Asus P7P55D-E LX & G. Skill F3-10666CL9S-8GBXL

Iggenorlin · Feb 28, 2016

Hi!

I'm in need of some support. Sitting on quite an old system for the moment and would need an memory upgrade to make it run smoother with Adobe programs.

I recently installed a single stick: G. Skill F3-10666CL9S-8GBXL - Works good.

I would like to put in another one, so 2x8gb = 16gb. One problem is that the QVL list from ASUS is like 6 years old by now and I don't know if it's even possible to put in 2x8gb or do I need to have 4x4gb? Not an expert so don't really know if each slot has to be filled up for it to reach its maximum of 16gb.

Memory: http://www.gskill.com/en/product/f3-10666cl9s-8gbxl
Motherboard: https://www.asus.com/se/Motherboards/P7P55DE_LX/specifications/

It's supported according to G. Skill, but I can't get any info on 2x8gb.

P7P55D- E LX: 4 x DIMM, Max. 16GB, DDR3 2200(O.C.)/1600/1333/1066 MHz Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture

Would really appreciate some help!

PS. If someone has tips on a smooth running system for Adobe and 3D-rendering. A midrange one and not too pricy I would love to hear your ideas.

Sincerely,
Igor

The QVL is just memory that was tested on the motherboard (they don't test every brand and model)
In the perfect world you would of bought a matched set of the memory the first time.
Buy another stick of the same memory and pop it in it should work if not raise the voltage from 1.5 to 1.55.

If one stick works, it should be able to accept 4 sticks since it has 4 slots.

gskill support :

Will it be able to run in Dual? Or would I need a "set" from the start in that case?

Sincerely,

If the two modules can work together, it should run dual channel just fine.

Now I have recieved my second stick. I've gotten the amazingly awesome and fun problem with it not recognizing my total 16gb. Only 8gb usable. Neither BIOS or Windows can use the 16gb. It says 16gb in windows and CPU-Z and all other instances. I've have tested both sticks individually and they work fine, memtest shows nothing, resetted cmos a bunch of times. I've done the maximum memory thing aswell. I really need some help here. Both modules work fine and each slot is apparently NOT capped at 4gb per slot as 8gb/slot works fine?

gskill support · Mar 17, 2016

What are the production dates on both modules? Sounds like they are not compatible with each other, you may need to send them in for a single stick of RAM. Do you have the latest BIOS?

Iggenorlin · Mar 24, 2016

gskill support :

2014 & 2016. They work in single mode with all 16gb available. ASUS support is arrogant and retarded so probably wont get anything from them it seems. The first stick is from like a year ago so I have no rights to return it really. I guess I have to take it as a lesson and be even more thorough next time.

gskill support · Mar 24, 2016

No, don't worry, we will be glad to take care of it. Send in the 2014 module, or if possible, send them both in for a single 16GB kit. That should work flawlessly.

gskill support :

Wow really? For free? Do I have to send it to the states? How long would such a swap take? Has to be the best freaking support i've ever heard of.
Sincerely,
Igor

What country are you in?

You need to start the RMA process in your country or where G.Skill provide support for Sweden. I have the same motherboard and I can't figure out how it can support 8GB modules in dual-channel mode when the total supported memory is 16 GB. If all 16GB is detected in single-channel mode, then you should be happy. According to G.Skill support, the F3-10666CL9D-8GBNT kit works fine with that motherboard (or older 4GB modules that use 16 chips and were manufactured back in 2011).

gskill support · Mar 28, 2016

8GB modules are unofficially supported, P55 and first generation Intel chip sets can support 8GB sticks, so 32GB total. 8GB modules were not available during release, so they were not mentioned. The key is double sided chips, which is why the 8GBNT kit can work because it is the last double sided 4GB modules G.Skill offers.

The motherboard is dual channel and should operate dual channel 2 x 8GB as long as you have them in the correct, same color slots.

GhislainG · Mar 28, 2016

Since you work for G.Skill, when will the list of compatible kits be corrected? As an example, F3-12800CL9D-8GBRL that worked fine back in 2011 (16 low-density chips), but newer kits (8 high-density chips) no longer work.

Any day now, it has been requested.

GhislainG · Mar 28, 2016

I made the request on December 28.
