Aurora R7, added RAM, slow boot issue

To everyone following this thread - turns out it may not be anything to do with the RAM at all. The engineer replaced the Motherboard the FIFTH time today and still ran into no POST black screen. So they now suspect that it's an issue with the GPU aka the GTX1080 that came with the system. They have ordered a replacement GPU. I will post an update once the new one is in. Thanks for all your help.

so you didnt test the PC as a minimum system first with NO GPU CARD using the onboard IGU.

5 motherboards  really?

learn that we always strip all PCs down if they fail, this is SOP in the business, lots of shared resources.

I does not take any engineer to do that ever. sorry

Savvy, I do appreciate the help but unfortunately I'm not able to quite follow your posts. I'm guessing you're saying that the module isn't compatible as a pair?

again

do not mix ram types, nor makers, (the intel data sheet told you not to mix SKU, that means exact Maker part numbers ) SKU means bar code stock keeping units (the sticker in the RAM do not mix those ! nor makers)

do not fail to use QUALIFIED and Certified, ram, kingston his it,  i posted the link.

do not fail to use, Certified for Haswell CPU memory, Gen4 CPU up.

why is this not clear,?  (yes some ram (in the real world ) can mix but are you going to try all RAM made for 6 months labor and shipping 2 times each way for 6 months to just discover that.?

NO YOU WILL NOT, nor will INTEL nor will DELL, see why?   (it's too much work and the products keep changing fast ) The cure as stated 1000000 times is matched certified Haswell complaint DDR.

slow posts? (lets do just that now) (*slow Power On Self Test) or P.O.S.T

this is because, the BIOS screen only has the silly moving bar. DELL POST BAR (marketing designed)

I have this great MOBO here from ACTUAL  Intel,  (D945G) that has this super great BIOS. and runs w10-64

it shows the POST codes in hex on the screen and LIVE ! as it progresses.   (00 to FF) start to end. 2digits on screen tiny.

so if the PC POST hangs mid stride,  you see a hex code that sticks there, (for RAM?) yah,nice no? real time presentations from the POST (00 to FFhex)  then boots.

the only thing DELL gives you is the BIOS LOGS. if the silly log fails to show facts you lose.

and pray for POST TEXT error live that YOU DO NOT GET.

, unless GPU is lost too. and can not do TEXT errors at the lockup delay.

but wait all good shops have a  set of POST cards, (I DO) i insert the card and see the same thing . hex.

on mine it can hang on memory , if RAM is wrong, (or BIOS not updated to support newer RAM(DDR)

the problem , is if the screen is dead no codes show up and only beeping can work, or flashing LED codes.

I'd bet most errors  of the 255 errors are not reported by dell, (up to) like good PCs can do.

as you know now it is stuck and no cue why, but is sticking for sure, (knowing where is needed by you)

the other problem is BIOS may get lost. after all if the DDR is failing and can not map the GPU card properly the POST can get lost. (stuck in loop in the POST sequences, this is YOUR DELAY)?

my last failure, got in POST code 31 loop, extended  ram failure. the only clue was my cute POST card.

I have 4 cards, PCI, PCI-e , parallel and USB. from old PCs to newer. I bet yours gets stuck in RAM tests.

My z270 new PC even works with this card, in the PCI-e slot.

and this  PC fails to beep for RAM when RAM is in fact  failing. (we can only guess., lacking a CODE in hex.)

maybe the 25th  newer version of BIOS can be smarter and tell you what's up. (sarc off)

i guess ePSA is useless after all I bet it runs POST> P.O.S.T(pun intended but serious)

after all the ePSA will only test devices,  what POST finds, and can be wrong.(the PnP list  wrong)

end ideas by me,

google ram fails and read,  it really is the endless story..... for upgraders....

the problem is not letting real; PC repair shop fix your PC. (hands on repairs are x10 better the text box  IDEAS, no?)

they have the tools and spare parts. (1 of 4 parts are bad (PSU, MOBO or GPU card) no IGPU tests done. sigh.

not doing full strip down test,  is your/their? problem, we  know that now. (the problem is RAM or GPU card)

I wonder does the stripped down PC run ok with 32GB of ram? IDK !

here is MOBO focused strip test, just to prove the card is good or bad. just  it.

here are the glory days of full post code reporting PCs. (huge list of useful codes, that you can't see)
