On crysis and metro LL & fc3 I got throlling because of the tdp : gpu's are flapping between 1150 MHz and 1274mhz

Wish it could help tuning your beast up :-)

Gtx 690 Oc roundup:

http://www.gpureview.com/gpureviews-gtx-690-overclocking-roundup-article-945.html

How did you get the voltage that high on the 690?
Ive used the KGB unlocker buts thats as far as ive got...30mhz increase on boost clocks.
Whats the best driver for a stable overclock?

Card reaches 48°C max. on these volts thumb.gif
How did you manage to get your voltage that high on the 690?

Just grab some .5mm thickness from FCPU, and look up the manual on line for the koolance block to see where to place these on the pcb. You will have to cut the thermal pad to size, which is no biggie. I did the same for all my Titan blocks.
You will like your water cooled 690 much better than the stock cooler.

Edit: make sure that you save the thermal pads from the stock cooler. I always put the stock thermal pads on the stock cooler, after taking it off, and then wrap it in a plastic wrap and put it away. I also take a picture of the pcb with the stock cooler off, before putting the new pads and water block on. This provides a good reference point of how to put back the stock thermal pads, in case you have to do an rma.

Thanks thats good advice.

Answer with ease : "rewind" the thread tongue.gif

your lucky m8 im a good man : SEMPER FI


to sum up Power Target maxed out :

can raise it higher like 500% value in a bios editting software like KGB (but value is capped to 169% in my case when monitoring the right value) / and of course it will break the PCI EXPRESS specs for sure ( max 8+8 pins= 375w= 150+150+75)

new TDP between 380 and 475w when overvolted : need STRONG PSU


Try this guide , Its easy to follow as long as you follow everything correctly.

My GPU's both go over 1200mhz when overclocked now which is great. --) TDP tricks !

(Ive also updated post no1 with this guide)
Flashing bios instructions for any Nvidia Keplar GPU.
YOU DO THIS AT YOUR OWN RISK

I wrote this guide as i couldnt find one anywhere.

First of all, You then need to download these files.

GPU-Z (This is used to grab the original Bios from the Gpu wether multi or single)
http://www.techpowerup.com/downloads/2181/mirrors.php

KGB - Kepler BIOS Editor/Unlocker. (This is used to modify the Bios that you just grabbed from your Gpu using Gpu-z)

KGB supports: GTX690, GTX680, GTX670, GTX660Ti, GTX660OEM and GTX660
https://www.dropbox.com/s/vrunxuq03vj0m5y/kgb_0.5.zip

NVFLASH (This is used to reflash or reinstall the new modified bios)
http://www.softpedia.com/progDownloa...oad-16133.html

Steps 1-10.

1.Ok what you need is firstly to make a USB dongle bootable into DOS, To do this read this very easy to follow guide.
http://www.bay-wolf.com/usbmemstick.htm

2.Run GPU-Z and and click on the icon that allows you to grab your bios from the Gpu and save it to your PC.

Also make sure you have a copy of your bios!!

3.Once you have grabbed your bios put it into C:\Users\My and rename it 1.rom

For example the bios from the GTX 690 Gpu 1 is called GK104.rom, I renamed it to 1.rom and the bios from Gpu 2 I renamed 2.rom.

The reason why you should put the bios in C:\Users\My is because the default path will be set here from KGB.exe so if you are not familiar with the CMD (Commandline) then this is the easiest way of doing it.


5.Take the KGB.exe as well as the KGB.cfg file and also place both of these in C:\Users\My.
You should now have KGB.exe, KGB.cfg and 1.rom files in C:\Users\My.

If you have more than 1xGpu then you will have 1.rom and 2.rom respectively in C:\Users\My.

6.The next thing to do is open up the CMD (Commandline) which im sure you all know how to do.
Once you have the CMD open, Copy and paste in this command.

kgb 1.rom unlock (press enter).

It will now save the new values (i.e. from kgb.cfg) in your bios then print out the new values in the bios.

7.Now all we need to do is put the new modified 1.rom back onto the gpu, To do this we need to use the USB DOS bootable Dongle that we created in step 1.

Take the nvflash files once you have extracted them and place them onto the USB DOS bootable Dongle, There should be 2 files.

Then place the 1.rom bios also on the USB DOS bootable Dongle.

8.Now the Dongle is ready to be booted from so reboot the PC and go into the bios.
Once you are in the bios make it so the PC boots from the dongle, Once this happens you will then have a flashing cursor telling you that you are in DOS mode.

9.Type in nvflash --list (press enter)
This will then tell you what gpu(s) that you have installed on your motherboard.

10.Type in nvflash -i1 1.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.

If you have a second gpu with 2.rom.

Type in nvflash -i2 2.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.

Once this is done reboot the PC go into the bios and reset your boot so it boots from your hardrive with the Windows OS on.

Once you get into windows you can see from MSI afterburner or EVGA precision that the power target can be raised from 130 to 150.

When gaming the boost clock should be higher depending on your GPU.

I achieved around an increase of 30 on the core clock on boost alone on both GPU's which is very good.

It will differ for each person and each GPU(s), You can also try other peoples bios as long as iyts the same GPU as your own.

