Floyd, are you still using that Rosewill RP 550-2 PSU?

And are you still using that GTX460/GT430 video setup?

Cheers.


Yes , But the problems started before I put the GT 430 in the PC...

The thing is that that PSU has 2x 18amp 12v rails and if I remember rightly a GTX460 requires about 20-22amps (depending on the model) so you possibly have at least 1 of those rails over its maximum limit under full steam. Now the other rail with that processor would be getting pretty close as well and fitting that GT430 would be adding that much more load to it again.

Now even if that PSU can revert to single rail operation when 1 rail is overloaded, which I can't say that it can but even if it could the total output wouldn't be over 40amps, more likely around 38-39amps.

I've seen some strange behaviour from systems that are under powered and yours certainly fits the bill. Personally I would've gone with a PSU that will deliver at least 45amps on a single 12v rail (50amps would be better again).

Cheers.



Your right wiggo no where near enough power you need to get at least a 700wat psu I run a 700wat and no prob's 550wat won't cut it

Yeah that is cutting it close and could be the source of the problems, not enough power.



Well , If that is the problem , then there is nothing I can do about it for a while. Be at least a few weeks before there is any chance to buy anything else , and still eat anyway... LOL

I wouldn't go that far but an Antec High Current Gamer 620w delivers 48amps and a Corsair TX650 delivers 53amps which are the PSU's that I use here for builds, upgrades and replacements for similar hardware setups (my own 2 rigs use Corsair TX850's which deliver 70amps).

you could try not using the gtx and use a older card .Or disconnect all usb's and only have 1 h/d no dvd roms or any thing else no wirless cards nothing only use what is on the m/b

Remember nvida recommend at least a minimum of 450wat just for the GPU's

This is the GTX 460SE 1 gig version... one HD and 1 DVDrom , thats all , no other cards or anything.
Either way , if not enough power , then There is nothing I can do about it at this time.

I'm sorry to hear that but I'm betting that this is your main problem.

It looks like that 460SE draws about 2amp less than the standard 460 but still enough to be a problem.

I'm not sure about the prices there but the Antec is the cheaper PSU of the 2 here but then you will have a greater variety of brands to chose from over there too.

I just hope that the possible lack power draw through the motherboard hasn't effected it as I bet that its power delivery circuitry would've been running warmer than it should have.

Good luck with it anyway.

Cheers.

Floyd my second back up machine is a core 2 duo 1gig or ram I h/d 1dvd burner psu is 500 watt and the gpu is a gtx 220 nvida recommend a minimum of 400wat for that gpu and I do not have to plug any power to the gtx 220.

just one more thing it is always better to have to much power than getting something that will just do my experience with psu's is if it just does the job it won't last any longer than about 18 months the one I currently have is 3 yrs old now and I have 3 h/d 2 burners is a quad tv card wireless card and I only start to have trouble if I connect more than 5 usb's anymore than that it starts to get problems

I Tried this new Ram , like they told me to do.
Disabled legacy USB Support and set to 2T .
When I put Both Sticks in PC , I had no Video , PC seemed to Boot ok , Just NO Video.

This Asus MB has a button on Board called Mem OK

"Quickly ensures memory boot compatibility."
So I pushed the button , and it would boot , but the keyboard quit working , I had video , just no keyboard... LOL

When I went back into Bios and checked settings again , the mem timing had changed back to 1T .
Now... It will boot with just 1 stick of ram... Not with Both sticks... LOL
I am giving up on this for now... I will go ahead and pay corsair the 43.00 for this ram , since they keep telling me that it's not the ram at fault.
I had to borrow the cash to do that.
I'm not sending back the old ram , because at least I can use my pc with the old ram in it , just can't crunch with it...

I have re-enabled Legacy USB support , so I can at least use my pc.

Maybe the PSU is weak , There is nothing else I can do for this PC at this time.
If things change , I will come back to S@H and crunch away...
Until then... Good Bye , There is nothing else I can do , I won't run a system that is producing errors.

