What happens if I dont calculate the %/RPM?

Why I have to set a min-% Value? I entered "17", but in AB I can go to 16% (makes sense, because 625/3900 equals 16)
But why I can enter such a percentage value?
The fan curve goes well from 625 to 3900, thats how I want it to do.

Yes, I want a whisper silent PC, without hearing anything in Idle. Load noise isnt relevant that much.
I wonder that the GB 980Ti Xtreme is quite quiet with 625RPM, so I dont need the "FanStop" thing..
With 23-27,5°c in my room, I have an Idle Temp from 40-43°c with my 5820k (+150mV Offset), thats ok I think,

As you already figured it out yourself with that little math calculation there - that 16% value from the bios shows up in MSI AB, where values have to be correct otherwise when you set up a custom fan curve in AB it will not be correct in achieving the temp(s) you're shooting for.

If you want to run the fans continuously, do so, but keep in mind it will reduce their life span. Keep in mind they were designed - and calculated - to run only from 60C on upwards. Do a search right now and see if you CAN source a replacement fan for that factory cooler....

You will also see a lot of dust build up on the cooling fins after a couple months - that will reduce the cooling effectiveness of the factory cooler, and to be honest , if you don't own a compressor (set on low!!!) to blow that stuff out , at least monthly, you will see a 3-5C loss in cooling efficiency over a six mo to 1 yr. Canned air will not blow that out effectively, trust me, I have tried.

Did you check out the thread about fans that Liathan posted?

Also, do not compare temps from a CPU to those of a GPU. The GPU develops higher temps - but at the same time can take higher temps without errors compared to a CPU.

From a temperature vs efficiency (and for me, overclocking) standpoint and noise (for you) I would consider a custom water loop.

I am saving for that as we speak, even though I can hit 1600.2MHz stable on Liathan's bios ON AIR.

Meh,

I can hit 2.1Ghz on air!

(will be on water very soon)

I saw a world record submission using AIR that beat an LN2 score. Maybe it was just a bad LN2 attempt or they picked LN2 and didn't really use it but either way we are talking about a GPU on AIR... #1 spot... there were some on H2O also in the list.

It seems that it's really just silicon lottery that will deterine if you can overclock to 2050Mhz or 2200Mhz (seems to be average range) not cooling method or voltage. It may still be too early to claim that as fact but it's what I see. Anyone see any different? I have yet to see anyone post before/after stats demonstrating that additional cooling helps reach a higher overclock. It may help MAINTAIN the same overclock better but I don't think increase it.

Perhaps someone could do this (before/after, min 3 runs averaged, etc).. Use Unigine Heaven as it's more accurate for scoring.

Laithan, did you take a look at that LN2 bios I posted a few days ago? (Xtreme Gaming)

Just from looking at that one I can tell that for this chip more can be achieved with more V. How much I don't know since I'm never gonna LN2 ( "Do you even LN2 BRO?" tongue.gif )

I so wish that we could extend up the boost table of the MUMOD higher than 1455, I have a feeling that would give more than the 1600 I'm getting right now (BTW that 1600.2 is for benchmarking only, I run a more conservative OC for daily use that boosts to 1555).

When I get my water cooling I'm gonna try the waterforce bios and see what that does, (I had half a brain to try it now, on air, since it gives more V)

Oh and I definetly want to try to flash another "regular" - higher volted bios over the LN2 one and keep the factory one in the first position (for warranty purposes) , I'm sure the card has two Eproms that can be flashed separately - NOW THAT WOULD BE AWESOME!

What do you think ?

What do you think ?

No, I did not because there's really nothing to gain by using it unless you are actually using LN2. If it could be marketed as a "better overclock" I am sure they would have but the truth is, it's targeted only at LN2 world record benching.. smile.gif

The boost table doesn't give you higher overclocks. If you want a higher overclock, just increase the core MHZ.

I know what you're saying but it's not going to work like you think. It's not the purpose of the 2nd BIOS to have an "alternate configuration" from the first BIOS it was made for LN2 (it's quite clear and specific).

You can try to push more voltage as a test but don't get too excited, it MOST LIKELY won't help on AIR. It's been proven that GM200 chips and VRMs simply encounter thermal issues with higher voltage on AIR. I proved this a while back when I measured maximum stable overclocks using the exact same GPU both on AIR and on WATER using the same voltages. I was thermally limited WITHOUT adding additional voltage and once I put the full cover block on I could overclock higher using the same exact BIOS (which isn't a surprise but confirms it was a thermal limit directly involved on the VRMs).

If you want to push higher voltages on GM200, consider water cooling as a pre-requisite. Trust me on this one. wink.gif

Yes each BIOS is separate and could have different MODs but there's no point really. You just won't gain anything from using the LN2 BIOS, you may actually lose since it's designed for sub-zero temps and I mention the MEMORY HEATER (which I am NOT SURE if the xtreme card has or not I don't see much about it) but you certainly wouldn't want to be using that unless actually on LN2 as it's for the "cold bug" that's common with LN2.

Lastly, the (2) 8-pin connectors are modified to provide 200W of power each. That's 475W total power compared to stock 375W. You are already getting the additional 100W (or 108W to be more accurate) possible if the additional 6-pin was used without the need to use it thumb.gif Additional power won't help when the GPU isn't starved for power, there's more than enough with 475W for both AIR and H2O.

cheers.gif

PS. Note not even a waterforce will gain anything

I didn't mean to use it as a regular bios without actually using LN2, I just meant that I looked at the voltage values and ranges, and the chip can take more V no prob (obviously with better cooling than air)

So how does GPU Boost 2.0 use the boost tables? (I'm not contradicting you, I just want to learn the mechanics of it)

I know this, BUT , If I have two Eproms flashable separately, why not make use of the second one for two configurations on a hard wired switch? I'm not even talking here about the extra power cord. Just the convenience of having two custom bioses I want to have on there?

Gotcha. It's something logical and normal, especially since , after buying the card, i noticed thermal throttling above 64C. I will test a little more V, Maybe just to 1.275V, see what happens. See - I have this A/C unit right in front of the PC, my ambient is at 19-20C specool.gif - and I have three extra high pressure corsair fans blowing on the card directly. Just for testing - of course- I am saving for water cooling
I just specced what I want in EK products and it's like 1200$ O-O

That is exactly what I want , not using the LN2 feature, just having two bioses loaded that i can switch between. Now the MEMORY HEATER thing - if it has it - would be detrimental to that of course, is there a way to figure this out by looking at the pcb ?? any electronics wizards around here?

Anyone? Anyone? Bueller? biggrin.gif

So this may be a stupid question but does gpuz or any monitoring software read the core voltage if you have it above 1275? and if not is there a way to check and make sure of the voltages I apply in my bios mod?

Nope, software monitoring stops @ 1.275v (GM204) and 1.274v (GM200).

You would need a DMM and know where to measure which is very difficult since the areas are not exposed. However, It's well known and proven though that voltages on any Gigabyte GM20x cards that voltage is not locked and can be raised all the way to 1.3v+ (but that's way too high).

OK that's good news because I'm at 1.281v now and still sitting at 70c wile stress testing so I still have some headroom temp wise especially if a get a second card and watercool. Thankyou for the answer.

And actually I do have a dmm so if anyone knows where the voltage check is on a 970 g1 that would be awesome.
