Corsair Vengeance 8GB 1866MHz C9 Review

[Lightman]

I won't pretend to be a PhII/memory guru as I stuck with a S939 till early last year, but I've been doing an insane amount of reading lately as of having horrible luck with both. AMD systems apparently need more voltage than what the kits say (since they are mostly centered around Intel stability) so you're fairly low with 1.55V. Also you shouldn't have too much trouble making those speeds at a higher HTT clock, but I know what you mean for sure heh After a few hours of work today on trying to get 1900MHz to work (futzing with voltage, timings and Drive strengths) I find that 7-8-7 @ 1700MHz to be this system's happy place. That leaves my CPU@3825, NB@2805. I was going to see what NB@3125MHz resulted in, but forgot :\ Frankly, I don't even know if she'll get into windows at that NB, but I know it was what it took to even get 1900 to POST, the few times I manage to. This 1090T is still relatively new to me, having also came from a 555 heh I do know these modules I've got a bit defective as the site owner of where I edit wasn't able to get them working at their 2200MHz rated speed, so I don't even know what their max is, with 1833 being the most I've been able to get out of them. I also don't know good these ICs are that Kingmax got (rebranded PSC apparently).

Anywho I'm glad a few people are showing similar results on these Vengeance kits as I was debating it!

Yes, you're right. I ran these sticks at 1.6V initially but after a bit of play with them I figured 1.55V is enough to get them stable for what I need and because lately thanks to bitcoins I run my PC 24/7 every little power saving counts. They were MemTest stable @1.525V but I like to give it one up just to be on a safe side. I rather have a bit slower PC but stable for everyday use than crashing Windows every now and then.
When I'm in a mood to bench be sure DIMMs will get 1.7V and my CPU will scream 4.2GHz+ @1.55V on 6 cores, but for Crysis 2, EVE, and online browsing 3.65/4.1Turbo is a sweet spot at default volts for me

My PC idles 200W and slightly pushed tops 750W without major OC above my 24/7 Still 100W reserve in my PSU before it goes pop!
