AMD Phenom II X4 980 will not run stable over 4gb

you may have also found the limits of a motherboard and chipset that wasn't the topnotch overclocker as well. its not just the cpu that's at play.

That's a pretty good overclock on air. Can you post up more cpu-z shots of your overclocked settings? And what are your ambient temps like?

[ulao]

My room stays at 78, I know its high, my wife likes to save Plus the case is sort of boxed in. I do have air flow but not as much as an avid clocker would like. It may go higher with more voltage but that is going to be hard to cool with my setup I'd think.

[moosteve]

the ram is underclocked. you need to set the divider to 1:4. or is that by choice?

[zila1]

Yup, your ram speed is low, are you mixing ram?

[ulao]

No its the same make ram, but It was suggest earlier in the thread to under clock it? So confused...

1) get those ram timings back down to spec. 1333 @ 9-9-9-24 @ 1.5v
Right now there overclocked (running 1600 ) but loose as a goose.

[DrGuns4Hands]

not sure what kind of ram you have but wanna shoot for 1333 at the lowest timings that'll run I'm using OCZ reaper at 1333 6-6-6-18 1t, AMD likes 'em tight

You misunderstood me. I never said underclock it, I said get it back down to spec so you could tighten the timings.

[moosteve]

he has mismatched ram. one is a 1333 and one is a 1600.

Good eye.
I'd run those at 1333 at the tightest timings they could stand.
EDIT- I'd like to know how he's getting dual channel with 1 2 gig stick and 1 4 gig stick.

[zila1]

I'm confused, cpu-z is showing he's running 12288MB??

[DrGuns4Hands]

Apparently he found the cheat code for super ram boost.

[Mr.Scott]

I see whats going on now. The 1600 kit is an 8 gig kit. The model number gives it away. That means the 1333 kit is a 4 gig kit, total of 12 gig in dual channel. Now we know why he's having such a hard time on the overclock. Mixed ram, 4 slots filled. Much tougher on the IMC.

[ulao]

Should I remove the 4 kit? I dont think I need 12 gig. Then once I do that how do I get to spec? I know my mobo has some advanced mem tweaks, just dont know much about it. What should I look for in cpuz or whats closer to ideal.

Ok I dropped the 4 gig kit and I'm at 7,8,9,9 do I want to hit 7,9,9,9 if so how?

Additional Comment:

OMG did that just make things run faster!

[Mr.Scott]

I'd try 7-8-7-24 @ 1.65v @ 1600

In my bois I can see where to bump on the volts but Under Dram Timing Mode setting both DCT0 and DCT1, I get a long list.

I see: TCL, TRCD, TRP, tRTP, TRAS, TRC, tWR, TRRD, tRWTTO, tWRRD, tWTR, tWRWR, tRDRD, tRFC0, tRFC1, tRFC2, tRFC3, TCL, TRCD, TRP, tRTP, TRAS, TRC, tRW, TRRD, tWTR, tRFC0, tRFC1, tRFC2, tRFC3.

Ah I got it now.

So your suggestion is
7-8-7-24
TCL-TRCD-TRP-TRAS ( no need for command rate? )

i would leave the command rate on 2 for now... not the biggest of deals speed wise between 1 and 2, but if it can't handle 1, it will really trip up your stability.

This. ^^^^^ 1 adjustment at a time.

[ulao]

well I adjusted the timing and set the "over voltage" to 1.65. The text when from white to yellow ( guessing warning ) the system tried to restart but failed. System was no post. So I reset the bios and tried with out the higher voltage. System this time restarted but still would not post.

Suggestions?

[Mr.Scott]

8-8-8-20 @ 1.5v @ 1600
