Okay, so basically, all Slot 1 computers are going to the entire project of an upgrade to Pentium III. All PCs are good to go and I assume that this PC will do.

Now, if I insert a Pentium III 600MHz 100MHZ FSB, will it work?

The current specs are:

Intel Pentium II 400MHZ

128MB RAM

4.2GB HDD

40X CD ROM

That 2MB onboard card

I want to make sure I just don't burn money into flames. Also, I went for the CPU support and in a list, created by users, the computer model was there, but I would like to confirm it. If it needs a special heatsink, I know how to go around. I'm really good with modifying the way they function.

I know that my board contains the second version, so it can take the 500MHZ, but also, that 44BX is a good one. It can take up to 850MHZ, from what Intel said.

The G1 appears to be very similar to the GX1 regarding upgrades.  If you search these forums, pablo_123456 posted several times about upgrading his G1 machine.  I believe the G1 will suffer the same issue as the GX1, namely that up to a certain bios version the 600MHz will work; after that it may or may not (it depends on exactly which 600 CPU you have as to whether the timing loop to inhibit faster processors reports too fast a processor or not). On the GX1, processors above 600MHz need bios A07 and no higher; pablo_123456 reported success with faster processors on his G1.  Processors up to the Pentium III 100MHz FSB slot 1 will then work in the GX1; and on a super socket III coppermine Celerons up to 1.1 GHz will work on the GX1.  You may have to dabble to find the equivalent bios version for the G1....

Well, there is also a Slot T adaptor for that too. Apparantly, If I use a Tualatin core, the clock ratio would be locked at x13 or x14. All I'd need would be to arage the FSB, in my case, would be 100MHZ. But, if the 600MHZ would work, I'd look to push that guy to 750 if I could.

But like you said, it may work or may not work depending on the BIOS. I will look at it today, and see what's the BIOS version. If it's lower than A07, do you know where I can get the BIOS flash update?

I'll look also for what he did, because that chipset is amazingly capable to handle very fast CPUs.

You can't overclock the 600 in the G1 by changing the multiplier settings; you can only run it at the stock FSB/multiplier. (OK there's some software utilities to allow mild overclock, but since they overclock the PCI and other buses they usually aren't worth the hassle...).  All the documentation, manuals, drivers and bioses for the G1 are on the Dell web site; just go to support.dell.com and enter your asset tag; or select the correct model from the pull down list.  Powerleap used to make a slot 1 adaptor for the Tualtins as well, but I believe they have stopped production.

Dang! I have A09! Will it do or do I REALLY nooed A07 or A10?

[peterfelgate]

As I said, I do not know which bios version, if any, might inhibit the faster processors on the G1.  My advice is to just try it, making sure you retain the existing case fan.

Oh, that fan will stay there. I'll have also the other one spinning with Y cables, or, if I'm lucky to find a three prong plug for it.

The only thing I;m a bit worried is that Dell is horrible when it comes to PSU wattage. It's only a 135W, but, I think it will be alright...considering that my friend's PC is a PIII, 128MB RAM, 6.4GB HDD, and all that stuff, and it's being powered by an 85W PSU.

Hi, Im new here. thought i'd throw in my experiences lol Right, I recently acquired a few Optiplex G1 units with the slot 1/Celeron 433 config and I'm trying to make it run on a P3 Coppermine 800mhz/100fsb socket370 using a slocket adapter. The only trouble I'm having is it goes like stink for about 5 mins then just shuts itself down. when i reboot i get a "previous fan failure" message. Im using a heatsink/fan off a socket 370 cely500 i had lying about hotwired into the existing connector. Ive tried the motherboard jumper on 400 and 500 and it seems to last a bit longer on 500 but i was just wondering if i'm fighting a losing battle here. Im using the bios version 10 and 192mb ram Thanks in advance for any advice from anyone who can help Is it possible to backwards-flash the bios and if so does anyone have v7 because the only version i see is v10

OK!

After a bit of experimenting I have a Pentium III 800 running a treat on a Optiplex G1 that used to be a Celeron 433 slot 1 hehehe

Used original fan on top of socket 370 heatsink and set slocket jumper to "force 100hz overclock"

The other jumper I have set on the 500mhz setting.

Still running bios v10

The slocket brand is 370SPD

That job lot of P3 800s is gonna come in handy after all :)

[lhuser]

I guess that sums it: I can run higher speeds. I'll try a Celeron 1.4 in it. I have the RAM at 256MB and a PCI 16MB GPU.

Oh and....can you..err...send me one?:P
