List your most fun or favorite overclock

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).

Excellent point. However, there is a threshold of the amount of data a CPU can handle before it bottlenecks a GPU, which is how CPU/GPU bottlenecking happens.

Probably my best overclock would be off my old Athlon 64 x2 3800+ (Windsor chip). I was able to get her up from 2.0GHz to 2.81GHz.

I also had a decent overclock on my Phenom II x4 940. I could get her to run at 3.71GHz from 3.0GHz. Though, it required me to almost max the voltage (1.525V, max the board did was 1.55V) on my MB to hit that speed and it pushed the temps to the max thermal threshold on her.

My current i5-4670k I've got running at 4.4GHz.

Overclocking the Nexus 7 (2012)
I think it topped out at 1.7 GHz on the CPU cores, and GPU was running at 577 MHz. Wasn't the easiest overclock even though it's all done in software.

Of course, it is however VERY program dependant.
Here's one of the worst case scenarios you can get into :

GFLOPs numbers aren't affected by CPU speed even at this point.
I'm REALLY sorry about OT on this...

Nice! I'm assuming you had to root the phone, then install a custom rom with an OC kernel? Then use something like setCPU to configure your overclock from within the android OS?

You seem to know quite a bit about overclocking on Android. Wasn't a phone but a Asus made tablet for Google using the Nvidia Tegra 3.

Yep, (overclocking/rooting/installing custom ROMs) tablets is something I do in my spare time. I have a kindle fire HD with an aftermarket rom, as well as a customized and overclocked Motorola Xoom. Also have the Xoom II but the bootloader is locked from the factory, so no go on OCing there.

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.

I have an Ultra B as well with an Infinity plus a few Abits for good measure.
I'll go ahead and say a Socket A really doesn't need much more than 2.0v's to max out the chip, perhaps 2.1v's and that's it.
Any more and you're just cooking the chip.

@Susquehannock Check around for a good Abit NF7/NF7-S 2.0, Abit AN7 or even a Asus A7N8X Deluxe 2.0 or A7N8X-E, those are good clockers too and cheap enough. STAY AWAY from the LA versions of the A7N, total crap boards with a BIOS having 0 options for tweaking and also beware the Abit NF7-M, it's a crap board too.

You'll probrably have a harder time finding a good chip than a good board for Socket A nowadays, esp a good mobile but I can suggest an XP 2400 T-Bred since those tend to be good overall regardless.

An XP-3200 Barton is nice but be weary of overpaying, I guess it's up to you what getting one would be worth but personally I woudn't give over $20 for one. If you look around eventually one for a good price will pop up.
Most of what's on fleabay nowadays is just the leftovers meaning mostly crap chips.

Athlon 2500+ barton core @400fsb magically turned into a Athlon 3200+

Those were good CPU's to OC!

Decent but not the best I'm afraid.
The chip you named is a 166 chip and it's a "Defective" Barton core meaning it had trouble running at or much beyond 200 on the bus. It does have the 11X multi and while that's good those tend to be so-so compared to a true 200 FSB chip like a 3200.

You'd have to look at the very last character of the chip's name/model string since it's key, if it's a "C" (133FSB) or an "E" (200FSB) it's good, if it's a "D" (166FSB) it's not so good BUT there is always an exception to this tendency either way.

Mind you this pertains only to Barton cored chips, T-Breds, Palomino's and such are a different subject.

 

[lexluthermiester]

Ah, but the thread title doesn't say "Best" OC. It says "fun or favorite". For them, what they said is correct.

 

[Bones]

Wasn't referring to that but I get it.

If it's something you enjoy I guess it doesn't matter - I do know it does suck when you get something expecting it to be good and it bites instead meaning it's NO fun to OC.

With this at least you have an idea when looking for one ='ing the difference between fun vs frustration.

 

[NdMk2o1o]

Mine had no such trouble, I liked it because not only could you get it to run at 200fsb like the 3200+ but it was recognised as a 3200+ also, I'm sure lots of people were doing this back then, didn't hear much of any of them not being able to run 200mhz FSB though, I have an Athlon 1100 system for a retro build in a cupboard which I can't wait to tinker with.

 

[Urbklr]

Gotta be my E6550 C2D back when I was younger, so many good memories. Was on a P5Q-E running at 3.4GHz but I remember getting that board up to 500MHz FSB too. More recently I have had fun tweaking my Vega64, juggling power states and undervolting is pretty slick and allows a totally stable original boost clock(or higher) with much less heat and power consumption.

 

[Susquehannock]

Indeed. "best" is in eye of the beholder. To some Athlon XP 1700 and 1800 are better than 2500 Barton since they can OC as high at roughly half the cost. The Barton does have double the L2-cache, however. How much did that increase performance? I don''t know.

 

[TheoneandonlyMrK]

my most fun was Q6600 on a abit x38 quad GT, but so many platforms i liked to oc ,all Amd ones for a start.

 

[lexluthermiester]

It really depended on the program in question. Productivity software and web browsers benefited greatly. Games, less so.

 

[GoldenX]

Some games use a grid to determine if something on the distance should be rendered or not, so a low resolution helps get less draw calls.

I guess this. Highest bus speed and world record for a non overclockable e3-1290 xeon.

Not a huge OC, per se, but the platform is a difficult one to do a BLCK OC on, so that is none-the-less impressive!

My favourite OC was definitely a Phenom II 940 on a dfi 890fx lanparty board. My friend had just upgraded so we pushed it as far as we could, we got 3.8Ghz at 1.55V with 1 stick of ram and that tiny cooler after much fiddling(only 800mhz sticks), but couldnt get 4Ghz.

That reminds of the Phenom II 960T with possiblity of unlocking cores.

 

[Urbklr]

Reminds me of my PII 920! I think I got this result on a Freezer 64 cooler maybe?
