On CPU, a Phenom II X4 980BE, that was a Deneb one. Managed 4.6GHz all cores stable with a 212+, 4.7 on a single core for a CPU-Z screenshot.

On GPU, a 7600GT, voltmodded with a pencil to hell and back. It was my daily card when DX10 was the norm.

If I can get better cooling, I want to give this 1200 a go.

Wow those clocks are pretty incredible for a Phenom II, well done! Wish I had forked over the $$$ for a 980BE when they hit the scene... now they are few and far between.

My favorite OC chip was a CABGE Opteron 144 Venus for my 939 Biostar NF4-SLI-A9 board. The Opteron 144 were known to be good overclockers but the CABGE was supposed to be the worst stepping. I took it from 1.8GHz stock to 2.8 GHz before the motherboard ran out of clock and multiplier (IIRC?) options. When I bought it off eBay, the seller claimed it was a good overclocker. They were right. I remember wishing I had the ability to modify the bios for more clock speed.

Probably you ran it with auto voltage..? Which is bad since most motherboards give pretty damn much voltage on auto mode.
It was on and Asus Sabretooth 990FX. You may be right but I still enjoyed the heck out of it. BTW the CPU still works fine at 4.4 GHZ. I gave the PC to my nephew

I had a CABNE 0540* which clocked only at ~2.5GHz IIRC. It was interesting since I had a 3000+ Venice before which ran at 2.7GHz with stock cooler 24/7.

* IIRC it was one of the worst also.

Another favorite was overclocking with the Abit KR7A board. The 'CX' bios worked best for me. Don't have benchmark shots anymore since I made mistake of storing them on optical media. Whole other subject. But here's a shot from another forum back in 2003. Also Tbred B 1700 - running at 190x12.5=2375mhz. (stock speeds were 133x11=1463mhz). That early board could handle the FSB. My later revision KR7A would not clock near that high.

Funny to see my comment about looking at nForce2 boards. Must have been right before buying the Soltek. Obviously much better since the AGP bus was isolated. In that regard overclocking with the older KT266A boards required a stout AGP card to handle the extra bandwidth. Believe I was using a ASUS V7700 GF2 card in that KR7A at the time.

The easiest would be my current i7 6700K. Was it fun? Not really. I managed to push it to 4,9 GHz @ 1,415 V on air. It was stable enough to run CPU-Z and to play FC4 for some 20 minutes. No overheating and temperatures were below 80 °C. Cinnebench? Froze and them BSOD the system within 5-10 seconds. I didn't even try Prime 95.
Then I went to 4,8 GHz @ 1,385 V. Exactly the same thing. Adjusting the voltage to 1,4 V did the job, but Prime 95 crashed within 20 minutes. I played with FSB adjusting it to 105 and to 102,5 while manually adjusting RAM. Either way, I wasn't able to push to 4,7 GHz or beyond and have a stable system without surpassing 1,35 V. So, no fun.

Prior to i7 6700K I never had an "overclockable" CPU, so had overclock via FSB. I never pushed them too much. The biggest OC on such CPU was with AMD Phenom X6 1055T which was running @ 3,15 GHz... I think... :D

The funniest was overclocking Mediatek SOC on one of my previous smartphones. It took me a while to do it, but eventually managed it. I also changed the governor. Battery life was noticeably shorter, so I reverted back to stock settings.

Intel i7-3770K Ivy Bridge... from simple reason.
I had great CPU sample... forever I will remember that budget stop me to reach 5.0GHz stable 24/7.
I wish that so badly in days when people cursed i7-3770K because not OC as Sandy Bridge and compare i7-3770K with i5-2500K.
That's was not fair comparison and later everybody knew that Ivy i7 is only 5-10% lower OC average than i7- SB but tolerate far great temperatures and work nice on 85C.

I couldn't more than 4.8 GHz with AIO Prime95 stable 24h.
In that time AIO temps were similar to Noctua Tower coolers, and custom loop would give me 5.0GHz.
That would be shock for people, because I had him second week after launch date to see 5.0GHz stable Ivy, but....H100 couldn't better. :)

I didn't had doubt in any moment that Ivy Bridge as CPU and platform was better product than Sandy Bridge because other advantages.
That would be spread like fire... Some samples of Ivy i7-3770K are full stable on 5.0GHz!!! No shit, who can OC i7-2700K on 5.0GHz stable? i5-2500K can...We talk about i7 not i5,...etc... etc...

For me it was the nForce2/unlocked Tbred B era when, with a good board, you could easily OC by a Ghz, or roughly 70% on air cooling. A 1700+ running at 3200+ speeds. $60 chip running same as $300 one. Many sources list them as one of the all time best overclockers.

Here are a couple screen shots from back in the day. Soltek Sl-75FRN2 board. 1700 DLT3C 0310 WPMW. So many to choose from. 1700 0307 VPMW was also popular. The 1800 overclocked well too. Did so many of these. Surprised I never toasted any. All still alive and kicking. Really need to move my nForce2 retro build off the back burner.

Nice! While I prefer a minimum of 120fps, 30FPS is acceptably playable. I personally would go down to 1080p to get higher framerates. GTA5 looks good at 2160p, it just isn't optimized for it.

Early conroe were great fun, I think the e4300 is a close second behind the q9550 for me.

Intel left so much meat on the bone so they could sell cheap heatsinks back then xD

Hmm great, yeah my 2500 XP-M I wasnt sure how much more the vcore needed to be to run above 2.2GHz
Oops! My bad. Please disregard my last responce. You were asking about the nForce2 system. That was vCore 1.8. Max the Soltek BIOS would allow. Wondered how high the system would go if the settings went much higher, like the DFI Lan Party.

Those mobile Barton are/were great. Never did have one personally. Considered buying one on eBay a little while back but all the good overclockers are surely gone at this point.

I got one because I crushed a perfectly good Barton 400 (200) that was a sad day indeed.

Yeah I have a UltraB still, will revisit overclocking now that I have knowledge and confidence of keeping it nice and frosty.

Hope to drop 7 on it with modded NF2 AGP GART

UltraB. I am envious. Always wanted one but the package was too rich for my blood at the time. Opted for the Soltek FRN2 instead. No regrets. Very stable boards. Still have a virgin one that I haven't even removed the stickers from. Final revision too. After they switched to the Japenese non-plague ridden caps.

Since GPU isn't pegged at 99% usage most of the time - lowering resolution won't help with FPS.

That's not completely true. Wile the GPU does a lot of the work, the CPU still has to supply the GPU with data to process. Lowering the resolution will reduce the amount of data the CPU has to process and thus lower the amount of bottlenecking that it is causing the GPU. Lower the res to 1080P and see what it does to framerates.

@lexluthermiester Pixels are created by GPU, on GPU, for GPU.
CPU doesn't have to send more data for higher resolution, because data send by it to GPU is vector based (ie. it doesn't have a "resolution in pixels").
In more general terms : It's just a bunch of points floating in 3D space that have various data attached to them (XYZ position, lighting, texture, etc.).

The CPU still has to do work before the GPU renders a frame, otherwise CPU's would never(or rarely) bottleneck a GPU.

That is true, however that part is independent (mostly) from rendering itself.
In short :
If you throw enough pixels/AA at GPU - you will always end up GPU b'necked, regardless of what CPU you are using.
Which is what you see when a ~3,6GHz Q6600-type CPU can almost maxed out GPU usage on GTX 1080 when playing GTA V (in some specific places).
