GSKILL RIPJAWS X CL7 problems with P8P67 pro rev.3 - Page 3

I will try at home 9-9-9-24-2

vccio 1.10

I will do the linx (all memory) test again.

If crashed again maybe i have to up more the vcore? actually is at 1.33 in bios, rest fo values in auto.

Will be the vcore be less if i change the memories for a kit 4gbx2? i begin to think that more dimms more vcore needed.

If you are booting up at CL9 instead of CL7 with the ram settings to auto, then it's working as some other G Skill has been due to it being rated for 2 dimms and not 4 dimms. This seems to be an issue with some of their dual channel ram kits.

I thought from your first post that it was booting for you but only at higher timings like I stated above?

If it's not booting at all with 4 dimms then IDK what is wrong. But if you can boot with 2 at a time, and then switch them so you boot with the other 2 as well. Then the problem is likely not the ram.

Yes im booting but with auto values (high).

If i set ddr3-1600 and the rest in auto, dont boot.Seems that the only value i cant change is dram voltage, i dont rember now if setting the high values as timmings boot.

Maybe need some volts more to make the memories totally stables with the oc? in auto dram voltage go to 1,65 a vccio to 1.05.

Okay, then yeah. It seems to be the problem I thought it was. It's an issue with 4 dimms vs. 2.

If you can make it faster and keep it stable by adjusting the volts as pioneerisloud suggested, then go for it. But as he already said, you aren't going to get a very noticeable increase in performance even if you got it down to CL7. You would likely only see it in a benchmark.

But as a last resort, you may be able to RMA it and get a quad channel kit that will run like you want.

I think i can sell the two kits to a friends, one kit to each friend XD

What memory suggest me to buy? i want 8GB of course now 4x2 , the ripjaws x cl8? the corsair vengeance? i think vcore at 1.33 is voltage enough to run 2600k at 4.5, 4 dimms not justified the extra volts to make the four dimms works fine.

I agree. I only went quad channel to get 16GB or else I would have went with dual channel.

As far as brand I am biased towards G Skill. But Corsair is also good. Personally I would get the lowest CAS Latency I could get with 8GB in 2 dimms (2x4). But the difference is really minimal. Bang for the buck would be higher CAS Latency. I'm just an enthusiast.

I would definitely stick to 1.5v or less though... People say that 1.6v is running fine. But just because it's running fine doesn't mean it's not having an effect on the life of the CPU. Nobody can say for sure yet since it hasn't been out long enough to prove it either way. It's all speculation. So in those cases I follow what Intel recommends if I want to extend the life of my CPU.

You don't die from smoking cigarettes right away, but I don't think anyone will argue that it shortens your lifespan. wink.gif

Actually, it's the memory itself.
If you buy a set of memory (2x4Gb), it will run fine at it's rated speed and voltage.
If you buy 2 of those same sets, they will not run at with the same timings. The timings have to be loosened, due to the amount of ram.

So your 2 combined sets of RipjawsX, wont run at 7-8-7-24
You have to loosen the timings, for them to run properly.

Thats why it will boot up and run, when you have the timings at 9-9-9-24
This means that timings of 9-9-9-24, are very close to, or at stable timings.

But 16Gb's even of the same brand and make, wont run at the 8Gb rated timings of 7-8-7-24

That's what me and pioneerisloud spent a page or two discussing already. wink.gif

Which is why you buy quad channel for 4 dimms if you want specific stock timings to start with. Like the 16GB CL7 ram in my sig. That's stock speed.

Sorry Dave, just didn't know if the OP understood everything?
Just trying to help.

No problem. I took no offense at all. I'm just happy that someone else knows what I'm talking about.

No sweat man! I'm an overclocker from years back! lol

I just wanted you to know, I wasn't trying to step on your toes!
