These are such needed reviews m8, keep up the good work!

[@Nodelez]

Hi, i wanted to know this component: in the upper part of the hdmi with no sticker, if you go a little bit to the right, you'll see a component, "f400", that component burned in my graphics card, what's the name of the component, i would appreciate your help ☺️

[@ricardomunozrecio9671]

now im getting this card, thank you so much :)

[@HackingVision]

I've got one of these cards them fuses you talk of keep blown the 2 next PCI-E power. I've replaced them 4 times tonight while trying various fixs with this card. I've checked resistance of a lot of the main components. When I think I have this card repaired it just blows it fuses again I think it could be a short have you come across MOSFETs becoming shorted on these cards what would be the most common short on these RX pulse cards. I bought the card broken it's just a project to become more familiar on how these cards work do you have any recommendations. Thanks

[@abyssillusionz]

Nice, how about XFX 580 brands ? Can you please do it ? How is it compare to Sapphire ?

[@CYellowan]

I legit wonder myself. I've had some wanky experienced with them recently.

[@arwlyx]

I've been waiting for this for a long ass time

[@andreapianini6764]

Hi, I have one of them not working and with a multimeter I found out that both the fuses of the 8 pin are burned. So in order to make it work again I just have to replace the fuses or maybe replace the vcore controller(SiC632) with new ones? Please help me

[@haydn-db8z]

I have a Sapphire RX 470 that I bought off eBay. It arrived DOA and I had to replace the two fuses near the 8-pin and then did troubleshooting to find one of the four power phases was dead. Apparently, this is a common problem with these Sapphire Polaris cards. I was unable to replace the power phase, so I removed its inductor completely and the card runs fine with only three of the four power phases and three BIOS edits.

[@abdullahmorsy4029]

I have Rx 570 itx pulse mini, it's powered by 6pin connector only and has 10A fuse to the connector. On the pcie slot it has 8A fuse. Power limit of the card is 120w, and can be changed via adrenaline or msi afterburner to +50% so 180w total. We all know that this is only the chip power and TBP will be like 30w more at least, so total 210w. Something doesn't add up. Giving the fact that pcie connector can only provide up to 75w, and the 6 pin connector is limited to 120w max by the fuse, total 75+120=195. How can the bios of the card permit something like that? shouldn't the fuse blow when using max power limit in something like furmark? well I've tried and it didn't. What do you think about that?

[@Muck696]

Which coils are used for the Onsemi 4C10N. One of them got noisy and I want to exchange it. Cheers!

[@Savirezz]

Hello, I've got what I believe an MLCC capacitor (tiny square with brown color) fall off from my Sapphire pulse RX 580. And since I don't know the value of said capacitor, I can't replace it. Can you tell me what's the value?

[@youngsairgunsa]

chances are if its a filtering capacitor, (one side is ground the other has some resistance) then any capacitor that is physically the same in size will work. it will most probably work without it, it will just not be as filtered as it was

[@BrandoLori]

How does this vrm compare with the xfx 480 RS' one?

[@ActuallyHardcoreOverclocking]

this is better

[@SyWillCry]

Is a 570 Pulse ITX PCB breakdown coming soon?

[@yanuk818]

Would you happen to know where would the fan drivers be located on the card? the 3pin components near the fan connectors?

[@Tednugent02]

it would be good that you indicate which are the voltages that should have

[@DaGunzinger]

Thanks for showing me the card I bought in depth :D EDIT: Seems my choice wasn't the best but its just a gap filler for vega anyways^^

[@Astor4o]

The card is solid, just not meant for any crazy OC. And seeing how hard it is to get any decent OC out of the 480 and 580s - you did well not spending any more cash on it, as even a beefy heatsink, binned chips and a very solid cooler would get ya no more than 5% performance boost over a cheaper 580.

[@glenz10]

so this is good for undervolting?

[@indibil]

Hi, can you guide me? Let's see what your intuition says. I have a Sapphire RX 570 NITRO +. The fans rotate, but I have no image for any port. The mother's don't beep sounds with all wires plugged. If I disconnect 8pin power, 5 beeps sound. What do you think which component may fail? Thank you

[@tcgprime]

I need the schematic/broadview of this card. please

[@DrathVader]

This is the exact same PCB as my RX 480 Nitro (non-plus). The VRM near PCI-E power connector is for memory, so the other one must be aux.

