Eug: Andy Hui suggested you for ASUS P2B and Coppermine question

[BCinSC]

I have P2B-LS rev 1.03 BIOS 1012. ASUS site says rev 1.04 is needed to run Cu chips. Know why? Am I SOL with the new Slot-1 700 I bought?

 

[Eug]

Hmmm...

First off, I don't test these specifically but have been following the thread here:

http://www.ctechnet.com/hardware/asus.htm#10100

Worked with P2B-LS rev 1.02 or up. (confirmed)

- Worked with IWill Slocket II Rev 1.1
- Worked with Asus S370-133 Rev 1.01
- Worked with Slotek SL- 02A++
- FC-PGA 500E Worked with overclocked frequency to PIII 515/103, 560/112
- FC-PGA 550E Worked with overclocked frequency to PIII 566/103, 616/112
- FC-PGA 750E Worked with overclocked frequency to PIII 840/112
- Normal operating temperature around 38 degree Celsius with 1.8 Volts.
- Worked with bus frequency of 75MHz, 100MHz, 103MHz, 112MHz, (Slocket must be set to auto bus frequency detect. Set the bus frequency jumper on motherboard)
- Worked only with 1.80 volts or up on FC-PGA (System will not boot if set the jumpers on Slocket to 1.60 volts)


Rev 1.04 is required for proper voltages with the FC-PGA chips. Older revisions MAY work with those chips, albeit not 100% ideally. For example, my supposedly incompatible P2B (not LS) works, but in only in 0.1 V increments. If I set the slotket at 1.65 V, it USUALLY boots at 1.7 but every once in a while it refused to boot. If I set it at 1.7 everything is perfectly fine though. However, I know one guy on this board with an even older P2B who could not get his Cumine to work at all, until he set his slotket to 1.8 V. No voltages below 1.8 would work.

With your 1.03, so far no one has been successful below 1.8 V, but 1.8 V works fine. I dunno how many people have submitted their experiences though. If it works, fine. If it doesn't then you may be SOL with a Slot 1, because you can't manually set the voltage. If that is the case, then a better bet would be a FC-PGA with slocket which has voltage jumpers. Note that as of last month there were no slockets that compensated for a motherboard's inability to run below 1.8 V.

I cannot alter the voltage with a retail Slot-1 P3/700 that I am aware of, so am I going to fry it with this mb?

 

[Eug]

What I'm saying is that you should try it and see what happens. Either it will boot, or it won't. You won't fry it though. And if it doesn't work, make sure your memory settings and AGP are set correctly first before blaming the CPU.

 

[BCinSC]

I appreciate your help. Lord knows ASUS hasn't replied yet.

Thanks,
BC

 

[BCinSC]

No go. Damn. This rev must not be able to hit required voltage or maybe doesn't recognize multiplier (jumpers on the board only go to 6x).

Guess I'm SOL. Bummer.

 

[BCinSC]

And STILL no reply from Asus. Bastards.

 

[Eug]

Well, in truth, their website plainly states that your CPU is not supported on that board.

However, we have been able to make some unsupported board/CPU combos work after a fashion but I don't expect support for it.

Why don't you just call them? I found email either is ignored by most large companies, or else is answered weeks later. (I think my record is about 2-3 months.)

 

[BCinSC]

You're right. I guess I was hoping to get an Alpha-geek techwho'd tell me to solder a resistor in such-such place to alter core voltage or something. Sold the 700 and am getting a Katmai P3/450. It's a compromise, but it'll do.

I have the 1.03 version of the P2B-LS board. I used an Abit slotket III with my new 700 FCPGA, set the volts to 1.8, and it POSTs at 783, with the MB's 112 FSB. Loads Windows 98 perfectly and runs just fine. The CPU voltage is listed at 1.8v. I have tried to set slotket jumpers to 1.65 and 1.75v with no luck, won't even send signal to monitor. So it seems to be worth a try for those who have the 1.03 revision and a CPU to swap around. I plan on buying another 700 to sue on this MB and extend its life. It's a great board for features and stability, just not an overclockers board. Anyone know of a slotket that holds two CPU's for dual action?

 

[Eug]

Yeah, 1.8 V is the magic number for those P2B boards that don't natively support the Cumine chips.

However, BCinSC had a Slot 1 chip.

"Anyone know of a slotket that holds two CPU's for dual action?" Doesn't exist.


BCinSC, why not get a PIII 700E FC-PGA plus slotket with voltage jumpers?

 

[BCinSC]

'Cause I didn't think about - brain fart. Now I've got a P3/450, which will have to do. As always, thank you all for the info.
