@ OccamRazor


I need help with a problem I am having with two new 780 classified with helix mem.

Before I reflash my bios I did a baseline benchmark with Heaven and Valley then, nothing crashed and the score was pretty good, I was like great better than my old once.

This is were everything went to Sh..t. I flash the bios with version 3 from the Classified front page, everything took, so great. I started overclocking with PT at 200 %. First I did offset up to a +200 before it crash, couldn't go over that even with the voltage set to 1.35. I went to MEM got that to +350 before crash. Now I tie the two together and everything crashes.

I dial everything back to zero with voltage to 1.25 and Pwr target to 200% still crashes, everything back to zero and no good, still crashes.

I am on a new windows 8.1 install, I did this for the new cards because of the problems I was having with the old ones.

My two cards are cooled by, two H55 and fans for the Mem, still using the front plate to aid with cooling and a fan on the back plate to aid with the cooling.

My temps at idle is 38degs for the first card and 35 for the sec card, at load my temp are 58/48 the highest it ever gets.

I notice the bios version for the new cards are different from the old cards. 80.80.31.01.80 and if I remember the old ones were 80.80.21.01.

I flash the cards back and everything is good.

Please I need some inputs or idea. I am about to go full water. I don't think it's the cards, I think it's something to do with the Bios.


Thanks

Probably memory timings, send me your stock original bios please and ill see whats going on! thumb.gif

Its just a limit... its the max quantity if current you are allowing the card to draw, not the quantity if current it draws instantly!

Your card has 6 phases (for the core) x 60A each = 360A (DC current amperage to watts conversion)

P(W) = I(A) × V(V) » P(W) <=>

<=>360 x 1.2V = 432W (Maximum theoretical draw for the core)
<=>360 x 1.3V = 468W
<=>360 x 1.4V = 504W

Plus 2 phases for the memory and to power the rest of the card, so you are safe unless you dont cool your card properly! tongue.gif

Got it:) seems I've reached my stable limit! Now last question... when player swtor the game stutters like CRAZY... jumping etc.. any reason why this is? I've tried messing around with v sync etc but no difference.. obviously the card is powerful enough to run it?

You are going to have your hands full in no time! lol
Now the hard part begins! Software problems! just switched from tri-monitor portrait to landcape and most of my games refused to start, some recognized the new res but most didnt, even some do not support 5760 x 1080 but supported the 3240 x 1920, funny right?
Good luck! tongue.gif

Haha damn, seems to me like swtor is poorly optimised for nvidia cards, I'll try some of those methods to fix the issue.. life is never easy for an overclockers. . tongue.gif..

Thanks for the reply.

I did I stress test on my mem, but it seems ok. will put it back to stock and see.
How do I send my VC bios to you.

cheers:thumb:

srry wrong mem, thought you meant cpu mem.

try forcing triple buffering with d3doverride STAND ALONE. download it, install it, go down to the right hand side of the start bar, open it, enable TRIPLE BUFFERING (with game closed). Note: Make sure you only have V-sync on in one place. "use application setting" is normally your best bet, with it on in game.


The triple buffering in the NVCP is for OpenGL only, because Nvidia is lazy.

How can I send the bios to you? And here is my last trouble shouting.

ok, I tried one card at a time in different PCI slots, #1 and #2 bios and I am getting the same results. they both crash with default settings. But i can put in a +650 of mem before if crushes. If i dial that down and add core at all they crash.

I know it's not a power supply issue, in using a power meter, the draw is only 550 watt with one card. Could it be a MB. The cards are only 5 days old.

thanks

Hmmm.... 1.3v = 468w theoretical on the core huh. 39amps?

Ive only been toying around with my new classified but i have a decent but not enough power supply to overclock yet with two 12v rails 25amp each. I underclocked to reference speeds as a precaution so i dont hit my supplys ocp.

I saw this nice $80 deal for beautifully nice seasonic 80 plus platinum 660w supply come on today and its advertised to have a single 55amp 12v rail.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151121

Got me thinking with that much rated it may only be 660w but could possibly do the job. My 2500k@4.6ghz definitely needs to factor in but once i have the go ahead id like to push my classy to 1.3v and as much core speed as i can get. Im sure i will hit it with 1.35v for fun to get high scores in 3dmark Unigine etc.... but back down to 1.3v for 24/7 use.

Could this work? Theoretically how many watts/amp does a 2500k pull? I dont ever plan on going sli.... but i mean... isn't seasonic platinum stuff the shizznit? The two reviews i see for it show near perfect ratings and fully within advertised platinum rating.
