Can anyone confirm if this Q6600 FPO L640B814 is any good?

I had one. It wasn't a great clocker with a 1.30VID. 3.3Ghz with 1.43v and would not make 3.4 with 1.5v so I put it in an HTPC and sold it. Bought a L738B024 that makes an easy 3.6Ghz. Both were installed in a P5K-E and a P5K-Premium for testing.



Now that doesn't mean that your one is going to be the same as the one I had.

Here´s my contribution...regarding batches

Part I - Rig
CPU - Q6600 (L719B, L726A, L727A, L728A)
Board- ASUS P5K dlx/ Blitz Formula
Mems - OCZ Reaper 8500
VGA - HD2900XT
PSU- Corsair HX620W
Cooling - water cooling (CPU, NB, VGA)

Part II - o standard

In general they all did this:


+/- 0.02 vcore

Part III - VID

L719B
VID -1.3000

L726A
VID -1.3000

L727A
VID -1.2750

L728A
VID -1.2875

hard to co-relate VID vs better/worse overclocker...

Part IV - the reachable
3 out 4 CPUs tested run spi @4100 however, Only one went further..


Part V - FSB wall
Among the FSB walls I found one CPU max out @445 and the best was around 500


Part VI - the BEST






Note that not all settings were optimized (mems/voltages) but you already can see nice differences
