Hello,

So I have been tinkering with my new EVGA GTX 960 4GB Gaming. This is EVGA's newest 960. It is nothing special, just a reference / blower fan card. It is much nicer than my previous PNY XLR8 960 which had a bone stock Nvidia branded PCB. Compared to the PNY, the EVGA has a thicker custom PCB, better capacitors, 8 x 512mb Samsung chips, copper heatsink, and decent branding. This is the best 960 for my case in my opinion, which ideally should be paired with a reference designed video card.

Anyways, I am looking for some input on overclocking. I am somewhat newer to overclocking in general, and my current build is my first using an Intel K Series CPU and Nvidia GPU (I come from a long line of gaming laptops) I was originally more focused on getting my i5 4690K dialed in. I ended up settling for 4.5ghz @1.2v with that due to the cooling capacity of my build. (ITX Case, Lower Profile Heatsink)

Right now I am using EVGA Precision X. It doesn't seem quite as user friendly as MSI Afterburner, but having an EVGA card I figured it would be ideal to roll with matching software.

I have my power target at 105%, GPU Clock +173mhz, Memory Clock +400mhz.
So my card currently runs at Core 1300mhz, Boost 1351mhz, Memory 7800mhz. However, while in Unigine Heaven GPU Clock is showing 1450mhz.

I would like to get a little more out of this card. I see where people are running Core 1500mhz + and Memory 8000mhz+. I understand that my card doesn't quite have the cooling capacity that others with larger heatsinks, dual / triple fans, back plates, etc do. I am also well aware that not all silicone is equal. I have been trying to pull Core 1500mhz and Memory 8000mhz. I get artifacting / driver crashes when going this high with either of them, simultaneously or not. +400mhz on my VRAM seems to be my cap. The memory chips on my card do not have any type of heatsink on them. I am not sure if this is the issue or not but even with my current overclock my temps are fine.

The main thing I am wondering about is power / voltages. I am assuming if I wan't to push my card further, I am going to have to give it some more power. I have never messed with voltage. My 4690K was my first CPU that I manually adjusted voltages for. I have everything figured out on the CPU side, now I am just wanting to learn to tweak the GPU.

Here is a pic of my card:


Two things: What is the stock maximum voltage value, and what is the ASIC rating of the card?

I got an ITX EVGA GTX 960 (single fan, single 6-pin), arguably with the worst cooling of all GTX 960 cards. I also hit the 80C mark when I run at 100% GPU load for extended period of time.

However, I can easily overclock +132Mhz (max boost of 1549MHz) and +200Mhz to the memory. I possibly can go further, but didn't bother.

I'm told that "GPU lottery" eventually decides how far you can OC. Some cards can even OC to 1650MHz at stock voltage settings. My GPU has a 83% ASIC rating and runs at 1206mV out of the box.

I'm running an MSI 2gb (100 million edition) at 1590mhz core and 4000mhz memory. BIOS tweaked for 1.275v and 180w TDP(single 8-pin connector). Thermals are good on this card with a 93% ASIC quality score.

How many volts are you drawing under load and what are your temps like on that reference cooler? Does it have a single 6-pin power connector?

Can you share with me what was your stock voltage rating?

I am thinking of undervolting by 100mV to get cooler temps (which at the same time higher clocks). For example, at stock 1106mV I got 1354MHz, but after a +110MHz overclock, at 1106mV I can get 1455MHz.

This card just has the standard 6-pin power connector. My temps with my current overclock are: Idle 28c / Gaming 55c (+/- 5) / Stress Test 78c. I have never seen it go past 78c during Furmark, Unigine Heaven, etc. I replaced the stock paste with AS5 as well. My previous PNY XLR8 960 that I also replaced the stock paste on ran 6c - 8c hotter. I assume this is more so due to the even crappier aluminum heatsink. At least EVGA opted for a nicely finished slab of copper...

As for voltage usage I will have to do some testing / monitoring. I could also improve my temps as well. I noticed that even under 100% load the card is quiet and only pushes the fan to around 60% - 70%. Much quieter than the PNY.

EDIT: How do you find your ASIC quality?

I ran a quick test, monitoring stats while running Furmark and Unigine Heaven.

Stock:
100% Load / 90% TDP / 1.1680v

OC:
100% Load / 93% TDP / 1.1930v (1.1680v most of the time though)

Idle voltage is 0.8560v.

Install GPUZ. Click on the top left corner, you will find the option to determine your ASIC quality.

Maximum voltage STOCK was 1.243v I think. AGain, this is an 8-pin power connector card with 2 fans and a non-reference PCB

Just got into overclocking this past week. I recently bought a EVGA GTX 960 SSC 2 GB, I was in the past previously with my Radeon HD 6850. Anyway I have been tuning my overclock to work stable with the game Overwatch. I was able to reach 1478 MHz Boost Clock and 3564 MHz Memory Clock. These are my RESULTS

Not bad so far.  The SCC is voltage capped at 1.275 which should be more than enough to get 1520+, but the stock bios limits it to 1.206 IIRC.  I currently run mine at 1545/8000 via modded bios.  The one major downside to running a modded bios though is that the stock rom refuses to flash.  I keep getting a bios error every time I try, but I can always reset the values back to stock in the modded version. My only concern is the checksum that may disclose to EVGA that my bios was modded and void the warranty.  Anyway, welcome to the club and enjoy your 960. :thumb:

Is it "good" to hit 1541MHz stable (boost 2.0 value) on a GTX 960 SC 4GB (short ITX version) with 6-pin power and without raising voltage above the stock values?
post #769 of 865
1541mhz without OC'ing? What is your ASIC quality score?

The posts above me were talking about overclocking, so yes it is with an OC. Obviously!!!

I didn't raise voltage values though and power limits are same. ASIC is 83%. GPUZ says better than 97.5% of GTX 960 cards, but I don't believe it.

Out of box the boost is at 1418MHz, which is still pretty decent I'd say.
