  1. I am struggling with my Vista home built. Specs are as follows:

    MSI P-CD53
    8 gigs of Corsair Ram
    i5 Intel Processor
    Vista 64b Home Ed
    BFG GTS 250

    No special programs or other hardware. No overclock etc.

    I am getting constant errors and they all seem to be different. Please help.

    One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause and, of these, memory hardware failures are the most common.

    0xA errors are caused by either hardware or drivers attempting an IRQ level they shouldn't.

    We need much more information from you like a) hardware specs including type of RAM installed, psu make and model plus wattage, etc., b) the software security your are running and c) are these crashes random or when you are doing something specifically.

    I can only guess at this point but the symptoms remind one of corrupted memory but, again, it is only a guess.

    Mobo-MSI P55-CD53
    RAM- Corsair XMS3 DDR3 8gb
    PSU- Antec Earthwatts 650watt
    GPU- BFG GTS 250 Nvidia

    As far as software security, are you referring to an anti virus? I am using AVG Free at the moment. The crashes are completely random and even happen when the computer is just in screen saver mode( I disabled the sleep function)

    Three things that can help in the diagnostics:

    1. Try running your system with less than 8 Gigs (I'm assuming the memory is recommended by MSI for this motherboard).

    2. Check to see if in the BIOS the recommended voltage for your RAM is set as the specs state.

    3. Run Memtest on your memory.

    See the link below and follow the instructions. There is a newer version than is listed but either one should work. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

    Let it run for a LONG time. The rule is a minimum of 7 Passes; the more Passes after 7 so much the better. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

    If you have errors you have corrupted memory and it needs to be replaced.

    Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

    Full Memtest ran. I tested each stick singly with 8 passes and all four together with 8 passes as well. I am at a wall. Anyone with any other ideas?

    Did you try to do #'s 1 and 2 in my previous reply?

    Yeah I was just messing with the BIOS and it was set to 1.5v. Spec is 1.65v, I changed it and am hoping that was the problem. Is that enough of a difference to effect the stability?

    Thanks for your advice and savvy Route44

    Believe it or not, yes, it will affect stability. We have seen a lot of corrupted memory issues in 2009 that weren't really bad RAM per se but that the BIOS had set the memory at the wrong voltage. Many times when the voltage was corrected the stability issues disappeared.

    A few motherboards are only designed for certain memory voltages too.

    Another thing we have seen is some boards just don't like 8 gigs of RAM even though they may be designed for them. Why is the question without a really good answer.

    By the way, nice build. :grinthumb You certainly know your hardware. I'm jealous! ;)

    The voltage is set to as close to 1.65 volts as I can get it for the ram. Is there any other tweaks to the ram from Bios that would make the PC run more effectively?

    First, are you getting any more BSODs since upping the voltage?

    Are you experiencing your new build as less than efficient and if so in what ways?

    bigsugardaddy1 TS Rookie Topic Starter

    No more BSOD's. I even turned on Xmp and am running at 1600mhz. I also ran a burn test and need to get rid of my dumpy stock cooler. Is there any other tweaks you think would help me maximize my ram etc.

    Excellent! Thanks for getting back to us with the information because it confirms that too often the BIOS will set the voltage at the wrong setting resulting in what you have experienced,

    You have a powerful system. I don't know if you overclock but if you don't it means to push the specs of your RAM, cpu, and motherboard beyond the manufacturer's specs. Keep in mind that once you do your warrenty is voided.

    Many people overclock and if you want to see people looking for suggestions and results I recommend going to the Overclockers Forums. Great forum and very helpful. It is a good community and is helpful like TechSpot.

    I belong there but have yet to oc! :blush: The forum is very diverse and I have gotten some excellent advice on other matters.

    With 8 gigs of RAM you are already doing well.

    The computer has rebooted from a bugcheck. The bugcheck was: 0x00000050 (0xfffff6fc5047fbd8, 0x0000000000000000, 0xfffff80002ed6918, 0x0000000000000002). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 102709-26379-01.

    Please Help!

    Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

    Attach your most recent minidumps since you installed 7. Please don't Zip them individually.

    First dump is another 0x50 error and it cited cdd.dll as the issue. This is a file used by Canonical Display Drivers created by Microsoft.

    The other is 0x3B and it said memory corruption. :(

    Would running my ram on 1t cause a problem? The other thing I noticed is my CPU is running at 1300mhz all the time...I am not sure why...

    Try running 2T and see if that helps. What is your cpu designed speed?
