As the title suggests, I'm having trouble deciding which pair of ram modules to install to go along with my current pair.

My current RAM - Adata XPG V2, 8GB (2 x 4GB), DDR3 1866

I've only seen it on Newegg, which has run out of stock. Would it be possible to install a pair of DDR3 1600 modules from Adata? Or would my best bet be to wait until the 1866 is in stock again?

Here's a pic of my current ram from Speccy:

This is the ram I have in mind: http://goo.gl/AR9jm2

Thanks for any and all help!

First change the RAM sockets as Slot #1 and #2 for the old RAM, #3 and #4 for the new RAM, Because MB checks them in order.


Try setting the timing 1866Mhz 10 11 10 30 1.5V manually. If it didn't work,

Try loosing the timing on XMP 1866. Set it to 1866MHz 11 11 11 30 1.5V
If that didn't work,
Try setting both RAMs to 1600MHz 11 11 11 30 with 1.5V.

So it might not be able to run at the optimum speed, but you'll be able to find the best settings following the above method.

@Tradesman1: So mixing DRAMs doesn't usually go over very well? Even when using two of the same set (#6 in your link) isn't 100% guaranteed to work? But it's pretty likely, right? As long as that's the case, I'd rather spend around $50 then $100. Gotta keep saving for college, y'know? If Nuwan Fernando's suggestion doesn't work out, I'll go with yours. Thanks for the advice!

Nuwan Fernando: I did as you suggested and went to change the settings in the BIOS. These are the only things to have changed - http://postimg.org/image/4dgmnkuf3/ As for the RAM, thanks for the suggestion, but my ocd won't let me get any ram that looks different then the set I currently have :( But as I thought, it's not guaranteed to work with what I have.. So I'll probably wait a bit to see if the 1866 gets back in stock before trying these. Thanks again!

Edit: Ha, just kidding. My available virtual memory jumped up to 13 GB. Or would that be due to the difference in RAM uasge? (62% usage in first pic, 31% in second).

@tea urchin: Looks like this is what I'll be doing. Well, until I get tired of waiting, at least. Thanks for the help!

I've gotten matching sets right from the manufacturer that wouldn't play, in fact in another article I did

http://www.tomshardware.com/reviews/dram-benchmark-fluctuations,4080.html

Two manufacturers sent two pair of 2 sticks as they didn't have a 32GB 2400 set. With both brands, their two sets didn't play until I made some slight voltage adjustments. Other sets I've seen wouldn't play regardless of voltage and/or timing adjustments (and I've been working heavily with DRAM for years (including secondary and tertiary timings). It's basically a crapshoot.

If you try mixing and have problems, give a shout and we can try some voltage/timing adjustments

Alright fellas, I'm back, and with brand new RAM!

I just got another pair of the A-DATA XPG V2 4gb 1866 ram modules. I installed them and... Well, I'm running into a bit of an issue.

tl;dr - Computer works with XMP settings @ 1333MHz, but not 1866MHz

After first installing them and turning on my computer, it failed to boot. So I booted with optimized defaults and it worked fine. I went into the BIOS to see what changed, and it reset what Nuwan Fernando had me do - changing the XMP to get the RAM from 1333MHz to 1866MHz, amongst other things. I redid Nuwan's solution to make sure that was indeed the issue, and sure enough, the computer failed to boot.

Taking a look at Speccy, it looks like there are a few variations in the tRAC and tRC settings, the frequency, and JEDEC numbers. Here are some screenies.

Slot #1 and #2 are my new sticks of RAM, and have the exact same numbers.
Slot #3 and #4 are my old sticks of RAM, and have the exact same numbers.

If it helps at all, my mobo is GA-970A-D3P.

I tried all the settings for 1866 and got nowhere. Decided to try going for 1600MHz, and it worked. My computer is currently running with my RAM set at 1600MHz with no issues. Well, aside from the two BSoDs I got due to CPUZ. I believe the error was "PAGE_FAULT_IN_NONPAGED_AREA (cpuz136_x64.sys)". I uninstalled the program. Hopefully that'll be the end of any issues with this new change in RAM settings.

I had sent a support ticket in to ADATA's customer support. Apparently, my Motherboard doesn't support ADATA's ram at 1866. It'll support Corsair, G.Skill, and Kingston... But not ADATA, as shown on the QVL - http://s24.postimg.org/amqe42539/image002.png

Thinking I should just give up on 1866MHz. Anyhow, thanks for all the help you've given me! If you have any more suggestions I'll gladly give them a try.
