Ballistix Sport LT 32GB DDR4-2666 SODIMM on ASRock X299E-ITX/AC


Overclocking is never guaranteed so the presented results may vary from results on other memory kits. I am not recommending overclocking if you do not know what are you doing. High voltages may damage hardware and it will not be covered by warranty.

I won’t hide I wasn’t expecting to set much above DDR4-3200 knowing how most Micron based memory kits are overclocking. Each try was a surprise so playing with this memory was simply a lot of fun.

First step was DDR4-2666 at tight timings. I couldn’t make it run at less than CL15-15-15 so hard to call it great result so I’ve moved to higher frequency.

DDR4-3000 CL17 so also nothing special if we compare it to standard size DIMM.

DDR4-3200 CL18 and I thought it will be end of the adventure …

but after relaxing timings some more I’ve seen DDR4-3400 CL18

Why not to try DDR4-3600 ? …

DDR4-3733 already required CL19 and DDR4-3866 couldn’t boot below CL20 so I skipped both and went for the crown ( not expecting it will even boot ).

Big surprise! DDR4-2666 SODIMM memory overclocked to DDR4-4000 at 1.35V!

Even at sub-timings set to auto and quite relaxed main timings we can see 100GB/s read bandwidth in AIDA64.

DDR4-4100 was too much and one of the memory modules was not working in Windows while two or three could boot up to DDR4-4150.

At the end DDR4-4000 after some timing tweaking and magical 110GB/s read bandwidth! What’s even more impressing is that at these settings test PC runs 24/7 for nearly two weeks!

Once again, overclocking potential of the Ballistix Sport LT DDR4-2666 SODIMM memory exceded all my expectations. It wouldn’t be possible without ASRock X299E-ITX/AC which is simply amazing little motherboard.
