AWESOME DUDE!!!! I GOT THE SAME STEPPING!!! I got a Zalman CNPS-9500, and a DFI SLI-DR Expert.

EDIT: waiting for MOBO to arrive before I OC.

Best signature ever, even my girlfriend laughed!

Thats very impressive. Does the "stepping" (whatever that is) matter when it comes to overclocking? I have an Opteron 165 myself and with CPU-Z it says the stepping is 2 just like yours..in fact everything is the same (Toledo..etc). I haven't tried overclocking yet but will in a couple of weeks once I clean out my case wires, put in another fan..etc.

Try benching it in 3D. I don't know why people keep doing P95, when we know that often the limitations come from the memory controller and 3D content.

The "stepping" can't be seen through software. Pop off your heatsink and gently remove the thermal grease using 91% rubbing alcohol- DO NOT USE ANYTHING ELSE! This will take off the grease and evaporate very quickly so it won't cause any damage. On the chip itself, look for this line:

CCBWE 05** **MW

The first number, 05** (0550 in my case) is the year followed by the week of production. This chip is year 2005 week 50 so 0550. The next letters **MW also have a lot to do with the overclock. When it is all said and done an overclock is about 75% stepping and 25% luck.

If you hapen to have a dual core opteron and you'd like to PM me with this line, I can tell you quite a bit about your chip and provide an estimation of your potential overclock!

CAUTION: DO NOT attempt to overclock if you don't have a good power supply, unstable rails will cause the electrical current to fluctuate. If it goes lower, you'll crash. If it goes higher, you may fry your chip. You always risk frying your components when you overclock- but a sturdy PSU is a must!

Noted! I'm doing some cpu burn in overnight tonight and I'll run PCMark05/3DMark05 tomorrow.

VERY nice overclock. how many fans/what brand did you use??

Right now I'm using the stock fans in the NZXT Lexa classic case with the exception of an 80mm fan I have mounted over the PWMIC. I have the case laying on its back with the door off, I have a bunch of fans and detailing stuff on the way so I'm going to wait until they arrive because I don't trust the stock fans.

The big typhoon with a careful application of Arctic Silver 5 using a plastic bag (Search the "Cases and Cooling" forum for a tutorial I wrote!) and a razor to even it out smoothly is all you need, assuming you have good intake and exhausts in your case. Good air cooling will allow you to take your chip to just around 1.6V (IF you want to risk it) without having a heat problem.

excellent o/c.

just out of curiosity, what exactly is superpi 32M stable? is it just using superpi and getting to 32M? i have never used superpi as a measurement of stability, just benching and comparing.

Yes, using SuperPi 32M is the standard test for CPU stability at XtremeSystems. Prime95 (or SP2004- same thing) for 8-24 is a stronger test of stability.

that is cool, i am suprised that superpi would be used for stability since it will probably only take ~30mins with the o/ced opterons. i always used prime/looped 3dmark personally.

what the heck is this Opty scene all about??? WOW!!! all i hear is good news about the Opterons!!! can't wait to get my AMD system up!

Cheers!

AMD price changes today supposedly. Optys will no longer win the cost vs performance debate if the pricing rumors hold true. It'll swing back to the X2s as the preferred OCing chip for many if it does.

I strongly urge you to try S&M. My CPU @ 2.6ghz/default voltage can do dual prime for 10+ hours (still running now, trying to go for 20hrs) and finish SuperPI 32m. S&M can't even pass on my default speed and core voltage (1.8ghz) :(

Nice system! Anyways, I'm 25% done S&M. What are you using for a heatsink? Are you using arctic silver 5? I'd suggest installing an 80mm fan directly to the right of your heatsink in the PWMIC area, as this was getting *HOT*! Try that and see what it does for your stability, just a thought.

S&M makes my PC cry :(

My PSU always fails the test :(

It's almost overly stressful, since it will find instability that no other program will.

Really? With a modstream 520w? I have one of those here too- but right now PowerStream 600W is chewing this test up and spitting it out. :cool:

EDIT: Started getting pretty hot, waiting for my fans on Wednesday!

Dual SuperPi 32M Stable! @ 1.53v

Opteron 165 0550 UPMW
DFI Ultra-D Revision AD0
Thermaltake Big Typhoon

I have $70-$75 worth of fans, wire management and lights on the way from two stores, both due in on Wednesday. Pictures coming soon after!

Specifications in signature!

Update: 30 minutes in to dual prime, so far so good!


When and from who did you get your CPU??? I'm in the market and if you just got it, I'd like to take a shot on getting the same stepping.
