hi all,

OK so I want to clock my Q6600 more than current but I need some info. this is my first Intel CPU in a decade so I dont know too much about it and have been happy running it @ 2.9Ghz for the last 12 months but now i have a processor intensive single core application and need more umph...


I currently have 4 gig of OCZ platinum DDR2 ram
- 800MHz DDR2
- CL 5-5-5-18
- Unbuffered
- Gold XTC* Heatspreader
- OCZ Lifetime Warranty
- 2.1 Volts
- 240 Pin DIMM


Q6600, 320fsb, air cooled, stock voltage. 52oC under load, 35 to 40 @ stock.


looking for info on acceptable voltages/temps for the ram and cpu.
 
crank up that fsb and up the core voltage and away you go!

When you start getting into the higher fsbs you'll need to up the nb voltage too.
 
so far so good.

managed to get to 3Ghz which i have never done before... :) currently 333fsb @1.256v

I have OCZplatinum ram which is doing 420mhz @2.2v

idle temsp are

core0 29oC core1 27oC core2 23oC core3 28oC overall temp 33oC I must say that seems rather low... is speedfan reliable??

had a funny time with the motherboard... its an Asrock Core1600P35 its actually a very good board but lacks NB and SB speed and multiplier adjustment (i miss my old lanparty board), however it makes up for that by being rated to hit 1600mhz... also in the bios I have set the cpu vcore to 1.3v, which for some reason gives the cpu 1.25v (which I think is stock voltage for a Q6600 ??)


just wondering whether to drop the ram divider and go for higher fsb to see what else i can get or to just begin stability testing from here...
 
I am currently trying to get my system running stable too, similar setup, but I have a DFI board and I am finding the sheer number of configurable options mind boggling, most of which I dont know what they are so I dont dare to change them lol. I currently have the core voltage set to 1.29 volts too, 400x8 and it is still unstable for me :( I need to do some more checking in the bios I think
 
I'd say give it a bit more juice and watch out on the load temperatures. Air cooling should be good for about 3.2-3.6ghz depending on luck of the draw. Personally I used to run a Q6600 at 3.4Ghz, I could run 3.6Ghz but the voltage it required resulted in a hefty rise in load temperature on air cooling. You just have to try different settings, despite how scary it can be lol. So long as you have a rough idea of when to stop pushing it.
 
I run 9x400 @ 1.55v in the bios on my board all other options to auto. My temps max at around 72.c under burn test and idle at 28-33.C. Max after 2-3 hours gaming of 55.c.
These cpu,s need quite a bit of V-core to get high clocks. Just keeping nudging it up until its stable.

Yes, but there comes a point where in order to increase stability you require a lot more volts. I believe it is not recommended to go go over 1.5v on that chip, I personally am at 3.6 (400x9) at 1.425v though I am sure I can squeeze a bit more performance from it. Also, be careful of your temps with increased voltage as it has a startling effect on idle and load temps.
 
Mine will post and Run @ 4ghz with 1.6v v-core. Running burn test the Cpu hits 88.c but still runs perfect.. i settled for 3.6 @ 1.55v as it gives the best all round temps to performance. My board under max load droops to around 1.44v.. As said just keep an eye on your temps if they go crazy back it of a bit until you get to a level when your happy..
 
I would also recommend using a variety of burn tests as each one is slightly different in both the total stress of the CPU as well as the method of stressing.
 
Am trying for 3.6 at something like 1.47 now and only getting 30 mins in prime95 test, most of the time i get a error saying prime has stopped working, or sometimes it just locks up or goes on like a browny coloured screen with lines across ?

Temps seem stupidly low for me even after the 30 min prime it was only 58,58,52,52, this on the H50 cooler and Haf case any more advice would be great.
 
Try a bit more voltage, Remember you will get quite a bit of droop with the q6600 so if your giving it 1.4v in the bios your real voltage could only be 1.3v.. Your temps are good. i would use Intelburn test for testing and use at least the high setting. Prime does not work the Cpu as hard as burntest. I have run burn test on mine for 12 hours at 1.55v with no errors. I have even run it for 30 mins at 1.6v @ 4.0ghz it got nice and hot but no damage was done..
I find the H50 to be a bit pants tbh, Make sure you are running your fan at full wack and try using a 2nd for push pull as it improves cooling quite a bit. I think the Q6600 is a bit to hot for the H50 and is better suited to 45nm chips..

Give these a read through:

Overclocking # 1 - Stock to 2.7GHz


Overclocking # 2 - 2.7GHz to 3.0GHz

Overclocking # 3 - 3.0GHz to 3.2GHz

Overclocking # 4 - 3.2GHz to 3.4GHz

Go through them all though as changed settings are incremental. Meaning one setting on the first article may have an impact further down. I never needed to change the NB or pll voltages until i got to 3.6GHz. I've not include the 3.6GHz because things get a bit sticky and one of my cores fail on prime. Still it seems stable enough for every day uses and games..

I will mess its more its the ram speed also, i have Kingston 1066 memory and obviously at 3.6 this would give me 1000, would i really notice much drop going to say 950, i will be happy with anything from 3.4 onwards just want something to push me 5850@900/1200 more.
 
HI,

My Q6600 G0 needed 1.45v in bios which drooped to 1.39 according to CPUz to reach 3.5ghz, seemed to want a lot more volts to go any higher so I stayed at that.

Idling about 35, load about 50-55 with my lapped true (cpu also lapped).

Personally I would be dubious about bumping more than 1.5volts through it on air, not so much because of the CPU but more so because of the north bridge etc. I guess with more butch cooling on the secondary chips you might be able to push it further?

E-I
 
I am going for 3.5 now just didn't seem to want to settle at 3.6, if i can prime95 it for 4 hours+ at this speed i be more than happy, i have actually got a small fan strapped to the chipset cooler now its cool to the touch.
 
Is there a "No Go" voltage on this chip? What would you say would be the highest vCore to put in on the various methods of cooling?

Click to expand...

1.5 or so under air is usually about the highest i would go
1.6 under water.

It's really all about keeping the temps under control. I need 1.62v to hit 3.6ghz on mine but only 1.55v to hit 3.51 which is 24/7 for me. Still quite high but it's a rubbish clocker.
