ASUS P3B-F What's MAX CPU speed for this mobo?

[LeRNeR]

I have an Asus P3B-F Bios version 1006. All the info from Asus and other websites list differing maximum cpu speeds. Anyone of you have experience with this motherboard and P3...say.. 800-850mhz? Asus 1006 bios version notes say: " Support 566MHz and 850MHz CPU with clock ratio equal or greater than 8.5x. . " I'm not sure if that is the highest or not. Please help!

ThanX!!

No poll needed

Please read the FAQ: What is the fastest processor I can use on my Slot 1 ASUS motherboard?

aw that was too easy.. I was just havin some fun on the poll! Thanks for the quick answers!

Here's a trick question. Where does one find the latest .awd bios file, posted (v1008 Beta 003) from your link? Asus only posts up to v1007 beta 1. Maybe I just suck at searching. I dunno. Thanx again my friend!

BIOS Version 1008 Beta 003

Coppermine Pentium III 1000 is most likely the top CPU you can put in there.. the Coppermine core is supported, and I believe the top CPU made in the Coppermine core was the 1Ghz PIII.

Thanks for the bios link, I upgraded the motherboard to this version and it worked great. Now I just need to finalize my processor purchase. I'm just about to submit an order to googlegear.com for a processor, but I thought I'd ask this quick and important question. I'm worried about the TNT2 AGP video card & slot running at 89Mhz. I'd rather buy a slot1 proc @ 100mhz fsb but they are more expensive. So my question is, if I buy this Retail P3 866Mhz 133fsb 256k Slot1 processor for the P3B-F bios version 1008 beta004, can I change anything to run this FSB at 100mhz?

 

[AndyHui]

No. Intel processors are multiplier locked. If you run at 100MHz FSB, your processor will be running at 650MHz.

 

[LeRNeR]

Correct me if I'm wrong on these numbers:

Defaults for the P3B-F= fsb 100mhz, AGP bus 66Mhz, PCI bus 33 Mhz


I read that the AGP slot will run at 89Mhz if I have 133fsb. The AGP TNT2 display adapter won't like that at all I'm sure. I could always just go with a PCI display adapter. No big gamin on this comp anyways. Does this mean the PCI bus also runs out of spec while at 133fsb as well?

 

[AndyHui]

You have the default numbers correct.

TNT2s may or may not like the 89MHz AGP. GeForce cards have no problems with this speed, so you may want to consider purchasing a GeForce 2 MX or a GeForce 4 MX or a GTS-V.

A couple other cards I ran at 89mz agp without problem on my aopen ax6bc were the voodoo 3 & 5 and an asus ddr gforce 6800.

Lerner, did you just pick up that board from Ebay?

I've been playing around with a P3B-F, Rev. 1.04 the last week, and the thing is amazing. The 440BX chipset is very robust, and this board must have good voltage pumping through it or something.

I tried two CPUs. One 600E flip chip only goes to 142-144 on a P3V4X (not a shabby board at all) or P3C-E (Intel 920). It goes to 150 on the P3B-F, and stable in 3D at 1.80 volts.

An 850E will only do 112-116 on the other boards, but will do 124 stable on the P3B-F. Have yet to have a hang on the boot sequence, or corrupted files in Win98SE.

Only irksome thing is the Alpha P3125 heatsink will not fit on the P3B-F, since it touches the ram in the #1 slot. I tried seating the CPU in at an angle, but it won't boot. Have to use a Golden Orb, but temps are only about 2-3 C higher.

I've been running a Radeon 8500 and it ran OK at 150 FSB (AGP at 100 mhz), but even at 83 mhz, the ram is really hot to the touch. And I only ran the system for a week, so don't know long term consequences.

well thanks for all your info on this subject. I've pulled the trigger, and purchased the Retail PIII 1Ghz FSB @ 100Mhz Slot1. It was $179 @ Googlegear. 256MB Ram and a nice new 40g 7,200rpm seagate will make this old box a rather disguised speed demon.

Did you say you got the 100 FSB 1000 PentiumIII Slot 1? That chip doesn't overclock very well. The one to get is the 1.1 or 1.0 cDO flip chip. Some people are getting those to 133 FSB, but they are hard to find now.

But if anything can overclock it, it's the P3B-F, or maybe a BE6-II. Let us know how high you get.

 

[LeRNeR]

actually this is just an old comp I sold to a friend of mine a year or 2 ago. The Quantum 26G HDD died! Instead of a PII400 + 128MB +5g Old Seagate C: drive + Dead 26G D: drive, we now have 256MB RAM + 40G 7,200RPM, 1Ghz CPU.

 

[LeRNeR]

overclocking is unnecessary. The stability is enough to make me satisfied.

 

[LeRNeR]

just an update... The P3 1Ghz@100FSB is running great on this P3B-F rev. 103 Bios v1008 Beta 003. The processor is overclocked to 1120Mhz at 112FSB and 256MB at 112Mhz. It's running cool and stable! Thanks for all the assistance!!
