Core i7 Overclocking by Batch #

i7-920 3841A383 from Newegg:

These are all with LinX x 20 and Prime blend stability:

4.0ghz (20x200 turbo off) @ 1.30000v bios, 1.264v load with HT off, 1.335v QPI, 8-8-8-21-1T, 1.65v DRAM (1.66 BIOS), max LinX temp 67c on TRUE 120 push-pull
4.0ghz (20x200 turbo off) @ 1.40625v bios, 1.360v load with HT on, 1.375v QPI, 8-8-8-21-1T, 1.65v DRAM (1.66 BIOS), max LinX temp 83c on TRUE 120 push-pull.

Edit, added recently:
3.8ghz (19x200 turbo off) @ 1.21875 bios, 1.184v load, 1.20v idle, HT enabled, 1.275v QPI, 8-8-8-21-1T, 1.65v DRAM (1.66 BIOS), max LinX temp 63c on TRUE 120 push-pull. I got HT disabled down to 1.154v load I think for LinX but I had to bump it all the way back up to 1.184v for Prime blend even with HT off.

Higher voltages were required for Prime blend stability vs LinX x 20 even though LinX has highest temps. I think this is due to memory system load because I had to increase vQPI a bit for HT as you can see.
