The quality degradation of the motherboard is revealed by the "revision" of a certain PC maker

In the Netherlands PC part community, Taiwan's PC maker "GIGABYTE (gigabyte) motherboard has been changed from the original model" was posted. It is said that parts and others are changed with the same model of hardware to correct problems etc.RevisionIt is called unusual, but when I tested the motherboard whose Hardware.Info was changed, it became clear that the performance was obviously degraded over the original model.

Parts may be exchanged if defective parts are found on hardware such as PC. If there is a major revision, it becomes "model change", it will be released as a different product, but in the case of fine modification, "revision change" with revision number given as "REV: 1.0" and "REV: 2.0" "Model number and UPC code (JAN code as it is in Japan) will remain, and sales will continue as the same product.

Compare price comparison search engines including Hardware.Info classify products by model number and barcode so revision products are treated as the same product. Revision information is hard to be reflected especially in net shops, and it is often that the original model photos are used as they are. This makes it difficult for end users to notice changes in products due to revisions until they open the box after ordering. Manufacturers such as Nexus, Antec, Seasonic, and XFX have customs to do revision, but the point is that performance is improved after all revisions.

However, some examples have degraded performance after revision, for example, Kingston previously reported "V300"In the case of revising the flash memory of the SSD, it has been found that the performance has remarkably deteriorated in the study of Hardware.Info. It is said that the same "invisible" version down "has been found on the GIGABYTE motherboard.


Below is the GIGABYTE motherboard "B85M-HD3"REV: 1.0" (left) and "REV: 2.0" (right). You can see that the parts used are changed considerably, but both are sold as the same product. When Hardware.Info actually got some GIGABYTE motherboards and investigated it, it is confirmed that the CPU power has been reduced and the number of power supply phases has been reduced.


B85M-HD3'sCore i7 4770KIn the results of the benchmark test using the processor, you can see that the result of the default setting decreases from "REV: 1.0" to "REV: 2.0". In "REV: 2.0", unless you manually set the turbo setting, the same value as "REV: 1.0" is not obtained.


continue"B 85 M-D 2 V". REV: 1.1 (left) and "REV: 2.0" (right) are compared in the market saying that the original "REV: 1.0" was not available. The most important change found in Hardware.Info's investigation is "Rev. 1.1" is dual BIOS, but "REV: 2.0" has 1 BIOS chip. GIGABYTE is "B85M-D2V REV 2.0"Although the description of" dual BIOS "has been deleted, since the model number and the barcode are the same, for example, the notation of the online shop that posted the original spec is not changed at all. Consumers can fully consider the possibility of buying REV: 2.0 or REV: 3.0 with different specs by seeing the specification of "dual BIOS".


Hardware.Info stated that "even if such revisions are accepted by law, it is not a healthy approach to consumers," and "Like Kingston, It is clear that we are implementing revisions after obtaining high evaluation reviews. "