You can also modify the KGB.exe and tweak power settings for even more results but I wouldnt advise this unless you know what you are doing, I would just leave it at stock and use that for the time being.

Everything you do is at your own risk ! ! !

1.3V UNLOCK VOLTAGE : http://forums.guru3d.com/showpost.php?p=4638716&postcount=22

NCP4206 is also used on many modern NVIDIA reference design cards (Titan, 7x0 and some 6x0). MSI don't provide official voltage control via NCP4206 for such cards, however you may try to unlock it by adding the following strings to hardware profile (.\Profiles\VEN_10DE......cfg):

[Settings]
VDDC_Generic_Detection = 0
VDDC_NCP4206_Detection = 3:20h

You can easily verify if your GPU is powered by NCP4206 even without the profile modification using the following command line switch:

MSIAfterburner.exe /ri3,20,99

This command reads NCP4206 ID register, if it will display "41" value - you can unlock direct voltage control via NCP using the profile modification trick mentioned above.

proof :


1.3V seems a bit high for 28 nm process with air cooling for long periods of time, under WC should be ok.

quick bench ....

lascar - appreciate the effort mate thumb.gif
+1 from me.
I'll have a crack at my 690 over the holiday.
Got a water block to install on it yet.
post #5124 of 5564
I made that guide, it was me, the KGB one that is.

So if i follow the other bit at the bottom and put those values in, i will be able to raise voltage power on the 690?
Is it possible to do the same with EVGA precision?
Cheers.

Cheers.

yeah try this :

open x:\programfiles\MSIafterburner\Profiles\


if u set a profile and save it : you should normally had the following strings in here : "VENXXX.cfg' and other VENXXX*.cfg
for example :

VEN_10DE&DEV_1004&SUBSYS_104B10DE&REV_A1&BUS_1&DEV _0&FN_0.cfg
VEN_10DE&DEV_1004&SUBSYS_104B10DE&REV_A1&BUS_2&DEV _0&FN_0.cfg


if Not please set STOCK SETTING in MSI AB : STOCK SPEED , POWER TARGET TO DEFAULT AND FAN SPEED TO DEFAULT ALSO

save the settings in profile 1 for instance. !

Close ALL MSI AB TABS , and the software itself
Add in the bottom of any configuration file the following part:

[Settings]
VDDC_Generic_Detection = 0
VDDC_NCP4206_Detection = 3:20h

So you have to do it on each *.CFG you will have in the Profiles directory.

Now if everything is cool, next time you'll restart MSI AB, a popup window will display with the sentence " You should restart the computer otherwise MSI AB will not detect properly the speed and the fan configuration ...... "

click on "NO" ( U don't want to restart the pc, indeed you prefer forcing the detection right now !)

MSI AB wil pop up briefly disapears and pops up again... (look at the voltage tab) : AUTO should be written, moving the slider will display REAL VALUE in starting from 0.80V to 1.30V maxed out

And sadly noway it works under Precision, because MSI AB was made from the original scratch of RIVA tuner software (made by UNWINDER) , PRECISION is more like a bootleg version 8-) ... not the same DEV.

Guys, I've analyzed NCP4206 voltage control feedback in different forums and noticed that many users treat current implementation as beta and expect "improved" NCP4206 voltage control in future versions of Afterburner and expect to see voltage drop in idle. It won't happen, current NCP4206 voltage control approach is the maximum that you can expect from this chip programmability. NC4206 supports either external voltage control via VID pins, when driver sets desired 2D/3D voltages via GPU Boost or voltage override mode, when fixed voltage is set 24/7. So there won't be any improved version with power management enabled, sorry. "

It won't work in Precision. Furthermore,

Precision won't even display altered voltage on the graphs because it is coded to read voltages via NVIDIA driver only, it doesn't support direct access to VRM like Afterburner does.

Comments given there are plain wrong. AUTO is not AB mode, AB doesn't take any control on voltage regulator when AUTO is selected, voltage is driven by VID pins of NCP4206 in this mode. And nothing is broken there. The only change with default voltage control (which is taking place when no CFG edit is applied) is that you see VRM output rather than target voltage on the graph.
BTW due to such comments we locked direct VRM voltage monitoring via CHL8228 during RADEON 7970 launch. Seeing LLC on output voltage graphs is too confusing for many users and results in stupid claims like "AB drops voltage".

Having some problems, i installed the koolance block which is ok my temps are both pcb's at around 35 degrees. As soon as i run uniengine my temps go over 100 degrees on 1 of the pcbs. My radiator is as an mcr 320 triple rad. I had better performance with the air cooler if im honest, the bottom of my radiator gets hot but the rest of it is cold, i wonder if i have an air bubble trapped in there, i have eliminated all the bubbles tbh. I may just put the air cooler back on and **** the block back to where it came from. Totally pissed off if im honest.
post #5130 of 5564
One core spikes +100 ? Probably not good contact between chip & block

also, if your rad only gets luckwarm or "hot" only at the bottom.... you might not have circulation.... check the pump , check flow, and yes.. check if you rad is not half filled with air.

Anyways, a 360 rad is barely enough for what is basically TWO GPUs... following the rule of 120.2 per device



Ps: since i'm not seeing it in your sig... you DO have a pump i presume ?
