New Athlon 1700+

I just put together an Abit KG7-Raid with 512 megs Crucial Pc2100 RAM and an AthlonXP 1700+. I bought these parts to replace my existing cpu and motherboard(i had an old slot athlon 650). The problem is that for some reason under this new hardware the system only runs reliably UNDERCLOCKED to 1100 mhz, when the XP should be at 1466. to accomplish this underclock the bus is at 100mhz instead of 133. At 1100 mhz it runs ok, but i still cant cold reboot the machine, it has to be turned off and on. My only guess as to why this is happening is that im running the same older 300watt PowerMan power supply that i had previously. Are these the symptoms of insufficient power? or do i have some other problem?

P.s. this system does also run 1 cdrw, 1 dvd-rom, 2 harddrives, and a geforce256 DDR.

one word...
enermax.

i feel your pain.

Why do i feel like the lone sane voice in the mental assylum?

ok, I tried unplugging all cdroms and pci cards, and booting on just a voodoo3 and 1 harddrive, with this setup i was into windows at a bus speed of around 120 mhz, however unstablely (it froze the minute i started a cpu stressing program). Once in windows i was able to cold restart as well. Is this confirmation of a power issue? i hope so

Not really confirmation. At 120 mhz you are now overclocking the PCI and AGP buses which adds more variables to your problem. At 133mhz the PCI and AGP dividers change and keep both buses at specification.

With all the extras removed, conserving some power, I was trying to determine if the system is stable at 133mhz.

the pci bus was not over clocked cause i can control the dividers on my board. I had changed the fsb ratio from 3:3:1 to 4:4:1 (cpu:SDRAMci) to aviod this.
Another odd thing i noticed was that with every thing in i CAN boot to windows at 120(4:4:1) so it would seem i cant do any better with everything taken out than with everything left in... somone shoot me please

i was looking at psu's what do you guys think of

EG365P-VE, which is thier 350 watt one price around 47
EG465P-VE, which is thier 430 watt one price around 79

you can check em here http://www.enermax.com.tw/products/switch-main.htm

Hey I am having the same problem with an XP 1600+ with a Gigabyte GA 7DXR with bios version F7. I have a 400 watt power supply.

The computer boots up at 100 fsb instead of the 133 fsb. I can adjust the fsb in bios up to 120, but thats it. I sent the chip back in case of a defect. I am running a duron 750 oced to 824 right now, and cpu temps are at 49 deg C under full load. So I don't think heat is the problem.

Do you set your jumper to 133 fsb?
Most socket A motherboards come with default 100 fsb setting.

Hmmm, same chipset, same problem. This sounds familiar. I think someone posted message about about lowering the DRAM voltage. I'm searching the forums now...

IcoolerthnU,

Enermax PSUs are great. (I have the predecessor to the EG365P-VE). As long as you are keeping the Geforce256 you are better off with the 430 watter, though. Plus, it gives you more headroom for system expansion.

As for your problem, before you invest more money take a look at <A HREF="http://www.viahardware.com/faq/kg7kr7/kg7kr7faq.htm" target="_new">Paul's Unofficial Abit KG7-RAID and KR7A-RAID FAQ</A>, specifically the <A HREF="http://www.viahardware.com/faq/kg7kr7/instabilities.htm" target="_new">instability page</A>.

Lepp,

You may want to take a look at the instability page for ideas, as well.

Just out of Curiosity....do you have the LATEST Bios for your KG7-RAID ?!?

Some Computer Shops of Boards that sit there for awhiel that arent sold....still good, but they have an older BIOS on it....

Go <b><A HREF="http://www.abit-usa.com/eng/download/bios/bios-kg7.htm" target="_new"> Here </A></b> and download the latest Bios for your board, because I know soem boards with older bios's recognize the Athlon XP but dont work 100% correctly with them without a proper Bios.......

Try it, see if it works =)

I don't know about this idea that "the BIOS sees the 133 chip" issue. Every 133 Athlon I have built always boots with the the default 100mhz speed. I then have to manually change it through either a BIOS setting or by moving jumpers to default to the 133 speed.

Check it out closely or build another system, you will get the same results.

I doubt there was anything wrong with the chip you sent back.

P.S. I'm not flaming you, I am trying to help you out for when you receive the replacement chip.

That is an example of what we like to call FFF (Fugger Fabricated Facts). The "underclocking to get stable" story is not common at all.

AMD technology + Intel technology = Intel/AMD Pentathlon IV; the <b>ULTIMATE</b> PC processor

Sounds to me like the RAM is PC1600 only not PC2100.

hey did you get your cpu in? if so hows it worken?
I put on order the enermax EG365P-VE psu thats on the amd site, it was only 47 and its 350 watt an certified. Im wondering if you were able to get it to go with a new cpu, cause if mine dont work next week when the psu comes in ill have to send mine back too. I did notice that if i up the voltage on the cpu i can get 124 mhz bus and still be stable, thou im like 41 degrees C at idle and like 50 at full load. The ram didnt have to be volted up to do 124 so im thinking the ram is good.

dude on my board you can control the ratios, the pci bus is not overclocked. i said it somewhere on one of my previous posts

Hey I haven't got it in yet, it is suppose to arrive Wednesday, but it will be this weekend until I can mess with it. I found one clue, I noticed in my bios the default cas lat for my memory is at 2 instead of 2.5. I am not sure if this will effect it. I also read that on my motherboard I should set the voltage from the default setting to 2.7 or as close as possible. Hope this helps you in some way.

Hey I got it in. I set my cas lag to 2.5 and set the system to 133 and it booted up at 1.4 mhz

Hope this helps ya, check your memoy settings.
