I have tried to OC to 4.0 which was my goal but i couldnt understand a bit from every guide i have seen.

I went in bios , set 20 multiplier and 200 base to get 4.0 increased Vcore 1.3 or a number very near that and my pc couldnt even start.

I have turned everything back to default and clicked the OC thing on the Mobo which upgraded from 2.8 to 3.4.

MSI is having control center thing as windows app which on it aswell i have raised the base to 222 and the previous auto OC from msi gave me 18 multiplier and i have reached 4.0

so the results were :

Base : 222
Multiplier : 18
Vcore 1.3
Ddram was increased aswell to 1.7

I ran prime for 10 minutes there wasnt any error and temperatures were tops 79c.

I am really not sure if OC-ing system like this is good or i need to do changes and that is why i am here and asking anyone who can actually help me.

My speccs :

PSU = Gembird 600W real power
Mobo = MSI P55
CPU = i5 760 2.8
RAM = Muskin 2x2gb dual channel 1600mhz
CPU cooler = Coolermaster Hyper TX3

Forgot to add , in my case i am using 2 more coolers 1 at front 1 at back of the case , 15cm coolermasters for circling cold air inside

 

[Nepsilon]

Update : I ran prime again for 1 hour and at 16th minute temperatures raised to 85 on 1 cpu , others 81-84 and the PC froze.
I couldnt restart or do anything , i had to turn it off fully.

I guess this is some kind of temperature protection or ?

I have downgraded it do 3.8 temperatures still exceed 80C with prime but while in-game i am having 50-54 max C temperature and the PC isnt freezing.

Can i please get any advice on this ?

Thank you

Welcome to OCN !

First go here ---> http://www.overclock.net/specs.php?do=addsystem and fill in your system specs.

I think the best advice I can give you at this point is to check these out.

running prime for 10 minutes won't stress it long or hard enough.

8-24 hours of continuous prime and large FFTs would be an almost fail-proof test

Thank you for your replies . I have filled in the speccs , and as also read both of the articles.

I just wanted to know if my mobo automatic OCing is safe or i should go step by step by myself in the Bios.

I`ve read that increasing the bus speed will give me more temperature instead of increasing the multiplier.

My last question is , around what temperature degree i should be sticking if i go with

21 multiplier with 190 bus ?
Will it drop to 4-5C degree or its not even worth trying ?

About OCing i will sit for 24 hours on it and i will do it somehow.
I just want to know the limits of the temperature and why my PC didnt turned off but froze while running Prime ?

Thank you

Below 100 You're safe. But my personal limit is 80-85 degrees max. So my advice is, stick with those temps. After your PC freezed did You have any BSOD report?

No i didnt had anything, turned it off and it ran normally without saying anything.

This is on what i am atm. You can check if there is something wrong

On temps, keep the temp of the cores below 80C while testing as measured with Realtemp, coretemp, or HWMonitor. This is what I shoot for.

Automatic overclocking is usually safe but far from ideal. I wouldn't trust it though. Much better to overclock in BIOS.

@ 4.0 my 760 prefers 191X21 to anything else. Each cpu is a little different though and yours might like 200X20 better. The temp differences come into play when it takes extra voltage to get one stable over the other. From what I've seen your going to be much better off keeping your baseclock below 200-205. Mine at least starts getting tempermental and power hungry around 204 and I've seen others have the same issue.

If it freezes it is almost always an instability on the uncore side rather that be the RAM itself or more likely the memory controller.

 

[sp4wners]

Can You post Your BIOS photos? Settings You have used for Your CPU, RAM etc. This program don't tell me anything.

 

[Nepsilon]

Okay thank you very much i will try with 20x200 or 191x21.
I know i will fail more than 10 hours starting the PC because this will be my 1st OCing.

Other than that i am asking myself if it could be a PSU power.

My GPU is taking a lot of power and now the new mobo + CPU might be killing the PSU.

 

[Nepsilon]

I will make Bios pics and i will post them till tonight.

The freeze was most likely caused by an unstable overclock.You really shouldn't push 4.0 without an extensive knowledge of what you are doing.Having the bios set to auto when you're overclocking can cause much higher temps than normal.It would be best to use your bios only.

^-- This

I know, I know, nearly everybody likes a quick and dirty overclock there first time. BUT you will be much better off at least following that little guide I wrote for the i5 760 OC Club. aka pretty much find your stock vcore and slowly work your way up from there. Or go all out and follow miahallen's Lynnfield guide. It's actully faster then messing around trying random settings.

If this is all you changed in the BIOS then I can certainly see why your computer froze after stress testing. I'm guessing your QPI/VTT, uncore multi, uncore volt and ram settings (besides voltage, which is too high) are all set to auto? That is a bigggg no no. As others have said please post your BIOS screen shots so we can get to work on the OC.

 

[sp4wners]

Just post Your settings. As kschat said, just read the post above mine. If You're overclocking an Intel CPu like Core i5 or Core i7 you should incerase Your QPI/VTT, ram, ioh, ich etc. voltages too. As I said just post Your settings and You'll probably get full stable 4GHz today

 

[Nepsilon]

I am very sorry for the delay but these 2 days were all rushy for me at work. I will post the bios pics Friday morning.
Once again i apologize.

 

[Nepsilon]

As promised , here are the Bios pictures.

I hope this will help. If i have missed anything please tell me.
