Phenom II X4 965 OC Help

I just got my Phenom II X4 965 and I'm stress testing it right now on a 19x multiplier raising it to 3.8Ghz. I have voltage set at 1.4V and it's not stable, so I went in and changed it to 1.425V and now I'm stress testing it.

Am I doing anything wrong here? I _ONLY_ changed the voltage and multiplier from stock 17x to 19x, and the voltage increase. Should I also be changing the bus speed?

EDIT: Crashed at 1.425V @ 19x. Should I go up to 1.45V?

if you have time, you can try different combinations of multiplier increases and bus speed increases. Perhaps you could reach 3.8GHz using a lower multiplier and a lower voltage, stable?

A benefit of using multipliers below 18x is that you can still use cool'n'quiet to allow the chip to throttle down, instead of remaining at the higher voltage/frequency all the time. So if you can reach the same overall frequency in the end, it might be worthwhile aiming for a lower multiplier.

Also, please raise the CPU-NB frequency to somewhere like 2400-2800, that really shows a huge improvement that works well when you overclock. It's not enough just to overclock the main chip.
 
Initial Prime 95 seems Running stable 19x multiplier, 1.45V, will do the things listed above and will report results. Thanks!
 
As I recall, I had to up the voltage to 1.45 to achieve stability at 3800. BTW, your memory and MB play a BIG role.
 
Asus M4A78 Pro, DDR2-800 @ 2.1V (I have no clue about timings yet), 750W power supply, Hyper TX3 which under full load on prime 95 got me to 48C max. I will be getting a 212 as soon as money clears in paypal.
 
I had it running at 3.8 on an Asus M4A77TD which is an AM3 mb with 770 chipset and 8g of DDR3-1600. I'm selling that mb also.

Why? if you have a stable OC and max at 48C it seems to me like a waste of $$$
 
Well, I'm to 3.8 Stable running Prime 95 for 12 hours. I'd like to get it to 4Ghz, but I don't think that's going to happen. Or at least...I don't know how to get it stable at 4Ghz.
 
BE HAPPY WITH 3.8! That is fast. Do you want a stable 3.8 vs 3.4 or a flaky 4.0? BTW what did you have before?

Cool beans. 3.8 is an fair OC on that chip. If you want to try for 4Ghz get that 212 installed, 1.5v on CPU, up the northbridge to around 1.25v, set multi to 20 and test. You want load temps below 55C

Thanks. Will try it. When It's on 4Ghz I get a MASSIVE increase from 3.8 to 4 in benchmarks

Are you doing this for benchmarks?

When I had my 965 BE, 3.8 was the sweet spot. Auto voltage.

Beyond that required a voltage increase which would pump temp and power consumption up quite a notch.
 
I agree with Magic Carpet. Getting a 400 Mhz OC was great for this chip. Running it at 4.0 for Benchmarking only doesn't make sense.
 
Ok yeah, just can't stay stable at 4Ghz no matter what I do. It's sticking at 3.819Ghz right now and that's how ill leave it.

Anyone know why I can't use my mouse every time I change the multiplier? I have to take the mouse out of the USB port and plug it back in twice for it to work.

You doing it live?

Hehe, normal behavior 🙂
 
When I keep boinc running all night, it'll crash in the middle of the night even though it's fine in prime95 for hours on end.

Here's what I currently have, anyone see anything wrong? Or something I may change to make it more stable? It's at 3.8Ghz.
