[SOLVED] DDR3 2x4GB Kingston RAM and 2x4GB Samsung RAM in H97

[tbalint3]

Hello Everyone,

I had the opportunity to get some free RAM modules (Samsung DDR3-1600MHz 4GB modules), and I would like to ask if it is okay to do the following:
I have an old(er) H97 chipset based system which previously had only 8GB RAM (a Kingston DDR3-1600MHz KIT) in dual channel. Now upgraded it to 16GB in the following configuration:
2x Samsung M378B5173QH0-CK0 = 8GB
2x Kingston KHX1600C10D3/8G = 8GB

Now I know it is generally not a good idea to mix different RAM modules, but since these are really similar modules (same freuency, same voltage), I would like to ask: Is this okay to run the system in this configuration?
I am attaching a CPU-Z generated report too with the details: https://drive.google.com/file/d/1JAiFdUY-FBloiVIDFU1dWHxHhD70C6KO/view?usp=sharing

Thanks

Is this okay to run the system in this configuration?

The eternal RAM question, asked here multiple times per day.

The answer never changes.

It might work, it might not.

Does the machine boot?

If so does the machine see all the ram and the proper speed?

Will the machine run memtest86 for a few hours error free?

Yes, everything seems to be perfect. I let memtest86+ 5.31 run almost 3 hours and it passed test with no errors.
System is stable and fast, and aida64 and windows 10 reports the correct values regarding the RAM speed.

Looks ok.....run it.

Great! Now I have another question (I hope it is not too off-topic here): I am also planning on replacing the CPU to either a i5 or i7 Broadwell (5675C or 5775C) as it is a bit faster than Haswell and consumes less power as well.
But on Intel's datasheet: https://ark.intel.com/content/www/u...55675c-processor-4m-cache-up-to-3-60-ghz.html it says it supports DDR3L-1333/1600 @ 1.5V memory.
I think DDR3L is 1,35V and notebook only memory, so I am bit confused. Do you think Broadwell CPUs can work well with my RAM?

Your link looks like garbage to me.

Since memtest runs, you are good on ram.
DDR3 and intel is relatively tolerant of unmatched ram.

What is the make/model of your motherboard?
What is your current cpu?
CPU-Z motherboard tab will tell you.
Make a note of the bios level since it may need to be upgraded for a new processor.

Does the mobo show support for the new cpu?

 

[tbalint3]

I don't know why the link wouldn't work, I can open it just perfectly. It contains some screenshots in a publicly shared Googée Drive folder, since I can't figure out how to upload photos directly here.
Anyway my motherboard is an Asus H97 Plus and my BIOS is ver 2603. Broadwell is supported according to Asus: https://www.asus.com/hu/SupportOnly/H97-PLUS/HelpDesk_CPU/

My current CPU is the "smallest 4th gen i5", the haswell i5-4440.

So, here are the RAM modules' specifications:

Kingston (Hyperix KIT):
KHX1600C10D3/8G - DDR3-1600MHz - latency (CL-tRCD-tRP-tRAS-tRC @ frequency ): 11.0-10-10-30-39 @ 800 MHz

Samsung RAM:
M378B5173QH0-CK0 - DDR3-1600MHz - latency (CL-tRCD-tRP-tRAS-tRC @ frequency ): 11.0-11-11-28-39 @ 800 MHz

So basically the Kingston is CL10 while the Samsung is CL11
And the BIOS set these timings automatically: 11-11-11-30-39 @ 800MHz, so I guess it configured itself automatically to the slower (Samsung RAM). The two Kingston is in dual channel A and the two Samsung is in dual channel B.
My question would be: is this an ideal way to run the system? I have run since another memtest, this time for 6 hours and no errors were detected.
I leave everything on 'Auto' setting in the BIOS.

Ram speed.....unless your a benchmark type looking for every drop of blood I doubt you will notice a diff.

You have gained ram amount.....run it.

says it supports DDR3L-1333/1600 @ 1.5V memory.
I think DDR3L is 1,35V and notebook only memory, so I am bit confused. Do you think Broadwell CPUs can work well with my RAM?

DdrL is just a lower voltage ram, not specific to laptops. Just means the xmp profile is set for a lower voltage, in this case 1.35v is supported. Early DDR3 was 1.65v, later changed mostly to 1.5v,but there were some L sticks out there too, although not many.

It didn't slow the pc down, memtest passed. In a nutshell, there's no other reason to worry. Mixing kits really only applies to ppl thinking about buying a second kit as it stands a decent chance of being wasted time, money and effort. In your case, money isn't the object, just some time and effort, and if it didn't work, you haven't really invested much overall.

As long as the ram is S-K-S-K or vice-versa, you are good. Ram always defaults to the loosest timings, highest voltage, slowest speed when mixing kits, but there's no real loss between C10 and C11. C9 to C11 would be more noticeable.

thank you for your answers, guys. I learn a lot

 

[tbalint3]

Thanks everyone, I will just use it as it is now. Running Windows 7 and 8.1 VMs with 16GB RAM is so much better.

 

[Karadjgne]

Oh, lol, yes, VMs require ram. Generally you want 8Gb for the source and a minimum of 4Gb per VM when adding up potential usage.
