BGA on Desktop, IT HAPPENED!

Not gonna lie this is actually hilarious

 

BGA on desktop has been a thing for years in SFF and embedded systems.

Spoiler: i7-4770R (BGA-1364)

Spoiler: i7-5775R (BGA-1364)

Spoiler: i7-6785R (BGA 1440)

Spoiler: i7-8700B (BGA 1440)

The thing in the OP looks like someone took the effort to convert a BGA CPU to LGA. @Mr. Fox wipes away a tear.

 

Yup, the BGA filth has been creeping into the desktop space for a while now and I have even posted about it before. If there are people stupid enough to buy BGA laptop filth, we know with certainty that there are going to be people that are equally stupid when it comes to desktops. Probably even safe to say that stupidity defines the majority. I fully expect this technology brain cancer to metastasize and spread and become worse over time. It will be labeled "progress" and there will be no shortage of retarded Kool-Aid drinkers.

 

Looks neat, but is pretty late

 

It is a nice technical stunt. I do admit that. Not that it was a desirable thing, but impressive to the extent that it actually worked.

 

Checking TaoBao, it seems that you can purchase an unlocked 4980HQ for ~$100. Compare this to the ~you'd be paying for a used 4790K and tbh thats a bargain deal. Either way, Haswell is expensive to buy into

 

If performance is not that important you could save a few bucks going that route. A 4980HQ running stock does not perform as well as a 4790K, and it's only partially unlocked with functional limitations on top of that. Once you commence to overclocking the 4790K, it totally obliterates the 4980HQ's performance. But, this is status quo for BGA and expecting otherwise would be unrealistic. And, it is still cool in geeky way that they pulled it off whether it is desirable or not.

 

None should support buying BGA in any way, shape, or form ! Only exception... toys, wifi routers, tablets, laptops below 13-14 "size, smartphones etc. Don't support the Devil!

 

4980HQs also work with PGA adapters on laptops.

Was considering a T440p with one of those since it has the Iris iGPU (similar or outperforms the GT 730 with less fuss), but couldn't find a good enough deal.


In terms of overclocking for daily use, it'll probably reach the same clockspeed or just a hair lower than normal 4790K. Given that the 4980HQ is a very highly binned chip.

In terms of practicality? Just get a 4790K.

 

However, this would make a neat HTPC chip because of the iGPU IMO

 

Only if the iGPU is Iris though.

Even then you would have to increase the tdp through bios but that might not always work.

@D2 Ultima locked to 47w long even on desktop mb?

 

Why would the board matter for a chip lock?

It wouldn't matter what BIOS settings are available if the CPU is locked. The BIOS settings will be ignored and the chip limits will apply. I think LTT even mentioned something about it being locked in his video if I am remembering correctly.

 

Locked chips you can't increase power limit on. The 4xxxHQ you can... but the chip denies anything past PL1 47W.

Even if the settings are correctly set. The CPU itself says sod off. In practice similar to a locked chip but in technical terms worse.

Powercut in throttlestop would help but no idea if the board will handle that much power.

Running +70w. Don’t think he use TS.

 

How long does that sustain? I know some 47xx did it randomly but never seen a 48xx or 49xx.

Never says explicitly unfortunately.

The uptime on that video is only 9minutes so I wouldn't say for very long.

 

If he can do it for 10 mins stress he's clear. I believe PL2 can be active for twice the rated seconds (not sure if this is just sky/kaby/covfefe) which is 2.5 minutes x 2

Might be.

Won't know for sure though, unless someone directly asks him.

 

Around 2 minutes with power above 41-45w. Don't count in the whole time.

 

Over on the forum post, I don't remember who said it exactly, but someone said they had it (4980HQ) running at 100W+ or something close to it

 

The question is for how long above 47w, not how much above 47w.

 

I'd be surprised if it could hold that indefinitely.

Not long enough. It needs to be forever for it to be good.

Alright lads, just placed an order for a 4980HQ (LGA 1150, not the PGA version which does exist)
I'll let you know what happens in a few weeks
All in all, $110 well spent

ha sweet! looking forward to this from a nerdy/geeky point of view

Me too! It looks to be interesting and will likely be my main PC until I can get a decent MXM card

 

I wonder; has anyone done a BGA to LGA conversion for Broadwell mobile and later generation CPUs?

 

It is making me think what ur asking lol... be cooler ans very cheap to upgrade my ranger with a 4k series bga with a pga adapter board. The soldering part is easy. I would want an hk or 6 core with it 8th gen so nvm... lol

Not broadwell though

 

With the microcode mod to allow OC'ing that doesn't surprise me at all, might revisit that again, but with so much speculative backdoors being found I'm not to keen on running a version 0 micro-code with zero patches, and it needs a voltage bump, I got my 4720hq to some 3.8Ghz 4 cores, and got a CB R15 score of around 850-860 points, yes, its better than stock, but its also a bit unstable and it crashed(TBH, forgot to remove my undervolt, so I got that at -40mV UV, maybe going for +10/+20mV makes it stable.

And regarding the thread topic, there has been BGA's in desktop since core2duo time, in all in ones mostly.

