Q6600 at 3.6Ghz

[AirFlyer]

As the title says I got my my Q6600 to 3.6Ghz, which is a 50% over clock I believe. Both my CPU FSB and Memory bus are running at 400Mhz now. So far it seems stable but I didn't really get to test run it yet, does anyone know any good stability testing programs? Also does anyone else have an over clocked Q6600, curious to see what your at.

P.S. Temperature currently for it is 38C.

Is that the core temp?

[AirFlyer]

Using Everest to read my temperatures, it gives me 5 temperatures for my CPU. One is labled CPU and the others are Core# 1 - 4 respectively which all run about 40C, so I assume it's just an average.

[Fulmar]

The 'CPU' temperature is the Thermal Diode that is located underneath all the cores.  And the 'Core' temperature are Digital Thermal sensors that are located on each core.  The 'core' temp is going to be higher.  Either way your temperatures are very good.  You should try and run multiple instances of Prime95 (open the program up more than once - google it to learn how).  When you open it more than once (do it 4 times for your Quad core) you can stress each core at 100%.

Tomshardware.com forums have excellent guides on this - that is if you haven't done this already.

What cooling measures are you using?

[AirFlyer]

Never heard of it but I'll look into it. As far as cooling for my CPU I'm using a ZALMAN CNPS9500 AT(link below) with Artic Silver 5 grease and my Antec 1200 case.

Here is links to software to check stability.  They are from my overclocking site and all the software and utilities have been scanned for malware and viruses.

There is more software on my site available.  The link is at the bottom of the pages under "OVERCLOCKING SOFTWARE"  hope this helps

I received an error code 4 on the occt tool. Couldn't find out what it was because I couldn't read it. I guess I need to download adobe. BTW my comp is clocked at 4.06 ghz and seems fine. However that tool only showed one core. The truetemp showed both cores working.

You need to set it up.  You can go to the OCCT site here http://www.ocbase.com/perestroika_en/ and get what you need.  If your stable this will let ya know.  I seen systems run for days then run OCCT and POOF lockup not truly stable.

4.06 is good what Processor? What temps ?  What voltage ?  Whats FSB ?  Whats memory timings ?  Whats mem clock running at ?  Whats the ration on FSB and CPU ?  What FSB does your MB handle (native OC)Tons of factors all need to be in harmony here not just a high OC of the CPU.  Is your CPU and MEM linked and Sync?  If not you have a bottle neck.

Linked and synched. E8500 I think memory timings are 5 5 5 5 18 (Stock) FSB is 424 x 9.5 multiplier. Vcore is 1.355 DDR2 voltage is 2.25 Highest temp under test is 53c.

Hrm, seems it's a bit unstable at 3.6Ghz even though the temperatures are fine. Kept the FSB at 1600 and set the multiplier to x8 so it's at 3.2Ghz now but still has a 1:1 ratio.

Yea temps are not the only factor in stability.  You asked what others had OV at I have a Q6600 on a machine at the office thats at 3.8 (its a G0 series) actually a touch higher and stable.  Processor to Processor will attain different top ends.  If you can get is stable between 3.2 and 3.4 thats good enough I would say.  Unless you have the hours and hours to get it stable at 3.6 or more.

Is your FSB at 1696 or at 848.  Eith way great settings and voltage on the CPU.  can you get the mem to say less then 14 with a 1t and not a  2t setting?  then it will scream

Wow, I screwed something up when I tried to get Occt to run without error. Everything is at default now. I had it running 4.06 ghz for about 4 months and 3.8 ghz since purchase. Now she's down to 3.16 ghz.

OCCT will tear at a system.  It will let ya know if your truely stable or not without a doubt.  Thats why when some say they OCed to this or that... without a true stress test it does not mean anything.  Find a OC that will handle OCCT for 24 hours then your stable.

What do the codes mean. Where do I find those?

Also, why does it show it under clocked when it was over clocked?
