I'm trying to upgrade my cpu above the 500 mhz celeron chip i have it in it currently. I cant seem to locate the specs for this motherboard. The computer was originally a HP Pavilion 4535 with the motherboard being the only remaining original component. the engraved label on the motherboard says MEW-VM. i ran a scan of my computer at esupport.com and it says my motherboard was an ASUS Hawk, according to Hp.com the motherboard that came with the computer was a Cognac Trigem motherboard with a phoenix bios. my bios is currently phoenix 4.06.6. according to an asus forum the MEW-VM was manufactured by asus but a owned by HP and HP has the specs, which i cant find on their site. i'm trying to find out how high i can upgrade the cpu.it does have a jumper setting to change to 100mhz from 66. the motherboard also has an engraving for the setting for 133 mhz which is the same setting for the 100. a long time ago i tried putting an 850 celeron in it twice, but both chips got fried both times. any specs or info would be helpful

Try using a utility called SIW.exe to get more information on the MBoard. Things like the chipset will help determine what can be supported.
Also the BIOS settings may help by checking possible adjustment range for FSB & various voltage settings.
Find SIW below. Download the standalone version.

Most OEM boards are clones of retail boards but with minor differences...the most obvious being a crippled OEM BIOS. If you have a look at the ASUS support page, you *should* be able to determine which board the Hawk is based on. There are 2 dozen socket 370 boards that have a model number beginning with "ME" & 6 boards that have a model number with "MEW". If you take the time to sort thru them all, you *should* be able to find your board:

Even so, upgrading the CPU just to get a couple 100MHz wouldn't give as much of a performance boost as adding more RAM. However, if the board maxes out at 256MB or even 512MB, you might be better off downgrading the OS to Win98SE/ME/2K. Or rather than running a 8-10 yr old OS, you might wanna try a 2008 version of Linux.

"And that's the fishing line, because Sharkboy said so!"

wow 3 responses nice. all good info
i downloaded the siw utility and aslo used belarc advisor. both say my motherboard is
Board: Asus HAWK 1.00
BIOS: Phoenix Technologies LTD 1.03 08/20/99
north bridge intel i810 revision a2
south bridge intel 82801aa (ich) revision a2
socket 370 ppgain the phoenix bios the frequencey multiplier goes from 2-8 in .5 increments
according to an old hp forum i stumbled on last night, my hawk can't go past 500 without an adaptor, like powerleap's neo s370 or a lin lin. both of which ive been having a hard time finding to buy.
of course, i went ahead and ordered a P3 1 ghz FSB 133mhx FCPGA based off of HP's motherboard specs for the 4535. looks like it's the wrong motherboard's specs, unless the Hawk is the same thing as the Trigem Cognac, which looks very similar to my motherboard with some minor differences. so i may need to just get a new motherboard or that adaptor if i can find it.
any advice or additional info based off my listed specs?

If you looked at the link I provided it states the 2.03 version is the one that will support faster processors. Read at least the first page of responses on that link.

yeah i read that link. the 2.03 version is a hardware build i believe with a bios version of 1.03. which is the version that is avaialable on this site. i think i may have alreay updated the bios version. my bios is listed as version 1.03 but is labeled Phoenix not Hawk.the build version is the ASUS Hawk 1.00 and i havent found anywhere on if or how this can be upgraded.

You're missing the point. You'll get much more out of a RAM upgrade than you will out of a CPU upgrade. If you're stuck with 256MB RAM, it doesn't much matter if you have a 500MHz Celeron or a 1.0GHz P3. Besides, you ordered a 133MHz FSB CPU for a board that only supports 100MHz FSB so even if it works, it will only run at 750MHz.
Here's a 1.0GHz/100MHz FSB P3 for $13:

"my bios is listed as version 1.03 but is labeled Phoenix not Hawk"
Hawk is the name of the board...Phoenix is the name of the BIOS
"And that's the fishing line, because Sharkboy said so!"

on the bios, that would be my logical assumption as well. but hp.com lists the Bios specifically as a Hawk Software Build 2.20.15. basically most of my problems all stem from that i don't have any proper motherboard specs. Hp doesn't list anything on the Hawk and some of it's specs for my 4535 pavilion just don't match up, like the motherboard for example.
i think my Ram max is 256k, from all the info i've been able to dig up. figured the only way to upgrade besides buying a new motherboard would be the CPU. but Jam says that my cpu upgrade won't even matter without more Ram. the board has only 2 Dimm Ram slots. both installed with 128. but after using SIW suggested above i did notice that one was SDRAM 125 and one was SDRAM 133. maybe i could change the 125 to 133 to help, but im not sure how much that would accomplish.
not sure how Jam figures it only supports up to 100 mhz FSB. it has a jumper setting for 100/133. my bios mutlipliers only got to 8 for frequecey. so, if was going to be able to do a gig for speed, 8x133 is 1064. but, then again, im just assuming how this works and even though 133 is a setting stamped right on the motherboard, it could have been blocked out or somethingplus, i read that due to the coppermine cpus and other faster cpus require different voltage and a few other minor differences that would require an adaptor like the powerleap's neo s370 or a lin lin adaptor to get a faster cpu to work on an older motherboard. i bought this thing like in 95. on one forum site i was told the fastest would be what i currently have, 500, without this adaptor.

It doesn't matter what you set the multiplier at, it won't do a thing. All the old Intel CPUs are "multiplier locked"...changing the multiplier setting will have no affect.
As for the RAM, according to the old JEDEC spec, all PC100 *should* be able handle up to 125MHz...all PC133 *should* handle up to 143MHz. For whatever reason, some PC100 is recognized as PC125, some PC133 is recognized as PC143.
EDIT: I had remembered reading the 100/125MHz thing a long time ago & what I wrote above isn't entirely correct. The max MHz capability is determined by the type of memory chips used on the module. This link may explain it more clearly:

"And that's the fishing line, because Sharkboy said so!"

probably right.
went to a site for the phoenix bios, which directed me to esupport.com. i sent them an email on my comp for a bios upgrade last night. i talked to them today on the phone and they said that they were the ones who originally created the bios for the MEW-VM (hawk) which is now not really being supported by hp or asus. they said they created a brand new bios upgrade for this motherboard dated 12/2005. mine currently is 8/20/1999. the updated bios has a completely different name. problem is it costs 39.95. but i guess it will allow larger hard drives and cpus and a slew of other options. worried though that this may be a scam or just not really needed. doing this with a few other upgrades may cost me around 100-150. which is cheaper than a new computer, but would the performance be all that better, if what Jam says is true. He said that the boost in cpu wont really matter if i couldnt get more than 256k ram.

Dude, do you realize what you can get for $150? This is just one example:

And there are other sites that specialize in this kinda stuff:

"And that's the fishing line, because Sharkboy said so!"

lol, jesus.
no i didnt realize. always assumed it would be several hundred buks
thanks Jam
think i will prob pick something up there

Make sure to read the detailed descriptions. Stay away from "Small Form Factor" or "Desktop" units. Look for "Tower" or "Mid-tower", grade B or better.

About the MEW-VM motherboard: HP is kind of sporadic on their support for the various models using that motherboard. This:
http://forums11.itrc.hp.com/service...
shows those models. I checked a few and some had a bios update and some didn't. Of those that did only the 1.03 version was listed.
If it's got the original 810 chipset then you're limited to 100 mhz FSB. The 810E, which some of the MEW boards had, could go up to 133. If Belarc is right I think you have the original.
