Memory timings for 4790k

post #1 of 3
Thread Starter 
Hello everyone,

I recently upgraded to an Intel 4790k from an AMD fx8350. I've been chugging along fine, and I've been gearing up to overclock this bad boy. I had a 500mhz OC on the 8350, and that thing ran perfectly stable for a couple years. I'll be looking to bump the 4790k up to 4.6 for starters and then see how much further I can go from there.

The issue I'm facing is my RAM. Its 8gb(2x4gb) of Corsair vengeance 1600mhz RAM. It's perfect for gaming, but I'm finding that I need more for some of the school work that I've been doing which requires running a couple VM's, Eclipse, and tons of other windows. Therefore, I've been wanting to upgrade to a 16gb(2x8gb) kit for a while now. I'm new to the concept of changing memory timings as I never had to do so with the 8350, just had to feed it more power lol. I was wondering if there are any particular timings/speeds that I should steer towards in my purchasing decisions that yield better stability for devil's canyon chips? Any other recommendations such as brands to look for, brands to watch out for, etc? Keep in mind, I'm asking specifically as they relate to devil's canyon 4790k OCing, not a general who's who of RAM.

Thanks!

Well for a i7 4790K, 2400MHz RAM sticks run pretty well. Make sure you get a kit of two and not four as that will put more stress on the IMC and make it harder to run higher clocked RAM.

Thanks for the input benjamen50. Do you have any experience with changing timings to improve stability? If I understand it correctly, you actually slow down the RAM timings to increase stability on the CPU (ie increase the cycle time that the RAM is accessed). This reduces stress on the memory controller that is being forced to run at a higher clock and increases CPU stability allowing you to push it a little further? <<Asking for verification tongue.gif >> If so, are there any factory timings that are already better suited to overclocking a 4790k? I can't seem to find much info on the topic...

Thanks!
