Got me another CPU in this weekend (and another to test yet!).

Opteron 146 CABYE 0540FPAW from TankGuys.biz.

This is my best one yet! I will have to take some screenshots, but this CPU was prime95 stable at 2.8GHz on stock voltage! (1.40V setting on DFI).

10x mult, 140Memory divider (208MHz @ 290)
Thermalright XP-120

2.9GHz Prime95 stable is possible on the 1.40V +4% setting on the DFI (reads 1.42v).
 -

3GHz is Superpi 1M stable, but requires too many volts to be Prime95 stable.
 -

Will be testing its twin today.

Awesome!

Tried running an all-out superpi to see what would happen...

My best is 27.4Sec
 -

At that speed, my RAM was running at 220MHz 2-2-2-5

It would appear that Polygon's extra 35MHz on the memory got him an extra half a second [Wink]

Dumped in my second Opteron 146 CABYE 0540FPAW CPU.

OCCT testing at 2.9GHz, 1.4V +4%.

These two CPU's are only 43 apart in serial numbers, so I would expect them to be VERY similar.

I seem to have two very nice cores now [Smile]

-Plack

Oh, and both of these CPU's are rated at 61C max Tcase. All of my other Opterons have been 55 or under. Possibly the higher the Tcase, the better?

OCCT came out fine:
 -

10x290, 1.4V +4%

That makes two 146's that run at 9x290 1.4v +4% [Smile]

I had been running all day at 10x290 on the 1.4v +4% setting, and for the heck of it, i ramped the speed slightly to 10x295. Held in there for a round of OCCT!

 -

I might try 10x300 on a tad more voltage and see if this core can do it! 2nd one might be a tad stronger.

3GHz is no big deal [Wink]

10x300 1.4v + 10%
 -

Also helps that is is cooler in my house, than was in the conference room.

Letting it prime tonight.

Well, it failed out of Prime95 last night after about a half hour or so.

Backed it off to 10x300 and left it priming this morning. Will see if she is still goin when i get back home.

What speed does your CPU max at on Prime95? Or have you messed with prime much lately?

2.9GHz was easy, but 3.0 might be a tad elusive. I will be checking the progress of mine as soon as i get back. Anticipation is a killer!

I never tried Prime at anything other then 10X300 because I'm getting almost a 20°C rise to 55°C. I now have 2 CPU's with a lousy IHS interface. FX-55 is same thing... But I suspect between 2.8 and 2.9 will be it for Prime..... It's too long a test...

Yeah, thermal interfacing is a big issue with these CPU's it seems. That is why I always attempt to run the lowest possible voltage. With these newer cores, we cant just automatically go to the 1.65 ot 1.75 that you could like on bartons or even 130nm A64's. Little bit of a different game now.

As far as my temps, my house is currently sitting at around 15*C (at least that is what the thermostat says). As you can see from above, the CPU already idles at around 28*C. Thats running an XP-120 and a good 120MM fan. Then full load is at around 45*C. Thats a T-rise of over 30*C under load!

I might be able to handle the 1.4v + 10% at 3GHz during the winter when my room is rather cold, but the Trise will be too much during the summer when it is another 10*C hotter in the room.

BTW, the 2.9 and 2.95GHz runs were in the conference room at work, which is almost 10*C hotter than my room at home. I did the 3.0 and 3.05GHz runs at home. You will notice the difference in temps due to that.

2.9GHz on the +4% setting should be fine regardless of room temp.

Polygon, have you checked the actual Vcore voltage on these DFI boards? Setting 1.4v + 10% should mean 1.54v, but it always reads right at 1.5v. Seems as if the onboard monitor always reads 0.03-0.04v lower than actual. Not a big deal really, since temps are the name of the game. I just assume the temp sensor is correct...

For me, i gotta do long stability tests. Everything i normally run depends on stablity over long periods of time. Long movie encoding runs, long RTS games, etc. So when I say something is stable, its been put through some long testing [Wink] But thats what I myself need for stability, most people do not stress them as hard. Which is why i consistantly have much lower overclocks than everyone else, but i have no problem trusting them to long jobs.

Slightly off subject, but can you do long runs of prime95 on the 275+MHz memory settings? Ignoring the CPU speeds for the runs (like 2.7G's or so). I never could get my ram prime95 stable past 260, but I could pass memtest86 in upwards of 350!

I did a 3-4 hour prime 1 time just recently and I think it was on the Neo4 and I think I did it at at least 300... I'll look for it.... OK, here it is. It's 3 hours at 10X285: here...

I don't have to tell you every brand of memory clocks differently...

BTW, The G.Skill 2X512 of "GH"(UTT) was "only"( [Big Grin] ) $150
