The 660 Ti Thread: Questions and Answers Here!

[Banacek]

Hello! So I just finished installing my SSD and upgrading to 10.8.2 on my Hackintosh. Everything is working great. Now I'm about to upgrade my video card. Here are the details:

Old Card: ATI 5770
New Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125441
Motherboard: GA-P55-USB3 http://www.gigabyte.com/products/product-page.aspx?pid=3440#ov

So, anything special I have to do to swap the cards, besides set GraphicsEnabler=No?

Thanks!

To answer my own question: yes!

Card works great, no issues so far.

It's not just Linux and OS X that sleep doesn't work with my 660 ti apparently. I just had it crash in Windows 7 too... right after waking from sleep. Looks like it might be a problem with the card itself or a bug in its bios.

I can tell you from my own experience that the behaviour of your card is abnormal; I can sleep/wake just fine in 10.8.2 and Windows 7/8. If you are skilled enough, extract your bios in Windows using GPU-Z and save it in a safe place. Then head over to Techpowerup (or use Google) and do a search for your BIOS and try flashing your card. If that fails (or does not resolve your sleep problem), I suggest exchanging/RMA your card ASAP.

Note: I have noticed some odd readings in HW Monotor. Running a GPU benchmark, the GPU clock reads in the 1115MHz range, Memory Clock reads aprx 6000MHz which is correct, but the ROP/Shader clock pushes past 2000MHz (double whatever the GPU is)!!! To my knowledge, the ROP/Shader clock is the same as the GPU. Is this a misreading by HW Monitor?

No, I think my card's fine. I found out that the blue screens in Windows only occur as a result of unstable overclocks on the core speed. This has me wondering if a misreading of the core clock of the card has something to do the instability of waking from sleep in Mountain Lion too; when I run Luxmark in OS X, my gpu clock displays as 0MHz, however this could be just due to the fact that the 660 ti was never officially supported under Mountain Lion.

And about the GPU clock misreadings, I wouldn't pay attention to what HWmonitor says. I find EVGA Precision or MSI Afterburner to display the most accurate clock speeds. Trust me, I'm pretty sure your core clock isn't passing 2000MHz; I find my card to be unstable past 1260MHz on the core and 7200MHz on the Memory.

Hi guys,

I absolutely love this thread and thank you to everyone who's posted and helped.

I have read through every page and have decided on going with the Galaxy 660ti (due to building a silent system.. or close enough to)

Between the 2gb and 3gb Galaxy versions, I already saw that open CL is easily fixed using Netkas Hex edit (as on page 37 and thank you to that poster ). Also, I have not seen any real issues after this edit regarding system stability or sleep/wake issues, but would the 3gb be more inclined due to having to edit for additional memory? (I didn't see any, maybe I missed some).

My real questions is how much performance difference will there be between these two models in OSX? I know most will ask what are you using the system for, but really my concern is will OSX really utilize the additional resources between these two cards? Of course, PC OS for Gaming, but for OSX it's video editing, encoding, audio recording, and light 3D design and very light rendering, and most importantly system stability (current 6870 user on old system and love the uptime).

At the end of the day, is the price difference between these cards worth it and will stability be a large factor using the 3GB?

Thank you very much for any insight and taking the time to help.

Sincerely.

The only real benefit from the extra 1GB of VRAM would be if you were to run multiple monitors. As for stability, there should be no difference between the 2, with the exception of the OpenCl patch; If OS X sees so much as 1 extra byte of VRAM, it thumbs it's nose at it. As stated OS X doesn't technically support the 660 series, so one would assume that most will behave the same, regardless of the make, OC/SC, or VRAM size. From experience, OS X throttles up my 660 GTX Ti SC exactly as it would in Windows (1150MHz+).

Does the 660 ti boot full screen through the apple1 boot logo?

I've just put one the MSI 660ti card in my Hackintosh Pro. On a dell 24" @ 1920x1080 the Apple logo screen has a black border around the outside. Probably a couple of inches thick. So by default I'm guessing a no but I've not had any time to tinker!

Thanks, I been reading around I think it has to do with the monitor's native resolution both monitors that I have in my home are 1920x1080, I read that if its 1920x1200 it would fill in the black are. However when I use igpu intel 4000, I get full screen boot. I wish I can achieve the same with a discrete graphics.

Yep from what I could find in a quick search was that it's to do with a combo of the monitor and the GPU BIOS and how it handles VESA and the boot loader though please anyone do correct me if I'm wrong. I think the only way to get it to work is to try tweaking the bootloader and reflashing the VBIOS which from what I could find is a risky stratergy if you don't know what you're doing and for such a minor asthetic fix.!

I'm experiencing random freezes with my MSI 660 GTX Ti. I'm looking for a fix - I'm happy with the card but if it came down to it I'd probably buy a new card since this machine is exactly what I want from a computer.

Generally the log looks something like this before the freeze.
