Trying to get 3770k to 4.8GHz. Any advice?

post #1 of 7
Thread Starter 
I have my 3770k delidded and im using a H100 cooler. I ran prime95 blend overnight with my vcore at 1.44. 0 errors after 5hrs, I know thats not enough but I needed my computer lol. I was wondering is 4.8GHz worth 1.44vcore? Or should I try 4.7GHz to get lower vcore? Oh and by the way my max temp on prime95 was 88C with a very warm room. I live in south Texas lol. Its never cold here tongue.gif

That voltage is perfectly healthy, although i would run it with offset if you haven't done so already. Prime95 doesn't guarantee 100% stability, and the best way for that, IMO, is to just do whatever it is that you do with your computer, and regularly check for WHEA errors.

AFAIK, so far no one has managed to 'fry' their IB by overvolting it and reports of degradation are limited. The worst case scenario being that you would have to bumb the vcore up a notch in order to maintain the same overclock, if it indeed was degrading considerably faster than it is now at stock volts. This process would take months or years, depending on the chip and the voltage used. Essentially all chips are affected and any kind of over volting just speeds up the process.

FYI the max voltage Intel uses under thermally controlled conditions (think a massive waterblock with 3 loops running through it) is 1.6V. So as long as you stay under that and keep your temps in check then it shouldn't degrade the part too much.

I want my chip to last so I like to keep it under 1.35 and 80c I can get to 5ghz at 1.5 but like to run 24/7 at 1.280v @4.7ghz

That's not true at all. Intel has never specified a max. Where did you get this from (not being antagonistic, I actually am curious where did you get this from).

Max voltage, based on people's experiences, are around 1.5v-1.6v but unlike Sandy Bridge, I haven't heard anyone say anything has happened even in those voltages. Ivy is quite hardy.

What do you mean? Is there any indication that over even 1.5v and 90*C would hurt the chip or make it not last? I think we got a chip there that you're talking 15+ years lifespan, so degradation is more like 20 years to 18 years. I mean these are all imaginary numbers but I haven't heard anything of ivy degrading.

Hey. Recently I've tried to OC to 4.9 just for the heck of it. I'm using i7 2600k with Kuhler 620 water cool on Asus Maximus V Gene.

Like you I've gotten to 4.8 with manual with 1.4 Vcore around 2 days ago. But then I noticed that if I turn on Ai OC on and changed the multiplier to 48. I get 4.8 GHZ with temperatures similar to a auto 4.6 OC.

So I would suggest to try the Ai OC and change the multiplier.

Right now I'm rocking 4.8 GHZ, 1.2910-1.3661 dynamic Vcore, 29-34 idle and below 74 load, vol offset auto

I do suggest you stress test your cpu after OC to make sure it's stable all the way. GL.

.

I just know that around 1.6V is what they use to try to find walking wounded chips...ones that would die within a couple of years of normal usage. 1.6 obviously isn't the "max" because exceeding that is common on LN2 or LH...just that's the max Intel uses (coincidentally the max frequency Intel uses is 4.6 Ghz). That's also why I say that it's not just temperature that kills a part...voltage does too. I assume there's some MTBF computation performed, I just don't know what it is or who does it.
