how to overclock 3000+ Venice?

[leegroves86]

I have a E3 3000+ venice core proc, cooled by asus ICE STAR (runs 30 C). Useing an Asus A8N-E mobo. 512 (2x256) Kingston pc3200 CAS 2. Thermal take 480W PSU

I used to be overclock my 2500+ barton easily, all u had to do was adjust the multiplier and that was about it. These days with HTT, ram dividers (wtf?), different voltages, adjusting FSB and what not... I'm lost. The best I can do is 2.0GHZ stable, which Is completely crap. I want 2.2 or 2.4 if possible.

I've already read the main O/C thread and I'm still lost. Can someone just tell me what to do to reach 2.2 or 2.4??? Recommend settings?

bump?

It's not really that complicated, but if following the walkthru in the CPU forum is too confusing, I'm not really sure where to start.

How did you get it to 2.0 GHz? You need to keep the HTT <1000, so one you rasise the HT (FSB), you have to lower the multiplier to 4X at least. Leaving it at 5X will cause instability. Also you might need to run a RAM divider.
Do you understand all that?

Not really. All I did was set multiplier to 9 and speed to 223 which gave me 2.0ghz. What is HTT at stock? Is it labeled HTT in bios? If i lower my multiplier to 4... wouldn't that make it a LOT slower? What the hell is a ram divider? I've never heard of them.

please post system specs

what kind of ram do you have? if you have some cheap PC3200 you'll need to use a ram divider, try setting that lower so your memory wont be overclocking when you raise FSB.

Also you want to keep FSBxHTT speed at around 1000mhz, dont go over this a lot

for this setup ive got i'm using
256 HT(FSB), 4X htt, and memory divider using 166 (lower dividers give me issues which is extremely limiting my overclock)

HT multiplier is most likely set to the max of 5 as default. You definitley want number times your HT to be <1000. So 4x will be good up to an HT of 250. Really anything over 800 is perfectly fine. Even lowering it to 700 would not produce any noticeable loss in performance.

When you increase the HT, you are also increasing the speed at which your RAM runs which can cause instability. You have PC 3200 which means it's meant to run at 200HTT. By setting the RAM speed to 166 (which is a 5/6 divider) when raising the HT >200, you will keep the RAM at a speed which will allow it to run stable.

So for instance:
Set HT to 250x9=2.25GHz
Set HT Multiplier @4x = 1000HTT
Set RAM divider to 166 = 208 (take your HT*5/6...250*5/6=208)

Can you follow all this now?

try clockgen

Good thinking, ClockGen is a great/faster way to test how far your chip will go, but don't forget to devide your ram, lower HTT and set your voltages to whatever your comfortable with all in Bios (my cpu runs this OC w/ default voltages just fine)
