for the CPU RAM and motherboard. That is still a great deal almost two years later, and we were able to do this

我們組裝了一台8核心的電競電腦

Thanks to a couple of things. One:

只花了不到$150元

high-end workstation and server equipment is often ahead of the technology curve in certain ways like multi-core processors and

買了處理器、記憶體和主機板

Two: the way that businesses upgrade their IT gear on a regular cycle

促使我們成功的原因有以下幾項:

Can lead to big jumps in the supply of

1: 高階的工作站或是伺服器硬體

This older tech

通常是最新的科技

on sites like eBay, where the pricing often ends up much lower than mainstream

像是多核心處理器

hardware because it's less familiar to the average consumer and nobody's searching for it. So we thought to ourselves well

2: 科技公司因為會定期升級他們的電腦零件

Now eight core CPUs are like mainstream, so how do we take this concept to another level?

導致網路上，像是ebay

Let's build the most badass machine possible

充斥著大量舊的但是依然可用的零件。

using decommissioned server gear

而這些零件往往比市場上主流的零件便宜許多

What could go wrong? (Boom)

因為這些東西不是大部分消費者要的東西

[Music Plays Here]

導致幾乎沒有人搜尋它們

Nothing could go wrong by visiting our merch store, which has shirts hats and more

因此，我們就在想

It even has stickers

如果說

There's a link below.

現在8核心處理器成為主流

So this video has actually been ongoing since uh,

那我們怎麼把這個概念提升到另一個境界

mid May, I mean what the crap? How difficult could it be to source some

那就來組裝一台史無前例的機器

junky old stuff on eBay and slap it together

用退役的伺服器硬體以及零件

It's story time

還有甚麼能比這個更[cut]

So way back then Anthony and I, that was like way early on in his employment here even,

[開場音樂]

we sat down, and we first looked for the biggest baddest motherboard

還有甚麼能比來逛我們的周邊商品販售處更好呢?

We could possibly find on eBay. The most sockets, the most memory slots, the most

我們有「衣服」和「帽子」...其他的東西

actual

甚至還有貼紙

physical size, and we settled on this: the Supermicro H8QG6F

底下有網站連結

designed for the proprietary

其實這部影片從今年的5月中旬就已經開工了

SW TX form factor. It checked all the boxes. Four G34 CPU sockets

你看看這堆東西

32 DIMM slots for up to a terabyte of ECC registered ddr3 memory

在ebay上搜尋幾個老舊玩意兒並且組裝起來能有多難

Multiple PCI Express slots and even an on board LSI SAS controller. This thing is in another league!

事情是這樣的

Look at all those connectors, and yes, those are fans on the chipsets

從前從前

plural chipsets

Anthony和我

Speaking of which the i/o includes three Ethernet port so two gigabit for data and another one for IP mi

應蓋是我剛錄用他的那時候

Which is a remote management interface you can learn more about here.

我們坐下在先搜尋了

Next up then

ebay架上最大的伺服器主機板

Choosing a CPU; Or rather four of them. As we pointed out in our hundred and fifty dollar gaming rig video

最多的處理器插槽

top of the line SKUs for even very old servers are still being sold at a premium but

最誇張的記憶體插槽

drop down a few tiers and aha

還有體積最大的

There we go the Opteron 6276 with

然後我們就看中了這傢伙

16 cores each can be had for 30 bucks

SuperMicro-H8QG6F

So we snatched up four of those then we grabbed a case lot of

為SW TX 量身打造的架構

16 four gigabyte sticks of ECC registered memory giving us

符合了這些需求

quad-channel memory for each of our

4個G3處理器插槽

4 CPUs

32條記憶體插槽

That's like 16 channels of memory

最的可以支援到1TB 的DDR3 ECC記憶體

Hahahahaha. So then at this point we were ready to rip up the performance charts, right?

多個PCI-E插槽

Not really, so not only is this motherboard a crazy form factor

甚至還有內建的LSI SAS控制器

That wouldn't even begin to fit in any case or test bench we have here at the office

(*我們都知道那是騙人的*)

We also needed to track down a power supply with three

這東西是另一個聯盟(?

EPS 12 volt connectors in order to supply power to all of these bloody CPUs

看看那些在主機板上的排線

I mean even the highest end consumer units only come with two such cables at most so what we ended up doing was

你沒看錯，那些是在晶片組上的散熱風扇

frankensteining together the cables from two modular units onto one

多重晶片組!

success

說到這個

So then with that issue you solved we plugged it all in and powered it up

板子內建的I/O包含

Blank screen

3個乙太網路插口

The board wasn't posting. Now the CPUs are on the supported list so... what gives?

兩個GbE資料線，而另一個是IPMI

well, we ended up shelving it and waiting a couple of months for a slightly stripped down version of the same board it lacks the

IPMI (智慧平台管理介面) 用來遠端登入後台的管理介面

SAS controller and a few PCIe slots, so that's a bummer

詳情請點這裡

But it'll do at least it came with some eight core Opteron 6128 already installed

下一步

So we were able to use those to fire it up verify it was working then swap our 16 cores in and what?

