Hello everyone. First of all, thank you for this excellent thread. This 3L card seems to be a bit of an oddball, so the information here has been quite valuable prior to and after purchase. To pay it forward, I thought I'd register and share my observations:
1. Like others have noted in the 3L stripped thread
, one of the RAM chips on this thing, by the heat pipes, has a thermal pad but doesn't actually make contact with the heatsink. Given that I have been a longtime opponent on other boards of RAM sinks/pads or any other wonky useless RAM cooling tech, I took this omission as a sign and removed all of the pads from the RAM chips. Everything works great and now I'm contributing less heat (if there was any heat transfer to begin with) to the sink that's supposed to be cooling the core.
2. As previously noted in this thread, the VDroop on this card is pretty bad. My card is not the best overclocker, so to get to 1100, I use the 1.25V setting. That being said, I'm seeing it drop to 1.86V-1.2V in Crysis 3 so I'm not really feeding it anywhere near 1.25V to get to 1100. I keep the RAM at 1400 because 1500 was not stable and I am tired of fussing with it. Maybe I will try 1500 again since I've removed those insulators, er I mean thermal pads.
3. We do not have a VRM temp sensor, but taking a queue from this post
, I strapped a spare 80mm fan on the backside of the card over the area with the VRMs in an attempt to lower temps. It can't hurt and adds very little noise to my system, which is a wind tunnel anyway.
4. I'm running into a few quirks with the Board Power Li setting in Trixx. I usually put my system to sleep instead of shutting it down and I'm noticing that while Trixx will restore the previous profile on wake it is not really restoring Board Power Li to +20%, even though it still says +20% is selected. The end-result is if I do not reload my profile manually, my card will throttle in games and Unigen Heaven.
5. The "feature" in this card (all modern AMD cards from my research) where it runs at 500 core/3D Ram speed and hot with two monitors connected in order to prevent flickering is awful. I've actually looked into getting a fanless PCI card to run my second monitor but all potential cards have been cost prohibitive. This behavior is also making me wonder if having a second monitor is stressing the card, making it run hotter in 3D mode too, and limiting my overclock. I will experiment with this more at a later date. My main monitor is 20", 1600x900 and I'm not too excited about dropping dual monitor and going with a larger 1080p display instead. Less flexible than dual monitor and slower gaming performance to boot. No thanks.Edited by aldamon - 7/8/13 at 8:39am
