As of BOINC 7.x the way those settings works has changed. I believe it is now min cache and max cache and it won't connect as often. Does that sound correct zombie67? I know you have been using 7.x for quite a while.Quote:

On very few of the high-high-end motherboards (usually $350+) you may find a Lucid Hydra chip which adds a few additional PCIe lanes, but you're gonna pay through the nose for it.
The Big Bang Marshal from MSI has one. When all 8 PCIe x16 slots are filled, the bandwidth is this:
Slot Speed
1 ----8x
2 ----1x
3 ----8x
4 ----1x
5 ----8x
6 ----1x
7 ----8x
8 ----1x
If it wasn't for the Lucid Hydra, all of the x1's would be x0, which is how it is on nearly every motherboard, regardless of brand. Even though this motherboard is now obselete, MSI has yet to produce one that is more expensive, or even equal to the price of the Big Bang Marshal. Even the Big Bang XpowerII X79 board is cheaper. Nvidia's NV200 chip also adds additional lanes, but again, it'll never be found on cheaper motherboards. Every motherboard, regardless of how high-end it may be, loses at least 4 PCIe lanes to the functions mentioned above.
JPM, Thanks for the explanation. I wasn't trying to knock Gigabyte in particular, I have 2 and I find them very easy to setup and very well made. Thought it was by choice that they disabled the x1, guess I was wrong. That said, I guess you really need to check the specs before planning to use the x1 slots because you may find it disabled.
We got this put into my dad's atom which only has a PCI-e x1 slot and PCI slots. He previously had a PCI video card in there, but it went out. We got it installed, installed the drivers and then the issues started.
We can get the video to post to the PCI card, but then after it posts the video signal switches over to the onboard video, which would be fine if boinc recognized the PCI card but it does not. Looked for a spot in the bios to disable the onboard video but no luck. Any ideas?
I think one of the GPU gurus are going to have to help on this but, first off, I'd use the onboard video for the monitor.
Then, you have to tell BOINC to use the new PCI card through a special config. Xml thing --it automatically disables a lower card when there are more than one - so the pcie card is probably getting priority here. F$ and JPM and the guys can run circles around me when it comes to this stuff, but if you can go into the device manager in Windows and see that the 430 is installed and present, then it's just a matter if tricking out that config file in BOINC to make it work.
That would be JPM. I'll look for the post.Quote:

Persnally I'd use a Dremel tool with an Emery cut-off wheel. Easier cleanup and more control of the width of the cut.
I've had something similar happen before. Was a driver issue. Are there any other GPUs in the computer in any type of slot? If so, are they are all Nvidia or is at least 1 AMD? And if so, what OS you using?Quote:

Is it a Dell by chance? :p
Yeah, there must be a a few dozen terabytes of really good info over on the old boards ;(Quote:

I remember i got PCIe X1 cables and modded the cables to fit on a PCIe x16 GPU. Modding the slot wasn't an option on that board because a heatsink was in the way. And modding PCIe X1 cables is cheaper than buying a PCIe x1 to PCIe x16 cable.
And i agree. Use a Dremel. Very easy to precisely control, which is extra important when modding the slot on your mobo. And ummm... 8-> :-??
Just the onboard video and it is an intel gpu chipset. The onboard video card is not used for crunching. This machine previously had a PCI (not PCI-e) installed and it worked just fine until the card crapped out and my dad had to switch back to using onboard video to at least crunch on the cpu. We were not able to see any settings in the bios to disable onboard video. We did see one that stated something along the lines of what to use for initial video signal which we put to PCI. That is where the video signal starts and then after posting it goes blank. If you put the VGA plug to the onboard video then windows has started no problem.Quote:

There is definitely a conflict going on somewhere when it loads both.
Also, can you give me the model # of the motherboard? I'll find the manual and have a look at the BIOS stuff just in case I see something that sticks out to my memory...
Disabling the onboard in the device manager did the trick. Was a little newvous at first, when it didn't post to either adapter. The n I noticed machine was accessing network, so tried the new card again and there it was. Thanks DP! Thought I was going to be SOL on this one.:)
