Well guys, I finally got the nerve to OC my system some. And it booted up at 3GHz first time. I have yet to run any stress tests though- but I think I'll hold off on doing that for now, check my "idle" temps:

Yup, with only a few light background services running (Steam, lightscribe, Sidebar, Everest, etc) it hovers in the low to mid 50s- and that is well too hot for my liking.

So, I'm gonna' drop it down to about 2.8 and see how she be. :D Though I'm curious, what voltage would you gusy recommend I use for 2.8? Right now I'm at 1.425- could I bring it down to maybe 1.00 and still have enough juice?

3GHz? You would had done that 2 years ago.

Try 4GHz. :afro2:

Cool, Redeemed. That's the CPU I'm lookin' at to get in the very near future.

This baby does rock. Xion was bragging up a storm about how awesome Opterons are (on s939 anyways)- and he wasn't lying! :lol:

I was almost expecting "problems"- but nope- notta'. :D

Anyhow, here's some more pics at 2.8GHz:

Anyhow, she is running a bit warm- so I just decided to invest in two of these (http://www.newegg.com/Product/Product.aspx?Item=N82E16835191008) for her.

I'm contemplating getting the CoolIT Eliminator for this rig as well... but since I've heard so many mixed reviews I'm undecided. Anyhow, these two fans should help out a bit. Right now I have no exhaust- only intake fans (on my case)- so I'm expecting these to lower temps atleast a little. :D

Pretty cool too that you have 4x1GB DIMM and did not have to resort to T2 and 333MHz memory clock :)

Yeah, I'm hoping for some good results when I get my 185 as well. I ran my 170 at 2.6GHz, so hopefully that 3GHz isn't out of the question for the 185. ;)

Yup, the s939 opty's were great. My opty 175 was greaaaat. I loved it. Alas it was a bit slow for my liking....quad core FTW!!

As far as voltage is concerned....I would run it as low as you can while being stable. So once you determine if you're stable at the current voltage, start dropping it one increment at a time and test stability again. It's hard to say how low you'd be able to get it...definately not 1.00V like you said in your post....maybe 1.40? What is stock voltage on that chip? 1.35V? In the end it all depends on the chip. Oh and I'd use ORTHOS to test for stability. If it runs for 30 min then you're good to lower the voltage. Once it fails, bump it back up a notch and test for a couple hours.

Yeah, I was worried that having 4GB of RAM might cause some issues- I recall people complaining about it a while back. So far no problems. :D Again, haven't done any stress testing yet- but I did leave my rig running overnight and it never crashed or nothing. :p

Anyhow, when I get in from work tonight I plan on testing it with Prime95 for a bit. If it doesn't crash while doing that then... on for some gaming, probably a bit of STALKER. :D

Opteron S939 FTW!!!11 I miss my old 170 @ 2.93GHz...too bad it just couldn't keep up. I remember when I first got it, had one of the best steppings at the time, I almost died :D

Mind if I ask which steppings are supposedly the best?

And even at stock, there really isn't anything this chip wont bulldoze right through. It's no Core2, no Quadcore either- but I haven't found anything that it just can't do yet. :D

Anyhow, any word on which steppings are better? Is my Opty one of the better steppings?

Idk much about opteron 185 steppings, but I would assume so if 3GHz is stable. Maybe check out this (http://www.overclock.net/amd-cpus/128767-socket-939-opteron-most-overclockable-stepping.html) thread :). My 170 was a CCB1E 0550VPMW. Unfortunately, there's not much specific info on 185s due to their high price a while back, most people chose the cheaper 170s and 165s. Now that the 185's price has dropped considerably, the interest isn't there.

How bout running superPI 1M in 13 seconds? :D or even better, 4 instances of superPI 1M in 13 seconds :D Bet you can't do that :p

I just managed 14 seconds with a bunch of crap running in the background. Not too bad I guess. :p

Last time I ran it was on my Athlon 64 3000+ running at 2.5Ghz. I think I got something like 36 seconds. Its not even a dual core benchmark. :lol:

Hmm... how do I find the stepping for my CPU? The one CPU-z lists look like nothing listed on that forum.

lol- and why would I care about that? I'm a gamer, and there really isn't any game this rig can't mull through on "High" settings, if not the highest settings- depending on the game. ;)

lowest I ever hit was 11.46 for the 1M :p But that was with a 3.8GHz E6600

AFAIK, the only way is to physically look at markings on your chip. I think the steppings on AMD cpus are more more complex then intel's? Which is maybe why you can't simply look for a "G0" or "B3" equivalent in CPUz.

I wouldn't bother taking your 185 out just to find a string of numbers, especially since you've already oc'ed to 3GHz. It's more of useful piece of information to know prior to testing, gives you a general idea of how far you can realistically hope to push it.

:(

I actually tried forcing it down to 1.00 in BIOS- setting doesn't seem to stick. It seems as though it is cemented in at 1.425. Anybody have any ideas how I could change the vcore? Is there some other setting I'm over looking maybe?
Redeemed
11-25-07, 03:01 PM
Well, I dropped the voltage down to 1.325 and it actually stuck... sort of. CPU-z shows it as being 1.36v but still a fair bit lower than what it was before. As such my temps are now about 5*C lower. :D

Whats up with those temps? I overclocked my friends opty 175 to 3ghz and using the stock cooler he is idling at 32c and loading at 55c under prime 95 for 8hrs. I also didnt have to raise his voltage any at all, he has a great chip!


The only way to find out how much vcore you will need for any given overclock is to stress test your CPU with Prime 95 using SMALL FFT's. REMEMBER, SMALL FFT'S.

Dont just overclock without stress testing, its not a good idea and could lead to a corrupted OS.

I don't know why nor how, but for some reason my vcore got stuck at 1.425. Even at "stock" settings, it was still running at 1.425. Hence why my temps have been so high all along. Well, while tinkering with BIOS settings the other night, I tried dropping the vcore by .1 volts. It sorta stuck. In the BIOS it is set to 1.325, but CPU-z reports 1.36v. I might try dropping it a bit lower. Haven't done any realy stress testing other than Oblivion last night. Which was *really* wierd. I haven't played the game in a while, and since the last time I had played it I have updated my drivers and dl'd some new hotfixes for Vista... but at 1680x1050, 4xAA, 16xAF, GCAA, TMSAA, and all in-game options maxed I was never getting below 45fps- ANYWHERE!!! Now not too long ago we had a huge thread comparing the 8800s to the 2900 and Oblivion was the main game used... in that thread even GTX owners didn't fare so well... so I'm thinking that the newer drivers and hotfixes might have done something to aide in my incredible FPS boost- also I might not have been in really stressful areas, though before while outdoors my FPS would drop to the 30s or a bit lower sometimes. And now, same settings, never below 45fps I bull**** you not. :D

Yeah, I'm happy. :D

Though my rig is doing something wierd... in HL2 I got to the part where you're in the buggy and that gunship is chasing you. You jump that fallen bridge and get to the part where the road is cluttered with old cars and you have to get out of the buggy and shoot the gunship down with your rocket launcher. Before my computer literally blew through that section at 60fps+. Now for some reason, as soon as I got out of my buggy my fps tanked and I'm getting 1-3fps at best. I've even tried disabling all unnecessary services, lowering the graphics settings, restarting- everything *but* undoing my OC. I find it hard to believe that my OC has anything to do with this as Oblivion is playing better than it ever has, and that puts far more stress on my rig than HL2 ever could. Anybody have any ideas?
