TWIN3X2048-1333C9DHX v3.1 on P5E3 motherboard freezes in Vista


Recommended Posts



Not sure if new memory is faulty or ASUS P5E3 with BIOS 1404 motherboard is incompatible with the new memory.


I already had Corsair TWIN3X2048-1333C9DHX v1.1 on my motherboard for over a year running on default auto settings. Never had a problem.


Decided to buy another pair a few weeks ago. The only difference is that they are version v3.1. Put in all four sticks on the motherboard. Won't boot up in Vista. Had to adjust DRAM and NB settings in BIOS. Got it running, but still freezes up in Vista. So I tested the memory in pairs in different slots of the motherboard.


What I did was:


Test 1:


Remove existing v1.1 2 x 1GB memory from orange slots (been in orange P5E3 slots since middle of 2008 no problems at all).


Put in recently purchased v3.1 2 x 1GB memory in orange slots only and ran with default auto settings.


Windows Vista froze within 45 mins to 1.5 hours


Test 2:


Put in recently purchased v3.1 2 x 1GB memory in black slots only.


Windows Vista froze within 45 mins to 1.5 hours


Test 3:


Remove recently purchased v3.1 2 x 1GB memory from black slots.


Return existing v1.1 2 x 1GB memory to black slots this time to test the slots.


No freezes at all.


So the motherboard RAM slots are fine and everything points to the V3.1 memory.


Ok back to the recently purchased memory revision v3.1. I ran memtest 86+ v2.11 and it passed with 0 errors, but that does not explain why it freezes in Vista using v3.1 revision memory. My PC has no problems at all since I last year and still has no problems except for the recently purchased memory freezing up in Vista.


Not sure if there is a problem with running Corsair TWIN3X2048-1333C9DHX v3.1 on P5E3 motherboard? Revision v1.1 works fine in all slots and has no problems. Not sure if memory is faulty because memtest found 0 errors in 1st pass. I only ran 1 pass.


At the time of the motherboard purchase that brand and model of memory was in the QVL in 2008 so that is why I bought it.


I came here from an ASUS forum seeking more advice on memory compatibility:




Can you advise?

With 4 modules I would suggest setting the memory frequency at DDR1066 and set the memory Voltage to 1.7-1.90 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.
