3770K or 3930K(4930K) or an extra 780 GTX?

post #1 of 6
Thread Starter 
This morning I just purchased an extra 3770K only to discover that the IMC isn't as good as my current one. My current one can overclock ram to 2666 mhz (command rate 2) with no issues but the CPU overclock is capped at 4.3. The new one can overclock higher 4.5ghz+ but it can't go higher than 2400 mhz for ram(These are GSkills 2666 mhz ram). Should I go the lottery for the 3770K, or just get the 3930K chips or wait for the 4930K? The 3820 works too if you can convince me. I really just want to break 5.0ghz and 2666 mHZ ram for 24/7 useage.

Well you're likely only going to be able to do 2133 on the 3930k.

IMO, keep the newly purchased 3770, run the memory at 2400 and grab a 780.

Why do you want 2666 so bad? I really doubt you actually notice the difference between 2666 and 2400, lol.

I was really wanting to buy the GSkills Trident X 2400 CL9 when Newegg had the 10% coupon code but they were sold out for both the 8gb and 16gb sets. So..I went ahead to get the next step up.

I didn't know the X79 only supported up to 2133. Wonder will Ivy-E can?

X79 is wired for 8 DIMMs, and probably puts too much demand on the IMC to go faster than 2133/2400. That being said, you probably won't notice a difference anyhow - except in memory-heavy benchmarks.

2400 is supported, but most IMCs can't get there. IB-E will be able to more than likely, all comes down to the IMC.

Just take your 2666 kit, lower it to 2400 and lower the timings.

I'd rather have 2133 at tighter timings than 2666 with relaxed cas. Running a few memory benches going past 2133 -2400 doesn't seem to make a much of a difference for me.
