Hey, I am attempting to overclock my i5-3570k to 4.5ghz

Build:
i5-3570k
Gigabyte z77x-ud3h
Asus Radeon HD 7850 DCII
TX 650 V2
8gb Corsair Vengeance

Current Results:

1. I'm having trouble stabilizing 4.4-4.5ghz, but I have to raise my Vcore up too much.
2. Can anyone explain why under load, voltages +~0.020v?

Thanks for your help!!!

welcome to the OC3D forums crator.

1a. how much do you have to raise the voltage up to get stable? what's too much?
2a. called VDROOP/Load Line Calibration if not enough voltage is allocated, it had to draw voltage to accelerate or stability is weak. how much did you increase the LLC?

have you watched/read the 1155 overclocking guide by TTL?
video or written
 
Yes that is the exact guide I followed.
1a. I found that 4.4ghz was stable around 1.29. However, 4.5ghz bsod after 2 minutes on prime blend at 1.35v.

1b. LLC is at extreme. However, I noted that the load voltage on CpuZ was the same no matter if LLC was on high, turbo or extreme. Only difference was the pre-stress test value.
 
1.29 to 1.35 for an extra 100mhz? That is quite a jump in volts and heat(i'm sure you noticed).It may have bsod to prevent voltage overload or it may have been your psu seeing that it needs to shut down to protect the cpu.

Looking at your graph I can say you are not giving enough volts to the cpu which is why in every OC you see the system giving it more than what you told it too: which is Vdroop/LLC doing that. I would suggest starting at 3.8-4.0ghz and find the most stable OC. Run OCCT for 8hrs starting just before you go to sleep to make sure it does not BSOD in the first few mins. After about 20mins go by and it seems the volts you entered are on display then let it run for 8hrs.

If it Bsods then you know overnight then you know it's not stable and redo the process again by upping the volts .05-.1 depending on what you think is nessecary. Hopefully this helps:)
 
Alright I will try that tomorrow. However, at 4.5ghz, 1.35v is not enough. Does that mean that my specific cpu is one of the sucky ones? haha
 
Ivy is very picky on volts. Hence why once you hit a certain volt threshold: the temps skyrocket. Happens on air/water cooling. Only time it won't is when your doing sub-zero cooling. With that big of an increase in volts i would say you may have gotten a lesser cpu. I would stick with the 4.4ghz for three reasons, 1) extend the life of the cpu. 2) keep temps down. 3) anything over 4.4ghz for gaming will show much less imporvement in the Fps.
 
Thanks for all this help. I'll test the overclocks for longer durations. It seems that purchasing cpu's is like that of a lottery sigh :/
 
glad to see you have started with the guide..

what was your stable stock multi, low voltage obtained voltage?
i see 1.02v and that was 30min stable with wait states off and turbo disabled?

could be a number of things, but I wouldn't lotto sucky, yet. different mobo and
phase control reacts differently on CPU management. any temperatures for the above
graphic?
 
all the values as seen on the table above were recorded after a 30min stress test using occt linpack. The temperatures varied from 55 to 65 degrees Celsius (from 3.8-4.3ghz).

The stable stock voltage after 30min was ~1.05. All power saving methods were disabled, also interal pll was disabled. I used turbo and manually set 38 for each.

Cpu pll was set at 1.650v.

I can only advise on so much, i don't know any of the terminology that gigabyte boards have. I can say though turn off C-state. I cant remember what it does but i think it is a power saving feature.
 
According to CpuZ around 1.03v , 3.8ghz it is around 55degrees average from all four cores. I don't have an ambient temperature reading at this very moment though.

Also I would like to say that this forum has been the most helpful from all the other ones I've attempted to ask for help on. so thank you :P

Room temperature is approximately 25.8C
 
What cooling are you using?

Anytime! That's what we are here for:)

Find a stable OC at 3.8ghz. 8hr tests etc. Then you should go on from that "checkpoint" you could call it.
 
I'm using hyper 212+ w/ noctua nf-f12. But im currently using the stock fan on full for testing purposes. I noticed that whatever voltage value I set, it will still jump ~0.020v.

So my approach is:
To test with occt for around 30 minutes to an hour. If the voltage does not drop to what I set it to, then I'll raise it up again. Q: Should LLC be set at its highest setting?
 
Why use stock fan? Mine as well use the noctua. LLC should be set to about 50%, Vdroop should be enabled as well. At least that's what i would start with, I am not a pro OC'er so take my words with a grain of salt.
 
I would only raise the voltage to keep stability. don't worry about the .02v swing.
that's kinda like a power valve in a carburetor (what is a carburetor?) and increases/
deceases with load to cover up an lean weakness. set LLC on extreme for now till
work on lowest voltage on highest multi with safe temps is stable. then walk the
LLC backwards.
 
Tested 4.4ghz @ 1.3v stable. Is there anyway to lower the vcore because it seems way too high for 4.4ghz
