More Shift

OK, so I didn’t have the issues with my video card quite as under control as I thought I did.  RivaTuner established the overclocking profile, but at certain places in Starcraft 2′s cinematics I still got the black-screen reboots.  Every time.

So I got fed up and decided to replace the card.  Having been burned out a bit by ATI, I checked into the recent nVidia cards, but didn’t find one that hit the graphics horsepower levels I wanted with low power consumption at a decent price point.  Continuing to look around, I discovered the Radeon 5770 card, which very closely matches my old 4870 for pixel-pushing power, but is built on a 40 nm process so it runs at much lower power.  The price was great and reviews were positive, and the kicker was that the card only takes one PCI power cable, so I’m confident my PSU can handle the load.

There are several manufacturers of ATI-based graphics cards, so the next choice was which company to pick.  Sapphire was off the table from the get-go — I don’t know if the issues I had with the 4870 were power-related or card-related, but I wasn’t going to risk another round of video card instability if I could help it.  In the end, I decided to go with the MSI board, which cost about $20 more, but has uniformly high reviews for performance, form factor, low temperatures, and overclockability.

I ordered the card from Newegg and got it in Wednesday.  I didn’t install it until last night, partly to try to keep myself focused on writing.  But once I did, the install was simple and clean.  The old card came out and went back into its box, ready for one of my friends to buy it used, and the new card went in.  Drivers were uninstalled, swept, and reinstalled, and the card came up perfectly and ready to go.

Except that it makes no noise at all.  Even under load, this card is quiet, and at idle you’d never know it was there.  It idles at 37 C, which is absurdly low for a video card.  I guess I shouldn’t complain about it being quiet, but it really is spooky knowing that the card is cranking away and the fans are barely running.  I keep expecting the computer to catch fire.

So welcome to the component family, MSI 5770 Hawk.  May you have a happy, healthy, and long life.

Shift Happens

I’ve mentioned my video card struggles before.  It’s been a constant source of low-grade annoyance that I haven’t been able to use my card to its full capacity, but at least I found a way to allow myself to play.  Last night, though, even with underclocking I still had restarts just looking at the main menu screen in Starcraft 2.

Let’s not get off on the subject of why I was playing Starcraft 2 rather than working on my interactive fiction game — I’m saving that for a self-flagellating post later.  But once this problem started happening, I really wanted to figure out what the deal was, so I hit up Google and started browsing.

Some people had power issues, and that seemed plausible.  After all, it required some gyrations to get the card up and running in the first place.  Some people blamed heat, but when checking the card temps it just didn’t seem that high.  But then I found another article that finally got me looking in the right direction.

Apparently my model of video card has a feature where it automatically shifts the clock speed of the card between 500 MHz and 750 MHz depending on what you’re trying to do with it.  I don’t know all the details, but apparently 3D games under Windows 7 can confuse the card and get it to try to shift modes back and forth repeatedly, which causes the fan to go nuts and the card to eventually trigger a system shutdown.

The suggested fix for this was to lock the GPU to 750 MHz using an overclocking tool.  I downloaded RivaTune, followed the simple instructions for setting this up, and was rewarded with a card that runs stably (and quietly) at full rated clock speed.  Sure, it probably eats a bit more power just idling at the desktop, but it’s worth it to not have to worry about random reboots any more!

Slow Update Frequency

I’ll probably be dropping down to one post per week until the end of September.  There are a couple of different reasons for this, but the main one is that I’m trying to finish up my entry for IFComp 2010.  There’s a lot of work left to do, and I’m really needing to use as much of my time as possible on this to ensure it’s a top-quality entry this year.

Once that’s been released I’ll try to pick the pace back up again.

The Passing of a Good Friend

If there was one thing that defined him, it was his love for his food.  Or your food — the distinction was lost on Marco.  When he was young and we’d just brought him into our family after he grew too large to be a show dog any more, he’d scarf down his food so quickly you’d think he’d choke.  After he’d bolted his own meal, he’d horn in on his sister’s food, pushing his snout into her bowl and trying to shove her aside until she’d had enough of him and went medieval with snaps and growls and bared teeth.

Even when he started getting older he still had a hearty appetite — Thomas started an exercise program when Marco was 11 that consisted of holding out a piece of dog treat and running circles around the ground floor of our house, Marco scrambling along behind, always straining to reach the morsel.

Last night he wouldn’t eat his dinner, wouldn’t eat a spoon of chunky peanut butter, wouldn’t eat his favorite dog treats.

He loved playing with his sister and with people.  We used to play “soccer” — I’d kick a ball around and they’d attack it, with the odd nip at my heels thrown in for good measure.  They’re a herding breed, and when the two of them ganged up on me there was almost no way to get the ball past them.  It was very clear to me whenever I played with them what a wayward sheep on a Shetland Island moor must feel like.

When we’d play fetch, we’d throw a big rope bone out in the yard and the two dogs would sprint out to it.  Aurora was always faster and reliably got to the bone first, but Marco quickly learned that his size could compensate for his laziness, and would grab on to the bone when Aurora started to return and body-check his sister to wrest it away.

In that first year after we got him, when he was still very young, he’d nap in the sunlight on the carpet downstairs by the big glass door and his paws would twitch as he chased rabbits in his dreams.  He tried to be a good watchdog, but he was never as protective as Aurora — you never knew who might feed you, you know — and since his breeder was deaf and lived in a suburban neighborhood he’d been de-barked before we got him.  Not that it stopped him from trying, but he had a very soft, “Yarf”-sounding bark that would never have scared anyone away.

He’d had problems getting to his feet on slick flooring for a while, but something worse happened to him last night.  Around 10:00 he struggled to stand, and mostly couldn’t.  His head listed to the side and even when he could get some footing he staggered sideways.  He looked confused, and didn’t seem to be able to lay his head down flat.  He needed a pillow or a leg to rest his head on in order to get truly comfortable.

He was the gentlest of dogs.  There was never any concern about having our kids around him.  From Thomas to Katherine to Jonathan, baby to toddler to rambunctious, active child, Marco was always tolerant and affectionate.  Even in his waning days, Jonathan would come over and play with his ears (gently, or we’d remove him), and Marco seemed to enjoy it.  It was hard to tell for sure.  He hadn’t wagged his tail in months.

We knew he was getting sicker, knew his time was short and that we were going to need to make The Decision sooner rather than later.  Robin talked to Thomas about it when he really started having problems standing up on the hardwood floor a couple of months ago.  She explained that when he got so sick that he wasn’t enjoying life any more and was suffering, that we would talk to the vet.  If he agreed, we’d give Marco some medicine that would make him go to sleep peacefully and die without pain.  He understood.

But even though he understood, when the time came today he still cried, as we all did.  Goodbye, Marco.  Goodbye, old friend.  We love you.
