Interesting. ..and very, very stupid of Microsoft. How is the user then supposed know when the CPU is is used for real and when it is not? They never stop surprising you...codysluder wrote:I'd think it would be just the opposite.
Your P4 only has one physical core, so even though your OS is telling you FAH is only using 50% of the CPU, it's lying to you. Running two clients is discouraged on that platform. There's only one FPU so most of the time one copy of FAH is waiting for the same resources that the other copy is using, slowing both WUs to about half speed.
no, betas, no limits.Was your friend running two copies of the classic FAH client, or was he running other (beta) clients? Does his computer have limited RAM?
Actually that's Intel. They make the processor present a second core, Windows can't do anything about that. If you go into the BIOS and disable HyperThreading, then you will see just the one physical core that your computer has. Because the second core is constructed out of unused resources on the physical core, if the physical core is fully loaded then the second core will always be at 0%, hence the dodgy reading. I'm no fan of M$ but for once it is not their fault...ewal wrote:Interesting. ..and very, very stupid of Microsoft.

Beta testing since October 2006. www.FAH-Addict.net Administrator since August 2009.If the computer only has one thing to do at a time, there will be no change. Since FAH is running all of the time and whatever else you want to do is sporadic, you will probably be able to notice some difference. A single FAH client with nothing else running will run at the same speed with HT turned on (and using 50% of the virtual processors) or with HT turned off (and using 100% of the processor). The only problem is that people believe that 50% and 100% means something when it really doesn't. They decide that they need two copies of FAH to use the other virtual processor, not realizing that in the end, there's still only one real processor so the two clients compete with each other.ewal wrote:How will my computer's performance(over all) be affected if I disable hyper threading?
