A7N8X Rev2 & AMD3200 fsb problems

[Dave]

If I set the RAM memory to 200MHz - that works, with CPU at 166 X11. I
am now up to 185MHz CPU and RAM 100%

 

[Doug Ramage]

Sounds like you bought the 333mhz version of the 3200+!

According to AMD's website, there is only one version of an XP3200 and it
runs at 400Mhz.

There are 2 versions of the XP3000 - 333Mhz and 400Mhz.

 

[Doug Ramage]

Neither module will work at 200Mhz FSB. The first pass on memtest86
brought up one fail address 00004f5fd60 79.9mb. Again, is it really
the RAM or may it be the CPU or motherboard?

Asus do a utility that allows you to raise the FSB and adjust the RAM
timings from within Windows, without re-booting.

I boot into Windows XP Pro at 166 FSB, and ramp it up, if I want.

He did claim to have an A7N8X REV 2

Not sure what I was saying - thought you said he had a 166MHz Board.

but I think AMD does make a 333 version of the 3200+.

Well if you care to find me one for sale, or a link on AMDs website...

I only had one fail error on my RAM...it showed up immediately when memtest
started. I never suspected the RAM till that showed up. My advice..contact
the original point of purchase or OCZ. You should have 30 days from the
retailer and lifetime from OCZ. If I can run a 2500 at 3200 on almost a twin
setup here...there is no reason for you not to be able to. Make sure to
mention to both that it is a matched dual channel set of RAM. They should
replace the pair..though it really doesn't seem to matter.

It could be either. And to make matters worse, they might both be OK,
but they just don't work together well at that frequency. Thus, if you
took a random selection of 10 MOBO's and 10 memory sticks, you might
find 8 or 9 combinations that work together, and some that just won't
work at all.

Just to be awkward...

but it still means he almost certainly doesn't have one.

simply put, more voltage is required

Tried these settings, saved and exited and PC didn't reboot. Turned PC
off and reset to Default Settings and then tried again with your
settings. Then got Speech Post Reporter telling me "System fail memory
test" and wouldn't boot at all. PC got stuck and wouldn't reboot -
took out RAM modules. Cleared CMOS and put back my old Crucial PC2700
RAM with fsb at 166.

So is the expensive OCZ RAM at fault or is it my mobo?

Well, I've returned the OCZ RAM and now have Crucial RAM - exact same
problem - so it must be the motherboard?

 

[Dr Teeth]

I was under the impression AMD didn't make a 333MHz 3200+.

Hi Ben,

They made a batch of OEM ones for HP.

Just in case anyone is still interested!... I replaced the CPU and
everything is working as it should. Thanks for all your help and
advice.
