At the moment im running my q6600 g0 stepping on

1.4 vcore
8 x 425
851mhz

on a asus p5q pro

what multiplyer should I start looking at for a 3.6 or 3.8 clock
not too sure on north bridge voltages?

its stable and cool at the mo so 3.6 or 3.8 should be easily achievable just need a bit of help

oops the title should read 3.4

im currently testing
8x450
1.4vcore
1.34 nbridge

any problems with those voltages?
 
i thought the Q6600 had a multi of 9? NB is fine, make sure ram is at its rated voltage/timings and work fsb up until it becomes unstable then push the vcore to stable it out again and fsb and so on.
 
the p5q pro can set the multiplyer at whatever you want between 1 and 9 - or isnt that what you meant?

8x450 with those voltages boots fine and gets 10minutes into occt 1 hour test and then says it detected a problem on core 2... not sure what to push voltage wise to try and overcome this?

temps are all good and under 70 - my coolest core is on 40 lol.. looks like I need to lap!
 
Ok first using the 9* means a lower fsb and less strain on bits so would maybe run that little bit cooler with less voltage, also as your running 8Gb of ram then you may need alittle more voltage than normal but i doubt u will need more than 1.4v. Anyway if ur stable and u wanna use 8* then thats fine. For stability testing use Prime95 or intelburn test but it sounds your still pretty stable. Intel burn test will hammer the CPU for like 10mins and will tell you a lot quicker if your unstable but just keep an eye on temps with it as it puts a lot of stress on it so use realtemp 3.0 to watch them. Idk what cooler you have but 1.5v should be fine on a decent cooler but just make sure your memory is kept at or below its rates speed while ur getting the CPU stable. Get CPU-Z to check that. By using the higher multi of 9 then you can drop the speed of your memory while running it 1:1.

Ok thought I should list more about my pc spec so you get a clearer picture :)

Akasa Omega Case
6x 120mm fans 2 are the standard akasa push pulls that came with the case and 2 are the ultra quiet smoked akasa ones with 2 on the side pushing onto the cpu and 2 on the top exhausting

Sunbeam 120mm Heatsink and fan - at the mo its running on non audiable and still keeping stuff really quiet so this can always be cranked up if needs be

Asus P5Q PRO Motherboard

8gb of OCZ ram listed above

7800gtx but soon to be a 4870 1gb toxic sapphire

620watt Cooler Master Moduler PSU

velocoraptor for my main drive and about 4 other drives and a sata dvdrw


9* sounds good then if thats even cooler,
8x450 did just drop me so I upped the vcore to 1.45 and nbridge to 1.36

occt is running the 1h thing at the mo :) highest temp 72 which i doubt it'll creep over and thats with the slow cpu fan speed

ram is at 900mhz...

what difference does clocking the ram make? as is it a case of sacrificing cpu speed to have the ram a bit faster or what?

9x on stuff doesnt seem as friendly when ive tried before but I havnt fiddled too much.

Ive got speedstep enabled so its not clocked 24/7 :)
 
lol I lied - temp got to 77degrees on the hottest and 40 on the coolest so I turned up the cpu fan fully just to see if it'd last out the 1h test at good temps its currently not maxing 67degrees

if this is stable it says to me with lapping i should be able to put the cpu fan back to an inaudiable level ? :D


*edit random question....

on a p5q pro does anyone know looking straight at the chip which corners the cores are in?
 
another q.... im messing about on the internet using my opera browser with this 1 hour occt running at the same time and every now and then my browser keeps freezing up then sorting itsself after 5 - 10 seconds... is that just because my system is under full load or a sign of something to do with the overclock, thanks.
 
You wont see that much difference in the memory speed. Im just saying run it slower while you work on the CPU to take any instability's with it outa the picture. After you have your desired CPU speed and its fully stable then you work on clocking your memory up. Iv never used that Occt stress tester as most here use Prime or IBT.
 
Ive heard a lot of peeps swear over occt, I'll prime it overnight if it passes occt

since it seems dandy at 900mhz now if its stable thats cool with me i'll just prime it and if thats ok i'll knock down the voltages to as low as I can stabilly.

not bothered about 3.8 now as I think that will be too hot without water after seeing these temps and I want a silent overclock so 3.6 after its lapped should be silent :)

Im considering ziptieing a fan onto my northbridge to keep it cool - is it worth the hassle do you think?
 
depends if its getting hot. You can always try lowing the NB voltage after you have done the same for the CPU till you become unstable then knock it up a notch.
 
damn occt failed 1 second off the 1 hour test on core 1 haha :D I just found a thread with people saying they get 3.6 with a 1.5 vcore stable... dont think I really want to be playing that high in the vcores, might just settle for a silky cool 3.4 after all this haha :D

would the difference between 3.4 and 851mhz and 3.6 and 900 mhz be minimal? I do a lot of video rendering but it needs to be solid.
 
Last question promise :D whats the advantages and disadvantges of running 1:1
What you said about the 9 multiplyer sounds good but 9x375 will give me 3.4 meaning my rams at 901mhz which is cool...

but thats 5:6

or I can do 8x400 and get 851mhz ram and thats 1:1

which is better?
 
No the q6600 runs on a 9x multi great clocking cpu, but pushing a q6600 is pretty hard, i done it with mine, but it involved lapping my cpu and my TRUE black cooler and 2x2000 rpm fans to get to 3.8ghz, which is more than enough for any modern system

here is a part of my review on the asus rampage formula x48 i recently bought

"my settings in bios 9x400 fsb, ddr2 1000 5,5,5,18 volts are cpu 1.43v fsb 1.5v memory 2.1v i would not dare changing the other volts as i don't know what they are for so set to auto.

ran everest torture test for 10 minutes, came back & here are the temps.
mb 33c
nb 55c
sb 45c
cpu 44c
core 1 48c
core 2 47c
core 3 40c
core 4 42c

idle
mb 30c
nb 49c
sb 42c
cpu 25c
core 1 29c
core 2 28c
core 3 25c
core 4 27c

this is with a TRUE lapped perfectly flat & a perfectly flat lapped q6600 G0."

excellent temps at 3.6 and really stable, it is the highest i have pushed for on air, managed 3.8ghz when i used water cooling for a short time, but my temps now with air are better than the water cooling i had set up, does anyone else know what tweaks might be needed to push for 4ghz from anyone with experience, hehe i'm too lazy to notch up small amounts would be great if some one knows already, i know it varies, my q6600 on stock clocks only needs 1.2v i must be lucky :)
already know what fsb would be needed 9x444 but have no idea how much higher the volts would have to go on average if there is an average
 
This is mine on my daily clock of 3.6ghz,

untitled-1.jpg


Ive been upto 3.8ghz, 8 hours prime stable, but dont really need that speed for normal use.
 
the main reason i want to push for 4ghz is to see if i get better performance in gta IV, not for 24/7, i'll have a mess around with it :)
gta iv is by far the most demanding game i know of so far, i'm trying to find a reason not to upgrade to i7 :)
 
can someone answer my question above please and also tell me why i should use 9 and not 8 multiplyer?

Last question promise whats the advantages and disadvantges of running 1:1
What you said about the 9 multiplyer sounds good but 9x375 will give me 3.4 meaning my rams at 901mhz which is cool...
