I'm measuring the voltage of the 6 big electrolytic core caps just above the memory with a multimeter. I can do this when the card is running using the older 2 piece heatsink with the memory/FET/inductor half removed, and just the core half in place.

 

Now through 7 Unigen Heaven runs at 1312/6930 (my 100% stable max overclock prior to this mod) and no crashes or artifacts.

Ah, got it. I Was trying to see how i would have to do it without soldering a temp wire in place.

So the current clocks at 1.062V? And is that the stock voltage for the card when running a stock test?

Overvoltage issue fixed. 1.062V vid is now 1.065V instead of 1.111V. I'm trying to see if I have a clock reduction. If I do, it's less than 10MHz, but so far it seems like none. Over 10% overall power reduction for the card.

 

Would anyone like a guide on the fix? It's just 1 resistor that needs to be modified.

Now don't take this wrong, but ummm.....quit asking silly questions! LOL

Of course we do! 

Question though. How are you measuring the voltage for the card?

ok. thanks.

@khenglish

When you repaired his gpu, did it over clock the same on your system?

The main reason being that they used 3500 mhz memory with better timings. (Desktop 980)

Hummmm, And when these gpu heatsinks get put on, they are actually sitting firmly on those mosfets?

Still trying to see if my mosfet mod did anything different. I'm still able to do the exact same numbers as before the mod.

And even the ones that came with the sky9 are bad also?

Exactly. And benching on room temp is a quick way to kill parts sooner than later though. It's possible to bench like that on room temp, but you run the risk of a lot of other things going wrong.  IMHO

I don't understand how your gpu score is so low for that overclock.....

And to add... No way a Sky9 should be beating your Panther.

No, all of them. The MSI 980m does not have backside memory.

Ah, got it. Thanks.

Going to test that 20k ohm resistor and see if mine is rated the same as well.

No, or else I would have done that instead of crippling a 970. Getting preballed chips also would have saved 75% of the total time on this.

And you only replaced half of them as well?

@Khenglish

Is there a place to buy just the chips themselves?

Yep, he is totally right about the cpu score. I just really noticed that just the other day.

Here is a 32.6k gpu score, with windows 8. And with windows 7 it was 32.3k

yeah i know, i only never checked how much total vgpu i got when i put the +137.5mv offset on, well then khenglish won the silicon lottery

unfortunately not me

He actually didn't win the silicon lottery. That came from a prior skillset he already possessed. And with a premamod to help push it even further.

It's alot less luck here than there is skill...;)

It's all to much voltage technically. And it has to have a balance. This trip, it might be base off of two mods. One for higher overclocking and one for lower over clocking, but with a higher performance rating on air. Just like what Vince did for the Kingpin Classified 980 ti.

 

For me, it's a work in progress..

That is why I made this post earlier....

Then it's getting closer.

You will lose on stock, but you can gain when over clocked.in the 1.5 ghz+ range.

But there is a balance though...

About what core clock did it start throttling at?

Good job!

Ivy Bridge still is no joke. With Skylake it is finally getting outclassed slightly in all areas, but it's still competitive. What annoys me about NBR are the moderators and the just the sheer number of people spamming worthless posts. You can go page after page in a thread with nothing worth reading.

 

Also I just took the 3dm11 top spot on HWBOT despite having a quad core CPU

 

http://www.3dmark.com/3dm11/10728576

 

1508/7500 clocks. Prema made me a special vBIOS set to 1.25V. This voltage seems to be the sweet spot with the throttling over 1.2V while still allowing higher clocks.

 

Also fresh driver install made things faster. 3dm11 is now showing the improvement it should with an extra 1.5ghz on the memory.

 

Now to try to get firestrike working again.

 

 

Now that is what I was expecting out of the memory upgrade! If that was done with a hexacore you would hold the top spot for sure there.

Yeah, unfortunately that is not going to happen at the moment. (undervolting lower than 1050V) without losing a higher voltage for later.

You should be perfectly fine at 1.05V for a 1.3 ghz or so overclock depending on temps. Memory varies. You could technically hit max on memory overclock, then dial back about 10 to 40 megahertz off of it. Depending on room temp.

hey guys,

i d also like to give my 980m some more volts than the usual 137.5 temp wise it can handle a lot more as is normally use 137 only for benchmarking is a completely new prema vbios needed or just some minor tweeks?

also it would be very great to have the possibility of undervolting und the lower states as my 980m never shuts off in the pm clevo and i guess for lots of other guys it woul also be a benefit als in the other clevo models the gpu isn t shut off anyways

Try setting it back to adaptive mode then restart the laptop. This should give you back the lower power and volts when nothing is going on.

All cards are different...

The 980Ms Fox is testing atm (no HW Mod) can't handle 1.2v and "already" blacks out @ some 1.175v...so he can't even test it.

Left all public GTX9xxM Mods @1.2v as that was already pushing the envelope for most people.

The mobile 980 Mod has 1.3v enabled for public, but also the 200W with their 7+1 power phases doesn't handle 1.3v too well, even though their stock voltage is already @ 1.1+ (depending on ASIC) and they use their native VRM voltage scales.

But since you are having the extra mosfets & caps, more voltage may be no problem.

 

Will send you the 1.4v later today:

1550 on both cards would do wonders right about now. Best i can do is about 1453 when running both cards. And the mod does not need to be permanent at the moment. It only needs to last for benching then it can disappear. lol. 

But on a serious note. I am thinking about that memory mod though.

400mhz with stock memory. I then voltmodded .05v higher for another 156 mhz. The memory change then got me another 380.

 

Pencil mods can go either up or down over time. With the 7970m I found my voltage first went up by .01v, then over time dropped .03v.

 

Hummmm, might be time to find some cheap 970's laying around with good memory.

Got it.

So with a volt mod alone you were able to gain 400 mhz on you stock memory or the modded memory?

And this pencil mod changes over time. Does the voltage drop or raise over time? And if so, by how much?

And I have people for that. 

Point me to the voltmod.
