At today's price ($10 per ETH) and difficulty a 380 will earn around $90 a month, after power costs. But the difficulty level has doubled in the last month and seems set to keep rising rapidly, so I'm not sure you'd ever recoup the cost of the card.
I bought my last mining card about three...
I've used six Nanos to date (two of which are mine) and they all have coil whine, but it's quite minor and the only reason it's audible at all is because the Nanos are so quiet. I've heard far, far worse on a wide variety of other cards. Really it's a non-issue.
In fact so far my one and...
So much this. I'm surprised the Nano doesn't get more love for its great value. The price cut has made the Fury (and the 980 for that matter) look significantly overpriced.
Process improvements can throw up performance jumps like that. Remember the RV770, aka Radeon 4870? A 260mm2 chip that arrived and delivered performance equal to, and sometimes better than, NVidia's competing 570mm2 GT200.
Not sure about the 210s, but the Radeon 6450s will run dual monitors no problem. And four monitors from two 6450s will work just fine. The thing is to always try and make sure all cards in the system are of the same family, to minimise driver issues. Two or three 6450s will work together, but a...
The 2GB/256-bit Tahiti came out under the name 7870LE. It was fairly quick and could have been a good card but all the ones I saw were 1000MHz core @ 1.25v and ran very hot. It was plainly just a dumping ground for low-grade salvaged Tahitis that couldn't be used anywhere else.
There have been quality control issues affecting a couple of batches of the BL3200PT (and other monitors based on the same panel) which understandably makes people unhappy, doubly so with such an expensive monitor.
But I've seen little other than positive reactions from the vast majority who...
I don't find ghosting to be a problem. It's there and you can see it if you look closely, but it's no more of an issue than with most VA or IPS screens. The Premium AMA (overdrive) setting is pretty good at reducing blur, at the expense of introducing some overshoot.
There's not much I don't...
I've used several 27" 1440p IPS monitors and personally I haven't found one that even comes close to the BL3200PT.
I did worry a little about pixel pitch on the BenQ, but in practice I've found 1440p more comfortable at 32" than 27". And the sheer size coupled with the AMVA panel's excellent...
If we define GPU as a programmable graphics system, then my first was the ECS chipset in the Amiga 500.
My first VGA card with any kind of 3D function was a 2MB Matrox Millennium PCI card, which had very basic 3D (it couldn't do texturing, if I recall). That was replaced by a 4MB Permedia 2...
I have a pair of 290s that I use for coin mining and touching the vents or the black metal part of the cooler is very painful and I'd say quite likely to inflict a minor burn if touched for more than a couple of seconds. The air coming out the back is hot enough that it's uncomfortable to hold...
The DS has really good quality for such a cheap card. As a card for music it's a complete steal, but the drivers don't support Dolby Headphone so it's not the best choice if you want multi-channel audio in games.
There's a bit of overhead involved, so SATA-I can't actually exceed about 135MB/sec in practice. But there's no need to worry about it, only the SSD's sequential read speed is bottlenecked by SATA-I and that's not going to slow the drive's overall performance very much.
With the 02HA firmware and standard Microsoft Win 7 AHCI driver Crystal Disk Info is saying no TRIM support on my 40GB Kingston, so I guess we're out of luck on this one.
NVidia may find a temporary withdrawal turns into a permanent one very quickly. Security of supply is a big deal in the industry, you can't just say "sorry guys, no more cards, maybe next year, eh?". Board partners and OEM customers will go nuts. Remember when AMD sold most of their production...
What GF are saying makes perfect sense, bearing in mind that 32nm SOI is only going to be used by AMD. If AMD have had to delay Bulldozer then the timeframe for initial production of 32nm chips slips even if the process is 100% ready on time, purely because there's nothing to build. 'not because...
Worst
Creative Labs Graphics Blaster Exxtreme PCI
Absolutely the worst graphics card I've ever known. Whoever decided using the Permedia 2 chip on a consumer 3D card was a good idea needed shooting. Every game I ever tried ran like cold treacle no matter how low the detail settings. Quake 3...
In my experience, no, any change of the PhII's clock multiplier disables CnQ. Not sure if that's a general rule or a quirk of the Gigabyte motherboard I'm using.
A word of warning about Gigabyte's MA790X-DS4 and Phenom II support. Some of Gigabyte's CPU support lists (like the one linked below) show BIOS F5 as being required for PhII support, but that's incorrect. BIOS F6 is actually needed, the two 790X-DS4s I've tried will not even POST with F5 and a...

"On the Intel platforms, we used DDR3-1333 with timings set to CL 7.0-7-7-21"
AT doesn't specifically say what memory was used on each platform, but it lists the socket 775 board they used as the Intel DX48BT2, which is a DDR3...
Both the AT and Tom's reviews used DDR3 on the Intel systems. Show me an Intel /DDR2 setup that beats the PhII-940/DDR2 at the same price. From all the reviews I've seen there's no such thing.
I'd love to see reviewers do a cost-for-cost system performance comparison rather than a clock-for-clock one. Say a Q9650 with 8GB of DDR3-1333 and a 7200rpm HD vs a PhII-940 with 8GB of DDR2-800 and a 60GB SSD, which should be roughly the same cost if my sums are correct.
Yeah, several sites are pulling that trick. Just finished reading Extreme Tech's rather poor review and they do it too. DDR3-1800 for the benchmarks and DDR2 for the price comparo.
I can't decide if this is incompetence or dishonesty. It's hard to believe there are so many bad hardware...
That may be quite an important point. Most reviewers are using DDR3 for the Core 2s (including AT, if I'm reading the test setup page right) which is hardly fair given the price differential between DDR2 and DDR3.
Hexus used DDR2 for both systems, which could be why their numbers show the...
HardOCP always seems to dismiss anything except the very top performing hardware as a waste of time. I get the feeling Kyle thinks everyone should be running i7-965s with 3 GTX 280s in triple-SLI and doesn't quite grasp why people are mostly interested in something less extreme.
My 500GB 7200.11 is pretty loud. Not first-gen 7200 ball bearing screamer loud, but enough that it's annoying in a quiet PC. Much louder (particularly when seeking) than a 6400AAKS and not even on the same planet as a 6400AACS.
I won't be throwing it away, but I won't buy any more of them.
I just bought both a 6400AACS (GP) and a 6400AAKS (SE16) this week along with some other drives and I've been doing subjective tests by imaging a really cruddy Vista install on to them and playing about with it. Both WD drives feel very quick, the SE16 being the snappier of the two but not by as...
The Phenoms are a better choice if you're building a system with integrated graphics because their faster HyperTransport links give the IGP more memory bandwidth. I recall the 780G chipset benchmarking about 50% quicker with a Phenom than a K8-based Athlon X2.
The red LEDs go when the card isn't getting enough power, so your PSU is probably having a hard time coping with the 4850's startup current draw. Time for a new PSU.
Some kind of issue between the driver and your software, for sure. HD acceleration works just fine for unprotected files on my system (4870/hotfix driver) under PowerDVD and DVBViewer.
