Lol, I forgot to look at the signature. arrowheadsmiley.png

You might want to shoot for 2133 at 9-9-9-24 then instead of 1866.

Yeah, 2133mhz cl9 on SB is doable with these sticks...pretty easily btw. thumb.gif

16GB are on their way to my canadian mate. Sicne he has a very funky 2500K with a strong IMC I asked him to push these buggers till the IMCs fall off. Although I sent them via airmail it will take some days till they are there. I am excited!

I'll give it a whirl when I get the sticks. Hopefully on friday but I ain't holding my breath knowing Itella lol

Yeah but shouldn't 3770K's IMC be better since that's what I'm getting

By quite a bit. I put 4 of these sticks on a 3770K. 2400mhz cas 10 just over 1.5vmem.

on my 2500K they max 4 sticks at cas10 at 2133. I cannot possibly lower the cas latency even though all sticks in pairs do 9-10-10-27 at 1.48

I misread your post then...you can likely get 2400mhz cl10 with 1.65v, which would be perfectly comfortable for the sticks and your 3770k. thumb.gif

Yes, but from what I understand about the asus z77 boards have more efficient mapping on the motherboard itself, and thereby giving it a slight advantage (correct me if I am wrong).

I'm not very experienced with ram OCing, when you fail to boot into windows with a lower CAS but pass memtest 4.0 / P95 blend with 1 cas higher at the same vDIMM is more vDIMM the answer some times? Ie you post but get blinking cursor at 9-10-10-27-1T @ 2133 w/ 1.5 vDIMM but boot windows and past full coverage memtest 4.0 and 12 hours p95 blend with 10-10-10-27 @ 2133 w/ 1.5 vDIMM. This is on SB with two DIMMS populated. I was thinking it was more an IMC power issue and tried playing with VCCIO and VCCSA with no avail. I came to this conclusion from input in this thread and my experiences with trying to get all 4 DIMMS stable at 2133 and the guidance I got here was 4 dimms at that freq was to much for the IMC.

I mean these sticks are cheap and if perhaps more volts to the DIMM is the answer just say the word and I'll thrash them for all their worth lol.

Try more vdimm...up to 1.7v is pretty safe, at least for my standards wink.gif
If that doesn't help you'll need a bit more vtt/vccio voltage (1.15v max on air I'd say)

Cool thanks for the info, I wasn't sure what is the "crazy person" limit on vdimm...

for vccio I'm under water with CPU only loop and a 420 rad. I've had vccio up to 1.15 with vccsa at 1.05 and 1.51 vcore, max core was 80c with IBT and perhaps 78 with P95 blend. I seem to remember some one saying stay under 1.2 vccio.
