I will (re)check the bios tonight (but I think I've already done that)
Also check your pci-e connector as Peter said. Each GPU should have a 6 pins connector at the back. They are necessary for the card to work properly. And these connnector should come from the PSU, not the twin molex to pci-e connector bundled with the card. These adaptors are for those who don't have enough pci-e connector on their PSU (read older).
At least one of the card work (I only brought one to work).
I put it in my colleague computer (I have a crappy dell with no slots) and boom it worked and booted properly (booted up to Win7)
At of today, lunch time:
- New System is fully working with old graphic card.
- New Graphic card is fully working (at least one of the 2) on different computer (ASUS Motherboard)
- New System is not working with the New graphic card.
Next step :
Check to see if I upgraded the Motherboard BIOS with all patches from the manufacturer.
I bought a GTX580, and it needed both the additional power plugs connected.
Also, i thought i had enough power with my 600W PSU, but found that the individual rails in the PSU did not supply the sufficient juice, and had to by a larger one. Although 600W was theoretically enough, the individual rail loads could not accommodate it.
so 2 things;
1) make sure you connect all the power plugs
2) make sure the PSU can supply sufficient current on the 12V rails that you are using.
While I was sleeping other members have provided some good information. The 'split rails' I mentioned is the converse case to Dan's (although the reasoning is the same). My split was load-side, not supply-side; that is, different sections of the card get their power from different connectors. Bear in mind that all connectors have a limited current capacity, and graphics cards draw a LOT of current, easily enough to overload a single connector. If you simply use multiple connectors in parallel, there's no guarantee that the current will be shared evenly, so you can still have a connector overloaded. (You often see multiple pins on the same connector paralleled. This works better because the pin-to-pin variations are less, so the sharing is likely to be more even.)
From your other post (3rd in this thread), it looks like you have addressed this issue anyway. It's probably only of academic interest now, but you could experiment in your one-card setup to see if my theory applies in this case. (Pull the 'top' power plug and see if it still works.)
Hope this makes sense - early morning, caffeine deficiency...
I have an old Linksys Wireless-G Router and A new Linksys Wireless-N Router. Is it possible to set up my old G router as an Access Point with the N router without having a Cat5 connected between the two(2). I would like to place the G router in a different room, without running any cables.
Hi, I plan to purchase iphone4. I heard that iphone4 could not send or receive bluetooth from the other phone (htc, nokia...). Is it true? If it is true, are there any possible way to make iphone4 could send bluetooth to any other phone legally (without a jail break)?
The former. The two generations newer i5-2400 stomps the 2 generations older E5800 silly. Anandtech bench comparison[^] The 8600 is the closest fit I could find and somewhat faster than the 5800 on account of having 3x the cache, and an extra 133mhz of clock speed.
I'm not sure what the 6350's specs are to make a comparison; but it's 2 major (4 total) generations newer than the 9300 and both have model numbers indicating that they're relatively low end parts.
Thanks Albert, it's my workstaion at work that's dying so I have to spec one that's reasonably priced. I saw the 390 with the i5 and it was essentially the same price as the 780 so wondered if there was something special about the Duo2.
When you say it's a RAM hog do you mean that it uses a lot of RAM for core functionality, or that it uses as much RAM as you can give it to work faster instead of just having spare RAM sitting there unused? (ie SuperFetch[^])
That's a good question... I think the answer is somewhere in the middle. Win7 does work a lot faster than XP for a lot of things (the boot time is a lot better too), but it uses a lot of memory just sitting there (thanks in part to the flashier user interface).
Now with that said, I wouldn't put WinXP on anything new, but in comparison, Linux can definitely run smoother on more modest configurations (and you have the option of using a flashy interface like Unity/Gnome3 or running on something simple yet fast like KDE/Gnome2).
Oh... and the reason I had mentioned the RAM to the OP is because I wouldn't buy a new desktop meant for Win7 with 4GB, I'd get at least 6GB. My personal desktop has 9GB, runs smooth. My laptop has 4GB but I run Ubuntu on that. My work computers, well... they're a diverse bunch .
Hello everyone! I am new to minifilter drivers and I have thought to design one that just appends a non-existent file to a specified folder, that is, let's say for the folder \test\, when I open this folder with explorer I would like to see its content plus a non-existent file (whatever it's name is).
I know that I should intercept IRP_MJ_DIRECTORY_CONTROL, and append the FILE_BOTH_DIR_INFORMATION structure corresponding to the file I want to "add", but I don't know how to do this . One easy solution would be to create a IRP response with the mentioned structure in the pre-operation and let the minifilter drivers bellow mine do the rest, but I am not sure this is possible nor how to do this. (Another possibility would be to append this information in the post-operation)

I dont know much about minifilter drivers for file system stuff, but:
When you register as a minifilter driver your IRP handler gets the Irps before the go down the chain. (There are numerous ways of doing this, async, sync, with or without completeion routines. Oneys book is good for the details on this). You want a synch with completion routine handling of the Irp.
So you handle the IRP_MJ_DIRECTORY_CONTROL Irp in your Device control func you registered at DriverEntry.
Now it gets into the unknown for me. I would imagine you allocate some new memry which is big enough for the original Irp buffer (can be in various places depending how the IOCTL is formed: METHOD_BUFFERED METHOD_NEITHER etc) and the additional data.
You then copy the old Irp data over, add the new data at the end. And point the Irp at this new buffer.
You send it down.
In your completion routine you point the Irp to the original buffer. Delete the one you allocated, and complete the Irp so it goes back to the originator.
Apart from the separate number pad, I would go for any of the Dell[^]range. I recently bought the XPS-15 and think it's a great machine (for me). If you're buying through the business then look at the Vostro range (and save the VAT).
That's less an issue that it used to be. One of the few arguable virtues of 16:9 screens is that became possible to squeeze a number pad into a 15" chassis; although it appears a lot of designs use the space to put speakers beside the keyboard instead.
