Overclocking - Wrong CPU Quad Core Multiplier and Clock Speed Report

Published by Jun | Filed under Hardwares

I’ve been tweaking and overclocking my new rig for the past days. From the native 2.4GHz clock i can run it stable to 3.6GHz though need more stress testing if its really stable. The only test i had is leave it overnight running. The highest cpu clock i record is 3.75GHz but its to stressful for the cpu since i increase the cpu voltage around 1.58ish almost 1.6volts and i just use air cooling and not water cooling which is way more expensive to my budget.

If i only have a decent RAM, i believe i can easily benchmark this machine to 4.0GHz. I use 2x 2GB Geil DDR2 Value Series - PC2-6400 DDR2-800 Dual Channel Kit (4GB Total). I hope to upgrade in the near future for a new memory with at least 1066Mhz. This is the bottleneck and hindrances getting high benchmark.

After tweaking it and verifying the system/hardware info using benchmarking tools like Core Temp, CPU-Z, MemSet, SiS Sandra, GPU-Z and 3dMark06 …. i have some wrong nor weird report/results. Check the screenshot below (click to enlarge).

I set 400fsb x 8 multiplier (3.2GHz) in Bios and it shows x6 multiplier most of the time in cpu-z but sometimes it shows the correct x8. It should show 3.2GHz but in system properties and Sandra na it display 3.6GHz. In Core Temp it shows correct fsb and clock speed which 400 x 8 and 3.2GHz respectively.

I wonder whats wrong, i thought after upgrading and updating the Bios of Abit IX38 QuadGT will solve this weird report. Or my CPU - Intel Quad Core Q6600 2.4GHz is the culprit?

Does anyone has same experience as i have?

    Im getting this one too.. I OCed my Q6600 to 3.0Ghz (333×9) Vcore is set to 1.175 in bios (im using a gigabyte P35-DS3P btw)… cpu temp reports the values correctly.. but CPU-Z gives me a multiplier of 6. I turned off EIST already… and EasyTune5 also reports that i have a 2Ghz system with 333×9 settings… weird… :)

    yeah u need to take off speedstep, virtual technology, CE1, thermal control. there might be some other thing but i thhink that will get you set. the cpu is getting throttled by your mobo and to save power, it takes the cpu multiplyer down when not loading on cpu. while this is a great ideo for mainstream laptops, not so good for deskies. i hated that feature myself. i have a Q9450 OCd from 2.66ghz-3.6 ghz stable so far. my ram is bottlenecking my cpu to go further. if i could somehow underclock my ram or unlink it to my fsv, it would be great, then i could easily break 4ghz on air. i know companies can clock the ram so on any computer it will go a certain speed. like sometimes, an 800 mhz ram will be overclocked to 1066 and sold at a higher price. native ram ddr2 runs usually at 1.8 volts. you will notice that 1ghz+ ram is a higher voltage. anyway i would like to find out how the companies clock their ram so its clocked without bios or windows.
