gtx660TI clock stuck at idle freq (324MHz)

[quadlt]

u running more than one monitor? if yes that could be the problem I have seen some cards don't downclock when there is more than 1 monitor connected.

Nope, single monitor. Ironically, after I posted that reply and gave up on my semi-dead GTX 690, I found a FIX!!! I bet this can be applied on all Kepler cards that had this stupid 324 MHz issue. I downloaded KBT and screwed around with different clock and boost speed and my dead GPU1 started showing daylight! After hours of playing around with different number (I still have almost no clue which numbers should I change properly) I am able to use both of my GPUs in their full potential, well almost. The faulty GPU won't auto-boost properly, has different speeds in Afterburner than GPU2 and hell knows what else, but I've been able to run them both at stable ~1100 MHz speeds. I've attached a screenshot, as you can see GPU2 (the non-faulty one) freaks out sometimes with boost clocks, but overall I can finally enjoy proper SLI GTX 690 gameplay! I'm also uploading the current modded BIOS that I'm using to achieve this. NOTE: I'm using EVGA bios on an ASUS GTX 690, so it doesn't really matter what vendor did you get your 690 from. NOTE #2: Once you flash this, your both GPUs will behave differently and will have different clock speeds. Play around with MSI Afterburner (or your favorite OC software) to match clock speeds. Also don't forget to modify GPU1's voltage as it doesn't boost as well, don't touch GPU2's voltage though! WARNING! This is an unstable BIOS and I am not responsible for any further damage to your video card. Flash at your own risk! MODIFIED BIOS HERE. Flash with nvflash. If you own a different model card (not 690), use this as an example to play around with your own BIOS that you can find HERE and I'm pretty sure your GPU should come alive. Hope this helps anyone who still owns a faulty Kepler card or has just bought a used one, like I did.

well done on finding a fix, so its BIOS related?

Could flashing another stock BIOS fix it?

That would achieve nothing. As I said in my 'tutorial', I'm using a modified EVGA's BIOS and before that I used the stock EVGA one, which didn't help me at all. I don't think it's a BIOS problem, I think it's the cards that are reading impossible TDP values (presumably due to a defective part of the card) which start throttling. I'm still getting a lot of crashes while running both GPUs to their knees, but at least it's not a dead GPU like it seemed before.

I follow what quadlt done.

the problem is the card just set the clocks for pf 00 State (idle state).
Because there's a problem on a sensor that read the perfcap, and cause this issue (limited to total power limite)*.

The first time mine was showing something like 143% and when i set my fan to 100% it shows 156%.
So if you can disable this function maybe you are able to up your memory and gpu clock.

I tryed to flash my card with another stock bios but it failed.

Thanks quadlt for your help.

So you have the exact same problem that my GTX 690 had. Did you actually try modifying your stock BIOS? Or did your flash just failed? Could you provide the model of your GPU? I could try modifying its BIOS for you.

Thanks for support bro. I've done a custom bios. From my original .rom now it's working but i cant run flash player because it give me a bsod.

Really appreciate your help. When i finish it 100% i'll post my .rom here.

It's a 660ti.

I've recently found out that you don't even need to fiddle around with clock speeds. I started changing my Power Table to random big numbers like 700000 (which would equal to 700W of power) but actually the TDP dropped down in Afterburner, so now it's for sure confirmed that a part of GPU which reads power is defective. Once I changed all of the numbers I can finally play without both GPUs boosting differently, they actually work together as they should now, but I can do minimal overclocking. Anyway, I can't really help you with Power Table editing since it's different for every card, but try increasing all the numbers like I did and eventually you should see that Power % dropping. Good luck.

Also, here's a new modified BIOS for GTX 690 which boosts and acts normally: DOWNLOAD. Though be careful again, since your card might have different power readings and this might not work. And don't do any crazy overclocks over 1100 MHz or you'll end up with a driver crash or even PC freeze. Here's a quick tutorial for how to fix things:

• If you want to lower the GPU power %, increase the numbers which start with 4 in this BIOS. (I'm pretty sure you don't need to touch the other ones, but my GPU power doesn't change if I don't increase them)
• If you want to increase the GPU power %, lower the numbers which start with 4 in this BIOS.

At least that's how it works for me. Good luck to anyone trying to resurrect their old GPUs!

I get your bios and set the same values as you said and it really fixed my problem thanks bro.. I spent a lot of time trying to create a lot of custom bios but i had a lot of blue screens.

So i use the same values that you set on your Bios and it worked fine. Thanks Again.

I forgot to say i was using kepler 1.25 when i upgrade to 1.27 it worked fine.

U really found a fix.

