It could also possibly be cause by not having dedicated PCI-e cabled from your PSU to the GPU (2 of them).



It also looks like you don't have your voltage slider maxxed. You are only getting 1.268v instead of 1.281v.

I also think the voltage table needs editing. The voltages are too far apart in the upper CLKs.

Hope this helps smile.gif

Thanks for the info.

red area is loading screen form 3dMark when clocks was drooped - so it is OK.

PSU- Platinum 750W PSU -Leadex has 1 line of 12V - 62.4-748W for all 12V parts in computer.
I think if would be a problem with the power supply, there should not be the effect when you add a 2W in the line PCI-E (from 75 to 77W), because we have one line for all 12V. But after adding 2W everything is working properly.

Cable - connected by original Leadex PSU-GPU cable. First cable for 6pin and second (separate) cable for 8pin. I try to connect GPU by one cable splitted to 6 and 8 pin effect the same.

About Voltage - I specially limited voltage to 1,26V to not have higher temps.
I add voltage to 1,281V for test but there where no effects.

About Voltage and clocks.
My idea was to keep fully worked Turbo mode.
I thought that I should keep same voltage for same frequency.

Example:
before OC in orginal bios for 1202Mhz we have CLK 54 - 1,000mV-1162,5mV
after OC (to 1582) 1202Mhz is in CLK 44 so I set 1,000mV-1162,5mV for state CLK44
is this wrong??

regarding OC, when I overclocked by Afterburner there is no problem with Power - only Vrel - limited Voltage.

Actually I condensed your log and removed all idle/loading screen data first. Note the time stamps. smile.gif

You can use the Gigabyte MUMOD 970 BIOS in the OP for a guide as the values will work for your GPU also. It would be much easier for you to open up the BIOS and see yourself.

I am not as familiar with EVGA cards but DarkAngel74 I am sure could give you some good advice on his thread. http://www.overclock.net/t/1573148/evga-gtx-970-ssc-gaming-acx-2-0-2-0-ftw-2-0-custom-uefi-firmware

I recommend just going for the AX 1500i, it is peace of mind and one of the highest quality power supplies on the planet. It has a Platinum 80 plus rating also.
With a MOD BIOS where wattage is increased, there needs to be a "SAFE" method of delivering that power. We don't want wires heating up and melting right? Cable management is not a priority here, safety is smile.gif. Any time a GPU PCI-e is shared, split, doubled up however you want to phrase it (ANYTHING other than (2) seperate and dedicated PCI-e cables from your PSU direct to the GPU) you will be attempting to draw too much power over a single PCI-e rail.

You know what ? When i decided for making a 980 Ti SLI Build with those G1 Gamings i never thought about my RM1000 beeing to weak , not even a second . Never thought i would need to buy anything more then my RM1000 on some day so i dident included the PSU in my thoughts whatsoever . Then when i had my card under water last week and was pushing her hard with 1.274 ( shown volts ) and was reading out the Power draw i began to realize that my RM1000 wont be enough for handeling two of those in SLI with your H2O bios and its max voltage . At least it wouldent be enough to feel comfortable about it and from what your posted even not enough at all . I mean there are some other power consuming parts on my build aswell . Not just these two 980 Ti´s with the H2O bios , also an 6700k 4.8 Ghz @ 1.312v , two SSD´s , 8x180mm fans , 5x140mm fans , 6x120mm fans , two EK DDC Pumps and some other stuff i propably forgotten . So when i started considering all this i began to realize that the RM1000 wont do the job and i was like damn , i realy need a new psu ( i couldent realy believe it ) . Anyway long story short , no compromises will be made , ordered an AX1500i instantly . Looking forward to that specialy because i can run dedicated 8Pin PCI-E Connectors for each Connector on the GPU ( the AX1500i comes with four of them , perfect , all i need for my SLI Setup ) . That feels better then having to use those Splitter cables as it is now with the RM1000 . I also have a feeling that the AX1500i could be my last PSU i have to buy ever tongue.gif , but dident i said this about the RM1000 aswell .... lets see what the future brings biggrin.gif .

Awesome! You won't regret it, it is an awesome PSU. I said that about my old 1K also tongue.gif. Just a heads up, the PSU can be monitored but it takes up an entire USB header and the software is only slightly better than OC GURU II (yes, I took a cheap shot at Gigabyte's OC app! LMAO!). It is absolutely a complete WASTE of a USB header and could potentially use CPU resources so you may just want to plug in the cable when/if you want to use it rather than permanently install it (you'll never use it after you use it once lol).

Also, you can upgrade the cables to braided if you want to go all out. The default cables are high quality but VERY stiff. The braided ones are REALLY nice. Lots of colors, lengths but yes almost another $100 by the time you add the 24-pin MB cable that isn't included (lol).

I moved this post because I modified the BIOS (sorry about that). I ended up checking out Dante's tweaks and think through his help we've isolated the Super Throttle Bug! I was able to get a couple of successful runs in 4K without seeing the issue!

