jimmystol Posted July 11, 2009 Share Posted July 11, 2009 hello, i can only get three sticks of my memory to run . on insertion of the forth, my system will not post. checked all memories individually and in different dimms with memtest, all passed. gigabyte tech support reproduced my system and said they ran same memories without problem and that it must be a single motherboard problem. it was rma'd and returned but i still have the same problem. now they suggest it must be a memory problem. can memories pass in memtest and still be goosed? i am not an overclocker and have all settings on auto as i am not confident enough (or knowledgable enough) to change anything. thanks in advance Jimmystol Link to comment Share on other sites More sharing options...
Wired Posted July 11, 2009 Share Posted July 11, 2009 What version is each pair? Have you tried lowering the speed a notch to lessen the stress on your memory controller? What voltage are you running the memory at? Link to comment Share on other sites More sharing options...
jimmystol Posted July 11, 2009 Author Share Posted July 11, 2009 both pairs same version, bought same time same supplier. all voltages and settings are as stock, i haven't messed with anything. gigabyte tech support said they ran all without problem. if there is something i can try i will be very glad to try, but you will have to walk me through it as i am not over familiar with tweaking.

Wired Posted July 11, 2009 Share Posted July 11, 2009 Run the memory at the correct voltage. It'll either be 2.1v or 2.2v. The memory label will tell you. Link to comment Share on other sites More sharing options...
jimmystol Posted July 11, 2009 Author Share Posted July 11, 2009 changed voltage to 2.1v as on label but still won't post on introduction of a fourth module. also tried 2.2v with same result. auto sets ram to 1.8v. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 13, 2009 Corsair Employees Share Posted July 13, 2009 I did not see above the Corsair memory part # or possibly missed it. Please list it so I can better guide you with running 4 sticks (2 sets). Thanks! Link to comment Share on other sites More sharing options...
Wired Posted July 13, 2009 Share Posted July 13, 2009 It's in the dropdown. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 13, 2009 Corsair Employees Share Posted July 13, 2009 Try these settings below: SLI Ready: Disabled (this setting has nothing to do with your graphics SLI configuration, don't get confused) Memory frequency: 800Mhz Memory Voltage: 2.1v TCL: 5 TRCD: 5 TRP: 5 TRAS: 15 Command Per Clock: 2T TRC: 28 NB Core Voltage: 1.4v Link to comment Share on other sites More sharing options...
jimmystol Posted July 14, 2009 Author Share Posted July 14, 2009 I've tried above settings, I don't have the SLI option in my bios and can't find TRC either, however found TRFC with a value of 68 and changed that to 28 without any joy. MB just gives me a series of 23 beeps resets then repeats after fourth memory insertion. i can remove any 1 memory and system will boot. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 15, 2009 Corsair Employees Share Posted July 15, 2009 Do you have the latest bios? If you do try older bios versions and see if this fixes this issue. Link to comment Share on other sites More sharing options...
jimmystol Posted July 15, 2009 Author Share Posted July 15, 2009 that was one of the first things i tried. when MB was returned, it again was flashed with E1 bios i thought maybe this was how gigabyte had gotten it to run without issue but apparently not. it is now again flashed with E2 bios.

Corsair Employees RAM GUY Posted July 16, 2009 Corsair Employees Share Posted July 16, 2009 There will be a lot more stresses on the memory controller on the motherboard when all memory slots are filled; to compensate for these stresses, memory controller will need to run these modules at a slower speed.
