Another GTX1070 blew with me and mine P375SM

Yeah guys another one....

I don't even know where to start.

Well in 2017 i got a GTX1070 from ebay user "upgradeyourlaptop" as everyone know (i think) is eurocom representative. Two months after the card blew lots of resistors and no more video for me.

Then i got my 980m back on and continued to use till Apr 03rd when i got another 1070 from "upgradeyourlaptop" the same model same type of pcb.

Was using fine and today again the card blew.

Here are some pics:



I had the blew resistors removed and cleaned the back of the card with isopropyl alcohol and a soft toothbrush

I don't know what i am doing wrong... could this be a problem with my motherboard? my power brick?
I don't think that it is because i used the 980m without problems for as long as I remember..

Here is my afterburner config when i'm playing games, and by the way i never let the card co beyond 83ºC (181.4ºF)



I rather use the fan's at 100% then let the card melt and for the thermal pads i'm using arctic ones
What should i do?? the card still works but i think it will blew up soon and i don't have any idea what is the cause...

CAN someone PLEASE help me out with this?? I used my vacation payment and right now i don't have any means to get another one T_T

 

"upgradeyourlaptop" is Eurocom, from the green PCB I would guess that is the GeCube sourced 1070. These things are notoriously poor quality, you will find dozens of threads of here from people who've had them fail. You likely did nothing wrong, the card is just a POS - and to be honest i'm surprised Eurocom were still selling them in April this year given the amount of failures they were having. You can try contacting the seller about it, but I doubt they will be much help. Not sure what other options there are for the P375SM - there is an MSI 1070 but that may not fit in the chassis without modifications.

 

Thanks for the reply, i don't mind making the modifications if it works. I didn't even knew that this card was faulty i even bought the card two times... they could tell me about the problem and helped me out :/ because i reported to them that the first card blew :/

 

Oh yeah is possible for me to just change the resistors? i have a bad card here so i can extract some parts..

Does anyone know what value are those blown resitors?

Here is the card that i can extract the parts:

 

Don't bother trying to fix it, you should contact eurocom and tell them to replace the card, you should have warranty. Ask them specifically to replace for an MSI version of the Gecube Full GTX 1070 version.

The GTX 1070M version is, as already noted, known for blowing up.

 

@bennyg is the person to ask about the 1070's, he modded two of them into his P370EM. You could likely do the same, and I plan to as well

 

He has MSI versions, they are very different from GeCube versions.

 

Yeah i contacted upgradeyourlaptop stating what happened to see his answer, if he just ignore me or says that theres nothing he can do.. should i go to ebay for a refund?!

 

If the option still exists yeah. They clearly gave you a faulty product.

 

I've oppened a ticket to eurocom too and posted my paypal transaction ID well i hope they do something i got two cards same mode same vendor and no one told nothing about the problems that this model have even afer i told them that i was buying it because the card blew by itself.

 

Worst case, you can

Yep, he does. I was just stating his options
Worst case scenario, since you bought it through ebay, you can contact paypal if you have bought it withing something like 180 days and try to get a refund
If not, I'm afraid your screwed aside from trying to fix it

 

Ok eurocom reported back and told me that the cards are without warranty...


So there's nothing for me to do just threw the card's in the trash bin and deal with my loss? like USD2.500,00 (here in Brazil is 4x soo yeah almost an old used car)...

Is there someone who passes this that can help me out?

 

Has the transaction been made within 180 days? I'm assuming not, but if so you can contact paypal.
If not, you can likely contact them anyways.
You can try to get the card operational again by fixing what broke, but I have no clue how and would leave it someone more experienced than me to explain

 

Yeah just got back a response from Eurocom i will RMA both cards to them and they will see what can they do at least i will stay with mine 980m and i hope that the cards can be fixed.

 

Welp glad it worked out

 

It's odd for the passives to die first.

 

beware, they might just get replacement cards and nerf the TDP so hard, that it barely won't blow up, but in turn will get performance like a GTX 1060.

Don't accept any GTX 1070M cards, only GeCube GTX 1070 non M or MSI GTX 1070.

 

If he gets the Blue PCB GeCube he can actually invest in SLI

 

Yeah, the full GTX 1070 is basicially the proper and revised version of the GTX 1070, also it's an actual full GTX 1070 card. The only issue will be how to cool that thing. The heatsink in the P375SM-A will need a rework in order to cool it down properly.

 

From what I remember, its just the top part that needs to be milled, it looks to have standard form factor. I can take another gander at it though. I do plan on getting them, as I already have all the parts for SLI and the eDP panel

 

I think they will not replace my cards but i will post here when they arrive

 

As long as you either get a refund or a new card, you should be happy

 

Those 1070s are only for 90W. Seller flash a higher TGP vBIOS so they go poof after a while...

This looks like a great (incl. SLI) alternative:

Some of the lucky ones can around 115W, or a bit higher, but the MSI's have been tested at 200W+
Glad to see you're back

 

Looks like a very robotic but robust layout on that new card design.

There is always the option of swapping vrms and caps if your into that on the new card. You can usually find higher specced pin compatible options.

 

I run my MSI 1070 at 230W 24/7, unless I'm hauling the 230W power adapter around instead of the 330W brick. Then I keep it at 150W.

Very over-engineered card.

 

What's the VRM rated for on that card?

 

Which person were you referring to, Meaker ?

 

You, since you were the only one to post since my last one.

 

I thought you were asking the OP. This is why the quote button exists.

 

Prema has already answered that question and the OP has empirically measured it unfortunately.

I was merely curious as to the chips and current handling capacity of the MSI card.

