Axp mobile questions

[Sylvanas]

well ive hit a brick wall with my locked barton 2800 overclocking wise. and since im quite enjoying this tweaking, im in the market for an Axp mobile. i have an Aopen ak79d-400vn mobo (nforce2 ultra 400 chipset) will this support a barton 2600 mobile? ive heard that the nforce2 ultra 400 supports all bartons, though i dont know if this includes the mobile range... also is there anything i should know before i order one? any steppings to look out for? ill be putting my volcano12 and AS5 on it when i get it so i think im ok cooling wise.

That board should handle the AXP mobile chips just fine. You might need the latest BIOS update, but that's about it.

As far as the mobile chips go, pretty much all the steppings are good. I've got a 2600+M that's running at 190x12.5 = 2375Mhz with 1.65v. The chip could probably go much further, but my older 8RDA board doesn't like FSB speeds above 190-195.

NF2 Ultra 400 boards generally support mobile bartons, assuming you have the latest bios. A good 45w 2600+ or 35w 2400+ would suit you well, probably allowing a reach of 2.6ghz with your level of cooling, assuming you don't FSB overclock far past 200. People around here are saying the new IQYHA 35w 2400+ mobiles aren't doing quite as well...I dunno, never tried them. Mine were all AQYHA and did 2.6ghz @ 216x12 with 1.9v, not too shabby on a Volcano 7+. I guess it's something to keep in mind. The 35w 2400+ is around $10 cheaper if I remember correctly.

ok, so i buy a 2600, does it really matter if its 45w or 35? also i have bios revision R1.12 of my board, there are 2 revisions above it that only fix minor things (eg 1.13 fixes Axp3000 boot problem and 1.14 adds support for sempron processor) will the mobile bartons run on my revision?

 

[Sylvanas]

anyone?

I used that board briefly, and the highest multiplier setting that would post was about 12.0. Anything higher and the board would reset back to 6.0 and 600 megahurtz. If you can get 12 x 200 (2400) that's a pretty good overclock anyway. Get the highest rated mobile barton you can afford. The lower the rating, the less likely you'll get a good overclock. Don't worry about whether it's a 35 watt or 45 watt chip, focus on getting a good heatsink; one of the thermalrights with a 80-92mm fan should work fine. Panflo is quiet, but I use a "zalman fan mate 1" to reduct rpms and noise. I hate noise, and don't use any case fans and a single fan power supply by enlight.

alright thanks guys ill order a 2600M tomorrow

VDD volt mod for 8RDA series motherboards

Couple the volt mod with better cooling for the chipset and you are on your way to 200+ MHz FSB.

2600 is only available in 45W

it matters cuz for overclocking you want the highest speed at the lowest voltage for the most headroom in overclocking

I just got a 2400+ 35 watt and it's running 2.4@1.7 right now. It's a IQYHA. Will be trying for 2.5 tomarrow, I don't really want to push more then 1.75 volts though, my cooling is kinda so-so.

so are there any benchmarks around that show the overclocking headroom the 35w offers over the 45w. i want to achieve the highest possible frequency on my mobo (maybe 200x12 for starters) so would the 2600 do that? or would a 35w 2500 be better?

no there are no benchmarks that i know of and there is no 35w 2500+

but from person experience ( i've had both ) and from what i've seen from other users' results, the 2400+ and the 2600+ are pretty consistent with respect to eachother if you get a good stepping, such as the iqyha ones
