X5650 @ 4.0 (200x20) - 4.1 (186x22)
QPI @ 18X all the time (it is uncofigurable on the board)
Uncore @ 16X for 186 BCLK and 14X - 16X for 200 BCLK
EVGA SLI3 (E767) BIOS 83 (the 83 is said to be the latest one, but the sleep bug is still there)
Corsair XMS3 1.5V 9-9-9-9 1333 MHz, set to 200*6 1200 for the 200 BCLK or 186*6 = 116 Mhz for 186 BCLK
MSI Hawk GTX 460 @ stock
Corsair HX620 PSU
Playing BF3 online @ 1280*800, all lows, the graph looks very different than a sample graph that a teammate with a 4770k *stock* sent me. He has a flat line all the time, with constant microspikes (about a few percent tall) every n seconds. Before the spawn screen appears, thre is a spike, but shorter and cleaner than mine. On my system, while the overall FPS is nice, and the graph line relatively even, I see all kind of oscillations around the line, appearing seemingly from nowhere. The spawn screen oscillation looks simply disastrous in my opinion. May I post cropped CPU graph screnshots here or should I create a separate topic in hardware problems (if there is such a subforum)?
The graphs in question are the ones plotted by `render.perfoverlayvisible 1`.
This sort of performance makes we wonder that actually the newer CPU's are better. I need a contant flat line in an online match to have no lag and the cleanest inpit possible, not interrupted but a sudden increase in the frametimes. Can there be a problem in my HW (or HW setup) or is this the limitation for the X58 six-core Xeon?
