" rel="nofollow - Hi I have just bought a J3355B-ITX motherboard and it is advertised as having speed up to 2.5ghz. But when stressing the CPU I have noticed that it maxes out at 2.4ghz. That means 24x100 is the most that it will run at. Should it not be 25x100 for its maximum speed when being stressed at 100% usage.? Thanks |

If we check the specifications of your board's J3355 processor, we find that 2.5GHz is what Intel calls the "Burst Frequency". http://www.intel.com/content/www/us/en/products/processors/celeron/j3355.html" rel="nofollow - http://www.intel.com/content/www/us/en/products/processors/celeron/j3355.html Burst Frequency is similar to a Turbo speed of other Intel processors. The Turbo and Burst frequency/speed is not the maximum standard processor speed. Turbo speeds occur only on a subset of the processor cores under certain conditions and situations. The same is true for the Burst Frequency. Turbo and Burst speeds are not maintained on a continuous basis. When stress testing an Intel processor with the Turbo feature, the maximum speed all the cores will achieve will be the maximum specified frequency, which is not the Turbo frequency. The same is true for the Burst frequency. In the case of the J3455-ITX board, and its J3455 processor, the Burst Frequency is 2.3GHz: http://ark.intel.com/products/95594/Intel-Celeron-Processor-J3455-2M-Cache-up-to-2_3-GHz" rel="nofollow - http://ark.intel.com/products/95594/Intel-Celeron-Processor-J3455-2M-Cache-up-to-2_3-GHz So this one is on Intel, or a slight misunderstanding of the specifications of these processors. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Also it is one where it is somewhat misleading when advertised at Amazon.... ASRock J3355B-ITX 2DDR3(SOD)/2S3/GL M-ITX Motherboard - Grey https://www.amazon.co.uk/dp/B01M9EXCYB/ref=cm_sw_r_cp_apa_0556ybD5VSKG1" rel="nofollow - https://www.amazon.co.uk/dp/B01M9EXCYB/ref=cm_sw_r_cp_apa_0556ybD5VSKG1 ASRock J3355B-ITX J3355 2DDR3(SOD)/2S3/GL M-ITX ASRock Super Alloy Intel Dual-Core Processor J3355 (up to 2.5 GHz) And in the motherboard spec at Amazon...... Processor Speed 2.5 GHz Which should be amended. Then again when Asrock show on their website .... Intel® Dual-Core Processor J3355 (up to 2.5 GHz) It is how the up to is, if ever, arrived at. |
