Cold boot issue

[bluezero5]

Alright, I am trying to set up a new machine, and run into a problem I haven't had before. Insights will be most welcomed.

Setup is such:

3930x on a RIVE board
OS win-7 64 bit

Problem:
Computer cannot finishing load OS during cold boot. Will ALWAYS stop at the logo. (repulicated many times)

however, if during cold boot, you pass by the BIOS, just get in, Save and exit, the system boots without any problems whatsoever. Also passes ALL stress tests, P95, SuperPi32M, IntelBurn, with no problem at all.

now this perplexes me.
what is it does a warm boot and cold boot not have in common?
why does passing the BIOS make the OS load when it otherwise won't?


experiements taking:

Normal reset start: No problem.

now COLD BOOT DOES work, when CPU multiplier is at 48. at 1.50V

so I thought, AH HA, Vcore problem.
BUT upping Vcore by 500mV (to 1.55V) to try Cold Boot: still fail.
still needs to pass by BIOS to boot, and then system totally ok.

System ALWAYS POST.
so what is it that a cold boot requires that a warm boot doesn't?

and WHY it always stop at the window LOGO screen?
any insights?

The problem with cold boot happens with multiplier is 49+, and adding Vcore doesn't seem to fix the problem...

Have you checked the memories with Memtest86+? You know, before booting into OS... it could be a DRAM voltage issue... or other memory setting problem...

Basically I think your overclock is not stable. You will have to try and tweak voltages but 4.8GHz and up is not guaranteed. How do you have your Digi+ set up your LLC etc.?

Other things this could be some driver not loading properly...SSD firmware not up to date...

Hmm interesting problem. What is the Q-code LCD poster showing during the pause?

I suspect that the system is struggling to pick up some device that you have installed. DXE int thing. But why that only happens on cold boot I do not have an answer. Most of the time that longer boot sequence (not what you are having I do not think) is when the IMC is retraining after a frequency change.

LLC medium.
180 CPU capacity

and I initially thought it is a RAM problem too.
but that won't explain why at x48, it boots up fine..

I am running out of pathway and reasons...

>What is the Q-code LCD poster showing during the pause?
what you mean there?

>.SSD firmware not up to date...
I thought so too, but how come only in cold boot?
the OS is installed in a RAID0 SSD, and I was thinking is there anything that cold boot doesn't load?
and can't think of anything..

this problem also suddenly happened too.
was fine for a few days until it happened.

my only lead now is:

There's something in Cold Boot that is not loaded unless BIOS is passed by.
and this something doesn't matter when the multiplier is x48 or lower.....

what can this be? should I persue this lead?

[HiVizMan]

There is a two digit LED poster on the board. That will give you a set of numbers/letters that correspond to the part of the POST process the system is in.

[bluezero5]

it always passes POST though.

only freezes on the windows 7 logo during OS load...

[Arne Saknussemm]

So it always gets to AA? Anything in event viewer? any Kernel power errors?

[bluezero5]

no BSOD no nothing.

always gets to window starting logo.. then loads a few secs, then freezes.

this doesn't happen if:
CPU multiplier is at x48
or
Any CPU multiplier on NON-cold boot.

[Arne Saknussemm]

Well you could still check event viewer even though there is no BSOD it might give you a clue. The only thing I can think of is memory training on cold boot. Try pressing Go button (or is it still called mem ok button) on cold boot?
