Athlon XP-M 3000+ on Asus A7N8X and overclock/rating

jamesjameson · Guest

Hi again guys!
CPU is on the socket running! Smile

It seems to work well at 200 MHz x 12 = 2.4 GHz! Smile

Now I have to test it well to understand if it is really stable!

1) Can you help me testing it? What software can I use to test it? Is it CPU Stability Test a good software for it?!

2) I set DDR RAM at 200 MHz (real 400 Mhz FSB) but booting PC, in initial post page, I read 199 MHz! Very Happy

And I also see that CPU frequency is effectively 199 MHz x 12 = 2388 MHz!
Can I try to set FSB and RAM at 201 MHz?! Just to read maybe 200 MHz?!

3) an other thing: My motherboard show me at the boot "Unknown CPU" but it seems to work fine... is it OK?! (the same from Windows 2000 OS)

Thank you guys! Smile

The 200.5 is caused by a ±0.5% FSB tweak motherboards use to make things more stable... I forget the term, but it's normal.

Benchmark it with SuperPI.

Also, "Spread Spectrum" is the word I was lookng for Razz

jamesjameson · Guest

Hi guys,
it is some time I don't write here answering... I runned SuperPI but I decided to not publish results because I have some strange stability problems... I try to explayn!

(1) When I run SuperPI o CPUstabilityTest it is all OK!
Test are right and I have no stability problems under big long CPU stress, the same doing hard video file divx conversion...

(2) If I just watch a stupid, simple flash video on Utube instead, video often freezes, screen becomes black and then my computer desktop appears again in a few seconds and it seems all working good again! (putting mouse pointer on the task bar at the bottom of the desktop when video freeze helps screen becoming black and turning then back to normality).
Just only video view disappears.. I can execute commands, click links, open programs when it is black (I need a lot of imagination!)!

It seems absurd, it seems new processor running very good by tests under high stress... I thought to SVGA card or RAM:

(A) I put on a more powerful fan on VGA heatsink; it is summer now here (30 °C in my house!) and the old fan had some problems but I did not fix the problem so, surely VGA live better anyway, before it was like burning! Smile

(B)I thought that I changed from 333 to 400 Mhz FSB but AGP should run at 66 MHz because it is in "auto" mode and so it should automatically run at 200 MHz / 2 = 66 MHz.
I tryed to put it fixed at 66 MHz and there is the same problem again.

(C) DDR RAM is 400 MHz DDR certified with passive heatsink and I remember that I tested it at 400 Mhz after I buyed it!

PS: I know that these probles can come from not sufficient power source (I had the same problem with an other PC) but I changed my power pack only 1 month ago with a good powerful new one and all runned good, I do not want believe that this CPU could ask much more power that the original XP 2800+ and SVGA need some more power to run well!

I'm not sure that your problem is in hardware. This could be a video driver problem. Try to install the latest drivers for the video card.

I am running my AXP-m at 1200Mhz, 200x6, and it's happy as a clam at 1.1v Very Happy

Passive!!

Continue from above, some other tests... I think this is an hardware instability, I try to explain:

I wrote that CPU run well and stable at 200 MHz x 12 = 2.4 GHz (testing by CPU stability test, SuperPI and divx conversion)

(1) Anyway I tryed to underclock CPU to try to understand the problem: I setted CPU running at 200 MHz x 7.5 = 1,5 GHz very much slower than original standard frequency...
I have the same video freeze problems, there are no CPU instability like tests confirmed me before... Smile

(2) Then I put it at 166 MHz x 12 = 2 GHz ..... ALL OK, THERE ARE NO PROBLEMS SO! Shocked

It seems the problem is about the FSB too high (200 MHz)! Rolling Eyes

I really do not understand! Where is the problem?!

PS: before changing CPU I had no problems with video driver, today I will try to load an old running HD image so I will be sure if they are bad video driver...

More tests... Shocked

My motherboard (ASUS A7N8X) permits to set FSB from 100 MHz to 250 MHz in steps of 1 or 5 MHz so I started from 180 MHz and rise up in everytime smaller steps...

PC works well until 195 MHz FSB, I have some very small problems at 197 MHz FSB! Evil or Very Mad

So my limit seems to be 195 MHz... ok, not so bad: with the 2800+ it worked at 166 MHz!

Moreover I felt that South Bridge was a burning fire on my finger... googled a bit "a7n8x south bridge" ... here it is the problem and the solution!!!!! icon_yikes

Hmmm,
the man that wrote the South Bridge Voltage modding article in the link above tell he has "a Nasa solder certificate and the right tools".... icon_yikes

I have not... I am not able doing it... icon_headache

I think I will stop at 195 MHz, I drink too much beer to solder that!

Thank you for all your help friends! Smile

PS: this problem is normal in most Asus A7N8X Revision 1.04/1.06
