I have a Core2Duo E8400, stock 3.0ghz overclocked to 3.6ghz with a Xigmatech s1283 cpu cooler.

I overclock because like it says I want to squeeze as much performance as I can from my hardware.

I've been overclocking my CPU's since the Pentium 1 days.

Yep, Trusty Windsor X2 5600 @ 3.1 Ghz ....been that way for as long as i can remember..... A little weak these days... but I still see no reason to shell out tons of cash for an elite rig anytime soon. Using a Zalman 9700 heatsink and 3 120mm fans in a relatively spacious case...

I overclock to find out how far I can push the system and run benchmarks. Then I usually back off to find a good balance between a moderate overclock and low temperatures.

An aftermarket heatsink/fan is a must. I tend to use hardware website reviews along with Newegg customer reviews in my decision regarding which HSF to purchase.

CPU: Q6700
Cooler: Tuniq Tower 120
Motherboard: Asus P5E

Maximum Overclock: 3.67GHz
Normal Overclock: 3.0GHz
Temps (normal OC) - Idle: Mid to Upper 30's Celcius | Load: Mid 40's Celcius

I don't overclock. I'm nervous about doing something wrong and causing instability or shortening the life of my components. It also doesn't really interest me.

I have a Q9450, oc'ed to 3.2GHz. It was a quick and easy mod. That is the bottom line for me. I want to get more for my money, but I'd rather play ON my PC than play WITH it, so every last MHz doesn't matter to me. That overclock is not very stressful for that chip (no voltage increase), so the cooler is just an AC Freezer 7 Pro.
I also have a 4850e on a 790GX that is not overclocked, and won't be; it's on 24/7 and I want lowest power consumption.
My wife's PC is a 5400 X2 on a 790GX. It has a Ninja Mini on it, but isn't overclocked. I just got some better RAM for it, and will likely try to push it some (she runs LOTS of stuff at the same time), but I think I see a 720 in her future.

I have a Pentium Dual-core e2160 @ 3ghz, stock 1.8. I overclock because I see a huge increase in performance versus stock. I use air. I have a Cooler Master Hyper TX2 CPU cooler and three fans blowing to create airflow.

I have never been a big fan of overclocking, the expense of a new system compared to the performance gains is not worth the risk in my opinion. Not only running the chance to burn out your system but also lowering the life time expectancy of components. I know that today's processors have gotten better at protecting themselves, but I still don't see the benefit of gaining another 5-6% performance when everything runs as well as I would expect at default settings. Then again I upgrade at least once a year.

e4400 from 2.0 ghz now to 3.0 without a problem, 300 mhz fsb with a 10x multiplier. using an arctic cooler 7 pro which keeps me at about 30c most of the time. I also overclock my ram and my video card.

Phenom 940 with an easy 3.5ghz overclock. Again, squeeze more performance without sending my hardware into a panic attack.

Cooling with a ARCTIC COOLING Freezer 64 Pro. Again, nothing crazy. Does the job very well and quiet at the same time.

Amd PII 940 3.5ghz
MSI K9N2 SLI Platinum
BFG GeForce GTX 285 OC
Corsair 4gb (2x2gb)

I have an AMD X3 8650 @ 3.1 Ghz 1.3V and I am using Sunbeam Core Contact Freezer and Jetway HA07 motherboard with it.. Can't push more stuck with value ram. . Will possibly get Corsair Dominator DDR2 1066 soon..

Here is the specs

AMD Phenom X3 8650 @ 3.1 ghz
Jetway HA07 790GX Board
Transcend P-Series DDR2 800 Mhz [5-5-5]
Western Digital 640Gb AAKS
Sunbeam Core Contact Freezer
Thermaltake M9 with 2 pre-installed fans.. will change them with Antec Tri-Cool 120mm and add an extra 120mm .
POV Black Diamond 500 W SMPS

Never overclocked a computer - damn Dell laptop. I really hope to build a PC sometime this year and maybe test out some slight overclocking with an i7 or Phenom II.

