MSI Z77 Mpower owners club / All things MPower - Page 167

post #1661 of 3633
Got a bit of a problem here.

When board was stock my 3570k would idle at 1.6GHz with a voltage of about 0.9xx. When it was loaded it would ramp up to 3.8Ghz (I think) and the voltage would rise, this was probably using auto-voltage.

I had a fiddle with the core ratio, both on the main page and the 4 ratios under CPU features, and now whilst I can adjust the overclock and the CPU does downclock to 1.6GHz, the voltage remains at the 1.150v I have manually set in the BIOS and won't drop when the CPU downclocks.

I've got C-states enabled, C1E support enabled, EIST enabled, turbo etc.

Is this a bug? I also had problems with C-state settings not sticking sometimes, although they seem to have stuck now. Evidently something that claims it is active obviously isn't if the voltage won't drop. Is it anything to do with setting the power management options to "custom"

I'm try to overclock via the BIOS under the standard settings page, but I don't really want to carry on until I can make the voltage drop when the CPU isn't loaded.

Hi, does anyone use a Creative Sound Blaster Z-Series card with this motherboard without issues? I seem to have an issue where I cannot install the card (though Windows sees it as HD Audio Device). It's an issue SPECIFIC to this computer with the Z77 MPower 2700K system and the card works in my other X79 Deluxe 3930K system.

from Another's findings


No. actually it doesn't.

We implement CPU offset voltage differently and from an overclocking perspective, apparantly better.

In ClickBIOS, go to "Hybrid Digital Power"

And there you can select your offset options, control and compensation.

Set VDroop Offset control to 100% (100% of the set voltage at maximum CPU speed) set Digital Compensation to High and just leave EIST enabled.

This leaves the Load Line Calibration settings at 100% when you set your voltages you want for OC and the system will do the rest.

As you can see from the table below (4.8 GHz LinX) this gives you lower power consumption vs. Asus/Gigabyte, lower temperatures and better performance.

oh .. and NO VCORE fluctuation.

I'm not sure how that helps my problem of the Vcore not lowering whilst the CPU is idle.

Doesn't LLC deal with droop of Vcore under load? My problem is that Vcore won't drop when Idle.

Sorry if I don't understand the relevance of what you've posted. Maybe you can explain.

Yeah i think I get what y mean.

Well try it at Auto for cpu voltage with the above settings see if it cpu voltage changes a bit as it processor scales up and down
Other than that I don't believe there is a same/specific offset voltage thingy as A*** boards
Its done a bit different.

I am so close to just throwing this motherboard into the trash. I've had nothing but random problems it... (and yes I have the latest bios installed)

- Loss of signal during reboot a regular issue
- Multiple times now I've lost a storage hard drive from changing a setting in the bios and having disk check run at Windows boot and screw things up (MSI Fast Boot was the last culprit)
- Can't get a sound card to work
- 2-3 boot loops after changing settings sometimes
- Doesn't have proper offset voltage

When things finally work, I don't dare touch anything in the bios anymore. What a frustrating thing this board has been. I don't care how well my motherboard overclocks when it literally can't do anything else right. mad.gif

what bios y on?
I wouldn't get to uptight about offset voltage my A*** pro was a a pain and it had it.
As for windows disk check let it finish and its done and most likely won't bother again unless a disc issue, had that here on many boards

DRAM voltage is set to 1.525v. thumb.gif





I swapped BIOS around 2-3 times and couldn't get the BCLK to over clock. Finally after going back and forth from old to new BIOS and having the same results I set my ram to 1333mhz CL 11 and set CPU to 5GHZ. Booted fine. Set RAM to 2200mhz with BCLK 102mhz for effective 5 GHZ with multi of 49 on CPU and booted and ram and CPU didn't take BCLK over clock. I powered down. Swapped my ram sticks around from the ram slots they were in and then it booted about 3 times and cycled through its start up with no image on display. Finally on the 4th reboot. (I just let it start up and shot off then start up by itself) it booted into Windows and the BCLK took effect on the RAM and CPU speed as posted above.


I blame the BIOS to be buggy with the Samsung Green HYKO IC based ram that I am using. It's working now and hopefully it sticks for awhile. I'm sure the RAM can go alot faster in an ASUS MOtherboard which over clocks HYKO ram like a champ. Please MSI fix the BIOS to fully support the SAmsun Green 30nm HYKO based ram.


That was last night. This morning when i started up my RIG it went back to not over clocking the BCLK. frown.gif


I swapped out Samsung Green to some Gskill 2400mhz to see if it may be the ram and that didn't work. SPent about an hour tweaking trying different BIOS options and nothing. The BCLK is stuck at 10000 every time regardless of what I manually set it at. mad.gif


I think the new BIOS CPU features of "Hardware Prefetcher" item and "Adjacent Cache Line Prefetch" options are part of the problem. When I disable hardware prefetcher my memory performance shoots way down. BUGGY!!!!

MSI fix the BIOS!!!
