Q9550 Overclock

[JHONO]

Just realised that my Q9550 Was default clocked at 2.0 GHz When its suppose to be 2.8. Anyways not to worry its sorted out now and back to 2.8GhZ with a multipler of 8.5.

Thing is i want to overclock further using the ASUS Extreame Tweaker in the BIOS. Want to try and reach about 3.2GHz if possible, but i dont know if i need to start messing around with voltages which can be risky.

Anyways heres a screenshot my CPU-Z:






Also want to get a 1.1 Ratio as well with my CPU and RAM. What sort of voltages and other changes are required to do this?

Thanks

Thanks Guys. Can i just ask how will i know when it becomes unstable? and how much is 5-10% lets say mayby increase FSB by 10 Mhz at a time then try?


Thanks

Hi m8 just had a bit of problem then. When i first clocked it to 2.8 GHz it doublebooted then loaded windows, then i restarted and the computer just hung and the screen went blank. I had to reset the BIOS to fix this.

Could this be due to the fact that its over volting?


Thanks

Do post those BIOS voltages

 

[JHONO]

The Voltage at the moment is on auto, but according to CPU-Z its 1.200V

 

[JHONO]

Thanks for that. Thing is though did you manually set the voltage to 1.200V thats what mine is on auto now? and im having problems?

Thanks

 

[JHONO]

At 3.4GHz now voltage at 1.168 now what about RAM its running at 850MHz what sort of voltage would suit this? 2.1V?

Thanks

Take a look at manufacturers website, my OCZ is good up to 2.1v but is varies with manufacturer , also check the nb and sb voltages there on my screenie, all voltages were set manually in the bios and i also have loadline calibration disabled as well as all the 'spread spectrum' options

Remember the more volts you put through, the more heat

Yeah thanks for your advice m8 its very good. Just stress testing now with SP2004. I think my memory voltage is ok at the moment its on auto but if its not causing any problems then i think its best left.

Also are you saying that i should lower nb sb voltages to lower temps? or to increase performance?

Im still a noob to the overclocking world m8 but im gradually learning more as i do this and from good advice from the people on these forums and yourself.

Also whats loadline calibration and Spread Spectrum? lol Heres a screenshot below of SP2004



It says that the CPU is clocked at 2.6GHz with a x6.0 Multipler when obviously its clocked at 3.4GHz x8 multipler on CPU-Z and Everest?

 

[JHONO]

Yeah thanks i thought that as well, Dont mean to sound stupid lol, il take look at those.

Thanks

here u go

got everest running , if you look on the sidebar you can get all voltages and fsb settings

Hi m8 Changed my Voltages to what i think, and ran prime 95, was stable at these settings (shown below) for 6 hours till i got an error and the computer rebooted. Is 6 hours enough to prove its stable?




Also my voltage is set to 1.21250V in the BIOS but its says only 1.8 on CPU-Z and everest? is this something to do with Vdrop or Vdroop? how do i sort this?

Thanks

 

[JHONO]

Hi m8 thanks for your reply. I have LLc on now for about an hour and so far no crashes ect. I think il be turning it off soon after reading that artical.

Anyways with LLC disabled, i tested my system with prime 95 and it was stable for 6 1/2 hours before it rebooted, VDROOP was apauling it dropped from 1.8V to 1.5 underload even though its set to 1.2125 in the BIOS which as you say probably caused the computer to reboot.

Is 6 1/2 hours decent for stability even though LLC is off, i think it will be more stable now after that than enabling it and getting BSOD's?

Also took note of some of the voltages off your screen shot, they aint that high are they which is good? Even though youve got LLC off is your computer stable?

Thanks

 

[JHONO]

Cool. Just dont get how you dont use LLC and your voltage is 1.2V Do you not even suffer from any VDROOP what so ever?

So far Prime 95 has gone 8 hours stable with LLC enabled. Surely you must have your idle voltage set high in the BIOS then it VDROOPS to 1.2. I thought this was a problem in all Rampage formula motherboards?

Thanks

Hey yeah i see what you mean. My voltage is set to 1.212V in the BIOS with LLC enabled, it shows as 1.2000 on everest, so theres still a bit of VDROOP.

Thing is with LLC it sticks to 1.2000 idle and load, its pretty good, also ive had no blue screens whilst idle with LLC enabled as this was a common problem. 15 hours prime stable with it as well

Seems its not all bad after all. VDROOP is almost eliminated, although im still watching the computer when its idle to make sure im there if theres a problem.

Thanks
