775 Overclocking problem

CubiX

Go to solution Solved by CubiX,

If you want to overclock effectively you'll need a higher grade motherboard. Asus P5Q series boards based on the P45 chipset are very commonly used by members on this forum. I've also had success with ECS P45T boards and Asus P5N-D boards based on the nForce 750i.

My personal favorites are nForce 790i boards like my EVGA 790i FTW, but they are very hard to find nowadays. 780i boards were finicky with Quads, but were excellent too if you want to stick with DDR2. P45 boards are available in both DDR2 and DDR3.

Well thanks for your help :P I did consider changing my mobo a few years ago but welp i will probably be upgrading to intel's next gen cpu's :P

Hello guys ^_^ i wanted to ask a question :P

So my Q8300 will not get to higher frequency (will not boot) unless i raise the pci frequency... voltage hasnt been a problem.

The thing is that my system is stable with up to pci freq @120mhz from 100mhz which means that unless i raise it more, i cant brake my 413mhz fsb oc 

However if i raise it at 121mhz (pci freq) my drives will not be detected (yes i know pci freq affects drives pci lanes and other devices) but the thing is... how did guys archieve 4+ghz when i can only archieve 3.1ghz ?  Is there any secret with the pci frequency that i don't know ? 

Some help would be really nice ^_^ 

Thanks for your time

What motherboard are you using specifically?

An overclock with a Q8300 is more often than not done with the FSB, and this gets tricky if you can't unlink it from your RAM. PCI frequency isn't a good idea, ever.

Sooo my problem is that there are no inlink settings (asus p5e vm-do) .. I dont really like messing with the pci freq either (enen though it works) but only if i raise it i can oc... Else it wont boot no matter the voltage...

And even then i can reach max 3.1ghz with 403mhz fsb 1.05v and 120mhz pci freq

Should have quoted me or tagged me I would have seen this sooner.

Anyways if your board doesn't have an unlink option then your FSB settings affect your RAM speed as well as your CPU. This will decrease your overclocking headroom quite a bit.

Your board is a Q35 chipset, it's meant for business workstations, ie stability. Therefore it's not going to be as effective at overclocking as a P35 or P45.

Yeah i know that :/ Well as for ram oc i have no problem ... its running fine w/o heating up that much at about 800mhz

So yeah ... that is the only thing that bothers me :( no unlink options so that i can oc even just a bit higher (yes indeed this is a q35 chipset)

So much headroom Q.Q

If you want to overclock effectively you'll need a higher grade motherboard. Asus P5Q series boards based on the P45 chipset are very commonly used by members on this forum. I've also had success with ECS P45T boards and Asus P5N-D boards based on the nForce 750i.

My personal favorites are nForce 790i boards like my EVGA 790i FTW, but they are very hard to find nowadays. 780i boards were finicky with Quads, but were excellent too if you want to stick with DDR2. P45 boards are available in both DDR2 and DDR3.

Well thanks for your help :P I did consider changing my mobo a few years ago but welp i will probably be upgrading to intel's next gen cpu's :P

Yeah that's usually the best course of action. :P

Sometimes it's even cheaper too.

Personally my 8300 didn't overclock well but I was able to through the FSB, think it was my motherboard though since it has a chipset problem. Try leaving the voltage and going up on the FSB, comes down to what the motherboard is also since that will play a roll.

A shadowy flight into the dangerous world of a man who does not exist.

Thanks for your time 

honestly that is quite impressive oc for that chipset! you will need a better board or high multiplier cpu to get more performance now.

Well i didnt even need to get my voltages higher than stock... i actually dropped them because honestly at 3.1ghz my 8300 barely needs 1.1v (unlike my q6600 which sucks my neighborhood's electricity and my pocket as well... (it needs 1.45volts to reach 3.5ghz :/  ) but anyways the chipset on my mobo is what really limits me anyways (if only i had a better mobo, i would expect this 8300 to reach 4ghz @1.4v and i would even try to push it further :D )
