kokito_malik Posted August 17, 2009 Share Posted August 17, 2009 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? Link to comment Share on other sites More sharing options...
Wired Posted August 17, 2009 Share Posted August 17, 2009 See if it's stable when setting the memory voltage to 2.1 when using one stick. Link to comment Share on other sites More sharing options...
kokito_malik Posted August 18, 2009 Author Share Posted August 18, 2009 just a quick update... I have removed one stick and prime95 now works without errors... what gives? No compatibility for dual channel? I will try more tests and update you guys. Link to comment Share on other sites More sharing options...
Wired Posted August 18, 2009 Share Posted August 18, 2009 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. Link to comment Share on other sites More sharing options...
kokito_malik Posted August 18, 2009 Author Share Posted August 18, 2009 Thanks Wired for the info, in fact what I meant by "No compatibility for dual channel?" was whether this MB has problems using these memory modules in dual channel... I will do more tests tonight when I get home and report. TIA Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 18, 2009 Corsair Employees Share Posted August 18, 2009 Test each of the modules one at a time to be sure one is not failing and if they both pass then I would try moving them to the other two slots and test the system again.

kokito_malik Posted August 19, 2009 Author Share Posted August 19, 2009 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) TIA Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 19, 2009 Corsair Employees Share Posted August 19, 2009 I would check for the latest BIOS version and maybe ask the MB maker about that voltage setting, and have you tried the modules one at a time to be sure one is not failing?

kokito_malik Posted August 20, 2009 Author Share Posted August 20, 2009 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!

Corsair Employees RAM GUY Posted August 20, 2009 Corsair Employees Share Posted August 20, 2009 NP Please do let us know what happens. Link to comment Share on other sites More sharing options...
kokito_malik Posted August 21, 2009 Author Share Posted August 21, 2009 HURRAY! 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? THANK YOU THANK YOU THANK YOU!

Corsair Employees RAM GUY Posted August 21, 2009 Corsair Employees Share Posted August 21, 2009 You have to set the tested settings manually only with SLI ready memory support would it set all of the settings for you. Link to comment Share on other sites More sharing options...