[@GBCobber]

I recently bought a used 4GB one of those. Someone had flashed it for mining I assume since I had to use the pixel patch to get the drivers working, and the core is set to 1326. Not complaining though, the 4x6mm pipe cooler is great and the Samsung memory still clocks to nearly 2.15GHz while the core manages 1390 with just increased power limit. (Seems he(she or it) might have lowered that to 142W as well)(edit: thats actually stock for this card). It runs Firestrike fine at 1375/2125 @ 75C, 50% fan. I am curious about the VRM but I'm not sure I want to take it apart. At 1390 with + 30% Pwr it generally stayed around 160-170, but occasionally spiked into the 190's, which was a bit scary. Top plate near VRM can get hot to the touch but a small fan pointed at it works wonders. Next job is to back up the bios and see if the memory timings have been tightened up, would explain why it cant hit 2250. Aside from the hot back plate at high clocks the performance is good, fans are in great shape, really quiet and I never saw the VRM efficiency go below 96% when under load. I kinda wanted that dual bios but this cooler is so much better than the old 480 nitro cooler, that, the 8 pin power and Samsung ram on a 4G card makes it a win IMO.

[@GBCobber]

Confirmed. Going by the rear fan header placement compared to the 580 Nitro + PCB, my RX 480 nitro(non +) OC 4GB has the Pulse PCB.

[@GBCobber]

OK, I'm starting to think I got Elipda ram and the previous owner flashed the card with a samsung bois. Could you check yours please and let me know what you got? According to www.techpowerup.com/vgabios/?manufacturer=Sapphire&model=RX+480 only the 8G has samsung and I def have a 4G going by all the labels, my memory timings also use a different format.

[@GBCobber]

Update! Lucky Day!!! I found a Samsung bios for this card here: www.miningtweaks.com/sapphire-rx-480-nitronone-4gb-samsung/ He has both the original and a 30.5Mh/s modded bios for download, which looks more professional than my crudely modded bios. So I flashed my card with the original bios and all good. It was indeed Samsung. Now to see what it can do.

[@GBCobber]

Results are in. Apart from the 20Mhz OC, the mining bios on this card as I bought it only changed the memory timings. In Firestrike the core does up to 1375 reliably either way, and up to 190 at lower mem clocks. Ram with mining bios made over 2130. Now with original bios it just makes it to 2250 with all default (and the same voltages). At 1375/2125 (Mining) vs 1375/2250 (Orig) the mining bios still won by exactly 100 points in Firestrike. 10574 vs 10474 at 1680 x 1050 on a stock i5 2400 w 1333mem. So I've looked at quite a few bios versions now and the Samsung def has the best out of the box timings, followed by hynix, elpida and micron, which is amazing considering it also clocks higher at its tighter timing. I'm a happy chappy now. Good luck to you and all who've read my rant. Hope it was useful. Oh, BTW, My serial No. starts with A1646. It's rare to see that number, none of the database I've seen include it. It's Samsung.

[@doblevega]

I have one Buy i need the values from the vcore vrm controller resistors somebody broke It with a screwdriver, do you know where can i found schematics or where to find the values of the resistors?

[@attiliobaldo9308]

Thank you so much for this review, it was very helpful. I only have an issue: I only get 0.893V on vcore, can it depends by the fact that it wasn't connect to video out or because the motherboard is quite old so it recognize it but it doesn't use it for compatibilty issues. Thank you again!

[@romaniantg]

I need to replace 2 coils on my board. How do I search them, what values do they have?

[@dominikmiszczyk121]

Hi! Will you tell me if you know what the values of the c4027 and c4030 capacitors located around the Y5 resonator are?

[@radimintchev4509]

I have a question. What power the fans

[@racerxvzla]

Hi, great VID, i have a MSI RX 580 ARMOR 8GB OC, i am having issues with the fans, and i beleive its a resistance or something like that but i am having issues trying to identify it, the cards work great but the fans do not work, i bought replacements same issue, if i leave the card unplugged for a couple of days the fans spin again for like an hour then, the issue returns, any ideas ?

[@vel0city96]

Yup, it's Polaris 20 now. And would you know if the RX580 GTS and the HIS IceQ2 RX580 share the same PCB again like with the RX480 GTR and the IceQ2 RX480? Because there's a pretty big price difference between the two and if they have the same PCB/cooler capability then that's a way better option for me. On the Pulse: RX500 series now also undervolt pretty amazingly, so that 200A rating isn't that bad. AdoredTV got his RX580 silicon down to like 900 mV on stock RX580 clocks of 1257 mHz at like 1040 mV.

