Thanks for the driver rundown! That'll save me the time and trouble of trying out the 256.53 driver.
----------------------------------------Consistent with what you wrote, I've had good luck running GPUGrid and MilkyWay on the new machine with the 260.19 driver, but PrimeGrid errored out. I read somewhere that you can get PrimeGrid to run with a carefully constructed app_info.xml file, but I think I'm going to just stick with MilkyWay on this machine. I'm running PrimeGrid on one of my HTPCs and GPUgrid on the other, both under the old 195.xx driver. I'll just leave those as is until those projects upgrade their apps and the 195.xx driver doesn't work anymore. Those are old single-precision cards, so they're going to be obsolete sometime soon in any case.  |

Intel was dumb - their high end processors shouldn't be the ones with the 3000 series GPU, high end processors end up getting discrete graphics anyway.... stupid! Tom's Hardware points this out very well. Intel is only dumb if you expect the high end gaming crowd to get these chips because of the graphics. I think Intel is going to push the graphics market to the middle and squeeze the discrete graphics card makers to the high end. Who wants a low or middle range card when it is built in ? Remember, AMD owns ATI. It is nice to be able to say you have the fastest, but the middle is where the money is. Intel is aiming for the high chip sales volume. If their pricing is aggressive enough, they will get it and AMD will stay on the defensive. The high-end gaming crowd will get the high-end SB chips because they are unlocked for overclocking, and are the fastest stuff on sale right now in the <$750 range, yet cost half that. High-end gamers will ALWAYS get discrete graphics, so Intel shouldn't have bothed with built-in on those chips. Your theory (pushing discrete to high-end) is sound, if it were what actually happened. The SB graphics barely keeps up with $50 discrete graphics, that is the lowest of the low end. $90-100 cards blow SB out of the water, that is still considered low-end. $120 and down is low end, $120-$240 is middle, $240 and up is high end. I agree, getting $50 graphics "for free" is nice, but only if that's all you need. The people buying the high-end SB don't want $50 graphics. Intel should have put the 3000-series graphics in all but the lowest price chips, rather than just in the high-end OC-friendly chips where it will never get used anyway. Stupid. As it is, most people will just get the 2000-series SB graphics, which is still slower than $50 discrete graphics.

Brink, did you try disabling 1 thread? I upped mine to 15 and still going good. Think it was a bad batch of WU's. Turned it back down as the difference in crunching time when almost maxes out was minimal. Will wait until prices start to drop and get a double precision card for my main rig and put this one in my ubuntu cruncher. Still haven't decided on which one yet but leaning toward the 470. What I did was upped the fan speed and reduced his 8 threads to 6. If I run the GPU fan at 65% his card stays at 51C. Have not had a blue screen on his system since I did this. My EVGA GTX 470 SC is running great. It can climb to 86C and stay stable. Rather than just guessing on stability of new hardware with BOINC stuff, turn all that off and run Prime95 for 24 hours and nothing else. Make sure you run it such that it uses up most of your free RAM too, to test all that as well. If that is good, then get FurMark to stress test your GPU. If you have problems, you may want to tweak memory timings and/or voltages. If FurMark dies, crank up the GPU fan a bit more. Also, with Windows Vista/7, a GPU freezing or locking up shouldn't give you a BSOD. Granted, I've only played with ATI, but when one of my cards locks up hard, the driver is smart and resets it. The system will appear hung for 30-seconds but then it comes back with an error message, but nothing dies. Even the game I'm playing doesn't die, it just ends up "paused" for a while! Point is, look elsewhere for your BSOD causes - prime95 is a good start, as is MemTest86.

So now I don't use his GPU to crunch just his CPU. BTW, did you mean to come off that condescending or am I just reading your post the wrong way? |

I've used a half dozen different ATI cards in the past 10 years and I've NEVER had a BSOD caused by one - the ATI VPU recover feature has always worked great when the card overheats or locks up. So despite your evidence, I would still urge you in a friendly manner to get to the bottom of those BSODs. Modern ATI cards can run up to 100C just fine, so if your temps are nowhere near those, I assure you it is NOT an overheating issue. It could very well be a POWER SUPPLY problem that is only triggered by heavy loads (like GPU crunching). You might be getting a voltage drop under heavy power draw loads that causes your RAM to start flipping bits. Etc etc...

I agree with you the high end crowd will go for the SB overclockable chips where the embedded graphics will be irrelevant for them. But do not underestimate the overall strategy of Intel. They are out to dominate any market they are in, maybe not right away, but eventually. Maybe the embedded graphics are more of a "proof of concept" iteration at this stage. Remember I am not a chip engineer, but merely speculating on some possible reasons for why they do what they do.  Cheers

Given the deal nvidia and intel just reached, and nvidia declaring to not build embedded graphics, got a suspicion a deal was made letting intel take care of the embedded market (for a price), and nvidia stay with dedicated graphics. What was it, 1.5 billion dollar bribe!

Despite Intel (INTC) agreeing last night to pay Nvidia (NVDA) $1.5 billion over five years to settle a patent dispute, it was Intel today that was up on the news, while Nvidia sold off. Nvidia shares closed down 32 cents, or 1.6%, at $20.31, while Intel closed up 36 cents, or 1.7%, at $21.05.
The deal is expected to boost Nvidia’s gross margin by 3 percentage points, boost cash, and add to earnings, and add 23 cents per share to EPS in the fiscal year ending in January of 2012, and 29 cents per year after that through 2016. http://blogs.barrons.com/techtraderdaily/2011...in-win-with-license-deal/ |

My guess is in about a year or so, we will find out the truth behind this deal.
