I'm trying to test if my memory is stable and found that hci is good for stability. How do I use it though? I have 16 gb of ram.

Never heard of hci, but Memtest86+ is very highly recommended as well as easy to use.

Download the .iso, burn it to a CD, set your BIOS to boot off of the CD drive. Itll do everything automatically from there.

I did use that and no errors were found. Just making sure my overclocked ram doesn't affect my CPU overclock.

What do you mean? You just did it? Its only been 10 minutes, unless you mean you did it in the past some time. Let memtest run for a few hours, through multiple passes.

Yeah I did it lets say about 2-3 hours on 2000 9 9 9 24 2t 1.5v. Which is weird right? No errors during that time.

Memtest 86+ is primarily used for seeing if you have bad sticks. If you want to test a RAM OC try programs like hyper pi and MaxxMEM2. You can also try out Prime95 and IBT/LINX, but the other two are more memory intensive.

Did you ever try running it for a long time instead?

If you don't know how to use it properly, you probably didn't use it right. Assuming you're using the free version, you need to open one instance of the program for every CPU core you have. Then take your available RAM (or 90% of all RAM), divide that by the number of CPU cores, and enter that number in each instance of HCI memtest. Let that run up to 1000%, if that produces no errors move on to another program (or just call it a day if you just need basic stability for gaming).

Maxxmem as a stability test? I've found that if I can boot into windows, I can run Maxxmem with no issues even if I get errors the second I hit start on any other program. Hyperpi is good for initial testing, but I'd still do a long P95 run after Hyperpi has finished because 10-15 minutes of stressing the memory isn't particularly thorough.

Maxxmem as a quick speed test. Overclocking RAM and timings can be extremely time consuming. Would you run Prime95 for 4 hours after lowering TRc one digit from stock? No,you tweak with maxxmem to get highest stable speed and lowest timings,then run your Prime/memtest or whatever and adjust from there.

I usually can tell if RAM is somewhat stable just by the way Maxxmem runs. If you are close to the edge of benching stability,it will bug or hang-up,or your scores will drop. Another good one to use is SiSoft's Sandra bandwidth and latency tests.

HCI Memtest is actually quite good for stressing RAM.

200% passes for initial stability, 1000% passes for complete stability. Has never failed me even once.

Usage: Open a HCI Memtest for every core/thread your CPU has and assign your free ram divided by the amount of CPU cores to every individual HCI.

This way the RAM will be filled up 10)% and tested fully and it'll go nice and fast since all threads can work on it. HCI is single threaded so using all RAM on 1 HCI is slow as hell.

Nha, I use Hyperpi 32M for quick testing. I've never seen Maxxmem have issues with an overclock, even if it turns out to be unstable as hell when I use any other program, so although I do run it every time I've tweaked something, I never even considered it as anything but a speed test.

Not only that, but it's limited to around 2-4 GB per instance of the program, so it wouldn't do much good any way.

HCI picks up errors much quicker than memtest 86. Simply divide amount of available ram by no. of cores and let each core share the work load after running 32m super pi to test for initial stability is the way I do it
