FSB limit with radeon

[davidpowell]

Hi,

Just a quick question as one thing ive noticed with the FSB in PCs with people running a radeon9700pro is on the epox mobos not many seem to be at 200+ or near 200. Maybe im wrong, but ive noticed alot of Geforce cards in the 200's and how people are getting 220mhz on a 1/5 divider using an 8k3a is beyind my current abilities of imagination.

Any tips from anyone using a Radeon and getting 200mhz speed, if anyone using an epox mobo, would be greatly appreciated.

Before going on my stats are as follows:

Epox 8k3a+ using 2815 bois (seemed fastest when i tested 2912, 2815 and 2822(?)...
Athlon xp1800+@10.5x173mhz 1828mhz @2.050V
Corsair XMS3200DDR cas2.5 512mb @ 2.8V (rock stable, doesnt like 2.9-3.0V) running turbo settings, rams good up to 185 atm)
Radeon Shappire 9700 pro
Western Digi Cavier drives
1 PCI card ISDN asus
windows XP SP1

Current record 14790 3Dmarks

Main problems at high FSB

I get corruption in bois in bios and it rarely starts (might be ram) upwards of 185mhz FSB with the radeon, the PCI mhz must be 38-39 at this setting, not so high...

The RAM should take 200mhz anyone with a similar setup got any pointers, and the 2912 bios didnt really help and was slower at 173fsb. I have all multi's freed on the chip so Im gagging to get my ram running properly.

I found my radeon 8500 clocked higher than my GF3.

I also found that I needed some VERY good memory and plenty of voltage to get much above 200 as well as the 2912 bios.

this must go down as the most unhelpful forum in history, ill take my problems somewhere else....

Feel free, however I cannot seem to see what has bought you to this conclusion.

Only thing I can see is that no one offer'd to go to his house and fix it for him! I am not trying to be a smart a$$ but he didnt realy give anyone a chance to help him. I hate to see people leave our forum like that, but if they are going to be like that, let 'em!

If any non UK residents would like to fly me out to there location so I can overclock there PC id be very happy to help.

First off, Mr. Patience, this is a known problem with the R9700 and not an EPoX problem, so don't blame it on your board and try to give us a little time to respond.

Plus, I am sure that WD hard drive just loves those high bus speeds. I know the one I have on my shelf did, and thats why it is there!

[EPoX Tech]

What revision of Sapphire card is this ?

[ap0calyps]

Known issue???? Are you sure? I just thought the 9700 cards couldnt handle high AGP speeds. Thats why I got 8K9A2+ to boost AGP voltage, but it seems to have been removed from the BIOS, as its in the 8K9A BIOS. Anyways is there a known issue with the card? Also is the 8X BS sorted out, my card is unstable as hell on my 8X board

Its a simple enough question.

What revition of saphire 9700 (printed in silk screen on the card)

[Bring the Noise]

Well I was going to answer with this.

I have a ATI Radeon 9700 Pro (one of the first ones released) and an Epox 8K3A+.

Testing the 2a10 bios I could not get stable vid over 195 (with lowest memory timings and processor downclocked to its default speed).

I know if I put my Visiontek GF4 Ti4600 back in I could probably hit 210 or better before vid problems.

So it would be the vid card, not the motherboard.

Nvidia makes boards that are usually good at handling out of spec AGP speeds. ATI did okay with the 8500's, but the new 9700's don't do it so well with out of spec bus speeds.

Impatience is a vertu... ya may want to loose that vertu, and find why patient people prevail.

[ap0calyps]

So is there a new "revision" 9700 that takes high FSB better and fixes 8X AGP issue, or is there sill an AGP 8X issue?

[bldegle2]

Got a Saphire 9000Pro, 128meg, Powered by ATI, been all the way to a FSB of 212. Second one though, first one crappeda after two weeks, second has been a dream.

I would like to report on the 9700, however, the first one they sent me was fubared from the get go (garbled colored boxes, nothing else, also made by Sapphire, could hear it booting all the way into Windows), replacement expected tommorrow.

What revision Sapphire 9700 Pro did you have above 200FSB? And what motherboad? Any AGP voltage mod?

Thanks

[bldegle2]

no volt mod needed, the 9700 card comes with an additional 4 pin molex plugin that connect directly to the PS.

MB>8k3a+.

like i said, i am expecting the 9700 replacement today and will report back when installed.

i see no reason for the FSB limitations, it is basically the same card really juiced with some good chips.

i will say this, and i hate too, but i have too.

i also have a Chaintec Ti4200 SE, 128 meg, and although it benches lower than the ATI 9000Pro, the video quality is slightly superior to the ATI, crisper edges and much clearer to the eyes, a small but noticable difference. and as far as gaming goes, can't tell the difference.

all my video cards run the 200FSB and beyond, if i want them too, i found the sweet spot to be around 184/185 FSB with my setup, your mileage may vary.
