Q6600/G33 mobo won't hold overclock

[Rick540]

What's up haven't been on these forums or even keeping up with tech for quite some time. Anyway, my current PC is a somewhat aging Q6600, Gigabyte G33 mobo, Corsair XMS DDR 800 RAM. Stock the Q6600 runs at 2.4 GHz. Ever since I built this PC a couple years ago, I've run it overclocked to 3.0 GHz. Using a 2.50 divider, the RAM runs at 833. Recently though, the PC won't hold the overclock. Sometimes it will, sometimes after a restart it resets to the default 2.4. As time goes on, the overclock is sticking less and less.

Any guesses as to what it might be? My only idea is maybe the CPU is getting worn out from the overclock? At 3.0 it only runs at about 35 idle and maybe low 50's when gaming or whatnot. My second guess is the RAM, but it tested okay and it's only been running at 33 MHz over the stock clock. BTW, no voltages to either the CPU or RAM have been changed. Now that I mention that though, maybe if I try to bump up the voltage some on the CPU and see if the overclock sticks. If so, that's a sure sign that the CPU is getting tired right? Other than CPU or RAM, it could only be the mobo itself I suppose.

Thanks for any replies.

hmmmm, this is odd, see my other thread i just started.

What is your multiplier on yours?

Mine is maxed at 8, and now my Q6600 wont run at 2.4 even now. Im not sure how long it has been like this but maybe a while now.

It will revert to 2.13 if it doesnt post, and I never had it oc'ed all the time.

I have a gigabyte ud3p board.

My current, and previous, C2Q have both lost their overclocks over time. The Penryn QX9650 i have now was stable at 3.6Ghz for a couple of years and then BSODs started creeping in. Backed it down to 3.2Ghz with everything set to Auto in BIOS and it's stable again.

Could be the CPU or Mobo that's gotten tired but CBA to find out which. It'll be replaced next year anyway.

imma retard.

make sure your multy is on 9.

that was where i was fucked. it is 2.47ghz now..........

.....yes, im an asshole

Well, kids . . . I mean . . .folks . . . It's been a while.

I found this interesting since I'm still running an old Q6600 B3 on an nVidia 680i motherboard. I have a second system which I don't leave running 24/7: an nVidia 780i board with an E8600 OC'd to 4.15 Ghz. The Q6600 was OC'd to 3.0 Ghz -- running almost continuously except for a twice-weekly shutdown.

Take a look at the core voltage reported by CPU-Z. Also -- take note of your motherboard and whether or not it uses solid-state capacitors. About twice over four years, both of these systems began to evidence some instability, and I noticed that the VCores reported didn't match those earlier in the system's life-span.

You can keep edging up the VCORE, as I did. I chalked it all up to "capacitor aging."

And -- I could be wrong about the OP's problem. I can only speak for myself: At first, I kept the "set voltage" or the voltage chosen in BIOS below the Intel spec maximum that guarantees some longevity. More recently, I've edged up about one or two notches above that spec value, but the CPU-Z reported voltage is still around 1.30V for the Q6600 B3 C2Q.

If ya gonna over-clock, ya gotta expect a shorter lifespan. I suspect it is just motherboard aging, and I tweaked my OC. But your problem COULD be different.

I'm hoping to limp through 2011 with these . . . antique Kentsfield and Wolfdale builds, and go for an i7 2600K, P67 or Z68 motherboard, and a nominal 2x4GB memory kit to start. But not until certain "milestones" are reached in this .. . . comet-tail . . . . of the Bsh Economy. Cash for everything now . . . .

I didn't know that could happen. if your on a quad already , the big leap isnt sandy the big leap from your G33 rig would be 32nm Ivy Bridge

You wont see a different I promise you.
things already fast,, Core 2 was a milestone so to speak.

Indeed....I've seen it too....good post. I also begin to suspect an aging power supply when this start happening. On different systems I've fix the problem with either a new mobo or a new PS. If you're not running crazy high voltages or temperatures, the Core processors can take a mild OC for years. I ran an E6600 for many years at 3.2GHz under-volted. I did go through a mobo AND a power supply over that time....but the CPU keep chugging.

fun times with the good old q6600 i had the g0 outstanding chip popped that baby in a ecs g31 or g31 i forgot which it had options to overclock had it at 3.4ghzs for a short time,till the motherboard popped usb ports like cherries and the ps2 ports but popped it into a asus maximus,i loved that processor to death,that chip for me on that asus ran stock voltage at 3.2ghzs for me,maybe the g33 isnt that great for overclocking?

It very much depends on what you are doing. My Q6600 ran at 3.6Ghz, and the 2600K I now run at stock speeds are running circles around that Q6600. And I mostly do gaming, some video encoding, etc.
