7970 volt Oc problems

[Mal X]

Sorry to hear. I take it you followed the OC threads first?

hi

yea i actually backed off the OC two days before it blew, plus i hadn't gamed for two days either..... it was at 1.24.....2200.....1680, the card blew as i just finished reinstalling Win 7 from scratch.

i'm very upset about it, if this happens again i'll switch back to Nvidia, i dont expect a premium card to blow, especially when i've spent 370 quid, after all; it's supposed to be OC and much higher than mine..in addition, my card never crashed whilst gaming

i only hit 1.3 V for about 5 mins in Afterburner, i reverted back to 1.25, but strangely enough although the card didn't crash, i could sense it was struggling, the coil whine was too loud for my liking, i , this spooked me quite a lot !!!!

do you remember when i only fitted one 8pin plug ?... well i read that this damages the card, so this might have been what blew it.

my GT 8800 was OCed much harder than this and lasted 6 years, so this why i'm extremely unhappy right now.

on my next card i'll not go above 1.20v......1200......1600, it's not worth the hastle mate, i dont trust the card one bit..... not after this.

i could not send the card back to them, they collected it today instead, which is quite nice i suppose. if they give me an option over the RMA, i'll ask them to send me the 670 straight away.... DEFFO !!!!!

i'm extremely pizzed off with AMD right now, plus the people that uploaded win 7 for me, and were too bloody stupid to realise that all the stuff imported from my old rig was WIN XP, it's ok for me to make this mistake.... but not them because they're the experts, i was running Steam via WIN XP..... rather than WIN 7, plus in 32 bit mode

i mean the compatability mode was either WIN XP, or Vista.... it would not work on Win 7 ( Bioshock), i had to download a software that altered the gaming files/ ram, just to get it to work.... i also couldn't play Borderlands, all of these files are now gone for good

Win 7 is now miles faster and runs glitch free, so i'm happy with this, but before i reupload STEAM i'm going to check that it's perfect first

The VTX 7970 X-edition has increased voltage already. It also uses a stock OEM board so you may find with the factory overclock and increased voltage you might be at the cards voltage limit. Have you tried overclocking without increasing the voltage ? Mine runs happily at 1200/1500 on stock volts.

A decent 550W psu will run a 7970 system with ease, My OCZ 550W with dual 25A +12v rails had no problem. For crossfire a decent 750W would be best. Make sure the PSU has a decent +12V line, most decent branded ones will. Don't worry too much about efficiency ratings its marketing bluff. You save a few quid a year and is not worth worrying about.

Your Akasa PSU has dual 18A +12v rails which for a high end gaming card is not ideal and is likely why you are not getting the best from the card.

yes, i would be extremely careful about OCing the 7970 too far, i get quite scared reading that MSI Lightning thread, these guys could be walking into trouble, i would suggest something like 1.2.......1900.......1600.

you can go to 1.3v yes, and i did too, but you dont know if this damages your card do you.... because something did !

the only thing i avoided was to oc the CPU, i could not find the correct figures to manually adjust it to 4.6 and i put up quite a few posts... so i settled for 4.4 which is fine.

i would not risk a manual adjustment without all the figures, because i tried this and when the pc crashed it lost the Win 7 files..... basically the mobo is set to 1.5V, this is way too high, you have to reduce this to 1.3V plus to increase from 150 to 200 in two others, but without being 100% sure it's not worth the hastle.

The card didn't "blow" because you put 1.24v through it, it blew either because of a fault from manufacture or from your doing. There was a whole thread where a lot of folks tried to help you including myself, and we suggested that you do more research before overclocking because you were obviously struggling. This is no fault of AMD, they only designed the gpu and you're lucky you could go over 1200mhz on such low voltage IMO. Your next card, either a 7970 or 670 could be a worse clocker due to the luck of the silicone lottery.

maybe, but the card should be able to OC without blowing, simply because that's what it's advertised to do, AFTER ALL, the GT 8800 had no problem whatsoever.... it was a very strong card, this one definitely isn't....it's weak/unreliable in comparison

i did not put any extreme figures into it, i started low and went high and it never crashed once, i never went above 1.3......2200.....1860.

finally, the image quality is no better than the GT8800, it's only much faster, i dont notice DX11 or any of that fancy stuff, Borderlands looks exactly the same...... the new rig is only much faster, that's all !!!!!

Lol you overclocked your 7970 to; lay borderlands? Was 200 fps not enough or something?

 

[Gregster]

You ran the card with only 1 x 8 pin connector?

 

[dave_beast]

You ran the card with only 1 x 8 pin connector?

I would doing assume doing that would damage a cap on the power supply circuit which would cause the cards failure.

 

[psychodil]

Usually a card beeps and shows a warning on screen if you don't connect both power connectors. I doubt he got to 1200mhz with only one connector even if he got it into windows.

Sounds likely to me

I have never tried a card with only 1 connector (where 2 are required that is), so no idea what happens TBH.

 

[MOOGLEYS]

If I just connect the 8 pin on my 7970 I get a message telling me to check the power connectors and a beeping noise. It does not boot any further ?

yes i did, dont you remember taking the pizz out of me the power cable i fitted only had an 8pin on it, the other one upstairs had the additional 6 pin on it, so this was a bit of a **** up, my pc doesn't bleep; no idea why.

but the monitor didn't work ``no signal`` it only worked once the other 6 pin socket was inserted, even so; according to the web i was lucky not to blow the card right then, this tells me it was fatally damaged from then on..... in total the card only lasted about 7 hours after this, i played Borderlands for 2 hours, and Bioshock for about 3 hours and then i got so fed up with Steam that i started deleting the files and reuploading Win 7.... the card wasn't working when i brought it here to update the software early the next morning.... i thought ``what the hell is this, NO SIGNAL and the keyboard is dead, why the hell is the keyboard dead``.

the dead keyboard scared me the most !

I don't think AMD cards boot unless both are connected (if two are required). My HD 6870 didn't.

@Mal - forgetting a cable into the card will do it no damage at all. It just won't start up.

 

[Mal X]

pc still needs updating, i havent touched it since then, i've just brought loads of new stuff for it that's arriving tomorrow, so i'm going to be stripping it down again..

yea it didn't boot at all, but the keyboard still worked, and this is why when i saw no signs of life from the keyboard last thursday that i suddenly went pale as a ghost..... i thought the mobo was dead, but no thank God that's ok, the mobo is quite strong it's survived quite a few knocks

i've never had a mobo die, only cards plus a few PSUs

I'm really looking forward to seeing some crazy overclocks on the msi lightnings, under water that is. I know some people here have bought them just for that purpose

1450 mhz core clock will be my guess ...

imagine two in cfx underwater clocked to the max....that computational performance!

i'm looking forward to seeing the 7990 something tells me i havent finished upgrading yet !!!!

As likely to go as high on a reference card under water. (i.e. extremely unlikely). The card would need too much voltage.

The lightnings are as likely to reach high overclocks as reference cards and all the spiel around them is marketing stuff only.

Plus they only come with single link DVI which would make me look elsewhere even if they did have a higher chance to get a good overclock.

 

[windheaven]

is it worth buying one of these? back up UPS

fail

Wrong topic windheaven....
