Probably not, I don't think that anything is overheating heating on that card, it is just at the limit of what it can do.

But I did notice on my card(MSI 660 TI PE) that there are two large chips on the back. Are those memory chips? And if they are don't they need to be cooled? I poked one while my card was under full road and it burned my finger!

Yeah, I always wondered if adding some heat sinks all around would help with the stock cooler. But I could not find any small enough to fit under my stock cooler. I wonder if anyone ever added to the back?

I needed a new card, so I bought one!

Actually, I got an unusually large sum of birthday money, so I went ahead and blew it on a new video card. I haven't had an nvidia card in a while, so I figured what the hell... so I got a really nice GTX 660 Ti (since I can't afford a GTX 670 at the moment.)

So lately my my MSI gtx 660ti doesn't turn on my display after coming out of sleep mode. I swapped my old gtx 460 to test and it would turn my display on after sleep mode. Not sure how to fix this ....any ideas?

Well sometimes it works and sometimes it doesn't...I just unplug my hdmi cable and plug it in again and it turns on.

My 660Ti has been making a very high pitched sound while under load for the last month or so. Is this normal?

Not really a problem because I usually wear headphones, but still kinda annoying while I run benchmarks when overclocking.

Also what scores are you guys getting in 3D Mark 11. I just ran it and I got P9471. Is this a good score?

I am running my i7 2700K at 4.6 Ghz And my 660 Ti is overclocked +75 on the core and +600 on memory.
post #666 of 3662
It could be your PSU, or the card too, try connecting it with different cables? Maybe they ones that came with your PSU.
That's a great score.

I have the same motherboard, and have also had this issue. It's not your GPU that's the issue, it's your CPU overclocking that's causing it. Update your bios from Asrock.. Apparently, windows 7 and internal PPL Overvoltage "enabled" causes Sleep and Wake-up issues, you can look it up on Google. After i updated my MOBO BIOS, that problem went away..

Hope that solves the problem for you, if you want to find out if it's your CPU, then restore default BIOS settings, and run your system at stock, then try to sleep and wake up. Your system should wake up instantly smile.gif, then you know it's internal PPL overvoltage

that's a good find....
but first just check for disabled sleep if there is not much overclocking going on like you showed..

Thanks for your feedback! Yes...I have the latest bios 2.70 and I already had disabled the internal PLL Overvoltage in the bios because I had already read on the Asrock OC Guide that it would cause sleep and wake problems. Is there any way that the CPU PLL Voltage may be causing this? I believe I have it on auto.
