Can somebody please help me as I do not know computers in great enough detail. I have bought a Biostar M7NCD Pro motherboard, 2x512Mb DDR PC2700 RAM and an Althlon XP 2600+ (FSB 333MHz). As it says in the manual the motherboard supports FSB speeds upto 400MHz and DDR400, I thought it would have no trouble running the processor and RAM i bought at 333MHz. But the BIOS set the FSB Frequency to 133 (I thought it might have been the manifacture default settings), so I changed it to 166. When i start my computer up, it runs fine for a few minutes, but then Windows just freezes and i have to manually reset it.

It happens everytime i try to set FSB to 166, but it runs fine at 133. I do not understand why it won't run at 166 if it says it supports 200.

Does anybody know where i can find the solutions to this prolem please.

Thank you.

- Provide us with these BIOS settings:

DRAM voltage regulator

Memory frequency

CAS Latency
T(RAS)
T(RCD)
T(RP)

- Brand and model of memory modules, if possible.

- Probably the case that you'll have to manually increase the DRAM voltage and/or timings (CAS Latency - T(RAS) - T(RCD) - T(RP)) a bit. Memory frequency at 100 percent (sync).

It's Crucial Technology 2 x 512Mb 184Pin DIMM PC2700 DDR RAM Non-parity CL2.5 Non-machine specific.

Memory frequency - (quote) "By SPD"
CAS Lat - 2.5
T(Ras) - 7
T(RCD) - 3
T(RP) - 3

I don't know where I can find the DRam voltage regulator, hope it helps.

Thanks.

Set Memory Frequency to 100 percent.

There should be a bios setting in the voltage section relating to the memory voltage. I think it's called "DIMM voltage control" or something to that effect. May need to bump that up a bit. Set it to 2.6V if it's below that value. Could need more voltage than that but it would be better for Crucial to recommend a value as they know best their memory modules.

I'm not familiar with the said memory module and the timings you gave is exactly what i would've tried. Try to get in contact with Crucial and ask them which memory timings and voltage they would suggest for this motherboard and memory.

Also, the <b>CPU Interface</b> and <b>FSB Spread Spectrum</b> BIOS settings may have an effect on stability. It's hard for me to say at this time because i'm still trying to read up on them. There's some information on these settings in <A HREF="http://www.rojakpot.com/freebog.aspx" target="_new">Rojak's BIOS optimization guide</A> and/or the motherboard's BIOS docs (downloadable from Biostar website).

- It appears that <A HREF="http://www.crucial.com" target="_new">Crucial</A> provides a way to chat online with one of their experts. Probably want to check that out. On the left side of Crucial's website you'll see a vertical list of memory frequencies (PC3200, PC2700, etc.). Click on PC2700. Then when the next page comes up select "Live help!". I'm sorry I couldn't be much help but hopefully i've pointed you in the right direction.

Thanks a lot for your help, I will try those out and see how it goes. Just was wondering is there any possibility of it not being RAM problem? If yes, what could it be?

Cheers

Let's set the CPU voltage to 1.65V, if not at that value already. Then there's chipset voltage; not sure exactly what this would be called in the BIOS: IGP voltage (from a review i've managed to get my hands on) or something like that. Maybe increasing that a bit will help; but i'm really only guessing here. Keep AGP voltage at default. Um, we can also check to make sure the cpu temperature is not too high when running at 333MHz FSB. The BIOS should have some sort of hardware monitoring section that contains the temp information.

Reply to Prof133

well, the CPU temp is below 70C when running at 333, at least that's the temp it held before it crashes ( i think the highest it got upto was after i ran the benchmarking software at 333MHz and it was something like 65C-66C) The DRam voltage was set at 2.5 and i changed that to 2.6 it made it run at 333 for longer than before. I haven't tried the CPU nore IGP voltages yet, am gonna give them a go and see what happens.

Cheers

I tried setting my CPU Voltage to 1.65, from "default" (whatever value that is) and nothing, it still freezes and does nothing, I have the standard fan that came with processor so i don't think overheating is in question as the processor was meant to run at 333 and the fan i assume is meant to cool the processor at that speed. Have checked the Crucial website, and chated for a minute with an expert he game me a number i can ring up and sugesteed to update my BIOS, but i am not sure if i need to do that, i bought my motherboard a couple of weeks ago. If i do need to update it, how do i do it and can i do it from windows as am not very familiar with Cprompt.

cheers.

Reply to ComradeMishkin

Temps look high but it seems we've made some progress by increasing dram voltage. Give it 2.7V or 2.75V (not sure if these values void some kind of a warranty). May have to increase the memory timings (CAS Latency, etc.) an increment also. We're basically just testing here.

Looks to be some BIOS update information at the <A HREF="http://www.biostar.com.tw/support/bios/index.php3" target="_new">Biostar Website</A>.

Reply to Prof133

I have been replied to by tech support from Biostar and they sent me an update file for my BIOS, said it might help so gonna give it a shot. By the way, is there anything i shgould be aware of or carefull about when updating BIOS? I have this "BIOS updating utility" in my BIOS and not sure if i should use that to any other way, like copy the file (extention .bfp) sent to me on a floppy and then run it in that utilty.

Thanks a lot.

According to their website your motherboard supports the Biostar WinFlasher utility. This should make things easier. On <A HREF="http://www.biostar.com.tw/products/mainboard/board.php3?name=M7NCD Pro#" target="_new">this page</A>, click on the "WinFlasher" picture under "Special features" for details. Did they mention WinFlasher when you contacted them? Double-check with them.

Reply to Prof133

Well, I updated the BIOS and it seemed to have done the trick, it even says (when it starts up) that it supports FSB333.

Thank you for the help, much appriciated.

Cheers

Glad to hear it! Enjoy! ;)
