Strange bug with MSI Z87 Mpower

[benchmark.kz]

Hi all.

 

I have a strange bug with MSI Z87 Mpower under LN2.

 

I have an air preset, fully stable. Here is it:

 

CPU Ratio x47

Uncore Ratio x39

VCCIN 1.8

VCORE 1.27

VCCSA +0.2

DRAM 2400 MHz @Cl9 1.95v (PSC, Memtest ok)

PLL Filter Enabled (SB PLL)

Power Limits 4096

 

OVP, OCP, C State, EIST, Intel Thermal Control, VID Connection & etc are disabled.

4cores|8 Threads

 

So, I booting with that profile. Temps on LN2 Pot is about -80.

I set up VCCIN to 2.3, after CPU Voltage to 1.75 volts without increasing ratio. After that all motherboard immediately shuts down. No bsod, no reboot, just shut down.

 

If I set lower voltage, for example 1.5, it's works and allows overclock. 1.6 same as 1.7 but not always.

 

Used bioses:

1.4b3

1.4b4

1.4

1.2

 

Any ideas?

Not incredibly helpful, but get a better board

I tried 1.43b and could run fine on air but it didnt run cold. Not sure if it was voltage or temp related. On 1.2 it runs fine but bclk doesnt work. Pretty sure it was 1.2 or something close. Never figured out a good solution.

On air works fine too.

I have a same think, but, may be, anybody have a magic trick to make it works.

Are you sure you have all the OCP OVP settings in the right order?

 

Sounds like an OVP/OCP

It's really sounds like as OVP/OCP, but it is disabled in BIOS. I swear.

also tryed different fiVR freq (300-350-400 MHz) and Vdroop (15%-50%-75%-100%). Not helps.

brother,

 

I have also tried Mpower with ln2 and I was pretty bad,

 

In xTU 5ghz turned off until I do not understand why.

 

I've tried some different things bios and bios.

 

Nothing helped to be stable.

 

Very different from the xpower that is far more stable.

 

I hope it will be your

Apparently I used V1.3 for everything. I did all of my MOA subs with that bios and chip ran pretty strong. The only downfall was that bclk changes would lock up system within windows and that i couldn't boot with anything other than 100. I put 1.43 on the 2nd bios and bclk worked fine when testing on air but as soon as I tried ln2 it wouldn't work. Since I had the pot cold already, i flipped the switch and just ran V1.3 with 100 bclk. None of this is taking into consideration obvious issues such as psc not working at 2600 or 2666. Matter of fact, I'm pretty sure the 2600 strap is broken.

Mikecdm, thanks, will try lastest 1.3 version. Will report here, helps/or not.

My MPower works fine. Can do 1,85 Volt without problem and already benched at 6,3 GHz without problems. Using E7815IMS.123 BIOS without problems.

Where I can download it? In bios list it is absent. It's seems you using MPower Max, not MPower

Under the cpu settings in the oc tab, put the core current to 200. this should solve the issue

You mean CPU Core OverCurrent protection? It can be only auto or enhanced. OverVoltage setings is 500mV

No it's the normal MPower. I also got the MPower Max and XPower here but those have a different bios.

Thanks, will try to use it. But Regullar Mpower bios marked as 7818, not 7815

No, my board doesn't allow to flash 7815

Here is a video wihth system shudown.

on video it is shutting down at 5.5 Ghz, but these shudowns so randomized and they can be also at 4.7 Ghz

No, I mean in the oc tab, all the way down to CPU features, then set CPU Current Limit (A) to 200

I was setup up there 1024A. 200A doesn't help too.

could this be PSU related ? Coolermaster 800W ? you are pumping some nutty voltages there man for them clocks...

Yes, It is CoolerMaster Silent Pro 800W Gold. Tryed to use Thotech Thunderbolt 850W - same. Next week will try to use Maximus 6 Extreme with that CPU, will see.

well, John had runs on >6ghz i3770 with overclocked 7970 on the same power supply. It is strange that system shuts down even with cpu idle - just with the vcore rised.

[Leeghoofd]

well my old AX1200 did stuff like that too sometimes, sometimes flawless then all of the sudden she went down...
