So, I thought I would try and squeeze a little extra juice out of my rapidly aging system
At the moment I have a Q6600(2.4 @ stock), 2gb ram (1066 speed), and an 8800 GTX. Now its a modest system by todays standards but to be honest I can run pretty much anything on high (albeit turning off vsync and turning shadows down)
So I read the manual for my mobo (evga 680i) and followed the guide, fucking no luck.
My Q6600 is the g0 stepping model which apparently is "easy as fuck" to overclock, infact most sites are saying with that mobo and the stepping model you can "easily" overclock to 3ghz on stock cooling.
well I tried 3ghz on stock cooling and it gets to the windows loading screen and then reboots, Ive tried so many combinations and it does this 99% of the time, gets to starting windows screen and then will reboot.
The only combination I have found that is fairly stable is setting is as follows
FSB set to 1200 with a x9 multiplyer (= 2.7)
cpu voltage at 1.3000
cpu fsb voltage at: 1.3
others on Auto
memory unlinked and running at 1066
this is stable(ish) I ran prime95 for 20 mins and it never crashed (though it did go from 55c up to 87c during the tests, seemed kind of hot but it held out) Im never using full mem and 100% on all four cores during anything so I hope it holds out.
believe me if i try anything than those settings It reboots at the windows loading screen. So anyone got any tips on how to push this to the "easy" 3ghz, its pissing me off.
any help appreciated
Im also trying to overclock my Q6700, i barely OC it at 2800 mhz and the cpu get up to 70 degree at load and 50 degree idle, something is wrong, i dont now much about that much either.
well glad we sorted that out, lol.
its driving me mad, now Ive crashed so many times at the windows loading screen that my welcome screen can hang for upto 5 mins before booting into windows.
which stepping is it
maybe raise your voltage a bit? my q6600 g0 overclock @ 3.2 GHz runs on 1.4V
[QUOTE=Jaehead;26277908]maybe raise your voltage a bit? my q6600 g0 overclock @ 3.2 GHz runs on 1.4V[/QUOTE]
believe me Ive tried, cant even get it to run over 2.7. Ive upped the voltage one by one, pissing me off now

well damn that's the one that normally does 3.2 GHz on stock cooling. what motherboard do you have?
Also maybe it's just my preference, but I would watch that temperature a bit. For me, I would never let my CPU go over 70C, and that's during stress testing.
set voltage at 1.5 and see how high you can get the FSB
[editline]25th November 2010[/editline]
actually, what cooler do you have?

I try to keep mine under 50C load, but I'm playing with a different sort of beast
How can i know what Stepping/revision my Q6700 could have, because with a stock fan and stock voltage, im at 50 degree idle at 2800 mhz (2666 stock)
Try lowering the RAM frequency to 800 or 667 mhz and try again.
I will try that binary, but what about voltages?
If you meant RAM voltage, it won't matter too much if you are going to underclock the RAM anyways. If you want, you can push it a notch or two for stability. If your motherboard have such option, I would also push the PCI-E clock by 10-20mhz or so, it will help stabilize GPU overclock A LOT, as well as CPU overclocking.
I also own a stepping B revision G0 Q6700, but why is my CPU frying like that? 55 celsius and 70 celsius at load, it hurt.
probably shitty thermal paste and/or cooling
its just stock cooling, i tried what was mentioned earlier, but alas it reboots at the windows starting screen.
what is causing the reboot, if I could pinpoint the problem ie: is it the ram? the voltages? it would be easier
Make sure your PSU is up to the job. Overclocking raises the power demands by a lot.
Personally, the way I'd do it is to slowly raise your overclocks without raising CPU voltage. Go as high as you can 'stock'. At this point, note your overclock and temps. IF, and only if, your temps are okay and you still have room to go higher(ie your CPU is known to go higher) then you will be ready to start raising CPU voltage a little at a time.
Not all CPUs overclock the same, I have a very similar problem with my Q6600. Just like yours it is B stepping and revision G0 but no matter what I can't push it further than a couple hundred MHz. The only thing I can think of is that when the batches of CPUs were made mine (and possibly yours too) just met the testing requirements. This explains it a little better (from [URL]http://features.techworld.com/personal-tech/3228469/a-simple-guide-to-overclocking-your-cpu/[/URL]) -
[quote][B]Myth #2:[/B] [B]Different iterations of the same chip have the same capacity for overclocking.[/B] Because the manufacturing yield is a statistical distribution, you'll probably get a CPU that can run much faster the listed speed, but you might end up with a processor that runs only about 10 percent faster. Consequently, the fact that your buddy down the street can run a Core i5 750 (rated at 2.66GHz) at 4GHz doesn't mean that your Core i5 750 CPU can will be able to run that fast. That caveat is well worth keeping in mind when you attempt to overclock.[/quote]
yeah m2k3, no matter what i do it spazzes out anything above 2.7 i have it clocked just under 2.7 now everything else on auto and its stable, oh well at least its an extra .3 ghz
