Ok well ive made it up to 1 hour at prime 95 before i get a blue screen and windows resets!!
Normally the program gives me the rounding error but a bsod means i need to give the cpu more voltage?
Im at 217x12 for 2.6 ghz on a 3400+ dfi
2.6 ghz is completely stable at 1.550 volts but as soon as i bump fsb up to 220 i can only pass 1 hour prime then bsod.

any help appreciated

also do newcastle 3400's crap out aruond 2600 mhz?
im using a xp90 with zalman fan
46 idle, 62 load

There's your problem. lower the FSB or set it to a normal one... most mobos do not have pci/agp clocklocks.
 
this is a dfi s754 lanparty
so it does have agp pci locks.
socket 754's run hotter than 939's?
or this is what i am led to believe.
ive tried reseatin the heatsink 20 times and flashin the bios 5 times.
i think the s754 just runs hot as hell.

damn 220 fsb is too much huh, i guess u learn new stuff everyday

edit i can run 220 fsb now, but i have to run at 3x ht
is this gonna affect performance?
and i have to go to 2t timing.
so 215 is still good with 1t but 220 needs 2t.
this shit is confusing, i think im gonna take a nap

No. You'll never notice it.

This will affect performance. Not worth 5MHz FSB.
 
ok im gonna stay at 2.55 ghz so i can keep it at 1.5 volts.
i see no difference from stock (2.4) and oced 2.6 ghz, but damn i guess 2.7 is one goal i will never see
:(

and how big of a performance loss are we talking about, i know s754's are not dual channel and only single so can performance loss be that great?
 
It's not going to make you run like a Pentium 2, but it's great enough that 5MHz isn't worth it IMO
 
im gonna run it at stock voltage
i can get another 100 mhz on it but the temperatures are still sky high, but it never crashes.
i have it set to shutdown at 70 degrees but that hasnt happened yet
