The 16299.192 is the new Win10 with fixed kernel. Is it really that bad with 25% less power? Check more info here: https://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,40554 As I mentioned, it seems to be a defective CPU. However, I in general am not a fan of the update-everything-every-second belief. Does the Intel ME vulnerability affect every machine? Sure. But that's also *IF* it is attempted to be exploited. In my particular case, these 10 machines are 100% dedicated to WCG and that's it. Not a single piece of personal information on them. Nothing. Zip. I just installed Windows and then WCG. In order for this ME vulnerability to be exploited, as I understand it, people have to visit websites designed to hack ME...or install software to hack ME. Then once hacked, *IF* there is any personal info in memory, it could be stolen. There are a lot of steps to actually be exploited. Will I patch my personal pc that I use for bazillions of personal shopping, banks, spreadsheets, emails, etc? Yes. Will I continue to avoid websites that offer free icons, free wallpaper, free dating services, and free coupons as to avoid nasty javascript and who knows whatever other computer evils? You betcha. This ME exploit has been around for at least 10 years and I thought I read somewhere 20 years. We've gone a substantial amount of time without an exploit (or mass exploit) so I'm really not concerned that suddenly now, hundreds of millions of users are going to have their identity stolen, their SSNs posted on websites, their cats held for ransom, etc. as the media is playing it out to be the end of the world. :) But the 10-25% slowdown RUMORS that are being posted on the web, if found to be true, are terrible and could result in mass lawsuits and/or hardware replacements. You can also go in BOINC Data dir & in file client_state.xml find <time_stats> & list them here. Actually find those for both CPUs, ones that work OK & one that doesn't. Just to be sure!  |

Are the same number of tasks running as the other machines. Do they have the same Run time and CPU time as the other PCs.
----------------------------------------Install HWMonitor to check the actual CPU power draw on the problem system and another to compare actual wattage used. That will determine if you're actually using 78% or not. Intel problem would still show 100%. Could always reformat/image from another computer. Did all memory sticks get recognized? Just making sure its not out of memory and BOINC is limiting a task from starting.  |

I am back again with the same problem but on a different Lenovo machine...a brand new Yoga 13 with the new 8th gen i7-8550U 8-core CPU and Windows 10 Home 64bit.
----------------------------------------Task Manager shows total CPU never exceeding 89% while WCG is set to Run Always (just like my other 20+ various Win7 and Win10 machines). All my other machines show CPU at 100%. It's also taking 5-7 hours to crunch each WU while my other machines, of various i5 and i7 chips from 2016 and earlier take 3-4 hours. Maybe it's because the CPU is running 11% slower. Anyway, I can't find anything in Windows that is limiting this CPU from hitting 100% utilization. There is nothing else running other than Windows processes. I've got the Windows Power Management stuff all set to never sleep, and the min/max CPU speeds and all that wonderful stuff to make it as fast as possible (just like my other machines). I don't think there is anything in the BIOS that would limit the CPU. I downloaded the Intel Processor Diagnostic Tool and it states everything is fine. As I said in my opening post, I configure(d) tons of machines all year long and set WCG identically on all. What could be stopping the CPU from hitting 100%? It never, ever goes over 89%...reboots and all have no impact. Windows is on it's latest version as of this week. Thanks!  |

I googled around for "lenovo throttling cpu" and found a thread that stated some manufacturers muck around and limit the CPU on laptops to reduce heat and/or use less power and/or the power supply supplied can't fulfill the needs of the CPU.
----------------------------------------The threads pointed me to https://www.techpowerup.com/download/techpowerup-throttlestop/ which I just tried now and gets me to 99% CPU utilization. Without going off-topic, I agree with the other threads on the net stating that what the manufacturers (especially Lenovo it seems) is unethical and misleading. I bought this particular laptop for the 8th gen i7 chip and Lenovo capped it!!...and without any disclosure at all! [Edit 1 times, last edit by ericinboston at Apr 20, 2018 1:30:21 PM] |

I bought this particular laptop for the 8th gen i7 chip and Lenovo capped it!!...and without any disclosure at all! That is like putting a speed governor on a race car. Why build a system which limits the capabilities of the cpu ? That is a lack of engineering and an attempt to cheap out on the materials and components. If you are paying for top performance, you should get it. And get it without ruining your machine. Minus one to Lenovo. Cheers

From the article:
This is done deliberately to either allow your computer to run cooler or to allow your laptop to operate with a power adapter that is not sufficient to fully power your laptop and recharge its battery at the same time. That is just horrible if laptop manufacturers are doing this. Another reason I won't be purchasing any. |

I have never been a fan of laptops for a ton of reasons...I understand why they are popular and have been popular for 15+ years over a desktop...but over the past few years I've noticed laptops are shipping with all sorts of power saving modes set to the ultimate worst performance to give the battery 6 hours instead of 5 (for example).
----------------------------------------In this case with Lenovo, I'm not sure if they are doing this at the Windows OEM level or if they are doing it in the BIOS. But since a Windows app can override Lenovo's tweak, I'm guessing it's somewhere in Windows. I don't have the time to install Windows fresh from an MS dvd and then go looking for all the crazy drivers. If Lenovo (and others) are doing this, who knows what else they are doing. Seriously. |

I'd like to add that this 8th gen i7-8550U CPU is pretty slow...it's doing less than 1/2 what my $420 desktop with an i7-7700. The Yoga cost $1400 which included a very steep discount. The Yoga is a great little machine, but the CPU is very misleading IMO.
----------------------------------------I find it a bit hard to compare CPUs even though there are some sites like Intel and Passmark that do comparisons. I can't believe Intel is calling this an i7. Chalk this up the #1 reason why I don't like laptops: 3x the price, 1/2 the CPU performance. [Edit 1 times, last edit by ericinboston at Apr 23, 2018 8:15:26 PM] |