As you know I've been keeping the 980Ti BIOS' in "BETA" until the STB issue was resolved, which I thought would require a new BIOS from Gigabyte but in fact a solution was found. Thanks Dante for this tip. We know it had to do with voltage and there was CLUE here the whole time that now makes sense.. We noticed that with GM200 the voltage defined in the BIOS is actually one step lower than what you would actually see under load. For example, V5BETA is configured for 1.262v in the BIOS but actual voltage under load will be 1.268v (the next voltage tick). We thought it was strange but didn't think too much more about it. Well finally the adjustment to the upper voltage sliders that corrects the STB is also ONE VOLTAGE TICK off so there is the correlation of the voltages.

This means folks that this BIOS is possibly a MUMOD candidate if all tests well thumb.gif


UPDATE:

V5BETA AIR BIOS for Gigabyte GTX 980Ti G1

V5BETA_DP_AIR_1.268v.zip 152k .zip file

         This is the F4, DP BIOS


What's new in this version?

✿► V5BETA is identical to V4BETAF4 with the exception of the 2nd voltage slider, upper VOLTAGE TABLE and MAXIMUM VOLTAGE allowed.

✿► Maximum voltage has been increased to 1.268v (1.262v in BIOS). V4BETAF4 is 1.237v

✿► Super Throttle Bug squashed


GOALS OF THIS TEST

Since many of you are looking for more overclocking headroom (some of you even trying the H2O BIOS on AIR, NOT recommended) I wanted to provide a version of this BIOS that may allow some additional overclock headroom but still be a viable AIR BIOS (knowing that GM200 is a BIG and HOT GPU).

The voltage for the AIR BIOS V4BETAF4 is 1.237v. The voltage for the H2O BIOS is 1.281v. This new V5BETA lands right in the middle with 1.268v.


TESTING GOALS:
(1) To verify if the additional voltage provides any additional overclocking headroom
(2) To monitor and compare temperatures from V4BETAF4 to V5BETA

As always, BOTH Power% and Voltage sliders in your fav overclocking app MUST be maxxed out for overclocking.


a custom fan curve is mandatory, STOCK isn't good enough for a MOD BIOS



Q.> WHO can flash this BIOS directly?
A.> This is an F4 BIOS. It is compatible with Gigabyte GTX 980Ti G1's with an F3 or F4 BIOS. It is also the DP BIOS (vs the DD BIOS). You MUST have the DP BIOS active to flash this directly.

Q.> HOW can I test if my 980Ti G1 is an F10 card and/or I have the DD BIOS active?
A.> Just extract YOUR BIOS and open 2 copies of maxwell BIOS tweaker side by side one with this BIOS and the other with yours. Copy ALL settings from ALL TABS identically. Triple check! Use TAB and ARROW KEYS to adjust the values more easily.

Any questions just ask! smile.gif

When iam interessted in a new component i do quite an exesive research first before buying it so yeah i know about corsairs link stuff . Dident planed to use it tho , iam realy not interessted in monitoring a psu lol . Maybe will do it for a day or two just to see what the system is pulling ( if thats possible ) but i wont have it on the usb header consistantly , as i said not much interesst in monitoring a psu lol . Also i know about the corsair cables wich are in the box of the AX1500i , basically the same stiffs like the RM1000 has . I realy hate them . Aesthetic wise they dont look realy that great but the stiffness of them is a pain in the back . I also know about the Corsair braided ones but i dont like these either because of their long heatshrinks at the end but i got something in the back wink.gif . I will go for these : https://www.caseking.de/cablemod-c-series-axi-hxi-tx-cx-cs-m-und-rm-cable-kit-schwarz-gruen-zuad-496.html

Awesome never new others made cables for these Corsair modular PSUs, cool smile.gif

Hi Guys!

So I get on my Gigagbyte G1 stable:
Core: +120mhz
VRAM: +550mhz
Power: Limit 110%
VCore: default/ no change (Raising the voltage doesn't get me a higher OC)
Temps are around 60°C.

I guess this is quite all right. My question is, would I really gain anything from flashing a custom bios? I suppose at most I could gain +30mhz on core, right?

I dont think its really wotht he hassle but looking forward to your feedback.

also below the gpu-z log from my fire strike run-

GPU Core Clock [MHz] , GPU Memory Clock [MHz] , GPU Temperature [°C] , Fan Speed (%) [%] , Fan Speed (RPM) [RPM] , Memory Used [MB] , GPU Load [%] , Memory Controller Load [%] , Video Engine
1529.8 , 2029.5 , 61.0 , 72 , 2294 , 1814 , 0 , 0 , 0 , 0 , 82.0 , 4 , 1.2180 ,


Thx and cheers

Hi there!

Yes you sure would get benefits with a MOD BIOS. You are never guaranteed any additional overclocking headroom but that's possible. If you don't you would still increase power limits, remove perfcaps, virtually eliminate throttling etc. smile.gif

Check out the release notes in the OP and especially the Mini-Knowledge Base about DD vs DP BIOS so you are clear. Any questions just let us know smile.gif
