The Constantly Crashing P7P55D

Now let’s consider a different problem, also with an Asus motherboard at its core.

I’d built a system running a Core i7 860 and the Asus P7P55D. The GPU installed was an AMD Radeon HD 4890. The system booted normally, and Windows 7 installed with no hiccups.

Periodically, the system would go into sleep mode – this was normal – but would then lock up. This was decidedly not normal. Occasionally, the system would lock up during multiplayer gaming sessions, too. Updating the BIOS didn’t fix the problem.

Then I came across several posts on several forums suggesting an incompatibility that was specific to the Radeon HD 4890. So I swapped in an eVGA 260 GTX Core 216 SSC.

Lockups still occurred, with the same frequency and symptoms. So the problem had nothing to do with graphics cards. Finally, I removed the memory – some early Corsair DDR3-1600 (though it was only running at 1333MHz) and swapped in some OCZ DDR3-1600 (also running at 1333MHz.)

The system has now been running smooth as silk over multiple gaming sessions.

These particular Corsair memory modules had actually given me fits in a number of different Intel-based motherboards, including P45, X48 and now a P55 motherboard. The Corsair memory is a 4GB kit, labeled CMS3X2048-1600C7DHX. What’s interesting about these modules is that when you drop them in an AMD AM3 based motherboard, the system seems to run perfectly fine. It’s quite a mystery, but illustrates how complex the issue of compatibility between components can be.

Lesson learned: nothing in particular, except to maybe to not trust forum posts, even multiple posts that may agree with each other. The graphics card wasn’t the problem here – once again, it was DRAM.

One other thought: despite rapidly falling DDR3 memory prices (or maybe because of rapidly falling prices), the state of the art in DDR3 modules seems to be evolving rapidly. This seems to create incompatibilities between specific motherboards and specific modules. I’ve had Kingston modules run great in Gigabyte motherboards and behave in a crashtastic manner in Asus boards. I’ve had OCZ memory behave badly in Intel boards, while running like a champ in eVGA X58 boards. Whether I adjusted timings, or ran in default modes, didn’t seem to matter.

How anyone can keep track of which modules run well on which motherboards at this point in time is a mystery. So the lesson here, I suppose is: if you don’t have a large supply of different modules and motherboards on hand – and most people don’t – make sure you buy your components from a reseller with a robust return and exchange policy.

    No, the problem was crap his daugther installed.

    Linux is not the answer. I run a q6600 at home with a slower video card, with vista since vista RC1. Its never been what I would consider slow.


    You linux FanBozzzz, need to get off the stupity that the solution to every problem is linux.

    PC doesn't boot. Get linux
    PC Slow . Get linux
    Viruis. Linux
    UGly. Linux
    etc, etc, Linux

    I know Windows better than Linux. At work I use Windows and I have experience with all versions of Windows. The reason I got into Linux was because I wanted to know enough about Linux to check out the myths.

    My experience with Linux is similar to what petersterncan described in the post below. To you I would say, give Linux an honest try. By honest, I mean willing to learn and make an effort to overcome a technical problem. After that, you will may be revise your opinion.

    I seem to be a Linux Fanboy, actually I consider myself as a beginner. Lots of things I still need to go to forum to get help. However I know enough to recognize that Linux has some strengths that Windows doesn't. After weighting pros & cons, Linux is a better choice for my home usage. Also to backup Peter statement, have a serious look about Virtual Machines. Virtualbox in particular. This solves a lots of problems whenever I need a native Windows environment, actually I use it a lots.

    Ugly Linux? This is also a myth. I have played with enough desktop effects, they are fun at the beginning but becomes either annoying or useless in the long run. Just trust me on that, it is possible to make Linux desktop look very nice. But not everybody is interested by eye0candy effects.

    I was joking.

    Not that linux was ugly.

    but that if the PC looked ugly, installing Linux will fix it.

    Look at the target audience. A 16year old highschool female. And the anandtech nerds think LINUX is the answer? WTF. Why?

    I know the reason why, its because the linux fanboism is strong here. The same line of reasoning as to why you shouldn't throw hardware at the problem, should be used at software.

    Theres no need to throw out XP, or Vista, Or Win7 because the underlining windows install is bunk at this point.

    The first step to the problem with this box is to format the drive an reinstall the OS. Odds are the freshly installed OS will run much faster then XP busted, no matter weather or not it was a flavor of Windows, or a Flavor of Linux.

    Personally, I use linux. I dont have the time, nor want to 'learn' another OS. For me windows works.

    I'm am so overwhelmed by everything in Winworld alone, There must me some 30 new apps everyday and after 15 years you get to know and use some 300+ software, I would really like understanding more of linux, but I don't see the day I'll be done understanding the inner parts of Windows. I fear It would be a 6 month adaptation, that would not benefit that much for me.

    I must agree that most slowdowns are because of software problems, I think he should have cleaned the reg or monitored process then added 2gig at last.