Someone should sticky this or perhaps drop the posts with the fix in a separate thread.

I get the feeling we are going to get more of these cards in the near future, Kepler v1 is aging now.

Glad to hear that, happy gaming to you!
Also, could you upload your modified BIOS? I'm thinking to add modded BIOSes into one thread later. PM me if you can with a download link and some basic info (model, what was your power % before modifying, power % after modifying, maximum safe overclock if you tested). Thanks!

If a mod is willing to sticky my post, I could make one with all the things necessary to fix a GPU.

another mod may choose to unstick it later if it doesnt get much attention or traffic, but its up there for now.

GTX Stuck at 324 FIXED

Hi People,

I have the same problem here with an Asus GTX660. RMAs and swapping out parts isn't really an option here, i do seem to be getting somewhere with it though! If someone can provide a deeper insight into these BIOS settings, and how they inter-operate that would be great! Also this may help someone with the same predicament. This particular card had softdrink spilled onto it, may or may not be related :/

Everything seems ok with this card to begin with. Boots into state P08, but shows varying over TDP percentages 112% - 300%, even though the card is showing it's receiving 875mV, which is spot on with what it is meant to be getting at that clock/power state when you look in the BIOS with an editor.

Launching a game or 3Dmark I noticed also that the card was locked at 324 Mhz, (i didn't check whether it changed power states, i'll provide more info soon), memory clock was very low also and performance was terrible - scoring about 3000 in Sky Diver, 15 Fps, with an i5 3.4 Ghz.

I did read this post - http://overclocking.guide/increase-the-nvidia-power-limit-all-cards/ and thought that if i performed this the card wouldn't think it was over powered. It didn't work, actually I had the reverse effect, with the card showing 700-800% Power Consumption, whoa. I popped the little solder blobs off after this, (back to stock), not sure where i went wrong here..

Grabbed the Kepler BIOS tweaker and started having a look. If you're in the same boat as me, there is no chance of an RMA. Please take care, this may not work for you, and really, i don't know exactly what i'm doing.. Also this card would still work fine in a media centre or something in its current state. I needed it for 3D, and i didn't really care if i fried the card in the process.

Firstly I looked for occurrences of 324Mhz, there are a few. After a few trial flashes to check results, I ended up just changing Boost States, and Clock States tabs.

Stock Boost States are the following

I changed all the values of the P08 Profile to match the P00 profile for boost states.

On the clock states tab, do the same,

Make all the values for the P08 profile match those of the P00 profile.

After flashing this modified BIOS I noted the following:-

Core Clock was 549Mhz, Memory was 3004/6008, Card was receiving 950mV, and no PerfCap Pwr reason! in P08. Randomly did get perfcap reason "util" but didn't hold the card back when it changed states to P00.

Using afterburner initially I was now able to overclock the card to 715Mhz up from 549.
(Before loading the modified BIOS none of the software I tried was able to over clock the card from 324Mhz.)
Then using nvidia inspector i was able to get the card to 900Mhz with a 50mV boost.

Ended up pulling 12596 in sky diver!

Really pleased with the result, temps are good under load and it seems fine! Probably runs a bit hot for normal 2D but i think that is acceptable for a nearly 400% increase in performance. Also i'm sure with more effort i'd be able to get this card to perform as it should with speeds of over 1Ghz. Glad i didn't give up on it Anyone who knows what's actually going on here, let us know? Hope this helps someone also!

Cheers

Looks like you reinvented everything yourself, haha. Take a look at my thread, it should help you better. While I did play with clock speeds initially in BIOS tweaker to fix my GPU, it is not the optimal way of fixing this problem (however, it might be the only solution for you, but I doubt). Try playing with the Power Table section like I did, to make the card TDP % go down and then it will behave normally. If you run into any trouble, be sure to hit me up on that thread, because this one is not really the place for that.

EDIT: Also, if you manage to fix your GPU, please be kind and PM me your edited BIOS with some information (model, what was your power % before modifying, power % after modifying, maximum safe overclock if you tested) and I will upload it on the thread to hopefully make things easier for others. Thanks!

I tried to solve this problem by testing different bios to unlock the idle time and this one fixed the problem.

Sorry to necro-post, but I have a related question and this seems like a great place to ask.
Got a situation with a GTX660 where the card on the desktop runs choppy and stutters a lot. Determined that the P08 default clock speeds are just too low for the triple 1080P monitor setup it's connected to.

Would it be as simple as copying all the P02 or P05 values into P08 entries on the "Boost Clock" and "Clock States" tab, or is adjustment also needed in another tab? The owner doesn't OC and is happy with the default voltages & boosts.
