  1. Yes, but this thread is about overclocking the Opteron 165, not a best-of-3dmark thread. You need to understand that some of us see overclocking in itself as a sport, a challenge. If you get 1-2fps extra in Doom3 isn't particularly important (none of us would actually notice the difference) in this particular case, and 3dmark-scores isn't interesting here. If I overclocked my 165 to 4Ghz I would still not beat your 3dmark score with a X1900XT.. see my drift?
  2. 2.4 stock volts isn't bad at all. Try voltage @ 1.4v-1.425v and see if you can hit 2.5-2.6.
  3. I feel there's a need to tell people that those "recommended steppings" doesn't mean YOUR chip with one of those steppings will overclock at all. It's a statistical recommendation, not proof that every CPU of a certain stepping is guaranteed to reach a certain speed. Some steppings (CCBBE 0610xxxx) have a higher number of quality chips than steppings CCBWE 0609UPMW (or whatever) where the average number of high clock cores are severely diminished. When they sell these chips, unless it's specifically stated that they've been pre-tested, you may end up with a dud or a star. Getting a CPU from a known good stepping is just a way to raise chances of getting a good one.
  4. SuperPi (using 1M test) Sisoft Sandra (for various purposes) PCMark 2004/2005 3dmark06 is good to measure dualcore performance (when looking at CPU Score). The stuff Onixman recommended is pure gaming stuff. That MS advisor won't really tell you anything.. The most important task benchmarking is doing is let yourself compare performance between different settings. That's the main reason for benchmarking as far as I'm concerned. Comparing to other systems is just secondary.
  5. Nice OC dude. My core #0 doesn't like heat, it fails @ ~50C when stressed if I go over current speed where it's rock stable. A tip for people not owning Dualcore CPU's yet: The chance of finding a dualcore chip where BOTH cores hit 2.9-3.0Ghz without problems isn't too big. You may have one core that goes past 3Ghz while the other keeps you @ 2.5. Luck of the draw, even when it comes to known steppings.
  6. You're overclocking the memory controller which may be a reason for extra sensitivity in timings and settings.
  7. One simple question, if you use 1.4v on the CPU, does the board run a higher FSB? (with HTT Multi 3x)? With 1.00v on the CPU it's a wonder you can even reach 2Ghz.
  8. What's wrong with the CCBBE's? They're apparently the current sweethearts of the Opty family..
  9. Actually, until AM2 have matured and there's actually stuff for it that is BETTER than s939 (as opposed to slower like the current trend is pointing towards) I wouldn't worry about the AM2 platform. I can't see it going anywhere until late this fall/winter or even next year. Until then, 939 is still king. But I know what it means to be stuck when putting together a new system. With all the buzz around the Conroe, AM2, DDR vs DDR2 I would feel all confused and indecisive as well. Thankfully I've got my Opteron 165 which I am very happy with. I'd never trade it for a standard Athlon64/X2. It's cheaper yet most of them are performing better than their little brothers for the desktop.
  10. Seems like someone is going to learn about safe and good O/C'ing the bitter way...
  11. wow, those are some sweet temps. however, you're currently clocking low on your cpu so you're not really pushing it at all. and as for the lifespan, it may vary but I doubt you'll be there to see the CPU fail because of overclocking. I've never had a CPU die on me for overclocking and/or overvolting (relative to default), but I change CPU's (and mobo etc.) every 6-18 months. If you drop the lifespan from 10 to 5 years, ask yourself if you're still going to run your Opteron overclocked in 5+ years time. By the time it fails Opterons are worthy of a museum.
