This does not look like a Sempron


Recommended Posts

This does not look like a Sempron 2200+.


CPUZ seems to say it is an Athlon XP-M, not a Sempron.




Please delete or move to the correct class, or is this one of those processors that appears differently in CPUZ depending on the speed at which the benchmark is run?

I reckon CPU-Z has never detected socket A cpus properly, so you I'll have to rely more on the info which the owner can physically read off the actual CPU rather than CPU-Z/CPUID cpu name string

I'll field that question. It is possible to have a Sempron show up as an unknown XP-M if the motherboard is not a NF motherboard and the CPU is bridge or pin modded to a mobile CPU. Case and point, my 2200+ Sempron here.


It's also possible for a Sempron to read as a MP (multiprocessor) if the motherboard or bios isn't coded to actually support Sempron's.


This is actually a huge problem in the socket A categories because it's so easy to work a cheat into the mix. I already know I've been taken advantage of by said cheats, but because of the inconsistencies with CPU-Z there is no real way to prove it, or stop it. Taking the word of the submissour is simply not good enough.

Mr. Scott, that is not the full answer. There are ways to make CPU-Z detect some of the cheats with Socket A ;)

Though, there are more simple things to fix in CPU-Z that's why I'm working on them at the moment.


And there is a way to tell a Sempron from a AthlonXP-M :)

Just need to confirm it works in all cases and add it to CPU-Z

Let me pose a different question then.

In the socket A Sempron categories most (99%)of the SS's in CPU-Z have no numerical designation in the CPU PSN or specification lines for whatever Sempron is installled. Example:


Yet I see a few entries that do. Example:


CPU-Z version doesn't seem to matter because I can find another like the above one using version 1.55 too.

What bothers me is that even with an overclocked FSB, it still reads as a 2200+. Why would it not read higher like the other Athlon CPU's do when they're overclocked? Here's the kicker, this one does:


That's actually a 2300+ Sempron overclocked to 2600+ specs.

Why?, and why does it not work the same for all of them?

Well, that ones pretty easy to answer. The CPU string is set by BIOS. It sets a rating according to Quantispeed formula (if anyone remembers what it is).

If you boot at high FSB speed, the BIOS will read and set rating according to the frequency. But you can boot at normal speed and overclock via Clockgen ;) this will save the CPU string.


And yet there are others ways saying short - the CPU string isn't a source for info, unfortunately.

Yes it is. That's why I suggested to attach photos for CPUs that can't be verified by sure using software. The staff said that they won't accept this.


Still, there is a way to add protection to CPU-Z. And we can work on it together right after I finish at least some of my projects :)