Yes Floyd that is what is happening your psu can't handle things a classic sign that you are right on the edge of what the power supply can handle . Do you know how much power the CPU uses . The machine running flat out will chew approx. 90 watt for the CPU then there is the fan or fans 100 watt each the h/d 200 and you still need power for the Gpu it all adds up . I'm not shore if the wattage I have stated is correct you will have to check that with the manufacturers but it all adds up and then you have to remember how old the psu is as they lose there efficacy over time so a 550 watt today may only be able to give you 540 in 18months time if it's always at it's maximum then that may be 540 in six months because it is being stressed you should aim for about 60-75% of max power used so it's not stressed

Think of it this way get in your car and red line the motor how long will it last ??? but if you never red line it then you will get 200,000 miles instead of 20,000 because you red line it well power supply's are no differant

I was having problems with my system after ram added, a BIOS update was required. May want to check with the MB vendor.

I got the newest Bios update when I got this MB on the first part of April.
Bios update # 1602 2/25/2013
That's what the MB paperwork said to do.

I am trying to just run 1 GPU and 3 CPU tasks at a time , see if that takes some of the strain off the PSU , maybe enough to crunch at least some , until I can get another bigger PSU.

Have cache set to .25 days till I see how it is going to work.

It is unlikely that only running one task on your 460 will save enough power to give you a stable system. The reason being that its often the burst power that is demanded for a very short period of time that casues PSU to fall over if they are a bit marginal. I would stop GPU processing until you have a decent PSU in that rig - at least 500W, and preferably a bit more given you are using an AMD processor, and they can be quite power greedy.

OK, I know Nvidia say 450W is "sufficient", but I had problems on this rig with a "good brand" 450W PSU when I first put the GTX460 in so went up to 600W, and its been stable ever since.

I seem to recall a number of other symptoms, from other posts, that would indicate there was a different problem. Start-up read errors, BSOD when expanding Win 7 install files, etc. Since there are a few threads about the same machine, it's hard to keep track. Or maybe I'm mistaken. Is this the same machine that Blue Screens when expanding the Win 7 install disk?

Yes it is , I have tested the ram and with 9 passes on memtest it shows as good , no errors , so somebody said that maybe my 550 watt rosewill psu might be going out. It is about 6/7 years old , and was used when I got it then.

I had this show up one time...:

Unhandled Exception Detected...

- Unhandled Exception Record -
Reason: Access Violation (0xc0000005) at address 0x6380EDD9 read attempt to address 0x00000000

Since the ram tested as good...
It was said that maybe the PSU is getting a bit flaky...

not giving enough power to the components of the PC.
I'll be honest , I have no definite Idea what is causing this intermittent problem.

Not being able to install an OS is a pretty critical item. For most people that would be a show stopper. I doubt a weak Power Supply would cause that problem, it could, but it would have to be so weak that running SETI at all would be nearly impossible. That doesn't appear to be the case. You might want to concentrate on asking Corsair about those BSODs when running the install disk. Those BSODs point to a ram problem, no matter how many times it passes that test. My Intel board passed that test too, it was still the ram, the same ram that runs perfectly fine on my ECS board. Try testing the install disk again. To be safe you would need a different HD, I would remove the working drive you have and test the installer on a different drive. Until you are able to run the Installer successfully, there isn't any point in proceeding with anything else, IMO. Like I said, not being able to install the OS would be a Fatal event in most cases.

When I get able to , I plan on getting a new HD , a SATA 3 version ,Then do a clean install of the OS , and if that works I'll use that for the Boot sys , and keep this older drive to be used as a back up drive.
This new ASUS MB was built for the newer drives , that may be part of the problem also.

I'm just hoping for the best and grasping at straws right now !

I was suspending Work several times trying to get boinc tasks set up and I read somewhere on here that that will sometimes cause a compute error .

I will wait for a while and see if it repeats ,I hope not...!

As far as I know, all SATA controllers are backwards compatible, Backward and forward compatibility. Considering you've already exchanged the drive, the chances of the HD causing the problem is extremely remote. You can always call ASUS and ask their advice. Make sure you tell them about the problems with the Win 7 Install disk. As a side note, neither of my machines that passed the ram tests, but still had ram problems, gave any problems with the OS installer. The problem with the OS installer is a huge red flag.
