Presumably with dram you also have to worry about refreshes, which can come along at arbitrary times relative to the workload.

- pclmulqdq 3y agoYou can control when those happen, too.
- Temporary_31337 3y agonot without affecting performance though? If you delay refreshes, this lowers performance as far as I remember...
- pclmulqdq 3y agoControl of all of this can come at a performance cost, but in the case of DRAM refreshes, it doesn't lower performance if you don't do them, it loses data. Nominally, you could do your refreshes closer together and as long as you know that the rows being refreshed will be idle and you have spare time on the bus, you're ok.
