Is KVR13N9S8/4 compatible with KVR16N11S8/4?

[zedec.pacaldo]

Help!!! I need more ram but it seems like I can't find the same model for my ram which is KVR13N9S8/4. The only thing available that's closest to my ram is 4GB 1600 Mhz from Kingston (Same Brand and also Low Profile). Will this have issues if I run 2 KVR13N9S8/4 and 2 KVR16N11S8/4? Since the Voltage of both sticks are the same, Latency is only different. What do you think?

I also saw another similar RAM with same brand, voltage, and also low profile. KVR16N11/4. Will they work together too?

I don't mind if the 1600 Sticks will underclock to 1333. Just want it to work without issues.

The only way to guarantee that it will work without issue is to get a kit, sell what you have and buy the bigger set. In all reality, it most likely will work, and if it doesn't work out of the box, there are people on here who can help you get it running, but here's the thing. Memory problems can be really tough to diagnose, and if it's something that only happens once a day, it's enough to be a pain, but not really enough for us to guess at what's wrong unless we test other things first. A G.Skill rep told me that different similar memory can be incompatible even if it's really close, the underlying tech can be very very different when there's years between when you bought the first module and when you looked at the second. Worse, there's no way to tell what you have and even the same part number might be different underneath.

They can be both same model, same type, same timings and same brand, but different week of production and it might already be enough not to work right. And then you have the opposite spectrum - basically everything different, but still works at lowest clock speed. No guarantees for anything when mixing RAM, it is a game of luck.

I have the exact 2 ram(kvr13n9s8 and kvr16n11s8) they are working properly, until after 5 days of using them together in my gigabyte f2a68hm-s1 mobo, the kvr16n11s8 is the problem, when I start my pc for few minutes its okay no problem, 8gb is still detected in my pc, but after a while the pc shows the blue screen of death and restarts, after the restart it can only detect 4gb the kvr13n9s8 ram.

I suspect that the kvr16n11s8 ram that i got is faulty, because for a few days its working pretty well no problem. What do you guys suspect in this situation?

The post above you already explained that you shouldn’t mix ram types so that’s probably your issue. Apparently they do not work together

Yes? But they worked perfectly fine for 5 days, I mean, if they really are not compatible then they shouldn't have worked at the first day that I used them together.

Check your update history and see if you had an update between the last five days now but I still don’t recommend mixing ram

I did and the last update was Microsoft Security Essentials this day, roughly the same time I had the blue screen. Interesting. Do you think that's causing the problem?

This is indeed strange. Have you tried running a Windows defender virus scan and let it scan everything?

If you have system restore enabled try to restore to the day before you had a problem or before that

Do you think Microsoft Security Essentials update affect this?

Is that possible? A system update can make a ram faulty?

Run memtest 86 on the memory

The situation (problem) is that you have
4GB 1Rx8 512M x 64-Bit PC3-12800 CL11 240-Pin DIMMs
and
4GB 1Rx8 512M x 64-Bit PC3-10600 CL9 240-Pin DIMMs
in the same machine which, depending on your timing settings, may or may not work well together.

You can try backing your timings off to 11-11-11-11 @ 1.5V, and see if it's stable; or you can replace the memory with a matched pair that have been verified to function together.

Do you think while running memtest86, bluescreen can occur? I'm scared to lose files.

No but if you see errors you’ll know your memory is not working and like stated above since it’s Mismatched it’s probably not working correctly
