Opteron 1xx Week 0551 Chime in!

[Doctorweir]

So my Opteron 165 CCBWE 0551UPMW is finally up and running.
Did not do too much tweaking yet, just threw it in and went for it...
Currently I am stable at 2655 (295 HT) with 1.425 Volts.
At 1.45v and 2712 (Asus definition of 300HT :roll: ) Core #0 craps out after 15 Minutes of Prime. Clearly a heat issue, as it goes up to 57C when running fully loaded for a while. If I do not Prime Core #1 in parallel (aka it runs cooler) it lasts me longer.
I am quite confident to get this baby considerably higher, because
1) I only applied some AS5 to the IHS as I plan on removing it anyway (just wanted to sort out the RMA necessity before... )
2) I did not set the Radiator fan to full speed yet (only 1500rpm) however, I want to keep the silence...
3) My FSB-limit is 315 and still far away...

Other experiences with recent Opterons?

Update 2/2/06:
So I removed the IHS as planned to give this baby lower temps and max out the rather cheap waterblock of the TT Bigwater.
Removing it with my trusty taped razorblade exposed the usual dried up AMD paste: Pic
Man, that core is huge...but good for the heatsink contact...
I rather like it clean
Then I threw "real" thermal paste on it, double layers of fabric tape on two sides to prevent canting the waterblock and back in the rig...
Result: 5C less and Dual-Prime stable @ 2700 (300x9) @ 1.475v
Still goes into the 50s, but totally stable. When I get a better waterblock this baby may have more potential. But for now I'm a happy camper and wait for the AS5 to settle and give me another 2C less...

this is watercooled and you're seeing 57C? Crazy man. Highest temp I see on my X2 watercooled was 40C and that was dual Prime with 1.63 volts. Of course, i did have the IHS off, so you will definitely see gains when you do that. Temps are your main restriction. A note though - radiator fan speed shouldn't affect your CPU temps by more than 1-2 degrees, and if it does then your watercooling is severely underpowered.

57C is definitely too much, but it is the fully heated / warmed up max...idle is about 36 (coming down from full heat again).
In addition the watercooling is just a cheap setup, so I do not expect wonders, hehe But more silent than the 7700Cu and more stable temps.
Speaking from experience the IHS removal will give me ~8C plus "thoroughly" applied AS5 even more... This should bring me back into the 40s.

My 4200+ @1.475v, 2.618ghz runs at 51c with the stock heatsink, so there is really something wrong if you are hitting 57c on water..even my overclocked pentium-D isn't hitting those temps on water..

Well, you never know how accurate those probe-tools are => Using AsusProbe II

Bump for update (see OP)

Old thread bump I know, but when you remove the heatspreader, I assume that you then leave it off when attaching the heatsink?

I'm looking at getting an X2 over the summer, and I'm thinking of removing the heatspreader already. I did it for a K6-3+ proc already, as well as some others in the K6 line, and they all survived just fine. I've also removed the shim from a Radeon 9700 Pro, which uses the same delicate organic packaging as the X2 appears to use. It too survived with no damage.

Sure, IHS stays off and heatsink is to be carefully applied...just take care with the capacitors when razoring it off...someone here razored the capacitor also and so this experiment got expensive...
