Who has a Core 2 Quad Q8300? How far can one safely overclock the CPU with only the stock fan? Will buy an aftermarket cooling system later on. Please post your FSB clocks, voltages, DRAM frequencies, Ram cycles, CPU and case temperatures, etc. to give me and others with Q8300 an idea of how far the chip can be pushed.

I have a
- LGA775 G31 motherboard by Foxconn. BIOS allows me to change the FSB clock speeds, vCore voltages, PCI clock speeds, DRAM frequency, and RAS cycles.
- Core 2 Quad Q8300 CPU, with a stock speed of 2,5 GHz per core and 4MB of L2 cache.
- Kingston 4GB DDR2 800MHz Ram, 1 stick with CL5 the other CL6. Does this make a huge difference? Will both default on the worst clock cycle between the two, aka CL6?

So far I managed to overclock the CPU from 2,5GHz to 2,75GHz by upping the FSB from 333 to 370, and upping vCore to 1,28V. Max recommended voltage by Intel is 1,34V. Temperatures still stable at max 59degC under 100% load. Max recommended temperature by Intel is 71degC.
I overclocked the Ram (or rather got it to it's actual speed) from the "default" 533MHz, to it's stated clock of 800MHz, and got the clock cycle down from 6 to 5. On 4 it resets the BIOS.

What were you able to do with yours?
 
A good motherboard will also help with overclocking - buy yourself a 2nd hand P35/X38/X48 mobo on the forums , I can highly recommend An Asus Maximus or Rampage Formula motherboard . I was lucky last year and got Maximus Formula in perfect nick with all accessories for R 600 .

Check out the intel specs for your CPU to know what voltages are safe for your CPU , 1.365v in your case . Set that voltage in the bios and see how much you get from that point onwards , remembering to check temps as you proceed . Try 400 x 7.5 = 3.0 ghz .
 
i managed to get an 8400 up to 4ghz on stock fan and stable benchmarking.
 
I run my T9900 at 3.4Ghz with stock laptop fan when gaming. No problems at all. Only a 400mhz overclock.

got my Q8200 to 3Ghz no problem, but leave it at stock just because I don't need the extra speed, and was merely just testing it out. I'm pretty sure you'll hit 3.2 Ghz easy, but get an after market fan, when a hot day comes after this cold winter, your processor will crap itself.

Nothing to do with this thread but thanks.. What voltage is your CPU at?

voltage is 1.160 and temps 31 Celsius . i thought this was an overclocking thread, whats wrong with my post?
I'm using an after market cooler.

Well it's a Q8300 overclocking thread. What are your temps during Intel Burn Test?

temps 42 Celsius.BTW Im using a huge heat-sink called an akasa venom,my idle temps at 4ghz are lower than they were at stock speeds.

temps 42 Celsius .I'm using huge heat-sink, my idle temps are now lower than they were at stock temps.sorry for the double post
 
downloaded core-temp now idling at 17 degrees how about a competition to get temps below 10?
