Overclock athlon x2 245 help

post #1 of 10
Thread Starter 
Hello I'm just curious to ask if I can go any further. I'm currently running at 3.6GHz at 1.424 v, and chipset to 1.35v. And can you also suggest a cheap powerfull aircooler thats better than the crappy stock tingy. many thanks!!!!

If its taking 1.42v to hit 3.6GHz, your probably about to hit the wall.

These chips get to a point where it takes huge voltage for minor gains.

I can do 3.6GHz @ 1.36v, and used to be able to hit 3.75GHz @ 1.46v with no possible increase after that. Tried all the way to 1.55v, at which point I could no longer run 3.75GHz, so watch how hard you push it.

I was running stable @ 3.75GHz on the stock cooler and never broke 48C core temp. So you might be pleasantly surprised how far you can go on the stock piece. As for recommendation, you'll need someone else to chime in.

this is standard voltage in bios. Vcore options are: power saving
standard,
+50mv
+100mv.
So as you can see I dont have the option to adjust in small amounts.

+50mv will raise your vcore volts

If i set vcore to power save mode, the voltage drops to 1.36 v and I can still boot. And another question, wich temperture should i be keeping an eye out in everest? Core1/core2 temp or cpu temp?

This is the case with my X2 255 as well. Hits a wall right around 3.8ghz and 1.46vcore. These chips run super cool, which is why I think they use such a tiny HSF. No need for something bigger.

Keep an eye on core1/core2 temp. I think I read that you are good up to 70C, which means generally you will hit a voltage/clock rate max before you start adding significant enough amounts of heat to get the temp that high. For me, there was no difference in overclocking ability with either a reference BE cooler (has heatpipes and would manage mid 40's under full load) or a massive zalman CNPS10X (where it never broke above 41c at full load). It just could not take advantage of the additional cooling to get a bigger overclock. I have yet to try it with my water cooling rig, but it may be fruitless to even attempt it.

So the short story is that an excellent air cooler might get you a small gain over the stock unit, but unless you chill to sub-ambient temps that "wall" will still be there.

Watch both core temps, but they will stay pretty close to one another. Within a degree or 2.

Me personally, I strive to stay under 50-55C. I think the AMD spec max is 70C though.

Looks like your board is really only friendly to BE processors with unlocked multipliers. Where you would raise multi and then maybe add a tiny bit of voltage to stabilize @ x multi.

Try searching around to see if your board has unlockable BIOS options, usually accessable by hitting CTRL + F11 or similar while in the BIOS.

Everest core temp max out at 47 degrees, and cpu temp at 56 degrees on load. Is this good?

On stock cooling? Yea, your doing good. On that stock cooler, you are at the mercy of ambient temps wherever the PC is located, so just keep an eye on things as time goes by. Maybe get a widget/gadget on the desktop that shows core temp all the time.

Now I'm running back at 3.3ghz, because my north/southbridge was running too hot. Even when i put a small fan on it. If i put a intake casefan i'm going to roll it back at 3.6ghz.

ps. If there are any mis speling in my posts, its because i'm on a mobile.
