Hello,
Although Number Nine and all rewievs have written Savaga4 as graphics chip of the SR9 NLX but without heatsink I have seen Savage4 LT only like this:

I think all of the SR9 NLX are Savage4 LT with headsink.
But might be there is two type:
1. Savage4 with headsink;
2. Savage4 LR without headsink.
It would be great to check it.
