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

[qcmadness]

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

Updated BIOS?

 

[choirbass]

new enough to support an X2, updated december of last year, but not updated since then...

so, a new bios then to enable the cpu multiplier options you think?

Your CPU is FX-55?

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

Actually madness is correct, and so are you. Back when it first came out, it was at 800mhz then 1000mhz, but now i just looked at the website, it will vary, so your are both correct. Madness a bit more than you, because is not cut by half like you said, but it could be more than 1000mhz.

P.S. copy and paste the whole link, i do not know why is not working by just clicking it.

I don't think 1.2GHz will appear in CnQ tech at stock speed.

There are three states in CnQ:
Idle: 4x or 5x (Depending on socket / A64 or S64)
Transition state: 9x to maximum multiplier
Full load: Maximum multiplier

Unless the HTT is 240MHz / 300MHz, there will not be 1.2GHz as the idle state.

 

[papi4baby]

You just lost me. All i know is what i can read in the website, once you start talking about multipliers and stuff. If is AMD i get lost. Now intel i can understand :lol:

Intel got a similar mechanism but 14x for Netburst CPUs and 6x for C2D desktop CPUs.

well... the stock speed of a s939 X2 3800+ (2.0GHz), under CnQ appears as 1.0GHz, so youre right about it not showing as 1.2

the HTT multiplier of 4X at 240MHz will yield 1920MHz HTT speed (960MHz HTT ddr), just safe enough to not overshoot the 2000MHz boundry

as far as the transitions though, youre right there too... as is my point about the 5x multiplier under s939, again, is where it reduces to exactly half

but, the HTT speed and multipliers and FSB speed and multipliers arent interchangable though... HTT is allowed up to 5x multiplier, and FSB, for my cpu, is allowed up to 10x

you can however, force lower multipliers, down to 4x, and 4.5x, in windows, with different apps

as far as it needing to be at 240MHz to show as 1.2 under CnQ, youre right there too

Yeah, but i know once you guys have to OC, you have to take into account memory dividers and all that stuff. I find intel alot esier to deal with. So i guess you can say AMD is the real man's(geek) cpu 8O while us at intel just pump up the FSB and wooo wow look at that is running at a faster speed(well that was easy)

Once you know how to calculate, it is actually making fun for OCers.

Some motherboards also start at "safe" settings. If so, go into the BIOS and load the optimal ones, if applicable.

FX-55 3800?..maybe he bought it from Micheal's Computers..too bad there wont be any warranty coming with that 😀

 

[cssorkinman]

Cool and quiet was indeed the culprit.... thanks for your help!
The thing would cycle between 1200mhz and full speed during css gameplay, my fps would go from 120 down to bout 40 .. or less. Talk about making things difficult!
Thanks again
Orkin

 

[cssorkinman]

Yes ... fx 55 .... sorry for the confusion.... the place where i purchased it listed it as a fx 55 3800+ sandiego based processor running 2.6 ghz.. and it was being slowed down by cool n quiet to 1200 mhz..... i turned that off and badabing badaboom.... 2772 mhs !
Thanks
Orkin

 

[papi4baby]

Well i would turn it back on, makes the cpu run cooler when not beening used heavily. It will automaticly will clock itself back up when need it, ie games. If it was malfuntioning did you install the drivers for it?

I would steer clear of that store in the future. Pretty bad when they don't even know WTF they're selling.

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.

No. i have a A64 3000+ s754 and it runs at 1GHZ with CnQ.

Amazing...... May I have a look at it (CPU-Z info)?

here u go.

 

[qcmadness]

This contradicts with my hypothesis that the idle frequency is the same as the HTT freq......
