CPU OC in BC2 leading to worse performance?

I have the i5-430m and I've been toying around with processor OC.
I'm using setfsb.

In BC2 I've tried 3ghz with turbo on, 2.7ghz with turbo off (with throttlestop) and they both yield worse performance than stock. This is in BC2 on the same level, without me moving the mouse, and benchmarked with fraps.

It's about 10 FPS average higher with no OC.

Weird thing is, I tried NFS hot pursuit and I get better performance, also verified by the same settings, same race, same car etc.

EDIT: It's not throttling.

 

not a big enough psu or maybe your laptop has some throttling bs going on? What happens to your gpu load and clocks when in game and overclocked?

 

Both 99% and same clocks. I can even run WDprime32 on it and it's not throttling, confirmed by CPU-Z frequency and throttlestop monitor.

 

As with any modifications, you will have less reliability. This applies to modifying a car or any motor or electronics. As far as my research goes, BFBC2 was specifically designed to take advantage of the recent CPU architecture, and so tampering with your CPU specs just might be causing major conflicts, hence the bad performance you're reporting.

 

So how come it leads to better performance in Hot Pursuit?

 

overclocking messing ram up and causing issues? ram can't handle overclock in that game? Honestly i am lost :/

 

Again I never researched Hot Pursuit, but the many articles I've read about BFBC2 and it's development is that they put alot of emphasis on utilizing the modern dual and quad core CPUs. You have to take that into account and how it correlates to tampering with CPUs. It will have an effect on the program, either negative or positive. And in the OP's case it has negative results.

 

but overclocking shouldn't have a negative affect unless it over a stable clock or overheats. His appears to have neither since stress tests and other benchmarks and games do better. I am rolling with maybe ram or psu. Only things i can come up with but they are pure mostly partially un/educated guesses lol

 

jacob808, your replies defy all current knowledge of overclocking processors. Thousands of people overclock similar processors and use that game without letting off a hint that they are experiencing a similar issue.

Bearclaw, there is obviously a problem here, and things like this are not entirely unknown. They can just really difficult to get to the bottom of, but there is always a very logical reason. What happens if you overclock, but only a little bit?

 

At about 2.65 gHZ it still seems okay.

One interesting thing though:
in wPrime at stock freq my multiplier is x19 all the way through the 32 million test. At my current 2.65 GHz it sometimes goes down to x18 multiplier. I think the x18 is turbo for two cores? while x19 is turbo for one?

Can this be related?

edit; just checked 2.88 GHz and it's slower again.

 

what is thee temp of your cpu? Can it be maybe TDP is being hit and its down stepping? Maybe the temp is fine but is it using more power or giving off more heat than it allows? Someone made the comment in the SB thread that Even if SB is liquid cooled and stays cold it can't be overclocked past a point do to the TDP limit. Does that only count for the SB or does this affect yours too?

 

Temps are around 65 on wPrime

 

you might be sucking too much power draw at those clocks, and your computer can't supply the correct voltages to each component.

remember, overclocking affects more than just your CPU, and depending on how an application utilizes it, it may have adverse affects.

have you tried overclocking mixed with undervolting your CPU? it really does sound like you're pulling too much power from something, or that your clocks are throttling down.

 

more and more i hear i think its the psu but i am by far no expect. You need to ask liek allurgrocies or thalanix or maybe forge. they might know. Or ask uncle webb

EDIT:good place to post is in a setFSB thread. I think they made a thread dedicated to that

 

The odd thing is that the people I ask in the MSI forum who have the same chipset in SetFSB are able to overclock their 430m to 2.8ghz.

 

weird....no clue

 

There is a lot more to the computer than just the processor and chipset that affects the overclock. And even if you did have identical hardware, you can't expect all of it to overclock the same. Finding what the least common denominator sounds like it could be pretty tricky or time consuming in your situation. If you want to, go for it, or on the other hand if you don't have the stomach for it just be happy you can stably overclock to 2.65Ghz.

 

ur so unhelpful and pessimistic trottel...think come up with ideas...damn ^^

 

Well on a laptop things like this are much, much more difficult than a desktop where things are modular and include many many options for overclocking (usually). Bearclaw is going to have to get his hands real dirty if he wants to get to the bottom of it. First of all cooling must be improved as much as possible to see if that affects anything, and not just on the processor. If underclocking the gpu, replacing all the thermal paste, and blowing a box fan at the bottom of the laptop doesn't help anything, that can pretty much be ruled out. Another issue is power supply. If on battery it doesn't do any better, then we know it is an internal problem. It could be cpu voltage is too low, or the power regulation circuitry can't handle it. This is where the going gets tough. It can be beat, but probably isn't worth it to try.

 

going on battery wouldn't really rule anything out. As soon as you go on battery that would make everything downclock to a set limit. My laptop gpu and cpu downclocks on battery. Even with those downclocks it can still overload the battery fairly easily where the PCM/PCB kick in.....done it already lol

This wouldn't rule out the psu at all. What he should try is calculating the total power consuming of everything and than see what his psu output is and efficiency is and count the inefficiency in and see what the psu total output is and see if he is overloading it

 

I've fixed the issue somewhat.

I didn't know the TDP had to be changed by right clicking in throttlestop. Once I did that I changed TDP to 40/40 and now everything runs at x19 multiplier.

Stupid thing now is that games like Mafia 2 runs at a faster pace... lol le sigh.

 

well thats good!

 

After restarting after OC'ing the running too fast issue seems to be resolved...

 

Yay! Hooray!

 

lol I give up. The performance is still worse from before... I think the processor isn't the problem anymore but something with the ram probably.
