cpu fsb memory chip set old laptop

kleinde66 · 02-14-2023, 07:58 PM

good day everyone
i have an old laptop i'v been messing with.

Code:

Mobo: Acer model: Poyang v: V1.45 
Intel Mobile GM965/GL960 Integrated Graphics

i have up graded the cpu to Intel Core2 Duo T7700 with 800 fsb.
i upgraded the memory to pc2-6400 800mhz and that gave me sinking issues.
so i put thee old 667 memory back in and it worked.

so is my fsb 667mhz or 800mhz ?

any wisdom will be appreciated

The fsb is determined by the motherboard not the cpu. My guess is the ram it came with is the max that the motherboard can handle so I say your fsb is 667mhz. Unless the motherboard bios setup allows you to change that(doubtful), you are probably stuck there.

These days, Rule #1 of hardware repair is: "If it works, don't fix it!" I hereby declare you in flagrant breach of rule #1, and responsible for all consequences.

Seriously, don't mess with old laptops. Everything is inclined to be interdependent so an apparently kosher switch like the one you just did can have unintended consequences, like too much current on a particular pin. Fine if it's kill or cure, and you'll accept 'killed' as a result. But if that upsets you, stay clear.

BTW. 667Mhz was a common figure for FSBs back in the day.

true business_kid
but i have a few of these and they work well i was hopping for 800 fsb but it works well at 667 fsb.
the chip set is good for 800 fsb with the exception:

Code:

DDR2-800 with any Speed Bin Timing combination other then 5-5-5 or 6-6-6

i'm having problems finding the timing of the pc2-6400 memory i have.

this one is dull booted with cbpp11 and arcolinux and runs both well.

you just can't edit big pic's or movies.

Hmmm. They were up at about 40nm lithography, and timing was all over the place. The hardware guy's way to do it is to get the part number, usually the longest & biggest typeface alphanumeric string on each chip, and search for '<part number> +data' Download the pdf of the datasheet which should give timing & access times.

Back in the day, manufacturers used to print 1000s of databooks,and give them free gratis to R&D departments. Then some guy scanned the those databooks and put them online as pdfs. FINALLY,manufacturers copped on and got their datasheets up on their own websites.

kleinde66 · 02-16-2023, 04:13 PM

i called a-tech and they were no help, guy told me they don't do that what ever that means. could not tell me what the timing is. the only way to see the chips on the memory is to remove the sticker that says do not remove lol i might send it back for a refund.

business_kid · 02-17-2023, 04:54 AM

Don't call anyone.Get the part number and grab the datasheet. If you can't settle on the part number, post a link to the biggest in-focus photo of the writing on a black silicon chip, and I'll guess it for you.

EDIT: This is the early 2000s vintage, so the graphics will suck. It probably will beat a RazPi but not convincingly. Is it worth all this effort or are you just farting about?

My iMac uses the same chipset and CPU, but ATI graphics:

Code:

I think the GM965 chipset is what is responsible for limiting RAM speed to 667, which is what MacOS also reports.

the chips are new i have included an pic of the chips at the bottom.

Re the chips: I can see the labels, and you'll get results just typing

Code:

pc2-6400 so dimm +spec

They range from 500MHz - 800MHz, the most common being 667 MHz.

The actual chips I was talking about were the 8 pieces of black plastic with loads of legs soldered onto the little pcb . They are just visible under the label. Never Mind. Look yours up.

i'm closing this thread, i have gone back and i can't find the pdf that had (DDR2-800 with any Speed Bin Timing combination other then 5-5-5 or 6-6-6) in it.
