AMD Athlon 250 Wont Overclock

LanceGoss47 · 7 Jun 2012 at 15:48

I'm having some wired issues my motherboard is a GA-78lmt-s2p running amd 250.

When I overclock my FSB to 260 Windows says maximum speed 3.0ghz and running at 0.5ghz jumping up 3.0ghz when checking CPU-z it stats im running at 3.9ghz but windows will still say 3ghz and have no idea why the speed keeps changing.

Please Help

running Windows 8 32bit RP

Ok

about to change to 64x

Basically windows shows that like a name stuck with the processor, it's not going to change, and will always show 3ghz, even when it is running faster; e.g. my i7 2600k says "Intel(R) Core(TM) i7-2600k CPU @ 3.40GHz 3.40 GHz" when really it runs at 4.6GHz after some overclocking.
I assume that's what the task manager is showing, Windows 7 task manager doesn't show that but my example is what the system properties shows.

Long story short: Windows says 3GHz as that is what the processor is sold as, it won't change, no matter what speed you run at.

ok cool so do you know why sometimes its saying that its currently running at 0.8ghz for odd reason when its idle.

Saves power and heat by downclocking itself when the speed isn't needed, I believe it is called "Cool'n'Quiet" in AMD's processors, Intel Speedstep in Intel's

It should run at 1040 (4x) when idling at 260 bclock. HT at 2600 is OK, check the memory tab in CPUID and see what that is.

As another member said, it downclocks to save power when it isnt needed, dont worry about it.

Turn the HT down to 2000, you gain no benefit from running it any higher and it will make your system more unstable. If you want to overclock you probably want to turn off C1E and CnQ because it can cause crashes. That might only be a problem with the C2 stepping ones however.

That HT speed also means you are running your NB at 2600 as well, if so, have you actually tested the stability of the system? I'd be very surprised if it could survive prime95 for more than a few minutes unless you've bumped the CPU-NB volts up by about 10%. What sort of cooling are you using?
