  1. Hey Baldy (and others), thanks for the reply!


    >the words 'server' and 'overclocking' don't belong together, if you are really >serious


    I know! :-( .. The thing is, that the moment I rigged this up to be a server (the MoBo, Mem and CPU were in my workstation before), I clocked it down to normal again, to make it as much a stable server as possible... BUT.. It then turned out that the whole thing wouldn't even boot, being at 'only' 200 MHz FSB.. That is why I returned to my proven (workstation) settings to get it going. While experimenting with different settings I found out that playing with FSB had a very significant effect on stability.. IN THE WRONG DIRECTION!


    SATA Cabling seems ok (at least I found out that the errors keep occurring after disconnection every single one of them..) Also I replaced the PATA cabling, without results.


    MB and Video card.. indeed.. there might be a problem with either one of them, or both. But to my knowledge no explanation for the "Stability-In-Opposite-Direction-Defying-The-Laws-Of-Physics" issue... Hope anyone comes up with a theory!


    Finally, 'Boot' HD could indeed be a problem.. I should run extra tests on it, maybe.


    Have a nice day!



  2. Hi,


    My system has become incredibly unstable since I put together a server from the parts mentioned in my signature. I have put together a server, run on Debian Linux, with software RAID5. Everything seems to be running smoothly, until - about once a week (but it varies between 1 day and 1 month) the system crashes in the most terrible way: All possible errors pass the screen, disks may fall out of the array, etc, etc..


    So what might be the problem? Bad disks? Bad cables? Bad controllers? Bad BIOS settings?

    By now I have replaced a lot of parts by other parts, I have removed the whole array (by actually removing the power cables) from the motherboard, and many other options, but the problem still persists. My conclusion is that the problem must lie with the motherboard, the memory or the processor (or, MAYBE the PCI VGA card.. I don't know, but it is doing nothing most of the time).


    The following characteristics stand out:

    - The errors seem not to be correlated with how busy the system is: it might hang on Idle just as well as on full load;

    - None of the parts is hot, in any way;

    - With FSB settings at standard 200 MHz, the system hangs within a minute;

    - With FSB settings at 220 MHz, the system usually hangs with a day;

    - With FSB settings at 250 MHz, the system seems the most stable: it hangs about once a week;

    - With FSB settings at 260 MHz, the system hangs about once a day;

    - MemTest runs smoothly at any of the above FSB's (the memory is rated at 275 MHz, so one should expect this);


    Current Genie Bios Settings are the following:


    FSB Bus Freqency: 250 MHz

    FSB/LDT Frequency Ratio: x4.0

    LDT Bus Transfer Width: ↓16 ↑16

    CPU/FSB Frequency Ratio: x10.0

    LDT Voltage Control: 1,30v

    Chip Set Voltage Control: 1,60v

    DRAM Voltage Control: 2,80v

    DRAM+.03v if not 3,2v Disabled


    Current DRAM Configuration:


    DRAM Frequency Set (MHz): 200=RAM/FSB: 01/01

    DQS Skew Control: Increase Skew

    DQS Skew Value: 0

    DRAM Drive Strength: Level 6

    DRAM Data Drive Strength:Level 4

    Max Async Latency: 08.0 Nanoseconds

    DRAM Response Time: Fast

    R/W Queue Bypass: 16x

    Bypass Max: 07x

    Well.. Thats about it.. Any help in solving this problem would be greatly appreciated!!! (Unstable servers are a classy lady..)


    Thank you,





  3. Okay, so I bought a little processor update, eager to use the new features. But it doesn’t work! Here’s what happened:


    - Winchester 3000+ runs at 9*250, stable as a rock

    - Venice 3200+ doesn’t boot (keeps rebooting after bios procedures) at 10*200

    - Venice 3200+ does boot at 9*200, but isn’t stable

    - Venice does work fine in a completely different system (Asus A8N-VM CSM) at 10*200

    - I already installed the latest bios on my LanParty (6.00 PG, 06/23/2005)

    - I tried different voltages, starting at default settings, up to about 1.60V (actually 1,25V*1,28 CPU VID Control * CPU VID Special Control, CPU VID Startup Value 1.55V)


    So now I am completely lost. Is something wrong with my motherboard? Are there some other bios settings that have to be tweaked? Most of the settings are pretty much like original (except for the memory, which runs at 3-4-3-8-8 according to CPU-Z).


    Can anyone help me out?!?
