I asked this in a previous thread, but I think people were confused thinking I was asking for brands of Ram, when I meant more what type... so figure a new thread may be more clear. I have the base i5 mac mini model, currently with 2 GB of Ram. I have read that there are reports of people getting a decent (relatively speaking, 5-15%) boost in frame rates if their machine has a HD 3000 chipset when adding speedy ram. What I am unsure of, however, is if the i5 supports 1600 MHz (or perhaps even 1866MHz) speed Ram. There are threads in this forum about people using it with primarily i7 models and having success. And I have seen other reports for standard PCs too. But again, most seem to be using i7s... have read some people with i5s get at least 1600 Mhz working, but am not 100% sure how accurate that is. I was considering trying either Kingston's HyperX at 1600, which is about $70 right now, or Corsair's Vengeance, at $44 or so. I have read reports of HyperX working, but none for Vengeance yet. There are other brands of fast ram too, but most of their timings are off, so don't want to risk those. Any help appreciated here.
