Asus P5E Deluxe and TWIN2X2048-6400C4 Crash


Recommended Posts

Hi - New rig built by my reseller, had it since 6 months.


The whole system restarts about 2-3 times a day randomly - could be during memtest on freshly booted system, while writing in WORD, while surfing the net, while paying games, etc. No CPU overheating apparently involved.


No overclock involved. All set on auto in BIOS. I have noticed on Corsair website that these sticks run (?) at 2.1V, while my BIOS won't let me go beyond 1.8V, it will reset automatically after I manually set it to 2.1V - could this be the issue?


prime95 gives me errors when I check with Blend, but not with other tests.


Memtest86+ has given me errors on occasion, but most time the whole system will just reboot.


WinXP 32bit, I have disabled the auto-reboot on error setting, but this does not change anything, and because the system will reset even when running memtest (which is not in WinXP) then I gather that this has nothing to do with windows.


Please help. What else should I check?

FYI, there is no such thing as Dual Channel memory, as this is a property of the memory controller in how it handles memory. This is why you can place memory in different slot configurations on a motherboard and it will register as single or dual channel.

Hi guys.


I sadly cannot put the RAM at anything above 1.8v???


In fact, I can enter manually the timings as 4-4-4-12, when I reach the vDRAM it lets me put in a value of say 2.0v (it says on the RAM stick 2.10v ver 6.2), then I save and exit, the system seems to shut down for 2 seconds, then it is up again but the vDRAM is back to 1.8v in the BIOS!!!


I am not sure, but could this be why my system is unstable, that the RAM is not getting enough juice?


(remember I do not overclock)

Thanks RAM GUY


In fact I finally got to put the voltage up, I brought it to 2.0v (in case this MB overvolts, I do not want to go over the indicated 2.1v).


I have tested one stick with memtest86+ and it went through flawless for 10 hours in slot 1. I will do some more testing later tonight when I get home.


Thanks for the support!

I finally got some stability, prime95 and memtest86+ without crash... it simply was that this MB was only giving 1.8v to these sticks and all I needed (dumb me!) was to manually set it to 2.0-2.1v.


Now why is it that the MB did not recognize these instructions from the sticks themselves? I thought this was programmed onto the sticks?
