Hey guys, I am perplexed here. Venice @ 278 * 9 = 2500 mhz Corsair Value Ram 2 x 512 MB @ DDR266 = DDR 359 OC ASUS A8N SLI Premium (Flashed a deluxe) I got the vcore maxed at 1.550 (reads 1.600 in CPUz) Chipset is at 1.6v HT at 1.25v mem is stock(2.6v) Why can't I go higher? Instability sets in around 285 mhz FSB. My temps are fine; 43 load in the case prime95 torture. I have the voltage maxed out. I can get the FSB to 300 with a lower multiplier. Venice 3000+ 278 x 9 = 2500mhz A8N-SLI-Deluxe Flashed to Premium 2 x Corsiar ValueRam DDR400 @DDR266 Gigabyte 6600gt @590/1180

thats with the HT multiplier set to __ ? I remember having hit ~2550 MHz and stable (prime 95) with my 3000+ Venice on the A8N-E. That was with the HT multiplier set to 3x. Vcore was at 1.425V. I dont think you need to push the Vcore beyond 1.45V or 1.46V. Kailas Shastry 3000+ Venice, A8N-E, 768MB DDR266, 160GB Barracuda, 380W Cooler Master

I haven't looked into to it, but what did you gain by flashing a Deluxe with the Premium BIOS? I'm in agreement with Kailas...there generally isn't a need to bump the vcore up so much. And as he pointed out, you neglected to list the HT multi, but I kinda doubt that it's at 4x.

Umm... HT multiplier is at 3x. Do I have a gimp venice or something? Gonna drop the vcore to 1.45v. Hexus.net got a 3000 venice to 300 x 9 with stock voltage... Venice 3000+ 278 x 9 = 2500mhz A8N-SLI-Deluxe Flashed to Premium 2 x Corsiar ValueRam DDR400 @DDR266 Gigabyte 6600gt @590/1180

The premium bios includes voltage options for chipset and ht. Ahhh.. it won't load windows @ 1.45 volts. During the windows load screen, where the bar goes across, the monitor turned rainbow and then it went black, I'm thining instability... I must have a gimp venice then?

Oh yeah ht is at 3x Venice 3000+ 278 x 9 = 2500mhz A8N-SLI-Deluxe Flashed to Premium 2 x Corsiar ValueRam DDR400 @DDR266 Gigabyte 6600gt @590/1180

Stupid question: How do you know it is a Venice? Did you check with CPUZ / checked the part number? AFAIK, even with stock voltage of 1.4V the 3000+ venice does ~2.3GHz w/ no problem. With some luck you can gain another 50-100MHz. But to hit 2.5GHz, you need to up the Vcore just a little bit. 1.425V is what I need, and someone else may need a little higher, but not 1.55V. When we are talking of millions of transistors, however tiny, even a 0.025V is substantial. At 1.55V, I wonder what your idle temps are. Try this: In the BIOS (not PC Probe or CPUZ), what is the lowest Vcore with which you can sustain 2.5GHz? I know this is not very practical for most people, but, can you put your CPU in another board that supports overclocking and see how it (your CPU) behaves?
