What are some AGP bus overclocking tolerant cards?

[TStep]

I recently acquired an ABIT BX133 motherboard w/ bad caps dirt cheap and had it repaired, so good as new. It has a BX chipset however. I also have a multplier unlocked PIII 800, but with a 133 bus. I am also entertaining getting a cheap Celeron 1.0a or 1.1 (tualatin w/ adapter) and overclocking it to the highest bus speed I can get to.

In any case, the BX chipset only allows a 2/3 divider on the AGP bus. So, a 133 fsb would set the AGP bus to about 89mhz. I would like to toss in a Ti4200 (real inexpensive now for the performance you get) but I am unsure about the ability of the card to operate at this highly overclocked bus speed.

Anyone have any experience with this card or anyother at this high bus speed?? I have heard ATI's do not like anything over 70 or so and I do not like the current PCI options (too expensive for what you get).

Thanks in advance

I was just about to post not this question, but something similar.

I don't know the answer to your question, but I can tell you that the 9800 Pro I recently combined with an ABIT BE-6 II (BX chipset) and a PIII 933 with a 133 FSB will not work above the 70 AGP bus speed that you reference.

There might not be any thing worse than having to underclock your processor. I have to run my 933 at 700. I suppose I could crank it up to about 735, but why risk the card's health for that small increase.

I also have a multplier unlocked PIII 800

I'd kinda' like to see that unlocked PIII.

PM me an email and I'll send a picture of the unlocked PIII tonight.

9800Pro in that system is a total overkill!!!!!!!!!!!

Of course it is.

I'm very compulsive. Woke up one morning and hit AT video forumn and saw a thread about the 256 meg 9800XT or Pro XT or whatever it's called and decided I just had to have one. If Circuit City had had the 256 meg XT or whatever it's called, I'd have gotten that. I had to settle for the 9800 Pro. It makes no sense.

What makes less sense is the fact that the only games I have are FAKK2, Alice, and NOLF. After all these years, I've only played and completed Alice.

Makes those 3D screensavers look good, though. I really like that Gargoyle one that comes with my driver installation disk.

Anyway, this ain't my thread, so enough about that.

I would hope to see some good answers to the original question. I should have asked the same questions before I bought my card.

I don't have an email account set up and don't want to set one up seeing as how my i-net service terminates end of day tomorrow. I believe the BX133 takes a Socket370. Does yours look like any other Socket370? If so, I'll just do a search.

Did you unlock it yourself or did you buy it unlocked?

I agree with PlasticJesus that its all about the fun, challange, and tinkering. I know I can get any AMD w/ DDR system and outperform the BX133, but been there done that.

Still looking for someone who has knowledge of up to date AGPcards that will work @ 89mhz. Preferably a Ti4200.

On the PIII 800, it came unlocked. Looks just like anyother PIII, but it has one or two pins not installed by Intel. I bought it in a lot purchase and it came with two unlocked 733s which I have since sold. Someone must have gotten out of Intels engineering department. The sSpec stepping code starts with a Q and ends in ES. I can't remember the numbers in between. Upon boot it defaults to a 3x multiplier and a bus of 133mhz looking like a PIII 400 with a 133 bus. A motherboard for this cpu must have multiplier adjustment.

I had an unlocked PIII once, it sucked. To begin with it was sold to me as a PIII 933, but turned out to be a PIII 800 engineering sample. And worse yet, when I installed it in a Gateway system I was trying to sell, it dropped to the lowest multiplier, giving me 400MHz. I couldn't find any enthusiast who would touch it and ended up getting rid of it at a loss on eBay, so I could get a real PIII 933.

Anyway, the BX is what every newer chipset wishes it could live up to. Nothing could touch it. I had a couple GeForce2's and a Radeon DDR both live with AGP clocks up to 100MHz. meanwhile most Radeon 8500's and newer, and most GeForce3's and newer, won't even stay stable at 89MHz AGP. Sorry.

Well, I ran an Abit BE6-II MB that only had a 2/3 AGP divider at ran it with a P3 700@933 as well as a P3 1.0ghz @ 1.33ghz. As both of those were running at a FSB of 133, the AGP was running at 89mhz.

In those systems, I ran a GF2, GF3 Ti200 (OC'ed to Ti500 speeds), and a GF4 Ti4200 (OC'ed to 4400 speeds).

Thanks for the responses. I might give the 4200 a try then.
