vcore is as high as I want to go (1.45 for a REGOR X2 250) what voltage would you work with next? here are my ram timings. Perhaps that 1T Command Rate should go to 2T. This is not my sig rig but an ASUS M4A78T-E and a Anthlon X2 250 (locked multi) and I get a "core 0 failed" when stressing at 3.75 with OCCT
250 HTT and 1750 HT link
For that frequency i have to set +0.100mV to VCore and CPU-NB (my bios doesn't let me put an exact voltage, only increment +0.050 +0.100 or +0.150mV to VCore or CPU-NB voltages), and my VCore stock is 1.375V so giving it +0.100mV it goes to 1.475V and it's stable at 3.75GHz, but maybe if your bios lets you put values in small increments, maybe with 1.45V could be stable, try too incrementing NB and/or CPU-NB voltages to leave it stable...

Also for stabilize your oc change your HT-Link to stay near 2000MHz if you could, set it at x8 (1600MHz) for giving a final frequency of 2000MHz, and for the NB Frequency also change multiplier for go to 2400-2500MHz or less...

Temps for me stay at safe values under 60ºC, but my cooler isn't very good and temps go a little high...

Jaq and alli, should I follow standard OC procedure and just work one voltage change at a time or perhaps bump vcore, NB 1.8, NB-cpu, DRAM,SB all just a little. My ASUS BIOS lets me bump all of these if I want.

I can hit 3.6 stable with just the inital changes you first posted and keep ram at 1T, so 3.6 is not a problem in any way, its just going higher and it's not temp related, RAM timings pretty loose arent they?

This is a 32-bit XP run.

PCCstudent, I would seriously consider changing the command rate from 1T to 2T. That should allow the memory to run a little bit smoother during testing. Your memory is actually pretty loose. I believe stock it calls for 8-8-8-24 at 1.5volts. Perhaps you're getting close to the limits of your Athlon processor? 3.6Ghz is nothing to be ashamed of...that is for sure

Good luck

I've not pushed vcore over 1.425v, but my board is junk anyway, try 2t command rate on the memory, and try pushing it a bit harder, you should be able to get more from a 250 than I can on a 240.

I'm now testing my Regor at 3.7GHz with a similar configuration that Platinum posted at beginning of the thread, and by the moment it looks stable (need to pass a few more hours of Prime95), but if looks fine...

My actual settings are:
-HTT: 247MHz
-PCI-e: 100MHz
-VCore: +0.050mV (1.424V)
-HT Link: 1600MHz (x10) (final frequency: 1976MHz, for being below stock 2000MHz)
-NB Frequency: Auto (x10) (final frequency: 2470Mhz, for not to go too much over 2400MHz (like is recommended in much places), because in my BIOS i can't change NB Multiplier)
-RAM: 800MHz Vdimm 2.0V (final frequency: 988MHz 5-5-5-18-24 2.0V)
-CPU Configuration: all settings like Cool&Quiet, C1E, Secure Virtual Machine... Disabled

Max temps are nearly the same that before, when i oc'ed at 3.6GHz with VCore stock: 53ºC CPU - 39ºC Cores 1&2 - 34ºC motherboard, at full load stress with Prime95 with an ambient temp of 20ºC

Well, if i see it's stable a few more hours, i like Platinum change my settings in the first page settings score...

Happy Christmas to everyone!!!

P.D.: sorry if i wrote something wrong, my english isn't very good...

Edited: not stable, and for giving more voltaje, i could do 3.75GHz upping VCore +0.100mV and CPU-NB Voltage +0.100mV too, but temps go so high... I stay at 3.6GHz!!!

Jacqlittle, at 2470Mhz NB Frequency how much cpu-nb voltage are you using? That component may need a slight bump in voltage. If anything try lowering your NB Frequency and re-run the stress test at 247Mhz.

Keep us updated

Good luck

Now I've pushed vcore to 1.45v, slowed memory timings to 5-5-5-16-20 and I'm orthos testing at 256 FSB, 3580Mhz

First pass 1024k passed - woot!
