Thanks For The Input! What About The 280 In SLI? How Would The Computer Handle It With The Stock PSU?
I Am Kind Of New To This , What Kind Of Limitations Are You Talking About With The PCIE Lanes?
Thanks For The Help!
I don't believe that the stock 750W PSU will be able to handle the 280 in sli. I've heard that to run two of these you'll need at least 1K PSU, but can't know for sure since i don't have a pair of those. Now if you had a pair of 260s then you should be fine with the stock PSU.
The limitations are not that big of a deal yet. (Especially if game developers continue to water down PC games so that they'll run on consoles.) What the 630 currently has is 2 PCIe x16 slots that have only 8 lanes instead of 16. Which means that a single card solution, performance will be reduced because it has only 8 lanes to move data through instead of 16. But currently we are only starting to see GPU and software use up all of this bandwidth. Probably by the time the next wave of GPUs come out in the new year. The 8 lanes won't cut it anymore and you'll need to upgrade the motherboard. So with that said, the 280 is the start where we see this limitation in the bandwidth. Chris M from dell put together some benchmarks showing how SLI performs better than a single card in the 630 for various set ups including on with the 280. So that is why i say you should run things in SLI to get the most out of this machine until it is time to upgrade. By that time the i7 will be cheaper and the new intel architecture will be mainstream.
As you probably know allready the GTX280 requires one 6 pin and one 8 pin gpu power connector. The 630 is currently shipping with a single GTX280 which has a 6 to 8 ping adaptor pre-installed. The two gpu power plugs are also required to run the GTX260 but thats all you have, so you won't be able to install 2 GTX260/GTX280's simply because there are not enough power plugs. You could of course insatall a gpu only power suppy that fits into a spare CD/DVD bay, or infact upgrade the existing power supply to a 1K model as player8 suggested.
All the above though would be a little pointless, again as player8 quite rightly says, as the 8 lanes would hamper both 260 and 280 even in sli mode so you would be looking at a mobo upgrade as well. So cost of the graphics cards, mobo and PSU would make it possibly a better choice to simply buy a new system altogether.
These and many other issues with the XPS630i are being discussed over at www.my630i.com
In my opinion the upgrade limit without too many upgrades for a 630 would be a pair of gtx260s. This should require no other upgrade, maybe just a 6pin y splitter or some sort of adapter. And for performance wise i think this is about the best you are going to get. But with this upgrade though it should last well into mid 2010, i hope.
These cards are getting cheaper each month. Down to $219 for the 192SP version.
I appreciate the two replies so far. I am going to do a factory reset using the Dell Image. I did this once before, just after I got the machine as there was a conflict with the MacAfee and the ISP proprietary software I had installed.
I came up with the idea to use Windows Easy Transfer to transfer the couple of gigs of photos and videos I shot this summer as well as all the settings for the accounts I have set up. Is there any reason I should not do this? I checked all of the check boxes and there is no reference to the video drivers in there, so technically I should be able to have all my settings back and then reinstall the game giving me trouble and start over again.
Thanks for your help.
Well, I pretty much believe that this has all been covered. Especially in the old forums if not here. Dell was offering refunds to people who were not happy with the 16 vs 8 PCI-E lanes issue, but that is over with. Chris has said that there will be no Light FX software or motherboard replacements. As for the HD light, it doesn't bother me as I don't have the PC sitting right in front of my face.
Yep, those items have been covered to death.
Would have been nice though if Dell came out with a 750i mobo upgrade path for cheap.
Hmmm...well, it seems that the post that I replied to has disappeared. And yes, it would be nice for an upgrade.
Is it possible to install a new bios and then go back to an older one?
I want to install the 1.0.12 bios but in case it causes problems for me, i wanted to jump back to 1.08.
The reason being none of my OC settings are working. Even for a 100MHz boost. It can't be that my system is a lemon. (though i guess it is possible). I think it might be a conflict with some other software but still haven't pinpointed it to what. I figure that the 1.0.12 bios might help things.
