[HELP] Phenom II X4 B55 Overclock

post #1 of 25
Thread Starter 
Okay, so I just successfully unlocked a Phenom II X4 B55 and started overclocking it. I'm pretty new to AMDs in general and even more, overclocking. I've been lurking a lot and reading as much as I can but I'm still really confused on a lot of terminologies (since they differ so much on various boards and such). I was hoping you guys could help me.

Currently, I have it running at 3.6ghz just by upping the multiplier. But I've read that some people are leaving the multiplier lower, but upping the FSB. I know upping the FSB also ups the RAM and everything else communicating with the CPU (right?), but I'm still kinda confused and would like this CPU tuned to near perfection since it's a present for my dad in another state, and would not have access to it if anything goes wrong in the future.

Current hardware:
CPU: Phenom II X2 (unlocked to B55)
Cooler: Cooler Master 212+
Mobo: MSI 870-G45
VGA: HIS HD5770
PSU: OCZ ModXStream 600W
HDD: 1TB Hitachi 7200 RPM 32MB Cache
RAM: 4GB G.Skill Ripjaws 1333mhz
Case: Rosewill Destroyer
Extra: PCI Wireless G Card

Soon to be Additional hardware:
AverMedia HD DVR
Asus DVDRW
Additional 4GB G.Skill Ripjaws 1333mhz

I ran prime95 for 8 hours and it was stable using the settings in the attached pictures. I would like to know if there is anything else I can tweak to make this better (i.e. some have used 240 FSB and 13 Multiplier for less heat?).

I would also like to OC to 4.0 Ghz if possible (as I've seen from others' with similar set-ups)!

Any help would be appreciated!

DON'T DO IT
MSI 4+1 phase + 125W TDP (unlocked x2 counts) + overclocking = INSTANT DEATH SENTENCE!
Return to stock now and underclock/undervolt! Get a better mobo first!

Listen to that man. The mosfets are ticking time bombs, and because they have no heatsinks either, they might catch fire anytime.

Actually, the real reason I complain is because it is an MSI board. Most (quality) 4+1 boards can actually handle 125W with a moderate overclock (with heatsinks on), but MSI is a definite exception. Their VRMs literally have no quality. I have seen tens and tens of MSI motherboard failures all related to VRM failures, heatsinked or not. Many of them were light and smoke shows. Some of them were on that particular board. On 125W processors. Some at stock speed even. I could post them if you'd like.

Yea listen to xd 1771...trust me i have almost the same set up as you do...same board, chip and cooler, lock the 2 cores and overclock the stock 2 cores, a 4ghz overclock is within reach even without increasing the voltage, keeping everything cool and safe.

When you get the chip to 4ghz increase the cpu-nb frq as well to around 2400-2600mhz, trust me in that config i' sure your dad would not be disappointed.

So, even if I just keep it at stock with 4 cores, it'll still be dangerous? What's the worst that can happen? A fried mobo/cpu? What are the chances? Is it just spontaneous even if I don't use all 4 cores at 100%? Or will it really catch fire?

I leave my computers on 24/7 (I will with this one until I give it to my dad) so I'm really scared about that part of it.

Better safe than sorry...it never happened to me...but the point is, it could happen, trust me, lock the 2 cores and overclock to 4ghz, you can't tell the difference, only if your benchmarking.

What XD said, was on point.

Here's a perfect example of what he's talking about:

i would stay away from avermedia, iv had bad experience with them and so has most people on newegg...........

So this will only happen with MSI boards? With unlocked cores? Or just overclocking/unlocking with MSI boards in general?

And if I OC to 4.0, should I mess with the FSB or the multiplier to get there?
