3570k stability @ 4.8Ghz

post #1 of 10
Thread Starter 
I find it easy ocing my chip all the way to 4.6Ghz without manually setting anything else other than vcore, from that point henceforth it gets tricky. At first I would get a 0x000 and 0x03B bsod errors and increase the vcore, it would result in better stability but afterward I seem to get a bsod error 0x024 when adding more vcore and comes much faster than usual the more I add vcore, had better results with a VTT increase but still can't get it stable at 4.8Ghz. Vcore seems to have climaxed at 1.375v anything more and the system bsod faster. I almost feel as though I can use less than that vcore from the way its behaving especially with increased VTT. If I increase VTT any further it bsods much faster. LLC set to turbo anything lower than that .... bsod!

Board is GA-Z77X-D3H
Bios F16

Am planning on a NH-D14 as what am currently using can't really stand up to the task. What else am I supposed to be looking at? Any gigabyte takers here?

Thats not enough information.

What else is in your system?


We want everything from PSU to RAM.

PSU - PC Power and Cooling MK III 600w (seasonic build)
RAM - KHX1600C9D3/4GX (8GB) 2 sticks (Not overclocked)
No gpu yet

It's just come to mind, is it possible that power saving features can cause instability at this speed?

Im running 4.8 here for couple months solid. Running 1.4vcore have you changed vccsa/vtt or anything? I had to increase vccsa to 1.15v for stability however my ram is also 2400mhz. I disabled c3/c6 and left speedstep and c1e enabled so it can idle. Also I ddint touch vtt left it auto/stock 1.8 hope that helps some.

My ram isn't overclocked so I wouldn't need to change anything in that respect.
I changed vtt two notches up which lengthens the time before bsod. What is your pll voltage?
Your vtt voltage is very high mine at stock is 1.050v
Does bsod 0x024 mean vcore low or vtt low or vcore high or vtt high?
What is your cooler?
Mine has all power saving features enabled. What does c3/c6 do?

Try vcore load line calibration -> extreme
post #7 of 10
sorry meant pll 1.8 however like abover said load line calibration may be the cause I use ultra high. which is 75%

What does it really do to the chip? Does it degrade it overtime?

I remember a user here on the forums asking an Intel engineer what CPU PLL Volage does and remember him saying it can reduce the lifespan, but nothing to severe. And the only I think it could reduce it is if you kept upping the voltage. Mine was set automatically to 1.79v. I reduced mine down to about 1.75v, which is what you should try. It is really important when going for big overclocks to change the PLL voltage or else you get all those BSODs.

Most of the time PLL can be left to Auto or 1.8 Most have told me that anything over 1.8 can eventualy cause degration. Just leave it at Auto why mess with settings that are on Auto and work just fine. Esp Pll type tweaks.
