"You can make it incredibly complicated if you'd like, but this is all you need to do:

1. Set everything in BIOS back to defaults.
2. Turn "turbo boost" off.
3. Feed it 1.4v.
4. Set multiplier at 45x.
5. Run OCCT auto 1hr
6. Report back."
I ran OCCT linpack auto 1hr no errors. Temps got a bit toasty though at 68-75 degrees. I notice they only get into high 70s when the vcore is a bit high such as 1.4 but in normal gaming they are most likely under 70. Interestingly enough i got bsod 101 from doing normal tasks.

You know why I require such a high vcore to reach this oc of 4.5ghz while some people can hit it at 1.28?

chips are not made equal, every single chip is different.

After ignoring some of the comments from before, doesn't seem like no one really made an effort to help out. Some are very quick to critisize.


Anyways how about you post your BIOS settings here as they are right now and then we'll take it from there. I'll try my best to help you out right now.

Thank you and everyone else for trying to help. I have attached the bios settings and I am going to run prime blend overnight and hope I dont see a restarted desktop.

settings look fine, however, the things that obviously stand out is the fact that you need PLL overvoltage enabled for that multiplier and require almost 1.4v just for a 4.5ghz overclock. Normally I advise working up rather than down, however it may better to work down in this instance. If you find that you're stable then you can start reducing that vcore and retesting with prime blend, however I do still think that you should start small and work your way up. something like 4.2ghz with 1.3v, test with prime then increase multi until it shows sign of instability then increase the vcore by small increments untill you reach a 'limit'

By the way did you set the turbo power limits? Also you might want to increase the dram voltage a notch or two to get it at 1.5v because at the moment it's at 1.488v, that could be what is causing you problems, that 0.02 of a difference can make or break stability.

Also what options do you get under vdroop control?

Enable C1E and speedstep to ensure that the multi drops when it's at idel, it doesn't effect stability.

Well my computer restarted overnight and I will try 4.2ghz at 1.3. I did not set the turbo power limits should I set them to 45? Under vdroop control is auto and low. Should I reset the cmos? Where can I find speedstep?

After how long did it fail and what was the bsod code?

Could you post ALL the pages / options available in your BIOS. Thanks

Speedstep is EIST should be under the safety features (cpu configuration I think). Have you tried Vdroop on auto? it may help reduce vdroop when your cpu is under load. Reset the CMOS if the BIOS is acting a little 'weird', no harm in doing so.

Setting the turbo limits allows overclocking without any restrictions, setting the 'current' allows the spu to erceive what's needed for a particular overclock. Apologies but im not so familiar with MSI mobo's so if you could post all the BIOS settings then that would greatly help.

Thanks

I am not sure how long it failed because i was asleep and for some reason i don't get a bsod windows 7 msg I just restart back into my normal desktop. I will try resetting the cmos and the vdroop is on auto and ill take the pictures. I also failed a prime 95 blend at 4.2 1.3v
