Problems upgrading Celeron CPU

[marcoco]

I'm upgrading my CPU.

I've installed a Celeron 1.10 Ghz, 256kb L2 cache, 100mhz system bus
into my Chaintech 6vjd2 Mobo.

when I power the PC on, the CD light flickers, and the HD light goes on.
Eventually the HD light turns off but I dont get any video or beep.

I get a similar response when switching back to my PPGA celery if I dont reset the CMOS.
Unfortunately the CMOS reset doesnt help for the new processor.

I've decided that either my jumper settings are wrong. I've tried different variations (100mhz X 7.5). What should they be set to (manual only goes up to ratio of 8.0)? or there is a problem with the CPU (maybe incompatible) ?

In theory, it should be:

100 Mhz FSB x 11x multiplier = 1.1 Ghz

 

[marcoco]

My manual doesnt give an 11X multiplier option, it only lists up to 8X.
I've decoded their jumper scheme and believe that the highest ratio hardware setting is 9.5X.

If I use 8X, shouldnt the pc still boot up using 100X8? or would I get the symptoms that I described above?

Is it possible that my mobo cant handle the 256kb cache? The specs are pretty vague : "Supports Intel and VIA Socket 370 processors up to 1.2GHz"

According to this review on active-hardware.com, Alteration of the clock multiplier to a setting ranging from 5X to 12.5X can be accomplished using jumpers JP12.


I'd like to see the jumper configuration, but someone hacked the chaintech website

 

[marcoco]

Yup, I saw that..
I uploaded the section with the jumpers here.

There are 4 jumpers and the settings look something like this (where 1=on, 0=off)
The ? values are the ones not identified in the manual.

0000 9.5?
0001 8.5?
0010 7.5
0011 6.5
0100 9?
0101 8
0110 7
0111 6
1000 5.5
1001 4.5
1010 3.5
1011 2.5?
1100 5
1101 4
1110 3
1111 2?

dang - there are 16 possible settings @ 2^4

So if it starts at 2.5 multiplier, then that will only get you to 10x on the 16th position. I don't know how you could do it, because I'm pretty sure the multiplier is locked. So any other selection than 11x will not work (?)

Maybe with a bios upgrade?

edit>> chaintech tech support, maybe they can answer u (for free?) tech@chaintechusa.com

When I run my old PPGA 500 processor, it doesn't matter what the multiplier is set to, it always boots up at 66X7.5.

Is it possible that I have an incompatible CPU?
DOes my mobo not support Tualatin FC-PGA2 processors?

I'm guessing that this is my problem. Is there an easy way to upgrade a FC-PGA to a FC-PGA2?
I've been reading about the mods and they sound pretty intense, and powerleap is almost the same price as a motherboard upgrade.. are there cheap slotkey style adapters out there?

The writing in the Chaintech manual implies that you can force a multiplier setting.
In the review they are running a Celeron 1.0Ghz at the 133mhz setting.
It might be an unlocked processor.

Why not try running it at 8x 133mhz (about 1064mhz)?
What core is this processor? It mentions the voltage setting is automatic
maybe it doesn't support the voltage this Celeron needs.
YMMV

Sounds like it. Multipliers are locked.

DOes my mobo not support Tualatin FC-PGA2 processors?

I guess not. The highest cpu that your board supports is probably a Coppermine 1.1ghz/100mhz 128k cache Celeron. If you are the adventurous type, there are work-arounds for the BX chipset. However, I have no idea whether the same hacks apply to your motherboard.

Almost forgot, you wanted an alternative to Powerleap. Well, I believe there is only one:

370 GU Socket 370 adapter FC-PGA2 to FC-PGA for Intel Tualatin Core Cpu's - $29.95
