Athlon II X2 220 OC help?

post #1 of 41
Thread Starter 
Okay, title says Athlon II X2 220, but really, in general. I have no idea what I'm doing, just that my CPU doesn't want me to touch the multiplier for OCing, so that's out of the picture.

All I know is that:

The highest core overclock I've gotten to work for more than 3 minutes was 3.71 GHz
My memory doesn't like me
CPU-NB going above 2000 MHz tends to make me have to deal with "IRQL TOO MUCH M8"


please, don't reference my rig, as of changing my PSU, it's inaccurate.

Give us more info on what you're doing. What are your temps, what voltages are you at. what's your reference clock, what multiplier.

Currently, temps never rise above 42c, with 1.42 VCore, multiplier is 14x, current bus speed is 242 (stock is 200), current clock equates to 3430 MHz, up from a stock 2800 MHz. I've been successful booting windows at 3.8 with around 1.5 VCore, but bluescreened on login and could not validate. I currently don't have a PSU that should actually be handling this level of stress, but I'm hoping a certain bonus pay I'm getting soon will let me upgrade both the PSU and this CPU to fix that.

I mostly have no idea what to adjust. I'm currently using an MSI 970A-G46, if it bears relevance to anything other than the fact that I need to get some proper VRM sinks.

EDIT: Forgot a few voltages, didn't I?

CPU-NB: 1.147
SB (and NB): 1.0992
DRAM: 1.4995

CPU voltage specified: 1.435
CPU voltage actually received: 1.454

EDIT MORE: Might as well include some meaningless, guesstimated, but real benchmarks, with a Radeon HD 5770, and 4 GB DDR3-1066 dual-channel..
Skyrim (uGrids 7, a ton of other things, including no VSync): 40-100 FPS (compared to 30-60 before overclock)
Loadout (maxed out): 80-200 FPS. A nice doubling, eh?
TF2: Playable. (compared to unplayable before overclock)
Wind Waker: not actually going to post that benchmark, because I'll be accused of piracy I didn't do.

The Athlon II x2 will hold you back. I had an Athlon II x2 250 overclocked to 4Ghz with a Radeon 6770 also overclocked. I game at a resolution of 1366x768. With newer games the x2 will hold you back badly.

I've heard msi doesn't use llc on their motherboards, get hardware monitor and see what your voltages are

...

underclocking, right away.

seriously, I can see why reviews of this power supply (no, I didn't buy this while I knew what I was doing) state that it burned their stuff out

EDIT: no, I don't have a replacement right now. Yes, it's the first thing I'm buying; this is my precious workstation, and I can't have this thing on fiah.

Man, it's been a while since I've posted in this thread.

I've been testing and overclocking it; it seems the overclocking bottleneck is the bus speed. If that exceeds 250 (on my CPU), then no matter what your voltages or multipliers are, you will experience lots of instability in everything. Unfortunately, my multipliers only go up to 14 and 10. If I had any way to unlock these multipliers, I would, and I would bring myself above 3500 core and 2500 CPU-NB/HT.

Does anyone... know how to unlock a multiplier on a multiplier-locked CPU? Just curious.

You can't. You are limited to your reference clock for this chip. If you are stable at 3500MHz, that's pretty good for such a low chip. I assume you already tried dropping your RAM frequency down with loose timings, keeping HT Link at 2000MHz, dropping your NB multi if needed, ect? Do a quick read though of the pdf in my signature (dragin platform) to brush up on things. Maybe there is something you are forgetting.

No, I did not miss anything at all. I've checked everything. I need to keep the HT high because of some of the programs I use, so that's not going down to 2000. And, of course I dropped memory speeds.

Also, no, I'm NOT going to drop the NB multi. HT and NB BOTH have massive effects on things that I use, equal (and sometimes greater) than core. I found out that 250 was the magic number for the bus speed while trying to drive my CPU-NB and HT up more to see how much difference it makes.

AM3 chips really hate high HT Link. NB go for highest stable though. I'm sure you already know this though. What program do you use that requires such high HT Link?
