TechTool Deluxe on new iMac i7 - FAILED VRAM TEST

[iMacKeung]

OK I've encountered two times that these screen flickering / momentarily blackout issue since I got the new i7 iMac

but I would say it happens quite rarely and is easily resolved by a reboot

Just now I opened up the TechTool Deluxe that came with AppleCare and ran it, and the VRAM test failed, even tho I am not having the flickering issue for now

it didn't say the reason tho...any of you have the same results?

Before you wig out run an apple hardware test from your gray restore discs and keep in mind that while tech tool is highly useful, there is a small (very small) chance that it is not yet recognizing your i7's components. I know that is wacky but weirder things have happened.

I agree with jessica.. It may be that the hardware just isn't recognized.
