3570k Voltage Questions

post #1 of 11
Thread Starter 
My 3570k defaults to 1.165 Volts, I can manage to get 4.3 Ghz out of it at 1.180 Volts. If I try 4.4 Ghz at 1.200 Vcore IBT errors out on the second test using "Maximum." So I'm wondering if this is normal, if I should try adjusting the PLL or perhaps some other form of tweaking. This is on my Sig system.

3570k
Gigabyte GA-Z77X-UD5H
Corsair Vengeance LP 1600 Mhz CL9

You could easily add a few more volts, just stay under 1.3 and you will be more than fine. But I would think 1.22-1.25 should be enough to get that stable. Also, I'd make sure your LCC is at max to make up for what ever vdroop you have.

I have the LLC set properly, guess that extra 100 MHz is just going to require more power than I thought. Based on some other system issues I may be doing an RMA on this chip any way, just trying to rule out the motherboard. Been seeing a slew of seemingly unrelated BSOD's, even at stock speed and voltage.

It is much more likely your mobo is broken than your cpu. You may not have a great chip for overclocking, but intel has a very low rate of bad chips.

Thats why i dont think OCing to anything above 4.5 Ghz is worth it. The real perfomance gain vs voltage added and heat generated is just not worth it. I can run 4.2 Ghz / 1.1V for 4.4 Ghz / 1.2V abut for 4.5 Ghz i almost need 1.28V.

I know you are not complaining about your voltages, but to give some reference..

4.4 GHZ for my chip is 1.365v.
4.6 is over 1.45v.

So if you are upset about the stability OR the overclockability.. Remember, mine will always be worse than yours. biggrin.gif

Hoping to hear from Gigabyte by Tuesday. After all these Z77 horror stories about Asus I plan to film the entire removal and packaging process, last thing I need is for them to claim I bent the pins or didn't package the board properly.

overblown rumors....
I had an RMA with ASUS just earlier this month, entire process from me packing up board
and then sending back board to me was 11 business days..
made reference to it in the P8Z77 Owner's thread..

it's MSI RMA (mobo) which took almost 5 weeks that you need to avoid.

I've only ever owned Asus and Gigabyte motherboards, and this is the first issue I've had with any of them. Good to hear that the Asus complaints are overblown, my old P5N32-E SLI has been my favorite motherboard to date.

My point isnt whether the voltage i have to use for given OC is better or worse than someone elses but the jumps in voltage you see when trying to go for higher clocks. I mean at which point does it stop being worth it to OC more. If you have to add another .015V or more voltage to get just a 100 Mhz boost at which point your are probably at 1.4V or whatever and your temps start to get extremely high. Id say that for most people 4.5 Ghz is the sweet spot between performance gain and heat generated with voltage added.
