Im just gonna get that. I dont want to have to deal with this for a while.

It could also be the mobo..

 

[Julian1221]

How could it be the mobo if when I put the old video card it everything is peachy?

 

[BTRY B 529th FA BN]

It could be a flakey mobo. My old A8R32 was trouble ridden and that's the tip of the ice burgh.

 

[Julian1221]

oh ok cool. I think its time for a new psu either way.

 

[BTRY B 529th FA BN]

Good Luck

 

[Julian1221]

Thanks. I will post up my results later tonight

There are several good name brand PSUs out there in the 500W-600W range that would probably work well without costing too much.

Actually, multiple rails in general are a bad thing, as they are more susceptible to being overloaded by an uneven distribution of power than a single rail. However, many units labeled as having multiple rails really just have a single big rail internally.

Well here is a good resource:

http://jonnyguru.com/forums/showthread.php?t=3990

Multiple rails are more of a non-issue than being bad, but about everything out there has multiple 12v rails to safety distribute the current load.

Yes, it usually won't make a difference either way, but if all else is equal, a single rail is slightly preferable if only to cover those handful of odd load situations that can exist. There is no advantage to having the video card on its own dedicated rail, on the other hand.

...but you do run the (admittedly remote) risk of melting the insulation off of your cabling in case of a short. I personally tend to prefer multi-rail, my philosophy is that if you can't get it stable without overloading one of the rails, then you're doing it wrong.

Hard drives not being recognized, and onboard devices not being recognized are both tell tale signs of the powersupply not supplying enough power during startup when the BIOS runs a check on each to detect them. I got tired of being limited to only 2 HD's with my old cheapo PSU's and finally bit the bullet on a PC P&C PSU. Before, if I had more than 2, one would randomly not be detected from time to time.

You do realize that every PSU that claims to have more than a single rail is just a single rail that is split right? On top of that, single rail PSU's are much better than dua;/tri/quad/etc. rail psu's because you don't have trapped power on the rail.

Besides that it isn't the number of rails that make a PSU better it is the quality of the components used in the PSU and it's design.

Now back on topic.

Hey guys

I just put my 4850hd in last night and was having issues with it overheating. I read that I should install the Asus fan controller to adjust the fan speed and that fixed my overheating problem. I rebooted the computer and now my ethernet port says its "disconnected" and no cable is found. Am I having power issues with my PSU? It seems like when I reseat the video card the ethernet port comes back until I reboot. System specs below, psu is about 2-3 years old.

AMD 6000+
Asus M2N-E
Asus Radeon 4850HD
2 Gigs of G Skill Ram
Thermaltake 430w psu
X-fi extreme music sound card

Are we talking an actual fan controller here? Like a physical one that can be place into a drive bay so you can control your case fan speeds? or Are we talking some piece of software you didn't need in the first place?

To lower the temp's of the 4850 all you had to do was do this

One small adjustment, you don't have to create a profile for that to work, just edit profile.xml which is already there.

I'd also uninstall that fan speed control software you installed.

As far as you PSU is concerned, it is a little underpowered for this setup, if you were to replace it.

I would suggest any quality PSU in the 500W to 650W range would be plenty for this rig (600W+ would be enough for a majority for any future upgrades.)

nm, I need to read your whole post

 

[Julian1221]

Where are the latest drivers for this card? I can't find them on the site

 

[Quiksilver]

you quoted me before my edit again.

Yeah, if it doesn't turn back on barring that the fan software didn't mess with any drivers or automatically fiddle with BIOS settings then I would say you would.

theres no 4000 series drivers. are they the same as the 3?

Wrong again. In actuality, nVidia WON'T certify a power supply for SLI unless the video cards are on their own rails......sorta blows your assertion out of the water.

Oh, GOD, the old "trapped power" FUD.

How in the hell is there ever trapped power on a rail? Please explain that to me.....


My assertion is that there is never trapped power on any rail.

Why do I say that?

Simple. Take this power supply.....

Silvertone 1200W 6-rail power supply


Each +12V rail is rated for 17A.

If I believe you, I have 17A on each rail trapped....meaning 17A is just coursing through each rail, essentially sitting at the connectors, waiting to be used.


But if you add up all the rails (6 x 17) you get a total of 102A or 1224W, which is more than the entire output of the power supply's rating, never mind that the +12V combined is only 95A, or 1140W.

So where is this trapped power? If I'm pulling 15A on each of the six rails, I get 1080W. But, if I pull 17A on just 4 rails, I pull 816W total so far, or 68A. That leaves only 27A for the other two rails......so if I pull 17A off another rail, I have only 10A on the last rail.


Granted, these rails are a little down on power....below 20A.....but the reality is that no matter what each rail can deliver, the total of all rails max amperage always adds up higher than the total +12V wattage, or amperage, the power supply can deliver across all its rails.

Essentially, a power supply will deliver required amperage and wattage to whatever the rail is being asked of it until that particular rail hits its overcurrent protection. If you max out the amperage draw of that power supply over four rails, and it has six, the other rails have NO POWER to supply....pure and simple. (Well, not so simple....you may be able to get 3.5A out of the remaining rails, but that's about it.)

There is no such thing as trapped power. That's just a bunch of FUD "invented" by a well known power supply company when it switched from a multiple rail setup to a single rail setup.....after it horribly failed in its design of that multiple railed Turbo Cool 1Kw power supply and had multiple failures and such.

Use your brain, not marketing FUD, and think for yourself.

Wow. You need to take a chill pill. :roll:

What the GPU companies certify or do not certify has little relevance to what actually works in practice. There are plenty of uncertified units that work perfectly fine and provide equally good voltage regulation. The same applies to their official single GPU requirements.

Anyway, the purpose of that restriction was to exclude the early EPS-like dual rails that put the ATX/CPU plugs on one rail and everything else on another one, not single rails.

Note the 33A rating on the 12volt line. That's the important number. Corsair is a very solid brand.

:thumbsup:

Whether the PSU has 430W, 600W or 1000W, the important number is how many amps COMBINED and SUSTAINED on the +12v rail(s). That Thermaltake the OP has is quite anemic for +12v power. For lots of +12v juice, Corsairs are good, followed by Antecs (whether TruePower, NeoPower or EarthWatts) out of the brands mentioned in this thread.

As for single rail versus dual rail, for the most part that's a non-issue. It "became" an issue due to some FUD a couple years ago from one company.

As soon as I am out of here im gonna jump on a corsair

 

[VirtualLarry]

Hmm. I have two machines with E2140s @ 3.2Ghz, Radeon X1950Pro, one HD, one DVD, 2x2GB RAM, and ThermalTake 430W PSUs. I bought two 4850s, and I also bought two Antec EarthWatts 650W PSUs for $70 ea at Microcenter. I plan on using those to build two Q6600 quad-core rigs along with the 4850s. Unsure if I'm going to crossfire on one system or split them between two systems.

I know your talking about PC Power and Cooling, but that wasn't where I heard it from.

Clarify for me please, cause I'm still a bit lost.

Say you have 2x 12V rails at 18A each. Now let's see one device needs 12A and another device needs 24A. Sames each rail is only rated for 18A and one of them only is using 12A, would the power be diverted to the other rail and used for the other device, or would it be "trapped" as I said. :S

It's not marketing FUD, as I heard it, I read somewhere about this; and thought it to be true.

Absolutely wrong. All of these PSU's are nVidia SLI-certified, and not one of them has more than one +12v rail.
