Check your Dram Drive strength, Dram Data Drive Strength and Tref. For me, those are the big three. I can't pass test 2,3 & 5 when I use a "bad" tref, regardless of how much voltage. I've also noticed that when using the wrong tref, increasing the voltage on these sticks gives me more errors.Originally Posted by jcniest5
With Dram Drive strength set to 5,6 & 7 I'm stable at 250 with 3.2v and i can set Data Drive Strength to 1,2 or 3. At 260 Mhz 3.5v only Drive Strength 5 with Data Drive Strength set to 2 or 3 will work. Dram Drive Strength set to 6 & 7 would also work but I need more voltage (3.6v) at that the same FSB to be stable.
Tref. I've played with all sorts of settings here and i've found one of the best ways to find your ideal settings for Tref and Drive Strength is find timings that give you just a few errors (around 10-20) at whatever frequency in test 5. Yes thats right, for once in you should be happy to see errors in memtest.
Now start playing with Dram Drive strength, Data Drive Strength and Tref - one at a time. I'd start with Dram Drive strength then Data Drive Strength and finally Tref. If you finally find a good combination of Data Drive Strength and Dram Drive Strength and you're able to get rid of the errors in memtest 5 with those settings, note them down (you might end up with several good combinations) and then change back to settings that would give you 10-20 errors again.
Now try and find the most stable tref, you might find several once again, note all of them down.
Once you can pass without errors increase the frequency again and work with only the trefs and Drive Strength combinations you found. You'll be able to narrow everything down to just a few settings.
My working settings:
Tref = 2560, 3120 and 3684
Dram Drive strength = 5 & 6 Depending on FSB, 5 is the most stable at higher FSB
Data Drive Strength = 2 & 3 at 255+ FSB with Dram Drive strength @ 5
With the GH i'm able to throw very tight timings at them and they'll be pretty happy, if i get Tref or Drive Strengths wrong I ran into all sorts of problems and no amount of voltage seems to help then.
Hope this helps.
Here's a screenie of 1.5-2-2-0 @ 260Mhz with AGGRESSIVE timings, I shed off 2 secs in SuperPi and everest read jumped from 7100 to 7400 from my previous 260Mhz settings. Now, if only i could get my winchester stable at 260 x 11 i'd b well happyi've topped out at @ 2750mhz (250 x 11) prime stable
