I figured given that there are more of these cards available that I would do a write up of sorts. Firstly, let's get the important stuff out of the way.

There is no such thing as a 6970 TFIII. There is such a thing as a 6950 TFIII, so with the £269 bargain you are getting a Lightning card.

Here is what you get.

Be warned, they are enormous. The card measures in excess of 31cm. They are also very tall, which is down to the PCB (will cover that shortly). If you wanted a better idea of how big they are, here is a pic of the card sitting next to a 6970 stock card.

The size of the card is pretty much dictated by the PCB. This ain't no ordinary PCB, it's a completely custom PCB.

msi_6970l_26.jpg


Every single last part of this card has been designed by MSI from the ground up. Even if you didn't want to overclock the card or push it above the 880mhz clock it arrives at it doesn't matter. The chokes, caps, and every other IC is military grade.

On the PCB there are three voltage probe sockets. Each of these can be accessed with the probes supplied in the box. To find them you need to remove the foam and there is a hidden compartment underneath. In there you will find them, a mini adapter and a Crossfire bridge. Also included is a Lightning manual and a Lightning install DVD.

Obviously as usual you want to ignore the drivers, but there is a very good version of Kombustor on there. It's different to any other one I have seen, because it alternates between about ten different tests to make sure you card is 100% stable. It also plays a really funny 1980s cheesy porn song as you go, which can alleviate the stress when your PC locks up because you didn't get the overclock right :D

If you wanted to know just how hard MSI had worked to change the 6970L into a whole new animal here is a stock 6970 PCB.

Looks a bit, well, poo doesn't it? Once you have fitted the card (and please make sure it will fit !) it looks a bit like this.

Overclocking.

I spent the evening overclocking and testing the stability of the card. Apparently in reviews of the "actual" Lightning the card will do around 1035mhz with 1.3v. I did manage to get mine there, and stable, but I needed 1.35v. I also noticed that in certain benchmarks (like 3DMark 11) the card was throttling.

Now on the back of the card there is a switch. MSI give it a funny name, but apparently it removes the throttle. Sadly my card is not a review unit and nor do I intend to blow it up playing with it, so in the end after hours of testing I worked out that the sweet spot for the card was 960mhz and 1.25v.

As I said, this won't be a typical review because this is my card and I intend to use it. It needs to be able to maintain the clocks I give it, and safely. You will note on there that the top temp of the card today was 70c. I have my case fans set to 2% (Deltas, very noisy) and my heating is on. The 70c occurred during a three hour Battlefield 3 session, with fans on the card set to acceptable levels.

Here is a 3Dmark 11 score with the above overclocks.

3dm11960.jpg


Battlefield 3 performance? Well, at stock 880mhz clocks (these are going to be actual real world figures) and with FRAPS running the lowest I saw them go to was 38 FPS. This was during the raid in Iran (night time one in single player). However, when the card was set to 960/1.25 which took mere seconds I never saw it dip below 44 FPS. And I haven't since either (I am now up to the stupid bit on the train platform where you play SIMON).

Which seems to disagree with scores taken from reviews of the 6970L, but they do not point out what level they are playing on nor if it is MP. So given that mine explains exactly what you can expect I would find it a tad more useful than a pile of charts.

Noise from the card is acceptable. I won't say that you can't hear them but it's a tolerable noise. It has a nice reassuring whoosh, unlike those horrid blower fans that sound hollow and annoying.

Performance of the card when overclocked is pretty much on par with a STOCK 580. It won't set the world alight, but it's more than man enough to play anything I have given it at 1080p. Obviously the card isn't going to be any good at any resolution over 1080p (well, aside from 1900x1200) so that puts it right in the same category as a 580, given that it too isn't man enough for 1600p. At those levels you are going to need a 590 or 6990.

The last bit.

Basically at the price OCUK are charging for this card it has no direct competition. Yes yes, a heavily overclocked 570 will beat it, as will a 580. However, what the Lightning does have is lots of Vram. The kind of levels of Vram that you would need to spend a pretty penny to get with either a 570 or 580. Three months ago if you'd told me that I needed 2gb of Vram I would have pointed at you and laughed, but alas, with the way gaming is headed now it is the most important part of any GPU purchase, AMD or Nvidia. It doesn't matter how much brute force your GPU itself has, without the Vram you are in trouble.

I am fully aware that you can get a 570 that would possibly even be cheaper than the 6970L, but the bottom line is the 6970L is not a normal card. It is, to all intents and purposes, a work of art.

You are getting a custom PCB that was designed specifically for this card. You are getting top quality top shelf components. You are getting every single overclocking tool and accessory you could throw a stick at. And that is what separates this card from every other card on the market.

Usually when MSI built Lightning cards they gave them a price to suit. And that pretty much priced normal people out of owning one, which is a shame.

