How to overclock amd phenom x4 b55 - Page 2

post #11 of 18
Simple rule. With overclocking if you are able to do things you did before OC'ing then your system is stable. No need to run Prime95 for 12 hours. least you can run AIDA64 for an hour or AMD overdrive stablity test. That is good enough

Tnx man..so relieve with that smile.gif so when you overclock and then BSOD that's the time you should adjust the voltage but without increasing over 1.5 right?and a good a ram 2 i forgot..tnx a lot

here are the results i took with OCCT

so this means that i really got a stable OC?

And 1 more thing why is that when am on windows7 x86
the FPS drops to half?is it my RAM or GPU?
i only got a evga gt 220 and when tried to OC core to 750 with evga precision the game crashes or hang.do i need to change my gpu?if so what
GPU is best for my A880G+ board.tnx wave2.gif

The 220 is a lacking card in many ways. AMD/ATI and Nvidia both have nice cards out right now so there are a lot of choices. What do you want it to play and how much can you afford?

I've thought twice about this and realized you are running on a Biostar A880G+. I'm assuming you have a tower heatsink which does not cool the mosfets.

An unlocked Phenom II x4 B55 consumes 125W. the 880G+ only has a 3+1 power phase, 3+1's usually being rated only for 95W; above all, however, they are not getting any cooling. Because you have unlocked, overclocked and have not provided proper mosfet cooling or a proper power phase for powering the CPU in the first place, there is a very large fire risk associated.

Your board may see the end of its life during a long Prime95 test run when more than 125W is being pushed through uncooled, unsuitable mosfets. You should down the clocks to stock, the mosfets could probably at least handle 4 cores at stock but overclocked the risk is just too high. I don't want you to suffer from a terrible RMA process and a wrecked mobo/processor.

TL;DR, due to weak mosfets and no mosfet cooling I do not recommend overclocking or unlocking on this board.

xd 1771, you are totally overreacting. Read this...

CPU Support List

The board not only supports X4 chips up to 125W, it also supports X6 chips up to 125W. If OP is worried about heat he can invest in a few aftermarket coolers for the VRMs. Not every board is going to go up in flames.

Just remember that adding voltage adds heat.

That doesn't necessarily mean support when overclocking or extended support, or a guarantee of support for all the boards. Additionally to the weak mosfets Biostar is a weaker motherboard brand; if it was someone such as Gigabyte I probably wouldn't mind as much. Aftermarket VRM coolers don't always solve problems; even heatsinked VRM's (4+1's specifically) have blown out due to 125W or 125W+ processors. Also, actual rating of this board aside, generally most motherboard brands rate boards with 3+1 mosfets at 95W max only.

Where are you getting your information from? How are you so certain that this is a 3+1 board? Biostar is a good motherboard brand anyway. I am running an overclocked and unlocked X4 B45 on my board with zero issues. It has run this way for a year. And I don't have a fire extinguisher sitting next to the computer. Honestly, if you are going to make claims of boards catching on fire you should have some proof to back it up. I know better than to keep pushing my OC on this board but my VRMs are not even warm.

I say to OP do whatever you want. Keep an eye on the VRMs and see if they are indeed getting hot at all. If not then push it. What fun is OC'ing if we don't risk blowing something up now and again. As I said you are overreacting for sure. For every person that says that Biostar sucks and they are weak there is a person who is successfully running a Biostar board (and maybe even running an OC on it). Hell my kid's computer is a cheap Biostar G31 board and he is running an E5200 OC'd up to 3.0 with zero issues.

Look, everyone has to decide how far they want to push things on their own. They put out the money for their stuff. But ringing alarm bells every time someone OC's on a 4+1 board is ridiculous.

With that board I would stop OC'ing at the point where extra voltage is needed.