I sure do. I have an older Athlon X2 6000+ and although I can't get much out of it I can get to run at 3.272 very stabley for 24/7 opertaions on watercooling and it helps out a lot.

I also have the new AMD Phenom II 720 (which I'm currently overclocking for the AMD virtual contest) that I will keep overclocked on just plain air cooling using Thermalright Ultra 120 Black Edition.

I find that's it definitely a way to get more bang for the buck. Even though it might make it last a little less time with the the way chips get outdate so fast, there's really no problem with keeping overclocked with the right cooling.

With my watercooling setup it stays at 39C at 100% full load running SMP Folding@Home.

I have an E8500 3.16 stock at 4ghz with Artic Frezzer 7 pro

Overclocking is a sure fire way of gaining extra performance for free, carefully selected components increase the percentage overclock you will get within a budget you have pre-defined.

I have overclocked since P2 days and have never had a really bad experience or lost major hardware except a few athlons along the way(My bad, super stressed the components knowing I was on track to killing them)

Have had some superb OC before, Best though are P4 3.0ghz at 3.8ghz prescott chip on s478 with zalman flower cooler, still running daily at this clock after several years and my current core2duo 7200 clocked at 3.8ghz with artic cooler freezer 7 pro which has been running flat out for ten months now at this speed, even had it over 4.2ghz before booting into windows.

Point is, if you have the correct kit, take your time and do it slowly unless you know what the kit is capable of, you can gain way more than 3-5 frames per second in my view.

Used to OC in the old days. Now I run AMDs and use CnQ as I think it works great, uses less power and keeps everything cooler. I just don't think there is enough performance to be gained (if you're not playing games, that is) to justify to risk or petentially shortening the life of your components.

I have a Core 2 Duo E4300 running at 3.2 GHz, 400MHz FSB. with P5K. (which sux)
It's cooled with an Arctic Cooling Freezer 7 Pro.
It runs ok, doesn't overheat, but runs hot!
NB: 1.40V, RAM: DDR2 800 "cheap" Apacer memory, tightened to 4-4-4-12 and overvolted to 2.15V.
What others are missing is the gfx card.
My 8600GT runs at 652MHz, 1400 MHz shaders. GDDR3 runs at 1.9Ghz, (950MHz).

I have an E7300 at a safe overclock of 3.4Ghz with no voltage increase. A little extra boost with minimal change. everything else is at default. =)

I no longer overclock - did back in the glory days of AMD. Now that I have a nice employee's discount, and prices in hardware have come down, I now only overclock "lite" - adjusting clock speeds via Riva Tuner, and not playing around with voltages. Like some have mentioned here, I but just past the bleeding edge now, and wouldn't like to have to accidentally have burnt out a component too quickly.

It doesn't help that I haven't bought a 3rd party mobo in a while. But when you get them for free....

Intel dg33tl
Intel q9650
Crucial 4x2GB 800MHz
9800 GX2 (the only OC, to 700/1050/1700 - core/mem/shaders)

I do overclock where it makes sence for daily use. So, yes, my C2D E4400 is clocked to 320x10 (3.2 GHz).. Air cooled ofcourse, with Scythe Ninja. Sometimes I do get "burned", no in failed hardware (yet ), but for example this same CPU worked fine on this same frequency even on box cooler.. so this was money wasted on aftermarket cooler. Also, I don't overclock RAM, as it makes almost no sence for stuff that I do. My GPU was also overclocked, both when I had X1950, and when I bought HD4870. Now I'm back on X1950, but haven't overclocked again, because it won't give me much advantage in current games anyway.. but when new card arrives - it will get clocked again.

I never did go to water cooling though, but only because prices of such setups make them less bung for $$$ than using air cooling. Pretty much the same as my Ninja "miss" - I doubt that this CPU would get much further even if it was watercooled.

What I DO NOT overclock are PCs used for just surfing on the Net and using office apps.. makes no sence to do it there, as any CPU is already overkill for those apps.

Cheers!

(I'm starting to like these QOTD articles keep them comming! )

My current computer is an old Dell with a Pentium 4 1.8GHz, so I'd certainly like to overclock it, but the motherboard doesn't allow that. My computer at my parents' house, though, has a Pentium 4 3.06GHz oc'd to 3.22. Not astounding, but it showed some improvements.

