lol, thanks :D

I was aiming for 4 GHz though :p I mean, how awesome is firing up CPU-Z to see "4000 MHz"? Or POSTing and seeing "4.0 GHz".

yeap :) . kick@ss oc feeling the same here

in the side note

either my ram or mobo reaching there limit about ~387 FSB

https://www.neowin.net/forum/index.php?show...589658436

so i dont even bother going with my cpu more then 3330

since too much heat to disparate .

so i keep it @ 3.2GHZ

lol the cpu at stock is hell overpower

let alone +800 mhz :D

renmaber the old days when i had 3.2GHZ P4

anything very intesive will make the computer slow as snail ROFL

now even if the cpu hit 95~100 utilization couldn't feel any were as slow down . pure Tech ownage

can wait to oc i7 s' let the race begin shell we make another ocing thread for nahaelm cpus ;)

I overclocked my E7200 to 3GHz with ease (9.0 x 333) but when i tried leaving the voltage on AUTO and going 8.0 x 400, it booted with a missing kernal error (no idea why). I also tried 7.5 x 400 and it did the same thing so i'm wondering if my mobo isn't giving it enough voltage at 400 bus speed? This is my first time overclocking so i don't really want to mess around with things too much, i'm completely happy with 3GHz from 2.53 but i wouldn't mind hitting 3.2GHz either ;)

Awesome, I'll see if I can hit 4.0GHz with my E7200 when I get back from my trip :)

It seems like those with weeks <810 are clocking better.

Sounds like it's related to your FSB and RAM settings. So check that your RAM is receiving the correct amount of voltage for 400 MHz and checking your timings to see if they're the ones defined by the manufacturer (I usually check CPU-Z for this stuff). After that, it would be a matter of adjusting the vNB, PLL voltages, FSB Termination, etc and determining which one will help with stability.

Of course that'll require messing with things, so sounds like 333?9 is where you're at.

The memory timings and voltage is where i get in over my head a bit. I don't want to fry anything...below are some CPU-z screens, perhaps you guys can help me figure out if the timings are correct or not (i didn't see anything on the package when i got the memory).

The Q9450 was cooled with a Noctua NH-U12P and my max temperatures never reached over 66C while using Prime95. I know it wasn't 8+ hours with Prime95 (only 5) but I figured it was stable enough because most of my cores were actually decrease a bit in temperature after that long.

This was my first ever personally built computer as well as overclock. I had the vcore set to 1.4 in the BIOS but idle at the desktop it is showing 1.36 in my CPU-Z screens. This was just the initial overclock as I'm not really sure what I want to increase for now. I think this is capable of hitting 3.5GHZ, but it would take more time and some advise.

My ram isn't at its rated speed (PC8500) but Gwai said don't worry about it because he said it shouldn't matter.

Decrease in temperature != stability. ;) I'll add you in, but you won't be confirmed stable.

Also, RAM rated frequency only indicates that, it's rated for that frequency. You're free to run it slower or faster if you please, neither will have a huge impact on your performance. Pushing higher RAM frequencies than the processor FSB doesn't bring real gains and ends up really just being an extra strain on your RAM and board. That and I doubt you'd hit 533 FSB with your chip. ;)

What are your timings and what are your frequencies? Just check the "Memory" tab.

Alright, when you do so just PM me and I'll make the change.

Thanks for adding to it, we haven't got very many entries...which defeats the purpose of this database (how does one tell average overclockability with two samples?). Oh well.

Finally time for my entry :D

Processor: Intel Core 2 Duo E7200

Stepping / Revision: M0 6

Vcore (Idle CPU-Z): 1.328v

Method of Cooling / Make & Model: Air Cooling, Noctua NH-U12P

Make / Model of Motherboard w/ BIOS version: Gigabyte GA-P35-S3G with F3a BIOS

OS Version: XP 32

RAM Brand, Model#, Frequency & Latencies: OCZ, OCZ2P800R21G, 380MHz, 5-5-5-15

Had it stable for 8 hours ORTHOS, but I forgot to take a screenshot before I took the screenshot of the idle CPU-Z, but then I needed to put a load on my CPU again to find my CPU frequency since I have Speedstep enabled; so it has like 10 seconds on the ORTHOS timestamp.

I don't seem to be able to hit 400 FSB stable with this budget motherboard.

Don't seem to be be able to find it, anyway here's the information on the sticker.

PROD. CODE: BX8057E7200

MM #: 897829

FPO/BATCH #: Q743B000

VERSION #: E37254-001

PACK DATE: 07/03/2008

EDIT: I'm pretty sure it's 743 / 000 for Week / Code.

I got the processor in Hong Kong so yeah, might have gotten an older chip.

Alright, will probably be at work so you'll probably be faster than me.

EDIT: Can't get it stable at 400FSB without going over 1.41v so I think I'm just going to leave it at 1.328v stable with 380FSB.

No one seems to post in this thread for some reason, they all post in the "post your overclocks" thread. Guess the validation is too much for them. :p The other thread is free epeen, this requires work.

that sound reasonable ,

epeen FTW haha

Got you added.

Can you confirm that's the frequency your RAM is running at? The "memory" tab in CPU-Z will tell you that.

Also, for future reference, the week and code can be found on the actual processor die. Doesn't need to be read off of the box.
