Just got a mobile barton 2400+ from newegg. Slapped it in and right away got 11x200 at 1.575V which is what I wanted. Installed windows and everything was fine. Decided to run prime95 to test it out, and I got an error message after 6 minutes, so I decided to up the voltage to 1.65. At this voltage I got an error after 16 minutes, so I decided to slow it down at 10x200. It won't boot at this speed or any speed faster than 1700mhz (200 x 8.5). What's going on? It's in a cooler master case with a SLK947U heatsink idling at about 41 degrees. It won't boot, no matter what voltage I give it, up to 1.70V. What should I do? RMA to newegg or will it come back...?

I've never gotten prime 95 stable with any of my boards. I use sisoft sandra. Run the "burn" section. It cycles for 10 times. 2.2 is a good speed for the mobile barton. Anything higher and I would use water cooling. Newegg has a refurbished kit for $76. Ewiz.com has a globalwin water cooling kit for $65 that's very easy to install.

yeah only thing you can do is more volts but the volts you putting into it are already high for a mobile at that speed. might be a ram issue have your tried bumping the volts on it up a bit? try 2.8 or 2.9

I'm going to have to disagree here the heatsink that dheffer is using is far superior to any of those water kits listed he'd have to spend over 120 to beat his HSF. also as long as he keeps his temps under 50C thier is no reason you can't do a mobile at 2.5 on air. mine did 2.6 on air but was a little hot so I went to water

try going under 200 with the FSB...
i'm doing running my xp-m 2500+@2430 something with 195x12.5 as it will not become stable with 200+ FSB;
AMD screwed their newer mobiles FSB-wise; that's my guess anyways...

uhh.. yeah tell that to my mobile 2500+ which could do 250 mhz (sold no longer belongs to me).

woah i blinked and had like 5 responses. only gripe i have is that prime95 wont run for more than a few minutes, but I've ran 3dmark 01 and 03 and been playing games with no signs of adverse overclocking. ah well might try a 333mhz bus but i love the memory bandwidth. 2.2ghz is fine by me as long as its stable

ps - is that water cooling kit junk? thats really cheap, but then again my slk947U and 92mm panaflow was 26 new =) gotta love running cool with a 1800rpm fan

also, whats the safest to reliably overvolt your ram to? 2.8v or what? i know its tougher on it, but whats the "comfortable overclock"?

on your ram don't worry about it I run at 2.9v all day long and wish I could give it more the ram is hardly warm to the touch. I've seen people give up to 3.3V with volt mods

Lower your cpu speed down to stock temporarily, test your fsb/ram timings with MemTest. If that is stable test it with Prime95. If all is well, then raise the cpu speed to determine the max. If you are trying to overclock the fsb and cpu speed at the same time it is difficult to find a stable speed.

Also I have seen many sticks of PC3200/3500 that are not 100% stable at 200MHz. I am running with 2 sticks of PC2100 at 203MHz now, both of which run tighter timings than the last PC3200 I had.
