P5N-E SLI (anyone else getting the same problem)

djjshadow · 13 Sep 2007 at 13:51

i got a asus P5N-E SLI mobo, a Q6600 and 4 gig of ram (cpu overclocked to 2.63ghz and ram at 733).when i overclock it higher to 2.8ghz and 750mhz for example it runs stable and all tests are ok in prime 95, so thats all good, i keep the settings and turn it off for the next day, i turn it on again the next day and it doesnt get further than POST, the motherboard name comes up but thats it.it seems to be that when i turn it off and on again when overclocked over 2.63ghz it doesnt work, only works if i just restart the comp, not power down and on again. ( i dont want the only option to be that i have to keep the comp on 24/7),

if anyone can help i would appreciate very much.

I've heard the Jmicron sata controller causes cold boot issues? Try disable that and have a look at a newer bios version

hi thanks i will try that, but if i disable that wont my sata drive not work

rick827 · 13 Sep 2007 at 14:17

No, thats the e-sata controller

i see that you have the same board, and oc cpu, have you had any problems

RaiderX · 13 Sep 2007 at 14:58

are you using 2 x 2GB or 4 x 1GB for the RAM? the nvidia chipsets dont overclock well with all 4 slots filled, try taking out 2 sticks and see how high u get then

djjshadow · 13 Sep 2007 at 15:01

i got 4 x 1 gig sticks but i dont really want to sacrfice 2 gig of ram or even 1 gig seeing as my vista ultimate 64 eats up lots of ram, but yeah i will try it and let you know...

Mines the same mate, but it always starts up 2nd time round

mp260767 · 13 Sep 2007 at 18:10

set the overclock to unlinked and set to memory to its default speed.

what voltages are you using for the memory and cpu ?

WJA96 · 13 Sep 2007 at 19:06

It's either the JMicron eSATA controller or you need to run [linked][SYNC] and it will fix it.

djjshadow · 14 Sep 2007 at 09:54

i try the second time but still doesnt start, my voltages are set to auto, i will try it linked (sync mode), hopefully that will fix it.

I am the same mate. I just cant overclock on this mobo for the love of god!

Ive tried everything. Changing Voltages.... Upping them, lowering them. Setting to Auto..... Unlinked.... everything.

I too have 4 x 1Gb of Memory.

Nothing works! Ive heard this mobo is terrible with a Quad Core.... But please dont give up. I want to run at 3.0Ghz.

djjshadow · 14 Sep 2007 at 11:18

hiya, thank god im not the only one with the problem, my only safest overclock at the moment is using the AI overclock which gives me the current specs i got in my sig, have you tried the linked sync mode with fsb at 1333, which sets your ram at 667 i will try that as soon as i get home

Shep_Cobain · 14 Sep 2007 at 11:25

It does the same... if i do get to windows without locking then if i put my CPU under 90% stress it reboots. Temps are fine bout 45 under load.

djjshadow · 14 Sep 2007 at 11:39

ive set it to 2.8 and gets temps 60C full load buy using the unlinked mode but like i said when i turn it off, it dont turn on again. i want to know whats happening in the time when i turn it off and on, somethings going wrong, probs my ram, ill try just oc my cpu without ram

mp260767 · 14 Sep 2007 at 12:24

sounds like its an issue with the overclock, try upping the vcore a notch see if it helps.
