Radeon LE @ 89MHz???

[Finlay]

Howdy all,

Thinking about getting a Cu P3E and OCing on my P2B - everybody says you can do it with no problems except that your AGP will be out of spec at 89MHz. I know the GeForce cards can take it, but how about the Radeon?

Also, before I put money into extending the life of my P2B, does anybody know how much performance loss I'm taking due to no 4X AGP support? So far I love the LE - will I love it more if I upgrade to a mobo that supports 4X?

Thanks all!

I don't know whether the LE will take 89mhz; I just know that my modem can't take the 44mhz PCI speed.

I do know about the AGPx2 vs. AGPx4 though. I did a couple tests running my baseline setup for 3DMark2K1 and scored 2248 with AGPx2. My best score with AGPx4 (having many more baseline runs under its belt) is 2254, so I'd say performance is negligible.

The above scores were with a P3 700, Abit VH6(133A chipset), 128mb of ram, and a Radeon LE running stock except with the HyperZ hack.

Hmmm his pci will still be at 33MHz.

Yes. With AGP at 89, PCI will be 33.

I too am interested. I would consider a PIII 700E at 933 or else an 750E at 1 GHz (unlikely).

Otherwise, I'll have to try to find a 1 GHz FC-PGA 100 FSB chip somewhere for my BX board.

I have a LE (flahed to regular DDR) running on a sweet Soyo BX (6BA 100? something like that) board. The FSB is 150, so the Radeon is seeing 100MHz fsb! It runs stable, but at 100MHz fsb I could overclock the LE to 183MHz, now it will only run stable at around 175MHz. I just leave it at the (new) default of 166.

83 should be no problem. YMMV.

I've run my LE at 96 AGP bus for about 6 weeks,works great still does 200mhz.🙂89 should be cake

I'm sure it will work. Many recent video cards can handle the 89mhz agp bus speed. Geforce 1 can and that's old in video card times. 🙂

I just said that my modem can't take a 44mhz PCI bus speed (my motherboard automatically sets the AGP and PCI stepping - at 133mhz fsb my motherboard automatically sets the 1/2 AGP speed and 1/4 PCI speed), so I couldn't test whether my LE would run at 89mhz (or 84mhz, for the 125mhz fsb). If my modem could have taken it, I would have tried to post and play a game at 125mhz fsb and report my findings.

My first response was just to tell him that AGPx2 runs about as fast as AGPx4.

Great! Thanks for the input guys - I guess I'll give it a try. That is, of course, assuming I can find a reasonably priced P3E/100 here in Canada. Having to deal with customs is a pain in the butt.

I know this is a loaded question, but what are the odds of damaging components when OCing? Lots of people do it successfully, but what happens if it doesn't work? Does the computer become unstable, just fail to post, or do you actually fry things? If so, what are the odds? Tough to answer, but I'd love to hear some opinions.

Also, what are the risks in flashing my LE with a DDR BIOS? I've read the Howtos, and it seems like a no-brainer, but I haven't heard of anybody who had problems, which makes me suspicious. Is this really foolproof?

Thanks!

Hey, I responded to your other thread already... but.. where in Canada do you live?

In toronto I just got a PIII 700E (about a month ago). Cheap. ($199CAD). Plus, it overclocked to 933 no prob.

[Finlay]

Sweet! I'm in Ottawa. Where did you get your 700e? If they're not online I could swing by next time I'm in TO.

Thanks!

 

[Mkoh]

I think it was called Keit computers.

It's located on Sheppard, close to Victoria Park. I know that they had PIII 700E processors as recently as a month ago. But these are becoming hard processors to find. You got to act quickly!
