Gotta love the B1 revision... are people buying those now getting B1s, or did they produce so many A1s that they will not upgrade the cards? Or is it just the lottery...
Pretty much all cards have been B1 for about 6 months here in Finland. B1 doesn't automatically mean good overclocker.
As far as i know all Palit Superjetstreams that get sold right now are B1s. At least at the online shop i bought it. I would look at how much cards got sold in the individual shop you are buying. If they dont sell alot of cards, chance are big they still have some A1's in stock.
True but you do see more B1's gong over 1200mhz before A1's. Both of mine are A1's, and 1201 is the tops for them. At least without a Volt Mod.
It's still luck of the draw. You could get a higher oc rev a than b. My cards are rev b and 1150 max stock volts and only 1189 1.2v. Though 780ti are harder to oc than a 780 because of the full 2880 cuda cores I'm guessing.
Was thinking about picking up a 2nd 780 on the cheap, I've no experience with multi GPU's though. Scan are selling Zotac 780's for £224 atm, ugly cooler but a nice price for new with 5 year warranty. It says overclocked, I assume the card will just downclock to match my EVGA card when placed in SLI together?
decided to buy my self a christmas gift. ordered a slightly used evga 780 classi card. so now going to have 2 of these cards for sli. edit.. just realized I might not be able to have my PCI tuner card in. because its right next to the slot for the second gpu.
Right, so I was playing with my bios again few days ago, but it caps @ 1.187v no matter what,.. I raised main voltage to 1.237v but it doesn't want to overvolt higher and looks like 1228mhz+ needs 1.20 - 1.225v.. that's why I always TDR in very demanding games if I go past 1228mhz. When I looked @ this thread someone said, I maxed the voltage slider and now i dont have use that MSI AB hack anymore.. Should I max to 1.31v too? http://www.overclock.net/t/1452223/...7-added-tdp-unlock-gtx-780ti-780-titan-gtx770 Is this a MSI AB issue or driver limit? I tested evga precision and it seems to unlock it with "voltage boost" but no luck, it still TDR in most demanding benchmarks/games..:infinity: I did try that MSI AB softmod once, but that LLC hack is abit weird, so I reverted to default..
You're running into the card's built in vdroop (a fun feature). There's a hack that Zawarudo made before he passed away that enabled up to 1.3V, but it only works on reference cards with the Nvidia voltage controller. However, going that high on air is an extremely bad idea and will almost always result in a dead card. These don't have VRM temperature sensors and they're already getting pushed quite hard with the clocks you've got there. I'd just leave it alone.
Yes I tried that mod once, but I think I didn't use LLC back then and voltage was all over the place.. I wouldn't enable whole 1.31v, 1.213v would be enough, meh.. stupid limitations. I think my is reference too, just with custom AMP cooler on it.:nerd:
It might not be. Check google to see if you have the NVCP voltage controller. On mine I could push 1.212 all day, but it didn't help at all. I still ran into a wall at 1189. Never tried the LLC hack because of that.
I see, well so far I could run @ 1240mhz in Monster Hunter Online benchmark, while by older Monster Hunter Frontier it TDR anything higher then 1215mhz which is also my hard limit to pass all.. Guess this is my wall too, its still ok I think. Btw is yours A1 or B1?
Mine is an A1, unfortunately. Although I guess it's decent given that the ASIC is like 65% or something bad like that.
I see.. Speaking of gpu boost Can I limit it to boost less? I tested 1006mhz > 1058mhz, but biach boots 143mhz no matter what, this makes it stock 1150mhz and that is on its limit @ stock 1.162v, not 1000% stable, if I raise main voltage to 1.178v it doesn't stop at 1150, but boosts to 1163mhz then.. 1137mhz is ok, but for that I need base 993mhz > 1045mhz. So I was thinking to lower boost for 13mhz, base 1006mhz > boost 1045mhz, but when I do that it still boots for 143mhz. Is this value 1150 something? I see its the same by stock bios 941mhz or if I raise base clock for 60mhz making it 1006mhz.. I would put 1137 there where it says 1150 EDIT: ok this window is not it either.. Saw this here, http://overcloqc.com/threads/2921-E...-BOOST-2-0-vBios-Unlocking-Overclocking-Guide
NOTICE: Bios modified is official?? If not then it may void warranty. But... You don't need BIOS modified. We increase power limit from 100% to 105~110%. I have increased to 106%.
What does that have to do with anything? Notice: I backup'd original bios and yes this is my own mod from original bios edit: Anyway I also asked @ overclock.net in KBT1.27 thread, just in case.
