Need someone smarter than me

post #1 of 14
Thread Starter 
Can anyone tell me if any of the X2-5xxx processors have multipliers that are unlocked downward? For example: the X2-5000 has a 13x multiplier. It cannot be changed to 12x or any other lower clock multiplier.
Let me clarify. It can be changed in the bios, the option is there, but the actual multiplier does not change. CPU-Z still reports it as 13x as does several other programs.

Are all of the 5xxx processors this way?

All recent (A64) AMD CPUs are unlocked downwards and the FX chips are fully unlocked.

Uh, thats odd. If the stock multi is 13x you should be able to lower it to what 8x or somthing and save in bios.

The Athlon64 X2 5000+ comes clocked at a default speed of 2.6 GHz, but that won't spare it from being pushed faster! With the clock multiplier locked at 13x, the only way to increase the CPU speed is by raising the motherboard reference clock speed.
Why does no one believe this?

That's weird.. Where'd you find that ??

I wasn't aware of that.. I always thought that if the BIOS lets you change it, youre good. And if a chip is locked, it just won't display the option to change it.

Are you sure that you saved the settings, or that theyre stable, and not getting reverted back to stock ?

You should be able to go lower than 13x, just not any higher. Thats weird. I've read about the 5000 going lower.

So now you understand why I'm frustrated and Pe'ed.

Check this out. I set this rig up and was starting to oc it when I discovered this. After much investigation I have determined that it does not matter what it is set at in bios the CPU multi does not change. And yes...I save the bios changes before I exit.
First pic shows the default 13x multi in bios. Second pic shows the multi options available. Third pic shows it changed to 12x. Save and exit. Fourth pic shows CPU-Z and CoreTemp both showing the cpu running on a 13x multi, even though I just changed it to 12x. Last pic shows CPU-Z and CoreTemp both showing exactly the same settings after I went back into bios and changed back to 13x multi.

So is the CPU multi locked, or could it be a bios issue?

That sounds really weird, try clocking it down to 12x but also increasing the bus speed say 5mhz or something and saving it, then check cpu-z if anything has changed. perhaps its messing up changing the settings or something?

For some reason the pics are not getting loaded even though it says they are.

I have tried changing multipliers and frequency but the result is always frequency x13. This started out when i started to find my max HTT, I wanted to take the CPU out of the picture by lowering the multi to 8x.
