i5 4670K + MSI G45 MOBO overclock Guidance - Page 2

post #11 of 19
Thread Starter 
Ok, reporting back. i turned on my computer and just doing normal web browsing the computer shut off and turned back on randomly not under load and no error messages. Before the Bios screen, it said Overclock settings have failed and default settings were enabled. I was not sure exactly what happened but i thought it may be due to lack of VCCIN so i increased it from 1.890 to 1.900. It now reads on HWinfo at 1.920, anyone care to give advice?

nobody? i keep getting the random reboot. i ran sfc /scannow with no problems. i checked for malware and viruses. I defragged, clean registry. I have been slowly upping the vcore voltage, i just brought it to 1.2 in bios. Its weird though i can play games and watch movies all day but when i turn it on in the morning it randomly shuts off while browsing the internet or something that doesnt put the cpu on much load. I know its not the PSU because before i OC it never did it before.

You need much more voltage to keep these chips stable I guess. Have you benchmarked it in prime95 custom blend for 8 hours or so? With all respect the MSI gd45 boards arnt great for OC really, they manage mild OC, but thats all.

i got another reboot event ID 41 and event id 6008. Ive read changing the power options to maximum fixes it but isnt it only a bandaid to the problem? Does C-State C7 have anything to do with this? im currently at 1.9 VCCIN and 1.256 Vcore(VID 1.229), Vring 1.15 (reading in bios at 1.2).

Hello mate.
I just bought same CPU and same MB , only teted for 2 days but so far i get :

CPU : 4400Mhz Fixed Vcore 1.262 Idle 33C / Load 83C with HyperEvo 212+ dual fan Tested on IBT (Intel Burn Test) Settings: Very High

CPU ring bus/Nortbridge Frequency : 4300Mhz Ring bus Vcore : 2.000

Corsair Vengence 1.650v 1600MHz at stock timings and speed (for now:D ) (VCCSA) voltage: 1.15 V to 1.25 V if you want to OC this

On Digital Power Bios TAB i set Powerphase to : Normal

c-States OFF

I hope i help at least a bit thumb.gif

hey thanks for the suggestion.

I reset settings back to stock bios config and it hasnt happened since. I've searched many hours trying to find the solution but nothing came up solid. 1.265 Vcore in bios was the highest i went to before i reset it back to stock. Why does this only happen when on light load (browsing internet,etc) ? ive been able to replicate the problem by turning off the computer and flipping the switch on the PSU, waiting 10 sec then turning it back on. It doesnt happen instantly but within 10 minutes of turning it on , it will reboot out of no where with no BSOD and give event id 41.

99.9% Off the times that it does BSOD on browser/java applications it as to do with memory error not vcore on CPU

It may be either the timings on your RAM or the MHz if you have OC them

Do 1 thing at a time :

Put Ring Bus ratio at stock
RAM speed at stock
RAM timings at stock

Go for overclock on the CPU core until you run instability , then up vcore by 0.05 at a time until stable, then up the multiplier again until its unstable. Mine cant reach 4.5MHZ multi 45 no matter if i run it at 1.20v , 1250v , 1.30v. So you have to find your limit until you reach 1.3v.

After that start up the Ring bus ratio by one and do the same method as the CPU for the voltage.

Then try reduce the Timings, 1 by 1 ex: 9-9-9-24-128-1T/1N

Reduce the 1st "9" to "8" , if fail put it back to 9, go to the next "9" and so on until you reduce all . Only 6 timings gives real performance ,
The others dont , they are
CL - tRCD -tRP -tRAS- tRFC- CR .......9 - 9 - 9 - 24 - 128 - 1T

I got 9-8-8-20-128-1T stock speed 1600Mhz because 1st: it doesnt give any performance boost from 1600Mhz to 2133Mhz in games2nd it cause system stability to decrease a lot so i leave it at stock.

Good luck thumb.gif

My ring bus has been set to stock (x34), ram speed has been tried on auto everything but also tried 1600 and 1333 ddr3, xmp off, 1.5 V 9-10-9-28-2(stock timing on package).


I have been able to run prime95 for 6 hours with 4.4 ghz and 1.2 vcore no problem. it is the times when i am not really doing much on the computer where it will randomly reboot without bsod and the only thing i can do by is eventmanager event it 41.
