Benefit at running Q6600 multiplier at x9 instead of x8

I'd like to clarify some things too, as I am pretty much a newb to overclocking.

Is 'VCore' the same as 'CPU Voltage'?

The other voltages that are confusing me as to whether to set them somewhere or leave them on AUTO are as follows....

CPU PLL Voltage: options - Auto, 1.70v

FSB Termination Voltage: options - Auto, 1.20v, 1.30v, 1.40v, 1.50v

North Bridge Voltage: options - Auto, 1.40v, 1.55v, 1.70v

Those four voltages, are pretty much what I have in my Bios on my Asus P5K.
Should I move any of those last three, or just leave them on Auto and bump CPU Voltage to 1.45?



I'll put my Vcore(CPU Voltage?) at 1.45, and leave my other voltages on auto then??
And do 3.2(400x8) with DRAM at normal 800.

Does this sound OK?
 
yeah for 400fsb just leave everything on auto and put 1.45v for CPU voltage.after you stable at the speed you want.you can fine tune the PLL voltage to minimise vcore and lower temp and power consumption.
 
I have a question (sorry to high jack). My FSB is at 375 and my memory is rated to run at 1.2ghz (Transcend AxERAM, costs a pretty penny) and is currently running at these settings 5:8, 600.1 mhz 5-5-5-16 2T @ 2.2v. Am I not using this memory efficiently?
 


I'll definitely try that tonight. So if I can get that to run stable in Prime95 with the suggestions you made above, should I try backing the CPU Voltage down a little bit at a time to see if I can get it to run cooler but still stable? Still learning here. :)
 


i would say yes regardless what voltage or timing you are running it on.the real performance of the ram is when they run it in sync with the FSB.jus like a water pipe.

CPU NB(FSB) Memory
water tank=============================water pump

waterpipe

if the is pipe circumference(FSB) is only 375cm the water going into the tank(CPU),it will be limited the flow rate no matter how much pressure(memory speed) is being apply to push the water out the otherside.you will only see a marginal increase in performance.that why you should always lower the CPU multiplier so you could up the FSB to increase memory subsystem performance.

BUT you will really benefit from it if the application is very memory intensive/sensitive.so might as well leave it on the highest multiplier with lower FSB and just sync the memory to it since you wont get much increase if you run it at 800/900/1200mhz.this way you could put less strain on the mobo and memory.
 


i wouldnt do so if you are looking to get the best out of your ram like i said before.but if you only want to run the ram at 800mhz is fine.to be honest with you above 800mhz you wont be able to feel a difference even in game.
 
maybe change the strap to 333 or 400.because above 400(default 266@Q6600) it will limit the memory performance because it will think you are applying the wrong setting to the FSB so it will tickle the Safe Mode for the Mobo.
 


Honestly, what I'm really trying to do is push my CPU to the highest reasonable GHz I can get while running my RAM stock at 800 with a 1:1 ratio.

The 400x8 appealed to me for that reason, as I think 3.6 on air with an Arctic Cooling Freezer 7 Pro is pushing it.

My machine is an audio workstation, not a gaming machine. I want some extra horsepower, but stability is ultra important. Can't afford to be in the middle of a recording session and have the system go kablooy on me. But if I can run my chip at 3.2GHz with no big deal, why not? Currently, I am running at 3GHz without changing a darned thing, has been stable in Prime95 for 9 hours.

 
Is it a better idea to start with my CPU voltage set to my VID (1.325), and then work up from there if unstable, or is it better to start at 1.425 and work down?

And question... what happens if your cpu voltage is too high (what will my computer do if it's too high)

and same question for what happens if cpu voltage is too low.

would a BSOD indicate too high or too low, what about lock-ups/freeze-ups, etc.
 
if voltage is too low then will freeze or BSOD if its too high well you can see it in coretemp and speedfan etc. and it needs 100C before it throttle which before then you would have shut it down already right?

if you feel waste your time work from VID then feel free to do so.you ask us what to do and you just suddenly said feel like doing my way.not very motivating really.🙁
 


???

I'm just a newbie trying to learn, so I ask a lot of questions. Sorry if you took it as me rebeling. lol.

I've just been reading as much as I possibly can and I've come across posts where people have said "start from your VID", so I figured I'd ask and see what you thought about it.

Believe me I'm not saying "I'm gonna do it my way" because I've no idea what I'm doing, that's why I'm here!

So thank you for your help but please don't take offense, because I certainly did not mean it that way. :wahoo: :wahoo: :hello: :pt1cable:
 
Wow, my poor thread! or someones thread! 1.45 was for a Loaded VCore needed for 3.6 stable on your VID chip.

To much VCore causes heat and other damage, so the lower the better. BUT, high voltage wont impact the performance of the chip, it'll just be extra stable!

Look For Load Line Calibration! Turn it on! P5k should support it!

Do the manual test, put the speed back on stock, and then select 1.3250 from the Bios, load windows and see what its at in CPUz, then run prime 95 small ffts on all cores for 1 min and note the lower value. List the two values here. 1.3250 in Bios, then x.xxx in CPUz after booting and idling for a min, then run prime and do the other, and list that new Voltage in CPUz.

Trust me, this helps alot! if you wanna post Bios shots of all the options, that also helps!

This thread is to long, PM me if you need anything, or start a new thread for the others...

sorry maybe its me took it the wrong way:)apologise

lupi remember i have that VID for my Q6600.he will need about 1.4325V(vdrooped) to get to 3.2Ghz.

he did post it there is LLC.you should instruct him what to do since you got the same mobo(the posher version) as him.
 

Agreed. But, a there seems to be a few ppl. who had their CPUs die over at xtremesystems. Those ppl. byw, had like 1.7v on the CPU on water or may be LN2.
 
I like to keep a highest possible ( to a certain extent) so I can extend the motherboard's life. A CPU probably is more durable than a motherboard, and I like to keep my pc for quite awhile.

Anyways, OCing is rather safe because Intel does stress the CPU a lot before shipping it out. It's guaranteed to work at the specified speeds, but since it's been strenuously tested, most can handle OCing. 1.7V, however is bad.
