My new toy arrived this morning! When I saw it on today only for £439.99 I snapped one up quick. I was tempted to get two, but not until I know there will be a full cover waterblock.

But shame on ocuk! That's 2 orders in a row with no haribo. WTF?

The aesthetics of the card are excellent, imo. Those of you with 90/180 degree motherboards are gonna love it too. In these pics it looks a dull dark greyish colour, but that's just my rubbish iphone camera. The metalwork is jet black.

MSI: put those nice shiny 'msi' stickers on the fan hubs you numpties.

Here it is next to the whiny annoying wimp it's replacing.
I didn't realise from the pics I'd seen that it was so big, especially the width.
Fits with acres to spare in my 600t though.
Length wise it is roughly half a centimeter longer than the width of an E-ATX board.

I bought the phantom for aesthetics and quietness. It delivered on neither. I paid a lot for it too. Oh well, live and learn.
The side view is the second worst part of the Phantom. Those struts and the shroud are plastic, and it shows. The lightning looks the dogs. The rubbish iphone camera doesn't show it too well, but the nickel plated heatpipe isn't dirty-looking, it's.. nickley. Nice industrial-looking design from the side. My only gripe is that the side of the pcb isn't black. Although.. Idk if I've eveer sen a pcb that's coloured on the sides.

And this is where it REALLY trumps the phantom.
Words can't describe how ugly that brown pcb is. Brown. BROWN. This isn't 1997, Palit.
The GPU 'reactor core'? I'm sceptical. I bet it's useful if you're chucking silly volts through this under LN2 or w/e and chasing world records, but it's probably not going to help me on air (or hopefully water) and it certainly isn't doing anything on stock volts.

The stickers do my nut in though. I'm sure MSI's warranty doesn't transfer to 2nd hand owners, so they should've put the yellow warning (about improper installation of the reactor core) as a peel-off label on top of the thing itself. Then that white serial number sticker, that should be on the damn PCB, or underside of the backplate, with a matching one on the inside of the product box. The tiny coloured stickers.. I have no idea what they are about yet, but they irritate me greatly. They say 01 ok, 02 ok ,03 ok. So clearly useless, and not even straight!.
I'm going to read my warranty right away and see which of these I can tear off.

No pics of it in my system yet sorry. I have an embarrassing watercooling situation ^_^. But to describe it:
There are two blue LEDs in the fans, not crazy bright like the disco jetstream, very dim infact. The light is not visible elsewhere in the case. The reactor core with MSI logo lights up blue, again very dimly. There are a series of LEDS relating to power stages, or something like that (I haven't read the manual). On the stock bios these LEDs are blue, this time they are quite bright, but they are very small, they don't chuck too much light out. When you flick to the overclocking bios I believe these glow red. Sitting on desktop now there's only 4 lit up, during stress, more :).

The card fits my black/white theme very well, but it clashes with my motherboard (maximus iv extreme-z). Tbh though if my usb 3 stops working and I have to waste even more time getting it to work again I'm just going to sell it and buy a z77, probably an msi in black/blue.

The bit everyone is interested in:
Overclocking.

I haven't had enough time yet, I spent most of today sneezing, snorting and blowing my nose, while trying to re-do my cable management.
This is what I have for you atm:

Stock Bios.
Note:
Power limit makes 0 difference on stock volts. My power has never gone above 76% in the benching I have done so far (Heaven 3.0). I even set my max overclock to a power target of 80 and got the same result.
Everything is on the stock fan profile too. It's pretty warm in here tbh. Max temp I saw was 62c but it generally hanged at 61c.

Out of the box - Core 1110mhz, Boost 1202mhz, Mem 6010mhz
Max core overclock - Core 1110 Boost 1267mhz (momentary peaks of 1275), Mem 6010mhz

So core on stock volts is a max of +65. not bad I guess. Now I have noticed that the peak voltage was 1.187, which I believe was probably during the time it boosted to 1275. Or that could be a bug in afterburner, because I though gpu boost worked in 13mhz increments, which would mean it would boost to 1280? Whether the voltage was real or not, I need more to go over 1267, because +66 gives me a CTD on 1.175.

I'm going to start on the memory tomorrow. This is my first go with 600 series so any pointers? I've read I might have to drop the core to reach higher with the memory. Honestly I'm not sure how high to aim. I moved the slider thinking it would be a small increment and it was a +100 jump. (Baring in mind I'm coming from a 580 that would CTD from heaven with *any* overclock on the memory).

My plan is to see how far it will go while stock, then add more volts (If possible without the 2nd bios. Again, I need to read the manual, lol) and take it to the raggedy edge. Then I can flip to the 2nd bios and do the same again.

Any questions about it, fire 'em off. I'll see what I can do.

Anyone else playing with one yet?

2 things strike me about this card...

1) Doesn't that blue 'reactor core' stick up from the back of the card a bit? Would this interfere with SLI setups?

2) The black plastic of the fan 'shroud' seem to overhang the SLI bridge tabs. How would you connect a 3 or 4 way SLI bridge?
 
I played late last night lol, So here's what I have so far.

Any way to volt over 1.175?

So far I have only used the stock bios. Moving the voltage slider does nothing. Voltage was still 1.175. I have read elsewhere that OC bios allows overvoltage (although I don't know if afterburner supports this yet). I'm going to do this today.

is it quiet under load?

My max OC on 1.175 is +65 1267mhz, +590 7192mhz, fan completely stock. I loaded up BF3 on ultra 1080p, and had to off all my case fans to let some heat build in the case / to try and hear it, LOL. I didn't mess long though because that's unrealistic, only about 2 minutes. Still, max temp was 62c max fan speed 42.
At these stock volts it's incredibly quiet. A real treat after the phantom. This is on my desk right next to me BTW. It's not silent, but I had to shut my windows, turn off all the case fans in order to hear it (I run them very low anyway).

