2500+ Overclocking

[Fides]

I'm new to this, but here goes

Having read about the overclockability of the 2500+ in other posts I tried doing the same to my own. On my a7v8X Mobo w/ a volcano v7 fan I first set the voltage to 1.75v at 200FSBx11. Windows started to load but i hit a blue screen. I then loverwed the votage to 1.7v and the same thing. Lowering it anymore stopped widows from loading at all. I'm not familiar with voltage settings but im pretty sure my cpu heat can handle a .1v jump. Anyone have any ideas on how to get this thing running like a 3200+? Also I'm running at 46*C/114*F, what would be the maximum suggested heat to run my pc at.

Thanks for any help.

Hello Fides,

It could be your Mobo, I to have a similiar if not the same one. I can't go past 182FSB due to the lack of a PCI/AGP Lock. Bit annoyed to be honest.

Mark.

Did you try any voltage higher than 1.75V? Your 46C temp is fine, once you hit the 60s then you should start becoming concerned with heat limiting your overclock. Keep in mind that not 2500+ will hit 3200+.

I don't believe your board has a AGP/PCI lock, but at 200MHz FSB you should be able to use a proper divider to run your AGP/PCI in spec.

Can you change your multiplier? If so, try that and incrementally go up to find a stable speed. Try bumping your voltage up a bit more though, just to test.

 

[MLJGTI]

how do you incorporate a divider?

 

[dnuggett]

First, you did it backwards. Start by increasing the FSB in steps until you can't run Prime 95 stable. Once you get to that point, up the vcore but go no higher than 1.75. At least it's really not necessary and the extra stres put on your proc is not worth it IMO. Also go no higher than 60 C on your temps. Your board does not have the lock, you need to look at Nforce2 boards for this. You also have not mentioned a key component in all of this, what RAM brand/speed are you using?

 

[Fides]

The thing is in my bios I have an option to goto 2200Mhz. I'm at 1833 right now(the standard). I've heard it said that my multiplier is locked and the only thing i can change is the FSB. My real problem lies in the fact that If i put the voltage over 1.7 volts, It runs but windows crashed. Any lower than 1.7v and my computer doesn't start at all because It doesnt ahve enough power i presume. I do believe if i up the processor speed it will be equivalent to a 3200+.. because a 3200+ has 2.2ghz

Also whats a good cooler for a decent price (30-40$) and themal gel.

ThermalTake Silent Boost or Thermalright SLK800/900 + plus whatever fan.

If you sucuessfully overclock, then yes your CPU will perform the same as a real 3200+. But don't get into the mentallity that all 2500+s hit 3200+ no problem/

Assuming you have PC3200 ram, it sounds to me like this is yet another case of a wimpy power supply. Overclocking is really harder on your power supply than on any other component in your case, which is why we all use quality (i.e. expensive!) psu's. It's something to think about, anyway.

Like someone said earlier, YOU'RE DOING IT BACKWARDS! If windows crashes at your current settings, you have to INCREASE the voltage not decrease to get it stable. Crash at 1.7v and won't load at all less than 1.7v should tell you that. Try increasing it to 1.71, 1.72, 1.73 until windows loads and you can run Prime95 without errors.

Of course some people don't like going that high with voltage, do so at your own risk.

EDIT: I misread a little. You say you have already gone over 1.7v? Then you need to go higher to get it stable.

Let me make it a little more clear..... You start stock volatge settings and up the FSB in increments using Prime 95 as a stability guide. Once you get the system unstable increase the vcore 1 increment (whatever that is for your mobo) and restest. Increase the vcore to a max of 1.75. You may also need to increase the RAM settings, and that can be adjusted after the vcore @ 1.75 fails to get you higher.

AND YOU NEVER DID SAY WHAT RAM YOU ARE USING???

 

[WobbleWobble]

I think 1.75V is a bit conservative. It would be ok to bring it up to 1.85V (actual) just to test, but I would not run a Barton for extended periods at that high of a voltage and as dnuggett suggested, 1.75V would be a safe voltage to run your Barton for extended periods.

 

[robcy]

are you using DDR3200 Ram or are you overclocking DDR2700 also. Did you raise the mem voltage?

Hi, I'm running Athlon at 2.4GHz@2.1V. Idle is 55C and Full Load is 62C. Will it drastically reduce my CPU lifespan? I'm getting a Athlon64 when WinXP64 is out anyway.

not a clue. buy an uneducated guess would be ... don't worry about it. if it prematurely dies .. just get a 50USD replacement until XP 64 releases.

Your voltage is much too high. Your temps are temps are a little too high. Becasue of the voltage I would say yes you are decreasing the normal life of that CPU quite a bit.

My temp at XP 2600+ is around 54C with stock fan(3000rpm). I can run 2.3GHz at 1.85V, 47C idle, 5000rpm and it's stable. 2.4GHz requires a jump to 2.1V to be stable again. Anyway, I'll reset to 2.3GHz after this (worrying).

Resetting would most likely help the life of that proc. I would be a slight bit concerned at 1.85v too. I personally won't go above 1.75 for an extended period of time. I'm not too sure how much of an effect a 5% voltage increase has on processor life but I do know it can't be a linear 5% decrease in life it must be something higher, unless it is linear to a certain voltage (x) and the ratio climbs higher above that point (x). I'm curious to see what others think and if they can point to any studies to reflect an equation.

 

[tinyabs]

I'm wondering about this.

Which factor will kills the processor? Heat or Ampere or both?

right now, its at idle with a cooler master 4 turned the knob to mid.



Picture here

lower right hand side near the AIM is the temp of the CPU 36

I'm sorry, why do we need to know this?

cuz i want to,problem?

No, if you want to post meaningless things go right ahead!!! I was just asking to see if you meant to post that in another thread, guess you meant it to be in outer space in this one.

Arite.. here's an update.

I just increased the multiplier from 11 to 12 and im not running at 2.0(from my 1.83) ghz, 45*C idle and about 48 on full load. The thing is, when I change the multiplier things go fine, but when i atpempt to change the fsb things go all wrong... my computer doesnt even start no matter what voltages i put. Any suggestions?

Also.. how does increasing voltage help performance? like 1.7V vs 1.8V on my vcore.. what difference will that make if at all on my performance.

Thanks for your help.

Fides for the 3rd time in this post, what type of RAM are you using? I have a very strong feeling that this is holding you back, but you haven't answered the question yet.
