If you have a sabretooth fx990 it'll work on it even if it's not on the official compatibility list. Rather than buy 16gb 1866 which wouldn't be v.good for overclocking this was on sale so how could I not grab it? fabulous.



After some trial and error I got this to work perfectly at full speed (ddr3 2400) with my fx4350 which overclocks the on-cpu memory controller of the fx chip by a whopping 29% but as I watercool my cpu & monitor the temps I feel comfortable with that + I run the cpu at 4.9ghz and it has been ultra stable in every circumstance eg. playing tomb raider on ultra at 100% cpu & passed a p95 stress out for a couple of hours on blend however at the very peak of this year's (2016) heatwave I had to dial down my overclock down one notch to 4.8ghz because when the water temp was ~41c and ambient was ~35c although the delta t was only about ~5c that was the warmest it had ever been and probly just enough to tip it over the edge.



In the cooler months from Jan-Jun it was running at 37c water temp with a delta t of about 12c as ambient temps stayed around ~25c and it was rock steady. I know that I could be using a bigger radiator and better high pressure fans to sustain the heavier overclock



anyway it helps me kick the upgrades down the road that little bit more. Though aged and reaching the end of ddr3 I haven't found anything in my normal pc usage that has required a larger upgrade yet there is some milage in the old banger still.
