ASUS A7N8X-E Dlx & XP-M 2500+

post #1 of 13
Thread Starter 
Ok, so I decided to grab an XP-M 2500+ for my box. I got the CPU in last night, and I am unable to clock it above a 12.5x multiplier. I can run 2500Mhz stable, but if I try to go to 2600 or 2700mhz, it will go to 1000mhz at bootup (no errors) (and confirmed in windows (just glanced at properties of my comp to verify)) even though the bios says 200mhz x 13x multiplier (windows also reflects 200mhz bus speed). I have the latest bios release, and will probably be putting the tweaked bios on it tonight with updated sata, etc..

So I'm thinking either the board only supports up to a 2500mhz chip (listed as "Unknown CPU Type" at bootup btw), or the board has the chip at the proper speed, it just won't list it as such. It's probably the former but I figured I would ask.

At 2400mhz I'm running at 1.6v (0.25v higher than the stock 1.575v) at 46 C (full load), using a Vantec Aeroflow II. Case temp is 28 C. 2500mhz I have to kick the voltage to 1.7 and it runs more like 48-50 at full load. It's sitting at 2400 till I get my watercooling kit thrown on this evening.


I also have another board I could use, an ASUS A7V600-X.. Anyone know if that clocks any higher?



Any help would be appreciated!!!

Ok, so I figured out that I had to do the 5bit wire mod to get to multipliers above 13x. http://www.ocforums.com/showthread.php?t=279392

TI did the mod, but when I have the wire mod in place my system will only boot when set to a 100mhz or 133mhz fsb. I'd really like to try for 2700mhz, but I want to keep the fsb at 200.. I think the best I'm going to be able to do at this point is to put it at 200x12.5 and then push the fsb up a bit, I know I can get it to 2600mhz if I push the fsb up to 209-212.

Maybe you can up the fsb a little, but I dunno if that chip goes a lot higher than 2500 as it is a 130 nm chip. Maybe if you overvolt it a little more, thow 1.7V is already a lot for a mobile cpu.
The other board, I don't think so. It's based on Via KT600 as far as I can tell and these are not so good (read terrible) OCers.

Good job, btw. I tried for 4 months to get my barton 2500+ to go to 2500MHz, but only managed 2475 or something like that.

To give you more correct information about your cpu..
For the Mobile XP (45w) cpu's their stock voltage is 1.45v, whereas the stock voltage of the non-mobile XP cpu is 1.575. As with anything that invloves computer not any 2 parts are equal.. meaning that you are not going to get the same exact clocks as everyone else. And as far as the multi, you may have hit your limit with that. An increase in your fsb will actually give you better speed, example; 220x11 will run faster than 200*12. This is becuase the data is able to transfer faster from the cpu to the mem and so on. IF you don not have the current BIOS for your motherboard, you might want to try and flash that as well, it may help.

Good info Jonnie
BTW... I've run my 2600m as high as 1.775 to get over 2600+... it's geared down a bit for regular use running 1.70
A Mobile will post as Unknown, thats normal.

BTW... use the USER CP link @ top of page and fill in your system specs!

Actually I grabbed the Asus "UBER BIOS" before I started all this mess, I was already at the latest revision though. Bios hasn't made a difference, but it's nice to have updated SATA firmware

I didn't think there was a real problem with supplying more voltage, as long as the chip stays reasonably cool. That's the whole point of getting a mobile chip, they have more room to play as far as voltage goes (because they are underpowered to begin with) and no locked multipler. I was under the impression that it could handle just as much voltage as a regular non mobile chip, but if I'm wrong here please chime in before I go beyond 1.7v

I think pushing the fsb a bit beyond 200 will be the way to go, I have pc-3200 and I'm pretty sure since it's just regular memory that I'm not going to push it to 220mhz. I've got a stick of ballistix here, but only 512mb of it x 1 stick, and I like running in dual channel. I'll play around tonight and post my results here.

The watercooling setup is going pretty well, not as low temperature as I would expect (but it hasn't been 24hrs yet either! - still some air bubbles lurking?), but I got a fairly low end water system anyway. I've got another waterblock coming this week, and I have some other odds and ends to put on (vga block, more fans, fan controller, etc) as well.. I'm thinking about getting an external radiator to add on, but I want to see what kind of temps I get with this round of parts first


Thanks for all the help!

Well after a bit of playing around, I got it to 208 x 12.5 (2600mhz). I had to push the core voltage up to 1.825 to do it though. I could boot at 2625mhz at the same voltage, but prime95 failed at that speed. I have regular PC3200 anyway, midrange stuff. It's running at 46C idle and peaks at 53C at full load using prime95. I have a better water block and arctic silver 5 coming saturday, so the temps should drop, they are within range at any rate.




I have another 2500+ XP-M coming (advance rma), this one had a few chips on the die when I got it. It's an OEM pull.. Chips aren't really that bad at all, but a chip is a chip, besides whichever OC's better is the one that won't get shipped back.

see chips:

I'll update this post with some more pics on sunday after I get the new block on and everything else thrown in.

I have same board, its not running at mo, but in bios below 200mhz is the percentage. is it 100%?? Later when im on mine i will look properly. I do remember having to set 100% for FSB then i was able to install 3.2 athlon chip> Sorry a bit vague!

Most Mobile Skt A CPUs seem to be unfriendly to high voltage settings... I got no where above 1.8v ... as many others had reported.