[@ActuallyHardcoreOverclocking]

RX 580 GTR-S is the GTR 480 PCB, The GTS is weaker

[@vel0city96]

Actually Hardcore Overclocking how much weaker?

[@ThatDamnTrainCJ]

2 weaker

[@ActuallyHardcoreOverclocking]

I think it's 6 phases using 50A power stages. So 300A instead of the 360A on the GTR-S

[@GBCobber]

I'm here because I just bought a used RX 480 Nitro 4G (non+) that has that very same PCB. Mine has Samsung Ram with serial A1646. In case anyone is looking for a way to flash their mining modded card back to stock bios, I've made a little thread with some links in DrathVader's comment below.

[@newbieloncat1]

Do you have picture back side of this card? Actually I've this card from local store for a few bucks which is dead and lots of smd loses from pcb, I've no idea what kind the smd was cap or resistor or maybe something else. Thank you sir

[@vdochev]

OMG, if the Vega PCBs from SAPPHIRE are not great, I don't know what to do because I really like them.

[@aos32]

Sapphire tend to use very good PCB`s for high end cards. The PCB`s on 290x vapor X and the Fury was very good.

[@ImTheSlyDevil]

This is the entry level card. Sapphires other cards like the Nitro+ are much better.

[@yulusleonard985]

Pulse line are the cheaper not superclock version.

[@janhrobar782]

Thank you for review

[@cityzen9839]

Can i flash the bios from this card to rx 480 from xfx 110w 8pin dual bios ????

[@billkillernic]

How can it be the same PCB as the RX 580 pulse? I never seen it.. but physically the 580 pulse has a bigger pcb compared to a 570 pulse ..

[@chavo8358]

Why Buildzoid seemed so happy in these old videos? :D

[@MarcABrown-tt1fp]

Nothing much exiting going on in pcb tech that is within his reach I guess.

[@gotbass5869]

would this be the same for the nitro+ 570 8gb? trying to find a uni waterblock

[@StephenYT.]

do you think this card (580 pulse) can support 1450mhz with lowest possible voltage?

[@Visualize01]

Love these videos, just keep 'em coming! Also, will you be doing a PCB breakdown of the Asus ROG Strix X370-F when it gets released? I really want to know how it stacks up against the CH6.

[@davide30541]

my rx 570 pulse has a switch on the back of the card, near where the can connector is that overclocks the memory but underclocks the core? i cant find any info on it...

[@rickjames5068]

It's the "mining" BIOS... You can switch it to the "gaming" and OC the memory manually, thru MSI afterburner.

[@cakeisalie]

that's a NITRO, not a PULSE

[@ams8536]

MSI GAMING X 580 breakdown?

[@computertech-dx4ld]

AMD RX 570 schematic BOARDVIEW?

[@xiaxia686]

who designed the MB 24pin anyways, 2pin 12v connector for all the PCI-E 12v power, which can easily go over 150w on an 2x/3x SLI config. And PCI-E 6pin, which has 3 12v connectors only carries 75w..

[@thomashalvorson6667]

Cooper I think they use different gauge wire on the 24 pin vs the 6 or 8 pin. Not 100% sure but that's what makes sense to me.

[@ActuallyHardcoreOverclocking]

ATX spec is 18AWG for everything. Garbage PSU might use worse and some high end PSUs are 16AWG

[@thomashalvorson6667]

Also, it's the connector that's holding the power limit down. One 18 AWG stranded wire cable has a current capacity of 16 amps, and at 12 volts that's 192 watts. If the motherboard has 2 of those then it can carry almost 400 watts if it was the wiring holding it back. I don't know specs for the connector, but I'm going to also guess they overbuild/underrate them for most use cases

[@xiaxia686]

just checked Molex 26-01-3116 specifications, which have specifications both 13A per contact (16AWG wire in small connector) to 8.5A/contact (18AWG wire). it can delivery 200w with two contacts, but it is pushing it to the limit. ATX 24pin is so outdated and should really be refreshed/updated/completed replaced!

