G.Skill ECO problem and HyperX question

post #1 of 5
Thread Starter 
Hi everyone!

I have AMD Phenom II 955 CPU
GA-890GPA-UD3H motherboard (rev. 1.0 unfortunately)
G.Skill ECO F3-12800CL7D-4GBECO

I bought this memory modules since they were listed in Memory Support List in GIGABYTE website. Apparently, They were designed for Intel P55 chipset and they dont work in stock settings, not even with .15 overvoltage (worked for about 20 hours and then blue screen). Now I set them to 1600MHz but I didnt touch the timings or voltage (9-9-9-24, 1.5) and they work for now. Please help me with what should I do to make them operate at stock settings, I dont want to kill the memory so I didnt set the voltage higher than 1.5. I can raise it without damaging the modules? What do you suggest? I would rather not flashing the BIOS because it is "potentially risky" according to GIGABYTE. If it is necessary I would appreciate if you tell me how to do that.

Now the HyperX. I want to upgrade to 8GB anyway and I thought to add 2 more ECO sticks like mine. Now when I see they dont work so well with AMD, I thought about 2X4GB of HyperX Genesis/blue. whats your suggestion? any other memory sticks that would be better for my system?

I would also appreciate if you tell me how do I check memory stability after overclocking.


Thank you very much!!!

Edit: another blue screen... Im not going to try overclocking my memories anymore. If you can give me a good 1600MHz 8GB memory that will actually work on my system in 1600MHz, It would be great. I dont think Im going to add more of these ECO.

They're designed for P55 chipset, doesn't mean they DON'T work well with AMD. Look at my sig.

Set the timings to 7-8-7-24-40-2T with 1.5V. Slowly lower to 1.35V. For some reasons i.e. RAM vDroop (yes, there is such thing and it affected me on a Gigabyte GA-880GA motherboard on a client PC with ECOs before) you may need to set above 1.35.

May need to raise CPU-NB voltage a few notches for stability. I know I had to (from 1.15 to 1.225) even with the CPU-NB at bone stock.

The highest voltage you should run on ECOs is 1.6V. Not that anything higher will damage them, but usually anything higher is impractical as there's no stability addition.

G.Skill ECO needs 1.4v on AMD platform to run.

Thank you both for your replies.

I know I should set it higher than 1.35V, I tried it on 1.5V and it still did not work. Also, my NB voltage is already pretty high, 1.3V.
I checked in G.Skill forums, there are recommended BIOS settings for AMD users. For now my memories are operating at 1333, cl 8-8-8-24, and 1.5V. this is what I read: http://www.gskill.us/forum/showthread.php?t=7688 according to this, If I will set the FSB to 240, multiplier to 13.5 (I dont have a good enough cooler for overclocking), timings to 7-8-7-24 and 1.5V (for memories) my system should be stable? You think I will need to raise the CPU or the NB voltages?

Thanks!

edit: how you suggest me to check stability? I used MemTest86+ until "pass 1 complete" and there were no errors. I should do better than that?

NB voltage or CPU-NB voltage? There's a difference

The reading on G.Skill forums applies to 1600 CL9 kits. It's also terrible advice, as you need CL7 timings at 1333 to match 1600 CL9 performance. Using a higher bus clock and lower RAM multiplier is actually not a bad option either and it may be a good idea to experience with different RAM multipliers.

Optimally to test OS stability, you should use the HyperPi program set to 32M. memtest86+ is great for finding faulty kits but there are times when a kit unstable in the OS has passed memtest.