 

Well VIA has been doing so since they made their first mini-ITX boards and has set the trend for soldered CPU systems, now blame VIA folks

Regarding those dark magic CPUs, I may buy one and build a system based on mostly Taobao parts, given how easy I can buy parts from it. Some of these chips cost as much as a second-hand Haswell i5 so certainly worth considering if I'm gonna build a budget rig. Just have to make sure not to get a Gigabyte motherboard.

 

Unfortunate update, the seller has canceled and refunded my order, but I'll see if I can get another chip

 

If you get a working example that'd be quite fantastic. Let me know.

 

Come on man. this is overreacting.

Just different people have different needs, wishes, requirements, or whatever how you wanna call it. You know my stance about this, i prefer a portable machine thats powerful than a super thick and hard to transport machine that doesnt perform better in games and maybe 25% better in absolute CPU bound productivity.

Regarding repairability and costs. MXM boards cost the same as a full motherboard for most laptops.

Its a very well thought out decision

 

And there's the problem.
A LGA CPU is only about 3mm larger than a BGA CPU. The die is the same size. So is the housing.
So why can't they just install it on a notebook that isn't big and heavy? Maybe because having to account for 4mm of IHS takes brain cells and some work and people are lazy?
I mean.....4mm....count it boys. FOUR MILLIMETERS...

But hey, you know, Intel has to get rid of their trash bin cpu's somehow! Costs money to just throw them away. Or they could just give them to the homeless or less fortunate for free. Free F tier LGA CPUs'! Here you go.

 

problem is that consumers nowadays tend to count each and every mm that their laptop is thinner... *rollseyes*

Sent from my Xiaomi Mi Max 2 (Oxygen) using Tapatalk

 

A socket adds about 2mm, the heaspreaders adds 2 mm etc. Thats already 50% more thickness of most ultrabooks. Thats like 80% of the market now. Intel offers 0,0% support on desktops LGA CPU's in laptops so if you have a large scale business you wouldnt receive any support and design aid etc which is a huge financial risk.

and to be honest i think my AW15R3 is already thick enough :d dont want it even thicker. 4~5mm more would be about a 30% increase of the bottom base if I dont count the height of the feet.

 

and i count their temperature. 96, 97, 98c

 

This should come as no surprise. All of the kiddos and preppy Facebook jockeys value style over substance. In fact, they're actually unable to identify or define substance, so style is the only thing that matters to them. It's OK if it overheats, throttles and runs like crap as long as it looks cute, has the right brand logo for status within the clique they are part of and their friends approve of it.

 

Apple..what? Huh? I didnt say anything.

I guess I'm one of those kiddos in this regard... as long as overheating can be addressed with a cooling stand. To be perfectly honest, I still had to use the same cooling stand with all the thicker laptops I had before, except one with very heavily power-throttled gpu despite respectable thickness - that thing never ran hot unless the exhaust was completely blocked. Bottom line, thicker doesn't necessarily mean better cooling; more likely, it means cheaply made and poorly engineered. Just my two cents.

 

Unfortunately, that captures the state of notebooks universally at this point in time. Honestly, I cannot identify even one (regardless of size, weight or thickness) that I can honestly say is truly excellent on all counts. The extremely rare example of a model with a thermal management system that is not an abortion is cursed in one or more additional areas, such as firmware cancer. Some just fail way harder than others. You're correct that thick doesn't necessarily mean cooler running, but thin is almost a guarantee of high temperatures due to limited capacity in the form factor. Simply put, you cannot fit 5 pounds of sand in a 1 pound sand bag. For a big and thick notebook to run hot is just downright inexcusable, I don't care who made it. That is a sign of incompetence, not giving a damn, or both.

 

Remember PGA sockets?

I do.

 

Yup, absolutely. Getting rid of pins on the CPU and moving pins to the socket was very smart.

I also remember SECC, SECC2. Glad that is gone as well. Was better than BGA, but it still sucked pretty bad.

 

the statement itself is fine and it is true. however in reality it couldnt be more wrong. the OEM/engineers are competent to a certain degree and they know full well what they're doing, since OEMs are comparable, thicker does mean better cooling for 99%, and it has been for a long time now.

the sad part is, these trend following consumers are brain dead vs the people who get thin/light/bga for their actual needs. the former would bring in all these reason into argument while thinking it's a superior product. when we get to core of the problem and they can no longer argue, they'll argue as "opinion", "preference" and in those cases, i have no problem calling them out that their preference is $h!t simply because they just follow trends.

 

Read the title.

Thinner and Lighter Laptops Have Screwed Us All

The pursuit of thinner, lighter laptops, a trend driven by Apple Todays Jokebook manufacturers, means we have screwed ourselves out of performance.

 

LMAO when you have a new gen hardware thats tagged "i9" loses to 1-2 year old i7 hardware you know u got some serious problem. even the sheeps will realize there is some serious fk up in the design and company decision to continue making it thin.

no doubt these engineers are competent, i think they just dont give a damn and must have A LOT of pressure from marketing or upper management to "keep it thin as much as possible regardless of throttling".

im just here imagine that some engineers working for apple, saw this and then they knew whats coming up but didn't care cause had instructions to follow. ROFL

 

Not only Apple make thin trashbooks and with flimsy cooling. The whole notebook industry is eqal now. No differences! The bell sheep is Razer and Alienware. And we both know the end results! All other will follow same road.

 

Your point?

PGA is still around in AMD systems.

 

He said in short no IHS
