CPU Info Please

[Sweeper]

I was looking into upgrading my Mother's Gateway PC. It's a Celeron 400 MHz system. Well, after looking at the motherboard and talking to Gateway they said:
Motherboard supports Intel Celeron Socket 370/ 366 400 450 475, so you can only go as high as 475mhz Celeron Processor.
Please correct me if I am wrong. I was unaware that Intel had a 450,475 MHz Celeron. From what I remember, they had 366, 400, 433, 466 PPGA, 500 PPGA. I don't recall the 450, 475? If they did, please let me know. Would like to uprade from the 400 if it's cheap enough.
Thanks,
Sweeper

The 533 Celery is the fastest that I know of in that voltage line.

Be cautious not to get the 533a which is the lower voltage CPU.

I have one 533 here and really like it's performance.

Yep... 300 - 533Mhz at 0.25 micron, then they "flipped" them over and switched to 0.18 micron and lowered the core voltage starting with the 533A.

According to their charts, PPGA was available in 300A, 333, 366, 400, 433, 466, 500, & 533Mhz.

Well, Gateway informed me that the board will only see up to 475 MHz of speed @ 66 FSB. So it looks as though I can only go up to a 466. Not a whole lot of speed change. Maybe I will just slam it full of ram. It's cheap enough. It only has 64 megs now.

Sweeper, I am running a FIC VA 503+ motherboard with a K6-2 500 processor. The bios only "sees" a 400 mhz processor, because that was the limit when this board was sold. It runs the 500 just fine, reports 400 in dos on boot, Norton and other utilities like Sisoft Sandra all report the processor as 500, and running at 501 mhz. So, your moms board may verywell run the 500 or 533 if you have the jumpers on the board to get it there. I have the jumper options on my board to go to 5.5 100mhz, and overclocked my 500 to 550 once just for a test, but put it back to 500 for service.

I believe as long as your voltage and FSB remains the same, ie. like the chip you have in there now, you will be able to upgrade to 533 easily.

A friend of mine has a 450 PIII and Gateway stated that the most he could go up was 500.
We stuck in an 850 PIII and it ran fine. Of course we removed the chip because the voltage set on the board was too high. But it ran. Bottom line, multiplier settings are locked on the chip; you are already using a 66mhz FSB so everyhting seems to be in place for a smooth upgrade.

And yeah, the BIOS may not read it correctly but if you use an application like CPUID, it will tell the truth.

And BTW, gateway will use tactics only to get you to upgrade from them so be careful.

[Sweeper]

I thought I was right. I will talk again with Gateway to get this figured out. Looking to upgrade that old 400 to atleast a 500/533. Thanks.

Bovon-It is a jumperless Motherboard. Everything is run by the BIOS. And it's locked.
ck42866- I will take a look around at some 500/533's and see if I can come across one cheap.

Thanks,
Sweeper

Sweeper, when you say its locked, exactly what is locked?. The default multiplier is locked and you cannot change that?. If this is correct, then you would not be able to run a higher speed cpu above the multiplier settings already set. If I understand it, the buss speed must be increased, or the multiplier must be increased, or a combination of both.

Look in your bios and see what buss speeds are available...IE .. 66mhz, 75mhz, 83mhz, 95mhz, maybe 100mhz. Then see what (if any) multiplier options are available. If by chance, these all are locked at the default settings for the cpu it came with, you may be stuck at that frequency.

If as Gateway says, it will support up to '475'mhz, and it came with a 400, there must be some way to change the multipliers and/or buss speed in bios.

Let us know what you find in bios that will allow you to install a higher speed cpu, and set it up in bios for the proper settings.

Hey, Sweeper, got a part number on that board from Gateway? I might be able to get some info in regards thereto. The part number should be a 7 digit number either 40xxxxx or 25xxxxx.

As for OC'ing GTW boards, not gonna happen. They don't characteristically have jumpers on the boards (for multiplier/voltage) anymore and the BIOS doesn't offer any help either.

Bios locked: Meaning the bios controls the CPU multiplier and voltage. The bios is set to only run @66 FSB. It is also designed to auto detect the new processor and adjust the voltage and multiplier up to 475MHz of processor speed...from what I understand. Also, I have looked at the Motherboard and there are no jumpers on the board other than the BIOS recovery jumper. Your more than welcome to look at the specs.

Sweeper, if you flash your BIOS to 4F4JZ0XB.15A.0011.P09 it will recognize the 500MHz Celery and might recognize the 533MHz. I couldn't dig up any information about what voltages it supports so I wouldn't push it beyond the 533 unless you have some mad money laying around http://www.sysopt.com/forum/smile.gif

Oh, and here's the link for the BIOS should you need it: http://www.gateway.com/support/PRODUCT/DRIVERS/Bios/4f4jz0xb.shtml

Since the celeron is multi locked, as long as it is on a 66.6mhz bus, it should run at the correct speed regardless of what the bios tells it.

I have already flashed it with the latest flash. How did you come up with the support for the 500MHz processor?

Thanks,
Sweeper

[RandomGoon]

I used to work for Gateway and have friends that still do http://www.sysopt.com/forum/smile.gif Had them verify it with their tech info, it should recognize the 500 on boot but if not you can use the password reset jumper to go into "maintenance" mode and cause it to reset for the new speed. I think it's jumper J7H1.

Kewl. Thanks. Guess I will get a 500 Cel. and add another 128 megs of ram. Should run good enough for her.
Thanks,

No problem Sweeper, as I said I used to work for them and don't like to see people left hanging. I guess I still have some company loyalty >shrug<
