upgrade to 24gb ram

[HuNTeR-]

cheers.
I have mobo p8p67 pro rev 3.1+i7 2600k processor and I have 2x8gb ram 1866 Fury black with cl 10 1.5v.My mobo have 4 slot of ram and I want to add another 2x4gb 1866 same Fury black to make 24 gb total of ram.It is possible without any issue?I check on manufacturer site and support max 32gb of ram.
I want to upgrade to 24 gb ram because 16gb nowadays is minimum and in task manager sometime I have ram usage very high 70-80% with one mozila open+one chrome open.
Any opinion pls?thanks,

I can't see why there would be any problem.

Like LTC8K6 already said, it should work just fine.

However, you have something(s) else running in the background, as the OS and one Firefox and Chrome tab will not consume 70% - 80% of 16GB of RAM.

70-80% with 16gb? You got 200 tabs open or something?

The most likely explanation is that the 80% contains both the active processes and all the caching and buffering by OS. Only the memory used by processes does count. The cache will be flushed by OS, if the applications need more RAM.

One could go as far as say that the "desired usage" is 100%. Unused RAM is wasted RAM.

You are likely correct on that.

My main PC has 16 GB of RAM in it, and I only restart it about every 3-4 weeks. I noticed as time goes on, more of my RAM shifts into the "standby" mode, so maybe that's what they think is "using 70% - 80%" of their RAM? And this is with my PC seeing mixed use during that time; gaming, Folding@Home, browsing, documents, etc.

8 GB is really the new "minimum" for most Windows 10 desktop users, with gamers, enthusiasts, and professionals more in line with 16 GB being the new "minimum". However, all they stated they used on their PC was one Firefox and one Chrome "single tab" session, and 8 GB is more than enough for that.

kaspersky+grw+rammap=84% usage.is still enough 16gb in 2019? :|

You've got something else running. I have Norton Internet Security on my PC, and it isn't a light program. In fact, the top two utilities listed above are using around 2GB themselves. You also seem to be using all 32 bit programs, is your OS install 32 bit as well? Just asking because 32 bit Windows 10 is limited to using 4GB of RAM.

Do a snapshot just with Windows task manager and resource monitor (and close those two utilities out). Finally, I see an active torrent also running, plus other processes you must have added like "AddGadgets").

Here's my Dell laptop which "only" has 8 GB of RAM. Even with Samsung Rapid Mode enabled, and with the various Dell utilities, I'm still sitting at around 50% usage. You have many processes running that I haven't seen before. Items like "WebHelper" and "AddGadget" (along with GRW and RamMap) are likely using your memory.

A Firefox and Chrome session, along with with Kaspersky will not use anywhere near 16GB of RAM.

The only thing I can figure is he has tons of small garbage programs running because even without Wildlands and rammap it would be only 2gb less. Even with 2 browsers running on my 8gb laptop I'm using less than 50%

True. Something is not adding up from their screen grab. Something is using up the RAM (and even the CPU usage is at 30%). While the 2600k isn't the latest/greatest CPU, it still holds its own again current CPUs all these years later, so that shouldn't be the issue. I wonder if the OP uses a SSD or a spinner for their OS as well, as Windows 10 is SLOW on a HDD as well.

It could even be something like malware or PUPs running in the background / startup based on what they showed was running on their PC.

I added another 2gb ddr3 module to 1333 and surprise, it accepted it in the system with the other 2 of 8gb 1866, even if it's different generation, and I see it does not block my system. And although I have 3 slots busy in 4 , in cpu-z reads it as dual, probably asynchronous.

Probably not going to work properly. You need to take a little bit of time and see what the hell is taking up all that memory. 16gb is plenty these days unless you have some really hungry program but it doesn't seem like you do.

 

[LTC8K6]

Intel's Flex Mode will run as much of the ram in Dual Channel mode as it can, when you use different sized modules.

What's annoying is that most desktop and laptop PC's still only come with 8 GB of RAM standard unless you pay more than $1,000 for them.

I'm not looking at the discourse on your memory usage, but am only dropping in at this moment to say "Yes" You can easily upgrade a 2x8 GB memory configuration to a 2x8+2x4 GB = 24GB. But I wouldn't fool around with different makes, models and memory specs.

In my case, I initially had a 2x8 kit of G.SKILL Ripjaws X 1866 with timings 9-10-9-28. The system had an ASUS P8Z68-V Pro-Gen-3 mobo, and an i7-2700K processor -- pretty much the same as your 2600K. I was lucky to find the same model Ripjaws X 1866 with identical timings in a 2x4 kit.

No problem. None at all. I my particular case, I was looking for extra memory to uses with Primo-Cache L1 caching.

Just make sure you test the system memory with all four slots filled. I say -- test it thoroughly -- at least 500% coverage with HCI Memtest. In Windows, watch for BSODs with memory-related stop-codes. It would be an indication that you should probably bump up the VCCIO (IMC) voltage. For the P67 and Z68 boards, I wouldn't let the VCCIO exceed 1.2V. But with a default value of ~ 0.98V to 1.0+V, the stable setting shouldn't need to be much above 1.1V if any adjustment is even required.

but if I added just one module of 8gb to make 3x8 , is ok without problem?probably system will work in 24gb dual asynchronous.

The first 16gb will run in dual channel mode, when 16gb use is exceeded, the other 8gb will run in single channel mode.

 

[topmysteries5]

The first 16gb will run in dual channel mode, when 16gb use is exceeded, the other 8gb will run in single channel mode.

Memory works in interleaving mode. Memory usage will be distributed between number of memory sticks present in system. If total ram usage is 9GB, then 3GB will be used from each stick, not 9GB from first stick / channel.

 

[LTC8K6]

After research, I'm not actually sure how Flex Mode would work in the configuration given, or if it would even apply.

It would work the way I described if he had two different sized chips on the same channel, but he has one channel in dual mode and one channel in single mode.

I know that Flex Mode allows DC operation when you would not normally have DC operation.

The explanations of exactly how Flex Mode achieves this are not very good.

I did the step. What is interesting now, I have memory usage after booting about 13%, before with 16gb I was about 20%. I hope is ok
on the ram it says it would have timing cl 10, the motherboard Is set to 11-11-11 automatically.
