How to get the best of my new P3 800?

[Door Knob]

I just built my very fist sytem. It goes as fallows...
Asus CUSL2 board.
PIII 800mhz PC133 FCPGA
a slightly better than standar heatsink...runs at 14 degrees C not OC
Rage Pro 128 Graphics card
Micron PC133 256 Megs of SDRAM

As you can tell I didn't think of overclocking till after I put it all together. Just wondering where you think I can, and should, go with it.

Let get this clear here first... . Is your P3 800 processor 133mhz bus or 100mhz bus chip??

If it's 800EB (133mhz bus), you are screwed big time for overclocking. U can go upto 900+/- mhz. and that is not even guaranteed. What stepping is your processor? With cC0s you might be able to hit 900 or slightly more i.e.. 906mhz, 912mhz only if you have real good freaking RAM.

If it's 800E (100mhz bus), hmm... I dont know... not a best choice but.. with very good cooling(some Nitrous cooling), you can probably go 1064mhz and or maybe break 1120?.. you can dream that for now.

On a 800E chip Without any added extra cooling, you should be able to bump the FSB to 112 or 114mhz. that's 912mhz right there. Leave the AGP and PCI ratio divider as default..

Sounds like it is the 133 bus 800, so that is not the best overclocker available, but play around with it anyway. Anything better than 800 MHz is a bonus, in my opinion. That's how overclocking originally first got started. By the way, is that 14 degrees C. a typo? The ambient (room) temp of my home is normally 20 C. and some people complain that's too cold. I think 14 C. is equal to about 56-58 F, off the top of my head.

About the only thing you can do is look into FSB overclocking
and try to get it running at 140 or 150.

Any higher than that, your ram will most likely hold you back,
unless one of your PCI cards beats it too it.

I got this one running stable at 150 at stock voltage, and
the performance/benchmarks are up quite a bit from
default settings.

Although you wont get the same kind of extreme increases
in CPU freq. as you do with the 100mhz unlocked chips,
with FSB overclocking, you are OC'ing the entire box.

I noticed that except for the MB, (I got Abit VT6X4),
our systems are almost identical.

When I was fiddling with my settings, the Micron 256mb
ram chip would run fine at 140 or 150fsb with the cas2
setting. After I added a 2nd one, had to go to cas3 at
150fsb, although it would still run cas2 at 140 with 512mb
in.

I have left mine at 150fsb, cas3 since this was still just a bit
faster on the memory benchmarks than 140fsb, cas2...

I have an 800EB on an Abit SA6R with Corsair PC133 CAS2 RAM. I've tested it stable at 960 (6x160) but currently have it set at 900 because I didn't want to leave the PCI freq up that high. I had the RAM set at 3,2,2 at 160. :)

Thanks everyone for the input. And yes, the 14C is correct. My dorm room has incredibly heating because of where I am in my building so my computer is placed next to a open window. Even with cover on the venting on my case lets plenty of cold air in. Talk about the cheapest cooling system around..

hey knob i made the same mistake as you....7 months ago when i bought this system (p3800eb) i didnt even know what overclocking was. tough luck ohh well ..ive got mine at 900 (after some serious burning in) runs fine.....im just using no name memory works fine @150. Our setups are fine i dont think that too many applications will make it break a sweat yet.

yeah but 900 is pretty much the max unless youve got some sweet ram, but even then 960 is pretty much the limit. oh well next time hang around here for a while to find out whats a good overclockable processor

P3 800eb 133fbs

Got mine running at 1 gig (showing in benchmark 2k)

166 fbs 1.70 cv

Ive only had it 3 weeks but Its been running at that from new, and it will stay like that. Its solid as a rock. Ive had no probs at all, apart from having to upgrade the stock cooler.

If your mb goes to 166fbs go for it man

hey fingers what kind of ram do you have? my mobo unfortunatly only goes up to 150.

To be honest I know ManFriday, 1 stick is 133 for sure. But the other 128 is out of my old compaq which had a slot 1 p450 with 128meg as stock. I might be wrong but it could be only 100, as the board only went to that. I cant see compaq putting 133 if thay only needed to put 100 in?

There must be a way to check but I dont know how (

[OpenFriday]

look on the ram...well on mine neways there are sevral places where it indicates that it is pc133....i dont think there are many sticks of generic pc133 that do 166. so i doubt that your other stick is pc100. especially if it came out of an older compaq. i dont think compaq is known for their parts to be very overclockable. unless you got some majic stick of ram that got 66mhz over its rated speed id bet its pc133...you know what .....i have no clue.....why in he!! would compaq have a stick of ram that can do 166? well i wouldnt complain you got a virtually un-overclockable processor and ram from a compaq to do 1gig? youve overcome what some thought was impossible. i suggest you not question why it worked....rather enjoy the satisfaction that YOU did what very few if not no one has done.
