Athlon XP and PC133 memory under WinXP

[steverae]

Dropped a Athlon XP 1500+ chip into my machine :-

Iwill KK266-Raid M/B (Bios updated 22/10/01)
512 PC133 SDRAM
30 GB IBM Deskstar (Raid-0 Array)
Divx 4.11 Codec

Windows XP started fine and ran great until I tried to run VirtualDub to re-encode a Divx movie.

Everything when great (upto 79-80 fps encoding rate - Wow) then the system crashed.

This happened repeatedly with any Divx file.
Now this worked fine with my old CPU (Athlon Tbird 1.Ghz)

My question is does the Athlon XP range have to have DDR memory to work effeciantly, or is this a Win XP quirk.

I to have a XP processor, up until a few days ago running with 256mb 133Mhz mem. Had a few quirks with XP, things running slow or not running.

Changed the mem and wow, rock solid system !!

Change your mem as soon as possible it does make a difference.

You changed the memeory to what and what kind of board if you don't mind?

10 to one he changed to DDR memory--on any board running the AthyXP.

Thanks - just wondering whether it was a board that took both kinds of RAM.

thanx - though as much. have to change my board and chip - nightmare, might wait and see what the iwill xp333 board is like.

thanx again everyone.

BTW is there anything you can do with the memory timings in the bios to stablise the the system with pc133 ?

Stevie-That depends on the tweeks allowed on the board itself.
Top tier board manuf. like Asus allow you to run memory and systems at different speeds.133-133-33. 133-100=33 100-100-33--[system-memory-PCI Bus]New boards can run 66MHzPCI Bus, but the best thing to do I think if i deduce your situation properly is to try to get more through your PC133, which would mean-only if it is good ram,set the memory chip timing to 2,2,2.@133,if that doesn't work and you can do it, set 133-100-33 and go to 2-2-2- for memory chipset timing. That should give more stability-not performance-stability.
I don't know how old that IWill board is, you might want to look at a board that has the new Via*A* chipset for your rig. For price and with the reviews I've read, Soyo Dragon+ looks great, got the via *A* chipset,raid,etc and about -$60 than the Asus with the same stuff, and Soyo does make nice boards-my last one was a Soyo-very nice. See the review in Tom's hardware on the Soyo Dragon + .

cheers Spark. The board is a Via KT133A chipset.

It's a great board. I'll try what you suggest and get back to ya.

cheers

Is your board jumperless? I know with my asus a7v133 I had to set the cpu speed by jumpers to get everything stable and it worked fine... well, until the delta fan stopped working. It was not a pretty sight. ;p

i run pc-2700 OCZ CAS2 ddr, ddr is speedy and i havent had any problems like that so far with it.
