Here's why we added it, and how to select it on Gigabyte, ASUS, MSI and ASRock boards. - Author: Wootware Editorial Team - Tags: KingBank, DDR5, amd ryzen We now flash 11 of our KingBank DDR5 kits with a second memory profile before they ship. We call them **Wootware Lab Enhanced**. The factory profile is still on every kit for Intel systems. The new one is a DDR5-6000 low-latency profile for AMD Ryzen, which is faster on AM5 than the kit's higher-rated speed. If you've scanned the card from your memory box, the short version is below. Brand-by-brand BIOS steps follow further down. ## Which profile should you use? AMD Ryzen 7000 / 9000 (AM5) Enable EXPO, then choose Profile 2 DDR5-6000, 28-36-36-32, 1.40V. Your BIOS lists it as **EXPO 2** or **Profile 2**. KRXB 32GB DDR5-6400 kit only: Profile 2 is DDR5-6000 30-36-36-96. Intel Core Ultra (LGA1851) Enable XMP (Profile 1) This is the kit's factory profile. Profile 2 is stored as AMD EXPO only, so Intel boards don't see it. Update your motherboard BIOS before you start. Then jump to your board: - [Gigabyte](#gigabyte) - [ASUS](#asus) - [MSI](#msi) - [ASRock](#asrock) - [Intel boards](#intel-boards) - [Check it worked](#check-it-worked) - [Troubleshooting](#troubleshooting) ## Why we added a second profile Several of the KingBank kits we stock are rated for DDR5-8000\. That rating suits Intel. On our Core Ultra 7 270K Plus test bench, the 8000 XMP profile was the fastest setting in every test we ran. AMD Ryzen works differently. On AM5, the memory controller clock (UCLK) runs at the same speed as the memory clock up to DDR5-6000\. Above that, the board drops the controller to half speed, a 1:2 ratio. At DDR5-8000 the memory itself runs faster, but the controller falls from 3,000 MHz to 2,000 MHz, which adds latency. That's why [DDR5-6000 is widely treated as the sweet spot](https://www.techpowerup.com/review/ddr5-memory-performance-scaling-with-amd-zen-5/?ref=blog.wootware.co.za) for Ryzen 7000 and 9000, and why tighter timings at 6000 matter more than a bigger number on the box. Some AM5 boards can't train an 8000 kit at its rated speed at all. In our testing, the 48GB 8000 kits dropped to safe mode at 8000 on ASUS TUF B850 boards. On the ASUS TUF X870-Plus (BIOS 1805), one kit dropped to safe mode and the other booted at 8000 but failed MemTest86\. A Gigabyte X870 Gaming X WiFi7 ran both at 8000\. On boards like those ASUS models, Profile 2 is the setting that works. The usual alternative is a second, AMD-specific kit. Kits certified for AMD's new ultra-low-latency standard at similar timings are expensive: LTT Labs [quoted US$1,350](https://www.lttlabs.com/articles/2026/09/04/amd-expo-ultra-low-latency-memory?ref=blog.wootware.co.za) for a 32GB DDR5-6000 CL28-36-36-31 kit in September. Rather than stock separate AMD and Intel versions, we put both profiles on one kit. ### AMD Ultra Low Latency, briefly In June, AMD added Ultra Low Latency (ULL) to its EXPO memory standard, as part of EXPO 1.2 and the AGESA 1.3.0.1 BIOS updates. A ULL profile stays at DDR5-6000 but tightens the timings, especially tRAS and the sub-timings behind it. AMD and [Gigabyte](https://www.gigabyte.com/press/news/2414?ref=blog.wootware.co.za) say this cuts memory latency by 5 to 7 ns compared with a standard EXPO 6000 profile. AMD's [EXPO page](https://www.amd.com/en/products/processors/technologies/expo.html?ref=blog.wootware.co.za) now lists Ultra Low Latency support, and AMD claimed up to 4% higher average FPS than a standard EXPO profile in its own testing, as [LTT Labs