hey all
so i have Gigabyte x79 ud3 mobo , i've tryied to OC my 3930K to only 4GHZ
what i did was using turbo boost multipliers up to 4 ghz for 1-2 cores , 3.9 for 3-4 cores and 3.8 for 5-6 cores , and everything else was set on auto (Vcore was 1.240 on auto) and pc worked well , then after i turned it off , went to work and when i tried to turn on , it wouldnt post or even do post beeps , i cleared cmos and it worked to defaults , then when i tried to oc it with Easy tune 6 to the Least option (4.08) it did same thing and i had to clear cmos again , so what should i do to reach 4GHZ without losing it like it does? i'm completely beginner so please go easy with me cuz i couldn't understand much of what i saw in other OC posts , thanks a lot
 
To be straight, the UD3 was probably the worst overclocking motherboard on X79. The VRM's would get way too hot so I would make sure you have some kind of fan blowing on the VRM area above the CPU. If it's not stable at even 4Ghz then you are going to bump the voltage slightly. I would not go higher than 1.3V on that board and make sure your CPU Heatsink is a decent one and up to the job.

well , my temp with turbo boost (3.8 single to 3.5 with all cores on) goes to 54c max on load with Furmark CPU Burner , i think i got a good temp there .. so it's Voltage that i should up a bit right?
 
i made a CPU Test by intel tool to make sure everything goes fine , u can see the max temp there as well

Yes, you can't ruin anything at 1.3v. Normally up to 1.35v is pretty safe but in your case I wouldn't go that high.

one more question , i should rise all of the cores situation to 4 GHZ? like 1 core at 4 , 2 cores at 4 , 3 cores at 4 ... etc , or what? sorry for the too many questions :"
 
Just raise them all to 4Ghz, so use the ALL CORE option. There's no point in staggering them at different Vcores as 4Ghz is really not that high. Most 3930's I had could do ~4.2Ghz on stock volts.

so i did what u said , raise Voltage to 1.3 and made the cores to 4.1 , pc is working well , Intel tool detected no errors , Geekbench got 2k extra score (fro, 15.5k to 17.5k) and temp maxes at 61c now , so how to make sure there is no mistakes in stability?

Use it normally.:D I sometimes run RealBench stress test but normally just game and maybe encode in the background while I'm gaming.

Just use it. Normal use seems to expose bad overclocks far better than any stress test. I was trying to dial in a 4.8GHz overclock on my 3970X recently and got it to the point that it passed hours of RealBench. Great! Except then I booted up Assassin's Creed: Origins and got a BSOD within two minutes.

You can be 99.9% sure that you're stable at 4.1GHz running 1.3V though. You should be able to do 4.3 or 4.4 at that voltage, and you might as well if you're setting the voltage there anyway. Just back it down again one notch once you find instability.

i see , so far it's working well :D

well , i'm more worried about the mobo , that's why i don't OC too much , Gigabyte's x79 has a great history with failures as i saw on many forums , and if it failed i can't buy another x79 platform easily as it's very hard to get , and it's expensive , so i don't wanna go high , 4.1 seems good enough for me :")
 
well, it happened again, when pc was working everything was fine then when i turned it off and tried to re turn it on it never post or does post beeps, just black screen had to clear cmos again .. idk where the problem is v core was on 1.3v and i heard that its more than enough for 4ghz :(

Sadly some Gigabyte bios'es where complete **** in this era and I was having the exact same cold boot issues as you with a 2500k system.

You set an overclock and do some stress testing and all is fine, every now and again on restart/power on whenever it felt like it you get the black screen and you had to clear cmos to get the system to boot which is annoying as **** to pull the case out, open the side panel to clear the bios as sometimes I even had to pop the battery out that was partially obscured by my graphics card so had to take that out.

Searching Gigabyte cold boot issues on google gives loads of results and sadly with my model of motherboard it can't be fixed unless they swap out the motherboard which some people where lucky to get replacements that fixed the problem for them as Gigabyte refused to exchange mine even though mine was still in warrenty. Gigabyte did'nt see that a system that would cold boot even with a 300-500mhz overclock a issue and pretty much ignored all the other issues people where having I pointed them to. :rolleyes:

In the end a b-grade Asus Z68 board was for sale on here for a great price so I purchased it and had no problems using the exact same system parts and was able to push my 2500k much higher at the same voltage.

well, sadly i can't exchange this mobo now as its been ages already and i bought it second hand , so i can never oc it you say, guess im sticking with stock turbo then, but now im even worried that the mobo would fail sometime even with that im very damn worried as i dont have money to replace the mobo if something gone wrong, will it be safe if i left it on its stock auto then? :(

That's fair enough, but raising the multiplier won't actually harm anything or shorten its lifespan. Voltage is pretty much all that matters in that respect, so if you're already using a set voltage, bumping up the multiplier as much as you can won't really put any additional strain on anything. Pity about the cold boot issue though. I've heard bad things about Gigabyte's X79 boards in the past and it seems you're experiencing that. Using 1.3V for 4.1GHz is already overkill, so that's not going to be the issue. You could try bumping up VCCSA voltage a little bit and see if that helps. Going all the way up to 1.2V is perfectly safe (higher than that even on C1 stepping chips), but there's no need for it. Setting it at 1.05-1.1V should be more than enough for your purposes. Whether or not it will actually solve your issue or not is another matter.

umm .. excuse my ignorance but im new to this and i didnt understand you clearly, if you can help me with more detailed steps of what should i do
 
and one more question, i fear that the mobo is weak and i want to remain safe , it always post on the stock turbo boost , if i left it that way it will be good and no probs will happen? or having this issue means my mobo is dying? cuz now im very worried...