I can't tell you how much drool accumulated on my carpet from staring at photos of the 480 Lightning fondly, but alas, it was just too expensive for me.

The deal OCUK have going on here is quite remarkable. Not only does it make owning a Lightning affordable, but it makes sense in other aspects too. When you cost in what comes with the card this actually works out cheaper than a stock 6970. So if you were in the market for a 6970? this really ought to be a no brainer.

So yes. It's not the fastest card in the world. It is ideal for 1080p and nothing more, but it will last you for years.
 
It is a Lightning.

They're just clocked to 880mhz as mine would'nt do 940 at stock volts (1175mv) or 1.175v.

Which doesn't matter, because mine does 960 @ 1.25v.

So yes, it has the switches. I mentioned them in the write up, basically one of them disables the throttle allowing the 1035mhz I got at 1.35v to stretch its legs.

I was a coward though :D

960 is more than fast enough.
 
Did you put the power controls in the CCC to +20% when you overclocked?

Thanks for taking the time to post this review btw, always interesting to see how people get on with their hardware.

I turned it off completely. But yes, it was definitely causing crap. Might still be tbh.
 
It's as loud as it always is mate. I have it to whack the fans to 100% as soon as it hits 60c. I don't like a card going over 80c, that's when damage is caused.

I have a Turtle Beach HPA2 surround headset. It's loud. When I game it goes on.

It's the same cooler as the 6950. It just has a completely custom board and power stages ETC.

TBH the overclock hasn't affected the temps at all. It's constantly warm in my room due to me having 100% wool carpet and 20mm double glazing, so the temps are no different from stock to OC.

The fan profile is up to you I guess, but yeah, this is a performance part so there are parts of it you are going to have to live with regardless.
 
There's always RMA of course, but I have a conscience :D

Thing is there's utterly no point in pushing it to the brink of destruction any way, as I tend to break the mould. I like to, you know? actually use my card and enjoy playing games with my pals :D

An extra 5 FPS really doesn't bother me all that much. The card does what it needs to at 880 tbh, the 960 thing? just a bonus for buying a special card :)
 
That would explain it, cheers Gibbo !

It could be a case of over production I guess.. Not surprising it's happened before (480 L).

I mean they came up with the 480 L which is a legend. Sadly they came up with it about ten seconds before the 580 came out and people panic bought the 580.

Which was daft really. The 480L was able to absolutely destroy a 580 when in the right hands. It still holds the single GPU world record IIRC.
 
I bought the Sapphine over the MSI because of the price difference $110 (£65). Using Trixx or afterburner mine sits at 980 core 1480 mem @ 1.275v and never misses a beat.

(But still only gets 45fps BF3, 1080p on high :confused: )

Yeah doesn't surprise me really. It's a poor engine. Well, it looks nice, but it needs work. See also - Crysis. No point throwing money at it because you're really just pouring perfume on a pig.
 
Yeah sorry man, I forgot the pitfalls of having warm air in space :D

So long as it doesn't affect what's important (CPU temp, NB temp) then how is it a problem? What exactly is the horrible downfall from having warm air being in your case?

And of course, no one has exhaust fans on their PC :D

Sorry man, not being sarcy, but I just don't see any basis for the "But it dumps hot air in your case !". It hasn't affected my Noctua NH at all and I have been using those coolers for years now as I can't stand that horrible noise blower coolers make.
 
Just an FYI to the op the reference 6970 pcb is this version:

http://hw-lab.com/_old/hardware/videocards/amd-cayman/amd-hd6900-pcb-v1_x800.jpg

The linked one appears to be the v2 which used "cheaper components" according to most .

If you google the stock code it will take you to the stock 6970.

These are REBOXED Lightning cards. No one else has them apart from OCUK because it's a deal OCUK struck up with MSI.

So if you go to MSI's website all you will find is either a stock 6970 or the 6970 Lightning, which is what this card is.


Can anyone confirm which one i will receive as i want the twin frozr version as red will not match my build.

It's a TF III because that is the cooler the Lightning uses.
 
Send it back not as described.

The pics on the listing show the lighting. You can clearly see it written on the PCB.
 
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'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.
 
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 :) )
 
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.
 
Well yeah the 7970 is faster, but it costs it too.

And it's not like it has made cards that can, you know? run any game irrelevant.

This card is still a bloody bargain IMO and I certainly don't regret buying mine. Especially given that the cooler on the 7970 is obscenely loud.
 
LOL

Try BF3 at 3560x1920 all Ultra Settings with 4xAA and then come back and say it can play everything.

For reference my HD6970 pulls around 5fps at that setting AND runs out of memory....

Great card for the money though.

That's because it's a 1080p card.

Anything more than that ATM and you need dual GPU. This is why the 7970 will come in very handy for larger resolutions, but I feel will be wasted at 1080p given that there are several cards that can run anything on the market at 1080p :)