reported](https://www.lttlabs.com/articles/2026/09/04/amd-expo-ultra-low-latency-memory?ref=blog.wootware.co.za). Profile 2 on our kits uses ULL-style timings: 28-36-36-32, with tRC 68 and tWR 48, at 1.40V. Our kits aren't AMD ULL-certified. The profile is our own, built and validated on our test benches. ## Why 6000 beats 8000 on Ryzen: our numbers We tested one KingBank KFXW 48GB kit on both profiles in a Ryzen 7 9800X3D system we built, with a Gigabyte B850M Gaming X WiFi6E board and a Radeon RX 9070 XT. Each profile ran three times. Profile 2 used the same 6000 28-36-36-32 timings that now ship on the kits. ![Chart: Profile 2 at DDR5-6000 is 7.1 to 7.3 percent faster in AIDA64 bandwidth, 4.3 percent faster in 7-Zip and has 4.7 ns lower latency than the factory DDR5-8000 profile on a Ryzen 7 9800X3D](https://storage.ghost.io/c/28/05/28056077-a219-4a38-83e0-2a813ffe2c33/content/images/2026/11/kingbank-lab-profile2-vs-8000-9800x3d-v4.png) Profile 2 against the factory DDR5-8000 profile on the same kit. The controller runs at 3,000 MHz on Profile 2 and 2,000 MHz at 8000. - **Memory bandwidth:** Profile 2 was 7.1% to 7.3% faster in AIDA64 read, write and copy. - **Latency:** 71.1 ns on Profile 2, against 75.8 ns at 8000. - **7-Zip:** 4.3% higher total rating on Profile 2. - **Stability:** Profile 2 passed a one-hour OCCT memory test with no errors. We didn't run the same test at 8000 on this system. - **Games:** Cyberpunk 2077 tied, because the graphics card was the limit at the settings we used. The CS2 runs contradicted every other result, which points to a problem with those captures rather than the memory, so we've left them out. ![Ryzen 7 9800X3D PC build with a white KingBank DDR5 kit installed next to an illuminated CPU cooler](https://storage.ghost.io/c/28/05/28056077-a219-4a38-83e0-2a813ffe2c33/content/images/2026/11/kingbank-lab-enhanced-9800x3d-build-v1.webp) The Ryzen 7 9800X3D system we used for this comparison, with the KingBank kit beside the CPU cooler. Our [August comparison](https://blog.wootware.co.za/kingbank-ddr5-6000-vs-8000-amd-intel-tested/) on a Ryzen 9 9900X with an RTX 5090 pointed the same way. A DDR5-6000 CL28 setting was 8.3% faster than the kit's 8000 CL36 profile in CS2 average FPS and 8.4% faster in Cyberpunk 2077, with 1% lows up to 9.5% higher. That test used a manually entered 6000 CL28 setting on the 32GB KRRW kit, not today's flashed Profile 2, so treat it as supporting evidence. On Intel the result flips. On our Core Ultra 7 270K Plus and Z890 bench, the 8000 XMP profile beat 6000 CL28 in every test, including 10.4% in 7-Zip and 6.4% in Cyberpunk 2077 average FPS. That's why Intel users should stay on Profile 1. ## What we changed on each kit Every Lab Enhanced kit keeps KingBank's factory profile as Profile 1 and gets ours as Profile 2\. On some kits we also fixed the factory data: - **Refresh timings on the 48GB and 96GB kits.** These use 24Gb memory chips, but their SPD stored refresh timings (tRFC2 and tRFCsb) of 160 and 130 ns. The JEDEC minimum for 24Gb chips is 220 and 190 ns. Recent AM5 BIOS updates added a "Mixed" refresh mode as a Rowhammer mitigation ([AMD-SB-7048](https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7048.html?ref=blog.wootware.co.za)), and some boards now use it by default. Mixed mode uses exactly those two timings, so on several ASUS and ASRock AM5 boards the 96GB kits wouldn't boot at all. We set them to the JEDEC values, and the kits now boot at default settings. - **Empty EXPO data.** On some batches the factory EXPO profile was blank.

