obviously if you increase the max boost table clock then you are increasing the clock speed that the card will try to run in *every* voltage bin, so of course it is going to under-volt. if you want to increase the boost table clocks then you will have to increase all the voltage bins to match.

fwiw i have a 980 g1 and it has the same behaviour at stock as you describe (it varies slightly depending on asic)...mine boosts to 1366 using 1.218, and then if i increase the voltage with AB it will go to 1380 at 1.243. But my card at least needs nowhere near 1.218 volts to run at 1366...from what i remember it will do it at 1.100 or so. I have no idea where it pulls these values from to be honest, it's probably based on the ASIC and the max voltage in that particular bin.

i'm curious to know the reference card (or EVGA SC) behaviour at stock? what voltage does it use at max boost?

re oc'ing with AB core offset and under-volting, i think it's at best a design limitation that it undervolts under low utilization. from an end-user point of view it's completely unintuitive...at least for me, the behaviour i would like is that when i set an overclock, everything stays exactly the same except that it increases the max clock speed that the card will run at the max voltage bin, ie it can dynamically scale the clock between it's default for that bin and whatever offset you specify while maintaining the same voltage.

instead what it actually does is it adds your core offset to the clock that it will run for all voltage bins, so essentially it tries to overclock every voltage bin instead of just the top one. this is where the 'low utilization' crashes come from, as you've seen. eg with made up numbers, at an offset of +150 the max bin will run at 1354+150=1504 at 1.25V which is ok, but the base bin will try to run at 1228+150=1378 at 1.01V which is not ok. nvidia's engineers and driver team will probably say that it's all working perfectly and this is how Boost 2.0 is designed. maybe it's a marvel from an engineering point of view, but imo from an end-user point of view it's completely unintuitive and a crap design.

I agree, crap design.

hey guys im having a power problem with my msi 970 g4. it wont go above about 115% in power even though i have the slider at 120 and all other things in the bios modder are at 120 ish. i have a problem with voltage too, it says its at 1.275 which i know its reading wrong and is actually at 1.312v but it will drop to 1.2600 ish and around there. i want to stabilize the voltage before i do anything above my current max oc of 1575 on core and 8000 on mem.

Here it is, I created it again just in case. It should be same as Zoson's AIR bios apart from temp target, 3D Base clock, memory clock and power table. I left temp target on default, memory at 3805MHz, 3D Base Clock same as TDP Base Clock and power table on default. Can you please check if it is otherwise identical? Thanks AIR.zip 137k .zip file

lol ouch how's your finger? Everytime I've accidentally gone close to my G1 fans it's drawn blood! Anyway, good excuse to go under water....

I know this is a bit offtopic so I am sorry in advance for this liitle question of mine.

I am planning to do my first water loop and need I need help with few things.

I want to WC my 980 and it will be my only item in the loop so far. These are components:

Case: Bitfenix Prodigy
Motherboard: ASUS Z97i Plus
CPU: Intel Core i7 4790k @ 4.7Ghz
CPU Cooler: Noctua NH-U12S
GPU: EVGA GeForce GTX980 SC /w blower
SSD: Samsung 840 Pro 512GB
PSU: Corsair AX860
RAM: Crucial BalistiX LP 8GB 1600 Mhz

and now these are the things I want to use:

Block:

http://www.ekwb.com/shop/blocks/vga-blocks/fc-geforce/geforce-gtx-9x0-series/ek-fc980-gtx-acetal.html

Res + Pump combo:

http://www.ekwb.com/shop/reservoirs-and-acc/res-pump-combo/ek-ddc/ek-sbay-ddc-3-2-pwm-incl-pump.html

Rad + Noctua NF-F12 PWM fan:

http://www.ekwb.com/shop/radiators-fans-accessories/radiators/ek-coolstream-pe-120-single.html

I would like to postion my rad in the lower 120mm slot in front of the case. Here is the picture of what I have in my mind:



Can you please tell me how to route tubing (I mean where intake and output) and also what other peripherals I will need to complete the loop - like which exact tubing, fittings, stuff. would you recommend.

Thank you very for the answers. (you can write me a PM so we dont spam this topic smile.gif )

I would like to credit Zoson for making the H20 bios and clearing things up. So far, I have copied almost all the settings on this bios except for bins 24-34 and the fan profiles. I'm currently testing the bios on my 980 Jetstream (not the super jet version). I would also like to mention juniordnz for making me understand how vital the voltages are on those tables and for the other one who advised to adjust the mouse settings! I can finally scroll through every voltage stepping on MBT.

Currently testing 1531mhz, seems fine for the moment. passing my benchmark suites and playing games like ACU.

Yeah, I'm pricing some full cover EK blocks for STRIX now... $125 a piece, ouch. would solve my 110c+ VRM temps though. not sure if my AIO can handle 2 more blocks and a extra 120 rad, might have to get a Swiftech H240-X if I can find one in stock somewhere (only found H220-X's in stock). finger's fine, it hit my fingernail. On the bright side, I discovered this card was the one holding back my OC. strange since it's the higher ASIC one. Or maybe combined power draw? headscratch.gif hmm

I'm sure we've all done this at some point >_>

Lol yeah, but it does the ♪wobble wobble, shake it shake it♫



━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Thinking of buying another STRIX 970 from Microcenter with extended warranty w/ accidental damage coverage and swapping cards. they do full refunds no questions asked. would this be wrong? lol.

I was ready to eBay both my STRIX cards to buy some reference nvidia ones from bestbuy with titan coolers cause the top card roasts at 78c with fans blasting on hair drier mode due to hot air circulating with case panel closed. but now I dunno especially after I have one card b0rked. they probably wouldn't OC as high, but that vapor chamber titan cooler is really the best. Can't seem to find any pictures of the actual reference nvidia-sold 970, looks like same PCB as 980 but perpahs with a phase and a few mosfets cut off. (12 instead of 18 mosfet on the MSI reference design version but it's brown PCB. not sure what nvidia's black 980 PCB version has on their 970).

What's holding back my STRIX's right now is VRM temps (117c I saw at one point) and for some reason with two cards it senses 12v input at 11.5v under load, but with only one card installed it senses 11.9v under load even though my multimeter on a molex plug says 12.22v. I see a 12.15->12.10 drop with voltmeter directly on PCIe connector with one card, have to test with two... strange, maybe my 750w is not enough? headscratch.gif it's a quite durable CWT-built design like the old Corsair PSU's (TX750, HX750, HX950) before they switched to seasonic, with 7yr warranty. harwaresecrets managed to pull nearly 900w from it without much drop. or perhaps it's my motherboards 75w on two cards drooping too much?


Edit: I edit too much.

Until I manage to resolve this I increased P00 voltage so it does not drop to those unstable minimal values.

Do you happen to know tha ratio I should use to increase voltages? I mean if I increase boost table by 3 clicks, should I increase voltages by 3 also or more or how much? So far I have been unable to determine the ratio.

I just wanted to chime in and say I'm not so sure it's ASIC related, or if it is it's across the board, as my card's ASIC is 77.3% and experience this same issues. This is why I changed my P00, and recommended to others to do the same as a "catch all" fix. Yes, I'm aware it's not the most elegant or efficient. But it works without fail and I don't have to watch tons of boost clocks and voltages, try to scale them, and flash the BIOS god knows how many times. So until we find out what the cause is, or what an appropriate ratio is for the voltage tables, I'll be sticking with it.
