Overclocking x2 4400+

post #1 of 26
Thread Starter 
I have a bit of a problem. I can't get past 215 FSB @ 11 multiplier with my cpu. No matter what i do, i can;t get it to post past there. I'm going for at least 2.4 Ghz and i am at a loss here. I have the vCore set @ 1.4, and i've tried higher just to try to get it to post, but it won't even do that. Here are my specs

Athlon x2 4400+ 0532
Asus a8n-sli deluxe
1gb (2x512) GeIL Memory (dual channel)
Sunbeam NUUO PSU
XFX 6600GT 256MB
Stock cooling

My load temps aren;t topping 48 during CPU burn. I can get 32M in superpi in 20s. I like the performance of the processor, but i want to get to 2.4. Is there anything i am missing, or have i just hit a wall?

Need specifications on your power supply and your memory. Post links to both if you can (newegg). Then I will give you some numbers to try.

alright, for 2.4 I dont think you need to touch your voltage, if you want, increase to 1.45 just to give it a better chance. Try these settings.


240 x 10
HTT x 4
Vcore 1.4-1.45
Memory timings 2-3-3-6 (1T)
Memory voltage 2.7
Memory divider 166 (333)

That should be it. Piece 'o cake

EXcellent.....at this point, you are going to have to lower the HTT multi to 3. That's if you keep increasing the FSB. Make sure to keep that memory on a divider and not too high, I dont think it will go much more than 210mhz.
Use this cool overclocking calculator to help figure out which memory divider to use along with multipliers..

you should be able to get that chip up around 2.7ghz on stock air with a bit of tinkering. The X2 4400+ doesnt need much Vcore to OC for some reason. I got mine to 2740mhzwith under 1.5 vcore. After that it didnt seem to matter how much Vcore I added, it wouldnt get stable. Also remember that overall system performance is better the closer you can get to 1000mhz HTT without going over. So it would be better to lower your FSB to 250 and keep the 4X HTT than to go to 255 and 3X wich will drop your HTT to 765mhz.

If your going to go to a 3X HTT I would switch to a 9 multi if your MoBo can handle the hike in FSB.

I have posted this a few times to other peoples question but here goes one more time. Figure out your RAM and MoBo maxes if you want to get the most out of your OC. To do this lower your HTT to 2X and put your multi at 8. Next put your RAM at 266. After doing this start raising your FSB till windows gets unstable. Thiss will let you know how high of an FSB your MoBo can handle.

To find your RAM max put the divider at 400 ( 1:1 ) and leave the other settings the same as the previous paragraph. Set your FSB to 200 and raise it slowly till windows is unstable. When it gets unstable losen your RAM timings. You can also try switching your RAM stix if your a perfectionist. No two stix are the same and you want them to be as close as possible to identical. You want your slower stick closer to the left and you can squeez a bit more performance out of the pair.

Next put you settings at 2X HTT, 266 RAM Divider, 10X multi. Start out at your current max of 255fsb. Raise it till windows is unstable. Now you know exactly what each part of your system can handle.

Now all you need is a calculator, paper and pen. It should only take a few min to figure out the best performing configuration. If you are not sure wich configuration is better to get the same speed just ask.

Thany you guys for your help...but i have one more question, and i thought i would pose it in there rather than start a new thread. I'm hitting roughly 51C on load...i know that is a little steamy...i am going to get a aftermarket HSF...everyone raves on this board about the Big Typhoon. I'm really looking at the zalman 9500 or the thermalriht xp-120. does anyone have suggesstions, was going to watercool, but i don;t want the hassle, and it would require extensive case modification. Thank you much.

The Thermalright XP120 or the XP90c will perform better than the Zalman 9500 with a reasonable fan on them. Probably the XP 120 and a Thermaltake Thunderblade if you don't want the Big Typhoon.

Actualy 51c under load isnt bad. That chip is rated for 71c if you go look it up on the AMD website. Its still better to keep it under 55c even though AMD says its safe at 71. If Both cores are under full load and your temp is 51c you are fine and need not spend time and money on anything new. Also if you used AS5 you can look forward to about a 5c drop in temps over the next month or so.
