Crashes and BSOD with EP45-UD3P

Re: Crashes and BSOD with EP45-UD3P

Please raise your v core up one notch at a time. Are you sure your VID is not more like 1.25000v?

Re: Crashes and BSOD with EP45-UD3P

I am running the template that Conner made. My temperature cores are way down now.

Re: Crashes and BSOD with EP45-UD3P

You realise that 100c core temps are the absolute maximum allowed temperatures. At that point the processor throttles or even shut down completely. Runing temps of over 80c for long may shortenn the life of your CPU.
Temps should be kept below 70c for Prime95.

Chike that may have been a large part of the problem don't you think?

Re: Crashes and BSOD with EP45-UD3P

Umm... I don't know where the VID on CPU-Z is but I used Core Temp. If the VID = Core Voltage on CPU-Z then its around 1.136-1.152V but on Core Temp it says 1.2125V. This is all while running LinX after turning up the V-Core up a notch.

Failed IBT around 65 Seconds
and LinX at 2 minutes 9 seconds.

CPU Enhanced Halt (C1E)..............: [Disable]
CPU EIST Function....................: [Disable]

Disable those two and then see what vid reads.

Edit: When you first load optimized defaults what did the bios say the vcore was?

CPU Vcore….………........1.25000v......: Auto
................................^^^^^^ that number

Re: Crashes and BSOD with EP45-UD3P

Um... on Core Temp it reads 1.2125V and on CPU-Z the Core Voltage is 1.168-1.184
but the Core Voltage drops to 1.136 to 1.168 and the VID doesnt move during LinX.

It was all - Auto.

Re: Crashes and BSOD with EP45-UD3P

If you save a text dump in CPU-Z the VID is not far below.
VID is stock vcore, what you see in BIOS as default. The motherboard set this value but there is a vdrop so the actual value on idle is lower. Than at load there's vdroop which lower it even more, it's all part of normal operation nothing to worry about.
0.1v vdrop+vdroop is not an exception.

Re: Crashes and BSOD with EP45-UD3P

CPU Vcore is said to be 1.21250V. But I turned it up to 1.21875V because u said to turn it up a notch.


Also max vid on Cpu-Z is 1.213

[Conners]

Re: Crashes and BSOD with EP45-UD3P

Ok do this start CPUZ and go to the about tab and click on Save Report (.TXT) Then open the report and scroll down to where it says Max VID 1.250 V. Replace 1.250V with what your says. Like chike says. Also whatever that number is put it in your bios instead of auto (or wharever # you had) on vcore. Then test... let us know what happens...

Read my edit.

Re: Crashes and BSOD with EP45-UD3P

Ok read edit put that number in your bios...if test fails raise one or two notches. If that fails raise up MCH core one notch. But it should work on the stock speeds.

Re: Crashes and BSOD with EP45-UD3P

failed at 3minutes 33s for LinX
and 65 seconds for IBT

Re: Crashes and BSOD with EP45-UD3P

Could you run P95 small FFT's and see what you get. Also you need to check Round off checking under advanced tab if you didn't know.

Please post your current bios also.

Re: Crashes and BSOD with EP45-UD3P

Also lifted from a thread of mine on Prime 95 tests and what they mean by Psycho101

Small FFT
This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
Not enough vCore
Possibly low CPU Termination (VTT)
Possibly low/high CPU ref
Possibly low PLL (clock generator) voltage

Large FFT
This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
Not enough vDIMM (RAM voltage)
Not enough (and rarely too much) MCH core voltage
Incorrect MCH ref voltage
Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
Only fails because of processor when vCore is waaaaaay too low!

Blend
This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.

Ok I gotta hit the sack work comes early for me. G/L
