I am having trouble keeping the Multiplier set. when I go above 48X say like 49 or 50 or 51 system boots but when I apply load to cpu the multi down clocks to 48x.If I use 48x or less then under load it stays where it is set.
When i first set up the board it has bios 18.1, now I have 18.4 The shipped bios did not seem to have this issue.
I need to find setting in bios to fix this issue.here are some screen shots.

Recommend to reflash to the version that was working correctly & notify MSI Tech Support of what you have experienced with those other versions; http://support.msi.com/

I need to find setting in bios to fix this issue.

Don't believe a setting exists that will fix this. It will require a completely new version release from the engineers.

Unfortunately I do not have any bios versions other than the 2 listed on there download page

Another aspect I noticed is when using the default setting in the bios the turbo boost feature is only going up to 3.5 instead of 3.8 so some basic setting needs adjusted in the bios defaults to correct this.


Other than a few small issues this board works good and seems much improvement over the other 2 companys boards I used.

Have a look in the 'OC' UEFI Section, 'CPU Features', & see how the 1 through 4 Core Ratio's are set up.

Added: What is your complete system comprised of?

2nd add: MSI Tech Support should be able to send you a 18.1 to flash back to; http://support.msi.com/

I will contact them and see.

System:
Z68A-GD80 (G3)
2600K
4-4GB Kingston HyperX 1600
2-Evga GTX 570's
256GB Crucial M4 SSD
1000W Xion powersupply

So I flashed back to 18.3 and confirmed that the turbo boost is still only working up to 3.5 using default settings in bios.I also confirmed that 47x is the highest multi that does not throttle back under load.

Please keep the forum updated when Tech Support responds. Hopefully reverting back to version 18.1 solves it. Unless a newer revision offers any benefit to your current system configuration, there is no real point in flashing it.

No response on my service ticket yet, so I called and talked to a tech he was kind enough to email me a beta bios.He never really understood my issue I think,I tried to explain first the the default settings in bios do not let the 2600K turbo work correctly stopping it at 3.5 instead of 3.8 second was that under load above 47x system down clocks.But the beta bios addressed partial problem,so i was grateful.

Couple things about beta bios, first was after the flash my Cooler master SGM-4000-KLLN1 mouse was all wonky in msi click bios II seemed like the sensitivity was to way grand and the axis was off.This mouse worked fine on the previouse bios no issue.Fix is to use standard logitec mouse and that function good.

Using default settings the turbo boost still never make it to 3.8 but did go 3.6-3.7 this time around.MSI has the turbo ratio set to 38,37,36,35 by default when it should be set to 38x on all cores this allows the turbo to function correctly. now that I pin point the turbo issue I do not know on other bios if changing this setting to 38x on all cores will have same result i will test tonight.

The throttling is better controlled with this beta bios on the higher ratio's, the direct adjustment for this is the Long & short load limit. This adjustment on the other bios had no effect so this is a Great improvement. I was so pleased with this detail that I went alittle sideways,this led me to learn a few new aspects of the board settings.

The "Intel C state" setting is on by default but as a user fiddles with other settings this settings gets auto changed.Now I un sure exactly which other settings indirectly triggers the auto disabling of this feature but it hinders the ratio past 48x. I will try to button this out tonight , see what other settings auto change the C state to disable. C state has to be enabled to get High ratio's to work.

The feature "enable ratio change in windows" is disabled by default in this beta bios when enabled it caps the ratio at 34x in previous bios this was not the case.

There is so much more but I need a relax, i will do some more testing and posting to night.

Keep the forum updated with your findings.

Final result from new beta Bios is CPU ratio above 47x will  not stay where user chooses, no matter the settings. Once a load is applied it down clocks to a lesser value the value is load dependent the higher the load the lower the value.

Turning off all power state settings one at a time till they are all disabled.
1.disable intel C-State = 49x max ratio even though 52X is still chosen and turbo 52x on too.
2.disable turbo mode = 50x max ratio only if you follow this order. Turn off turbo before Cstate and stuck @49x
3.Rest power state settings make no difference 50x max but same issue when load is given ratio drops.

Screens to large had to post links, bottom line I still needing some love from MSI & I still waiting for a response to my ticket.

Now that I have some thought, technically my issue is not a ratio problem. Ha

Now I see more clear I understand it to be a wattage draw issue.The only settings I know associated is the Long and short duration power Limit.

Using core temps wattage draw Estimate I can watch the throttling occur and certain wattages.So the calibration is a bit off at default 95w the core starts throttling at around 89W so I am thinking off by 5% that at the low end.The high end 255w seems off by larger percentage I am guessing 10%. I am no smarty but from what I know I see no fix for this since the whole power draw scheme on the board would need changed.Surly there is much I do not know so be easy on me.
