Is MBM good?

K, so I OC'd my Barton 2500+ to 2.5ghz (as much as my bios will allow, 12.5multi) and am fairly satisfied w/ the results. My PC is super-stable (have yet to test it w/ prime95, but will soon) but I am a lil skeptical. I downloaded and setup MBM5 and selected the correct mobo and everything and my temp is idle at like 43C, which I believe is REAL good for sumthin OC'd this much. This makes me wonder if the program is working right, cuz it was only a 5-6 degree increase over stock 1.8. Can anyone vouch for this proggy? Any known problems where it would display incorrect numbers?

Thanks guys, hopefully this will ease my mind, and maybe even Gallstaff's.

yes thats a great progam, its one of the ones i use in fact. i would like to know what mobo your running tho. i have an abit IS7 with my p4 and am runninga 27C case temp and a 35C idle temp and have heard most abit boards will have a 3-5 degree descrepancy more than the actual temp.

the 5-6 degree increase could be because of the added v-core you needed to overclock that thing. im assuming you're around 1.8? because from my understanding the 1.8 was a t-bred core and your new 2500 is a barton core and is actually supposed to run cooler, but like i said its most likely the added vcore. a rule of thumb. if its stable dont worry about it.

it's stable, but I haven't done much with it. I am gunna give it a 24hr test w/ Prime95 this weekend. I am Running an asus a7n8x deluxe. Stock it runs at 1.8. I upped the FSB to 200(400) and the multiplier up to 12.5 (200x12.5=2500=2.5ghz correct?)

This is all on stock cooliong too, which is what was makin me wonder even more. I have an Antec 1000AMG w/ the 2 stock case fans, that's it.

 Dyne Apr 29, 2004
whoa.....getting that and getting it stable at stock cooling? that is VERY suprising. im thinking its going to buckle real quick once you run prime on it. it just HAS to. theres no way stock cooling could be that great for that long. i know p4's overclock well on stock (my 2.6c is at 3.2 with stock) but i also know AMD cooling is the worst you can get. wow, this still suprises me. what speed ram you running with this? i assume your timings are at 1:1?

 Pearl Jammzz Apr 29, 2004
ya, runnin PC3200. so 1:1

 Pearl Jammzz Apr 29, 2004
been running Prime95 for awhile now. It's done 11 (almost 12now) tests and still holdin up strong. My temp. increased to 51, and seems to be stayin there. Case temp is 29 degrees, just incase u wanted to know. I am gunna let Prime95 run through the duration of the night prob.

Thqat was results for the "blend" test. Am doing the one for maximum heat now...Next i'll do the other.

 Pearl Jammzz Apr 29, 2004
Ran the other tests, and was even doin sum other stuff on the PC. for a sec it was at 52, but that's it. Stayed at 50-51 at full load.

 Dyne Apr 29, 2004
the guys at the sharkyextreme boards would be impressed to hear youre doing this on stock cooling.

 gameboy900 Apr 29, 2004
Those are pretty good numbers. Looks like you got lucky and got a good cpu. I can't get mine past the 200x11=2200 speed stably. Although my temps are a bit higher, mainly due to my using a fairly slow speed on the cpu fan and not the greatest case cooling.

A really good test is to get 3DMark2K1 (can't do this with 2K3) set it up to run at max settings and then run the demo mode looped forever. See if your system can handle several hours of that. If it can then everything is running just fine and you can relax.

Athlons are good up to around 85 degrees so basically as long as you can keep it under 70 you're fine. My temps rose only 2 degrees from the stock 2500+ speed to the 3200+ speed I'm at now.

 Pearl Jammzz Apr 29, 2004
I am REAL surpised myself at what it is runnin at. I think the reason it's goin so good is that my room is cool (hottest it EVER gets is like 75...usually around 70) and I have a pretty free-flowin case. I have all my cords moved out of the way as best as I can and I dont have a lot of shit in it. I have a nice cool HDD, floppy, cdrom and my 9700 pro, that's it.

I'll run 3dmark01 and see what it comes up with. Why wont 03 work? wouldn't that push it harder?

