I have 2.4 GHz, but CPU works at 1600 MHz ?

[wooptido007]

Hello guys,

I have a intel quad core processor: Q6600 at 2.4 GHz, but it's working at 1600 MHz. Now i want to change it to 2400 MHz ofcourse.

Can some1 help me with this ?

Frequency (Mhz) = [FSB (Mhz)/4] x Multiplier

2400 Mhz = (1066/4) x 9

1600 Mhz = (FSB) x 9; 1600/9= 178 mhz... odd frequency, unless you lowered the multiplier to 6, would fit 266.66 x 6 = 1599/ 1600 mhz.
I don't know if Q6600 have unblocked multiplier, I guess they come blocked.

I don't really understand what you have done with your FSB, but you have to change the fsb of your board to 266 Mhz, in BIOS or on the motherboard, for each of these you have to refer to your m/b's manual.

Q6600 has multiplier locked from above, but not from below,
so x6 is possible for this cpu (also possible variants are x7, x8, x9).

Never noticed... unless you get one, some things don't stick in mind for too long

So, he has to adjust the multiplier.

[Cobracon]

That is an unusual situation since by default the motherboard should set the multiplier to 9x. But, like you folks have already said, a quick - easy fix.


BTW, Dume I like your new avatar. Does it have any deep seated meaning??

Not taken from there though... but the guy who drew it is famous enough to appear on the wiki In fact I'm into oriental calligraphy, looks relaxing.
Just need to stop watching and start drawing!

Our Chinese friends understand what I mean.


I had to change avatar, mine was too close to Leevmaister's. ODPII...

Well, i have a program where you can see some settings of the CPU, and this is what i get to see:

Multiplier: current 6.0x / startup: 9.0x / Maximum: 9.0x / Minimum: 6.0x

My core temp is 27° so maybe i can put it on 9.0x? But how should I do that ? :d

PS: Changing FSB, i really don't know how, i'm a noob in things like that.. I can't go in my BIOS anyway, but can I download a program for that ?

Thanks![/img]

Are you just experiencing the effect of Enhanced Intel SpeedStep Technology (EIST)? It allows your q6600 to 'idle' @ 6x and when under load ramp up to 9x. This saves power and wear & tear on a hen's hindend.

Also, I'm curious as to why you can't access your BIOS.

[kosmokrator]

also u have done the latest bios update to your mobo????maybe the cpu not recognized correctly by your system....

[Bonsai Bill]

Sound like a SpeedStep issue to me. Run a stress program, such as Prime95, and then check your readings while under load.
And usually to access the BIOS you can press DEL or F1 key during the POST at boot time....depending on your MOBO mfg.

[Thandor]

A Speedstep (EIST) 'issue'. I don't think it's really an issue. It more like a good technique to reduce power consumption and heat in your PC system .

Anyhow, to confirm EIST/C1E is working: Download a CPU stresstool like Orthos or Prime95 and open CPU-z. Then start one of those stresstools and see what happens. According to Task Manager your CPU load should increase (to 50% ~ 100%, according to the stresstool. 50% means the stresstool is using 2 of the 4 cores) and in CPU-z you should see the multiplier on 9x and the CPU clockfrequency at 2400MHz.

To disable all this (wouldn't do it, though) you can search for Speedstep, EIST and C1E. You should disable these. Beware: you might have to set two settings. Either Speedstep/EIST and C1E.

thanks!

thanks for everything. I've put my multiplier on 9.0, so now my CPU is @ 2.4 GHz

But i want to overclock my cpu @ 3.2 GHz. Can some1 help me with this??

This is how my BIOS looks like

typ this on google: 'american megatrends main screen' / than the 2nd

But on youtube, where i find many overclock way's 4 a q6600, it's always on this bios:

type again this on google: 'american megatrends main screen' / than the 1st

How is it possible to do it at my bios ?

thanks!

It's not possible to tell you how to overclock the CPU without knowing the exact version of motherboard (and BIOS) you have.
For each motherboard the steps are different. Overclocking can be a very tricky process.

I would like to give a well meant advice -
If you are not familiar with hardware and BIOS don't overclock your CPU !!!

Otherwise you can destroy your CPU and / or motherboard!
If you have luck you will only damage your data and windows on the HD.

With Qwerty .

Please read stuff before you start overclocking. I wrote a quick guide on my website. You can read it here: thandor.net - Overclocking: The basics. In case you want more or different 'food' you can also try using Google and search for 'overclocking tutorial', 'overclocking howto', 'overclocking basics' and stuff like that.

Anyhow, it's best to understand the basics. How FSB, MP, vCore, dividers, stability testing and cooling works. Also think about what you are going to do in case you destroy some thing. Can you live without the PC for a couple of days? If you can't- don't overclock unless you have a 'backup'-PC or something.

Overclocking is like screwing with the engine of your car... if you don't know how to do things correctly there's gonna be fire. So I'm 200% with Qwerty, follow Thandor's link!

There are a lot of good sites that explain overclocking techniques down to the maths behind them... do some research and you'll open an entire world before your eyes

The things you'll learn on those sites will be useful forever on. As for OC, you have cpu, you have Ram, you have Video card, you have the speed on the video slot on the motherboard... It's no just about the mltiplier. You have voltage to increase, means more heat, leads to some sophisticated cooling devices (even water cooling), normal usres that want a boost may stick to less overclock but keep the air cooling (you don't fool around with $$$).


Be very careful and remember that a big mistake could lead to a fried chip, easy as snapping your fingers.
