I cant tell you that each cpu is different you need to stress test and lower voltages as low as possible while maintaining stability. Suggest using programs like LinX or Prime95. When you run these programs you better be watching the core temps of the cpu with either programs real temp or coretemp. You want to keep then at or below 80c.

Start of with a fixed voltage see what you need for 4.5ghz then set vcore to normal and then adjust DVID to till when cpu is full load the vcore matches what it was when set fixed. So lets say your cpu needs 1.25v for 4.5ghz when set to normal and vcore is to low like 1.20 you will have to set dvid to a + value untill you vcore reads 1.25v. Or the same goes if normal is higher then 1.25v like 1.300v set DVID to a - value untill load vcore = 1.25.

Adjust DVID is small increments as its not really a set figure you are adding or subtracting. If you need to raise vcore by 0.05v you may only need to move DVID by .002v. Also set LLC to Extreme, LLC is load line calibration.

If you get any BSOD error codes make sure you wright down the Stop error codes as this can help you determine what voltage may need to be adjusted.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

i changed to x45 on multiplier, vcore=normal (1.255) dvid=+0.000, LLC=auto, c1e=enable, ht=enable

on idle cpuid says 1.020v (x16) on load cpuid says 1.34v, but coretemp says 1.37, which one is the real?

so if i want decrease those 1.34 i have to set dvid=-?.??? to get something safe like 1.32 or 1.30 ?

thanks

Set your LLC manually to medium, high, extreme - whatever you think you need. I usually don't go above "high" for final setting, depending on how much droop I want/need. Reboot and see what you have then start adjusting DVID.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

can try dvid set to -0.0400v to bring cpu load voltage down from 1.34 to 1.3v if its unstable you can try -0.0200v for 1.32v cpu voltage

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Remember guys 3rd gen i7 utilize SVID where the VID will change as CPU multi will change. So what is normal voltage for 45x is not the same for 44x which you will also have to adjust dvid for. Dvid is also more of a percent then a fixed value so if he needs to drop vcore by .15v he may only need to adjust dvid by .05 or so. You have to play around with it to see. When I was playing with DVID I had LLC set to extreme. Maybe that was my problem and not using LLC High.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

right now is, x45 vcore=normal (1.255) dvid= -0,030, c1e=enable, ht=enable, LCC=auto
cpuid says on idle (0.98~1.02) on load 1.32 BUT------/ core temp says 1.37 (i dont know who i should trust)

i did rar test, with 4.2ghz vcore auto, dvid disable, everything auto, memory profile1 @ 1600mhz, the result was 4.166
now on this current overclock the result was 6.070



i didn't make a stress test yet but i will do later, but, what you guys think about 1.32v, it is good? safe?

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Ignore my last statement as I though you were using a 3rd gen I7, I see you are using the 2nd gen i7 2600k.

Wazza may want to speak about 1.32v ok for 4.5ghz with ht, It might be a little high as that was auto does tend to over volt, which can cause stability problem as well as low voltage.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

one last thing, the different reading voltage

cpuid (version 1.61)=1.32v
cpuid HWMonitor (version1.20)=1.32
coretemp (version1.0)=1.37
aida64(version 2.50)=1.37

who is the real one?

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Yes each software is gonna have its own discrepancies the only true way to know the voltage is with a digital multi meter(DMM) to read the voltage from the board. Usally Cpu-z will show you the must accurate voltage. I can tell you with my ud3h if you set LLC to turbo and a fixed voltage of 1.29v you will get 1.29v. Cpu-z may say it will drop to 1.28 or 1.27 but in fact it does not according to DMM and this was with a very expensive Fluke 88 DMM.

I would strongly advise not using auto voltage. I also strongly advise that you start with a base figure (stock settings) and play with voltages there and see how low you can adjust them while maintaining stability. Then move to say 3.5ghz, then 4.0ghz then 4.5ghz. At stock settings the value you see to the left of where you adjust vcore this is the cpu's VID for stock speed. So in theory you should be able to run stock speeds at this value either with vcore set to normal or with a fixed value. Most cpu's can actually run at a lower value but not all.

1.328v is fine for 4.5ghz,it just depends on each cpu,sometimes mine spikes to 1.344v in cpu-z

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

thanks for the tips, i will do some extress tests and if i dont get good temps, i will try reduce dvid

one dumb question:
what is the right cpu frequency to "marry" with the memory frequency?
like 1600mhz memory i will get good performance with ??? cpu frequency?

because winrar benchs raise 2.000 points from 4.2ghz to 4.5ghz with 1600mhz on memory

one last thing, the different reading voltage

cpuid (version 1.61)=1.32v
cpuid HWMonitor (version1.20)=1.32
coretemp (version1.0)=1.37
aida64(version 2.50)=1.37

who is the real one?

a correction: aida64 says 1.32 too and the gigabyte ET6 monitor say 1.32,
the real should be 1.32v

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

guys help me to manual overclock my system to 4.5ghz please...this is my system

i5 3570k 3.4ghz turbo boost 3.8ghz
gigabyte z77x ud5h
corsair vengeance 4gb 1600mhz
on board graphics only no video card
seagate baracuda 2tb 7200rpm 64mb
corsair gs 700 psu

thanks in advance

*please put screenies if possible hehe

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Just set LLC to turbo and set multi to 45x and set vcore 1.25v and test for stablity. Make sure to keep a close eye on your core temps, keep them under 85c.

You maybe able to use less vcore or you might need more vcore. You will have to test and see what you cpu likes. Screen shots can be found in first post of the thread.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

what about the BCLK 100.mhz i used the auto tuning lately my stability test gets up to 5.5ghz stock fan and air-conditioned room

[Acebmxer]

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

leave bclk to 100.03 unless you want to overclock the bclk. Please dont use the auto tune. All overclocking should be done manually in the bios. And I highly doubt the auto tune clocked the cpu up to 5.5ghz and the temps would be through the roof with stock fan. I have had 2 3770k cpus and the first was better then the one I have now, and with a custom water cooling the best mine could do was 4.8ghz with HT off and temps were around 80-85c.

Thse Ivy bridge cpus run hot you have to monitor core temps. I also have a 3770s cpu which is rated at 65w vs 75w on the 3770k. The 3770s with stock fan will thotal it self while under load from 3.9ghz to 3.7ghz as the cpu is over heating when running LinX. So there is no way a stock fan will keep a 3770k clocked to 5.5ghz unless you live in -100c temp.