選擇一個處理器

Okay, I'm gonna skip the long version here

或者是選四個

And it turns out that despite the BIOS reporting that it was the latest revision it

像是我們在$150電競電腦的影片中提及的

Was not so a desperation BIOS flash later, and we were finally in business

在搜尋結果頂端的零售

On an unrelated note anyone want to buy an unexpectedly functional quad socket Opteron board

即使是很舊的伺服器

anyone Bueller Bueller

價格依然相當的高

Bueller

但是

Oh right, no you want to see how it performs first. Huh well with a whopping

在鍥而不捨地尋找之後

64 cores we put it straight head-to-head with Ryzen Thread Ripper and

哈哈~

Intel's latest core i9. I mean this thing's gonna win with its eyes closed and one hand behind

有了!

It's back in the multi-threaded tests right. We'll get to those but first. Let's address the elephant in the video title

AMD Opteron 6276

Gaming

每個有16核心

It sucks. Like

只需要$30塊

Let me make this abundantly clear

然後我們一口氣就搶下了4個

This is a 1080 TI running at 1080p

又另外買了16支 4GB DDR3 ECC記憶體

So if you've ever wondered what a bottleneck looks like

讓我們每顆處理器都配備有4通道記憶體

This is it rise of the Tomb Raider in DirectX 12 got 10% of the performance of the core i7 7700 get

那可是16通道的記憶體!

10% and it's even worse in csgo, I mean at least it was only half as bad in 3d marking Unigine superposition

哈哈哈哈!!!

But I mean if Supermicro is to be believed

所以，然後

This is or at least was a machine that was designed to do work not games

我們要準備開始分析我們的效能圖表了對吧?

So will it blend

不

Actually, yeah in blender its 3d rendering prowess doesn't put it quite on the level of Thread Ripper work

這個主機板不只有誇張的尺寸

For i9 but it handily outdoes the Rison 7 1800 x4 roughly the same overall system cost

讓它無法放入我們辦公室內的任何主機殼或是測試機台

unsurprisingly Cinebench and 7-zip show similar results, but the lack of a VX to support and

而且為了要能夠提供足夠的電力給這些板子上的處理器

Relatively low cache per core hinders its high core count significantly compared to its more modern competition

還要找尋支援3個EPS 12伏特插槽的電源供應器

even in these multi-threaded workloads and

可是

There's more to buying a CPU than just performance too so we tested our thermals with some

就算是市面上大部分消費性的電源供應起也頂多有2條排線而已

Noctua nff 12s just sitting on top of the heat sinks that were included with our board and actually

因此我們像是在做科學怪人一樣

this wasn't bad each CPU hit only 55 degrees at the worst in AIDA64 as

用了兩個模組拼湊了一個有3個EPS供應線的電源供應器

for that power draw

並且成功了

Hone le wow that's a number that only gets trumped by our

解決完電源的問題之後

overclocked

把該接的線都插上去

18 core core i9 7980XE extreme edition though in fairness this is

將它啟動

64 cores across four CPUs

然後.......

So bottom line then umm

黑屏

Fun experiment, but did we get our money's worth well given that we bought two boards by accident

主機板根本連開機自我測試的動作都沒做

No, no we didn't but let's play a game where we pretend. We didn't do that for gaming this setup is

根據規格表，這些處理器是支援的

super dumb, but for productivity

所以...

Surely doesn't look that bad

搞啥啊?

Even though it is at the bottom of our charts like so all in we paid about

我們乾脆就把他丟到架子上

eighteen hundred and eighty eight dollars for this ghetto workstation as SPECT

等個幾個月

Using a motherboard box as an open bench style case now as soon as you buy modern hardware like a 1080 Ti

買了另一組的同型號後代的板子

the bottlenecking of that high end gear hurts your overall system value

內建比較少的SAS控制器和PCI-E插槽

But if all you wanted was CPU performance

有點令人不快，但還是勉強可以接受

And you just put like a five dollar graphics card in then our system here actually

至少它還有附帶八核心的 AMD Opteron 6128處理器

Delivers better value than Ryzen Thread Ripper, and if we had waited our testing more towards blender

我們就能夠用那些來開機

We'd have seen an even better price to performance ratio this actually makes for a, a really cool budget blender box

驗證它是沒有壞的

but if

然後換上我們的16核心處理器上...

You want to do almost literally?

甚麼!?

Anything else with your machine especially gaming it

我要跳過這冗長的一段測試和偵錯過程

Shouldn't be your first choice

原來是這樣的

Especially given the headache factor

即使BIOS回報的資料中指出

speaking of headaches do you find yourself with a headache at the end of the day as a

它是最新的版本

freelancer or small business owner while FreshBooks has got you taken care of it's the small business accounting software that is

但是它其實並不是

Custom-built for how you want to work

我們做了瘋狂的一件事-刷新了BIOS的快閃記憶體

It's a way to be more productive more organized and perhaps most importantly get paid faster

如此一來我們終於步上正軌了

You can create and send professional-looking

題外話

Invoices in less than 30 seconds you can set up online payments with just a couple clicks

有人要買下這塊未料到其實是好得主機板嗎

And you can see when your client has seen your invoice putting an end to the guessing games
