Hey,

A question for you IT geeks geekier than me.
i know a wee bit about overclocking, I just upped mine from 3.0Ghz to 3.6.
How do I fully utilise overclocking? What are the main things I need to make sure match up in the bios?
I want to push it as far as it will go, my mobo is heatsink and made for it so why not use it.

Chur!
Minge

Re: help from all you techies

get some ram cooler’s and even think about water cooling as well.

Re: help from all you techies

got both 🙂 it’s all sorted, just need to know how to fully clock it out. I wanna go to around 4.2 or there abouts.

Re: help from all you techies

Do u have an Asus board? coz they have O/C feature built into bios.

Also depends on your cpu core .. if it is locked or not but u have already upped it so i guess it is not locked .. find out your core then google the rest.

Re: help from all you techies

yea the asus p5q3 deluxe. I was playing with it, seeing what happened etc, I got it to 3.6 after a few trial and error crashes haha might just max out the CPU frequency and see if it crashes my system or not

Re: help from all you techies

ya O/C is just a matter of upping and testing till u find a stable speed.

i remeber O/C an old p1 200mmx that was fun till the cpu fried lol no water cooling or nuffin.

Re: help from all you techies

When overclocking there is often a lot more to it rather then just “upping the Clock Speed”. Other alterations that must be done at times are FSB, and Voltage although be extrememly careful and do everything with “stepping”. One grade a time. If you end up overclocking greater then what you have obviously so far then it may require a voltage increase but only do this in tiny increments for testing. THe best way to test if your overclocking is completely successful. Firstly if your running windows go to Run-> dxdiag – > Enter.

Check what the CPU speed is running at. Then run a stress test (orthos/ memtest / Prime95) which will make your CPU run at 100% for a while. If there are no crashes during it then the overclocking is fine (recommended minimum 5 hours). Otherwise it would be best to lower the overclock. Also check the temperatures of your CPU as well. You don’t want a CPU hitting around 90-100 with overclocking as it will cause physical damage. Cooling is not always needed however if you plan to go the extremes then it is probably a direction to consider.

One of the things you have to consider is your FSB which is very important so if the Core Speed is at 333MHZ and you have a multiplier at 9 (E8400 INtel Example). Then 9 x 333 (approx equal to ) = 3Ghz. Lets say we wanted 4Ghz out of the E8400 so it would be 445Mhz x 9 (multiplier can’t go past this). The multiplier can not be increased past 9 infact to save power it may be reduced to a 6x multiplier however when it is required will push back to being a 9x multiplier. The most “optimal” setup for overclocking is to have your Ram and FSB at a ratio of 1:1. If you are increasing the ram then ensure to increase the voltage of the ram which wil be required if upping the ram.

For overclocking its just keep upping ram frequency and cpu FSB until it crashes at that point its best to lower it back to a previous state which was more stable. Then run one of the stress tests or all 3 above for a long period of time and if it crashes during that time then go lower, ensure after each test you check temperature and that its acutally set by checking through your Operating system, although the readings can also be easily found in your Bios.

Cheers, Racoon – Please correct me where my understanding is flawed, im still pretty noob at it and if you follow closely Some parts I don’t have extensive knowledge on. Hope it helps.

Re: help from all you techies

pardon my ignorance but how is running Dxdiag of any help? apart from showing the current cpu speed? an app like cpuz would do a better job and also give you what your core is and other useful info 🙂 . http://www.cpuid.com/cpuz.php

Re: help from all you techies

It doesn’t acutally particularly matter, and although CPUZ does show what your FSB is set at and your current multiplier Dxdiag is set with all xp machines and will give the result the OS is receiving, so there is definately a use in using dxdiag, although yes I agree CPUZ would be more informative for overclocking depending on what you are looking for also some tools for Temperature monitoring would be

Realtemp (Great for all intel CPU’s) – http://www.techpowerup.com/realtemp/
CoreTemp (Generally for all CPU’s, if using Intel use Realtemp) – http://www.alcpu.com/CoreTemp/

Also please take in mind that 45nm core processors have been known to give incorrect (troublesome) Temperature readings so mostly all the series in the 7000,8000,9000 series). Not saying that they ALL definitely have problems but a lot have been reported to.

Also I recommend the above two temperature reading software over Asus PC Probe 1/2. I was getting a reading of 55 degree (at idle) with it, when real temp and Core Temp both reported on having 35/35 At idle. It also retrieves temperatures on both cores whereas PC Probe only get temperature of a single core. Also With the above stress tests, Prime 95 I have always used for quick and effective testing (smallest app out of all them as well).

Cheers, BR

hey thanks BR, and Stat 😀

yea I had my cpu ratio at 9 clocks, then crept my bus up, it’s now at 470. it was wanting to put my dram at 1881 with that high a bus, but my mobo has a max of 1600 so i turned it down to 1556, to keep with the ratio.
the voltage is all done automatically luckily. good ol asus mobo’s made for o/c make it easy 😀

Those settings sound ok br?
testing time now!

did those tests, thermals and everythings fine. but what is TJMax?

here’s a s/s

TJ Max is the CPU max thorttle temperature and how close you got to it..
With your current results your not running it very safe, you had your CPU run at 98 degrees celsius, In my opinion at that temperature you could have caused damage to your CPU. Ways to Fix it?

1. Use a different Heatsink rather then the INtel stock one – Recommend Zalman Cooler
2. Use a different Thermal Paste -Recommend Arctic 5 Silver

That would make a large difference, where to buy.. well almost all your PC stores should stock those if not ask hicksy Im sure he stocks one of the two… 🙂

But really, its running far too hot, when/if you reach the TJ max (throttle max) your CPU starts throttling so it gets so hot that it begins to throttle and slow down as the electrons, become so over excited (or particles or whatever) that they start a lot of random movement and by doing so prevent the continual SMOOTH flow of electrons through your CPU and then you have throttling of you CPU with data loss and crashing.. IM amazed it didn’t crash and you got awfully close.

Kind Regards, BR

Try setting it back at stock and see what your TJ reaches then at almost 100% CPU usage you should see a BIG Difference.

my mobo is watercooling, it was expensive so it shold be a dam good oneLOL so that should cancel the need for a non-stock heatsink? or would it still pay to get one

if TJMax is the percentage of max temp then it never once went over 50% even though it got to 98c…is that right? or did I miss read what you meant

Intel .. gah .. amd cpu’s run at core temp 50 somthing .. w.o o/c … and amd fan i am .. But for O/C u cant go better .. i have Quad i should try O/C myself … but i dont really need to as i play ET and watch movies n stuff.. i need not for O/C…if i want a better (faster pc i will buy it.) but something u should see…

holy shit lol thats impressive. 5.25Ghz….if only that was doable in a more conventional setting.

I get it now, i was within 2%of maxing out 😯 😯 😯 . so would it be a good idea to invest in a watercooling heatsink instead of a fan heatsink? if so, any in particular that stands out from the rest? and at a reasonable price ? 😀
