Hi
I am thinking of upgrading my cpu/mobo to an Asus P4P800S/P4 3.2GHz. This board takes PC3200 DDR RAM and I have PC2100 sticks in my Epox board. Can I use PC2100 RAM (for the time being) in the Asus board and what will the effect be on performance? Presumably lower, but by how much? Or is it not worth bothering and I should replace the RAM also?
TIA

The motherboard specs are here - http://shop.ncix.com/products/index.php?sku=10312&vpn=P4P800S-UAY which says

Quote:
Memory
- 2 x 184-pin DIMM Sockets support max. 2GB
- PC3200/PC2700/PC2100 non-ECC DDR SDRAM memory

But a message on the forums by DawnTreader says

Quote:
if you get this board you might want to be sure to get RAM that is 400Mhz. i seem to be having a problem, occasionally with windows XP complaining that the RPC remote procedure call keeps failing in some way and needs to reboot the system. i have 2 machines that i put together with 333 RAM and both have given me this message. i reinstalled one from scratch and thought the problem was gone, but when i installed the second machine it did the same thing as the first install on the first machine. hoping a second reinstall on the second machine will clear it, but, i dont trust this board and the 333Mhz Infineon RAM that i put with it. here's hoping. :(

PC2100 is 266MHz, PC2700 is 333MHz, PC3200 is 400MHz.

Thank you for your informative reply John. However, the details of RAM are a complete mystery to me.
For instance, look here so which one do I go for to go in the Asus board? The descriptions are gobbleydegook to me so which is the right one please?
Thank you again
John

i found that using the tester software on www.crucial.com site http://www.crucial.com/systemscanner picked out exactly what ram worked on all machines i tested it on.

One other question if I may.
Crucial give the price of a 1GB stick as £185. and a 512GB as £62.00. Why is the 1GB more than the price of 2x512GB? And is there any reason to have one where 2 will do the same job?
Thanks
John

The 1GB stick will only take up one slot, allowing room for further upgrades in the future. Why does it cost so much more? Convenience at having all that memory in the same size stick.

AFAIK, 2x512GB sticks (I think you meant 2.512MB) will work just as well but use up more slots.

P.S. If this info is totally wrong forgive me for not reading the whole thread in full.

Hi Chirpy
Thanks for that but I thought there was more to it than just the convenience of having 1GB in 1 stick as against 2 sticks. 2x512MB =£124.52 and 1GB = £185.64. That's a lot of difference for the convenience IMO.
Thanks again

But if you only have a limited number of RAM chip slots in your motherboard (3, I think) then if you have 512Mb chips you can only get 1.5Gb on your board, but the motherboard specs say you can have up to 2Gb. The illustration isn't that clear - there may only be 2 memory slots.

It's more than just cost.

Hi John,

I just applied the same principle when you buy a memory card for a camera or a new hard drive. Even though you pay for one twice as powerful, the cost is usually more than double because for example with a hard drive, a 200GB drive will take up half the space of 2x100GB drives. Therefore allowing you to install another large drive in the spare slot at a later date. Otherwise you'd have to remove one of the 100GB drives to make room for a larger one.

I would guess that the reason is probably economical. RAM is looked at as a commodity really. 512MB sticks are much more widely used so more will be produced.

Hi, from the US of A

You Should look at ABIT boards and DUAL CHANNEL
memory.. dual channel memory can be the memory you have,It DOUBLES your Memory buss speed ...you can buy dual channel memory which is setup that way,and you can use what you have,still works! I have two 256 meg chips and one 512 meg(1 gig)

I have a AN7 ABIT motherboard with TWO Maxtor 130 Gig SATA 7200 rpm and a ATA100 100 gig Maxtor!
The two maxtor SATA are on the Raid side and are NOT setup as Raid,just normal drive setup! speed as tested. using Sandra 4 20 meg ATA. 49 meg SATA....over TWICE the speed of the ATA.
The MB only has two SATA ports!
AMD 3000 xp 333 fsb ...ASUS Dual AGP/digital 5700 with S-video port 256 meg DDR 2 memory
Audigy plat-2 /EX...6.1 sound
BUT it has onboard POST ..has 8 V2 USB 2 inside.
Firewire port back and inside. 6 channel sound SpdF digital internal in/out...
runs like a clock! check it out Http://www.abit.com

I have a SONY trv-310 Digital . A new Pacific Digital DVD 2500 firmware upgraded to the 2510 (LAYERED DVD ) EIGHT GIG of room.It seems one CAN up the firmware and have the drive run this way!
Problem is one cannot buy the DVD layered disks yet!

And here is a tit bit.. I found what was causing
the AV/C Subunit problem a couple of years ago,and I remit it here as it happened to me again, It had to do with the INI and PNF file MSDV.INI and MSDV.PNF in the Windows INI directory had been CHANGED by the addition of a .1 on the end,this stopped the file from being activated..renaming both files corrected the problem. somehow some files were being modified with this,and some did not,meaning they worked fine.I think an added video program was the cause of this,Which one,anybodys guess!
Cheers from a Kiwibird living in the SanFranciscio area.
