Never Watercool XFX HD7970 -> problem...

post #1 of 59
Thread Starter 
So... finally I managed to fit a waterblock onto the XFX piece of crap card (soz for being so annoyed at them, but they literally wasted £400 of mine, when I should just gotta an asus reference card)...

For those who have no clue about what I'm talk about, let me give you a quick summary: few months ago the XFX HD7970 Black Edition Double Dissipation, used to use a reference PCB from AMD -> i.e. you would have been able to water-cool them. So I thought since they were being sold quite cheap, to get one of them and then overclock it to basically a GHz edition standard. Guess what?! XFX being they dicks they are, decided to change the PCB without warning anyone... even EKB's configurator was wrong.. So my waterblock would not fit on. After modding the waterblock and adding some passive ramsinks, I somehow managed to pull it all together!! LUCKY ME...

You would now wonder what my problem is... Well! I tried to overclock the card, and it seems like it wouldn't budge over its stock clocks, it would just immediately get artifacts and die. Now you may say I would have fitted the water block on badly.. but my temps barely go over 40 degrees, after like many hours of usage and even after raising the clocks. First problem: Any idea on how to actually overclock this card?

(on a side note, I suspect the reason XFX did the PCB switch, was so that they can lock the voltages/clocks, and purposely stop people from overclocking the card -> so we would get more expensive cards with higher clocks, but that's just me thinking XFX are dicks...)

But now an even more annoying and worrying problem is occurring.. AT STOCK CLOCKS, I've seen some very quick flashes of artifacts in-game, though small and barely noticeable, I have noticed them and it angers me. Any ideas on why this card is being such a nuisance? ;(

(Sorry for the hate on XFX, but so far my experience is that they aren't a very good company for the overclockers and watercoolers of the pcb world -> the warranty is broken even if you open the card up >.> )

Have you check your vram temps after the mod?

XFX still honors warranty if you open up the card. The thing is you have to tell them that it's running too hot and you want to open it up and change the thermal paste. They will let you, it's better than them having to fix it and ship it back to you themselves. I've done this on about 4 XFX cards I've owned. Just shoot them an email, explain whats going on, you might even be able to tell them you want to add a waterblock. They just dont want people that don't know any better to get in there and start poking around.

So how about putting up a couple of pictures and a thread title that other users can search for, so that it doesn't happen to others.

There was actually stuff about this on EK a while ago.

Well, I've already talked to XFX about it, and they said that for their newer cards, they quote "will not" allowed for people to open up the cards. So... all I gain from this is that I shall never be getting any more XFX cards for watercooling... and/or since their card can barely be overclocked, I will probably never buy from them again. And about the temps on vram, unless I get a infrared heat detector, I'm not gonna be able to do that. All I know is that the heat-sinks I applied to the vram, provides much better cooling than the stock -> on the stock they even left the inductors uncovered....

This is an end user problem. You should have done research. It's been made public that XFX started shipping revised boards since March/April. The first threads announcing this were on XS. Then EK announced it on their on page and yet you still went for it when EK said that it won't work.

"made public" Ha LoL. I know now after ages of searching that it was "made public" ... but how was I meant to find out about it when it was not very well publicized at the time I purchased the product. When I was doing my research, I checked tons of reviews from many websites, even EK's configurator - (NOTE: it may have been possible that there was a message posted on EK's WEBSITE which I wouldn't have seen as I do not constantly follow EK (it was an old messages from June 2012 so I wouldn't have been able to see it at that time), nevertheless EK's CONFIGURATOR STILL said that it would work around October), but nothing about this PCB switch came up when I was researching then - i.e. nothing came up on the first few pages of Google. You can't expect me to have some sort of pre-existing knowledge about this change, I can only find out about it, if I can look it up somewhat easily. Unless you want me to literally go through every search/page on Google, I'd say XFX should have actually PUBLICIZED it well. But w/e dude, blame it on me then tongue.gif

I dunno. It does suck big time that for you it didn't work out. But when I did a google search for xfx 7970 black edition reference PCB the first google result I got was this:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CDMQFjAA&url=http%3A%2F%2Fwww.xtremesystems.org%2Fforums%2Fshowthread.php%3F282682-XFX-7970-Black-Edition-DD-New-PCB-Released&ei=Qk4NUbfyMsvliwK2sYHYDA&usg=AFQjCNHAY6ye0Ppg8eh66s_mrawibfupLg&bvm=bv.41867550,d.cGE

And that was dated august 27th so there was information out there about it. But like you said EK should include on their cooling configurator website the fact that new revisions are no longer compatible.

I'm just wondering if anyone knows about any BIOs hack which will allow me to access the voltage control/stabilize the card?
