Project "Celeron"

[PardeGT]

I have an nvida riva 128zx card that is with my ibm p2-400. I'm playing around now with an abit bx133 raid board and a 766 celery.

I was doing some reading on overclocking and found a program to overclock the riva 128zx. The riva 128zx was built around the 440bx chipset and the agp bus is supposed to be at its best around 66mhz (thus the 1/1 setting for a 66fsb and a 2/3 setting for the 100fsb) and yet the riva has a 100mhz 128bit architecture. Are these not related? How do they correlate or are they independent? I'll be running around 95fsb with the celery I think - I got it to post to 1150 (11.5 x 100 @ 1.85v) but this was just a post - haven't installed windows yet. Should I use the 1/1 agp setting?

Now, I should mention that this vidoe card is just laying around and thought I'd play around with it - don't want to stick many $ into a vid card as I don't do much graphic intensive apps/games. I also have an ati xpert98 card laying around - don't know if either is better than the other.

On to some other questions I have. How can I tell what stepping my celeron has?
It says SL4P6 on it if that is a clue. Is pc133 known to step down to a 66fsb? I have a stick of pc133 corsair cas2 and it seems to run fine at stock 66fsb setting and of course fine at the 100fsb. Also, what is system1 and system2 temps and how are they measured? These are shown in the bios-pc health along with the cpu temp(thermistor).

Well, that's probably too many questions for one post but thought I get them out before I forget them. I'll post what I get for a stable speed with windows running.

Thank you for all replies!

The clock speed of the Riva and the AGP bus speed are unrelated. I would advise you to keep the AGP bus as close to 66 as possible.

I advise you to install Windows at stock speed first and take a Ghost image or something, THEN try overclocking.

That's what I thought George on the vid card but thought I'd confirm. I was going to drop down to stock to install the os but got anxious to see how the celery and the SK-6 would perform.

Any thoughts on the other questions anyone?

AGP is supposed to be 66, PCI is supposed to be 33, keep those as close to default as possible, preferably not going above 37 on the PCI (do your math ).

Agreed on the backup. It's very possible, and depending on how high you go sometimes likely that you'll corrupt data on the hard drive with high bus speeds.

Yep, I'm using 1/3 and 2/3 settings for the pci and agp respectively when I'm overclocking. When I get windows set up the way I want it I'll make a ghost of it. Does that take very long?

Also, any info on the stepping of the celeron or memory experiences from the initial post? I checked the abit site but couldn't anything on what system1 and system2 temps are. System2 always runs higher though. I figure system1 is the northbridge and runs cool (30C) because of the fan on it but not sure about system2 it goes up to around (40C) during overcocking. Don't think its the southbridge as it stays cool to the touch.

Thanks guys

I was reading some online celeron info and someone mentioned that celerons without L2 cache are better overclockers than those with. He said disabling the cache will help overclocking and increase stability while doing so. He also said this one one of the main reasons Intel put cache on the celeron (besides a selling point)- to limit their overclockability.

Is this true or a load of crap? I know the celeron 300a's had cache and were of the best celeron overclockers.

From above posts:
Does anyone know what the system2 temp is actually measuring?

The Celeron 266 and 300 had no cache, the 300A was the first with 128k. I have a 266 Celeron in my shop and it double clocks to 533Mhz at the standard voltage and runs 40'C under a full load with a standard heat sink and fan. I'm sure the sucker will go higher, but the board I have for it only goes to a 133Mhz FSB, so that's all I can get out of it. I have double clocked about 6 others for clients, all stock voltage and stock heat sinks and fans.
