I have highlighted the bit wich I think is weired. The model says that it is 2.66Ghz but the speed beneath it says 1.87Ghz.

Also when I run the arithmatic benchmark the results are comparable to a Q6300 @ 1.86Ghz.

I am sure that this cannot be right, does anyone have any ideas?

Thanks.

Its proberly Intels speed step, you can turn it off in the BIOS, also if your running windows Vista change your power setting to performance.
It should then run at 2.66Ghz.

Try searching ...

"That'll be "Speedstep", it'll be reducing the multiplier (and sometimes fsb) of your CPU when the computer is idle or doesn't need more than the performance that it gives with the lower multi. Run a benchmark like Orthos, and keep an eye on CPU-Z and you should notice the multiplier increase back to normal and the Mhz resume back to normal too."

"Disable EIST, C1E & Speedstep in BIOS if you don't want the speed to drop during idle - a must when you are overclocking."

Surely the CPU would not be idle when it is being benchmarked would it?

I just ran it through Orthos here is the result:

1866MHz FSB: 266MHz [266MHz x 7.0 est.]

Great thanks.

Would you be able to tell me why this would be?

I just want to understand a little more about it. Also I don't want to fry anything!

Ok well your Quad was running at 1.8 GHZ right and as you said your multi was set to 7. That would mean the FSB would have to of been 266.

266 (FSB) x 7 = 1.8 GHZ

So to run your Quad at stock you would have to set the Multi to 10.

266 (FSB) x 10 = 2.6 GHZ

So my machnie is currently underclocked??

Oh the irony!

Just to check there is no danger in me setting it to 10 is there?

No dont worry.

All your doing is running your Quad at its rated speed.

266 (FSB) - 10 (Multi) = 2.6 GHZ = STOCK.

only extreme chips are mutli unlocked.....

like the QX6700 etc, not the Q6600.

some mobo's you can lower the mutli on locked cpu's but not higher it.


You say in the bios its "read only", you may have to change a setting to enable it to be changed......it may be on auto.

He is using the QX6700

There is no way my Multiplier is locked is there?
No mate, the QX6700 are designed to run at 10x multi.
Since its the Extreme models, your multi is unlocked in both directions (both up and down).

It should have been set to 10x anyway, regardless of speedstep (surely?)

What motherboard are you using?

i know he has an extreme chip, he was asking if his was locked and I was explaining.....anyways, hope you solve it.....

The MB is EVGA 680i.

I have just seen on their website that my bios is about five revisions behind their current one. I guess I might have to flash to it.

Don't really want too though :(