I used to do more hard core overclocking with volt modding full blown water cooled setups, but grew tired of always having to modify everything when I got new hardware which was often. So I have moved on to just using upper tier air cooling and well ventilted cases with quieter fans. Been running Intel C2D e8400 at 4.2ghz for a long time now and there is no denying that that is a good performance boost over the stock 3ghz. I am less concerned about memory overclocking as the gain is generally less than 2-5% even with extreme memory overclocks. I also overclock my video cards, but no longer volt mod them. Currently have a GTX260 core 216 doing 715/1480/2360 which honestly a lot faster than stock and does make a difference in some games.

I've got an Athlon 64 X2 5200+ topped out @ a measly 3.016
HT Link is x4
Vcore is 1.4
Cooled w/ a Thermaltake MaxOrb
Its max temperature is 52 degrees C when running Orthos

overclock every rig i have. Want to get as much power out as i can get without burning up my CPU's.

Qx9650 @ 3.6ghz w/ OC profiles up to 4ghz (3 evga GTX 285 FTW stock cooling) CPU water cooled with zalman passive sink

phenom II 940 @ 3.4 w/ up to 3.6ghz (3870x2 + 3870 stock)
Cpu water cooled with passive sink

Q9300 @3ghz (3870x2 + 3870)
water cooled w/ fan sink

E7200 / G31. Dont need OC. Better save energy. Therefore passive cooling and no noise. Fast enough for web, office-purposes and medium games.

Why overclock - I can't see the differnce - maybe it works for games high end - but I wonder if it matters.

I have Gigabyte X48-DQ6 and run my Q9550 @ 3.4ghz(400*8.5) using a Xigmatek HDT-S1283 heatsink.

Its a moderate OC, that i can run 24/7... i don't see the need of pushing it to 3.6-3.8

I have a E2140 overclocked to 2728MHz.. (about 70% overclock..)

The processor is running with stock fan and no overvoltage. It has been run at 3120MHz (95% overclock) with a moderate overvoltage, so these 2.7GHz should be fine for it. (It average temperature is 30-40C.. )

Its not worth the hassle. i found building your own power house computer is worth the value. their is a big difference between dual core and quad.
clock speed was never our issue more like cpu processing power.
you could have a 4.0 MHz single core computer but a 3.0 MHz dual core will out perform it any day.

For about a year I have:
Q6600 G0@3.8Ghz 400x9 VID 1.48V cooled with Aquagate Max 34CIdle/59CLoad
Gygabite p35DS3L v2.0 (no problems there after adding a small fan onto the NB heatsink)
Corsair XMS2 800Mhz 4-4-4-9 1:1 ratio
MSI(216)Geforce GTX 260OC 735/2350 stock cooling fan 80% gaming only
GFXcard OC has not produced as much improvement in gaming as CPU OC thus I don't run it often.
Upgrading to i7 is not worth to me, since gaming performance does not increase substantially in the games I play @1680x1050.
I guess I'll have to wait till 32nm chips come out.

I do lots of HD video editing and hi res photo editing, so overclocking was worth it for me. Of course I pushed by Q6700 to the max on air, which was 4.0GHz for Vista and app stable, but only 3.98 for running benches. I also overclocked the RAM and the video card up the wazoo to find the best possible performance my system could put out without starting on fire. (the voltage it took to hit 4.0GHz is kinda scary - don't recommend!) After benching I dropped it to 3.67GHz on the CPU for 24/7 operation. The performance gain for the extra $60 I spent on the TRUE was extremely well worth it. And I had all this great performance on the budget friendly $120 P5Q Pro. Stability was never compromised, and the processor is still kicking today, notwithstanding all the abuse I've given it. I've seen real, tangible, noticeable gains in heavy duty games and apps. Some programs will never benefit, but a lot of them do, and multitasking and boot speeds benefit from the higher clock speeds. A full GHz overclock for an extra 60 bux is a bargain.
