help! my new fx55 3800+ only runs 1200mhz!

[cssorkinman]

I have a fx 55 3800 + on a msi k8n neo4 motherboard and the thing only clocks out at 1204 mhz..... bad chip er what?
Any advice would be appreciated
thanks ,
Orkin

it is probably just cool'n'quiet slowing it down. when u play a game or do sumthing else that uses alot of cpu power the speed is increased

 

[sirheck]

something doesnt sound right here?

It could perhaps a chip called an FX 55 3800+.

 

[APieceOfCheese]

Maybe he wanted dual core so he glued an FX-55 and a 3800+ together...

After all the AMD fanboys making fun of Intels glued process? Not wise...

Im confuses you say that you have an FX-55 and a +3800? WFT is going on :?
Check the Cool'n'quiet settings, have you tried OC the chip in the past?

Does it restart randomly? Crashes during game play?

Details son, details. Cant help ya If I dont know What you have under that desk of yours, in your little aluminum tower.

List anything thats associated with your FX-55, from hardware specs to Temps.

I hope he didn't buy it (thinking it's an FX-55) at the previously elevated FX prices...only to find out in CPU-Z that it's a 3800+.

my guess is that its a 3800+ running under CnQ... cuz 1200 is exactly half of the 3800+'s default speed... Fx-55 runs at 2.6... but, yeah, not sure where the fx-55 comes into play then, TBH

No. K8 CPUs run at 1.0GHz (A64 -Socket 939 or Socket AM2) or 800MHz (A64 - Socket 754 or Sempron) at idle with CnQ enabled.

 

[choirbass]

the cpu speed will run at exactly half clock speed when CnQ is enabled (ie X2 4600+ @ 2.4 1.4v will run at 1.2 1.1v when CnQ is on)... however, thats just going by s939... if he has a different socket, s754, or am2... it might possibly be different... the HTT speed however might be what youre referring to though... 1600MHz HTT (800MHz full duplex) and 2000MHz HTT (1.0GHz full duplex)

I have 100% confidence with my answer.

and i have a s939 dual core cpu right in front of me, with amds own cool n quiet dashboard utility demonstrating exactly what im saying

if you change your power settings from 'always on' to 'laptop/portable' you can toggle CnQ usage from on to off, and vice versa...

under windows xp x64:

an X2 3800+ overclocked to 2.4GHz without CnQ enabled, will show as a 2.4GHz dual core processor in my computer properties

an X2 3800+ overclocked to 2.4GHz with CnQ enabled, will show as a 1.2GHz dual core processor in my computer properties

same with overclocking higher, or lower

the same thing is also demonstrated in amds cool n quiet dashboard utility, along with voltages, fan speed, cpu usage, power savings, and cpu temperature changes

same thing with rightmarks cpu clock utility

the cpu multiplier cuts in half, giving you your clock speed... a default multiplier of 10x, under CnQ will then be 5x

 

[qcmadness]

I am sure it is not the case.

 

[choirbass]

not sure what else to tell you... but that is how you arrive at the half clock speed with CnQ

240MHz CPU FSB times 10x cpu multiplier gives you 2400MHz cpu speed

240MHz CPU FSB times 5x cpu multiplier gives you 1200MHz cpu speed

 

[IceBlue666]

I think he should uninstall and then reinstall AMD's Cool&Quiet drivers. If you install it while the CPU is under full load then weird things can happen. For me for example once i installed it while compressning some files and then I got my Athlon 3400+ 754 stuck at 800MHz. Weird huh?

 

[choirbass]

lol, thats not good

You have changed your CPU multipler to 10, i.e. you are running at 240x10?

 

[IceBlue666]

you should also check the cPU multiplier settings in the bios
And there you should select 10x if you have a dual core 12x if its a single core A64 and 13x if it's an FX-55. Hope this helps

 

[Fursecul]

It could be a X2 3800+(2.0 GHZ) or a FX55(2.6GHZ) and it could be runing on C&Q so thats why you are seeing that freq.

 

[choirbass]

nah, my motherboard was cheap (came as part of a combo with the cpu), so, i dont have the option to change the multiplier manually through the bios

you can however change the multiplier with rightmarks cpu clock utility, from 4x to 10x, including half multipliers too... it has a bunch of speed settings on it... but, for my particular cpu, the top multiplier is 10x

but, when i do overclock... what i was giving examples of, is how it works for my set up

So it is normal for you to get 1.2GHz.

Your CPU should have multipler over 10x if your CPU is FX-55 but not x2 3800+.

 

[choirbass]

yeah, exactly

 

[qcmadness]

yeah

Try to set "AUTO" for the CPU multiplier.

 

[choirbass]

no option to change the multiplier in the bios... the only option that has auto is for the HTT multiplier, and that i can change manually, lol... but, for the cpu speed itself, theres no option to, not from there anyhow
