MSI GTX 660 testing

MSI GTX 660 testing

*so far I was testing the card with a review driver since Nvidia just released 306.23 today, which is meant to include the 660. The driver I was using seemed to have issues in older versions of DirectX ( 9 and below - as well as some shakiness in 10 ), For this reason I am retesting with the version that released today and will be updating this as I go along.*

For the current post I will post some pictures while I get some results re-ran instead of posting up pre-release driver tests.

The unit I have is an OC variant, with Afterburner I am able to get the card to its max for Unigine Heaven (DX11) and 3DMark11 @ a base/boost clock of 1118/1183 (MHz) and a memory clock to 1757MHz - this is over the stock 1033/1098 core and 1502 on mem. During the benchmarks that I was able to run with the pre-release driver I found it was happy chugging along at 1200MHz (a few ticks under1200 up to 1228 depending on the part of the scene)

Memory Size: 2GB GDDR5
Memory Bus: 192 bits
Outputs: DisplayPort / HDMI / DL-DVI-I / DL-DVI-D

Card Dimension: 235x125.2x35.8 mm
Form Factor: ATX
DirectX: 11
OpenGL: 4.2
PCI Express: 3.0
CUDA: Yes
SLI: Yes ~ 2-way
PhysX: Yes
PureVideo HD: Yes
3DVision Surround: Yes, 3 outputs per card






To be updated soon - will be a as soon as I can do it (Very Tired with a long night of testing done and more to do asap )























Test Results

I will be running many more tests - these are just the beginning - It does take a while to run each test a few times and do a lot of them for fine tuning card settings, edit them, make the posting easy to look at, and get rested for it again lol.

Moar tests on the way

Card looks like a worthy GTX460 replacement. Still don't like that 192bit bus though, it just feels... wrong.

[CrazyNutz]

Interesting! So this is the 660 non-ti with the gk106 rather than a gk104. Waiting to see how it performs.

Hardwarecanucks has already done a review, OC'd without any voltage adjustments the 660 can hit stock Ti performance which is pretty good. Once you throw in some voltage I bet the 660 is a monster in disguise!

[TheGoat Eater]

I have an afterburner version able to do so... check the version if you want to play wheres waldo lol. with it I was able to do no better than without any control at all - definitely seems a great value - been playing Diablo with it and going to test it on others later today after some sleep.

I did update the above thread with tests and there will be more over the next few days - also - any requests?

[reb0rn]

I bought the same card, my OC limit at default voltage is GPU: 1089 boost 1154 and memory: 1677

Can you pls share MSI afterbutner with voltage control ?

[TheGoat Eater]

I cannot share my afterburner with anyone - it is specific to me and I don't distribute NDA materials / Its "MSI Afterburner v2.2.3 Ryan" I can say that I am not sure if the slider is actually functional as I am not getting better clocks. I will be making a new testing OS today that will hopefully resolve some issues I am having with my driver (doubt it but I have my fingers crossed).

for the sake of time I am going to try a more conservative OC for all benches instead of tuning for all - its killing me (ugh)

[CrazyNutz]

Goat, Can you post the bios please? I have developed a kepler bios unlocker tool, I would like to take a look at this bios so I can add support. Thanks

[reb0rn]

I tried extracting bios with gpu-z and Nibitor and both are no go for MSI GTX660

Also i read somewhere that voltage control chip on MSI does not support software adjustment

You have to use this version of GPU-Z: http://www.techpowerup.com/forums/sh....php?p=2695913
