Is there a faster way to test RAM than memtest86+?

I have a couple of PCs with 8GB of RAM and for quick checks I'm using an Ubuntu live CD, but in case of troubles I have to resort to memtest86+. However, memtest86+ is taking quite a while to complete.

Is there a faster way to test RAM?

Update

From the changelog for version 5:

  • Optimized run time for faster memory error detection

No. But you can stop memtest after Test 6. If everything passed until this moment, there are high chances your memory chips are OK.

Note that memtest doesn't work on some Macs.
