It says that my multiplier is always at 6 as well, and its just not true - with any other program i have used it comes up as 9, including the bios.

Bottom line - CPUz has bugs...

Please don't type things that are incorrect. CPU-z doesn't have bugs. It's just the accurate way it checks and reports back to the computer.

Well, maybe i am wrong... but it doesnt make sense as my multipier remains at a constant 6 in CPUz no matter what im running...

When booting up CS2, it goes to 8, but then back to 6, does that mean my processor is doing its job well?

That's EXACTLY whats supposed to happen.

You can actually Disable the setting responsible for changing the clock speed of the CPU.

Using this Guide:
Core2Duo Overclocking Guide v1.1
you can get the most out of a CPU by doing the following:
1. Disable ‘AI Tuning’ for ASUS, ‘C.I.A.2’ for Gigabyte
2. Set PCI Express (PCIe) frequency @100Mhz (‘Auto’ for DS3/DS4/DQ6)
3. Set PCI frequency @33Mhz
4. Disable Hyperpath 3 (for P5W DH only)
5. Disable any ‘spread spectrum’
6. Disable Q-Fan (for ASUS only)
7. Disable ‘Limit CPUID Max to 3’
8. Disable any overvoltage protection
9. Disable ‘C1E’
10. Disable ‘EIST’
11. Disable Virtualization Technology
12. Disable No-Execute Memory Protect
13. Disable any other thing you don’t use
14. Do not enable any speed enhancements you see

I believe the EIST and C1E settings are most relevant to the changing Proc speed during different types of load..
Disabling them would mean the CPU will always run at set clock speed. Which for that Proc is 8 X 266.25, I think.
Thats only part of the guide.
I suggest you follow it from start to finish.

oh my bad...i was thinking of locked max multipliers, but those can be changed though

You can lower the multi on most procs but not increase it.
Which may be useful if certain speeds/settings aren't stable..
Instead of 9 x 400 for a 3.6 GHz clock you could do 8 X 450, or even 6 X 600, for some examples..

Ok, well how much of a differnce will I get with overclocking me 6420?

peterhuang913 · 07-01-2007, 01:34 AM

should be a noticeable difference

And what STE said, is what I should to to overclock it?