[@onurberksunal8996]

hey. i esas thinking if its stupid to buy a dead video card to use its vrm to power some other cards

[@onurberksunal8996]

Imię Nazwisko in my country i can get 560 ti for 20 $ and it seems like decent 6 phase power which I can hook up to unique k4000 (it must be engineering sample but not sure none k4000 looks like mine) and crush the clock

[@dirtyt5592]

It's a shame that a master like you doesn't work in the graphics card industry, I'll be a cynic.

[@muhammadhelmihibatullah8113]

does the RX580 sapphire pulse has the smae performance with asus RX 480? because in my country, the RX 580 sapphire pulse's price is lower than asus/otherbrand RX 480.

[@kn00tcn]

everything is the same gpu, everything can be over or underclocked, the problem with 480 is higher video decoding power usage & lower clocks compared to 580, so i would go with 580 (not sure about sapphire pulse though) how much price difference?

[@muhammadhelmihibatullah8113]

kn00tcn the difference is just depends on the brands. asus rx 480 4gb is like 270$ and sapphire rx 580 4gb pulse 235$ And yep. Im confused.

[@kn00tcn]

when it's other countries, the prices start changing based on who the distributor is, how different brands are imported, etc... this is on top of the individual models of cards, an asus strix should be more expensive than an asus dual since the strix has more features, higher clockspeed, better materials, but the gpu itself is about the same

[@kn00tcn]

sapphire's pulse is supposed to be one of if not the cheapest of any brand & model

[@FcoEnriquePerez]

So the bios for this card can be flashed to the RX-480 Nitro+?

[@diegovasquez6409]

I was wondering the same thing.

[@SimplyNonsensicaI]

micron still sells vram as elpida?

[@jacobfoster6773]

I was quite surprised to see an Elpida logo on the vram too, was wondering if BZ was going to mention it.

[@kn00tcn]

i think i dont remember seeing micron branded vram

[@Pedro-gy4ht]

XFX RX 570 Please ?

[@MarcoLoves360gamer]

I have the xfx 580 I can send pics to him

[@sheikhtashdeedahmed]

Please do mate. You'll be doing all of us a favour too. High quality high resolution pics please :)

[@miragept]

Checked the price of the onsemi MOSFETs and compared to my TI csd16321q5 and i got surprised the onsemi ones are really VERY cheap,(the TI ones are package limited to 100A) perhaps the ones i have are too good for a 17A power supply. If there is interest, i got a ga-990xa-ud3 than i can probe the switching frequency for a more accurate breakdown.

[@DmitriWeissman]

Funny thing, i got even more striped down version of this card (all HDMI/DP ports not installed - only DVI) for 119$ from Amazon brand new. It runs 1500MHz core @, +70 on voltage, +30 on power limit. And 2250 mem. It runs very well if you don't mind the jet noise from the poor cooler. Basically i think at stock RX580/GTX 1060 performance level.

[@parahodika]

Arent you getting really high temperature with this voltage and such clocks?

[@huuphu17]

Bought one 2nd hand, the 8 pin fuse just blew up after 30 minutes of heaven and with 1400 core OC on the card. I didn't think the card would draw that much power, it's still below 140w in HWINFO64.

[@The12sunflowers]

Hi!) Thanks for great technical review! And i have question. Can you explain, why Sappires Nitro and Pulse at ide have 30W power consumption?

[@bartekowca666]

no desktop notification, couldnt even try posting first comment FeelsBadMan

[@xStefaKO]

Buildzoid, man, I hear you talking but understand nothing...I'm really trynna understand electronics, I know my basics, but it just doesn't go, what would you advise me to do?

[@randomguy7503]

watch his vrm basics video...

[@xStefaKO]

I could do that, yes, but I'd like to think of some things myself, how, when and why...

[@tqnk0]

Only 1x8 pin? where is 6pin?

[@mazedmarky]

why would it have a 6+8 Pin? :D haven't you watched the video and seen the power layout of the vrm?

[@crimsun7186]

Modern cards don't have the ridiculous energy requirements of before, like the R9 390 II Devil 13 or the R9 295X2, which both needed 4x8 pin.

[@tqnk0]

My Rx 570 4gb hynix its with 6+8 :D

[@kn00tcn]

75w slot + 150w 8pin = 225w on a card that's designed to stay under 200w, TPU review of the 570 shows it under 180w 480 reference was 75w slot + 75w 6pin = 150w

[@lovelyxyz]

Vega confirmed to be worse than 1050ti

[@crimsun7186]

Considering that this is not Vega...
