Sapphire 100311-2SR Radeon HD6970 (970/1475 stock volts!) - Page 4

post #31 of 77
breen, yes... it's the same PCB. It's the new reference refresh.

People get really pissed because there's an inductor/phase missing... but we need to understand this pcb ... i didn't have the time to examine... need to check what mosfet's they are using ...

I can't understand those 2 smaller inductors ( the R47s ) ...

One thing is sure... they're are not volterra... ( sadly ... )

Texas Instruments, right? Isn't that the reason for the the whole initial delay? They had to switch to Volterra last minute because Texas Instruments wasn't ready? Now they have the TI parts. http://vr-zone.com/articles/amd-rade...med/10276.html

I know nothing about the difference between Volterra and TI. I'm assuming based on this that Volterra is better.

so whats the conclusion that the black pcb board (reference 6970 sapphire) is better than the blue pcb.. the one with the lock..?!

L3... trying to understand that ... can't find much information about it ...
I can't say it's worst or better...

I don't judge the card due to having 1 less inductor... i mean ... what' makes me confused is that the mosfet and the cap are there... only the inductor is missing ( 1 phase is composed by the mosfet, inductor and cap ... ) ...

At the same time, those 2 small R47's inductors are there for a reason ... can't say why yet ...

true but... I have heard that it is a better cooler and that it can overclock better... I just put my reference 6970 to 950 core 1500 memory on stock voltage stable on heaven benchmark 2.5 and furmark... How does that hold up to some of the stock voltage Overclocks on the BLUE pcb board... I am very happy with my black pcb reference card as... My best friend has a revision one with the lock and that FAN gets LOUD and sounds like a whining turbo out of a jet... I find that the reviews are completley backwards as i have 2 6970 references and 1 6970 revision to compare to for sound I cant see how it operates compared to mine because its my friends card but I have heard it at 100 percent fan compared to mine and I take the reference fan any day... I think Id have to have a 150 percent Fan to catch the 100 percent revision sound.

I have a reference and non-reference sapphire on my PC, you can see them here:

http://www.overclock.net/12679364-post198.html

I can guarantee that the non-reference card Overclocks a lot better and it is A LOT quieter

So don't come and tell me the reference card is quieter, because it is completely wrong.

To keep both of my cards below 70ºC I have my fans set at 50%.

A reference card at 40% is as loud as the non-reference card at 50%

I haven't played much with overclocks yet, but I agree on the whining aspect of the sound. Once you get to 24%, you hear the whine. It kind of goes away or you just can't hear it as the fan speeds up to 30%. On overall volume though, my only frame of referent is a reference built by ari 4870x2 that I just took out. I had it set to default in ccc, so the max was 50%. It seemed like it was quieter than this sapphire card. However, it also idled around 80c between the two gpus.

Just because you got a good revision card doesn't mean that all revision cards are going to be better... Im telling the truth.. My reference card is quieter than the blue pcb board by alot... the BLUE PCB SOUNDS LIKE A JET and my reference sounds like a low tone fan.. Id much wrather not have a whine.. But overclocking I wouldn't know. Trying to figure that out.. I thought I was stable at stock voltage 950 core 1500 memory but GPU TOOL pics up errors... can this be resolved by upping the voltage? or does artifacting only have to do with heat...

that statement of 40 percent to 50 percent fan speed doesnt work for me bud... My reference fan doesnt get audible until 54 percent... So i dont know where you are basing your hearing off of rofl...

Sorry, but you're completely wrong.

Either your friend has a faulty card, or you have a magical reference card....

But all the black cooleer HD6970's are a lot quieter than reference cards, now wether you want to believe it or not, I don't care, but that's the truth and everyone that has it can tell you.

Then you have some serious ear problems... The reference card is totally audible from 32% fan speed at least in my PC, now I may have ultra sensitive ears.. But I can't stand any of the graphic cards above 45%

Now your statement doesn't work for me either, 54%? Are you serious?...

haha... Quieter to what extent.. at 24 percent fan speed I PROMISE YOU if you put your reference to 100 percent and your revision to 100 percent the revision card will get to you first with that WHINE sthat sounds like a 747...


I have no need to lie im just trying to get people out there to know that the Reference cards arent as loud as you and a couple people make them out to be.. I have 3 6970s to compare from 2 reference and 1 revision with the lock.. and even my friend was like yea no my fan is "way louder but that means it has to cool better "
