Hi!
I run an ASUS P7P55D-E motherboard. 16GB RAM (4x4), i5 750, HD6970.
I bought a Corsair Force 3 SATA 3 6Gb/s drive a couple of years ago. I was lazy, just plugged it in, and assumed it was fine since it installed Windows 7, booted up and played my games.
Then I decided my system was showing its age, so I started trying to squeeze the components for more power- I overclocked the CPU to 4.01GHz (stable for a month now), learned how to do the GPU via Catalyst CC, and then tested the SSD. It only got around 150MB/s in the peak test (Sequential read on Crystal Disk Mark).
I then spent several days doing the following and testing after each:
- Updated BIOS firmware.
- Checked BIOS, found it was on IDE, switched to AHCI and reinstalled Windows.
- Updated all Windows updates, tested. It went up to 250MB/s, but I now think this is just from being a clean install.
- Installed Corsair SSD toolbox and updated the firmware of the drive.
- Updated drivers for the SATA controllers, chipset, pretty much everything except some of the crapware like Turbo and monitoring tools.
- Replaced the cable with a new SATA 3 6G cable.
- Tried the other gray SATA3 6G port.
- Disabled AHCI for IDE for all other drives, just in case, then restored them to AHCI.
- Checked the registry key commonly suggested as a fix, three times (after changes)- it's on 0.
- Checked in Device Manager, IDE ATA/ATAPI Controllers, the AHCI device, Details, Service- msahci confirms it's on AHCI.
After each of these is usually a couple of reboots and several tests. I've attached one each from Crystal, ATTO, and AS. Around 200 in CDM and AS are normal, and the one time I tested in ATTO, it maxed out around 350, while others say they get up to 500MB/s in ATTO.
If anyone has any suggestions to improve these speeds, I'd love to give them a try! Thanks in advance!
