I get errors when adding additional ram via memtest 86. Help!!

7,446 776 November 24, 2021 at 01:20 PM
I had two sticks of corsair vengeance lpx ddr4 3000 15cl ram. I bought two more sticks off of Ebay to bring my total ram from 16gb to 32gb. I run Memtest 86 on the 4 sticks, and I get errors. I test each set of ram separately, no errors. Wtf is going on here? I have no idea what's going on, and it's driving me nuts. I have the UEFI settings set to default, besides the xmp profile. I upped the voltage from the default xmp 1.35v, to 1.40v, and still no luck on the combined 4 sticks. Do I increase the voltage to 1.45v? Do I increase the voltage on the SOC? I'm kind of worried about doing something dumb, and it takes a long time to run these tests. Help!!

Asrock b450m Pro4 motherboard on the latest bios, Ryzen r5 5600x, and 4 sticks of Corsair Vengeance 3000mhz cl15 ddr4 ram (8gbx4).

Have you tried running them at default settings without applying XMP? I have issues with crashes on my ASRock X570 Extreme4 when running my Crucial Ballistix with the XMP enabled. Only way I could stabilize the system was to run at default settings for memory, 2400mhz, even though memory is rated for 3200 w/XMP. Memtest86 doesn't detect any errors on my memory.

I would, but I need the memory to run at xmp speeds, my r5 5600x requires fast memory, with low timings. It's like I said, if I test the two sets of ram separately, I get no errors. However, if I use all 4 sticks together, sometimes I get errors in memtest. I think this is fixable. I manually set the SOC voltage to 1.15, and I set the ram voltage to 1.45v. Wish me luck!!
