Got my s939 X2 3800+ at 2.6ghz

[Oyeve]

I havent OC'ed since the Celeron 300a days as I have never really had a need to. But, recently my s939 X2 3800+ hasnt been cutting it since R6:Las Vegas, so last night I mucked around my mobos setting and got my CPU up to 2.6ghz (2ghz is stock) and my idle temps are 40c and loaded is around 49-51c. I got this on stock voltage using my ZALMAN CNPS7700-ALCU HSF. How much more can this cpu go? Its the Manchester core. I think 2.6 is pretty damn good.

Pretty damn good is an overestimation, its probably average. 2.8 would be pretty darn good, 3 would be top notch. But your using a manchester core, and all I know about is the toledo cores. I think manchester is supposed to be better then toledo though.

And you could add some vcore, I'd go to mid/high 50's in load temps, then stop.

Toledos are WAY better, and 2.6 is great for a Manny.

As a comparison, 2.6 would suck for a Toledo, but it's great for a Manny.

2.6 is pretty good. I have a manchester core in my 3800 x2 as well and can manage 2.7 w/1.5v, but the temps get outa control which causes Prime/Orthos to fail miserably. Currently I'm sitting at 2.5ghz with stock voltage under a Zalman 9500 stable as hell. As of now my temps are 34-35c idle, 48-ish load. It's warm in my house though, so if I were to open a window it would cool down (I've seen as low as 26c idle in the winter >)

By the way, Toledo cores typically have the 1mb l2 cache and are used in Opty's whereas the Manchester has the 512k l2 cache and are used in the X2's. Toledo's have been showing up in the X2 line with half the cache disabled though, so if you've ordered recently this may be the case.

I had mine running at 2.6, but had to lower it to 2.5 as it kept locking up at 2.6.

Mine is @ 2.3ghz and I think the ECS mobo is the bottle neck.

 

[MarcVenice]

Ok so I was mistaken and toledo's > manchesters. Then you should be happy with 2.6ghz at stock vcore settings It's not at auto, right, but set at 1.35v or so, right?

 

[GeezerMan]

Yep, 1.35 is peachy. I think the specs call for 1.30 to 1.35. I set up a Toledo 3800+ X2 at 2.6GHz, 1.35. It will easily do more, but temps rise too much. I like to overclock and keep things at stock volts myself.

 

[hydroponik]

2.6-3.0 depending on the stepping. Google your stepping and see what others are getting.

 

[ArchAngel777]

Depends on the voltage... But from what I have seen from the thread in Hot Deals, most of our CPUs can get 2.6Ghz, and some of them hit 2.8Ghz. You will likely not see anything better than 2.8Ghz

Lately experienced way too many freezes in game graphics.
Reducing the 7900GTO to default clock speed didn't help.
Bringing the cpu to its default 2.0ghz the games are now running just fine.
What'd happened?

The rig ran Prime95, Memtest for 12-24hrs at 2.3ghz w/o any errors.
CPU temps: 37c idle, 41c load
GPU temps: 47c idle, lo 50c-hi 60c depending on games.
Go figure!

Try lowering the CPU multiplier to 8 or so, and keep the FSB at 230 ( you were at 230?) . That well tell you if the board is unstable at that FSB. What's the ram divider at?

You don't want your HT link to be to be much over 1000 ( 5 X 200 FSB is stock), so you may have to lower the FSB multiplier from the stock setting of 5.

 

[lopri]

Yup. Toledo > Manchester, and San Diego > Venice. To this date this remains a mystery to me because it's against the common sense. (less cache = less heat = better OC, no?)

 

[Zenoth]

Heh, my 4400+ Toledo is an abysmal lemon when it comes to over-clocking, or it's perhaps my Memory that is abysmal ... or both. I cannot get past 2.42Ghz / 220 FBS anyhow.

 

[Smoove910]

loosening your ram timings and adjusting your divider might help you achieve a higher overclock.

 

[Zenoth]

I tried, and it failed, all the time. It's just a very bad over-clocker.

So is mine.
I agreed.

my 939 x2 3800+ will get to 2.6ghz. I've posted as high at 2.9, and booted @ 2.8. My cooler is not the best, and I like to leave c'n'q on to reduce the power draw and temperatures when I'm not doing much. My mobo just pooped its pants, and it going back to ASUS for repair, and upon return I plan to lap my hsf and the ihs. Hopefully this will lead to lower temps, and I can achieve the 2.6 oc @ stock voltage (c'n'q kicks it up to 1.492-1.55v).

 

[GeezerMan]

Maybe I'm misreading your post, but Cool and quiet will only take the CPU volts as high as you have set it in the bios.

 

[Comdrpopnfresh]

I set it to 1.35, yet when c'n'q is enabled for some reason it just sets is to what I believe is unnecessarily high.

Something wrong there. It should never go higher than what you set it manually in the bios. Lower , yes, when it throttles down, but not higher.

 

[Comdrpopnfresh]

well as soon as you turn it on, the divider and voltage sections are greyed out. I guess its one of those "supposed to" things, kinda like how I'm supposed to be able to set qfan2 to a target temperature. something wrong there too

 

[Smartazz]

I think that's pretty good for stock voltage. I have to put up 1.425 volts to hit 2.6GHZ on my Windsor core.

 

[Oyeve]

Well, BIOS bitched this morn, I had gotten it to 2.8 for the last 24hrs, then Bitchin BIOS reset it down to 2, gonna try tonight to maintain 2.8 with a mild volt boost.
