OC amd 939 4400+

Download and install CPU-Z 1.51. Click the SPD tab for RAM Mfg.

The 2 thngs you have to watch is that your RAM isnt running too fast, and your HT stays below 1000Mhz. As eagles said, drop your RAM divider a couple settings and back your HT multi off to 3x. Then start bumping the FSB. Dont worry about increasing volts, as that didnt help much.

Ive tried lowering the ram speed to 200mhz and the ht to 3x and the multiplyer to 237 so it would be at 2.6, i still get the bsod and it always involves my hd one was atapi.sys and now its ntfs.sys, i updated the drivers from the segate website now im getting the ntfs.sys error, right now i have it at ram 300mhz ht 4x multi 230 and it runs fine, should i get prima 95 or something and check the stability. when it does boot up all the way any higher any time i do something cpu intensive it will lockup and i have to restart the puter and turn down the oc

i got it to 2.616. 237 multi 4x ht 266 mhz ram, 1.4 cpu volts and 2.8 ram how much more could i push it and be safe with heat. at the bios screen its idleing at 40c

So with CPU-Z, what RAM is the system?

click 'SPD' tab.

2.8v on the RAM is a little high. PC3200 400MHz. is usually 2.5-2.6v. 1.45v on the CPU could be 1.5v. Perhaps a shade higher than 1.5v applied on the CPU. With all you have done, if the system won't run stable at higher clocks and upping the vCore won't get it there, there's not much else you can do.

If you are just playing around to see what you can get, have fun. But if you are looking for a performance bump, it is time to dump the Socket 939 and look to the new Phenom 2's. I went from a 4600X2 -939 (overclocked to 3ghz, doing exactly what others have told you here in the thread....memory not too fast, HT speed underclocked, etc.) to a Phenom 2 920 on an inexpensive Gigabyte board, and the difference is night and day. Night and day man.
