It is said to be the fastest card that rivals the HOF or Classified but the 2 I got can't even make it past 1100MHz OC with no Mem overclocking. One of them barely made to +100MHz OC while all the reviews are getting at least 150MHz or higher OC on stock cooler. I tried almost everything, offset power limit, adjusting voltage to different values. No help.

Running on stock won't crash in 3Dmark or Crysis 3, but that only has a max boost clock of 1100MHz, really no point getting the lightning if I'm just running on stock.

The ASIC quality from GPU-Z reports 63.1% and 65% I don't know if that's of any relevance.

I used to have the EVGA GTX 780 Classified and without voltage mod and regular BIOS I can get +105MHz and +400MHZ mem OC easily with MSI afterburner and a max boost clock just short of 1300MHz. Actual in game clock is around 1240MHz. The ASIC quality was 78.4%. Hoping to get higher OC with the lightning so I exchanged but the result is VERY! disappointing.

Any suggestions?

I will keep on updating here and my original thread:
http://www.overclock.net/t/1460251/msi-gtx-780-lightning-is-horrible-or-just-a-bad-batch

Sorry to hear of the trouble. 1) Use Nvidia Inspector and hover your mouse cursor over the memory type. It should identify it as hynix, samsung, or elpida. Unfortunately, a large number of Lightnings come with Elpida memory which tends to be quite inferior in terms of overclocking. Mine has Hynix and overclocks better than most if not all elpida chips. If you have elpida, then you are probably looking at maybe in the neighborhood of +200 on the memory. 2) Be sure that you are using the latest MSI Afterburner software beta 18. Go to settings> General> Compatability Properties should be about midway down> check unlock voltage control and monitoring> in the drop down box beside voltage control choose extended MSI (this will give you a higher voltage limit). 3) Max out the power limit and start tweaking. Please be sure to apply the settings that you with the button at the bottom. 4) If you want to go further, then you can use rbby tool and a custom bios that you can find on the 1st page of this thread. The custom bios will allow you to increase the power limit to 287-300%. The flashed bios in combination with rbby tool will allow you to increase the voltage quite a bit. If you are using the stock cooler, then I wouldn't suggest going too crazy with the voltage. Each +100 on the voltage increases the core voltage by 0.1 volts. +200 would be 1.3 volts or so. Personally, I would not be comfortable going over that on air cooling. The biggest factor will come down to temperatures. This will probably be more of an issue when they are in sli at least on air cooling.


Every card is going to be different for better or worse. There is definitely a silicone lottery with whatever card or brand that you choose. For instance, my Lightning (ASIC 74%) has the Rev 4 bios flashed onto it because mine has Hynix memory. I am still in the midst of tweaking; but it looks like my 24/7 card settings will be the flashed bios with the power limit at 287, core voltage at +100, core at 1400, memory at +800. My waterblock allows me to get a better overclock than when I was using the stock cooler to make sure that the card was working well. Watercooling appears to be where these cards really shine because it really keeps the temperatures in check.


Do you have an adequate power supply? One of our members was pulling about 800-900 watts out of the wall with just one highly overclocked card, and you have them in sli. Most people are recommending 1200 watt or greater psu if you plan to overclock sli lightnings along with overclocking the rest of your system. Anyways, hope that you get everything sorted. Good luck. thumb.gif

Well, I've got another Lightning on the way, but I think I've maxed out the current card I have. I've got it running stable 24/7 at 1240 core/+325 memory. Core voltage is at +38mv and memory voltage is at 1630mv. I can get it semi-stable at 1280 core, but that seems to be my limit at the moment, all on stock bios by the way.

I've also decided to jump headfirst into watercooling as well...and I certainly hope it turns out to be worth it! I just dropped $650+ on a complete water cooling setup, but here's what I got...

2x EK-FC780 GTX Lightning - Acetal+Nickel
- Optional SLI Fitting Add CrossSLI Danger Den Fittings Set
- Fitting Size 1/2" Barb for 1/2" ID tube

A handful of XSPC G1/4" to 7/16" ID, 5/8" OD Compression Fittings in Black Chrome Finish


XSPC Raystorm Extreme Universal CPU Watercooling Kit w/ AX360 Radiator/D5 Pump/Res
- CPU Waterblock XSPC Raystorm - Intel
- Block LED Color Blue
- Fitting Size 7/16" x 5/8"
- Compression Fitting Color Black Chrome Finish
- XSPC 120mm Radiator Fans XSPC 120mm 1650RPM Fan
- Tubing 2M (6.5')' XSPC HighFlex Water Tubing - UV Blue
- Coolant No Coolant


Phobya G-Changer 280mm/60mm radiator





I'm still running my 950w power supply, but do you guys think all this should be sufficient to max out two cards and keep a 4770k humming happily at 4.7ghz and up? I'm still shocked I just spent that much on water cooling parts, so please reassure me I did well lol...!!!

Congratulations on your jump into the world of watercooling. I know that my first watercooling build was quite eye opening in terms of of the cost.thumb.gif Everything that you get should be able to grow with you if you if you decide to expand so the initial investment to me is well worth it. I believe that you will enjoy it. One of the best things about it is that you can make it into exactly what you want. If you find out that you need more radiator space, then you can just add another or get a larger one etc. I honestly can't speak to XSPC personally as I have gone with Swiftech and Alphacool components. The EK lightning block is VERY nice too. It has terrific cooling on the vrms especially.

The Alphacool rads are what keep things nice and chill for me. I went overboard on my last build due to wanting something that would last a LONG time. My single Lightning right now is on a 480 mm + 280 mm worth of rad space alone. I had to fill my Corsair 900D up with something.biggrinsmiley.gif

One of the most important things to remember though. Don't put any aluminum into your loop. Just don't do it. Personally, I go with just plain ole distilled water with some PT nuke to keep things nice and clean. If I want color down the road, I will just buy colored tubing rather than having dyes clogging up my loop. This is my personal opinion though. Be sure to read up on watercooling and learn as much as you can. Best of luck to you. Let us know how it goes.thumb.gif

This is wierd, when i set it into LN2 bios, the LED's is all on at all time. only the stock bios turns some of them off.??

That is normal I believe. That is how mine does too. Running the flashed bios now, mine stay on 24/7. I believe that is how the ln2 bios defaults. The 1st bank would only come on when a game or benchmark was booted up under the stock boost bios.

Yeahh that's my thoughts too, everything seems to work just fine.

Now i have another question, this "throtteling" does that mean the powerlimit is reached or? and is this the only time you should touch the %-limit, og should the %-limit just allways be set to 300 or?

You welcome. If you or anyone have any question just post it here using the @ icon above it will direct the msg to me like a pm.

Guys i have another question too, is there a way to prevent the Lockdown? or whatever it's called, when you got unstabel Clock, like my 780 goes from 1100MHz to 575MHz when i try to push it too far, what is the reason for this, and is there a way to prevent it?

Also i have another question too, from post #2627:

When overclocking & getting instablility, more voltage is needed to stabilize & keep going. More voltage means more heat, so need to keep an eye on temps.

The cards can throttle from power limit or temps, stock power limit is usually reached before a temp limit. Skyn3t has modded bios' in the OP with higher power limits to keep the clocks going higher, if reaching the power limit flashing one of his bios' can keep that under control.

Thank you, i have flashed one of his Bios, the REV4 for my Hynix memories. atm the heat should be no problem as im not going very high yet, soone going to get water for holding down the temps.
Okay, so the throttle should stop when i set it to lets say 130-140% power limit?. if im not going very high yet.

Can you tell me why the card can "lock down" and only perform 575 MHz after i have had a crash or so?
