F3-12800CL8D-4GBRM / Asus P7P55D Deluxe / i5-655K => no POST

[Hubreeve]

Hello,

I have 2 sticks of Ripjaws F3-12800CL8D-4GBRM and tried to install them into Asus P7P55D Deluxe.

However, the motherboard will NOT POST. I tried one stick in each slot for all 2 sticks. The motherboard will still not post. I even tried various combination of 2 sticks in the slots. Still no post.

I also tried pushing the MEMOK button, let it run, and reboot. However, after its designated cycles, the DDR LED is a solid red. Still no post.

I also tried clearing the CMOS, pushing MEMOK, but still no post.

Now, I know that the ripjaws are not included in the the Asus Qualified Vendors List. But the motherboard is included in G. Skills qualified motherboard list on G. Skills website.

Is this a question of compatibility with the motherboard?

Or are all 2 sticks of ram DOA?

I don't thing the motherboard is at fault because I tried it with no memory stick and I've got the 3 beeps indicating "no memory". Is this exact ?

Please help.

Thanks

Hub'

I have the same issue with a new -e pro version of your motherboard with the cl7 version of your ram. They worked on my previous -e pro board but won't post on the new one. I have tried the same things as you.

So although it isnt stated on the list for asus it does work fine normally.

Have either of you tried other sticks in the mobo to check the mobo itself? If it will post with different sticks then probably the sticks otherwise prob the mobo

Hi,

Thanks for the answer : I tried with Kingston stictks and got the same => no POST : I can suppose that the G. Skill memories are not in fault. I'm now going to the P7P55D deluxe forum of Asus.
Thanks a lot for your help.

Good luck with it, one other thing you might check is to ensure the CPU is seated properly and both sets of power connectors to the mobo are tight - have seen similar problems because of these items

Thank to you :
both sets of power connectors to the mobo are tight ;
the processor is properly seated ;
i can't control the processor because i haven't a replacement one;

Might try booting w a single stick and turn off the the USB 3 controller....check the posts by MikeH here in the forums....am going to try and 'borrow' a P55 system from a lady I know to look into these (many, many), P55 problems from the last couple of days. Be back in the PM

[Hubreeve]

Thanks for this option, but i can't boot so i can't disable USB3...

Let me know what you here from ASUS, if you would. If the Kingstons didn't go either, if you have or could borrow a different PSU, you might try that (i.e. it may be bad itself or have a bad cable. Also check that the mobo is firmly attached to the case at all mounting points so no shorts, might even check the CMOS battery, just remebered, a short while ago we had an ASUS that wouldn't POST at all (brand new), had a dead CMOS battery. Will see if I can think of anything else and check back in about 4 hours or so.

Hi,

The cmos battery was already tested and is ok. The psu was tested cable after cable and everything is ok. I'm waiting for answer of asus forum but... it require a lot of hours before getting a answer.

Replace the motherboard, a new one should work better.

Thank you
