[SOLVED] System only works with 2 of 4 memory sticks installed.

[alan92rttt]

I recently upgraded my main desktop and am having a weird issue. If I have all 4 stick or memory installed the system will crash when playing a game (Doom 2016, Rage, Arkham Knight, Grid, Forza 4 Stra Trek Online.) If I have two installed it works fine. WHich 2 does not matter. being in a1,b1 or a2,b2 does not matter. Bios and drivers fully updated.

Any suggestions?

Were your memory sticks sold in the same package or did they come separate?

If sold all in one then you have a compatibility issue most likely motherboard. Check the QVL for your memory stick model numbers.

If they came in separate packages then it could be the two sets are not compatible together or the above mentioned issue.

Hi Alan and Welcome to the Forum

The kit you have listed is a (2x8) SKU 226316 .

You indicate your using 4 DDIMMs so you are mixing RAM kits and that is not a good idea. Even RAM with exactly the same specs can mismatch and they may boot however issues usually happen like unexpected reboots or shutdowns.

Best is to have a single binned kit that are matched at the time of manufacture and are listed on the MB QVL. That way you know they are tested and known to work.
Return what you have and sell the others or keep them for spares.

Really, I've never had an issue mixing pairs. Learn new things every day.

DDR4 is much less tolerant now with frequency OC especially with Ryzen processors.

I played with some settings and found that raising the ram voltage from 1.35 to 1.4 seems to fix the issue.

Is there a downside to this?

Best is to keep Voltage at manufacturers recommended settings however .05V to help stability is OK. Remember more volts more heat so always check temps when raising voltage for longevity.

Increased voltage did not help long term.

Gave up returned the 4 sticks I had and got 2 16gb gskill sticks and all seems good.

Thanks all.