That may be true if you don't plan to keep it around for long, but vcore counts. 1.8 with stock cooling isn't a great idea no matter what kind of results he is getting, unless he is prepared to replace it in a year. It's not guaranteed, but it isn't safe. Also, although MBM itself might be solid, that doesn't mean the numbers you are getting are correct. Such a small increase in temperature with the boxed amd cooler? I dunno. I'd get a slightly better cooler for an investment like that. It doesn't have to be copper monster, or cost a fortune, or howl like a banshee. Maybe an Aeroflow or something.

 gameboy900 Apr 30, 2004
3DMark2K3 won't work because in the free version you can't set the benchmark or the demo mode to loop forever.

And yes a CPU will last less time when overclocked...but that's just a risk you run with overclocking in the first place.

 Dyne Apr 30, 2004
everywhere ive read 1.8 vcore is usually the max. anything over that and your asking for it. so you got a 9700 pro as well? sounds like you got yourself a decent little rig. just ordered some kingmax pc3500 (512 stick) ram a couple minutes ago. hoping to get this 2.6c up to 3.2 at least. after that im waiting for the new cards to come out and should be set for a while.

 Pearl Jammzz Apr 30, 2004
ya, I like it . I needed an upgrade from my P3650 w/ 128 ram, haha. Are the temps. in the bios correct? I have rebooted and went into the bios and see similar numbers there.

Not necessarily. OCing at stock voltage (if you can) shouldn't cause any problems. You know they often they just say "we need more 1800+ chips" and set the multiplier. So I'm being picky, but I don't like blanketing overclocking as hurting the life of your chip.

The ramped-up vcore and heat issues are more important when determining how long its going to last. He got one that probably could have been clocked higher stock, like the example I gave above. If he had better cooling, it might be possible to achieve the same overclock at a slightly lower vcore. But again, it all depends on whether or not he has any cash left . He could just run it till it dies and then replace it, as prices plummet and speeds ramp up... I just don't personally like taking that approach.

I finally rebooted my system and looked at what the vcore is at, it's at 1.68. I believe it's what it comes w/ stock. I didn't change it manually but set it to "agressive" settings. Still no probs w/ it. RUnnin solid after bein up for quite a number of days....

See, now THAT'S different. Had I known that, I wouldn't be concerned about temperature readings etc being wrong. Overclocking at stock or near-stock (as I said before) isn't a problem, if your chip is able to do it. Yours probably could have been sold as a 3000+ or something, but they just set them to whatever they need sometimes.

If you were running at 1.8, you'd be causing problems related to heat and CPU lifespan. Particularly because you're using stock (although I'm assuming the copper-core revision) cooling.

 Pearl Jammzz May 5, 2004
Ya, I dun know enuf to mess w/ the vcore. When OC'ing if yer comp. becomes unstable, isn't that usually what they do to try to counter-act it's unstability? Upping the vcore? That in turn makes it run hotter (more juice, of course it'd be hotter) and by pumpin sum more juice and the added heat, it causes your chip to wearout faster correct? Just tryin to make sure I have this all down, .

 Alexvrb May 5, 2004
More or less. Upping the vcore can let people push things further, but it stops becoming effective relatively quickly (after a while you're gaining nothing and just cooking the chip), and yes it does cause the CPU to leak a whole lot more energy in the form of heat. Its affect on the lifespan of the chip depends on the chip, the amount, the cooling, etc.

Mobile Athlons are excellent overclockers since their default vcore is lower than their desktop counterparts, but being based on the same core, they will happily lap up just as much juice as desktop parts. Coupled with the fact that they are unlocked (always? usually?), you can get great speeds out of those. Now that we have more Socket 754/939 boards with working AGP/PCI locks, I'd be interested to see what can be done with both desktop and mobile Athlon 64s, or even the Athlon 64-based Athlon XPs that are going to be released. Whoops, I think I got a bit OT there...

finally got my pc4000 ram. got my 2.6c up to 3.5 stable on stock cooling (with a 1:1 divider). i can live with that 265 fsb
