I'd like to ask the few Sandy Bridge-E users what overclock you are getting whith or without HyperThreading enabled?

I'd be interested in that, too. What I'm seeing on the overclocking boards suggests an easy overclock to ~4.8 GHz, then voltage requirements go parabolic.

I run rock solid at 4.8GHz (48 multiplier x 100 BClock, 1.400 VDC). See my signature for component list. A 24Hr stress test maxed out at 82C using air cooler. Look for more info on OC sites for your mother board.

Rick, he was asking about SB-E CPUs, not SB.

To the OP,A 4.8 Ghz OC without HT enabled was easily achieved. However, I tune it back to 4.7 GHz and run that just because most of the knowledge-base out there so far points to there being very little difference between a 4.7,4.8, or even a 5.0 Ghz OC. I use ASUS components and did my OC from their OS-enabled ASUSsuiteII. From what I can tell this is an offset OC and does ramp vcore down depending on load. I could probably get a lower vcore OC through the BIOS UEFI but at peak my CPU doesn't exceed 45C...so with that sort of thermal control I am ver pleased.

Nice OC!

Thanks for sharing Dan.Anyone else on a Sandy Bridge-E out there?

Using the automated settings on the Asus mobo I can reach 4,5 on air but started getting BSOD in FSX until I brought it down to 4.3. No more BSOD.Edit to add it was 4.5 with HT on. I now have 4.3 with HT off. CPU: i7-3930K SB-E 3.2 Ghz (OC'd to 4.3)Mobo: Asus P9X79Geforce 580 - 3gbOS: Windows 7 x641 SSD

And I amc urious to know...What about FPS ? Say for those that had an Intel i7 2600 or 2700K . Did you notice a significant better FSX experience, or it's about the same when comparing identical OC speeds? This is something that would be interesting to know. Since no one has mentioned it, I'm afraid there is probably no improvement...just guessing! ????????

Ya, I am actually not sure of the improvement. I run CoreTemp with FS and have monitored each core's use and only a very few times do they reach 100%. FSX goes below 30 fps sometimes even with core usage not reaching 100% so that must be a limitation of FSX. I think where it might come in handy is when running several things simultaneously: REX, FSC, and FSX.

Come on guys, it has been confirmed too many times: same cpu family, same clock = same performance. Only advantage is possibly faster texture loading, but gotta couple that with a really fast SSD, and that was it. FPS are going to remain the same. Only FPS kick may come out of next generation, due to another technology, clock for clock of course.

i7-3930K with 4.6 GHz OC on water cooling. Was running it with HT enabled and temps in the high 60s, but have disabled HT after the feedback that it doesn't add to performance in FSX.