Refresh timings are 295/220/190 ns on both profiles. ## How we flash and test - **A master profile per kit.** Our technical team built and stress-tested a master profile for each kit model. - **Batch testing.** Each kit is flashed with its model's master and boot-checked on both profiles. We run MemTest86 on both profiles for sample units from each batch. - **Resealed.** We open each box to flash it, then reseal it with a Wootware seal. Finished kits get a Lab Enhanced sticker on the box and a setup card inside, with a QR code that links to this guide. ## How to select Profile 2 in your BIOS ### Before you start 1. **Update your BIOS.** We tested Profile 2 on recent BIOS versions (ASUS 1805, Gigabyte F13c). Older BIOS versions may not show it correctly. 2. **Use the right slots.** With two sticks, use the slots your motherboard manual recommends, usually A2 and B2. 3. **Give the first boot time.** The board trains the memory on first boot, and the screen can stay black while it does. A 96GB kit can take up to 10 minutes. Don't switch off during training. ### Gigabyte 1. Press **Del** while the PC starts. If you see Easy Mode, press **F2** for Advanced Mode. 2. Open the Tweaker tab. 3. Set XMP/EXPO Profile to **EXPO 2**. The line below it should read DDR5-6000 28-36-36-32-1.400V. 4. Press **F10** to save and restart. ### ASUS 1. Press **Del** while the PC starts. If you see EZ Mode, press **F7** for Advanced Mode. 2. Open the Ai Tweaker tab (Extreme Tweaker on ROG boards). 3. Set Ai Overclock Tuner to **EXPO II**. On ASUS boards, "I" and "II" control how much of the profile loads, not which profile. EXPO I loads only the main timings and lets the board pick the rest, which skips the low-latency sub-timings. 4. In the profile list that appears below it, choose Profile 2: **DDR5-6000 28-36-36-32 1.40V**. 5. Press **F10** to save and restart. ### MSI 1. Press **Del** while the PC starts. If you see EZ Mode, press **F7** for Advanced Mode. 2. Open the OC menu. 3. Set EXPO to **Profile 2**, the DDR5-6000 28-36-36-32 entry. 4. Press **F10** to save and restart. ### ASRock 1. Press **Del** while the PC starts. If you see Easy Mode, press **F6** for Advanced Mode. 2. Open OC Tweaker, then DRAM Profile Configuration. 3. Set DRAM Profile Setting to the EXPO entry that reads **6000 28-36-36-32 1.40V**. 4. Press **F10** to save and restart. ### Intel boards Use the factory profile. Profile 2 is AMD EXPO only. - **ASUS:** Ai Tweaker \> Ai Overclock Tuner \> **XMP I**. - **Gigabyte:** Tweaker \> Extreme Memory Profile (X.M.P.) \> **Profile 1**. - **MSI:** OC \> Extreme Memory Profile (XMP) \> **Profile 1**. - **ASRock:** OC Tweaker \> Load XMP Setting \> the **XMP** profile. On the ASUS TUF Gaming B860-Plus WiFi, the 48GB 8000 kits won't train at 8000\. Enable XMP, then set the memory frequency to DDR5-7200. ## Check that Profile 2 is running 1. In Windows, open [CPU-Z](https://www.cpuid.com/softwares/cpu-z.html?ref=blog.wootware.co.za) (Memory tab) or [ZenTimings](https://github.com/irusanov/ZenTimings?ref=blog.wootware.co.za). 2. Check for a DRAM frequency of about 3,000 MHz (CPU-Z shows half the DDR5-6000 rate) and timings of 28-36-36-32. 3. On Ryzen, ZenTimings should show UCLK at 3,000 MHz, the same as MCLK. If UCLK is half of MCLK, you're on the 8000 profile. 4. Run a memory test such as MemTest86 or the OCCT memory test before you rely on the system for work. **No "ULL" label? That's normal.** Boards and CPU-Z only show the ULL label when the ULL profile is Profile 1\. On our kits it's Profile 2, so the BIOS shows a normal EXPO 2 and CPU-Z reads the SPD as EXPO 1.2\. The low-latency timings still load: ZenTimings will show tRC 68. ## If something goes wrong - **Profile 2 isn't listed.** Update your BIOS. If it still isn't there, use Profile 1 and [contact us](https://www.wootware.co.za/contacts?ref=blog.wootware.co.za). - **The PC won't finish booting.** Wait out the first training. If it still fails, most boards fall back to safe settings after a few attempts. If yours doesn't, clear CMOS (see your motherboard manual) and try again. - **Your board won't run 8000.** On AMD, use Profile 2\. On Intel boards that can't train 8000, use XMP at DDR5-7200. - **Having trouble with your motherboard?** [Let us know](https://www.wootware.co.za/contacts?ref=blog.wootware.co.za) so we can review compatibility. Enabling EXPO or XMP is memory overclocking: it runs the kit above JEDEC defaults, even at its rated profile. Results depend on your CPU, motherboard and BIOS. ## Sources and test notes - Wootware technical team: KingBank board compatibility and refresh-timing tests on 11 motherboards, 12 to 20 October 2026; per-kit master profiles and MemTest86 runs, October to November 2026. - Wootware technical team: Profile 2 (6000 28-36-36-32) against the factory 8000 CL38 profile on a KingBank KFXW 48GB kit, Ryzen 7 9800X3D, Gigabyte B850M Gaming X WiFi6E (BIOS F11d, AGESA 1.3.0.1d), Radeon RX 9070 XT, 1 to 2 October 2026\.
