MSI P55 Series *Official* Motherboard thread

What on earth is going on here. I set up what seems to be a reasonable overclock (one that's worked previously), F10 and reboot.

At the restart, the whole POST bit seems to get skipped -- USB drivers don't get loaded, for example. Then Windows fails to load, the PC reboots itself, POST gets skipped a second time, Windows asks me "launch startup repair, or start normally", and, because nothing has loaded any USB drivers, I'm unable even make a selection!

My only resort is to clear the CMOS. Very annoying. And strange. I've not updated the BIOS version or anything.

Anyone seen anything similar?
 
OK, something weird is going on. Now, when I set the XMP on auto, if I go straight back into the BIOS, it tells me current RAM speeds are 7-7-7-24. These should be 9-9-9-28 (and I'm sure they used to be!). WTF?
 
Hey guys,

I'm having a problem with my BIOS settings. If I load optimized defaults, then slacken just the memory timings (in preparation for overclocking, but don't actually change the base frequency yet), save settings and reboot...

When I come back into the BIOS, the changes to the RAM timings haven't been set! Obviously, if this happens when I've also increased the base frequency, the overclock fails, and I have to start all over again. At the moment, I seem unable to get it to save the memory timings at all. :rolleyes:

BIOS v1.4. Am I alone in this experience?

bios auto values don't mean much, check the value in gpu-z in windows

Pretty certain now that this is the same problem I posted about just a few seconds before you posted this. :) As far as I can see, it's a definite problem with the BIOS/board failing to save the settings I'm giving it? :confused:

EDIT: Also just tried saving required memory timings and, instead of going straight back into the BIOS, loading Windows. FAIL: CPU-Z reports the default timings are still in effect. :mad:

FYI, through a whole lot of trial and error, I think I've figured out what I was doing "wrong". Normally, after loading optimized defaults, I would set the OC retry count to 1, figuring "if it fails, it fails". Apparently, this need to be 3 for the system to boot with even a mild overclock? :confused:

Thanks for the heads up!

Will get this on tonight. Seems to be a fair few fixes!

- Update CPU micro code.
- Update NB module.
- Update M-Flash module.
- Improved VGA compatibility.
- Improved memory compatibility.
- Fixed system report incorrect memory size when install 4G memory.
 
Definitely better than 1.5 as I've been able to run all day with my usual overclock. 1.5 wouldn't even boot into windows at this speed.

Haven't done any proper stress testing though.
 
I just upgraded from 1.4 to 1.6. My saved overclock profile was "invalid". When I set it up again, it failed to boot. I may have made a mistake, as I'm very tired. I'll try again tomorrow.
 
Yeah the format has changed since 1.4. Make sure you check:

-Voltages including chipset, memory etc
-RAM divider/timings
-Vdroop setting
-Spread spectrum, OC Genie, overclock button, turbo boost, all the power saving stuff etc

Problem is when you flash the BIOS all this stuff gets reset and it's easy to forget some of the more obscure settings
 
There's something different, for sure. Before, I was running my RAM at 2000 MHz; now, I can only manage 1600 MHz.

Seems to be with my memory timings. I was using the timings from the XMP (Geil RAM) (but running at 2000, rather than 2133). Even if I set those (i.e., loosening everything from "auto", I think) with a 3x multiplier (1200 MHz), the PC fails to boot.

Actually, I haven't managed to get the PC to boot with the timings set to manual. So far, it's only happy if I leave it on auto!

Ive just gone from the stock bios to 1.6. When i first applied my overclock settings on the 1.6 bios the board also failed to boot. Tried 3 times then reset etc. When it reset i went into bios, didnt change a thing, saved and came out. Booted perfectly and been stable since.

When you go into the BIOS (via F1) after a failed overclock, I've found that things aren't set as they were before, i.e., the settings you see after a failed overclock might not be the settings of the failed overclock. (Memory timings have a particular tendency to change.)

I think I'm going to have to content myself with running my RAM at 1600 MHz, using auto (7-7-7-24) timings. I can't get the thing to boot if I set RAM timings to manual -- even if I don't actually change anything and set the lowest multiplier possible! (With 1.4, I was running 9-9-9-28 @ 2000 MHz.)