The reactor core sticks up approx 1cm ~11mm by my eye. It will not interfere on my board
[google maximus iv ex-z images]
SLI for me is red slots 1 and 3.
Now if your board runs them in the equivalent of red slots 1 and 2 you're going to have to remove the core on the bottom card. From what I've seen so far it does nothing on stock volts because my oc isn't spectacular.

It's actually a metal shroud. There's no plastic anywhere but the reactor core. You cannot use one of those solid sli connectors with this card. You do get an extra long single flexy SLI cable with the card though, and it's fully black with a white MSI print.

Much jelly, this is my card to be very soon :D

Does it have led's on the underside of the card through the back plate?

Not really sure what you mean. There's a single blue led in between each fan and the pcb which points out of the case. then for the back plate (pic 4 above) if you see the two cutouts with the indentation, they are the first of the LEDs, the others are from there towards the end of the card.

Today while testing for quietness I did notice a very slight coil whine with my case door on it's inaudible, with fans on it's inaudbile. The only time I have heard loud coil whine is during the exit screen from heaven @ 5200 fps.

Could have sworn somebody told me this was 2x6 pin o.O

Cant wait to see some results after they released 2.2.3 afterburner.
 
you need to switch to the 2nd bios and be using afterburner 2.2.3 apparently, then you get voltage control (posts from late june indicate this was supposed to be out already, but it's not available for download as far as I can tell)
 
Sounds like Tri-SLI/Quad-SLI might be a no-go on that one then. This is what put me off this card/cooler.

Looks nice though.

Yea. it's two slot but the reactor sits up. it's not necessary but I haven't tested whether it makes a difference yet.

Well, the ocuk description says 2x 6 pin but it is 2x8.

well i started afterburner after downloading the latest and it told me a new version was available, 2.2.2.

Anyways, using 2.2.2 I just did a quick test. Firstly, on the overclocking bios the lights are still blue, so idk where i heard red from. maybe that's 7970 version? idk.
Anyways, enable the oc bios and you gotta know what you're doing, lol. I can currently add a max of +100 mV to the core. Max power limit is 200%. The highest you can set the core is +549, memory +1000, lol.

So yes, i can confirm that this card will exceed 1.175 volts on the core. as a quick test i left mem at stock, put power at 200% (just for ****sngigs), +80 on the core (+65 is my max oc on 1.175) and added 50mV. I didn't thoroughly test this as in "ineed these volts for this clock", just a quick test.
Afterburner reported a max voltage of 1.212 and it was stable in heaven.

I have heard that afterburner 2.2.3 will allow even more voltage, but maybe that's speculation?
 
I think judging by my max oc of +65 1267mhz on 1.175 we can safely say I have not really won the lottery on this one. I predict just shy of 1400mhz if extra volts come from 2.2.3. Scratch that. probably mid 1300mhz range tbh.

But it does show you - unless you can apply more volts, all these bells and whistles on other cards are useless. The lightning is full of custom components yet on stock volts it wont exceed a reference massively, and will be just beaten by some.
We all knew this, but nice to confirm.

It's on offer again @ £449. Definitely the best 680 on ocuk imo.

A small update. It seems in my 'excitement' at discovering the voltage control earlier i didn't realise that 1.175v + 50mv is not 1.212 LOL.

The voltage adjustment doesn't work yet. Setting the card to the oc bios just sets the max voltage to 1.212 as standard atm.

Also, for the life of me i can't work out why when heaven benching at +116 ~1320mhz, +595 ~7200mhz which is max oc(raggedy edge for the core on 1.212) my score is lower than on +65 + 595 on stock volts.

Guess I'm waiting for afterburner 2.2.3 then!
 
My 680 doesn something similar. I thought it was the temperature throttling but GPU temps were in check which suggested something else perhaps getting too hot and throttling.

I get around 2150 in Heaven at best.
 
I'm not sure what it is tbh, at stock oc using the heaven thread settings I got 2247 @ 1080p, that was +65 +590

Yet whack the smidge of extra volts in, +116, +595 I got 2232 o_0?
 
I've found in heaven score starts to degrade if i get very close to crash speed. One of my cards will finish the benchmark at 1370 but the score is, like yours, lower than at 1350. It flat out crashes at 1380+
 
So, like the giggling schoolgirl I am, I got a second one.

The second card isn't a very good clocker, which sucks. You'd think they bin them better. Although with two they don't need to be tbh. The memory can only go to +430 before severely artifacting (disco), and the core +45 (stock volts). The ASIC on the first card is 99.6% and the second 97%.
It matches the first card on the out of the box speed but the first overclocks further.

The new card runs cooler though at the same clocks. I guess the TIM was applied better. Atm the new card (bottom) is idling at 23c and the top 29c (the top card never went below 29c when it was on it's own). Temps are pretty low because my pc is right near the draft from the window. The mesh on the front of the 600t is cold to the touch :D.

Max bf3 temp earlier in the day was 65c on the top card which is coming close to throttle, and it wasn't a very hot day. But tbf I am running a window panel. SLI here is still cooler and quieter than a single 580 phantom lol.

Now fingers crossed for fullcover blocks, preferably not EK >.<.

I see ocuk were selling these for £449.99 over the weekend but have dropped them to £437.99 to match/beat competitors. That's cheaper than the standard twin frozr 680 o_0!

Some food for thought.
My 7970 lightning has ASIC of 67.5%, max oc of 1207(not great for these, average about 1300 from what i have read) needs 1280mv for this.
Idle temps 32c, bf3 load 61
Heaven 1080 AA x 4, tess normal 2238,

So pretty similar.

Hoping for better under water.
