[SOLVED] Hey are these ram sticks compatible ?

[ayeooo444]

As title says are these compatible with an asus z87-k right now i have 2 4gb sticks and one 1 gb stick installed. 4 slots total. Mmoment 8GB DDR3 1600MHz UDIMM PC3-12800 1.5V CL11 Non- ECC Unbuffered 240-pin (2Rx8 / Dual Rank Base on 512Mx8) PC Computer Desktop Memory Upgrade Module at Amazon.comother stick. 8GB 2Rx4 PC3-10600R (DDR3-1333) ECC REG SERVER MEMORY | eBay Very much appreciated.

The Non-ECC RAM the 1600Mhz is compatible but the ECC one is not accourgin to section "1.4 System memory" of your motherboard's manual here.

Are you planning on adding the new RAM stick to the already mix and match setup?

Your system, if you are in fact using two 4GB sticks plus one 1GB stick at the same time, is not working in dual channel mode (which is better than single channel). If you add a 4th 8GB there's a chance the system won't boot because of all the different RAMs (in terms of size and speed etc.) or that it will auto clockdown all memory to match the speed/clock of the slower stick/module.

So basically right now im running 2 4 gb sticks and 2 1 gb sticks and i bought 2 4 gb 1600 mhz crucial sticks off ebay and i took both my 1 gb stiks and slotted those and my pc wouldnt boot i ended up returning them cuz i thought they mightve been broken or something i have no idea why they didnt work. If i buy the 1600 mhz stick of amazon it should 100% work? Im a cheapo and on a super budget so im looking for the cheapest ram possible so suggestions on cheap ram would be appreciated.

Also if i have 2 4 gb sticks then 1 8 gb stick will it run in dual channel mode?

As I said before the one you returned didn't work most probably because of mixing and matching RAM. They might have been OK to use on their own, but not alongside other RAM of different specs.

No two 4GB and one 8GB won't run in dual channel. You have to refer to the manufacturer documentation (the manual) and see what it says. Sometimes boards the two matching sticks would work in dual channel and the 3rd stick in single.

According to your board manual:
"You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation".

So if you're lucky the two 4GB would work in dual channel and the 8GB in single mode because all are 1600Mhz (although timings and other factors might be different a bit). There's no gurantee when you're mixing RAM.

You said you're on a bughet but I would sell the two 4GB and forget the single 8GB (from Amazon) and I'd buy two 8GB from a kit (matching pair already matched by the manufacturer, guranteed to work together as it should). Then you'd have 16GB working memory.

i just bought the 8 gb stick and ima hope that ram i have still runs in dual channel because it would cost me double the amount just to run in dual channel mode for a slight performance increase which i dont think is worth for me.

Let's hope it all works out. Good luck!

And is there a way to see if my ram is running in dual channel mode?

You can download the portable version of HWinFO (no installation needed) from here or a copy of CPU-Z. When you run them in Windows it shows in what mode (single/dual) the RAM is running.

Actually it says its running dual channel right now while running 2 4 gb sticks and 2 1 gb sticks. Imgur: The magic of the Internet So if that works im assuming i should be good to go with the new ram i orered. Also that says dram frequency 667 mhs that means my ram is running at that lmao? when it should be at 1600 mhz.

Beacues they are an even number =4 and are working in pairs. If you run two 4GB and one 8GB that'd be 3 and the 8Gb won't have a pair to run in dual mode with.

And again. There's not gurantee when mixing RAM that did not come as a kit. Even two sticks like the one from Amazon (same brand, capacity, timings etc.) came out of the factory same day which are identical, right? One might work with your current setup of 2-4GB and one might not work.

The 2 1 gb sticks arent the same brand or the same anything i pulled them out of a 15 year old pc but ur saying it works bcuz all 4 slots are filled?

No they're working in dual channel because they're in pairs. Two 4GBs and two 1GBs. The fact that they're working toegether with mismatched RAM is just lucky. Not because all 4 slots are populated.

Im trying to do research on my motherboard but i cant seem to find any info if it supports x2 4 gb sticks and x1 8 gb sticks for dual channel. i hope my motherboard supports that.

anyways thanks for ur input just got a radeon 5500 xt for $200 great deal in my eyes now upgrading my power supply and gonna top my pc at 16gb nice upgrade for me coming from a gtx 750 haha

As I mentioned before quoting the manufacturer (motherboard's manual) the two 4GBs would work in dual channel (the pair together) and the 8GB in single channel mode. If the sticks being mismatched doesn't cause any problems.

No problem. I hope everything goes OK and you enjoy the system upgrade.

Hey sorry to bug you but would this work with my motherboard? Also, wouldnt it just be overall better because i can then run everything in dual channel mode. Hynix HMT451U6BFR8C-PB 8GB 2 x 4GB PC3-12800U DDR3 1600 CL11 Desktop Memory Kit at Amazon.com

Again, as I said few times above, there's no gurantee. You are mixing RAM. Yes your motherboard is supposed to run 1600Mhz RAM without any overcloking to the CPU and the RAM but I can't say for sure this pair would run with your other pair or not work/boot at all. There's a chance they don't work together like the other pair you had to return.

It says PC3-12800U and that U stands for unbuffered and according to your motherboard's manual you need non-ECC and un-buffered memory. This is unbuffered and non-ECC (otherwise they'd state ECC on Amazon) and in theory would work with your motherboard and CPU. And yes IF they work they'd work in dual channel because they are a pair.
