looks like 8GB is the problem, removed all but 1 stick and OCCT and Prime95 are ok so far(10 mins).
This means I need more NB volts yes? Anand article said they had to use NB volts at 1.52. Guess I'll try that next.

More pll, try 1.54, 1.56, more nb, try 1.52, vtt 1.32 1.34 Load line enabled. Dont throw in the towel so fast trigger, your voltages are way to low, you have a quad and 8 gigs of memory, is going to take more voltage to get that stable, try my settings, if is unstable add 200 mch, and +20 nb gtl, and call me in the morning. What voltage is your ram rated for ? probally need more ram voltage to.
On both my Striker II's, I don't need that much NB voltage for this configuration. In fact, I found it a bit unstable when I raised the NB to 1.50+ volts. Try 1.44-1.48 (that's with the over-volt figure into it.)
Increasing the PLL to 1.52-1.54 is a good move.
Edit: I've also found that by setting the vtt to 1.28, over-volts to around 1.31. If your board doesn't over-volt as much as mine, try setting vtt so it hovers around there.
This is with my new board.
Why is it when I set CPU volts to 1.3 with LLC enabled Everest is saying 1.42
I took 2 sticks out and ran 4GB, it runs at 1800 L+S no problem. Testing the other 2 sticks now, thinking maybe I have one bad stick?
Edit: Scratch that theory the other 2 sticks run L+S at 1800 aswell.
They just won't all run together. Trying some more settings.
Your voltage is off because the board overvolts from what the bios says, you can always lower the cpu voltage later. You need to test your ram first make sure all sticks are good, i use memtest in windows, i dont like memtest 86. Im almost positive a just a setting in the bios, and you should be fine, i wouldnt waste my time on 1780 , i would go right for where you want to be, cause then your going to have to through all this again, cause the settings will be totally different, just link it at 2000 bro, and go from there, set the timings on your ram loose, and get the cpu stable first, then play with the ram timings.
Hey Sangrak, how can you be linked and synced if your ram is running at 2000, but your fsb is 1780 ? sorry that aint linked, you need 2000 ram, and fsb, which is 500fsb, or its a typo.
Linked and synced 2000FSB with this cpu = 4.5ghz. would not post.
I tried unlinked 1800 cpu and 2000 fsb, lost a lot of mem bandwidth in memtestx86 and Vista crashed before I could even run a test.
I used the 9-9-9-24 SLI-EPP setting the bios gives you when you turn enable the SLI-mem setting but still NFG at 8GB. I should have tried it while I had only 2 sticks in. I'll do that later right now I'm back to try to get 8GB stable at 1800 L+S.
You dont have a 8x multi ? how is it 4.5 ??? 8x500 is 4.0, you must have a 8x multi. Please dont use the sli enable memory, that garbage.
Have you tried more nb voltage ? where you at now with nb ? cause 1.4s aint going to crack it, it takes me 1.56 to hold my 2040 mghz, my gues is you need at least 1.54, that could be the problem with why 4 gigs goes but 8 dont, you have watercooling right ? im on air at 1.56, and fine, up the nb, cause i know if i drop to 1.54, wont run at all, i get dram error on lcd poster.
Try auto on nb gtl, if is unstable, try adding +10 +20 +30, im using +20 for my setup, and dont be afraid to try up to 1.58 nb, just to see if that gets your 8 gigs of ram going. You have to understand, thats alot of ram, very straining on the nb, is going to take some volts to get it stable.
So your fine with 4 gigs ? it works ok ? but when you go 8 trouble ? i think 1.52 should be ok, did you try nb gtl ?, what about mch ?, you should post a template of your current settings, would be alot easier to try to help. Do u have any MCP Reference voltage ?
But same setting not working for you. Im talking about the mcp voltage, 200,201.5 etc, you may need some of that. Dont know what to say, same setup, and it dont work for you, varies between boards i guess. Well if he has it stable, then you can get it stable, always more work with a quad.

Montana have you tried more vtt ? 1.32 1.34 ? How much ram u using ? 2 gig 4 gig ?
Thats because this board has a serious overvolt problem, i enable llc. So then your unlinked, to me its way harder to overclock this board unlinked, linked and synced is much easier at least for me.
