Help me push my 3000+ Venice on an A8n-E

[AznKwaiJai]

I recently got some G.Skill HZ so I took advantage of the extra room. If anyone can help me get more from this, please tell me. I would love to get 2.8Ghz. I have a A8N-E mobo
The temp is actually 55degrees durng prime. I should swap the zalman or reseat it, but what else can I do? http://img85.imageshack.us/img85/1605/oc20ve.jpg For more comp info, it is in the sig.

Anyone?

The CPU will probably top out around 2.4-2.5GHz. Limit Vcore to 1.55V.

Oh, ummm... I made a screenshot of what I got. 2.6Ghz ish at 1.525V set in bios. So possibly it might go further.

You may want to check out the A8N-E thread here.

I actually just replaced my A8N-E with an A8N32 SLI Deluxe.

 

[AznKwaiJai]

I have done that. I learned what I can already. That is how I got this far. So anyone got words of wisdom to help me push it?

 

[AznKwaiJai]

That's it? I'm stuck with only a 46% increase? I'm sure someone can help me do more.

I don't think you have that bad of an overclock.

 

[AznKwaiJai]

...but it can get better right?

 

[Amaroque]

Just out of curiosity, have you tested stability so far with Prime95? I can boot WinXP at 3GHz but it's not Prime stable.

You have a very good overclock rite now. Statistically, you aren't going to get much, if any more out of that CPU. I think that's why people aren't replying...

 

[AznKwaiJai]

Why won't people ever click my links!!! Yes, I primed it for about 11hrs. I hear that there is more to get for free, but I am having a hard time adding those htt after 192.

You have a good CPU... But you aren't going to get any more w/o raising voltages, and increasing cooling ect...

If you want the max CPU freq lower the HTT to 3 or 4, drop the mem to 100 or 133MHz, and raise the FSB as high as it will go. You will also need to increase CPU voltage. Hope that helps...

You're complaining about a 45% stable overclock?
You should be impressed - not upset..

But if you want to go further, keep this in mind as I have the same board as you and I believe the memory divider is th same for your processor:

Divider 333:
Your memory speed will be equal to CPU divided by 11
eg. So if you want your memory to run at DDR400 (assuming your mem is DDR400), then you can push it to 2200 MHz safely. If you want to experiment with OC-ing the memory, you can keep pushing up the HTT (fsb)
eg. 2200 / 11 = 200 MHz (ddr400)
2200 = 244 fsb x 9 Multiplier

Divider 266:
Your memory speed will be equal to CPU divided by 14
eg. 2800 / 14 = 200 MHz (ddr400)
2800 = 311 fsb x 9 Multiplier

Divider 200:
Memory Speed = CPU/18

IMO, anything above 1.50V is pushing the CPU too hard; the temperature will go up. I always prefer temps to be lower, because I had to deal with SocketA Athlons that used to idle at 50C...

Try to push your memory to DDR450 which would be a 225 MHz speed, as per CPU-Z read out.

I'm pushing 2.60 GHz on an Opteron 144 (1.80 GHz stock) at 1.40 to 1.4125 v on air.

Lower your HT Link Multiplier to 4x for any HTT (FSB) settings 250 or below.
Anything above 250, lower the HT Link Multi to 3x.

Depending on what ram you have, you could OC both the CPU and RAM at the same time at respectable levels.

I'm running my DDR400 memory at DDR473, and I have the same board as you, Asus A8N-E.

Here's my settings which might help:

HTT (fsb) = 289
Multiplier = 9x
HT Link Multiplier = 3x
Memory Divider = 333 (1:0.83)
Memory Timings = 2.5-3-2-5 * 1T (these are tight timings - depending on your ram you might have to relax them)
DDR VCore = 2.80V
CPU VCore = 1.4125
PCI Clock Freq = 100 MHz
PCI Clock Sync = 33.33 MHz

My effective CPU Speed = 2.60 GHz
My effective DDR Speed = 473 (236.5 per CPU-Z readout)
Temperatures Idle/Load = 29/38

Thanks for your info. The ram itself is confusing me on how far it can be pushed. Since when I drop the multiplier it goes to 270 easily, but when I have the mutiplier at 9 and the divider at 266 it won't go.
I'm also worried about my psu. On cpu-z it shows my voltage on teh cpu jumpy. I use the stock psu that came with my sonataII. I'll replace my heatsink before I do anything else, then I'll try again.
My settings are:

HTT (fsb) = 292
Multiplier = 9x
HT Link Multiplier = 3x
Memory Divider = 333 (1:0.83)
Memory Timings = 3-4-4-8 2T
DDR VCore = 2.60V
CPU VCore = 1.525
PCI Clock Freq = 100 MHz
PCI Clock Sync = 33.33 MHz

My effective CPU Speed = 2.628 GHz
My effective DDR Speed = 478 (238.9 per CPU-Z readout)
Temperatures Idle/Load = 31/55
