Hi,
I have an MSI K7N2 Delta ILSR motherboard and an Athlon XP 2500+, 2x512Mb
PC2700 DDR all running at stock speeds.
I am able to set the FSB to 200Mhz and the board automatically sets the chip
to run as it were a 3200+.
I have a good CPU cooler and have tried running the system like this for a
day and running at 3200+ raised the temp of the cpu by 4c.
It is fair to say that I have an unlocked CPU however I wish to know how
safe it is to run it at 3200+ speeds permanently ?
Thanks,
NDF |

Hi,
there is a certain code that is imprinted on a black label which is stuck on
the upper surface of the CPU. This code can reveal the date of the CPU and
after a certain date the CPU is *Multiplier* locked. In the case of your
2500+ the *default* multiplier is x11.
So by changing the FSB from 166 to 200MHz you have boosted your XP2500+
(11x166)1.83GHz) to XP3200+ speeds (11x200Mhz) 2.2GHz). The default voltage
(vCore) for this CPU is 1.65v. Even though it's booted into Windows as a
XP3200+ it doesn't mean it's stable. You would need to run something CPU
intensive like Prime95 for 24-48Hours. . . if it passes that then you can be
confident it is stable.
My own XP2500+ @2.2GHz (10x220MHz-FSB) will boot windows fine @1.65vCore
(default) but will fail Prime95 in less than a minute. . . . it needs
1.775vCore to run Prime95 stably . Don't be scared to raise the vCore a few
notches, the only worry to look-out for is *HEAT*. As long as you have paid
attention to your cooling and your CPU doesn't go above 50-60c you will be
fine. . .

Nope... both the 2500+ and the 3200+ run with a multiplier of 11, you merely
changed the FSB. Locked CPUs are multiplier locked, thus you have not
determined whether your CPU is locked or not.

Provided that temperatures are good, and that it's stable, I see no problem.
(Use Prime95 torture test to check CPU stabilty, and memtest86 to check your
RAM)
However, is your RAM and FSB now running at different speeds? That may have
a detrimental affect on memory performance.

Well in fact I tried setting the multiplier to 12x with the FSB set to
200Mhz and the system would not post.
So it would seem although I can get it 3200+ just by upping the FSB from 166
to 200, it in fact is hardware locked to a specific multiplier.
Any suggestions ? |

I'll have to disagree again... 2.4GHz is likely out of the reach of your
processor without additional voltage.

Ok, so if I leave it at FSB of 200 and the multiplier in the BIOS as h/w
default.
The system then posts at 2.21Ghz and WinXP says it's an Athlon XP 3200+
Sisoft sandra reports the performance to be slightly higher than the
reference 3200+, so it would seem performance wise it is working well and is
very stable.
Is there anything wrong with running it like this ?
Apart from setting the FSB to 200 all other bios options are default. |

Nothing wrong whatsoever. I have one here running the same. Perfectly. Has
done for a while now. Run Prime95 in torture-test mode and, if it fails,
give it a slight raise in vcore. I had to up mine one notch.
BTW, I'd say your multiplier *is* unlocked, otherwise changing it to 12 X
wouldn't have had any effect on it. It would still have booted up at 11 x.

if you really want ot see if your cpu is multiplier locked, try
setting it to a LOWER multiplier (like 10x) and leaving the fsb
alone...
otherwise, leave it at 200x11 and like the others said, stress-test
it to make sure its stable |
