Hey GTX 660Ti owners,

We are having our monthly Foldathon from Monday 19th - 21st 12noon EST.
Would you consider putting all that power to a good cause for those 2 days? If so, come sign up and fold with us - see attached link.

December Foldathon



To get started:

1.Get a passkey (allows for speed bonus) - need a valid email address
http://fah-web.stanford.edu/cgi-bin/getpasskey.py


2.Download the folding program:
http://folding.stanford.edu/


Enter your folding name (mine is the same as my OCN name)
Enter your passkey
Enter Team OCN number - 37726

I have had a MSI 660ti PE 2gb for ~4y on the wife's computer, and it's starting to show it's age on the newer games, so i took it apart for it's 1st thorough clean and re-TIM and temps dropped by around ~20c. All this time it has been at stock, so 1097mhz-1241mhz/6008mhz so i took the opportunity to OC it a little, ended up with +0v 114% +65 +600 (voltage, power limit, core, mem respectively), so it boosts to 1306mhz/7204mhz on stock voltage 1.175v (ASIC is 86.6% if anyone is wondering) at 72c with Heaven on loop 2h 1080p max settings. This is with zero throttling and i'm positive that it can go further if i pump the voltage because neither core or mem threw up artifacts yet. I have had an Arctic Accelero Hybrid III-140 lying around for months that i never got to use that i wanted to install if possible which will further help with temps.

Question time: i ran out of room TDP wise. If you refer to the 1st screenshot - modding the BIOS will only raise the total GPU power, the "normalized" will work as if nothing was changed, anything extra on the voltage or clocks or a very GPU intensive game will hit 98%+ and it starts to throttle. Is there a way around this or a hardmod for this card ?

Full Specs:

CPU: FX-8370, 4.5ghz 1.368v
Cooler: Hyper 212 EVO - SP120 LED 120mm x2
GPU: MSI 660 Ti - N660Ti PE 2GD5/OC
RAM: 2x 8GB Corsair Vengeance Pro 1866mhz 9-10-9-27
Motherboard: Sabertooth 990FX R2.0
SSD: Crucial M4-CT064M4SSD2 64gb
HDD: WD10EZEX 7200rpm 1TB
PSU: Corsair TX750
CASE: NZXT S340 - AF140-LED x3 - AF120-LED x1
OS: Windows 8.1 Pro 64bit

I'm in the process of overclocking my ASUS GTX 660 Ti DirectCU II using MSi Afterburner and just wondering if the the "Core Voltage (mV)" can be cranked all the way up or is it better to OC with no voltage increase with this GPU.

Also while testing yesterday I found that adding anything more than +60 to the "Core Clock (MHz)" caused crashes when testing. I've read that this model is already clocked high and you may only be able to go go further with the "Memory Clock (MHz), so just wondering if this is the case.

Computer Specs: i7-4790K, GA-Z87X-UD5H, G.SKILL Ripjaws X Series 16GB (2 x 8GB) DDR3 2133, Gigabyte GTX 970 Windforce OC, Corsair TX850M 850 Watt Gold, Noctua NH-D14, Phantom NZXT 410, Dell P2414HB Monitor, Klipsch ProMedia 2.1 Speakers, Ducky Shine DK9008 Keyboard, Zowie Gear FK2 Mouse, PowerDeWise Lapel Microphone.

You have to increase the mV when you start to hit the Core limits, but keep temps low.

Ok, I'll give it a try, I've seen a few posts with this card and folks didn't go over +50 on the mV. I reapplied the thermal paste and that's not what has been holding me back, it never reaches 70c during testing.

I'm having trouble unlocking the voltage on a GTX 660 Ti, It only wants to top out at 1.17v regardless of what I change in KPE / Bios
