EEVblog #1280 - Dumpster Lab PC Upgrade

Dave upgrades the processor in the dumpster Lab recording PC to one from another dumpster PC. It's dumpsters all the way down...

A LOT of older enterprise PCs have been getting BIOS updates recently... In addition to spectre and meltdown, vulnerabilities were found in the Intel Management Engine that's embedded in so many of them.
I've got a 10 year-old Dell Latitude that saw an update in 2019. It doesn't even officially support anything higher than Windows 7...

And yes Dave, they all come from the same silicon wafers, and after they are cut they are "binned" into various tiers depending on their performance.

Just a note that might help someone: TDP is how much power the chip package is designed for, not how much power it uses or how hot it will run.

Back in the day 30-25 years ago, I’ve sold a lot of HP systems and had to upgrade quite a few too. Even then the case was extremely well designed. Everything was very easily accessible with almost no screws. It was a joy to work on.

Bloody hell, Dave - are you applying thermal paste or icing a wedding cake! :)

[johnpossum]

These dumpster dives w/upgrades and/or hacks are some of my favorite videos you do, Dave.

Always been a believer of the 3 R's myself - reduce, reuse, recycle. It's great.

[TheBackyardChemist]

The CPUs have the same exact die, just more crippled for product segmentation reasons. Possibly also to improve yields, that 2MB cache block might have been defective, or maybe the i5 die was too leaky to meet the TDP spec with all the parts fully enabled.

[MrJob]

I feel like these sorts of recycle moments can prolong many of our old systems into the future

Beware of TDP power ratings. They are NOT an indication of the actual power use of a CPU. It is a guideline for the thermal design, indicating what grade of cooling solution is recommended. It really has very little to do with the actual power use of the CPU. That depends mostly on what kind of load it's running. The i7 4770 is a pretty good chip, still. I have it's Xeon counterpart (E3-1245v3) running a games server, which is pretty much the same chip, only with ECC support and maybe (not sure) some tweaks to the cache. Most of the time it's just idling between 5 and 8 watts power use.

Hey dave :)
15:41 - Unfortunately all Intel CPUs made since 1995 are affected by those vulnerabilities.
11:47 - Yes, They are the same die, Intel bins the dies but they output a lot of good quality dies so a core i5 and even a core i3 can end up with a good quality die so they "cripple" them.
16:50 - For benchmarking the CPU i recommend Cinebench R15 for 8 cores or lower, and Cinebench R20 for CPUs with more than 8 core.
7:58 - That's not the stock Intel cooler - That's an aftermarket cooler from Cooler Master, I use the Cooler Master 212 EVO which is very nice and huge.

[TheBackyardChemist]

Yes Dave, this CPU has all the hardware bugs and vulnerabilities under the sun. Proper mitigations can slow these CPUs down quite a bit, in some tasks.

[DrearierSpider]

Great find! Older i7's hold their value very well on the used market (e.g. they're substantially overpriced) due to how many people want to upgrade without having to ditch their whole system.

[MrNagant]

Nice find. Anything quad-core Sandy Bridge or newer are still great chips for many tasks. It's wild that Haswell stuff is starting to get trash canned. All these computers really need is just an SSD.

[sethrd]

If your talking about Meltdown and the various versions of Spectre snaf00's, its a microcode change that shut off various things plus Bios/OS level mitigations that causes slowdowns for services and applications.

[yeet]

Did you mean the spectre and meltdown patches? If so then yes, they're also affected. Almost every intel cpu was/is affected except for some of the older atom cpus IIRC. Depends on the slow down though, she'll be alright, no "crippling" lol

[OneBiOzZ]

i was not expecting to watch an EEVBlog video and get the urge to rewatch iron skies

[pastoelio]

i wish i still had dumpsters accesable like that

13:28 - it is a copper plate, just a nickel plated copper cold plate to transfer the heat over to the copper heatpipes
