MSI GeForce GTX 680 Lightning

OWNERS' THREAD

379
  • I know we have at least two different threads going with discussion on our new Lightnings! I thought this card has gained enough popularity and performs more than well enough to deserve its own dedicated thread!
  • Validation of ownership: 1.)a picture of your card with a name tag in the pic or 2.)a screenshot of your invoice with your OCN name somewhere (blackout personal infos)
  • There will be two columns on the spreadsheet dedicated to OC. One will be for max OC Heaven run, the other will be max OC for 3DM11 run.
  • I know many of you have already posted your OCs and pictures of you cards etc. in the other threads, but since this is a new thread we will be starting from scratch! Thus, you will need to resubmit screenies of your max OCs for both benchmarks as well as pictures for validation of ownership.
  • Lastly, let's keep the conversation and competition clean ... Avoid debates between 7970 vs. 680 if possible.

    ... Have fun!

Proper Post/Submission Format




  • Please make all submissions in a post, then PM me with a link to your post!!.
  • Submission posts should begin with your submission information (as outlined below), and end with an image of your validation screenshot!

If you are already on the sheet, please use this format:

UPDATE

Username: **********************
Max Core OC: ************************
Max Memory OC: ************************

**Insert validation screenshot (according to instructions below) here**

(Report Max OC in terms of MHz, not your AB offset setting)

If you need to be added for the first time, use this format: (same as above, but title it with "NEW", instead of "UPDATE")

NEW

Username: **********************
Max Core OC: ************************
Max Memory OC: ************************

**Insert validation screenshot (according to instructions below) here**

(Report Max OC in terms of MHz, not your AB offset setting)

As my busy life prevents me from skimming through the pages of the thread to check for new submissions, please remember to PM me with a direct link to your submission post. (to copy the link of your post, right-click the " post # " in the top right of your post [i.e.- where it says "post # xxxx of xxxx"], then choose 'copy link location')

Max OC Validation:
  • Open Afterburner graphing/monitoring tool before running benchmark, that way when it is finished, you can take a screenshot that shows your max core and max (effective) memory frequencies.
  • Make sure screenshot shows the core and mem frequencies!! otherwise, what good it is it??
  • Max CORE and Max MEM frequencies MUST be tested at the SAME TIME.
    This is how you will run the card most of the time (with both maxed out at the same time), so this is how we will report our max frequencies
  • 3DMark 11: **PERFORMANCE SETTINGS** Once the run is complete, take a screenie of your score AND the afterburner graph with your max frequencies highlighted (hover cursor on graph where your freq is at its max)
  • Heaven Benchmark: **DEFAULT SETTINGS** Since heaven stays on full screen after a benchmark run, take a screenshot of the finished run. Then minimize/go to desktop and take screenie of afterburner graph with your max frequencies highlighted (hover cursor on graph where your freq is at its max).
    ***clearly this is less than ideal, but until we get a better method of validating a certain frequency and showing that a run has just been completed at that frequency, this is what we will do
NOTE: scores dont matter for this thread, just that your card is stable enough to complete a benchmark run

  • Standard BIOS = boost depends on your chip
    LN2 BIOS = boost is always 1202
  • Standard BIOS = obeys driver voltages, goes up to around 1.325V with 2.2.3
    LN2 BIOS = goes a bit higher, goes up to around 1.35 or 1.37V with 2.2.3
  • Standard BIOS= has kepler throttle and overcurrent throttle!
    LN2 BIOS= has *disabled* all throttle mechanisms and is ultimately more stable with maximum overclocks
**A NOTE ON BIOS**

All MSI GTX 680 Lightning graphics cards have two BIOSs. One BIOS is a normal, non-OC version. The other BIOS is an "unlocked" "LN2 mode" version meant for OC. In order to have voltage control on your 680 Lightning, you need to make sure you are using the unlocked BIOS. To toggle between these two BIOSs, simply move the switch on the side of the card. To make sure you are in "LN2 mode" and using the "unlocked" BIOS, you need to look at the version number of the BIOS. You can view this information two ways:
1.) Open GPU-Z and look where it says "BIOS Version"
2.) Click the "i" Info icon on the main AB screen and it'll tell you the BIOS version you have

FOR THE FIRST 5000 LIGHTNING 680s
80.04.09.00.F7 (non-LN2)
80.04.09.00.F8 (unlocked LN2)

AFTER THE FIRST 5000, WE'VE SEEN THESE LN2 BIOSs FROM THE FACTORY:
80.04.28.00.3A (unlocked LN2)
80.04.09.00.3A (unlocked LN2)
80.04.47.00.19 (locked LN2)
80.04.29.00.3A (locked LN2)
80.04.28.00.39 (non-LN2)
80.04.47.00.18 (non-LN2)

The first 5000 Lightning 680s that were made shipped with the two BIOSs that are mentioned above. However, apparently NVIDIA has now imposed a new limitation that prevents all other 680 Lightning cards from having voltage control, even with the new Afterburner 2.2.3. These newer 680 Lightnings still have two BIOSs (one regular, one LN2), but the LN2 BIOS is no longer "unlocked" to allow voltage control above 1.175. Thus, if your LN2 BIOS version is something other than 80.04.09.00.F8, you have one of the new restricted cards. If this is the case, you can flash your card's BIOS (while it is in LN2 mode) with the unlocked LN2 Mode BIOS file (BIOS version 80.04.09.00.F8). Download this BIOS file here.

To flash the BIOS, download the latest version of nvflash here.
  1. extract the nvflash files to C:\
  2. save the BIOS file to C:\
  3. open elevated cmd window (hit start button, type "cmd", right click cmd icon, run as administrator)
  4. change directory to C:\ (type " cd C:\ " )
  5. OPTIONAL: type " nvflash --protectoff " then hit enter (turns off any error msg that may result from software write protection)
  6. BACKUP ORIGINAL BIOS: Type " nvflash -b backup.rom " and a copy of your bios will be saved to the nvflash directory
  7. type " nvflash -4 -5 -6 680L_UnlockedBIOS.rom "
  8. wait for it to finish
  9. reboot
  10. OPTIONAL: reinstall drivers

Download the "OLD" Unlocked LN2 BIOS

A NOTE ON MEMORY HACK TO BYPASS VOLTAGE LIMITATION OF AFTERBURNER
In this thread is information on using various different memory editors to manually bypass the maximum voltage set forth by the Afterburner software. Everyone needs to be careful using this method to control their voltages. it is a memory hack... which is a hack! when bypassing the programming of a piece of software, always keep in mind the risk of your actions. We are overclock.net, so i can appreciate one's eagerness to try and use this method, but please dont forget that there is always the risk of damaging your system and the hardware that it's comprised of

Tweaking Afterburner 2.2.4

VDDC_Generic_Detection = 0
VDDC_CHL8318_Detection = 46h
VDDC_CHL8318_Type = 1

Those lines disable NVIDIA's capped voltage control module, enable voltage control via direct access to CHL8318 and select offset voltage control mode for it.

Note: each card profile must be edited for SLI configs.

If having trouble editing the file you may want to try this:

cut & paste "VEN_10DE&DEV_1180....cfg" on desktop
make the change and put it back in the original folder

Would love another Lightning for SLI, but system would be slightly;) crippled without the RevoDrive3 X2. A second lightning would be right on top of the Revo.

do you guys think we should report our max OCs stable in heaven/3dmark as raw frequency or offset?

i vote for frequency because offset is bit less definite.

That said, guys, when you report your frequency, we need a screen shot of your finished benchmark AND afterburner graph with your cursor hovering over the max boost freq.
