Athlon XPs overclocked so easily.  Every one of them that I laid my hands on was bumped up from its default of 1500-1800 MHz to a dizzying 2.2 GHz.  Before that, I had a few Spitfire Durons that were originally 600 MHz parts that I used a combination of the pencil trick and FSB changes to push to 933 to 1100 MHz.   Before that, I pushed a couple of P54C Pentium-75 CPUs from 75 MHz to  90-100 MHz.  Going way back, I had a 7.16 MHz Motorola 68000 in an Amiga 2000 that I clock doubled to 14.3 MHz before I bought a 68030 upgrade for it.  8)

I still have a 1700+ DLT3C sitting on my desk. I cut the traces and had it bumped to just over 2.5 GHz (from 1.47 stock) and ran the "wire mod" in the socket to bump up the vcore to make it stable.

I miss the old days. :lol:

My priors:
Pentium Overdrive (I know this doesn't really count) @ 120 MHz
Celeron 300 @ 450
Celeron 900 @ 1.2
Athlon 2100+ @ not much over stock, it sucked
Athlon 1700+ @ 2.5 GHz
Barton 2500+ Mobile @ 2.6 GHz
A slew of Athlon 64, X2, and Opterons (in desktop boards) that I don't remember. Delidded a few of them and ran them bare die.
Q6600 @ 3.6 Ghz (caused fire to come out of my old DFI board, DFI replaced it because they were AWESOME and claimed fault that the VRMs committed suicide)
Phenom II X3 720 @ 3.6 GHz (unlocked to 4 cores)
Bulldozer FX 8120 @ 4.9 GHz - for 2 weeks till I sent it back since it was slower than the Phenom II in many games...
i7 2600K @ 4.8 GHz
i7 2700K @ 4.6 GHz (the 2600K died, the replacement wasn't so hot)
i7 4770K @ 4.5 GHz (delidded, very casual and low OC)
i7 6700K @ stock...for now. Needs delidded, will throttle at stock with a full custom loop.

Holy thread necro batman! :lol:

Modern CPUs simply do not have the thermal headroom like they did back five years ago and earlier. You can get ~4.0Ghz without too much trouble but going beyond 4.5Ghz it starts becoming dicey. De-lidding IHS might buy you a little more headroom but exposed cores don't take too kindly to the physical stress of modern HSF/waterblocks.

I'm more than content with my aging 3570K which is able to handle 4.0Ghz at stock voltage since 2012. I suppose it could probably handle 4.4Ghz-4.5Ghz if I wanted to be more adventurous but it isn't really worth the headaches.

At this point, I might as well save up for a complete overhaul. It mostly due to DDR4, NVMe and USB 3.1 Type-C support though.

My highest OC is 4798 Mhz. My 4690k is only stable enough to get to CPU-Z on cold boots at that frequency. I keep it at 4.4 Ghz for everyday use.

Delidding and replacing the thermal paste is what I tend to do. It's easy, low risk, and gets you MUCH better temps. The wife's 4770K dropped 30+ degrees under load after replacing the compound with liquid ultra.

Unless it was a poor job at the factory (Likely story with that 4770K and other earlier 22nm parts). You probably get closer to a 10-15C drop with just replacing the paste and correcting the placement of IHS. You still void the manufacturer's warranty though.

Yup. My 6700K throttles at stock under a good waterblock and a big 360mm rad...it's especially poor.

That's insane, I thought hitting 93C~ on my 6700K in P95 @4.6ghz and 1.36~ vcore on my cheapy 212 evo was bad, I'm actually going to replace that cooler pretty soon, in well threaded games(and handbrake for that matter) I get around 70-75C which is fine except for the noise.
