F3-12800CL7T2-24GBSRD compatibility question.

[Tradesman]

How about 1600, stock timings, DRAM voltage 1.63, VCCIO at 1.2 and raising VCCSA to 1.12

[JDBJG50]

Stock timings will not be stable no matter what the DRAM voltage, VCCIO, and VCCSA settings are. Believe me, I think I have tried every configuration possible over the past 9-10 months and I have never been able to get things stable at stock timings. It is both challenging and frustrating at the same time!

[Tradesman]

What is the tRFC setting itself at under auto?

[JDBJG50]

DRAM Ref Cycle Time = 110 on Auto. I have tried this up to 128 with same result. Is this the same as tRFC?

[Tradesman]

Yes, try it at about 145, may do nothing but might help

[JDBJG50]

Tman,

I tried the tRFC at 145 and still received the same result. Instability in Windows 7 and I still get errors running Memtest.

[Tradesman]

Could try an RMA, do you have another system of know anyone with a decent rig you can try the sticks in, may just be the mobo (and it's BIOS just doesn't want to tplay with the sticks nice, although CL8 is still good, diff between CL7 and CL8 is prob less than 500MB, which is negligible

[JDBJG50]

All six sticks seem to work in my friends Asus P6X58E mainboard without incident. I do know that there is nothing wrong with the sticks as I have tested each of the six sticks individually at rated timings with Memtest. I only get issues when I try to populate all four DIMM slots on my P8P67 Deluxe. Would G.Skill RMA this kit even though they work? Maybe another alternative is to sell them and try another kit.

[Tradesman]

I have a feeling it's the mobo, have you tried a slight OC, above where you are currently at?

[JDBJG50]

Best I could achieve @ 8-8-8-24 was 1620mHz.

[Tradesman]

An OC on the CPU above where it is

[JDBJG50]

I have not really played around with overclocking the CPU. I have concentrated on trying to figure out the RAM issue.

[Tradesman]

At times a bit of an OC helps things along, actually at times it's required, while 1600 doesn't normally need an OC, the CPU is a 1333 rated CPU, so a bit of an OC might help get to the lower CL since 1600 w/ CL7 is near to 1866 performance, might be worth a try

[GSKILL TECH]

For the P8P67, try a RipJaws X or Z kit, they will work best.

Thank you

GSKILL TECH, I sent you a PM.
