    Unhappy Crosshair V- intermittent solid HDD activity light and unresponsiveness

    Hey guys, I've got the below specs.

    Crosshair V Motherboard (BIOS 1402)
    16GB Corsair Vengence DD3-1600
    AMD FX-8150 w/ oem water cooler
    2x Radeon HD 6970
    1TB Western Digital SATA III HD
    800 Watt Corsair PSU
    Windows 7 Ultimate x64

    OC: 4.2GHz
    Bus- 224
    Multiplier- 19
    CPU Voltage -1.31250V
    Ram is running at like 1440mhz or something like that

    I have only noticed the problem when I'm overclocking, though I've tried several different settings. I actually scaled down to 4.2GHz to try to get rid of the problem. Basically I'll be using my computer and the HDD activity light goes solid. I can move the mouse around but when I click or open anything nothing happens. If I'm watching a video it freezes. This happens for about 2 minutes maybe once every 20-30 minutes. Once it has passed the HDD activity light turns off and everything I clicked on or shortcuts I pressed during the lock up are immediately spammed/executed. If it happens while I'm playing Battlefield 3, the game continues but next time I spawn my guns are invisible and I can't shoot and missing sound effects that come from my movement; when the lockup is over I get the dying sound effect and my guns reappear and everything is back to normal. I'm new to overclocking so I'm wondering if maybe one of my OC values are not proportional or something. I run Ycruncher to make sure the overclock is stable and it didn't throw any errors or heat up too much. I'm going to try when I get off work to run at stock settings just to make sure the problem doesn't happen at when not overclocking. I also have a slight hunch it might be my HD, just don't have another to test yet. Thank you guys for your help

    Things I've tried so far:
    Re-installed OS
    Updated AHCI drivers

    Welcome to the forum !
    You might try and raise your cpu voltage a bit, maybe to 1.35v or 1.36 and see if that helps.
    You list your water cooling as "OEM", is that the AMD system or what ?

    Thanks for the welcome! You are correct about the cooler, it is the one available from AMD with the FX-8150. With the voltages I'm running now I think I'm pushing the temperature limits already. I think I've either got a less than awesome chip or my cooler is not working well. I use ycruncher for my stress test and AI Suite II says my CPU temp gets up to 61C on a good day and 63C on bad day. From what I hear the absolute limit is 70C but a lot of people seem to try to ride at 61C. Am I approaching this the right way; is it okay for the temp to be higher during a stress test since it's a very unnatural process? I think my idle temp is pretty high as well.... AI Suite II shows my CPU temp to be 34C-37C at idle. Unless maybe AI Suite II isn't showing core temp but socket temp.

    I'm not sure why because I didn't change anything, but it didn't give me any trouble yesterday. I tried some different OC settings that didn't work and ultimately reverted back to my previous OC profile. After that I didn't have any issues even though I was running the exact same settings. I'll run her hard again tonight just to be sure since the problem is intermittent. Thanks for your insight by the way!

    What are you using to read your temps and the temps you're listing are they cpu temps or are they core temps ?
    The core tamps are the ones you want to be paying attention too, the cpu temps are usually being read from a sensor in the socket under the cpu and the core temps are being read from within the cpu itself.
