The Corsair Vengeance Low Profile DDR3-1600 doesn't overclock at all!
Hey guys,
just finished assembling my new system two days back and began making adjustments. Started with the 2500k, now it's running at 4.6GHz with voltages at 1.288V under load (offset mode). Is that okay? (lol)
Next, I moved to my RAM, which is a Corsair Vengeance Low Profile DDR3-1600 rated at 1.5V with 9 9 9 24 timings. It doesn’t overclock at all or I’m doing something wrong... I’ve tried 1866 at up to 11-11-11-27 and 1.7V, but it still wouldn’t POST. I also lowered the timings at 1.7V and it does POST, though it fails memtest at DDR3 1600... wow, that’s strange. Do other Vengeance owners have the same issue? It’s really odd because I read online reviews saying they were good overclockers with these unusual components...

I'm pretty sure your overclock is solid—it's better than mine, at least. I'm at 1.36 volts for 4.5ghz...
Don't push your RAM voltage that high, bro... those small gains aren't worth the risks!
Overclocking RAM doesn't really boost performance much unless the software you're using needs it. Then you'd have bought faster RAM.
If you still want to... keep the RAM voltage below 1.65 volts. Ideally, stick with the default 1.5v.
I understand the performance boost is minimal, but it seems my overclocker isn't cooperating lol...
Still might be worth pushing it a bit higher, which brings me back to my main question: am I doing something wrong here or did I overlook something? This Corsair memory is supposed to be a solid overclocker at least, yet it behaves like any cheap generic one that only meets its rated limits...
And regarding the voltage, I won't go beyond 1.65, I was just checking how much it can handle at 1866. Right now everything's back to normal settings. I'd appreciate hearing from others who own the same Corsair kits about their experiences.
Amirp shared his thoughts on the topic.
OJ77 mentioned a slight performance boost but attributed it mostly to the overclocker's enthusiasm.
He admitted feeling similar when he was younger and realized some activities aren't worth the time spent.
Regarding whether he was doing something wrong without checking all settings, he couldn't say.
It's great to hear you're enjoying the O/Cing ram in a Core 2 setup. You saw a big jump from 3900 to over 4700 in 3dmark11 with just more RAM. (Also, your overnight Memtest stable was solid.)
English is not my first language.
My setup includes a 2600K manualy with dimensions 100 * 40 and 100 * 45 at 1.33V, featuring load line calibration to extreme settings. I'm using the Asus P8Z68 deluxe gen 3.
I'm running exactly the Corsair Vengeance low-profile (black modules) 1600MHz RAM with 9-24 timings and 1.5V voltage. Four sticks total 16GB.
Occasionally I encounter memtest86+ v4.20 errors at 1600MHz, but it works fine with XMP/Stock settings.
At 1333Mhz there are no errors—consistent performance for 1600MHz Corsair RAM!
I need to test at 1.65V and VCCIO = 1.2V.

I noticed a small boost in RAM voltage helps steady the CPU performance. And indeed, you'll notice better results on benchmarks when you increase your RAM, though in practice it doesn't make much difference. Keep using the default factory settings.
i upgraded the corsair vengeance low profile 1600 with a minor memory boost to 1800mhz using 10-10-10-24 at 1.6v, and everything is working smoothly.
Hi evan,
I OC'ed mine to 1866 using 10 10 9 24 2T @ 1.65 v with no errors on a gigabyte 990fxa ud3 and an fx 8120 OC'ed @ 4.4 ghz. My RAM isn't the low profile.
Good luck!
