E4500: FSB 333 x Ratio 9 = 1.800 Mhz?

Hi,

first of all: I'm new to ocing, I've read the guides, got the software and tried to oc my old system first, before wrecking a new expensive one.

My Specs (Aida64):

Motherboard
CPU Type DualCore Intel Core 2 Duo E4500, 2200 MHz (11 x 200)
Motherboard Name Asus Commando (4 PCI, 1 PCI-E x1, 2 PCI-E x16, 4 DDR2 DIMM, Audio, Dual Gigabit LAN, IEEE-1394)
Motherboard Chipset Intel Broadwater P965
System Memory 8192 MB (DDR2-800 DDR2 SDRAM)
DIMM1: GeIL CL4-4-4 DDR2-800 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-5-5-13 @ 333 MHz) (3-4-4-10 @ 266 MHz)
DIMM2: GeIL CL4-4-4 DDR2-800 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-5-5-13 @ 333 MHz) (3-4-4-10 @ 266 MHz)
DIMM3: GeIL CL4-4-4 DDR2-800 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-5-5-13 @ 333 MHz) (3-4-4-10 @ 266 MHz)
DIMM4: GeIL CL4-4-4 DDR2-800 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-5-5-13 @ 333 MHz) (3-4-4-10 @ 266 MHz)
BIOS Type AMI (12/22/08)

Display
Video Adapter NVIDIA GeForce GTX 480 (1536 MB)
Video Adapter NVIDIA GeForce GTX 480 (1536 MB)
3D Accelerator nVIDIA GeForce GTX 480

I still got an QX9650 lying around that I wanted to try later, but if I maybe **** up, I rather destroy a E4500 first.

But for now I'm not even close. My problem: I tried to to OC the E4500, setting the FSB to 333 and the CPU Ratio to 9. I started with 1.375 V, because I read in a lot of threads (kinda hard to find some "standard settings" like "Those values are 85 % of all cases ok!") this is not too bad.

My problem: IMO this should give me ~ 3GHz - but BIOS and Windows gives me only 1.8 GHz??

Ok, check for errors. Loading defaults, went to advanced tab, CPU Configuration, typed again manually "9", disabled C1E Support again, Intel SpeedStep disappeared as it should.

Went back to Extreme Tweaker, AI overclocking Set to Manual, FSB 333, Voltage 1,375 V, RAM manual, 667Mhz, 4-4-4-12 & 2 V.

And... still the same. I read somewhere else, that you could adjust the frequency somewhere else ("JumperFree Configuration"), but the Commando board only allows me (or I'm too blind to see) to change the FSB & voltage in the "Extreme Tweaker" tab and the Ratio in the "Advanced" tab.

What am I doing wrong? Any ideas?

Have you tried just upping the FSB from 200 to say 210 and see what happens? Leaving your multi at 11. Overclocking isn't something you just punch numbers and voltages into and hope it works.

Actually that's what I thought and that it's not just like the lottery and more like math.

If you haven't read the guide here on OCF you should it's very good and should help you understand what you're trying to do. http://www.overclockers.com/forums/showthread.php?t=515316

Welcome to the forum BTW

Hi,

thanks for the welcome. I tried what you said (change values) and *pop* it worked instantly. Now going with 266 x 11 @1.375, making a burn test now.

I still don't know, how 333 x 9 makes 1.800 MHz. I don't want to force that value, but simply understand why. But if I go past 270+ MHz the PC simply turns off after saving BIOS.

It sounds like the system has issues booting at 333x9, therefore it resets the default BCLK to be able to boot.
200x9 is 1800.

Yup, it looks like it resets settings after failed boot. Check memory:fsb ratio 1:1 like 333FSB = 333MHz (DDR2-667) memory and bump FSB and NB voltages +0.1-0.2V.
Can also try CPU ratio at x6 and then check how high will FSB go. When you find max stable FSB then raise CPU ratio without changing anything else ( maybe only CPU voltage ).
