Abit KN8 SLi, Opteron 144 (1.8 GHz), Thermaltake cooler, Corsair TwinX 2GB, Antec True Power 550, EVGA 7800GT (modest OC), Lian Li case, 4- 80mm fans.
Stable ON AIR: 2929 MHz. 325 FSB
SISANDRA: 13159 MIPS - 5943 MFLOPS
Memory Bandwidth: 5025 MB/s - 5050 MB/s
3DMark 2006: 4088
Opty has slight over voltage. Memory is holding me back, I have the voltages quite high and I have relaxed the timings. Opty isn't breaking a sweat. CPU temp is 54c after running 3DMark 2006 with a system temp of 41c. System would boot and run in XP Pro at 2983 MHz, pass CPU tests but flaked out in memory tests. I'm tightening up the memory timings a little at a time at this clock speed and it is helping performance.
Maybe I'll buy that high end DDR just to see how far I can push it. :wink:
All in all, not a bad OC.

Very good Opty results, and nice job with voltages @ 325MHz FSB. Are you using stock cooling? I would assume that's why the temps are that high, but still, great OC! :D

Na, Thermaltake something, can't remember. Don't forget, there are 4 HD's in there as well, DVD burner, DVDROM. Case is closed and in a cubbyhole in my desk. I'm in the process of backing the CPU voltages down, this should cool things off a bit. Optys do OC rather well and I have around $140 in it. :) 

I forgot to add, it idles at 47.5c.

sweet. I was thinking about get a opty 165 I wonder if I could get that high
April 21, 2006 10:11:45 PM

With excellent RAM, it's very possible. I didn't do anything really special with this CPU.
April 21, 2006 11:01:12 PM

No offense, but you must have some pretty crappy ram, because I am my stock speed (2.2ghz) athlon 64 3500+ (newcastle) with 2x512mb corsair xms w/ led @ 2-3-3-6 gives me about 6000mb/s in sandra.
April 21, 2006 11:41:09 PM

No, it's pretty good RAM but not the best out there. Did you not see where I relaxed the settings? No offense taken ;) 
April 21, 2006 11:51:29 PM

You cant usually get the 165 up to 3ghz.,but 2.4- 2.7 isnt uncommon. which is into the fx-60 speeds. the 170 can go hight cause the higher multiplyer.
April 21, 2006 11:56:34 PM

Why I got the 144. It has a 9 multiplier and presented some challenges. Just get a MB that is known for having high FSB that actually work.

He is most likely not running @ 1:1 on the memory due to the 144 only haveing a 9 multi.

Those 144 offer a good bang-per-buck. TankGuys had them boxed for $129 (3 year warrenty).
April 22, 2006 12:53:19 AM

I am running 1:1 and may try 2:1 for giggles. I was adding the cost of the Thermaltake HSF. :)  I now have CPU voltages reduced and now light loading at 41.5c. I have also tightened the memory settings, will re-run benchmarks soon and post update.

That does make sense, I didn't really notice that the opteron only has a 9x multiplier with 1:1 fsb. You can't set the fsb to 4:5 on your board? I was able to take my Pentium 4 515 2.93ghz up to 3.52ghz on air and stock voltage, with the memory at 4:5 it kept up just fine, and I also have the TwinX on that machine. I could probably go higher but i haven't tried, the performance gain won't do much since I just use that machine for music downloads 8) .

I know, I'm a noob at overclocking, so I probably dont' make much sense. I would like to see some benchmarks also though, maybe it would be worth it for me to get an opteron to replace my newcastle 3500+ with.
April 22, 2006 6:04:20 AM

It makes sense but using the 1:1 is yielding the best results. On another MB, the 4x worked better, go figure.
I have sense tweaked the RAM, reran SiSandra. I got 6131MB/s - 6134MB/s.
I may order some high end RAM and try again. I actually achieved 3119.6 MHz but wouldn/t pass the mem test, so that was a no-go. I could surf the net, play winamp, etc though.
April 22, 2006 2:25:44 PM

Ok now your RAM sounds like it's working properly, what settings did you tweak? Maybe you had it on 2t command or 3 CAS ?
April 22, 2006 2:48:19 PM

Yes, I had it set on 2T. Once the OC was stable, I started tightening the RAM settings. It's rock solid now, I'm even playing FEAR on it. I'd love to get better RAM and try for that 3.1 GHz.

Madmodmike, it really helps to read the post, before you reply to it. Especially when your quoting it in your own post. rofl.
Hey man, I think those temps are waaay too high, you need to clock that baby down before you burn it up, or get a better cooler.
April 22, 2006 3:19:37 PM

I personally don't think 43c (109.4 degrees) is hot at all for a CPU with over a 1 GHz overclock. After tweaking everything, I started lowering voltages, this is now where the temps are.

Nice, 43C isn't bad at all. Well done on your overclock!
April 23, 2006 10:28:01 PM

Thanks but I'm not done. I am now stable at 3010 MHz @335. This Opty keeps on going. SiSandra: 13504 MIPS - 6104 MFLOPS, Memory is: 6880 Mb/s. It keeps getting better. :)  Needless to say, it's exceeded my expectations.

Just noticed I forgot to post the 3Dmark2006 score. 4231
