P55A-UD4 startup "BSD" ~ why?

You are welcome and please let us know how you get on with it.

Hi

Just to update.  As mentioned last night I was running at vCore 1.2v but concerned over the 95W being exceeded as the Max.

Well this evening I started by dropping the vCore to 1.1v and got the BSD ~ for the record I can npw tell if it is going to happen at Boot because it takes an age to POST beep.

Upped the vCore to 1.11875 and again very slow POST and BSD so raised it to 1.125v and it booted OK, whether this was because it had warmed up a little by then is moot?

So screen grab of HW Monitor at this 1.125v vCore


The CPU fan has increased by approx 50rpm and is audibly a tad noisier the Core#0 temp at idle is better but the Max Processor Power at 108.33W does worry me a bit so is it anything to be concerned about???

As always the proof will be in the eating so will have to see if it boots AOK tomorrow after being shutdown during the day for something like 8 hours.

Any insight ref the wattage Max of 108.33 would be welcome or any additional insight with the new screengrab???

Edit ~ next on the shopping list is that fan controller

The thing is a s a general rule it is not the wattage that is important but how you deal with the heat it produces. If you can maintain a cool processor then you shouldn't have any problems. So keep an eye on your temperatures.

Makes sense but what is the threshold temp for an i5 760 that I need to be aware of and as mentioned I ma currently using the Mobo CPU temp sensor and CPU fan plugged into the mobo.

Wracks brains for the name of the Fan Controller with the nice LCD face you suggested a good while back??? If you use that and plug the CPU fan into it where do you place the sensor head to control that fan???

Is there a HW monitor program with low resource footprint that has a logging function and alarm warnings to aid such monitoring of the risk of running too hot for too long??? Possibly one that allows for controlled shutdown if the PC is left unattended when an overtemp occurs???

Lamptron Touch Fan Controller I think is the one you are thinking of. I have one installed and wouldn't be without it now.

As to where to site a CPU sensor It would depend on your heatsink. I would try and get it as close to the CPU as possible with a little bit of thermal paste also to aid conductivity of the heat. You could even use thermal epoxy to glue it in position. The sensors are detachable from the controller so no problem if you need to dismantle it.

The BIOS has a CPU cut out if it overheats anyway.

Thanks for the reminder & pointer re controller ~ the BIOS overheat cutout is that default set, must go see what it is set to???

I am using the Intel stock HSF so would need to eyeball as to the best place to 'stick' a Lamptron sensor???

Any thoughts about a suitable HW monitor program???

Talking of temps ~ just what is the max for the i5 760???

[Dark Mantis]

The i5 760 has a TCASE of 72.7°C

Well as the CPUID HW monitor list the max 108.33W with the Core #0 max temp of 46 degrees it is positively arctic when compared to the TCASE figure.......er just what is TCASE??? Is that the auto cutout figure you mentioned?

Update I got the BSD this morning with vCore 1.125 so have upped it a little (there were a couple of otghers offered in between) to 1.15v   ..........I was having the BSD less often when on "auto" :lol:  Seems that the only way to stop such BSDs is to turn off the PSU to allow the motherborad to discharge, certainly odd to me???   A reboot when 'hot' seems fine it is just when it has been powered down for some hours and is/was as mentioned completely random as to whether it will happen!

Just some random thoughts ~ though vCore error code is shown on the BSD could it be the memory self test during POST that has an effect ~ I note that the inital screen I see after the POST beep already shows total RAM but on my old 845e chipset build the screen came up and the RAM check counted through ~ could the be a graphic card/driver issue.   As I say just random thoughts

[Dark Mantis]

TCASE is the external temperature of the package and if the Tcase is 70C the core tempertures would be around 85-90C

Well you never know with computers as just when you think you have it taped it will surprise you. It is al;ways worth checking everything you can think of if you have a problem and it doesn't seem to be reacting to your attempts to rectify it as it should. Try running Memtest86+ on the RAM. It takes time but can be beneficial.

Memtest86+ V4.20 Beta 13

.Bin :http://www.memtest.org/download/beta/420b13/mt420b13.bin
.Iso :http://armstrongcomputer.ca/mt420b13-jasonacs.iso

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 loops and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.

If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Right this is still so darned curious:-

I seem to be getting the same BSD with the set vCore code whatever I do i.e. I thought I had it cracked with vCore 1.15v the PC booted fine early evening......shudown to go out for a few hours.......booted a few mins ago and BSD!   In principal I was seeing the BSD less often with the vCore set to "Auto" in the BIOS

I have realised that if I listen very carefully during the time before the belated POST beep there is a very brief and quite quiet click ~ reminds of the sort of noise micro relays used to make when they latched.....no idea what it could be but now I know to listen I can hear it during the delayed POST period.  When it POSTs normally I cannot hear the same 'click'.

As mentioned before (so far) the way to overcome the BSD happening more than once in succession is to power cycle the PSU.....for the record I get the whole set of Phase LEDs lit on the next 'cold boot'.  Methinks I may reset the vCore to "Auto" and do a cold boot everytime over the next many days and see whether any more BSDs happen.........on the surmise that all remains AOK doing it this way then the question still remains as to what has/is causing the error???

Oh, for the record I did run a strees test and all was on the face of it fine with no instability showing up.  CPU fan ran up to 2400rpm and all 4 cores maxed out at 66 to 67 degrees

Ref HPET

Would changing this to 64 bit mode from the default of 32 bit have any effect/improvement??? i.e. I am wondering as this is maybe a "timings related question/issue" perhaps a HPET change would help???

FWIW and in case it has any bearing ~ I have installed both 64 bit programs and others in 32 bit compatibility mode.

TIA once again

[Dark Mantis]

The HPET mode should be set to 64 bit if you are using a 64 bit OS. It may well run fine on a 32 setting but it is just added performance.

Can you try a different PSU ?

I ask because this "click" sounds a bit weird to me.

Hi DM

OK I will set the HPET to 64 bit mode.................though I am surmisng that programs installed under 32 bit compatibility mode will be fine???

Sadly no other PSU ~ I dumped my old non SATA plugs one which would not have helped anyway   I agree the click sounds odd but it has dawned on me that though is is so brief and soft a sound I could not tell where it was coming from it coul be the powered speakers???  Just have to turn them off for the next few occassions.

But as mentioned I have now set the vCore back to auto and last night turned off the PSU switch.  What I will do to relisten for 'click' is leave the power supply "on" but turn the speakers off.  That way if/when I get the BSD situation again the speakers should out of the equation???

[Dark Mantis]

Yes I would agree. Probably best to disconnect the speakers totally.

HPET 64 bit mode should work fine even with programs running in 32 bit compatibility mode.
