View Full Version : Celeron 800 @ 1080 (8*135)

All those recent posts about the Celeron 800 made me feel greedy! So after running at a mild 896Mhz (112FSB) for a few weeks I started tweaking again, and to my own suprise I'm now at 135Mhz FSB with 1.85Vc and 3.6Vio. It's been running for about 3 hours now with Seti running permanently, I burned a CD, did some surfin', ran Photoshop a few times. Sheesh! I've been at 1032 for weeks before, but after I got a new 256MB stick of ram I couldn't get to that speed any more. Can it be that I 'burned in' my RAM?! LOL! I'll let you all know if it really stays stable!

Here are some specs...
Looks good, nice temps and Vcore is just about right (1.84)

ok today after running win2k (Seti) and my usual tasks for 32 hours without a crash, I rebooted into Win98se for a try of 3Dmark2000. The demo locked up after a minute, bumped the Vcore to 1.9; locked up after a few loops. Set the AGP speed to 1x, ran for two hours until I needed the PC myself Heehee! Seems I'm actually 'stuck' at 135Mhz FSB

Still using a generic sloket?
thats pretty good but what you mentioned about burning in the ram, had you tryed it at 3.6v vio before?

The fairytale has ended today! This morning I found win2k had locked up running Seti overnight. System locked up during bootup after this so I upped the Vio to 3.7V and everything seemed fine. When I got home from work the system again locked up during the NT bootloader or/and when the system went into GUI mode. So I was like WTF?! I really don't wanna upp any voltages anymore. So I went back to 112Mhz. With this mild OC I'm running with CL2-2-2, 2xAGP and at default voltages. (the BE6-II defaults to 3.5Vio) Maybe with another (official 133Mhz capable) mobo I can get this Celeron 800 100% stable. But right now I really don't wanna risk frying half my current setup, just to get close to 1100Mhz at all costs! I have been around 1Ghz before, but I found the system to be very unstable when the PCI and IDE are underclocked. What can we all learn from this? Don't stare yourself blind at the 1Ghz limit!!!
Lancelot,
Ok, 112 is rock stable, and you've been to 135 and it was not.
How about in between? 125 gets you 1 GHz, how stable was "very unstable"? Every FSB setting around there was unstable? Or did you blow past that setting reaching for max?? My curiosity is piqued suddenly by all the claims of 133 FSB+ with these chips.....
I still don't buy 150 FSB with one (1.2 GHz), though, but I'm wondering now... if my P/// 600E will get to 159 FSB, why couldn't a C800E hit 150? That would still have to be a one in a million chip though.
If these consistanly reach 133 FSB, this throws a lot of the old thinking out the window.....

Yeah I know Mr.B, I haven't been lying about all this! I tried to tell you all before that this chip seems to be very willingly. These must be EB chips discarded for a bad cache, and remarked as a Celeron 800. Mine runs around 133Mhz (boots up at 140) and without any extreme voltages so I dunno. All my efforts so far have been made on a iBX mobo (thus not an official 133FSB chipset) and with a generic slocket. Another weird thing is that if I take out the 64MB PC100 stick, with the single 256MB PC133 stick I cannot even get to 125Mhz! So I really think it's the mobo holding me back, not the CPU. 256MB is also the max. DIMM-size supported by the BE6-II. Maybe I'll get me an Asus CUSL2 late summer and see what happens...
Is it really worth going to all this expenditure just for a small performance increase. I only ever recomend the celeron to some one with a bx board who want a cheap simple upgrade, but if your going to be footing the bill of a new board as well then you would have been much better off going for a duron setup

Yes, and indeed I am in doubt. The thing is I still have my old mendocino 400, a stick of RAM, an old AGP card and HDD, a AT case (good old 486DX2-66) a 235W ATX PSU, but no mobo! If I got a new mobo for my main rig, I could finally build my kid son his own rig around the BE6-II with the 400 @ 450 (6*75, or.....heehee!) This will still be cheaper than a Duron/Athlon plus mobo, but again I AM in serious doubt...
if you wanna build your kid a rig then buying a cheap second hand bx board off ebay would be better, the chance of any improvement from buying yourself is not definate and it would be a shame to got to such expense and not get any improvement, and even if you do get an imporvement it won't be much. I'd stick with what you have for now as it is fast enough to last a while, such small upgrade just aren't worth the price.

:D I'm back upthere! I never tried 1.95Vc, and this even lets it run 3Dmark for over an hour! I also lapped my greenie and slapped a 40mm ADDA fan on it over the weekend. Let's see if it keeps running without crap over the week...

Yesterdaynigth she froze up on me after about 5 hours. Today I disabled the AGP memory (from 64MB to 4Mb) and right now the system is running for 8hours and 10 minutes, with SETI running permanently, and CPU stability test ran for 3 hours. I must say it looks good cuz it's also a hot day today. I'm gonna let CPU stability Test run overnight and post the results here tomorrow...
Lancelot
06-21-01, 04:30 PM
Yep! System is now running for a day and a half! Left CPU stability test 6.0 running overnight and during the day, totalling over 17 hours before I needed to use my rig! It sure looks good now! I'm gonna leave her 'burning in' at 1.95Vc for a week and see if I can lower it a notch by then. I'm now at 43C under full load, would like to see that a little lower if possible.
Well done Lancelot!! Yeah, 43C is a trifle high...I'd shoot for 35 to 38C. That would be just about right, I think...
Mr B
* I GOTTA get me one of them BE6 II's...damn curious to see if there's any more to be had from my C600 *

I have a c2 800 running at 133FSB righ now. I could not get it stable with the abit slocket above 130-131FSB but now I am Using the IWill slocket II and it seems stable, although I have only been running about 3Hrs... Well see...
