CPU Multiplier Changes~~ Tags: Homebuilt Core Systems Last response: August 18, 2009 3:40 AM in Systems Share thif_kr August 17, 2009 11:51:03 PM Sup guys~ Just wondering, I have an overclocked E8400 running at 3.6 [400 x 9] but I'm just sitting here looking at Core Temp [the application] and watching my Core's [#0/#1] frequency changing... looks like this at first: [-] Processor #0 [-] Core #0 - Frequency: 2400.03MHz (400.01 x 6.00) - Bus Speed: 1600.02MHz (400.01 x 4) - etc... [-] Core #1 - Frequency: 2400.03MHz (400.01 x 6.00) - etc... then changes to: [-] Processor #0 [-] Core #0 - Frequency: 3600.05MHz (400.01 x 9.00) - Bus Speed: 1600.02MHz (400.01 x 4) - etc... [-] Core #1 - Frequency: 3600.05MHz (400.01 x 9.00) - etc... Keeps changing back and forth while I'm looking at it... is this normal? or is it a motherboard feature? like power saving or something? thanks in advance~ More about : cpu multiplier | E-mail me updates | Report abuse Register or log in to remove hunter315 Homebuilt system Master August 17, 2009 11:54:29 PM Its a power saving feature, if you use CPUID to watch it you will also see that the voltage changes when it does that, the lower voltage means lower current which in turn leads to less power used. | Report abuse Shadow703793 Homebuilt system Expert August 18, 2009 12:15:46 AM SpeedStep http://www.tomshardware.com/forum/247006-28-running-ful... | Report abuse Noobster15 August 18, 2009 3:40:04 AM Thats Normal dont worry. Saves power, but also lets your CPU run cooler which leads to the fan not having to spin as fast which then leads to less Noise. A truly great feature. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Systems>CPU Multiplier Changes~~> Related ressources: ForumCan't adjust CPU Multiplier in BIOS ( changes won't save) ForumCpu multiplier changes depending on its temprature, help!
