Re: NEW XPS 730x Owner's thread March 15, 2010

My Core i7-980x should arrive via UPS today. Keep in mind, however, that unless you intend to use your PC as a workstation, the average user will not see any benefit in upgrading to the 980x. 

 

I will report back as to whether or not the 980x is compatible with the 730x BIOS.

 

 

P.S. - EVERYONE CROSS YOUR FINGERS AND HOPE THIS BABY WORKS WITH THE 730x!

Re: NEW XPS 730x Owner's thread March 15, 2010

Posted this in the main forum before I came across this thread. Figured I'd repost since this one seems to get a bit more 'action.' 🙂

==

Long time XPS owner (420), and about to pick up a 730x this weekend from a mate (price too good to pass up). Had a few questions for the experts on here who've been living with the system for some time.

 

My main goal is a tri-SLI rig, as his system has 2x GTX280s, and I have another I'd like to stick in. I am aware of the 16/16/8 lane configuration, and of diminishing returns on such a setup. I have run a similar system before with good success, so I know the limitations. However I am concerned about a couple things in respect to the 730x specifically:

- Does the PSU have sufficient power to run the 3rd Card? These are stock clocked 280s, so 1000W should be *loads* for this system, but you never know how OEMs actually spec their power ratings. (If anyone knows how the rails are spec'd, that would be fabulous).

- Does the PSU have extra PCIe connectors to hook up the 3rd card? I suspect Dell did not validate Tri-SLI on this system, and as such there aren't any more PCIe connectors on board. If anyone can tell me what connectors are available, that would be great (ie 4x 8/6pin or 2x 8 and 2x 6 pin, etc).

- Does the Dell motherboard have standard 1366 mounting holes? For obvious reasons, I'm planning on an HSF replacement.

 

In regards to power usage, I won't be running much internally - 2 SSDs, a single 1.5TB drive and a Blu-ray drive, plus the regular Dell complement of fans, card reader, bluetooth, etc. This is not the H2C system, so 1000W should be enough, but if anyone has specific knowledge or experience with this setup, that would be great.

 

Your help is much appreciated!

 

Cheers from Canada XP

Does the PSU have sufficient power to run the 3rd Card? Does the PSU have extra PCIe connectors to hook up the 3rd card?

1.) Yes, the PSU is sufficient to run 3-GTX280s in TRI-SLI.

2.) NO, there aren't enough connectors. The PSU only has 4 of the 6-pin PCI-E connectors and it takes 2 of the molex connectors to provide the same amount of power as ONE of the 8-pin PCI-E connectors. There are supplemental power supplies for doing what you have in mind, however, my suggestion is you stay with SLI because unless you have a DELL 3008WFP such as the one I use, you won't see any increase in performance other than when running a benchmark. In other words, TRI-SLI is usually done for bragging rights because the increase in performance is minimal at best. Your money would be better spent elsewhere.

 

Does the Dell motherboard have standard 1366 mounting holes?

Yes.

I run everything you see in my signature with no problems.

Re: NEW XPS 730x Owner's thread March 15, 2010

I'm also using a 3008WFP, so the extra rendering power is essentially mandatory...

 

4 of 6 is alright, provided the psu has the juice to run the 3 cards. I can adapt 2 molex to 6pin for the tertiary connectors to make it work.

 

If someone could quote me the amp rating on the 12v rail, that would be great. If Dell is specing these legitimately, it should mean 1000W/12v = 83A, which is pretty tight for an overclocked GTX280 setup. GTX285s draw significantly less power in SLI/tri than 280s, which have a much larger overhead, particularly in tri-SLI, where there is ~50w extra draw due to controller load.

 

3x GTX285s would draw roughly 550w (~46A) in such a setup, compared to GTX280s, which pull close to 710w (~59A). An stock i7 system pulls roughly 18A - and an average overclocked one would probably draw 20-24A depending on cooling and peripherals, so we're now at 79-83A, which is the max the PSU can theoretically provide. Seems like pushing my luck, if you ask me.

 

As for differences with 3 cards vs 2, there is a significant improvement in both real world FPS and particularly metric based benchmarks when adding the third card. The rig I just sold was a tri-SLI rig, and the 3rd card was equivalent to about 7500 points in the GPU-only score in Vantage. Not insignificant by any means.

 

This is really a big help for me - thanks. Can you tell me if the PSU uses seperate 12v rails or a single, huge one? Do they quote the amperage?

 

Thanks again! =D

Re: NEW XPS 730x Owner's thread March 15, 2010

It is with disappointment that I have found the Core i7-980x is incompatible with the DELL XPS 730x. The PC would power on but wouldn't POST (power on self test). It would power on but wouldn't get to the BIOS screen. Therefore, it looks as though we 730x owners are confined to the Core i7-975.

Re: NEW XPS 730x Owner's thread March 15, 2010

Bob, I need you to list EVERYTHING connected to any USB port on your tower, keyboard, or monitor.

 

How long does it usually take from the time you see the BIOS screen until it gets to the desktop?

How many programs do you have running in the background when you boot your PC? This will greatly affect your boot time.

Re: NEW XPS 730x Owner's thread March 15, 2010

on my 730x it takes 1 minute and 16 seconds and 24 of those seconds is just for the bios to load completely.

I have a Razer Trantula usb keyboard and a Razer Deathadder usb mouse.

No programs loading when pc boots. Startup tab of msconfig is empty. No antivirus running either. I uninstalled it to check my times but it made no diiference.

I tried a dell keyboard but no difference.

Bios has been reset to optimal defaults.

Am using a i7-965 with 6 gigs ram and Vista Ultimate 64 bit.

Re: NEW XPS 730x Owner's thread March 15, 2010

I have 3 of my 10,000rpm VelociRaptors in RAID and my PC boots in 55 seconds with a shut down time of 11 seconds. The BIOS that DELL created for the 730x is junk, plain and simple. It was improperly configured and therefore, takes forever to boot the system. The only remedy is to install an aftermarket motherboard. I know that's not what you're wanting to hear but that's the cold harsh reality of the 730x BIOS.

Re: NEW XPS 730x Owner's thread March 15, 2010

Ok...so what bios settings should i change from the optimal defaults to help speed up my boot process and what motherboard would you recommend replacing it with?

And why doesn't Dell fix the slow issues with a 1.0.6 bios update? After all, this is suppose to be a gaming computer.

And thanks for trying to help.

Leave the settings on the optimal defaults because those settings are the best for the system. As for what motherboard, I recommend the Asus Rampage III because it has SATA 6Gbps support as well as USB 3.0.  Additionally, it has support for quad-SLI...if that's your thing.

And why doesn't Dell fix the slow issues with a 1.0.6 bios update? After all, this is suppose to be a gaming computer.

 

A.) Because DELL discontinued the XPS  gaming line of desktops and in doing so, they adopted the Alienware as their gaming rig. Poor choice.

B.) Since DELL discontinued the XPS line of gaming desktops, they have all but given up on giving any additional tech support for the machines.

 

The XPS 730 and 730x was their best desktops by far, although short lived. It's a shame they discontinued the line for Alienware because not only does the XPS look better, but it's also built better.
