Thanks antec for the reply here - however after looking over your site quite thoroughly I couldn't find a single piece of info on this and a google search brought me here.

Please update your FAQ with this info

Antec’s TruePower Quattro power supplies, the TPQ-850 and TPQ-1000 have way more than enough power to run an 8800 graphics card and are SLI certified by NVIDIA. The actual issue with the graphics card and System Sentinel is a communication issue. The Supply has plenty of power, but the card is not handling it properly.

This problem is not only with the Antec supply. Other brands of power supply are having these issues as well. There have been reports of power supplies from Corsair, ThermalTake, Enermax, Rosewill, OCZ, XCLIO, and Silverstone not working with these cards as well.

Nvidia SLI certified our power supply to work with the cards. Months after the launch of their card we started to have problems with the 8800GTX and the Quattro supplies. We implemented a fix at this time because we were the only company with the issue. This fix worked for any user having the 8800GTX issue.

Then Nvidia released the (G92) core series of graphics cards GTS/GT. These cards sometimes do not work with either the original or fixed version of our power supply. We have been researching the issue, and Nvidia has been testing this issue in their labs. The problem appears to be a hardware interaction. With the right (wrong?) motherboard/graphics card/PSU, this issue occurs. Many combinations work, however (we’ve got an off-the-shelf Crosshair+8800GT 512+Quattro 850 system running perfectly in our lab), so changing any of the components could possibly make the system work. It seems that a bios fix/flash is going to be the final solution, but we don’t have any definite answers at this time.

+ Rep. Thank you for the open, honest dialogue, AntecRep!

Would you please update us when Antec/NVidia has this figured out?

As a matter of fact they did, I think there were a few 8800GTS cards. They also gave away an entire Alienware system, which was awesome.

Sigh... I have the identical problem. Rev 3.0 TPQ-850 with MSI 8800GT OC edition. They do not have a known fix for this so should I just try a random PSU RMA to see if rev 3.1 fixes it? Antec has announced that both the old and new revision TPQ's have trouble with the G92 core GPU's and they do not have an answer yet, but sometimes swapping out any part may fix it. I also updated all the BIOS's for IP35 mobo and made sure the 8800GT BIOS is the newest available.

Possible new solution found!

As a last ditch effort after flashing and resetting and clearing everything I could, I searched for some beta Nvidia Forceware drivers and installed them. I have successfully run 3DMark06 twice without problems (14k score which is what my system is supposed to get) and no longer am getting the dreaded Sentinel Error. I will try some more benchies and reboot and shut down even more to make sure this is consistent and report again later this weekend.

I used the latest Forceware beta drivers from 3dguru btw.

lawrence131 · 03-07-08

OK, I have been running cycles of 3DMark06 over and over as well as restarting, shutting down, unplugging PSU, and booting comp back up and cannot reproduce the Sentinel error, and 3DMarks are consistently on the dot for performance.

It seems like Nvidia has found a way to fix this dreaded issue. I am using Forceware version 169.44.

If you are still experiencing these problems please try these drivers out to confirm that it is also resolving your problems.

+ Rep to you, Lawrence! Thanks for sharing that good news!!!

BTW - it would be helpful if you go into your profile and add your system components to your signature, so we can all see what you're running.

Hemi · 03-21-08

I can also attest to the beta 169.44 fixing this sentinel issue. This happened both my old GTX and this new GT. Sentinel power issue now resolved.....however this new driver from what I can gather while testing has x264 decoding problems, but I'll not hijack this thread with those problems.
Thank you to Nvidia for fixing the power issue.

Have downloaded the 169.44 drivers (and installed them(!) ) and I am still getting the Sentinel mem error

Anyone any advice please?
