Doesn't look pretty? it's damn good already, I've seen way much worse in terms of cable management and color pairing !

Hey thanks Kimir! Yeah im proud it lol, the case made it pretty easy to tuck wires away. I really like your setup, the white sleeves look deadly! Eventually (when i learn to OC) I'd like to be set up like yours actually... although I'd probably need a new case lol.. Duel cards, Liquid Cooled with the rad on the front, yeah that's my goal!! biggrin.gif

Can you guys do some benchmarking with 1 lightning with the new unigine 4.0 at 1360mhz clock and 7100 memory cause i want to see if my card is running up to par/normally thanks.

I think my card is deteriorating, now it crashes at stock clocks/volts in new Heaven 4.0.

Too bad I can't RMA it since I bought it in the states and I live in Argentina frown.gif

For a while, I have been having problems with afterburner 2.2.3. The voltage doesn't seem to save, so every time I boot up, instead of the +93mv, I'll have a different number.. just seems random. Anyone know if the hack in 2.2.4 or 2.2.5 work to remedy this? Can anyone point me on how to do it and if there are any advantages?

Another quick question.. on my lightnings, the core clock constantly fluctuates when playing games. It never stays pegged at 1375mhz that I set it to.. instead the clocks on both cards go up and down during any game.. down to about 800kHz sometimes which causes alot of stuttering. Multiple drivers haven't changed anything.. running with a 2500k on a Maximus Formula. Going to do a reinstall tonight to see if it helps.

Should I have the two sli connections connected on the cards via two bridges?

Awesome, will try that when my system is up and running. +REP happysmiley.gif

First question- Yes, I've heard the versions after 2.2.3 do fix this bug, which is the reason many have decided to cease using 2.2.3. All you need to do is the config edit to allow for voltage control, and the hack works the same way as far as I know, just with different addresses for the values.

Even on the LN2 BIOS, clocks will fluctuate. If you set 'Prefer Maximum Performance' in the NVCP, then the clock won't drop below the base clock speed of 1202mhz. But with an overclock, the offset is added kind of like a boost speed. So it can still drop from the boost speed to the base clock when the load drops, no way around that. It's not a problem though, the speed is there when you need it, so it doesn't negatively affect performance. And during a bench you'll have your full boost speed, so, yeah I don't mind it at all.

Thanks for the response on this! Would you happen to know where I could find out how to do that hack on some of the later versions of AB? It gets old having to remember to up the voltages every time I turn the comp on, not to mention that when I forget to, I'll start a game only to have it crash 15 min later because of the lowered volts.

I have NVCP set to PREFER MAXIMUM PERFORMANCE on my end - and I do understand that the core clock would normally fluctuate slightly. I mean, when I do a Heaven Benchmark or 3dMark, the core and memory clocks stay pegged at 1375mhz. However, whenever I play a game, while I do expect them to move around a little bit, I am getting crazy things like one card dropping down to 800mhz for a few sec and then shooting back up.. then the other card will do it.. and the one will drop to 1100 ish.. And i believe this is why I am getting sooooo much stuttering during gameplay. Its different than microstutter, its almost like breaks in the screen, its very annoying. I'll be doing a full wipe and trying out W8 tonight (just cause I want to try it) and see if it persists. Hopefully not.

Hey, have you read of 680 Lightning-L?
http://www.xxxx3d.com/news_story/msi_geforce_gtx_680_lightning_l_graphics_card.html
( I swapped a word in address with xxxx as I don't know if it's legit to post a link to another forum...)

There is a topic about it here as well.

On a side note, I have a question for experienced watercooled lightning owners.
I plan to get the CPU into the custom loop I started with the 2 lightning and I have couple of option for the flow direction, I'm not sure which one would be the best.
The first option would be:
pump/res -> CPU -> 240rad -> GPUs -> 280rad -> back to pump/res
Second option, the invert :
pump/res -> 280rad -> GPUs -> 240rad -> CPU -> pump/res
Others option like :
pump/res -> 240rad -> CPU -> GPUs -> 280rad -> pump/res

The 240mm rad, replacing the H100i position on top, will have my actual Corsair SP120 fans and the 280mm I already have, located in front with the two 140mm fractal fans as intake.
Suggestions?
