Absolutely. All it does is change the relationship between your set Vcore and your loaded/idle Vcore. 75% should put loaded Vcore pretty much where you've set Vcore in BIOS.

Did that and increased Vcore to 1.29 but got another BSOD with x45 after a couple of minutes.
Damn, temps never went over 75...
I guess that is that than

Yeah I'll try that tomorrow but I don't think it is worth the risk in the long run, no idea, I would love to have that 4.5 just for the OCD sake

Like you said, I upped the voltage to 1.32 and am running stable for a while now. But damn it feels a lot of Volts. Temps are ok 77-82, but ambient temps are a bit lower. What are the highest volts these things are rated?
Well, yeah but $50 less than a 3570k and I doubt I will notice any difference between 3.5 and 4.5ghz honestly.
Running 3.5ghz at .975 Vcore. Thats where I stopped lowering voltage I'm not really sure how much lower it would be stable but I'm pretty satisfied with that lol.
I'm a little disapointed, I'm not sure if it's my board or Ivy limitation but Sandy Bridge had more multipliers past the turbo multi and Ivy doesn't seem too. Like for example I had an I5 2300 and turbo multi was 31 but I was able to use 33 multiplier as a quad still (and 35 as single core). But with the 3450s, 35 is the turbo multi and it's also the max multi as a quad even though in the bios it allows me to put in 39 but still only boots with 35.
I might try some base clock overclocking and see what 3.6 and 3.7 takes voltage wise, but like I said I doubt I'll even notice a difference anyway. It runs 27c idle and 55c prime95 small FFT with a small 2 heat pipe 92mm cooler.
I see. I saw the bios wasn't updated to the newest so I tried that but didn't help.
Well, I'm stressing 3.7ghz as I write this....106x35 at 1.05v temps maxxing out around 57c. Crashed after 5 minutes at 1.02v so I bumped it a hair so I think it will be stable at 1.05v.

Just installed ivy 3770k gb ud5.
First try at 4.5 prime small ffts for an hr, 70c max temps, ambient 25C, vcore 1.188 load. No idea what vcore needed yet or whether stable beyond just over hr.
Anyone know approximate scaling on these to save some time, ie like i950 was + .035v for about every 100mhz past 4.2, then 4.6 scaling went to crap.
so far just adjusted vcore and LLC high.
going to try 4.7 then 5, just for fun.

From what I've been reading, 4.5-4.8 is when scaling goes out the window... You'll start needing bigger vcore bumps, and the temps will climb much higher.
Nice start there however. What is in your water loop?

They scale very well right to 5.5
and with th Gig board you should have no problem hitting 5.0 except the HEAT,I dont know what your cooling is but keep the heat down and easy to OC to 5.3 or so Great work and you have a chipper that looks like low volts. There are a few settings that helped me stay low on the gig boards I posted Screens of bios here.

I havent seen 5Ghz on air/water with a proper stability test yet so Im pretty sure the amount of chips that can achieve that is going is going to be very minimal. Scaling gets worse and worse every 100mhz you go past 4.7. I settled on 4.8 because even 4.9 was stupid voltage and temps. Every chip is different though so who knows. GL

Thanks for info guys, will save me some time.
cooling is 360 rad + 280 rad w/1600rpm push/pull, with 680gtx in loop (idle). ambient is 24.8 right now, water temp is 28.3C.
EDIT: not kidding about heat.
4500 2 hrs prime, 70C max temps, 1.188 vcore.
4700 20 mins prime, 80C max temps 1.28 vcore (1.26 bsod 1 second prime)

You need to post a notice on this thread... That way you'll get a bigger audience tuning in... I'll be there for sure.

T&B, I will check in on Ln2 as well. With these hot chips (higher mhz) ln2 is where most fun will be.
4.7 ghz probably be my 24/7, 5 ghz ok for benching on water, too hot, too high vcore for 24/7 or prime.
4.5 ghz 1.188vcore 2 hrs prime small ffts 70C max temps, ~10 mins prime blend 62C max.
4.7 ghz, 1.28vcore 20 mins prime small ffts 80C max temps, ~10 mins prime blend 71C max
5ghz 1.49 vcore prime crash after 2 mins
5 ghz, 1.51vcore prime small ffts crash after 6 mins, temps 103C
5ghz 1.52 vcore, prime small ffts, throttling down to 4.7, 1.50v, 105C.
5 ghz 1.52vcore, prime blend 1-2 mins 92C, too high vcore/temp for 24/7, though could lower vcore/temps with HT off.
4.7 ghz probably be my 24/7, 5 ghz ok for benching on water, too hot, too high vcore for 24/7 or prime.
4.5 ghz 1.188vcore 2 hrs prime small ffts 70C max temps, ~10 mins prime blend 62C max.
4.7 ghz, 1.28vcore 20 mins prime small ffts 80C max temps, ~10 mins prime blend 71C max
5ghz 1.49 vcore prime crash after 2 mins
5 ghz, 1.51vcore prime small ffts crash after 6 mins, temps 103C
5ghz 1.52 vcore, prime small ffts, throttling down to 4.7, 1.50v, 105C.
5 ghz 1.52vcore, prime blend 1-2 mins 92C, too high vcore/temp for 24/7, though could lower vcore/temps with HT off.

It has been years since I've messed around with Intel, but I'm having fun so far!
3770K at 4.5Ghz, Topping out at 1.2v
Cooler: Corsair H80 (High)
Case: CoolerMaster Storm Sniper
Ram: 16GB Patriot Division 2 Xtreme 1600 running at 1866 9-11-9-27-2T
Looks like I may have a stuck sensor on Core #0. It idles in the high 30's at every speed, voltage I have tried. I've re-seated the H80 a couple times as well.

Nice results, although I would not run my H80 on high.. that's very loud lol.
But during gaming the temps shouldn't get that high anyways.

LOL yea it is too loud. I normally run it on low, which increases temps by only around 3 degrees on average. For gaming, my temps are low 60s
