Now got GPUz3.1 and it's showing the same info.

Image

So at least my system is running PCIe V 1.0 x16 @ x8.

The only thing I can suggest why Greg's is showing one at V1.0 and one at V2.0 could well be due to his having two graphics cards. I think it would need more people to post on this though.

(sorry for double-post)

Ok after reading a bit, here is the conclusion to the Pci Express.

A card like a 8800 GT / 9800 GT as a bandwidth of about 60 GB/S

A card like a GTX 280 as a bandwidth of 140 GB/s.

Those numbers are theorical and tests showed that GTX 280 peaks at about 115 GB/S.

A PCI Express 2.0 x16 has maximum bandwidth of 160 GB/S. PCI Express x16 has 80 GB/S. So PCI Express 2.0 x8 has 80 GB/S. Which is logical. Imagine it being a PCIe 1.0 x8. It would have a 40 GB/s maximum bandwidth and would SERIOUSLY bottleneck even a 8800 GT / 9800 GT.

So we can conclude two things. First, xps 630i has 2x PCIe 2.0 x8 lanes, since the 8800 GT's are not bottlenecked at all when you compare benchmark with other Motherboards having 2x PCIe 2.0 x16. Secondly, a 8800 GT is about the limit of this bus line and anything higher than that or a 4850 (65 GB/S) would be bottlenecked by the PCI express lanes on the 630i.

A link explaning the lanes :

http://www.tmworld.com/article/CA6419189.html

For the bandwidth of specific GFX cards, just do a quick google search (ie: 8800gt bandwidth). It's discussed on many forums.

Nice work!

Actually supports what I've been bumping my gums about from day one. The 650i board was not the best choice for the customer. Whether our board turns out to be PCIe v1.0 or 2.0 is to some extent by-the-by, if any customer wants to upgrade the GPU to a modern one they would have to considder a mobo upgrade as well, and when you considder the licenseing regs with OEM it would also mean a new OS purchase.

Yup, and i know i want new GFX when the next generation comes out (whether it's GT300 or something like that), so i'm going to upgrade my motherboard soon.

Excellent notes, both of you--added to the x16 slots/8-lane commentary of the Issues page.

That is an odd review, their main criticism is that there is only 1 120mm intake fan when you can see from the picture (and as we well know) there are 2!

I am interested in that AlienFX editor they show a picture of here: http://hothardware.com/Articles/Dell-XPS-625-Phenom-II-Gaming-System/?page=5.

Anyone know if/where we can download that for 630?

It also states that the GPU runs at x8 by default even with only one card. Wonder if there will be a Phenom II PCIe x16 @ x8 debate going on. :roll:

But it does seem to be at PCI-E 2.0 though... which is a pretty important difference

Very true, and it should prevent the urge to upgrade the mobo for a little longer than our board is able to do. Would be nice to see a couple of benchmarks from owners as opposed to websites, they allways seem to differ in my experience.

Received my xps 625 last week after a short delay. Seems built solid. The fusion is real convenient for gaming. I ordered it with the dual 4870 1gb cards in crossfire. The video card slots on the motherboard are very tight so there is just a small space between them.

When i received the computer, i noticed it wasnt recognizing the 2nd card. I checked device manager and CCC. Both had just 1 card. After speaking with a Dell tech and him checking my pc, we tried switching around the cards. Just the top one was recognized, so it wasnt a bad card. He gave me 2 options: return the pc since its under 21 days for a new one or have someone come and replace the motherboard. I chose motherboard replacement (this was yesterday so it hasnt happened yet). I cant believe that they didnt make sure both cards were running before it left the factory.

Other than this issue, it seems like a good pc. I added a Striker 7.1 soundcard, 8 gb of OCZ Fatality ram, an Artic Cooling Freezer 64 pro cpu cooler (which fits nicely but only if your rams heatsinks aren't tall), 92mm rear fan. I got it with the blueray burner combo drive so i added a dvd burner multi drive myself.

