Well, that was interesting. First pair, no problem. Second pair, no post. I removed one stick and it booted right up. I'm guessing I got a bad stick. I continued with the test as per your instructions and all columns (for the three sticks that work) are the same.

Now if you'll excuse me, I think I need to contact Corsair about this stick.

btw, I looked for a way to add "SOLVED" to the thread title, but didn't see how. Also, I ran the MemTest86+ while I went to dinner. No issues with the three sticks.

1. Pair off your two 8GB(2x4GB) Kits by consecutive s/n's
2. Plug one kit in and using CPU-z look at the SPD tab. Take a screenshot of BOTH sticks SPD in CPU-z by selecting each stick individually using the dropdown box in the upper left corner of the program.
3. Swap that pair out for the remaining pair, do the same two screenshots of SPD tabs of these two sticks
4. Now, compare the columns and rows of the four SPD tabs you have now.

They should be identical. They MUST be identical. Any difference(s) that might exist is very well your issue.

---

Let me know what you observe in the above. We then might proceed to using MemTest86+.

Nope. Didn't know something like this even existed. I'll give them a try at my next break between holiday parties! Thanks.

Update: I had a talk with a veteran gamer/pc builder who was able to dumb things down to my level. I realized that more RAM doesn't mean more voltage. Subsequently, I tried a couple lower settings, 1.5 and 1.375, but still no post.

Things are not going well in Kwaggie's mire. I tried all frequencies from 1333 to 2133 (with the CPU NB at 1.625 and 1.2375) and all CPU NB voltages between the default 1.1625 and 1.2625 (I know, but I had to try). I'm currently running three sticks at 1333 with the CPU NB at 1.1625. I haven't touched anything else since resetting the CMOS. I'm not sure what to do next, so unless there's another suggestion, I'll have to go with this (still six times what my old machine was, RAM wise). Would it be worth the time to try each frequency with each voltage (stopping at 1.25, I promise)?

fyi, I was wondering how I could have missed the CPU NB setting before until I realized I had to switch the Multiplier / Voltage Change to Manual in order for it to display.

ROFL never believe what you see on youtube unless it is from a verified source. 1.4v on the northbridge is crazy high. As you saw, Wardog recommended a maximum of 1.25v and that even that is a little high though at least within the realms where the cooling on the board can handle it. You came out of it ok tho so not a problem Wink Live and learn.

Wardog and PetrolHead both know their AMD kit so I will leave you in their capable hands.

I guess you can't believe everything you see on YouTube (2:29).

PetrolHead's link to the AMD FX Performance Tuning Guide is still very relevant. It's quirky and convoluted in places while reading but once you wrap your head around what all it espouses and then understand the quirkiness you'll have graduated from Noob Status :)

Assuming the problem is not related to the sticks themselves, you should be able to boot with four sticks at 1333 MHz. If they're single rank, then 1600 MHz should work as well. If not, even 1600 MHz is an overclock and may not work without extra voltage. You may also need to increase RAM voltage to achieve stability.

Some more reading (pages 15 and 19 at least):

http://www.amd.com/Documents/AMD_FX_Performance_Tuning_Guide.pdf

Btw, don't change the NB voltage, change the CPU/NB voltage. These are two different things (see the tuning guide for details). Leave the NB at its stock voltage 1.10V. The CPU/NB stock voltage is 1.15V and that's the one you want to increase if need be. Just keep an eye on those CPU temps, since the CPU/NB (the memory controller) is located on the die itself.
