hi everyone

its me again -______-

so i went with a core i5 3570 to replace my phenom II based system... the core i5 is used.

so i dont have a motherboard to test it, but my brother does. So i just upgrade the bios of an ASUS P8z68 LE and decide to change the 2500K and place my 3570.

at first nothing happened, and for this, my brother usses 8GB of dual channel kington hyper pnp 1866 (which works flawless with the core i5). nothing happened, no beeps, no video, only the fans running, and the mem ok red led

after remuve the RAM modules, the mother starts to beep. so i just put one stick on it and it boot up. i didnt make as much tests as i would like to do. but i realice that the memory was set at 1333 so i change it into 1600, save and restart, the system boot, it started windows but very slow. then i turned it of, and put the 2nd slot to work as dual channel. The system wont boot again

so...

1 does 1.5V memory is obligatedin the 3rd generation??

2 does the CPU is broken??? or has a fail on memory controller???

3 i reserch a lot do i need to set the memory as intel XMP to make it work as dual channel?? does all RAM supports it??

4 if i set the RAm at 1333, should it work in dual channel, i didnt have time for this test.

all seems that i will buy a gigabyte z77m d3h... it would work with my RAM, kinsgton hyper X genensis dual channel??

damn... right now i want to go to the past and just go with an FX :S

Your RAM should run in dual channel by default, regardless of speed or XMP settings. The only reason it won't run in dual channel if your memory controller is working properly is if you disabled dual channel in the BIOS or placed the DIMMs in separate channels.

If both sticks work properly on that board with a different CPU, then I'd say you do have a bad memory controller on that i5 3570. If the problems with RAM are persisting on that same board with a different CPU, then there's probably an issue with that motherboard if the RAM sticks are known to be good.

so, the voltage dont even matter??

i didnt clean the pin part of the CPU untill now, it looks fine, theres a chance to be wrong placed in the socket (which i doubt)...

if the memory controller is damaged or "bad" it can still works in single channel??

thanks for your answer i will search for bad memory controller

Ivy Bridge should be using 1.5V sticks, so that might be an issue if you do have higher voltage RAM. The memory controller is on the CPU, so you can't replace it without replacing the entire CPU.

You said that your system did boot in single channel, but that it was very slow. If that's the case, then you might not get much mileage out of trying to run in single channel mode, as the memory controller likely has issues with single channel, and it might get worse to the point it won't even boot in single channel mode.

well as far as i know this kingston RAM uses 1.65 to work at 1600 and 1866Mhz... i think it was my foult to put it at 1600 at 1.5v (i think, i didnt see the voltage) so it could be the issue with the very slow (not so solw actually but slower than the 2500k) windows start

i think i need to go with a technician and to do the test to find it out before i buy the motherboard

hi!!

of course not, it was on my brothers system... i think it was slow, as no HD2500 drivers, also new hardware always make windows sloooooooow

right now i like to think if it is damaged it wont even works... also the freqs and temps in bios were just fine

hi!... it was tested in P8z68-V LE with the last BIOS upgrade and this is the 4102

still i want to think it was a voltage issue, the motherboard is not optimiced for ivy bridge but if it find a good setting for single channel, then it must find a good one for dual..

maybe the other user burned the memory controller....

this is also interesting....

http://forum.giga-byte.co.uk/index.php/topic,6322.0.html

may be i put the ivy bridge in the socket so a pin wont make a good contact with the gold surface of the 3570 but it actually works in the 2500k or its the that the 2500k works with the mem controller on the chip set....

until now, the people only have had problems with the mem ontroller on old cpus such as athlons and the newest as first generation intel core...

well... for everyone who wants answers... i can tell you that i thoint know WTF is happening here.... today i tested in a gigabyte b75....

and the core i5 has worked FLAWLESSLY!!!!

also the guy had told me that electronic stuff work or dont work, theres no intermedium point... so the mem controller just works, as well as the CPU and IGPU...

SO in conclution:
if you have this kind of issues, just try to reinstal the CPU on the socket and try to see if there are no bent pins on it, try to be as straight as possible while you close the lever....NEVER put a non stock cooler on the CPU unless you are sure that it works perfectly fine.
