Hey guys, I seem to be getting very slow speeds on my freshly installed 240gb drive.
I got the same result from CrystalDiskMark and ATTO benchmark.
Windows was a fresh install onto the drive, AHCI and ACPI 2.0 are enabled in the bios, windows reports TRIM commands are enabled.
They seem to be consistent with SATA 1 speeds, though my board (Asus M4N98TD EVO) is SATA 2 capable. Apparently nforce chipsets do not play nice with sandforce ssd controllers. I upgraded my nforce drivers to the latest version, did not make any difference.
There are numerous reports of this problem on various other forums. OCZ seems to have solved the problem with a firmware update. I was going to update the Sandisk firmware, but noticed there was no mention of this problem in the update notes, and the ‘update at your own risk’ scared me off. Am I going to void my warranty by updating? Is there anything else I can do?
