I have a PC based on an Intel e6750 Core2Duo, and 2 sticks of 1 GB each of DDR2-800 running at 5-5-5 timings. Running Win7 32 bit.
A friend gave me a 2 GB stick of DDR2-667 that he didn't need. I plugged that in, works like a charm, however, all my memory works at 667 levels now (which makes sense, I think).
Correct me if I'm wrong, but for 1333 FSB that the e6750 has, isn't the 667 ram speed the optimum speed anyway? Wasn't DDR2-800 overkill to begin with?
I do not intend to overclock, by the way.
There shouldn't be any performance loss, right? I mean, 2 * 1 GB of DDR2-800 at dual channel always get trumped by 2 * 1 GB of DDR2-800 plus 1 * 2 GB of DDR2-667 since the CPU can only use up to 333 FSB (ok, quad-pumped to 1333) speeds...???
Does the fact that I had 2 sticks in dual channel mode and now I have 3 sticks in total play a part at all?
