Athlon II X2 220 OC help? - Page 3

post #21 of 41
Thread Starter 
Well, I did all of this. It was rather successful, but I couldn't get the FSB past 260 without a BSoD happening on startup. I tried increasing the relevant voltages, which sort of helped with delaying them, but wasn't really stopping them. I stopped this at 1.344 on the CPU-NB, and 1.43 on the core (up from a stock 1.34!), since I feared that I might catch the insulation wall behind my computer on fire*. Funnily enough, the only issue I've gotten yet at 260, though, was after raising the CPU-NB mult from 8 to 10, and was a CLOCK_WATCHDOG_TIMEOUT, which I understand is largely a software issue that can be aided in happening by an OC being a tad off. I raised my voltages and haven't yet experienced it again yet. HT remains at 2080, core is at 3640 right now, and the CPU-NB is at 2600.

*= no, I actually did it because my case airflow has one intake and one outtake, intake operated by the CPU cooler through the expansion bays, and outtake operating behind the CPU. NB heatsink not in the way, and the extra speed of intake would cause my GPU to heat up more, which is saying something, because it's already suddenly taken to loading at 78 instead of the 69 it loaded at a month ago.

And, I didn't edit my post because it had gotten old enough that edits would be practically invisible.

Try lowering the cpu nb by a little bit and trying for a higher CPU frequency first. What cpu cooler are you using?

It's a Zalman Performa, more than capable of cooling this thing.

But, I just ran the Dolphin benchmark, which is a rather taxing benchmark based on the Dolphin emulator, and no issue with that BSoD, so I guess I'm fine now that I raised the CPU-NB voltage.

While increasing FSB you may need a slight cpu nb voltage bump. Try getting at last 3.9Ghz.

Here's an old pic of p95 crossing 9+ hours at 4Ghz. I used 1.55v for the run cause I was experimenting with fsb vs multi overclocks. Turns out fsb overclocks did need a little more vcore. With a higher multi I could get 4Ghz with 1.52v. But it was fun experimenting smile.gif

Oh, you realize though, that I'm using a Deneb-based Athlon II, and that's a Regor? They should perform completely different with overclocks, though, I guess the Deneb should actually go higher...

I'll try some more in a few minutes.

Just tried it.

Continues to reject 265 on the FSB, no matter what the voltages are. Allow me to show you all of the start-up BSoDs I had:

NTFS_FILE_SYSTEM
PAGE_FAULT_IN_NONPAGED_AREA
That really garbled one
And four unnamed BSoDs.

I DID get one good boot and I ran Prime95. No matter what, it always failed the first test, because one core was rounding the number to 0.5, and the other was rounding it to 0.493..., when it was supposed to be less than 0.4. So, no more pushing for 4000 for me.

We had the same chip except that mine was clocked higher at stock. Your chip isn't a deneb chip. Deneb chips are Phenoms. Yours is the same as mine. What vcore did you try at 4Ghz?

Actually, my chip is a locked Deneb. If I had been lucky, I would have been able to unlock two extra cores and an L3 cache, but I wasn't lucky.

I never tried jumping to 4GHz. 265 would have given me 3.71GHz. But, by the time I gave up, I had 1.39 on the NB, 1.41 on the CPU-NB, 1.51 on the core, and had increased my DRAM voltage slightly, since I was testing a theory of mine about the DRAM multiplier, after noticing that I'd get BSoDs even at stock if that multiplier was DDR3-800. Raising that back up to DDR3-1066 (brought the actual frequency up to 1415) caused, instead of a buttload of memory-related BSoDs, a nameless BSoD. But, I gave up and went back down anyways.

Okay. Yeah after checking, a few Athlon II x2 220's did unlock. Have you tried unlocking one core? If your L3 cache doesn't unlock means your chip isn't a deneb chip. The deneb chips unlocked, stable or not but they unlocked. It isn't true that Phenom II chips overclock better than Athlon ones. In fact my friend, an OCN user here, has an Athlon II x3 445 and it unlocked into a quad core with L3 cache. But it overclocked further as an X3 than as an X4. The difference between Phenom II's and Athlon II's is mainly L3 cache.
FSB limit is more of a motherboard limitation than a cpu one. If you could get 3.8Ghz it would be pretty good.