    I recently made the switch to Ubuntu Linux 9.10 64-bit.

    I'm not a fanboy for Linux... but I do know some of the practical advantages... such as not being a huge target for viruses and malware the way Windows is.

    But anyway... after my switch... for software problems, I can say with confidence that Linux Can be the answer for 100% of all the Windows software problems.

    What ever doesn't run under Linux natively, you can run within a Virtual Machine under Linux using a package such as VirtualBox. Could can also use other apps such as Wine.

    Note that prior to my switch, I was running Windows 2000 Professional... I wanted to switch to 64 bit for longevity and performance and I wanted to get off an OS that was about to have support discontinued.

    But my concern was being able to run anything... even Windows Apps. When I learned about the VirtualBox application... I know I can practically run anything... or at least any OS that runs on x86.

    For it to work well, all you need is sufficient memory, disk space and processor... in my case... a newly purchased Athlon II x4 630 with 4GB ram and a 2TB HD...

    Windows 2000 works faster now on the new hardware within a virtual machine than on my old hardware (single core Athlon, 320GB hd, 512mb ram)

    And the nice thing about having Windows within a virtual machine... you make one base image and work off a copy. Screw up that copy? No prob... delete it and copy the base set up again. Concern about data loss? No worries there either... you just copy the data to the part of the disk that is not part of the virtual machine.

    Plus Linux boots up and shuts down faster than any Windows PC I've ever used...

    The hardest part of my setup? Getting my netgear Wireless N PCI adaptor working... which was resolved by downloading some closed-source Broadcom drivers.

    Note as well that I did a clean install to a new hard disk to minimize any chances of headaches.

    I find "upgrading" an OS only saves you time in the short run... in the long run, you end up having to do a clean install anyway.

    So yes... I've concluded all Windows software problems CAN be fixed by switching to Linux. All it takes is a bit of research and self-education.

    Now if the hardware isn't up to snuff... that's another story...
  • nubie - Wednesday, January 13, 2010 - link

    I'm afraid custom drivers for obscure hardware (6 axis 3D controllers anyone?) won't run in that sort of environment, neither drivers for video cards (with stereoscopic or TV-Out support for instance.)

    It is an interesting solution, but until the virtual machines support installation of drivers for the OS in the machine it won't work.

    May not be a concern for software people, but if I didn't need hardware support I probably would have moved to Linux a few years ago.

    NO no You don't have to install linux, just run a live-cd on it and
    give it a try.
    So then will see what's going on if the hardware is the problem or the xp ?

    Been reading this site for years but this is the only article that has made me want to reply back, wierd. Anyhow, it's a great read, and reminds me about the real troubles of DIY PC people. Some stuff you encounter is just plain silly, and you usually broke your own rules doing it, but hey it happens to the best of us.....
    I have had sound cards that slowly turn down their volume all on their own, motherboards ressurect themselves after sitting in a box for a couple of years [ram in last slot only, fixed it] and CPU's that decide not to OC even by 1MHz, when you had them happily runnning 1GHz overclocks for years. I know I fiddle too much and cause most of these problems myself, but hey sometimes that's half the fun isn't it?
    As for your 5870 problem, don't worry mine also does some real wonders on me, but so far I've found the newer drivers/bios are slowly fixing these issues so I beleive most of them are fixable errors and not it being a shoddy card. That's one thing us Aussies don't have the luxury of, RMA's. You do that over here and good luck if you see a replacement in 6 months time.....
  • nubie - Wednesday, January 13, 2010 - link

    I think I can beat your story, how about a Cyrix MediaGX system that won't run over 233mhz when it is a 266mhz chip, and if you put the memory in the slot backward (and then return to the correct way) it will overclock well past 300mhz just fine.

    That one was very very strange. And I mean strange!

    Now you're bringing back some memories. Here's two that make me feel REALLY old:

    Story 1: I picked up a 486-DX4 100 MHz CPU (yeah baby!), motherboard to host it, and some new RAM to replace my aging 386 so I could kick some butt at DOOM2 over IPX. This was my first build that was entirely self-funded, all from a computer show at the local community college. In my eagerness to get it together quickly, I managed to put the CPU in without aligning the "pin 1" arrow on the motherboard with the "pin 1" arrow on the CPU. I assumed that if the CPU dropped in so easily, it MUST have been in correctly. When I plugged it in and nothing happened at first, I was a bit perplexed. Then I heard the POP! and saw smoke coming from my brand new CPU. Needless to say both the CPU and the mobo were toast.

    Story 2: This one is a bit shorter, and much older. Anyone here remember the 5.25" Seagate 20 MB and 40 MB HDD's with the gold colored casing? If you do, then you remember that they were very expensive in their day, and you'll also remember that there was a resistor pack that had to be installed or not depending on whether the drive was master or slave on the controller. Well, I got it wrong one time, the drive did not survive. Dad was not happy =(
