I had one 780 ti DC2 blow up for no reason as well and it was my best card as well (ASIC 61% 1340/2050 no voltage increase). Core exploded, it was a bad time

And also on air still, didn't even get to run it cold.

Oh I think the issue has been found. There is a damaged mosfet on the back of the card: http://i.imgur.com/cUKKfSc.jpg
Q501, ignore the arrow.

It has clearly some physical damage and does not give resistance values like the same one next to it.

Markings are
B20
P03
CFL0325

Do I truly need one there to run the card, and could someone explain me what the markings mean and which of them are relevant.

[nickshih]

Have you guys ever seen anything alike. I've never seen a graphics card preventing a whole system from turning on. My first card died due to bug with gpu tweak. THis time I haven't even soldered the ln2 mode on. Just shutdown while watching a video lol. Matrix cards die from their own complexity. Damn matrix, what it gave me - a very annoyed feeling and an empty wallet. Cba with graphics cards, they die too easy. I'll just get my dewar filled next week and run some superpi, that is some enternainment I'm telling you, to see not exact in round after a long waza.

EDIT

Wow, I tried turning the rig on with only the left power connector and it powers on fine and posts without vga being recognized properly but still. So the 8 pin connector or something after it is shorted. Someone tell me how to fix this and I'll give you a cookie.

Hey bro .

i think ur VGA shorted inside . And about the 8x issue .

i tried over 20 pcs VGA here .Every card is fine to be 16x

it Should be VGA problem ..

[nickshih]

Sorry i was too busy on this baby. If anyone has issue . Feel free to send me msg..

[Luumi]

Well nick I guess its the board, since 3rd slot is X2 but I cba to do rma atleast now. I'm sure the card wont power on due to that burned mosfet I just linked, what do you think? Nice board btw, can't wait to see it on retail.

So sad to see that u have problem.

^ ahaha loud,looking forward to seeing the X99 OC formula board

[Splave]

Playing some Pifast and then seeing some limits of training my new kit

[bullant]

Wow that's crazy Splave,35-36-3-3 1335 tight at 6.6ghz too,nice training

1371 6-9-6 tight is nice too

[XBrytanX]

sick
that's rally nice chip ,congrats

[Splave]

Thanks men

[bullant]

So I was have a chat with Splave just recently and he was kind enough to give me a few tips,thanks big guy .Anyway he was also saying to try my chip that has a wounded imc,so i did, I didn't get any passes tonight but it shows the board is quite impressive






5Ghz run board was pretty wet buy now and OS was trashed,was loosing bit of efficiency

Great runs bully, 2860 is looking beast I'm sure it will finish in drier conditions. Just shocked at the amount of water in the last pic

[bullant]

Yeah mate its sort of like that after 1 hour of benching,I should really vas the complete board as I've only vassed the top half of the board

[Splave]

Looking great man only a matter of time now before it passes

[bullant]

Testing one of two Pentiums I bought a little while ago,first time testing this cpu on cold and with cold memory's

This run was no waza



This run was with waza,will have to try a smaller waza later as i think the one I was using was a little to big



Tried a 5Ghz run but by this time was getting little unstable,was looking ok thinking if this passed 56.3xx

[Splave]

hehe g3258s are really fun imcs

[bullant]

hehe g3258s are really fun imcs

They are fun man,not sure if this is strongest imc on this little fella but its ok,thanks for the few tips man ,still trying to dial in

Final got some passes on the little Pentium ,will try push bit more later

[bullant]

Little more

[Luumi]

Not the best effieciency there. LN2 next week, let's see how my cpu and 2500 vipers do. How cold do you guys run your PSC btw?

[Punk Sods]

Hi there.

I have a little problem. Although this is the first 4770K / 4790K CPU, I got it stable under water cooling at 5 GHz, but anything higher clock is very unstable, particularly at low input voltage. I can increase VCore up to the stop does nothing.

Example: XTU @ 5 GHz - 4790K:
http://hwbot.org/submission/2603052_

LLC level changes doing nothing, just increase the input voltage, maximum everything is about 5 GHz only superpi stable.

Does anyone here have an idea what I could try?

[Luumi]

Getting 5ghz xtu stable means your cpu is really nice. For example I can pass cinebench at 4.9 with 1.34v, but 5 will not pass stable no matter what I try, not even with 1.47v. 5 and over are really hard and rare for haswell on water mate.

[Punk Sods]

Yes, I also think that this is so.

But perhaps there is still a trick I do not know yet.


greeting
