware:
AMD dual-core 8000 Series Opteron processors
not quad core and
Dual Core Opteron** Processor Model 8212 40K1200 Dual Core Opteron** Processor Model 8214 40K1201 Dual Core Opteron** Processor Model 8218 40K1202 Dual Core Opteron** Processor Model 8220 SE 40K1203
But with a system that hasn't been sold as new for the past 7 years you probably don't care about vendor support anymore.
Then a quick look at the CPU specs show that despite using the same CPU socket the 8200 series run at a higher CPU voltage than the 8300 series and my assumption is that it is unlikely that the server motherboard will automatically adjust for that...
When your system is already 7 years old, why invest in it? With new hardware you can get 32 cores in a dual CPU system, supporting more memory and lower power consumption.
