As for stability, show me you being unstable at (for example) 200x20, but stable at 220x20 at the same voltage. It doesn't work that way. Adding FSB does not increase stability. Lowering the multi and using FSB to make up those clocks does.

Lowering multiplier or increasing FSB to achieve the same overclocks is essentially the same lol.

^This would end up with a higher overclock because you didnt lower the multiplier... I never said you shouldnt lower multiplier.

No, you just completely left it out;

No mention at all of lowering multiplier. None.

We get a lot of new people here. They will read that as "All you have to do is increase the FSB and it'll become more stable", and that is not the case.

The test doesnt always stop lol i can guarantee you that negative results are unstable. I have been using IBT AVX for a long time now and i used to think negative results were ok until i tried video encoding and pc would crash. Its passed you because you are close to the required voltage. Just not quite there.

Bump up your volts a notch or 2 and you will see positive results again. a few notches below and i think you will fail the test

Never stated that was all they had to do. Also i was helping somewhat knowledgable guys who allready did some overclocking. Im pretty sure they understand that they should lower the multiplier if increasing FSB to stay on the same speeds.

Dont be difficult now. I think you know what i mean.

Hi peeps, after some advice, I can manage a pretty stable set-up at 4.4 by increasing multi x22 and upping the CPU V to 1.4870 using MSI control centre
but if I try anything higher Prime95 bombs on one or two cores.

The only other changes from stock is disabled CnQ, for some strange reason with this on, I get like a shimmer on the screen!?
and set the RAM to DDR-1600 with 1.57V and disabled EUP as recommended on the MSI forums.

I'd like to try and hit a stable 24x7 around the 4.6/4.7 mark, but at the very edge of my very limited knoweldge.

My set-up is in my sig below.

TIA

Im gonna say it... Try to lower the multiplier a bit and increase the FSB. Might help you. It helped me.

It gets those results regardless of the clock speed. Even at absolute stock settings its exactly the same. Anyways, you missed the part where it was a SUICIDE RUN and not my daily OC to begin with. I just wanted to see if it would do it. Come to find out that is about the limit, it won't get into windows at 5200 no matter how much voltage there is.

Thank you.

Anyway, guy is on an MSI board. No LLC, and insane vdroop, he needs to compensate by knowing his load voltage, not what voltage he set. Odds are he's dropping too low when under load, not that his settings are bad.

Lots of things to take into consideration when helping someone. Other things include;

Some ASUS boards don't like a multi above 23.5.
PLL to 2.6-2.695v on Giga can reduce needed Vcore by .025v.
Some Giga boards do not like to FSB OC at all.
Giga 3.0 boards have HPC to work around.

and more I cant remember off the top of my head. Quite a bit more to it then just Vcore, FSB, and multi. wink.gif

Also found that the ASUS Equievelant of PLL (CPUVDDA) at 2.6V instead of 2.5 can increase stability in certain stituations.

Thats crappy it wont hit 5.2

anyhow mate i wasn't trying to be funny or anything so don't think that lol. i just didnt want you to be under false illusions...i try to help and explain the best i can. This thread keeps me from going psychotic biggrin.gif
If you get negative results anyhow then there is something a bit wrong, though if it stable for your daily usage then there's nothing else to say smile.gif

Anyone running a non LLC equipped board needs to gain a good understanding of how much Vdroop their particular board has at load, for my gd-80 v2 , its .07 volts . I'm gonna guess that he is only running 1.41 volts at load with the settings above . Try running OCCT for yourself and see how much Vdroop you get Monty, the graphs will help you smile.gif. If your target is 4.8 ghz, you will probably need to set your voltage to 1.536 or more in control center to be stable, which is fine ( in my opinion) as far as the vish is concerned , as long as you keep temps cool .
