GA-P55 UD3 Cold boot BSOD problem

Re: GA-P55 UD3 Cold boot BSOD problem

OK, qpi was definitely a bit low, so i've upped that to within .5, however I can't now recreate the memtest errors I was getting previously (and I was literally getting a hundred or so after a few seconds). Still, currently 8-8-8-24 at 1.66 volts (there's no option for 1.65), and no immediate memtest errors, so I'm not complaining. I'll see how the cold boot goes in the morning.

Cool, let us know how your further testing goes and if you need anymore help.

Good luck with the tweaking and testing!

Re: GA-P55 UD3 Cold boot BSOD problem

Didn't get a cold boot bsod in the morning (twice in a row - a record), but it did blue screen at some point this afternoon with a 0x000001A error, so I've upped the qpi a notch again. Will see how it goes tomorrow before trying an overclock.

Re: GA-P55 UD3 Cold boot BSOD problem

Great to hear! Keep us posted

[simongwynne]

Re: GA-P55 UD3 Cold boot BSOD problem

Well, the last two mornings I've had 0x0000007E blue screens, so further tweaking is required.

Re: GA-P55 UD3 Cold boot BSOD problem

Well, let us have your settings and we can advise.

Unless you are further tweaking yourself, if that is the case keep at it and let us know how things go and or if you need more help

Re: GA-P55 UD3 Cold boot BSOD problem

Don't know if this helps anybody, but having problems with cold boot BSODs on a new system for a week now seems solved for me.

System :
GA-P55-UD3,
Core i5 750,
4 GB Ram,
NVidia GTX 275,
64 GB SATA SSD,
SATA DVD,
Windows 7.
Bios f5 set to "optimized defaults".

Symptom: Nearly Every cold boot ( 80%?) into Windows7 ended in a reset-like crash ( e.g. the machine behaved as if reset was pressed: black screen, and POST) or an A1 ( Memory Management) BSOD.

Solution: In the Bios there was a floppy set to 1,44MB 3,5" while there was no floppy actually attached to the system...

After setting this to "None" I had around 20 cold boots, restarts and S3 sleeps wihout a single BSOD or Reset.

I know this sounds rather trivial ( compared to the settings that were already dicussed in this thread ), but may be worth a shot ...

Hope this helps
Eric

Edit:
Forget this advice. After 3 days without a single problem the system started to crash again ( 4x on cold boot and 3x during win7 BSOD 1A and 3B) this morning.
This time I was able to log errors with memtest86+, so faulty RAM seems to be the root cause.
However, the error is intermittent: 5 double passes of memtest went OK, the sixth boot/memtest showed the errors.
Going for RMA for the RAM.
However, another possibility would be a board/BIOS issue or possibly even the power unit...

Bye
Eric

Re: GA-P55 UD3 Cold boot BSOD problem

Greetings from a fellow P55 UD3 user with cold boot bsod issues. I even tried the 1.44 floppy disable setting suggested with no success. BIOS flashed to F5. Latest drivers for gfx, audio.

I think that the constant bsod's on EVERY cold boot have corrupted a file or two as some features of W7 no longer work so will be doing a reinstall of the OS this weekend. (LIVE Mail, Windows update and DirectX installations (tried this as well...) are the most obvious programmes responding with nasty messages.

I am not an over-clocker and with my setup and the games I play (Crysis being the strongest demanding, Fallout 3, HL2 etc) I shouldn't need to OC. I just want a stable system on first boot.

Memtest has been run fine on a warm boot but generates masses of errors on any cold-boot. I believe that there is a compatability problem with the default settings between the mobo and the ram but that is conjecture. All my ram is 1600MHz but the system sees it as 1333. It will/should still run fine but I am thinking that there may be voltage issues there somewhere.

Any light you can shed or guidance you could provide would be massively appreciated.

Re: GA-P55 UD3 Cold boot BSOD problem

Looks like we have very similar systems, and probably the same RAM. Does indeed sound like an incompatibility issue.

Re: GA-P55 UD3 Cold boot BSOD problem

Hi,
looks like I'm having a quite similar problem. My setup is:
P55-UD3 F5+ Core i7 860 + 2x 2GB GEIL GV34GB1333C7DC

Even without any overclocking, i.e. with Fail Safe Defaults of Optimized Defaults settings, the system runs not at all stable.
There can happen thausend of memerory errors when booting into memtest86+. Also user space memtester-4.0.7. causes a system freeze quite frequently.
On the other hand, it also passed 20 passes of memtest86+ without errors the other day, but I've absolutely no clue what make it fail and what not.

I tried a couple of settings, mainly regarding the DRAM frequency and voltage settings. The RAM default is at 1333MHz CL 7-7-7-24. I relaxed theese settings down to 800MHz and 9-9-9-36, which still led to failure ocassionly. Further I experimented with the DRAM voltage with no sustainable success.

However I noticed some strange effects which I don't know if they are bugs actually or "features".

First I tried hard to setup 1.5V DRAM voltage, because I read in the memory specs and elsewhere on the web, that this RAM should be operated at 1.5V-1.5V (does that make sense, no tolerance allowed?) Well, the setting [AUTO] yields 1.584V, the settings [NORMAL] and [1.5V] yield 1.552V, and the setting [1.4V] yields 1.45V, all measured on the PC Healt Status Page or with lm_sensors (Linux). Unfortunately there is no option for [1.45V] which I might expect to yield 1.5V, eventually. But is that 0.5V difference ok, anyway? Or is the voltage regulation of the MB faulty? Btw, I tried that with two different PSU's: same results.

Next strange thing: memtest86+ shows the memory freq, 666/1332MHz. However, sometimes after boot (with or without power cylce) there are odd values like 677/1354MHz or so, without any setup changes made. So what does that mean?

And then, can it be that some bios settings require a complete power cycle to become effective? It's because I tried various settings, which virtually did not change anything. But after a power off suddenly it did not boot at all, or showed only 2GB RAM instead of 4GB, or the like.

I would be glad if someone could give me advice, since I'm completely lost. I don't even know if I could/should return parts to the shop, because I don't know what actually cases the problems, RAM or motherboard, or something else?

Re: GA-P55 UD3 Cold boot BSOD problem

Have changed my blk frequeny to 160 in order to get the ram running at 1600 - so now it's dong everything it says it should (1600, 8-8-8-24 at 1.65 volts), I'll see how the cold boot goes tomorrow.

Re: GA-P55 UD3 Cold boot BSOD problem

Just thought I would give this post a little bump to see if anyone has some further guidance, thoughts or even funny jokes to remove some of the frustration of bsod's on cold boots :)

Following on from my previous post in this series I reinstalled W7 over the weekend and all my corruption issues with windoze files have been resolved for the time being but I am still experiencing bsod on cold boot. Not surprising as I haven't changed any voltage or timing settings in the bios at this stage, pending advice on previously posted settings.

Cheers

Re: GA-P55 UD3 Cold boot BSOD problem

Can it be that C1E "Enhanced Halt" is the culprit?

I experimented with various settings since my last post. Amongst others I set memory freq as low as 800MHz (default is 1333MHz), which still showed instabilities until I disabled C1E. Whit that the PC was stable over the weekend and passed a number stress tests and memory tests without errors.
Lets see if the next days support this suspicion, and then I'll try to gradually bring the DRAM clock to its default 1333MHz.

>>Can it be that C1E "Enhanced Halt" is the culprit?

Hi Roland,

can't confirm. C1E enabled/disabled/auto does NOT have any effect on my setup... crashes/BSODs as usual running dual channel mode with either setting.
