Lenovo Does NOT Want You Doing This... 

where to update?

@@TheMcspreader stinkstation 💀

Is there any issues or errors like I/O or any other? Yesterday, I bought p520, w2135 32GB quadro p1000 for my nephew. Somebody told me that you have made a mistake and you'll face few irritating and un solved errors with this machine. Plzzz, guide me how to properly install it's drivers. Your kind info will be so helpful for me. Thanks.

​@@FloatingPoint00i think you may be able to use a ch341a reprogrammer to flash bios directly on to the chip, it's a bit difficult to figure out which chip to actually flash into, you'll have to look into it to figute out how.

@@FloatingPoint00 The Lenovo update software I guess.

the pcie slot draws 75 watts power as well, so its not actually super jank, just a tiny bit jank XD

It's probably 30W over spec. Still i've seen worse.

RTX 2070 super max power draw is 215W. 75W from pci-e slot + 75W from pci-e 6 pin +108W from sata adapters = 258W so it's not evenclose to being a fire hazard.

@@bence.gabor.slezak Nice, I forgot the 75 watt from the board. That means this setup with dual sata and the one pci-e is actually 399 watts of headroom. You made the same mistake of thinking the pci-e 6pin is only 75 watt. Read the label, these non-standard oem PSUs design their 6pin to handle 216 watt. They mostly sell prebuilts without discrete graphics so the cheaper 6pin is on the psu cable. When a customer adds discrete graphics, they use a properly thick 6pin to 8pin designed to handle the full 216 watt. People need to stop pretending 6pin means 75watt or 8pin means 150 watt. That is an old standard ignored by everyone today. The wire thickness now tends to be 16awg which handles over 300 watt. The newest modular PSUs that are 1200 watt or higher come with dual 8pin to 16pin 12vhpwr rated for 600 watts. On the newest PSUs, their 8 pin pci-e connectors are designed to handle 300 watts each. That makes the new "standard" for 8pin pci-e to be 300 watt. There is no real standard, read the psu label to know how many watts the 8pins can handle. If you use adapters make sure they are 16 gauge wiring and are rated for 300 watts on each 8 pin.

@@_PatrickO no, that was just the worst case scenario, but even that is more than good enough. People use those numbers because that's what they can find on the internet. Nobody will go to each psu manufacturer to check what their connectors can handle.

Thank you! It's actually the opposite for me, I've known about windows, but didn't realize you could upgrade macs until recently

14 cores...only uses 2.

@@jrshaul doesnt mean the cpu is not bottleneck, its not as simple at usage percentage or number of cores.

That is both terrifying and amazing!

@@aChairLeg terrifying is the best kind of amazing. Means you are doing something right (in the worst, most sketchy kind of way)

I was thinking the same thing putting 2 connectors to the same wire does nothing, 2 separate satas should be able to provide 108 i believe, i could be wrong

nice. So if you have the Quadro GPu and the RTX 4080Ti together ?

running a Huananzhi X99-8M ( only dual channel sadly ) with a 1650-v3 ( cheap as hell ) overclocked to 4.1 and it runs anything a throw at it

If I only could update my x99 to a cheap i7-5960x from a 5920k. I already maxed out the memory to 64GB.

X99 were a beast of a system.

@@monad_tcp I had a 5820K up until 3 months ago. Saw the prices of 5960x dropped so I bought one. It was also time to change thermal paste so I thought might as well do everything in one go.

@@monad_tcp you can find a 6950x, which will likely work with your motherboard for under $200 on ebay. I did so a little over a year ago. They may have dropped even more.

I currently have an Optiplex 7010 SFF, I7 3770, 16gb ram, SSD, Rx 6400 low profile. I was interested in this Lenovo P520 as it can fit full graphics cards in it. Is the A770 a good choice if the P520 I order has a 900watt power supply? What's the highest graphics card the system could support? I've Google'd and looked all over and you're the first person I've seen to have a good graphics card in a P520. So any input would be appreciated. What's the wattage on the two 8 pin connectors that come with the 900watt power supply of the P520? Thanks in advance!

Pro Tip: don't compare computational devices to cars it never ends well. With time, processors/processor architectures get way more efficient and are able to do way more. The only thing slowing down modern systems terrible software design. I.E Bytecode on L2 VMs, bad kernel design, etc. The 2690 should still work for modern workflows, but it might be time to upgrade depending on how expensive electricity is, and how important reliability is in your case.

Thank you! Too many people just think you need the newest and greatest CPUs, but when you look past the consumer chips, and look into HEDT or server chips, there is serious power for really cheap.

@@aChairLeg literally its just so fun to see xeon workstations become gaming pcs with just a couple of upgrades altho sumtimes it gives tons of problems installing stuff but when u solve those it just feels worth it

As a side note as well the original PSU I would say it still pretty freakin baller, 80 plus gold for a PSU that old is amazing.

Wow, that's an awesome build! I was considering a dual socket build, but wanted something that was a bit more of an all-rounder and closer to $500. I for sure want to try doing a dual socket build in the future though

@@aChairLeg yeah for gaming the single slot is way better value! Video editing and machine learning the dual socket platforms are amazing! So many deals on eBay all the time for these 2nd hand machines I might end up with another one if do any heavy AI model training that can justify it 😀.

The PSU should trip when pulling more than 108 watt from the dual sata cable the same as when he tried to pull more than 216 watts from the 6pin pci-e cable. When he added the dual sata to 8pin and used both the original 6pin and sata, he raised the available wattage from 216 watts to 324 watts. That is why the card worked when using both sources of power.

