Copmpleatly unstable memory. Help!

post #1 of 9
Thread Starter 
Hi, pls help me to adjust my ram settings. In all default it's ok, but I'm running my CPU at 3.6GHz, FSB 249MHz. (CPU is stable 24/7) Before 2 days I've buy a new memory (A-Data Premier 4GB kit (2x2GB) 800MHz CL6 + Arctic RC) recommended voltage is 1.8V ± 0.1V. In normal mode my MB is set the voltage to 1.920V. I'm trying to run at FSB 249MHz x3.33 = 830MHz, timings 5-5-5-15

FSB : DRAM is 3:5
tRC 21
CR 2T

I don't know much about the ram, but I know that with CR 2T is more stable than the 1T, and In AMD systems is better to lower the timings than higher frequency.

When I put timing to auto mode they are 6-5-5-15

and how the NB can help here? Max multiplayer is x10 there. In the moment is in Auto mode(2241 MHz). also I'm trying to keep HT Link close to 2GHz (in the moment is 2241MHz)

Anything beyond what's rated on the sticks is a gamble..

ok I have put timings from auto to manual (6-6-6-18-25 2T), and put NB Frequency to maximum (2490 MHz). Like that for now it looks stable. In auto mode it was (6-5-5-15-21) and NB was 2241 MHz. What I can change to stabilized it on lower timings, and which of them I must change, and which I must not touch. Also what is the "safe" voltage for my ram (cooled by Arctic RC)

P.S. sry for my english.

Is 6-6-6-18 the stock rating? If so, that's probably what you needed. 6-6-6 at 800 is pretty sad and generic though

Yes, 6-6-6-18 is stock. I will keep it around 800 MHz, but I will try lower timings. Can you tell me how I can make it stable at lower timings - only DRAN voltage or...? And what voltage max I can put? Stock is 1.8V ± 0.1V, my MB automaticly set it to 1.920V. I have Arctic RC on it... The memory is A-Data Premier 800 PC2-6400 2x2GB kit

Heatspreaders would not be worth it at all on generic memory. Unless you can at least manage a slight OC on the RAM, you would've wasted your money. You may want to push the voltage more... with heatspreaders like that, I don't know what you couldn't do.

ok I have set timings at 4-6-5-15, NB-2490 MHz

4-6-5-15? That's actually starting to approach decent. Can you mange 4-5-5-15?

I can load Windows with 4-5-5-15, but when I try ti run SuperPI it's give me error. And I don't see more performace...

4-6-5-15 || Read-8GB/s; Write-8.8GB/s; Copy-9.6GB/s; Latency-49.9 ns
4-5-5-15 || Read-8GB/s; Write-8.8GB/s; Copy-9.5GB/s; Latency-50.2 ns

I saw that when I first try to overclock it at more speed. in 880 MHz was better than 900 MHz, and at 920 MHz was like at 880 MHz. Now it's at 830 MHz, because I read somewhere that for AMD platforms is better to lower the timings then high speed, and for intel is better to get high speed...something like that
