I just purchased the 840 EVO SSD and the motherboard I am currently using is a Gigabyte 990fxa-ud3 rev 1.1 and it seems that the IOPS random read are really low. I optimized and tweaked everything and all my sata ports are 3.0. AHCI is turned on via windows and bios and all my options in magician shows everything is GREAT and passes! I even switched all the sata ports. The numbers are all high but when it comes to IOPS random reading the numbers are 36000 - 40000. It doesn't go more than that. I am stumped on this one. Again I optimized windows settings and within magician. Trim is on too. Please help I have been at this for 4 days now. Thanks dearly.
