multiplier stuck on 9

Basically i change my multiplier in bios and save it. Then i load up my computer and the multiplier is still 9 and if I change it to a different value it is still stuck on 9.

I am overclocking a q6600 on a abit ip35 pro.

So it is always 9 what ever value I change it to. Any ideas?
 
The maximum multiplier for a Q6600 is 9.

9 x 266MHz (Front Side Bus speed) = 2.4GHz.

If you want to overclock you can only do this by increasing the FSB not the multiplier.

For example 9 x 333MHz = 3GHz.
 
That's the problem I've got with my E8400 - I'm stuck with a max multi of 9 meaning I have to ramp up the FSB to annoyingly high levels to hit decent clock speeds

To get 4.0GHz I've got the fsb on 9x445!

Which ofc means you need expensive very good boards.
 
Sorry guys I mean i cant change the multiplier to a lower value. I set it to 8 save and exit. Open bios it is still on 8, however in windows it reads 9 (cpu-z) What is the name of cool and quiet in bios?

Why would you want to lower the multiplier if you want to overclock?

If you lower the multiplier to 8 you'll have to increase the FSB to 300MHz just to get back to stock speed.
 
Look out for something called EIST (I think that's Enhanced Intel Speedstep Technology or something similar...) That's what it's called on my mobo

Bit if you can't change it at all, I'd recommend clearing the CMOS by taking the battery out for two minutes then pop it back in and it should all be at defaults - then you can change it to what you want it and all should be good :)

My q6600 is more stable on a x8 multi and a higher fsb. Don't know why but it won't budge above 3.2ghz on x9 without throwing a flid.

It's not so bad with the q6600, ii run mine at 8x420 for day to day use, which is just over 3.3ghz.

Info: Some people choose to lower the multiplier so they can use a higher FSB speed which generally speaking, offers better performance than the same speed using multipliers. Intel normally set a maximum value but allow you to reduce this figure.

The chap with the e8400: Why would you think your fsb is too high? Sounds pretty reasonable to me.

Providing you have the desired CPU frequency with SpeedStep turned off then I would ignore what cpu-Z about the multiplier.

You also mention that your q6600 throws a barnet when overclocked.. Have you tried increasing the vcore just very slightly.
to 1.3v say?

The multiplier does change from 9 to 6 because of speed step! However even when i change it to 8 in bios and say clock it to 400mhz aiming for 3.2ghz my p.c dies because the multiplier is stuck on 9 making it 3.6ghz.
 
but you said in BIOS it still reads 8??

just for now, stick with the 9 and decrease the the FSB to 378 and a vcore of 1.4250v (assuming you have a decent cooler) what happens then?

Disable Speedstep, CPU Spread Spectrum and PCIE Spread Spectrum.

I am happy to stick with 9 to be honest just wondering if there was an easy fix to reach higher clocks. Before my psu died i was hitting 3.6ghz on 8 multiplier and cant reach it now.

If you see this thread:

Think I need to sort my cpu cooler before i attempt 3.6 on multiplier 9

Keep an eye on your temps, if you start hitting mid 70s during a stress test, You are getting a little bit warm. 80s and you need a better cooler. Also there is no reliable way of monitoring north bridge temp, so if you over volt your.nb,to stabalise a high fsb, I run my p35 nb at 1.4v, finger test the heatsink, if it's burning up then back off a little. The nb will always get warm, but if it gets painfull to touch, its too hot.

As you said, my quad seems happier with an 8x multi, its a high vid g0, and so is generously over volted on both cpu and nb. But temp is critical, if it starts getting toasty, back off and re access the situation.
 
Also, forgot to mention, high level windows hardware monitors are quite often wrong for various reasons, try going for 8xmulti and a 420 fsb, and check the cpu speed with cpuz and a couple of other free monitors, if it still says 9x multi, but displays the cpu speed as 3.36, then you know it's an issue with the monitoring tool.

My vcore is 1.5**v which is higher than recommended, but temps are good, it's been running at that voltage for a few years without issue, but temp is critical.. if its too hot, back off.
