o/c problems
I have a
A7N8X deluxe with 2500 Barton unlocked
PNY 512mb 3500- 1 stick
sk-7 with 80mm vantec tornado
I got it to about 2.3GHz and booted and wasnt stable so i tried backing off to i know where it was stable. So I set it at 10x200 @1.65v and 1.7v which is 2GHz. It boots fine and runs but at about 1-2 hours later it restarts, any ideas how this prob came about. I dont know what to do

Also, a slight voltage increase may be in the cards, tho I haven't used a Barton personally and can't recall offhand what they can handle.
Cpu, as stated above I haven't had or worked on a Barton. I run my TBred B @ 1.85 all day every day for 8-9 months now and know some are higher than that but not sure if it applies the same to Bartons.
My Barton does not like much more than 1.75 voltage to run best-- and .03 more is much more for a Barton. The areas around my barton core on base die are discolored, the core is more resistant to heat damage, as far as the heat dumping ability of the core containment than the surrounding die. But it still runs hyper-well. I would say without Peltier or liquid cooling, you do not want to run a Barton more than 1.78 for more than 15 minutes running, or you are likely to trash things in its overall die or card part and have the core disconnected from the rest of the die by melting. Doing this is a fire safety thing, really.

Trick when going more extreme than 2.7 or 2.8 Volts to RAM is to write down what you do, as each box is different in teh details of how it will react, and various DIMMs can act a tib different even within same brand and kind. NO QC is perfect, and OCing loads PSU more and the circuits that the mobo uses to get voltages lower than about 3 volts also, so trick is not to overload mobo cirucuits and figure out what is happening when things START to go unstable. Safest is to go slower and change one thing at a time, and see what changes where. RAM above 3.0 is EXTREME for most RAM, way overboard. Some RAM, in boxes with real good and big PSUs can run at 2.9. Most RAM will take 2.7 and 2.8 well if the PSU can handle that much power flow without starving other things too much as far as voiltage and amperage (which is primary reason for a no-boot after machine is off for a while and cool-- either something is getting no power, something is not getting enough power, or something is getting too much power OR something has internally failed). To go above 2.8 volts you get to also play with the termination voltage, frequently.

The 3 bartons I have aren't sensitive to fairly moderate vcore voltages (1.85-1.875v) and definitely overclock better at the higher vcore. The barton I presently have in my NF7-S is presently at 2400 with 1.85v vcore and is running at 40 C while folding Gromacs WUs.
Ageek, I don't know what you're talking about. Bartons come default at a HIGHER voltage than the TBred B chips, and they do just fine at 1.85v+, as do the TBred Bs...
12v = 12.4v
5v = 4.94v
3.3 = 3.296v
Vcore = 1.696v
Im not sure but i thought right now ram is relaxed im at 1:1 ratio 2,3,3,7 @ 167 frequency
FIRST though, I'd up the bios vdimm (memory voltage) to 2.8v or 2.9v with your current (faster) timings and see if it helps.
BTW, is that a rev2 Asus board? My old rev1.04 board would never run stably at 200fsb; 185 or so is the highest it can stably run due to the early stepping northbridge on it.
High end PNY is decent, the Irish folk do a good mfring job and QC (Yes, PNY's MAIN mfring facility is in Ireland). I have only had to RMA 1% of high end PNY. Ditto Crucial\Micron Technoloies RAM, Ditto good Corsair. All have good QC on mid-high quality RAM lines they mfr as brand name.
