Lexar regional manager says that RAM prices are expected to double by the end of the year — 'discounts' and stabilized prices result from distributors getting rid of old stock or sourcing products from other regions

Lexar's Regional Manager for Australia & New Zealand predicts that RAM prices will double by the end of the year due to high demand for memory chips in AI build-outs. While some retailers are offering discounts on RAM modules, this is mainly to clear old stock before new, more expensive supplies arrive. Industry experts now expect RAM prices to keep rising throughout the year, with shortages affecting not just desktops and laptops but also smartphones and other devices. Consumers are advised to purchase RAM now as prices are unlikely to decrease anytime soon.

G.Skill explains how AMD EXPO ULL unlocks additional performance — expanded profiles allow memory makers to include subtiming tweaks for the first time

G.Skill showcased new memory kits at Computex with AMD's EXPO Ultra Low Latency (ULL) support, aiming to reduce memory latencies for improved CPU performance. The EXPO ULL program allows memory makers to adjust sub-timings within primary timings for lower latencies, enhancing memory performance. While faster memory speeds above 6000 MT/s can add latency on AMD platforms, EXPO ULL kits aim to optimize latency without the need for manual adjustments. These kits require stricter binning during production, potentially making them more expensive but appealing to gamers seeking optimal CPU-bound gaming performance.

Huawei-led team claims it post-trained DeepSeek's 1.6-trillion-parameter model — 1,000 Ascend 910C chips used in training

A research group led by Huawei Technologies has successfully post-trained DeepSeek's V4-Pro, a 1.6-trillion-parameter model, using a cluster of 1,000 Ascend 910C chips. This achievement showcases Chinese accelerators' capability to handle training-class workloads on domestic silicon, a significant development amid U.S. export controls. While Chinese chips have excelled in inference tasks, they have historically struggled with training, making this accomplishment noteworthy. However, the team's claim lacks specific benchmarks or comparisons with Nvidia hardware, leaving some aspects of the achievement unverified.
