Overclocking an Opteron 144

post #1 of 9
Thread Starter 
So my RAM's limit is 180mhz, and now I'm onto my Opty 144.

I have it at 315mhz, with 1.665 Vcore, and it seems to be stable(I've been running prime for a few minutes). The only thing is, my temps hit the low 50s when I run prime.

So a few questions:

Should I sacrifice speed so I can lower voltage/temps?

Is this normal with a Big Typhoon and Arctic Silver 5 on? Or did I put too much paste on? Its been running since this Wednesday, so shouldn't the AS5 have cured by now?

Thanks

AS5 takes about 200HR (load) to fully cure, 1.665 vcore sounds about right to have a 50c+ load, what are your memory timings?

3-4-4-8, but memory isn't in the picture yet, just overclocking the CPU.

Okay, I added my RAM into the picture. I lowered my CPU to 310mhz so I could keep my RAM at its limit(180mhz) by using a 9/10 ratio. I also was able to lower the vcore to about 1.550, and the load temp is about 46.

It appears to be prime stable, but I'll run it overnight to see. I also just ran Aquamark3 for fun...HOLY $#%^. Wow, my scores skyrocketed. From a 56k to 80k. I think it also has to do with me lowering my GPU OC, because it was throttling before, but both scores went up 3000. Geez!

I'm hoping this is stable, I'll Prime tonight.

Nono, I have the memory, I just had it on a 1/2 ratio so I was just testing the limits of the CPU. It's on a 9/10 ratio now running at 279mhz while the CPU is at 310mhz.

I seem to be stable now at 2790.

Any suggestions on how to improve? I suspect my temps should drop a few degrees when my AS5 cures(it's been on for about 5 days now).

Dont keep referring to your memory speed as 180, thats the divider. Looks like you are stable up to 280 with your memory, very nice....
If I were you I would just run 2.7 for your daily clock. You aren't going to get much more performance unless you tighten the timings on your memory...but you gotta test different settings...

If i had that chip, I would run it with these numbers:

300x9
HTTx3
Vcore (whatever is lowest and stable)
Divider 180.

You are looking good, but is it really worth giving it that much voltage for 70mhz? You should only use those high voltages when you want to benchmark, your games wont make that much of a difference with 100mhz.

Oh yea, post a link to where you bought your Gskill memory, or on newegg...I want to read up on it.

Referring to my memory as 180mhz is actually a recurring typo, apologies.

Also, the memory timings are rated at 3-4-4-8, so they're not going to go any lower than that, especially past DDR500, what they're rated at.

I bought the memory on newegg, but I bought the 1gb stick, rather than the 2x1gb set, because I didn't have the money, but I plan on buying the second stick later.
