help w/ ibm netvista

[fritoking]

ok , first time posting here. I have an ibm netvista 6792 - e4u that was free. I want to upgrade the cpu for the kids to play on. I have looked al over the ibm/lenovo site and cannot find a supported cpu list. right now its runing a p4 willamette 1.6 ghz socket 478. i realize that its a pooch by todays standards , i just thought if i can throw 25 to 50 bux in it it would make a good pc for the kids.Its actually pretty snappy for general use. the main board is an ibm w/ intel i845 rev. a3 chipset. southbridge intel 82801ba(ich2), 512 mb pc133 sdram . any ideas of processor support? thanks for any help

By the looks of it, you'll only be able to put Willamette core CPUs into it; PC133 RAM is SDRAM, and I doubt that Northwood CPUs or higher would support it, due to the quad-pumped FSB.
If you can find a spare Northwood CPU then you could try that, just to see if it works.
If it doesn't, then the fastest Willamette CPU that has been made it 2 GHz.
My advice would be to upgrade the RAM to 768 MB or 1 GB, and (if you can), overclock that CPU!

well i thought about that...but looking thru the bios i see no way to oc it?

Ok, its probably been locked. Download CPU-Z (if you dont already have it) from here: http://www.cpuid.com/cpuz.php
Then run it and prinscreen the motherboard, RAM, and CPU specs; from there you can find out what CPUs are compatible with your motherboard.

In those oem pc bioses you cannot change anything and even if you were to upgrade the cpu you wouldn't see much difference.

You have two option, upgrade the ram and leave with it or buy a new pc for you kids.

I agree with Fastmix, although you could probably get a bit of money if you sold the IBM which would help pay for a more upgradeable PC.
If you can't afford that, then buy more RAM for it, and if you're putting XP on it then consider a program called nLite: it allows you to cut out all unwanted and unnecesarry features, making it smaller and faster.

Willamette uses a quad pumped FSB as well. They overclock really poorly. DDR, DDR2, DDR3 etc are all SDRAM as well.
I do believe the i845 supports Northwoods, your best bet is getting one of those and some extra RAM. Don't expect miracles though, and don't invest too much as it isn't really worth it anymore.

Yeah, Pentium 4 systems are too old to be of any use except for what you're using it for; a kids PC.
However, there is a difference between SDRAM and DDR-SDRAM; DDR has a double-pumped bus, which gives twice the bandwidth of SDRAM. Also, the modules have different pin counts (168 compared to 182 for DDR).
So even if you get a Northwood P4 working in it, you'll probably have a huge bottleneck in the RAM.

thanks for all the replies guys...still not 100 % sure what im going to do..lol

Hopefully its not too late for a reply...
Your free system will FOR SURE support up to a 2.2Ghz Northwood 400Mhz FSB processor.
See here:

If whoever bought it had ordered it configured that way it would have been a 6792-45U or 6792-43U. SO FOR SURE (As long as you update the BIOS) it can support that processor.

Beyond that its speculation; you could call Lenovo and ask them for the Maximum processor that - that system can support.

I dug through the BIOS & it has been updated to support ALL Northwood steppings. Here are the Release notes for that:
ftp://ftp.software.ibm.com/pc/pccbbs/netvista_bios/20jt46a.txt

HOWEVER, that doesn't mean its a guarantee that it will support faster than 2.2Ghz but its possible.

SO FOR SURE 2.2Ghz, 400Mhz FSB, 512KB L2 Cache:

If you plug the S-Spec codes into ebay you can find an affordable version... There are Nine different S-SPecs so i'd keep looking until you find one that's really cheap.

I did a look around, unfortunately your plain "Intel 845" chipset is very limited. The 845 E & G etc opened up a lot more processors but SOME plain "INTEL 845" Chipsets list support up to 2.4 & 2.6Ghz (400FSB) so ??? if you are a gambler you might get lucky although the difference between 2.2 & 2.4/2.6 is pretty small. WHO knows you may be even have support for up to the OEM 2.8Ghz 400Mhz FSB (S-Spec code: SL7EY) or 3.0Ghz 400FSB. If you have a Craiglist in your city you might try putting an add asking for someone with a 2.4Ghz -, 2.5, 2.6, 2.8, - 3.0Ghz with a 400Mhz FSB to see if you can try before you buy kind of arrangement.

Years back i bought a powerleap adapter & turned my limited Dell Dimension 8100 1.4Ghz Willamette with a 423 pin chipset into a 478...and dropped in a 2.8Ghz 400Mhz (SL7EY). The Bios doesn't properly detect it at 2.8Ghz...rather it shows up as a 1.6Ghz, however windows sees it and operates it correctly at 2.8Ghz. So who knows what that motherboard will truly support unless they've tried it. Just make sure you have the latest BIOS. That system still runs great as a media PC, server, TV recorder, and media streamer, and HD file player. (it uses RDRAM 800 vs urs with SDRAM)

One last comment. These types of systems are hardly obsolete. I buy up these systems from Universities & corporations liquidating to make room for upgrades and i clean / them fix anything that's broken and resell or donate them. For 85% of the population they have plenty of features & use. They do internet, movies, even HD movies, operate as Media PC's, play-burn-store music, or act as in home servers, word process, and run business spreadsheets/powerpoint etc...
With a decent enough AGP graphics card available for a few bucks...with performance equivalent to 9800-x800XT they will play older games and ALL those kids games. So they FAR from obsolete! I even find people who have good uses for PIII's and PII's. Smoothwall routers, media file sharers, juke boxes blah blah blah.

EDIT:
I Forgot that i have this ALL-In-One IBM NetVista 6274 which has the same motherboard "Intel 845" - 400Mhz FSB only... It is running a 2.4Ghz 400Mhz FSB Celery processor. I just threw it in to test out, after i got the replacement Goofy IBM heatsink, whether the system booted. It was a few months back & then set the system aside after i loaded xp. (it was a University PC that someone robbed some parts, including CPU & heatsink). It even let me flash the BIOS without fully recognizing the 2.4Ghz Celeron (until after it was Flashed). (I'm keeping it more as a novelty PC as its got the 15" LCD monitor & CD/DVD drive built right into one frame)...
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-41199
As you can see this processor came with even slower processors ... i think the fastest it came from IBM with was a 1.9Ghz...So add that to ur knowledge base. If i find a bargain on another SL7EY or ....i'll give it a try. GOOD LUCK!

hey,

I know it's a VERY old thred, but it's the only one I found on this MB...

can anyone tell me where I can find the manual for it?

I'v got one of those, or a very similar one, and i don't know where the power switch cable, reset and so on goes, and the comp. start by it self as soon as i plug in the power
