FACTS AND TESTING: NF7-S 2.0 Shutdown

This just in:

After rigorous testing I have discovered that the shutdown is NOT related to temperature.

Spending several hours, I have determined the following:

Clockspeed:
<font size=5>·</font>2000MHz; No shutdown
<font size=5>·</font>2100MHz; No shutdown
<font size=5>·</font>2200MHz; No shutdown
<font size=5>·</font>2300MHz; No shutdown
<font size=5>·</font>2400MHz; Shutdown

Voltage:
<font size=5>·</font>1.6v - 1.9v @ 2000MHz; No shutdown
<font size=5>·</font>1.6v-1.9v @ 2100MHz; No shutdown
<font size=5>·</font>1.675v-1.9v @ 2200MHz; No shutdown
<font size=5>·</font>1.725v-1.9v @ 2300MHz; No shutdown
<font size=5>·</font>1.725v-1.925v @ 2400MHz; Shutdown on all

Temperatures with SK-7 and 84CFM Vantec Tornado:
<font size=5>·</font>1.6v - 1.9v, 105-116*F (Idle) @ 2000MHz; No shutdown
<font size=5>·</font>1.6v - 1.9v, 106-118*F (Idle) @ 2100MHz; No shutdown
<font size=5>·</font>1.675v-1.9v, 108-121*F (Idle) @ 2200MHz; No shutdown
<font size=5>·</font>1.725v-1.9v, 110-126*F (Idle) @ 2300MHz; No shutdown
<font size=5>·</font>1.725-1.925v, 114*F-135*F (Idle) @ 2400MHz; Shutdown on all

Temperatures with SK-7, 84CFM Vantec Tornado, and a 10,000 CFM floor fan:
<font size=5>·</font>1.6v - 1.9v, 98-107*F (Idle) @ 2000MHz; No shutdown
<font size=5>·</font>1.6v - 1.9v, 100-112*F (Idle) @ 2100MHz; No shutdown
<font size=5>·</font>1.675v-1.9v, 105-116*F (Idle) @ 2200MHz; No shutdown
<font size=5>·</font>1.725v-1.9v, 109-122*F (Idle) @ 2300MHz; No shutdown
<font size=5>·</font>1.725-1.925v, 112*F-124*F (Idle) @ 2400MHz; Shutdown on all


So what does that show?

Voltage doesn't cause shutdown.
Temperature doesn't cause shutdown.

Some form of stop error due to the processor being clocked too high shuts the Abit NF7-S 2.0 motherboard off.

If your board is shutting down, ratchet down the clockspeed. Sorry folks. :sad2:

    Yeah, I was never able to get neither NF7-S v2.0 board to post @ 2.4GHz and both systems run the same CPU: 1700+ JIUHB DLT3C 0310XPMW.

    I figured it was the CPU just couldn't take 2.4GHz.

    Maybe you should talk to about it over on the abit-usa.com forums.
    I'm sure someone know what is going on.

    I think he already knows whats going on. he has the cpu clocked to far.

    Sorry............. lmao

    Precisely.

    I also made this post to clear up a common misconception that I helped spread. Trying to right some wrongs and providing some concise information to the people who need it.

    Others have had less shutdowns, or seemingly more random than mine, so I posted this to clarify.

    Thrax,

    Cpu interface enabled? If so, disable it and it should be different. Was for me.

    Hm... my nf7-s + 2500+ ran smoothly for about 2 hours at 2.4 ghz 1.933 vcore. Then i got the damn siren. Just clarifying that i did get a post. I think i'm going to give my pc another shot at oc'ing... been disappointed lately :-/

    You won't get 2.4GHz out of your 2500. I can tell you that as a fact now that I did this testing.

    Hello,
    I've got same problem on mine NF7-2.0
    But I've noticed that reset happens mostly when i want to run IE on Windows Xp. Then my computer make reset. It looks like someone would push the reset button or that the there was a power loss. I have an Athlon XP 2400+ (not overclocked) and I've had reset about 1 for hour in different situations (ie. playing game, searching web, etc.) After buying an ACAR power system with some filters, the shutdown thing has just dissapeard. I was very happy but .... it still shutdowns sometimes, ad now only when trying to run some application especially IE after a while of not doing anything. For example, i'm listenig for MP3 and doing something in my home, and afres some time (hour or more) I want to run IE, and after clicking on IE icon, system shuts down (to be exact it resets).
    I've wrote to ABIT and waiting for responce, and have read on ABIT's FAQ about putting memory modules from BANK 3 to 1. Will try to move it to bank 3. Hope it helps.

    Best regards

    Woxy

    Have you tried reinstalling WinXP or try Win2k? Is it set to reboot on a fatal error? Since you are not overclocked and you don't get the siren it could possibly end up being a bad mobo.

    Well,
    after reset, system is not set to reboot on a fatal error. It just runs scandisk on hdd's and nothing more (but it always has lost clusters). I'm pissed off becouse I wanted my new PC right now and not waited 3 days for an Asus or Epox. I do regret about buying another ABIT wrrrrrrrrr. Hoped that this time will ROCK after having many problems on windows XP with ABIT BE6-2 and P3 800EB.

    So, what does this mean? That my new NF7-S motherboard won't be able to handle my AMD Athlon XP 2500+ Barton processor?

    what exaclty is the cpu interface ...what does it do when disabled/enabled?

    the 2500+ operates @ 1.83ghz, so it will work. He is saying actual chip speed. All stock AXP chips will work on the NF7-S, its just when you try to overclock them at 2.4ghz or higher you will get the shutdowns (according to Thrax's testing).

    Phew, I thought I was going to have to return the motherboard and pay a restockers fee!

    Gives you A LOT better performance when enabled. A must.

    Oh definitely! According to "RTFM:" (lol)
    When set to Disabled, the system uses the most stable CPU/FSB parameters. If you choose enabled, the system will use overclocked CPU/FSB parameters.

    Sounds like a must-have to me!

    You will notice it in gaming/benchmarks, that's for sure. Run a Sandra memory bandwidth test before and after and see.

    Another weird thing i noticed the other day. I was pushing the voltages a little to see the chip's potential. Runs fine at 2.5+ on 1.94 volts but i want more. So i threw 2.2 volt on the cpu and it booted fine at 2.7 but not stable unfortunatly. The weird thing is that i didn't look clearly what happened but i actually raised the multiplier with .5 by using over 2 vcore. It didn't show in the bios but i could clearly see it on the bootscreen when the cpuspeed was more than 2.7 and i calculated it as well on the calc. I scratched my head and cleaned my eyes, but i wasn't seing wrong. I can still do that if i want. I can't explain it.

    Are you saying this issue applies to ALL NF7-S v2.0 boards? what's your CPU stock speed?
    I was running my XPM 2.0GHz 24/7 @ 2.65GHz (1.84v) without any shutdowns. Now due to summer heat is running 24/7 @ 2.5GHz (1.65v) and still no shutdowns.

    Heh, that post was a year ago, EQuito. :D AMD has refined their process a little since then, as well as making all those nice mobile procs for us too. :thumbsup:

    No, not saying it applies to all of them.

    I am, however, saying that the 5 boards in my home exhibit this same symptom, and also do this with a 2400m chip I've since tried. Default speed is 1.47GHz on the chip I used for initial testing.
