Hey Gurus Maybe I'm being a little anal here but I'm doing what many of us do and trying to squeeze every last drop of performance out of my rig. Been faffing with RAM timings and some of the smaller numbers have me confused. I'm familiar with the normal 4 and can't seem to get any tighter where I am now (numbers to follow), but I'm wandering if faffing with any of the other timings with improve performance at all. Looking at CPU-Z though there's an odd thing, it might be a typo, I'm not sure, but I thought it work a check. Anyway, currently running Corsair Domi (3 x 2 GB) @ 1600 MHz @ 1.7 V. FSB 200 MHz, CPU 4.2 GHz, (x 21 multi), etc. Timings wise, under the "Memory" tab, this is whats confusing me, in comparison with the "SPD" tab. Highlighted the confusion in bold. My Memory from the "Memory" Tab: DRAM Freq: 800.0 MHz FSBRAM: 2:8 CL: 7.0 clocks tRCD: 8 clocks tRP: 7 clocks tRAS: 20 clocks Row Refresh Cycle Time tRFC: 88 clocks CR: 1T and from the "SPD" Tab, XMP-1600 specs: Frequency: 800 MHz CAS# Latency: 7.0 RAS# to CAS#: 8 RAS# Precharge: 7 tRAS: 20 tRC:41 Command Rate: 2T Voltage: 1.65 I apologise for typing everything but I'm crap with HTML and have no idea how to embed pictures. So my main question is I guess, is tRFC and tRC the same and can I drop the 88 down to 41 in the BIOS for a performance boost? Either that or does anyone have any mad suggestions for improving performance by tweaking? Thanks BLEH!
