I'll try it, so I understand that you have the same board as me? Which LLC setting do you use?
Thanks

SA goes much higher in 10.5 I never messed with it in 10.3 so I can't comment on that. I use 100%. I would recommend using a lower setting if your staying on auto for volts. Anything less than 100% your going to pull your hair out as your load volts will be much lower than what you set in bios. Since we don't have an offset setting on this board its pointless to use anything less than 100%.

I just use IBT anyway, no need for prime stability imo.

If my machine can do 25 runs of IBT with max ram then that's good enough for me and will not give any problems.

That's not 100% true my friend, I can pass 50 IBT loops but my system fails at Prime95, indicates that it is unstable. You take the risk of file corruption in case your CPU is unstable, Prime is a much more reliable and thorough test than IBT and should be ran for a long period of time to achieve stability if you ask me...

Dude please... You won't get file curruption.... IBT is more then enough to test an overclock.

Some of us actually want to use our computers and not sit around for 24hrs.

And on the flip side I've had prime95 stable and failed IBT.

Success!!! Finally, I was able to stabilize 4.6 GHz!

I updated my BIOS to 10.5
Set voltages:

Vcore to 1.43 (1.4 in CPU-Z)
I/O - 1.07
S/A - 0.97
PLL - 1.84

I also set the Short and Long Duration Power Limit values to 200 and 255 respectively and set the maintained time to 30 seconds before disabling EIST, then I disabled EIST so the values should be saved in the background.

Managed to run Prime95 blend for a full 12 hours without a single error and it finished a full cycle of tests from the smallest to the largest FFT, relief! Also ran IBT for 10 passes on Maximum and it passed, finally I can call this config stable, this is enough for me.

Would like to hear your opinion about my current voltages and stability on 4.6, thanks.

People at the MSI forums told me that my Vcore is too high, I can lower the Vcore to below 1.4 and stabilize IBT at 4.6 GHz, I've managed to do that with 1.37, the question is, will it be really stable and can I rely on my PC based only on IBT. The guys there say that it should be more than enough to verify that your overclock is stable since nothing will stress the CPU so much.

The temps difference was about 5C lower with the regular version of Prime as compared to the 27.7 AVX version, not that big, GFlops scores were the same, 130 seconds for a loop and 120GFlops on average, I didn't take a screenshot. Max temp in both P95 and IBT reached about 70-74C.

Besides, why is the AVX version of P95 so important and how many of you i5 owners actually used it for your stress testing? It seems like the AVX version of P95 is a little too harsh...

Thanks

Try more vcore running prime 12 hours atleast right? and more for 4.6 GHZ is normal my chip needs around 1.415 to be stable prime 24 hours and ibt x 100 standard.

Ok, another update, I've decided not to cross 1.4V in the BIOS so I decided I'm gonna try 4.5GHz and lowered the voltages as follows:

Vcore - 1.4 (1.384 in CPU-Z idle, 1.368 load)
I/O - 1.07
S/A - 0.95
PLL - 1.82
DRAM - 1.514

I then tested P95 AVX 27.7 Blend test which ran successfully for a full 12 hours! Check out the screenshot:

re2w5.jpg

Which really surprised me, I was sure I'm gonna get a BSOD but it passed.
Then I ran IBT for 10 loops on Maximum to finish it off and it passed as well:

hujz7.jpg

I'm very pleased with this, I was able to lower the Vcore by 0.3V, lower the PLL and S/A and still get it stable on 4.5GHz

The difference in performance between 4.5 to 4.6 will be invisible, plus I've read several reviews which proved that there is hardly a difference if any at all in gaming or benchmarks so I'm fine with 4.5GHz at 1.4 Vcore.
I think I'm gonna settle down with 4.5 GHz it's a very nice 30% overclock to an already very powerful CPU, no need to push it to 5.0 and try to fry the CPU with high voltages

What do you think?

P.S.

For some reason, MSI Click BIOS and Control Center still show my S/A voltage as 1.05 even though I have it set to 0.95 in the BIOS manually, I know that the limit is somewhere at 1.2 so even if it's true I'm fine, but still, it's weird, anyone else experienced this? I would hate to find out that this voltage spikes for no reason...

Thanks

Yeah true your chip will need a lot less for 4.5, similar to mine. I only need 1.330 for 4.5 ghz.
