okay nevermind.... black screen at stock
MSI
you...

crashed after like 10 minutes


on oc'd setings, heaven and 3dmark11 pass no problems

CS GO crashes INSTANTLY

something can't be right


Well it doesn't crash if I take my oc off, well not right away anyway.

You guys think I have a defective card?


EDIT: It doesn't crash if I don't have any oc program running. Like even if I am not oc'd, they crash my GPU.

Still playing, but I'm at 1358/7250 on Heaven right now. I have the Asus D2C TOP and have done the BIOS mod to get 1.212v and 145% power. Changed the TIM to Gelid GC-Extreme. Also removed the stock fans and strapped (2) GT-2150 fans on there for slightly cooler temps. Max temp is 55°C.

I've been running Crysis2 benchmark (DX11 + HD Pack) to get more game stable settings. I think I'm getting close at 1344/7250, but this may change as I game more and ambient temps change. Crysis2 is stable at 1358/7250. Played for a couple hours last night w/o a hiccup. Temps maxed at 47°C.

3) Two things could be happening here. Case one is that you were lucky to finish the benchmark the first time, and case two is that you're going through a burn-in phase where your card requires more voltage to stay clocked the same. (Kinda like the Sandy Bridge CPUs. I don't believe in hardware degradation.)
What is your Max Boost (Boost Clock + Kepler Boost) at +101 Offset?

You don't believe in electromigration? It's not a religion. rolleyes.gif

So I'm new to Kepler...
Using evga precision I've found out a few things with my 670
The voltage tuner doesn't work....no matter what voltage I set the tuner at, its locked at 1.175v when under load...
The Power Target doesn't do anything too. I can set it to 75% or 122% and neither do anything...
The only thing that really matters for my card is the core offset and memory offset.
Is power target or voltage tuner for something relating to temperatures if they become an issue? My card under water won't go over 35C and I I've found the voltage tuner and power target to be completely useless...

Voltage Tuner doesn't work the way you think it does. It's been mentioned several times in this thread, but it will always go to 1.175v under load. If you select 1.175v in VT it will stay locked at 1.175v under load whereas if you select something lower it will drop the voltage when load isn't as high, but still go to 1.175v as the max. Locking it at 1.175v usually will be your best bet, but if your speed keeps dipping under heavy load with power % maxxed then it is advised to try and reduce the VT slider to lower power %. This might keep your clocks high, but also may introduce instability. VT does something...just not much.

Power Target works too. But if you're not hitting the max it won't matter. If you're hitting the max then you want to increase it, so your max is higher. wink.gif

The colder the temps are the lower the power % will be. Your temps are so low there is basically no effect since you're not hitting the ceiling. What is the max power % your hitting in the graphs when running Heaven or 3DMark11?

Hello


I appologize, if this is not the right place to ask my question...but I think its right here.

Yesterday I tried your great 30minute guide very carefully but finally I decided not to use the new settings, as I did not feel a big difference. :-) Ok maybee I was too carefull..;-) however, its my first time to oc. All the time the OSD was active and I was able to SEE that the temperature never exceeds 66°C. Finally I decided to reset all settings to default and I tried to optimize the software-controlled fan (by using your hints) a bit to find a silent mode for me. I found some nice settings and wanted to test them finally in GW2. The temperature was ok but I wanted to give more tolerance to ensure no overheating. I used alt-tab to switch to precision but during this context switch GW2 crashed. I restarted GW2, but the OSD showes that the fan is on 10% by increasing temp! Of course I stopped GW2 to check out what I did. I tried to activate the hardware fan controller in precision, but it did not work. At the moment it seems that my card only will survive with software controlled fan. :-( not good. Is it possible to deactivate the hardware controlled fan? Just in case that precision crashes or I forget to start it...omg..dont think about it. Please help! I bought this card just three weeks ago and hope ... that it would be changed if it is a defect instead of a human failure. Thank you so much!

Seems like you may have the same issue as I'm having.. except my card crashes in heaven as well.

My 1st post.

I just got my 2nd EVGA GeForce GTX 670 and I'm running the Heaven Benchmark. I have the Logitech G510 keyboard with the LCD screen and I'm seeing my 2nd GPU running 10% higher and about 8 degrees higher than GPU_1. GPU_2 hit 72 degrees. Also I have the 2 cards "SYNC" turned on in Precision X and everything turned up in the NVIDIA Control Panel. In the Overclocking where it says to
increase the offset to +120 so the GPU clock reads 1100MHz, I type in 120 or even higher but the MHZ stays the same. Before I got the second card I got it to 1100. I don't know what's up with that.
But anyway, can I get some advice on how to proceed?

Thx,
Dave

It sounds like your drivers crashed, software acts weird when they do and you have to close and reopen it to fix the problem. You can simply uninstall it if you do not like the hole fan curve or uncheck "Enable software etc etc control"... which you have unchecked, which means it is using the manufacturer fan profile.

Gwgeek, dial down the OC for gw2. As an example, my heaven clocks are 1280/3649. For gw2 I need 1267/3600 to be stable there. I found that different programs handle the GPU OC differently to be stable. Heaven and 3DMark11 are not the absolute test of GPU stability at a given OC. Always play your games to validate the OC and adjust if necessary.

When you have a driver crash, especially a bad one, in gw2, you may have restart the game at a minimum. I have seen performance come back are going into an instance or through a portal/waypoint. YMMV. Good luck! thumb.gif

hi General123,

thank you for replying!

I deinstalled and reinstalled the actual nvidia driver..as supposed..no changes.

Just to clarify, I posted two setting:
1. Software-Fan controlled active: everythings works fine.
2. Hardware-Fan controlled active: fan stucks at 10% ...not fine.

Question:
1. Does some one had the same problem?
2. How to check whether the hardwarefan-controller-chip is damaged?
post #990 of 3357
Hi nismofreak,

thanks for your replay,

but..actaully NO OCs are active nore they have been during the crash(!). My setting are the defaults. HOwever, at the moment I have to use a software controlled fan in order to provide any cooling :-( :-( ^^

greetings
