Samsung 840 Pro 256 GB SSD, Intel 6G/s SATA issue - Asus P8Z77-V Deluxe

Trying to get the best performance out of new Samsung 840 Pro 256 GB SSD. Also increasingly concerned about stability. This drive will host OS, Steam, Origin + games on Asus P8Z77-V Deluxe based system.

Installed Win7 Home Premium 64bit SP1 on it (using 3.0 GB/s Intel SATA for install).
Installed Intel RST Driver: 7 Series/C216 Chipset Family SATA AHCI Controller (iaStor v11.1.0.1006) from ASUS download

Connected 840 Pro to the Intel 6.0 GB/s SATA, issues:
  • When running Samsung Magician (v4.0) Performance Testing: Gave BSOD (twice) or "Performance Benchmark Failed, failure due to timeout" (twice).
  • Tried to run AS SSD Benchmark: gave BSOD.
  • AnvilPro benchmark: BSOD (read or write)

Drive is otherwise functioning ok (so far), but I can't benchmark on the fast Intel SATA. One other issue: This drive has *lots* of cap/coil squeal, very high pitch whine when under load. Have replaced SATA cable but to no effect.

I have yet to do large copy to it (eg. Steam files) but will try presently. Will RMA obviously if any errors on this.

Magician/AS SSD benchmarking works ok for other controllers on the Deluxe MoBo:
  • On Intel 3.0 GB/s SATA runs ok, but performance is predictably mediocre at ~280 MB/s r/w
  • On Marvell 91xx SATA 6G, better seq. read of 410 MB/s, but terrible seq. write and IOPS.

Thanks for any help/suggestions!

PS. Have 840 Pro 512 MB in my Lenovo x220t, get 500+ MB/s seq r/w, works great..!

  1. Try the latest driver from intel and make sure the ssd has the latest firmware. That at least fixed my problems with the stability.
  2. Hmmmm.... There might be a misunderstanding. You mentioned that you are using 3.0 Gb/s Intel SATA for install which would suggest SATA 2. You also mentioned Intel which would suggest SATA 3. That makes it a bit confusing.

    Your Samsung 840 Pro is a SATA 3 6Gb/s solid state drive. Your Asus PBZ77-V Deluxe motherboard supports SATA 3 6Gb/s ssd's. The ssd should be connected to one of the two gray SATA connectors on the motherboard.

    Did you remember to go into the motherboard's system BIOS on initial boot-up and switch to ACHI mode before installing anything on the ssd?

    The latest Intel chipset drivers should be download from the Intel web site instead of the Asus web site.

    I am a regular here. There have not been any threads about noisy ssd's. Usually the problem is a power supply, fan, or a sound card connection.
  3. are you overclocking? sounds like your bios is messed up . i own 840 pro plus 6 other top end ssd its not the ssd. its your settings
  4. BTW 840 pro wasnt released with bugs. samsung is bigger than that The samsung firmware updates only tweak ur experience not change it .
  5. Thanks all for posts - I'm now sorted. Changed power cable and moved to new socket/rail on Thermaltake PS and drive is now behaving well. Getting 500+ MB/s on seq w/r, pretty good IOPS. Still on iaStor driver.
