OCUK 6970 TFIII (Lightning) review.

Well if i get the wrong card thats what i will do but with christmas arriving how would i stand with the dsr limit of 7 days.

7 working days so you don't count weekends and Bank Holidays.

And you don't have to return the item you only have to notify the seller within 7 working days that you're returning it.
 
So i got my 2 cards today for my new build and they look superb! Didn't get the Dirt 3 games (or vouchers) with either card, but after some chasing i've been told they will post them out. No big deal i guess.

I was in the market for a pair of 6970's and happened to come across these by chance. I was never going to over clock any 6970 i purchased, but having come across these i am so tempted!!

I have a few questions that i hope somebody could help me solve:
1) Why does it have a 'silence' and 'performance' switch? There is nothing in the manual that tells me what it would be used for:

2) How could i make best use of these switches to overclock my cards to the max stable settings? I have checked the manual for these switches also, but nothing there?!:

Hope to hear from someone soon! :o)
 
tempted by this card as it looks quite shiny :\

but then will I really see much benefit over a hd6870 at 1920 x 1080.
arg the temptation.

keep telling myself I should just wait and see what the 7000 series offers.
 
6870 was never a high end card. Was more a mid range stop gap before the 69xx.

Can your 6870 play everything at ultra with 4xFSAA? because the 6970 can.

i put BF3 to the max and i think it went at less than 1fps
it was like 1 frame every five seconds lol.

although i'm now playing BF3 less than I was and nothing else is pushing it anyway.
will no doubt just be older games i play while i wait for Diablo.

So i'm sure i can wait.. and just spend the money on a new case instead :)
 
I've only heard one complaint so far and it could have been a genuine mistake.

In the description it now says -

Features:-
- Same PCB / Components as Lightning Version
- Huge overclocking potential (1000MHz+ Core possible though not guaranteed)
- Near Silent Operation
- Core Clock: 880MHz
- Memory: 2048MB GDDR5
- Memory Clock: 5500MHz (Effective)
- Memory Bandwidth: 176GB/sec
- Processing Cores: 1536

ETC. So yeah, either he ordered the wrong card or it was a mistake.
 
Nice review. You think I will be ok with a Corsair 750TX PSU? Got a Phenom II (clocked), 8GB RAM and 1 SSD / 2 mechanical HD's.

I take it these are very likely to be able to be clocked to the same settings you have?
 
I use an 875w Alienware 80+ silver psu. It's made by Newton Labs (same company who made their old 1200w units).

I would say your Corsair TX is every bit as good, as it seems Alienware told a few porkies about the 80+ figures (they're not official nor on the 80+ org website).

They will clock well. Mine? the problem with it was it would not do 940mhz @ 1175mv (stock volts). At which point it's not Lightning spec.

However, do bear in mind that even with the safety switch on you have up to 13500mv at your overclocking disposal to find a nice high clock that is stable.

Me? After a few hours of fiddling I found that 960mhz @ 1250mv was totally stable. And it is, it's been set to that since I did all the testing and I've gamed my nuts off this past week :D Completed Borderlands (took 11 hours) got about half way through the single player campaign on BF3 and a good chunk of time into Skyrim too :) )
 
ALXAndy, just wondering how you tested the stability of your card? Is there a guide i could follow? How did you know the card was unstable, and what does the card do, that makes you aware it is throttling?

Thanks!
 
Included with it is a copy of a Lighting install DVD. On there you will find a good version of Kombustor. I'm sure I mentioned it in the review sort of thing, it plays cheesy 80s porn music :D

Thing is it's actually very good, because it goes from thrashing the core to thrashing lots of other aspects of the card (RAM, different ways of drawing ETC).

So I guess if you get out of that alive you can safely assume your card is stable :D
 
Haha you'll soon know mate :D

Your PC will just lock up, and you will get lovely sharded graphics all over the screen :D

The way you will note it throttling is when you score 4500 in 3dmark 11 @ 1035mhz when you scored 6000 @ 960mhz, yet it runs through fine.
