I have a couple quick questions I hope you guys can help me out with.

1) How many people are running a 146 Opty on Phase (and what clocks)
2) Is anyone having problems running 1:1 with TCCD

Right now I am at default volts (1.36v) under phase at 1:1 at 3.1ghz 32m and prime stable. I am trying to see if I can take my ram and clocks a little higher but was looking for some ideas where to improve.

I found that my opty likes Max Async at 8ns and Read Preamble at 5ns. Has anyone else run into this? Also TRRD at 3. I have never run into this before. Thanks!

Will do tomorrow after work...

Cabge are not the best clockers, 2.7-2.8ghz in general it seems. My 146 Cabge won't go much higher than 2.7.

got my CABYE from monarch.

verified tonight max 2906Mhz on my evga free motherboard at 1.62v
and this baby is about 3-4C cooler than my San diego at 2.75Ghz with same voltage same maxTcase.

currently running 324x9 on my 146 on 1.55v. It's a CABYE 0536. MaxTCase says it's 59c, and it hits 56c every once in a while during prime. Oh well :P

Voltage/Clock/Heat characteristics vary quite a bit. Which stepping/week did you get? 0536 CABYE seems to taking over 1.6v without nearly as much heat. Unfortunately maybe not as much OC either. Eva2000 took his 0536 CABYE to 3.03ghz with 1.65v 32M stable.

That's pretty good, I would try 1.6 with the side panel off just to see if u can hit 3 gigs stable. So.. now that u got that, my cpu will be shipped out tomorrow right? ;)

Yeah....about that...I didn't plan on waiting so long to ship it (seriously, I didn't). I meant to ship it monday but I haven't been home (DBZ marathons @ friend's houses own me way too hard.)

ANYWAYS, I tightened my BT QUITE a bit more and It's not hitting over 52c now. 1.65v? On air? I'm a little worried to do that...but I ran 2.95ghz in 3dmarks on 1.55v with NO issues at all, I guess an extra 50mhz could be done with a tad more volts.

What are optimal ram timming for opteron ?

That was my first run on this mobo and I haven't started tweaking yet.
4x512 sticks of Uber crap ram thus timings are kept low so as not to be an issue.

This is the exact same stepping as mine and it rocks... got it 3200 mhz 32M stable (look at previos posts around page 68 i think)

Is that on air pt1t?

I'm thinking about ordering a s939 opteron 148. The steppings available are:

cabye 0536 gpmw
cabye 0535 xpmw

Which one should I get?? Have anybody here had good experience with any of these steppings, espeically on single stage?

Air on the DDR :D (new BH5 chips)

Wc for CPU , but WC VS Good air for short benchmark is +- the same when room temp isnt too high.

Hey.

Since often better steppings have had later vocabulary letters in the stepping I would chous the later one..

Another question, its stepping related also, 146 cabge 0536 vpmw, does cabge suck always or could you frankly be lucky?

Thanks!!

When I finnish a run I always press print screen first, then I boot up clockgen to lower the clocks to a stable level and then I'll open paint for some ctrl-v action :)

Try Xpmw..they was good before, but i have not seen screens on them with opteron yet. cabye is not the best it do about 3.0ghz with 1.7v(Air,most of users use air).
(Pm me where you can buy them)

And new steppings are fun to test :)

Are you saying I wont go especially higher than 3.0Ghz with a LightSpeed???

I would not try 0536 vpmw...this is a 144 ->
MonsterProzi 0536 VPMW yes Lukü Prime 2661 Mhz @ 1,55v

ehh my Cabye is 32M stable at 3150 mhz at 1,69 on water...

hey whoever asked. yea it seems that i have probs running 1:1 with my 146 as well.... up to when i was within range. after that the 183 and 166 dividers gave me probs so i been using 150 and 133 since then.

testing my 146 from computersmsa, and it isn't the better, but not too bad

full aircooled box moded 24v :D

Got my CABNE 148:

Did a whole day benchmarking 2900 GHz on stock volts (which seems to be 1.4 Volts).

Water is always water maybe the most make 3.0ghz 1.65v on air and 1.7v 3.1ghz+- on water

Ordered from Compumusic when they were giving out the exact markings of this chips they have in stock.

Packaging for shipping was major suckage, though, the green inlay to hold the HSF and CPU was totally crushed, at first I though the CPU is missing :)

Forgot to say the 2.9 GHz stock voltage are with a Big Typhoon, AS Ceramique and my DFI SLI-DR.
