Aaron's Big Ll64 Upgrade

[wtf8269]

Stock 2-3-2-6.

I've read reviews and although I may not be able to run these timings exactly, I should be able to get something close to what these people did:

1.5-3-2-6 @ 217 2.6v

1.5-3-2-6 @ 221 2.8v

2-3-2-6 @ 225 2.6v

2.5-3-2-6 @ 250 2.8v

They're rated for 216MHz, so they should do better than 200, odd... Try switching the slots they are in, I have seen that work many times on DFI's. Play with the command rate/timings too, then tweak them later. And another thing, bios will probably be a little buggy, don't expect miracles.

I wouldn't worry too much on overclocking ram just yet, see what you can get out of just the cpu, then do the ram.

Yeah, I did some reading on DFI street and I'll figure it out eventually. There's about 30 settings for RAM and it's just going to take awhile to learn them all or get the hang of it. I'm just going to stick with 2.8ghz and PC3200 2-3-2-6 1t for now.

Did somebody say benchies?

Card is stock for now, can't find anything that will OC it. Although ATI Tool will detect temps and control the fan which is nice.

Well 2.8ghz was unstable. Right now I'm running 2.69ghz with ram at 192mhz 2-2-2-5. I still really have no idea what I'm doing with ram though. I'm sure if I knew what I was doing I could get this RAM way over 200mhz and the CPU would be at 3ghz or even higher.

 

[djbbenn]

Awesome... ATITool beta 9 will overclock the X1800 series. Give the opteron some more juice to get it stable.

Alright, did some more reading on DFI-Street and got some better RAM settings to dial in that helped me a whole lot with overclocking. I was able to boot to windows at 3.2ghz, but it was unstable. I'm currently running a 32m Super PI test at 3.1ghz, but I'm running a 1/2 RAM divider so I'm just finding the max CPU clock right now. Next comes the max RAM clock then hopefully a good mix of the two.

Edit: Well as of now I'm running 3ghz 1.63v (300x10), 3x htt, RAM is at 2:3 so 200mhz 2-3-3-8 stable so far. I'm going to post my exact bios settings on DFI-Street in order to get help perfecting my RAM timings and the whole overclock in general. I think it's time I start installing some games now though.

 

[djbbenn]

So the extra voltage helped? Most Opterons I seen at 3GHz+ were at ~1.6V.

-Dan

 

[wtf8269]

No, I've had it around 1.6v the whole time. These RAM settings are what did the trick for me:

Drive Strength - 3
Data Drive Strength - 1
Max Async Latency - 9
Read Pre-amble - 6.5

 

[djbbenn]

In you screenie it said 1.45V???

-Dan

 

[wtf8269]

Yeah it's either because of my mobo being so new, my CPU being so new, or a combination of the two. Anyway got some freaking awesome RAM settings from a friend. I haven't done extensive stress testing but the clocks in my sig I think are probably where I'm going to stay at after working on this all day. I could probably get some tighter timings on the RAM, but that'll be another day.

Edit: Meh back to stock, turns out the timings my friend gave me don't work so well on my motherboard. So it's back to stock for now.

Looks a bit like my X Dreamer II.. except its 10x better quality ^^; Is that case quiet? with all those fans.. this freaking X dreamer II only has 2 fans.. and it drowns out my music.

Edit: BTW amazingly SICK rig.
