benchmark.kz Posted August 10, 2013 Share Posted August 10, 2013 (edited) 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? video Edited August 11, 2013 by benchmark.kz video added Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted August 10, 2013 Share Posted August 10, 2013 Not incredibly helpful, but get a better board Quote Link to comment Share on other sites More sharing options...
Mikecdm Posted August 10, 2013 Share Posted August 10, 2013 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. Quote Link to comment Share on other sites More sharing options...

nedernakker Posted August 10, 2013 Share Posted August 10, 2013 Are you sure you have all the OCP OVP settings in the right order? Sounds like an OVP/OCP Quote Link to comment Share on other sites More sharing options...

Sounds like an OVP/OCP It's really sounds like as OVP/OCP, but it is disabled in BIOS. I swear. Quote Link to comment Share on other sites More sharing options...
benchmark.kz Posted August 10, 2013 Author Share Posted August 10, 2013 also tryed different fiVR freq (300-350-400 MHz) and Vdroop (15%-50%-75%-100%). Not helps. Quote Link to comment Share on other sites More sharing options...
[DRACO] Posted August 10, 2013 Share Posted August 10, 2013 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 Quote Link to comment Share on other sites More sharing options...
Mikecdm Posted August 10, 2013 Share Posted August 10, 2013 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. Quote Link to comment Share on other sites More sharing options...
benchmark.kz Posted August 11, 2013 Author Share Posted August 11, 2013 Mikecdm, thanks, will try lastest 1.3 version. Will report here, helps/or not. Quote Link to comment Share on other sites More sharing options...
der8auer Posted August 11, 2013 Share Posted August 11, 2013 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. Quote Link to comment Share on other sites More sharing options...

It's seems you using MPower Max, not MPower Edited August 11, 2013 by benchmark.kz Quote Link to comment Share on other sites More sharing options...
nedernakker Posted August 11, 2013 Share Posted August 11, 2013 Under the cpu settings in the oc tab, put the core current to 200. this should solve the issue Quote Link to comment Share on other sites More sharing options...

It can be only auto or enhanced. OverVoltage setings is 500mV Edited August 11, 2013 by benchmark.kz Quote Link to comment Share on other sites More sharing options...

I also got the MPower Max and XPower here but those have a different bios.

Crew Leeghoofd Posted August 11, 2013 Crew Share Posted August 11, 2013 could this be PSU related ? Coolermaster 800W ? you are pumping some nutty voltages there man for them clocks... Quote Link to comment Share on other sites More sharing options...
benchmark.kz Posted August 11, 2013 Author Share Posted August 11, 2013 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.

TerraRaptor Posted August 11, 2013 Share Posted August 11, 2013 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. Quote Link to comment Share on other sites More sharing options...
Crew Leeghoofd Posted August 11, 2013 Crew Share Posted August 11, 2013 well my old AX1200 did stuff like that too sometimes, sometimes flawless then all of the sudden she went down... Quote Link to comment Share on other sites More sharing options...