 

Khenglish said the VRM's can handle 300W.
It's supposedly 25A per VRM or something at 90% efficiency. phase doubled. i don't really understand much, with 40A max supported (absolute maximum 60A?).

http://www.ti.com/lit/ds/symlink/csd87350q5d.pdf

 

The problem is heat - in my 1070 VRM MOSFETs often reaches 130°C, when core has only 75°C. For some reason, there is no thermal protection for MOSFETs itself.

 

That's usually the issue with a vrm, the heat rather than rated capacity. It will often run hotter than the core.

 

I dunno about the 1070 but for example 980Ms were missing 3 VRMs for some reason. I am running mine with 6 VRMs (3 original + 3 additional) to distribute the load and my 980m has been running solid ever since. Maybe you can see if there is a place on the board were you can add more. Or as previously said change the ones you have for better ones.

 

@Falkentyne
1070 has only 3 power phases, and they are separated by a black capacitor
I also thought that there are five phases of power, but this is not true (((
msi1060mxm 2 phase = 40A x 2 phase = 80W
msi1070mxm 3 phase = 40A x 3 phase = 120W
msi1080mxm 4-phase = 40A x 4-phase = 160W
for which the answer to the two left-hand phases is a riddle ((((


my msi1060mxm worked on 140 watts
further was too lazy to flash a new bios means 60A this is not the limit)))

can anyone shed light on all this? where are the other two phases? for what do they answer or is it food memory?

 

Que?
MSI 1070:

5 inductors in a row
10 fets in a row. 40A max each, (edit) 400A* theoretical maximum. I think it's overspecced so that the VRMs run very efficiently. By the datasheet @Falkentyne linked, thats only ~1W each per chip at stock loads which is so little it would probably be ok with no cooling at all.

I power modded my 1070s (the one pictured above) to 200W up from stock 115W and was stable as anything. Never had a VRM related crash or other instability on a long high power benchmark like GPUPI

* Edit: I previously had 320A max for some reason. 10x40=400. Brainfart. Probably thinking of the P870 CPU VRM which has 8 of the same fets for 320A

 

Yes, at least 320A, although not sure what that translates to in watts.
The 6th phase is probably for the memory.

I had no problems putting 230W through my 1070.
I just can't overclock the core as high (max +130 or 135) since it's reaching its full limits minus the "temp throttling" feature, so it reaches its true limits at 1.062v-1.050v.

At 115W, you can put +250 into the core since all you're doing is throttling anyway, you will never ever see 2125 mhz. (except in some extremely old game that puts such a low load on the GPU that it boosts all the way past 2100 mhz without reaching TDP).

 

320A will be at around 1.2v or the like but that will have the VRMs running SILLY hot. Running them about 30-50% will make a lot of sense design wise.

It does depend a bit on the phase layout, a multimeter on the inductor outputs would confirm.

The Clevo card is a 6 phase for the core and 2 phase for the mem on the 1080.

 

Hey guys just an update, eurocom have my cards already will wait now to see a position from them, by the way one of the cards was still working even with all of those blown resistors!!

And man! i wish i got the card that @Prema mentioned.

 

looks like ill check out that card when i consider a gpu upgrade

@Prema so is the blue pcb design a new Gecube revision card with beefier power delivery and sli connector? or where did it come from exactly?

edit: so it also seems to be a Gecube card, only that the blue PCB is for the "1070 proper" rated at 150W whereas the good ol' poof style Gecube with the green PCB is rated at 115W, at least according to the taobao posting...

I was the one mentioning it....

And yes, the card has much better power supply, due to much more VRM's the card makes the VRM's run cool and the voltage is much cleaner than the other Gecube version. The Blue PCB card is TDP limited to 150W, however it should easily be able to handle more.

 

I'd still be wary of a card that's blowing passives.

More vrms is not necessarily better, you do have to look at what is being used component wise and in what configuration.

We are comparing to garbage I'll grant you but still....

 

@Meaker@Sager could it be something wrong with my power brick or even my mother board?

The weird is after i upgraded my crossfireX (8970) to a GTX980m i've got no problems... but as i upgraded to the 1070 man the card lived for about 3 months both of them. The first time i thought that the problem was "me" something like bad instalation some crap going inside the notebook to make the GPU blew.

But after i got the second 1070 all of them from eurocom, and it blew in the same way and almost at the same timespan (3 to 4 months old) as the other 1070, i was like WTF, my notebook is busted.

Then after looking in the forums and talking around wih people, the conclusion that i got and it seems validated in this forum is that this model of 1070 the green PCB, is faulty.

I hope when eurocom contact me they give me some good news (like i get the MSI card which i doubt it will heapen)

 

but thats the green pcb model blowing up left and right. no reports as of yet concerning the 150w blue pcb model... someone in the other thread mentioned specifics as to the choke and mosfet model numbers tho.

I more meant the one that is still "working" but a good vrm should shut down not blow up so I don't know how much I'd trust the other one.

 

You are going above what the motherboard was specced to. However it's unlikely to be the mobo directly imo.

 

Especially since @bennyg runs dual 1070s in his P370EM

 

I've seen even the big Clevo 1080 cards with blown supply voltage caps. I don't know what it is with Pascal, but Pascal cards seem to put out a lot of noise on the supply voltage rail which blows out caps.

As long as the blown caps get replaced and not simply removed, I would think the card should be as good as new. Leaving them off on a card that already doesn't have enough though is concerning.

 

At up to 200W each in full beast mode. Sustained for 13mins straight, to complete this GPU only benchmark

http://hwbot.org/submission/3792806_

That's unfortunately the difference between the MSI 1070 vs the rubbish one the OP was sold.

170W limit per gpu while gaming to avoid power throttle on CPU. But being helped with water, they were kept cool.

I would expect later P37xSM models would have more robust power delivery to the slots, not less, given the GPUs became more power hungry over time (880M especially)
