ULTIMATE ASUS MATRIX PLATINUM GTX 980 TI AC/LN2 TIPS

[Gunslinger]

Got it working with the latest from the website

[marc0053]

Thanks for the great guide!

 

I received this card last week and it's been an incredible experience so far.

I did the LN2 enable mod with simple pencil lines to make the connection.

 

On air I was able to get between 1550mhz and 1590mhz depending on benchmark with 2150mhz on the memory (Hynix)

 

I added a EK thermosphere waterblock and get around 1600 to 1620 MHz at stock volts and see no change up to 1.35V.

1.35V+ tho the card started scaling up to 1.52V with up to 1690mhz in firestrike on ambient water of 21 degree C. ASIC is 84%.

 

Here are a few subs and pics.

Would definitely recommend this GPU to anyone.

Wish mine scaled like that, I tried pumpin her with 1.4v, but it wouldn't do past 1550 still.

 

It does 1550|2275 in FSE no problem 1.231v core, ~1.7v mem, but doesn't seem to go any higher.

On water btw ^

[hotrod717]

You got a real nice card there Marc.

[Wizerty]

I tried mine today.

 

Card can do :

1510 FSE stock cooler (LN2 bios)

1520 FSE with AIO (LN2 bios)

 

1750 FSE 1.55v

1850 FSE 1.65v

1900 FSE @1.7v (load) -100°C

Lowering T° to -110 and thing get worst.

 

Mem is Hynix.

I get 8800 stable with 1.75v few minute, then 8600 for hours, and then in 20seconde I loose 300MHz and had to bench 8250 or less.

Might want to try some sort of memory heater. GTX 480 hair dryer still available?

[Rauf]

It has memory heater built in...

 

Seems you are unlucky. 8pack tried several hynix cards at the sheffield event and all did 2000+ pretty easily. My samsung can bench -130 no problem.

[hotrod717]

Question, if I update to new ln2 bios and do recovery, will it revert to original ln2 bios or updated bios?

I'm in agreement with Wizerty. 1800/2100 is fine up to -90*c but colder than that, I get issues. Hell, it will do -150*c but doesn't help.

[Rauf]

Also hynix? Mine scales to at least -130. Didn't try lower as I wasn't pushing for fire strike and I didn't think it would be likely to go much colder anyway.

[Gunslinger]

another dead Matrix for me

[Rauf]

How? You must have killed a ton of hw lately

I simply flipped the bios switch while in windows, I heard a crack like a LN2 pot makes, and bye bye GPU. Stock cooler, stock clocks, stock volts

Samsung. Maybe I just need to push pex a bit more to even out.

I did that once as I was shutting my PC down, fans ramped up super fast and it BSOD'd as it was shutting down.

I think there is something that adds massive volts when you flip the switch while the card is on.

[Guest Bullant]

Nice guide XA,so if buying one of these cards now is there still chance it be Hynix memory's?

[Dancop]

Not really

[Guest Bullant]

Not really

 

Ok Thanks,if I buy one hopefully has Samsung memory's

I just grabbed a strix with sammy mem. Do you guys think the matrix samsung ln2 bios would work ok, has anyone tried. I know I can just short the shunts but obviously an ln2 bios is easier.

 

There was only one posted for strix and I'm assuming it was when the card had hynix mem.

New LN2 bioses, improves memory overclocking. Also works for Strix 980Ti with Digi+ ASP1212 VRM controller, does NOT work with cards using SHE VRM controller. Ask if unsure.

 

m980ti_ln2t3s.rom = Samsung

m980ti_ln2t3h.rom = Hynix

OCP fix will not be made public since it's only needed at max freq on LN2 with 1.8V+. In any other situation it's not a problem and only increases the risk of your card being damaged.

 

Cold slow resistor on Strix v2

thanks so much for all your help.

[mahaudi]

I search a hardmode of Asus 980ti Strix V2 with Samsung Chips.

 

vGpu / vMem / vPLL .

Just thought I'd post an issue with that BIOS Elmor posted on here with better memory OC.

If you try to do GPUPI or any GPU compute benchmarks / folding, the card goes into P8 state for some reason, and downclocks to 405 mhz.

 

I just flashed the stock BIOS back on, and now it's working fine. Figured I should let everyone know incase they have problems like I did.

 

Hey Guys, I'm also having this issue when running GPUPI or ASUS Realbench that the card and volts downclock to 405 MHz and volts at 1050mv but goes back to normal when the bench is done.

I'm using the latest LN2 bios for Hynix memory posted by Elmor here and have the bios switch to the LN2 position. I enabled the LN2 mode using the pencil method and the GPU is under water cooling. I didn't have problems with any other 3D benches other than these two so maybe something to do with openCL stuff?

 

@elmor Since this doesn't happen on the stock bios would there be a easy fix for the LN2 Hynix bios?

Can you try first using NVPM or GPUTweakII to force always 3D and see if the clocks stick then?

I've done all of those things, none of them work. It's something wrong with the BIOS, when I switched back to the stock one, it worked fine.

@elmor thanks for the Quick reply

 

I tested both NVPM V1.1 and "Always 3D" in GPUtweakitII and they both seem to throttle memory and core clocks down to 810MHz and 405 MHz, respectively.

 

Attach are 2 screenshots of each methods.

 

Once I close GPUPI and or ASUS Realbench openCL the clocks go back to boost.

 

Always 3D
