The Xtreem ARGB White DDR4-4000 C15 is, without a doubt, a snappy memory kit. Fast performance doesn’t come cheap, though, especially with cherry-picked memory kits like this, so be prepared to pay for the privilege.
Great performance
Tight timings
Attractive aesthetics
Expensive
Low OC headroom
The TeamGroup T-Force Xtreem ARGB White DDR4-4000 memory kit comes to market at a time when Intel’s latest 12th Generation Alder Lake processors have prompted a shift to DDR5 memory. However, TeamGroup, like other manufacturers, continues to push the performance limits for DDR4. So even though the company is certainly no stranger to our list of best RAM, it didn’t bring us speeding-fast data rates, like DDR4-5000 or anything, this time. Instead, TeamGroup offers an optimized memory kit in the DDR4-4000 category with very attractive memory timings.
The new memory kit belongs to the Xtreem ARGB lineup; it retains the same aesthetics as the vanilla Xtreem ARGB memory modules. However, as the model name denotes, the Xtreem ARGB White features a white aluminum alloy heat spreader instead of the typical dark blue and purple theme from the standard Xtreem ARGB memory modules.
The Xtreem ARGB White measures 49mm (1.92 inches) tall. The memory module’s translucent body allows the interior addressable RGB LEDs to shine. There are two ways to control the lighting — you can opt for TeamGroup’s T-Force Blitz software or your motherboard’s software. You won’t have to worry about compatibility issues since the Xtreem ARGB White supports Asus Aura Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Light Sync, ASRock Polychrome Sync, and Biostar Vivi LED DJ.
The T-Force Xtreem ARGB White DDR4-4000 C15 memory kit consists of two 16GB memory modules with a dual-rank design. TeamGroup produced them on a 10-layer, black PCB with Samsung K4A8G085WB-BCPB (B-die) integrated circuits (ICs).
The memory modules will operate at DDR4-2400 with 16-16-16-39 timings out of the box. Once you enable XMP or set them up manually, they will hit DDR4-4000 with 15-15-15-35 timings. The required voltage for the configuration, as mentioned earlier, is 1.5V. See our PC Memory 101 feature and our How to Shop for RAM story for more on timings and frequency considerations.
The Intel system employs the Intel Core i9-10900K and Asus ROG Maximus XII Apex, which operates on the 0901 firmware. On the opposite side, the AMD system consists of the AMD Ryzen 9 5900X and the Asus ROG Crosshair VIII Dark Hero. The latter is on the 3501 firmware. Meanwhile, the MSI GeForce RTX 2080 Ti Gaming Trio is in charge of the gaming RAM benchmarks,
Overall, TeamGroup’s memory kit was the fastest in our application tests. In gaming, it was marginally slower than the G.Skill Trident Z Royal DDR4-4000 C17. However, the Xtreem ARGB White performed exceptionally well in Microsoft Office workloads, where it was over 10% faster than the slowest memory kit. It also had strong outings in the compression and decompression benchmarks, beating the single-rank memory kits.
The Xtreem ARGB White dropped to the second position in the cumulative application chart on our AMD platform. However, there wasn’t a huge difference between it and the G.Skill memory kit. The memory kit was very impressive in the y-cruncher test, where it finished the benchmark over 20% faster than the slowest memory kit.
To run at its XMP settings, the Xtreem ARGB White already pulls 1.5V, so there wasn’t a lot of headroom for overclocking without pushing over 1.6V. We opted for a more moderate 1.55V DRAM voltage to hit DDR4-4133 and only had to slightly relax the tRCD, tRP, and tRAS timings.
TeamGroup optimized the memory for 15-15-15-35 at 1.5V. Increasing the DRAM voltage to 1.55V didn’t produce any favorable results. We suspect that it would take 1.6V+ to get the memory timings further.
You get a pretty good idea of the type of performance you can expect by only looking at a memory kit’s data rate and timings. We knew the Xtreem ARGB White DDR4-4000 C15 would be one of the fastest memory kits right out the gate, and it fulfilled our expectations. But, of course, this caliber of performance doesn’t come cheap, so it may not be an enticing product for average users.
As you would expect, the Xtreem ARGB White DDR4-4000 C15 is a highly-binned memory kit. So it doesn’t surprise us that it carries a premium price tag. Unfortunately, the memory kit isn’t currently in stock, but you can find it for $335 at TeamGroup’s Amazon store (opens in new tab) when it debuts. It’s the kind of purchase that requires extra contemplation, but if it’s high-speed performance you’re after, the Xtreem ARGB White DDR4-4000 C15 is one of the better alternatives.
