Will a 4770 boost my performance?

Yep 4770 non-K is your answer is not overclocking

And by meltdowns, I mean gradual system degradation over a period of time - down to the point where the CPU would not run at even 50% of original clock speeds.

what kind of overclocking were you doing there boss?

i've never had that happen to me where the cpu couldn't run stock after a few years of overclocking. I've had chips degrade and not able to hold the same overclock without extra voltage.

But not able to run half of the original clock?

That sounds more like damage due to excessive voltage when overclocking.

You just got a brand new Haswell Of course its amazingly powerful and fast!!!!!!!!!!!!!

This was way back in the day when the mobile athlons were king (before C2D).

I can't remember what clock speed it was, but it started something like a 40% oc? Had 2 exact computers (me and wifes).
I'm pretty sure I had all the settings right. Like I said, I used to have an account here (since 1999) with 5K posts... so I consulted the forums a lot. I would have been told I was "doing it wrong" by fellow AnandGeeks.

Mine, basically died. I lost everything as it corrupted the entire disk.
So I built a C2D machine (slightly overclocked it), they just came out at the time.

I immediately set my wifes to stock speed, but then it started blue screening... and the only thing that would make the thing run was to underclock it.

Kept doing that for months, until it was down to like 900mhz. That's when I tossed it in the yard and built her a C2D box too.

I had, years prior to this, suffered a couple of system crashes after a few years, which resulted in the entire disc corrupted (MFT trashed I recon).
So I figure it was probably due to the OC too? Who knows.

But hey, not saying I may not OC ever again... I mean, these new CPU's can do a 15% OC pretty easy, right?

A 4770k would hit 4GHz easily on a good air cooler, right? I don't have a problem with a 15% OC. No sir.

^ I still overclock but I understand where he's coming from. I've had more than 1 CPU slowly succumb to electro-migration over time. Keep in mind it usually takes years for this to happen, in my case it always happened around 2 years after use - but nonetheless it happened. I had a 300a oc'ed to 450 which did this and a couple of lynnfield systems - after a period of 1.5 to 2 years all of these system slowly became unstable at previously stable overclocks, and it wasn't due to temperatures or any other system component. I know this because a CPU replacement cured the problem in every instance. But like agent, I had to slowly back off of the overclocks, I had to run the celeron 450 at the stock 300mhz speed and it worked for a while. Then 6 months later it started becoming unstable at stock.

So no one should discount the dangers. They are there, although they usually take 2+ years to manifest. Heck, some may over-volt for 5+ years with no issues. Some may last 10+ years. It's all luck of the draw, but the main point here is that over-volting absolutely does cause electro migration, so with that said it makes sense to not go completely overboard with voltage - and if you do, be sure to use variable voltage which all newer CPUs support.

That being said, I still overclock, I just don't care. If a system dies in 2 years I generally want to replace it anyway - another thing to keep in mind is that the BIG culprit back in the day was the fact that you had to use manual voltage 24/7 in order to overclock. Newer SB/IVB and Haswell CPUs have improved low voltage idle states which can prevent electromigration (or minimize it) even when heavily over-volting a processor; you simply use the offset or adaptive voltage features.

The variable voltage of newer CPUs is a *huge* boon to overclockers. It does mitigate a lot of potential electromigration that may otherwise occur, so I feel that OC'ing and overvolting is a bit safer these days compared to prior years. But you must use offset or adaptive voltage to take advantage of it.

Thanks for that info Blackended. I wasn't aware of the variable voltage modern system employee. Good news certainly.
