What is the impact of unbalanced memory on a Bulldozer Opteron server?

in flag

I have a PowerEdge R815 with quad Opteron 6272 and a faulty DIMM slot at A2. The system still boots with no DIMM installed there, but with warnings of an invalid memory configuration. I can silence the warning, but what kind of performance penalty can I expect?

You obviously lose memory bandwidth. Also, the RAMless(?) socket will experience an increase in memory latency - latency-sensitive applications may suffer a significant hit. Less sensitive applications might run the same way as before.

What the actual impact is in your environment is pretty much impossible to say without testing.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
