Inconsistent boot error z97-a

[Freddyfish775]

Hi,

 

i upgraded to a z97-a + i5 4690k and use a scythe mugen max cooler.

I used to get a boot error about the ram (the ram LED was bright red indicating ram issue) but the 

mem-ok! button fixed this issue.

 

However, when the pc has been turned off for an extensive period of time (say 8+ hrs) it sometimes doesnt boot and the cpu led is bright red.and there is no post. If i reset a couple of times it sometimes boots anyway.

 

I have not overclocked on this system and ive disabled all overclocking in the bios. The temperatures after 5 hrs of battlefield hardline were fine (44°C) and the clockspeed is at its max turbo speed so I dont think the cpu is faulty?

 

Any thoughts on what could cause this issue (which is not always there)?

Are you sure you plugged the RAM into the correct slots?  I know with my Asus motherboard, they are not supposed to be next to eachother when in dual channel mode.

 

1 / 3 / 2 / 4

 

For dual channel, you are supposed to place the RAM in slots 1 and 2 for example.  This is just a guess, chances are you have it done right, just a guess.

they are in ram slot 2 and 4 as stated in the manual 1-8 (dimm a2 and b2), Have they changed this?

You need to quote or "@" someone to let them know you have replied.

 

If you followed the directions as stated in the manual, then you have them placed correctly.  You could run some programs like Memtest or the sort to see if the memory is bad.  I have no experience with these such programs though.

Sorry about that!

 

I have now ran prime95 for four hours and the max cpu temperature is 60 °C. At the same time ive ran furmark to fully stress my system (prime95 has run blend and small fft's). Is it safe to assume none of my hardware is faulty and its probably just a combination error?

 

Is there anything unhealthy about having to reset your system twice to three times for a first time boot of the day?

Its not ideal, I don't know if it is detrimental though.

 

Side note:  Never, ever run furmark/kombustor.  Use unigine Heaven/Valley or a built-in game benchmark utility.  Furmark has the potential to brick your GPU.  Its rare, but it happens.

After looking more into this issue i found it happened a lot with the z87-a aswell and apparantly it is related tothe power supply: http://rog.asus.com/forum/showthread.php?38894-asus-z87-a-cold-boot-hangs-red-cpu-light/page6 .

 

I am using an earthwatts 650 atm, and i believe it was certified for haswell. Dont suppose i could test this without buying a different power supply?
