Not true. Later versions (680i SLI A1/T1) had GTL voltage modifications which allowed for Quad overclocking. The LT versions did not have this fix, neither did the AR/TR versions.
Directly from EVGA
To clear things up for everyone asking how you can tell the difference with the EVGA 680i SLI boards with the fix for the Intel Quad Core CPU; EVGA will be doing a small change to its part number for this particular SKU.
EVGA will modify the last digit of its part number to reflect this change
122-CK-NF68-AR will be replaced with 122-CK-NF68-A1
122-CK-NF68-TR will be replaced with 122-CK-NF68-T1
More information backing this up, including overclocking results, from Ericeod's 680i Overclocking Essentials thread
I also had an EVGA 680i SLI A1 board, and was able to overclock my Q6600 to 3.6GHz @ ~1.47 V-Core, 12 hours Orthos Small FFT's stable.Edited by Choggs396 - 12/19/08 at 7:10pm