  12. Just picked this up. Apparently AMD is planning on released the 5000+ and FX62 for the s939 platform as well. AMD hasn't spread the word though since it would put a stain on their current AM2-campaign. proof: http://www.amd.com/us-en/Processors/Produc...ml?redir=CPT301 As you see in the list, the mentioned CPU's are listed as: Athlon 64 X2 5000+ (socket AM2 and 939) $696 Athlon 64 FX-62 (socket AM2 and 939) $1,031
  13. Don't overclock both RAM and CPU at the same time while you're looking for the sweet spot...
  14. Don't use other peoples "combos", each system is unique. Even if you have two systems built with the same parts down to the coolers, one is most likely easier to overclock than the other, so forget all that. 1. Find the sweetspot of the CPU FIRST.. keep the RAM below it's default level. 2. When you've found the CPU's sweetspot you can start to look for the RAM sweetspot. Make sure you keep CPU slightly below the sweetspot. 3. Read the guides and threads over and over again, get acquainted with the BIOS.
  15. I wish people didn't try to overclock everything at once picking random speeds they want to achieve. That way they're chasing their own tails since they can't tell if it's the RAM, the CPU or whatever that is causing problems. *sigh*
  16. Don't try to find the best overclock on your CPU and RAM simultaneously, you'll just have a big mess to sort out. Drop the speed of RAM to half of what it normally is, then concentrate on finding the max CPU. Just going for some random values messing around in BIOS without focusing on one thing at a time will just make everything take 5000% more time.
  17. Go for a better heatsink/fan. You'll just regret it when you notice you need better cooling a few weeks down the road. All current Athlon64's and Opterons have IHS on them whether OEM or retail. The Opteron 170 have a 10x multiplier as well (but it's understandably more expensive than the 146 & 165).
  18. I can't see why anybody would buy X2's instead of Opterons when it comes to dualcore. The X2's are more expensive, more difficult to find good chips (since the good chips usually go to the Opteron line due to tougher requirements of stability for the workstation/server market). Check out www.xtremesystems.com and you'll see that most overclockers use Opterons, not retail X2's. When it comes to single core, that may be a different matter. The same still goes for the 14x's though, they've got higher requirements and usually overclock better than their X2 counterpart (while being cheaper). AMD knows this but they don't really care since the main bulk of CPU's are sold through OEM's or to average jane & joe that knows nothing about overclocking and wouldn't dream of believing Opterons were actually usable on desktops.
  19. It may be as simple as you having got a bum chip. Just because you have the same stepping as your friend that got 2.7Ghz doesn't mean your chip will, and since the stepping list @ xtreme says "CCBWE 0550UPMW (Some are crappy actually)" about your stepping, you may have to accept that you'll have to live with a 400-500Mhz O/C. Not sure how you've gone about finding a stable O/C. Did you do the CPU-seek first (ie. drop RAM to a low divider like 133 and the LDT to 3.0x to leave the RAM out of the equation) and start from scratch, increasing to 2.0Ghz, dualprime, raise another 100Mhz etc. and then in jumps of 50Mhz when you hit 2.2Ghz? That's the way to find the sweet spot for your particular chip, go slowly from the bottom until you reach the max, then raise voltage a notch or two and see if you can take it further. It seems to me you've just been trying random speeds. By trying to simultaneously O/C'ing the RAM you won't know which part is causing failure. Start over from the beginning, use a low divider on RAM and try to find the max of your particular CPU. That's my recommendation.
  20. There's no point in running LDT @ 1.40V since it's not being overclocked (or shouldn't).
  21. Thanks for the list. I can however report that my Aspire ATX-AS520W 12V has been working flawlessly since I got it with rock stable voltages. Perhaps mine is a fluke then?
  22. Hmm.. I have no solution, just a memory of this happening on DFI's nf2 & nf3 boards as well, onboard NIC's just dropping out. One fix was to re-set the MAC for the NIC, but that shouldn't be necessary.
  23. Do you really need that amount of voltage to get the CPU to 2.5Ghz??? Personally I'd never go past 1.55V. Seeing as the default is 1.35V, a 0.2V overvolting is quite a bit. Since your temps are ok you're apparently not at risk for burning up but I still thing 1.68V is way past the limit of 24/7 usage. What happens when you try to dual-prime the setup @ 1.5V?
