CPU and RAM matching!!!!

[philkerswell]

Hi...

I have an MSI motherboard KTV4

I fitted an Athlon xp 3000+ CPU with 512 L2 cache. I've checked the labels and its definately a 333mhz chip 9not the 400mhz one)

I realised the CPU was running slow - PC Wizard says 1300 Mhz (it should be about 2100 mhz

So I installed a brand new 1Gb PC2700 333mhz DDR Ram chip...

PROBLEMS:

1 - PC Wizard identifies the RAM as

Physical Memory : 512 MB (1 x 512 DDR-SDRAM PC3200 @ 200 MHz)

2- the CPU is still rinning at 1300mhz

PLEASE - any help... if PC Wizard is right, does this mean I've been sent the wrong RAM??? It is generic RAM, with a stick-on label...

Your RAM working asynch between CPU (200 MHz). Your CPU actualy work on 100 Mhz FSB. You must find jumper on motherboard to change to 133-166 rate. After that your CPU will be recognize as 3000+ 2158 MHz (13 x 166 Mhz). You can change RAM speed in BIOS to @166 MHz but it is note required.

Good luck !

PS. It is hardware problem not general discussion

BUT...what about the RAM ???

[Guest]

the RAM is generic...no make.

the MSI website (my motherboard) says it should support up to 3Gb of 333 DDR

should I be setting the FSB to 166 mhz when I go into bios?

mmm you may be right about the memory - i'll ring their customer support tomorrow- cos if it's not showing as 1Gb it must be faulty ???

ref jumpers... my mobo does not have jumpers for the FSB... the booklet says do it in BIOS (the only jumpers are for clearing the CMOS RAM)

hi - yes did set FSB to 166 ..and the system crashed/froze and died.....

..sorry could'nt help it....

PS....one thing I've observed is the lack of talk on the multiplier.Make sure that your Multiplier is set at 6.5x (3000+Barton) with 333fsb at 166mhz , if auto is not available or on


Oh, and the actual speed reading should be 2176mhz for (3000+ Barton).


Just a tip.

Oh and one more thing:

CPU
• Supports Socket A (Socket 462) for AMD® Athlon™ XP/
Athlon™/Duron™ processor
• Supports 800MHz up to Athlon™ XP 2800+ processor

Unless there's a Bios update, seems like it stops at 2800+ !

You should definately consider flashing the bios. This may resolve all your troubles in one fell swoop. Often early revision bios's cannot support faster chips (as glinglin so wisley noted). It may help your memory problem as well to update (flash) the bios. When you finish flashing the bios be sure to tell the bios to reset all settings to defualt. This will undo anything you did in the settings while you messed around. It should set all fsb and multiplier settings back to auto detect. It should also reset the ram settings to defualt if you messed with the latency or the speed. If all does not work well when you have flashed the bios and reset to defualts I would suspect the motherboard of being screwed. This would explain your problems in terms of one faulty component (motherboard) instead of two (ram and cpu). as for manualy jumpering the motherboard to 133mhz you will find that motherboards just don't have jumpers any more. Its all done in the bios and if your having troubles you should probably leave the bios settings to defualt. It is very unlikely that they are the problem unless you changed them. Bios's defualt to the safest settings for memory timings and such. You should not change them unless you know what you are doing.

at first clear CMOS by jumper to hang up system. Go into BIOS and with defaults try again mark 166 MHz FSB. If that will still crash PC you need BIOS update. Sometime when core is scratched CPU work only on lower FSB but I suspect all is perfect.