Thank you!

Thing is, it becomes worthless quickly. Manufacturers of enterprise level computer hardware typically hike support prices after 5 years, encouraging anyone on old platforms to quickly switch off. Also heightened power consumption effectively make it cheaper to buy new more power efficient models, and get rid of the old ones. However I do see why it would make sense for consumer use, as consumers tend not to get punished for high grid usage in the same way buisnesses do.

Most hilarious is the power/performance ratio, followed by an electricity bill 12 months later. Those enterprise customers are saving money just a few months later by upgrading to something more recent, probably even sooner if they manage to sell it for a good price to some sucker on eBay.

The psu should not allow pulling more watts than 108watts from an SATA cable with two connectors on it. The 6pin pci-e is designed for 216 watts as confirmed by the label. (non-standard PSUs used by OEMs all seem to be designed for 216 watts over their 6pin pci-e, they just size the wires appropriately). Amazon has both dual SATA to 6pin or 8pin cables and 300watt 6pin to 8pin adapters(marketed to crypto miners). The safest solution so you know all wiring and adapters can handle the current load is to buy a dual SATA to either 6pin or 8pin, depending on what your card needs. No need to try to find a 6+2pin(which may not exist). These dual sata to 6 or 8pin adapters should be designed to handle the full 108 watts SATA can supply. So no fire hazard. If you tried to pull more, the PSU should trip before a wire gets too much wattage. For the pci-e 6pin, buy a pci-e 6pin to 8pin that is rated for 300 watts or more. That is well above 216 watt and thus the PSU should trip before the wiring started to get hot. This should be safe. The video even confirmed the PSU will trip and turn off if he tries to pull too much power from the 6pin. When he added the additional dual sata adapter, he added another 108 watts of headroom, so the PSU no longer tripped and it works fine. I would use the sata adapter if I had a 6pin+8pin card or an 8pin+8pin card that uses more than ~175 watts. For ~175 to ~270 watts, I would use dual sata to 6 or 8pin(108 watts) and a 6pin to 8pin(216 watts). If the card is under 175 watts and you only want to use the 6pin, you'll need to use a 6pin to 8pin that can handle 216 watt and then use an 8pin to dual 8pin that also can handle over 216 watts. (16awg adapters should be able to handle twice that) It is arbitrary, but I would stay under 80-90% of the max draw of either configuration to ensure stability. Lean towards 80%. If you want more wattage for a xx80 or xx90 card buy a second dedicated psu for the pci-e 8pin connectors and jerryrig it that way.

I might need to, last I checked RPCS3 barely opened most games, but it seems to be completely different nowadays

The best way to do it would be to use the PCIE 6pin, adapt it to 8pin, then use two different sata cables for the 6pin power. Either way, after letting it run games for a while, my cables weren't even warm with the RTX 2070, so I'd use it if I needed a budget workstation personally

@@aChairLeg Yea its probably not a problem because many times they underrate the products limits to be safe. As a consultant for projects involving pressure washers I have seen people use 4amp wall plugs on 10 amp motors (with 40 amp starting peak current) and the outlet was warm and there was melted brown scorch marks around the plug but it was still in use until I discovered it while doing quality control checks.

Not with the power consumption and dated architecture it has.

@@samialameddine7308 When I look at the i3 12100 and the i5 12400 it does trade blows. Yes the power consumption is a lot and the dated architecture has it's disadvantages but I would say this would be able to beat the dell optiplex's no problem.

Under normal load it will never draw the maximum it can

So far I'm not aware of any workstation motherboards like that. I think your best bet would be a TR4 motherboard with a threadripper 1950x honestly.

@@aChairLeg thanks!!

I actually did get one, but decided to not show it off. With that cable though, my 1080ti was able to properly run games without crashing the whole pc.

Awesome build! Yes, I was able to install windows to my m.2 ssd in the adaptor, and boot off it with almost no issues. Some pcie slots didn't like it, though. I believe I had to install it in the bottom slot for it to work on mine.

@@aChairLeg Ah okay make sense, will give it a shot. Thanks!

Now that's just scary haha, I love it

You can, but firsthand, those units do tend to fail en masse after around 7 years. and I don't recommend overloading the PSU in any case. Old, overloaded PSUs *will* create a worry of fire no matter the quality. I've had IBM units fail firsthand in production, while only at half capacity. There is a reason why server equipment tends to have dual PSU. Not only for increased power, but for increased reliability

Thank you!

Linux and a RAM upgrade should serve you well for a few years. If you're only hitting up on a RAM limit from opening tabs and not closing them or whatever, switch down to a 6th or 8th gen i5 and spend some extra money on a bit more RAM. Also try to optimize your workloads in the configurations. You'll be surprised how much instruction capacity is just thrown away for needless initialization and whatnot. The curses of not having sensible defaults

Maybe a little overkill, but it'll last you a while haha

@@aChairLeg Don't disagree, if you can afford the power consumption, I don't see why not. Matters your priorities of couse

I'm also an idiot so if the wattage draw is too much please ignore me because I really am fuckin stupid lol

CS:GO and Valorant are good ones, I was actually looking at testing RD2, but wasn't sure if anyone plays it anymore haha, I'll for sure add that to my list. If I do another high-end system anytime soon, I'll most likely add Cyberpunk to that list as well. Thank you!
