post #1931 of 7827
dph314, The issue I have doesn't have to be related to every Ln2 bios. It's just that mine has a memory leak and cant play games that hit the 2gig memory mark because the buffer doesn't flush and go back to 1900 which is the normal limit for cysis 2 on ultra. When I played BF3 maxed out on the ln2 it worked like a charm since that game never exceeded 1.5 gig memory usage at any time.

Can anyone tell me what the PLL voltage does ? I know via Afterburner you could change voltage,mem voltage, and pll.

PLL voltage if increased can make the Lightning stable on a certain overclock ? And what about mem voltage ?

You wont know for sure until you test in game play and see if the memory flushes correctly after 2000 or if it just hangs there and causes a crash.
The stock bios on my card is very good so that's what I'm using now.

I assume BF3 won't fill the memory at 1080p?

What game/benchmark can I use that will fill the memory at 1080p?

mem voltage help stabilize your memory OC

PLL is "phase locked loop." PLL voltage helps any device that is clocked against a reference clock, where the resulting clock speed is higher than the reference clock speed. As far as we need to be concerned, it can help stabilize the overall OC of your card.

Well I can tell you for sure that Crysis 2 with Maldo mod will. Not sure if I have any others that do. But yeah the Maldo mod is a easy install if you're new to mods, so it shouldn't be a problem. I would give that a go.

I don't remember checking usage for the New Dawn Nvidia demo, maybe try that too?

Not sure if this has been mentioned here already, but just wondering if anyone has tried flashing the Lightning BIOS that goes to 1.2v to a reference card. If so, were you able to up the voltage? Just asking because of all the talk about the modded Gigabyte 680 BIOS that people are flashing to their cards and saying they were able to up the voltage and therefore get better performance.

Beings I have a MSI 680 Twin Frozr, I would probably rather try flashing the Lightning BIOS to my card than using a modded Gigabyte BIOS if it would work.

No, the only cards which can flash to the MSI lightning bios are those with the same CHIL chip. As for the modded GTX 680 bios it allows 1.21vc on reference GTX 680's and you dont have to make any adjustments with MSI afterburner as the bios flash simply removes the 1.175 limitation and moves it up to 1.21.

All reference cards go up to 1.21V anyway, its just not reported by software. Its been discussed and verified via voltmeter before on reference cards, there were some posters at hardocp discussing that months ago. Chimax83 I think it was, he found reference cards going up to 1.21V (but reported 1175mV in software). That is weird though, that better results are coming from a modded BIOS....hmm, wonder if something else in the BIOS is helping (power %? Overcurrent protection? Shrug) Cool for them though for sure whatever it is.

To answer the question, no the lightning BIOS would not work for you. Whatever modded BIOS this is , you may want to give it a shot.
post #1940 of 7827
Im not buying it, to many folks such as myself who previously reported seeing only 1175 via GPUZ before the flash now see 1.21 after the flash in GPUZ "yeah I realize you will say its a software error" and also have an extra 50mhz on the core to back it up. There is nothing magical about the bios that would give another 50mhz to the core besides the obvious fact that the cards are now getting more voltage.

It could possibly be that a few 680's were already peaking out at 1.21 while most others such as myself were stuck with 1175vc.
