Duron and RAM question!

[RobUK]

I've decided to upgrade my AMD K6/2 450 to an AMD DURON 700. As the DDR is 200MHz would pc100 SDRAM work on whatever motherboard i get or would i need the pc133 SDRAM?

BTW what mobo would be the best for a DURON???

[Missing the point]

Well, prices are almost identicle for PC100 or PC133 Ram, so I would go for the 133(which is what I did for my Duron system).

I would recommend the Asus A7V W/Out Audio. That seems to be the best one for the Duron currently........

Also, I would suggest that you get the Duron 650, and save the money, and buy a nice heatsink/fan, and overclock it to 950 or more http://sysopt.earthweb.com/forum/smile.gif

If you have to buy new ram go with the PC133. As stated earlier, PC100 & PC133 prices are nearly the same (and nearly out of reach where I live), but if you've already have PC100, it'll work fine in the A7V.

I just got a Duron 650 and an ASUS A7V-WOA over the weekend and am using my old PC100 ram, and this thing is blazing fast. I've o/c'd to 750 @ 1.5v with a stocker Duron H/S & fan, and so far so good...very fast, and very stable. I'll be ordering in a better cooler soon, and see what this puppy can really do!! Any suggestions??

If you do buy 133 memory be careful and save your receipt. The "133" memory I bought at a show last week will not run in my motherboard at 133, so I'm stuck at 100 or a little bit more (maybe 106 is where other devices freeze system. The memroy has a 133 sticker on it - but Sisoft sandra reports it as pc100 (Cas2) when the module is reading what is in the memory stick. Maybe there's more to this than I realize - but having bought a lot of memory without ever having a problem I just threw out the receipt once I got it booted in auto/pci/dimm selection. I only discovered problem several days later when trying to set memory to host clock + 33.

Ralph, have you tried running your PC-133 RAM at Cas3? Typically, only good quality PC-133 RAM will actually run at this speed with the latency set at 2. When it comes to RAM, I learned the tough way, never buy cheap!

I found another stick of memory I had bought several months ago that was also labled PC133. So I put that in instead. Lo and behold sisoft sandra reports that that memory is indeed PC133 - of course at CAS3. (actually I think it reports CL3 but that's the same, right?)

Regardless of the reporting - setting either of these sticks to Host Clock + 33 (of course with CAS3) in the bios for me results in a blank screen, no boot, and the necessity to short out cmos and start over. I really wish there was a way for me to tell if its the motherboard or the memory. (Is Host clock + 33 = 133 or 233 on a Duron that's runnning 100 DDR = 200?).

Or maybe its just bios settings. Anyone out there successfully running a PCCHIPS M805lr at 133 for the memory speed????

RalphArch, I bought 3 sticks of pc133(64MB) or so I thought. I tried host clock +33, same problem. MSI K7T Pro.