Dell tech arrived today and replaced the motherboard. Everything works fine now. I have both cards in crossfire (both show up in device manager now and i have the crossfire option in CCC). Not sure why Dell would send the pc out with a motherboard where only the one pci express slot was working.

I mentioned it before but i really like the Fusion software. Lets me shut down with one click all the unnecessary stuff (or make a profile of what i want to shut down) when im gaming or whatever. Pretty cool feature.

Glad you got it taken care of so easily. I have a 625 on order that is coming with one HD4870 1024. Now I'm worried that my second PCIe slot may not work and I won't know it until later when I go to upgrade... Hopefully it was just an isolated incident.

Glad to hear you like the AMD software. I'm looking forward to it.

Are you overclocking the processor?

I've started up the Overdrive software a couple times but haven't tried changing anything. I really don't know alot about the settings and stuff. Guess i'll have to read up on how it works. It looks cool though.

I was relieved that changing out the motherboard fixed my issue. After reading alot on here, i honestly thought it was an issue with the catalyst driver. I installed and removed both the Dell provided one and the past few versions off the ATI site but none of that fixed it.

I would check the motherboard out real good once you receive your 625. Put the card in both slots to see if its recognized in device manager, etc. Your under the 21 day coverage so its best go at it early on.

One thing i noticed about he video cards on these is that they are mounted/built into large tray like things that fit into slots toward the front of the case. Looks like these are for added support. Also on this motherboard, it you are running 2 video cards it will leave you with 1 PCI slot and 1 PCI-E slot available for upgrading (I use the PCI for the sound card). The 2nd PCI slot is covered by the 2nd video card. The video cards are pretty tight in there, probably 1/2 of an inch max between them (dual slot ones). After adding the rear fan (a must and easy to do) and changing the cpu cooler (the stock one looks very nice though also), heat doesn't seem to be an issue at all.

What size/brand fan did you add to the rear? Also, is it controllable or can you at least monitor it with the XPS software? Thanks.

I purchased the 92mm AeroCool SilverLightning white case fan. It is quiet and has white led's built in. Comes with the screws and the holes to put it in are already in the bottom grill of your computer. There is a plug for the fan perfectly placed on the board for the rear fx lighting right beside where the fan will be. Takes like 3 minutes to install. Its $8 on Newegg.com. Also has good reviews. This fan is really good but you have to not mind the additional light in your case, its pretty bright with 4 white leds.

I haven't checked to see if this one is controllable so i'm not sure. Its a really quiet fan and in combination with the Artic Cooling cpu cooler with its fan, the 2 large stock front fans, a small fan on motherboard, and the 2 video card fans, their is alot of air being pushed out.

Here is the interior of the xps 625 with the changes ive made. New cpu fan, added rear fan, upgraded ram, put in 2 more hard drives, and added Striker 7.1 soundcard. I need to tie up the cables up top but still messing with it so havent had a chance to. The video cards fit pretty tight as you can see.

I decided to try out another motherboard on the XPS 625. Here are images where i installed an Asus M4A79 Deluxe. I reinsalled windows from the original disc with so far, no major problems. I saved the original windows content to a windows.old file. I'm still working on the settings but so far the switch hasn't been too bad. The biggest issue was the power on/off button in the front of the Dell case. I was able to find the power and ground wires on the plug and by turning the plug to one side get it on the motherboard jumper. However, i do not have the hard drive light or the power button light on anymore. The FX led's remain lit (continously white) but i havent tried to reinstall the FX software to see if i could get it working again.

There is alot more room between the video cards when compared to the stock mb in my earlier post. The Asus board has 4 pci-express x16 slots (with these cards, 1 of the 4 will be covered and not usable). I kind of rushed through the hardware part so ive got alot of cable rerouting to do.

Looks like the Alienware rigs are a better deal.

The entry price of the Area 51 750i starts at $899. I don't think their motherboard they use is crippled like the 630 is..
