Corair Vengeance Overclocking thread.

Corsair markets this as overclocker's memory so curious what people are getting out of them. If you have validation, screenshot, or benchmarks please post it.

1.5v
Aida 64:
22,117 MB/s Read w/ 41ns latency

1/15/2011: Was able to lower the command rate from 2N to 1N and tighten the timings. No luck getting to 2133.
Going to leave it here until the newness wears off:

Edit: 1/26/2011: Above was not stable. Ended up going back to stock settings.

Looks good. Your 2600K overclock is awesome at 1.328v for 4.8GHZ.

I noticed this about Corsair 1600 RAM (listed from lowest to highest in MSRP)

XMS: 1.65v
Vengence: 1.5v
Dominator: 1.65v

Other brands have 1.6v.

What exactly are the effect of these voltage differences? What's the best for overclocking on Sandy Bridge?

It is not stable. I played Black Ops for several hours last night without issue but OCCT fails out before 5 minutes of the stress going. Best stable setup I can confirm is 4.5 at 1.24v.

Using 8GB DDR3 1600 Vengeance. I hadn't done alot of tweaking. Yesterday I ran some burn/stress test. Stable. Probably tweak a little bit more later.

My setting is stable at:
DDR3 1866
9-10-9-27 2N
1.55v

It failed at:
DDR3 1866
9-9-9-24 2N
1.55v

Is that even possible? I have had 3 friends including myself with 4.7-4.9 ghz three separate batches, all had to run min of 1.38 volt just to get it stable? Are you sure you are not reporting the speedstep voltage downgrade?

You are probably not going to be able to push the memory controller that high if you are already pushing 4.8ghz. The stock memory controller supports 1333. I am using the 16gb kit and using the XMP profile for 1600 and its fast enough for 16GB of ram.

I ran into random stability issues after shutting the machine down. Never crashed while working but occasionally I'd get a "Failed Overclock" when cold booting or returning from sleep. All attempts failed to get it stable @ 4.7+ while keeping the vcore @ 1.4 or below.

Stable at 4.6ghz 1.33 vcore now for the last several days.

Don't think it makes any difference in real world usage, but I tweaked a bit with following:
