Ampere output not enough for the GPU

Hello again


As the topic says, I wonder if the system can cause a reboot if the GPU ain't getting enough Ampere from the PSU.

I made a mistake and bought a PSU producing less than 30A and a GPU consuming 36A.

I have rebooting problems sometimes, and it just happens. Ramvoltage setted.




Thanks alot

Also another question, it seems like I am not using my GPU fully, like if there's a limiter or something, causing my GPU to only use 50% of it's capacity, is there any known thing causing this?

I bought a new one yesterday, 800W, with up to 64A output. The brand is called Tagan, tho I havn't heard about it before, but they guaranteed it's a good one and that it Might solve the problem. and it did, for a few houres till I got another Reboot. Now I am pretty sure it's something else, could it be a setting in BIOS?

tagan is ati certified http://game.amd.com/us-en/crossfir [...] s.aspx?p=3

As I wondered about this problem last night, I remembered that the in stallation of the OS occured a problem, the Comp Froze just a few minutes before it was all completed, maybe this is the cause of my reboots? Some file wasn't installed correctly? Maybe a new clean copy on the HDD of XP may solve it?

The freeze during the installation might have been caused by too low Voltage on the RAMS, but as it's set now, a complete, finished reinstall sounds possible to be a solvement

What do you think?

Also Linking a Screenshot in next message of the Temps

After some more monitoring temperatures, it has reached 60Degrees Celsius as max now. The chassis stays cool all the time, maybe another Cooler or more grease on my current one? Every opinion is welcome

What could the Rebooting be caused by then? Do you think it could be the "half-failed" Formatting the first time?

I manually set the RAM voltage to now 1.64V, and the Speed TImings is left on default tho. No, I have not run Memtest86+, but I can do that this evening, also with both Prime95 and CPuID at the same time

I think I will reformat the OS too, just to make sure it's not the problem

I am using a Corsair 2x2Gb Kit DDR3 - art nr. TW3X4G1333C9

The RAM is rated at DDR3 1333 with 9-9-9-24 timings at 1.6v. That's what it should be set to in the BIOS.

I would run Memtest86+ overnight now that you have the RAM values set correctly. The rest of the RAM timings can just be left on auto settings. The most important ones are the first four.

Yes, you have a few different options for running Memtest86+. You can either burn it to a CD, thumb drive, or floppy disk. You then boot from it and it runs outside of Windows.

You can use a USB thumb drive. You just to to www.memtest.org and click on the "Download (Pre-built & ISOs)" link. You then have a few different options. One option is "Download - Pre-Compiled EXE file for USB Key (Pure DOS)". That is for a thumb drive.

Yes, you'll need to update the boot priority to get it to work. I can't remember if you have to delete everything else off the stick or not. It's been a while since I used a thumb drive for Memtest.

So, I have putted the memtest86+.exe on the stick and set the bootdevicepriority to the USB stick, although it wont boot with the stick, any idead? thanks
