*Update* XP-M 2600 results

[BlueWeasel]

4.1.2001 Update

I got the 2600+ installed last night in my 8RDA board (see below). I immediately fired it up to 182 x 12.5=2275mhz at 1.65v and it ran like a champ. I was thrilled at the results, but wanted to see how far I could go...

Based on my experience with my locked 2500+ chip, I just assumed that it was the 8RDA that was holding me back from the magical 200 FSB. Alot of the early revision Nforce2 boards couldn't hit 200 FSB without modification to the Northbridge voltage. Anything over 184 FSB with the 2500+ would just cause the machine to reset, regardless of the Vcore voltage.

Last night, I start bumping the FSB on the new XP-M 2600 to see how far it could go. Honestly, I was expecting to see the same problems that I had with the 2500. After a few tweaks and stability tests, I am now sitting on 200 x 12 = 2400mzh at 1.7v. That's a nice little OC compared to the 2500+, which could only do 182 x 11 = 2000mhz.

Well, I finally got around today to ordering a 2600-M from Newegg. I hope I'll be able to push it further than my current 2500+ (locked) chip using the same MB and RAM.

Here's what I'm currently running:

Epox 8RDA NF2 board
1gb RAM (combination of PC2700 and PC3200)
2500+ (locked) running at 11x182 FSB = 2.01ghz at stock voltage

The Epox board is what is holding me back from 200 FSB. It's an early revision, and doesn't like anything over 182 FSB.

Regardless, I want to keep the Epox board and RAM for a little while longer, so it looks as though I am stuck at 182 FSB for right now. My question is what is the maximum multiplier I could probably use with the new 2600 mobile chip and keep my voltages at 1.80v or less?

182 FSB x ??? = ????

I am hoping for 182 FSB x 12.5 = 2275 Mhz.

Weasel, how do you know that it's your board holding you back, when you have PC2700 ram in there?? Anyway, yes, 12.5x is the maximum multi, unless you own an NF7-S or an A7N8X-Del.

Dude! I am disappointed! I figured you'd remember my troubles.

This should jog your memory

Basically, my Epox board needs the northbridge voltaged modded in order to hit 200 FSB. Alot of the early revisions had this problem, as the early NF2 boards were not meant to run at 200 FSB (although some do with no problems).

I've tried running with a single stick of PC3200 at 2.8v and my board will reset at anything above 184-185 FSB.

You can alter the multi by using the pinmod. It's pretty simple. I have an Epox board (a KT333) and chose the socket mod (where you put the pieces of copper wire in the mobo sockets and not around the cpu pins). My Tbred is at a 13.5x multi with the mod. The important thing to remember is to set the Multi in the BIOS to AUTO. A 182 x 13.5 (or 14x) would be nice for ya.

 

[Lyfer]

Whats the maximum multiplier you can access with the XP2600-M?

 

[deadseasquirrel]

I think it all depends on your board. But someone I remember tried FSB as low as 100 and set multi to like 22x and worked without a hitch. It was a 2500+ Mobile, IIRC.

I would just like to hit 166 x 15 (I think 16x would be a long shot) in my KT333 board for now. When I'm ready to move to pc3200 and an nForce2, I'll be able to take advantage of a higher FSB. I just haven't pulled the trigger on the chip yet...

why is everyone wasting thier money on the 2600's?? I have a 2400 and a few of my firends got one also and all are getting 2.4ghz+ I have yet to see that the 2600 are any better

Come'on Blue mod that board!! :evil:

I would, but I used all my funds on a VDD modkit that didn't work.

Actually, Blue, I never saw that thread. Didn't you realize that, since I didn't post in it? You know me. Anyway, 12.5x multi is going to be your max, unless you do the pin mod, but here's how you do it. This way you can't mess up, and it only costs $10. Using wires is impossible. I actually have thinner wires than anyone around here has used, and it still seemed like it had a snowball's chance in hell using wire (to me). Just go to AutoZone and buy a rear window defroster kit. It comes with alot of the conductive "paint", and a thin little brush to apply it with. Use the link provided by deadquirrel, and just paint a little line between the two pins you're supposed to connect. Yeah, I know it might be a total of 10 pins, but just connect them one at a time. And I made a printout of the webpage, and just took it with me, so i could look at it anytime I wanted, just to be sure. I spent over an hour trying to do it with the wires, so I went to AutoZone, and it took less than 60 seconds to do it with the conductive "paint".
edit: Oops, I forgot to tell you, 15x is as high as you can go. Well, there are no working multipliers between 15x and 18x.

i want a mobile barton ...

a nice 2500mhz would be cool. haven't figured out what's holding my barton back ..

PSU > too many hard drives
memory > 2 x 512 Corsair 3200 XMS
mobo > NF7-S rev 2

My XP-M 2600+ does 2.2ghz @ 1.45v, and 2.5Ghz @ 1.65v....I've yet to see a 2400 or 2500 mobile hit 2.4+ on anything under 1.8v...

Edit: And it was only ~$15 more when I bought it.... I don't know about you...but $15 is no big deal. The 2600+ is going to be the "best of the bunch" since it does almost 3200+ speed with only 1.45v.

 

[pamf]

im thinking about getting a 2500-m.. would there be any reason to get a 2600 or something different?

im getting 2.3ghz/400fsb out of an aqxea 2500 right now, on an a7n8x-deluxe.. hopefully i can get something better from the m..

myocardia, the most i can get from my board is a 12.5x multiplier.. its a rev 2.. same thing with the 1.4 ive got here too.. is there some mod you have to do to get higher than 12.5?

i can SET it higher, but 13x seems to mean 5.5x...

honestly i think i could get a hell of a lot more out of this 2500 ifi could bump the multi more.. ive got lots of voltage to play with and the temps are fantastic (35c under load..)

My XP-M 2600+ does 2.2ghz @ 1.45v, and 2.5Ghz @ 1.65v....I've yet to see a 2400 or 2500 mobile hit 2.4+ on anything under 1.8v...

Mine does. I am running it now at 2.55 using 1.85V prime stable. It does 2.5 on 1.8V prime stable. This is on NF7-S and air cooling with SLK-800.
I am wondering if 2600-M is a touch better, if it is I would order one momentarily.

 

[drewdogg808]

i would have to agree that the 2600-m is a hair better than the 2400 and 2500s.

my 2600-m does 2.2ghz@1.42v, 2.3ghz@1.5v, 2.4ghz@1.62v, and 2.5ghz@1.70v aircooled.

seems like most 2400 and 2500 need a bit more voltage to hit 2.4 and 2.5ghz, but are still hitting those speeds nonetheless.

 

[joe2004]

The heck with you man, thow some 1.8 at that, I am sure you can hit 2.6 that way. Don't be stingy!:evil:

No offense man, but what did I say....

You said...

Mine does. I am running it now at 2.55 using 1.85V prime stable. It does 2.5 on 1.8V prime stable.

So, your doesn't hit 2.4Ghz+ under 1.8v..



There is a big difference between 2.5Ghz @ 1.65v vs. 2.5Ghz @ 1.8v...

I personally don't like to go over 1.75 on .13um CPU's...

 

[joe2004]

So, your doesn't hit 2.4Ghz+ under 1.8v..

Yes it does. I incremented to 1.8V because I wanted to go over 2.5, but I can get 2.4 easily with way less than 1.8V.
Believe or not, doesn't matter.

 

[Insane3D]

2.4Ghz+ = above 2.4Ghz


Again...it really doesn't matter, and I'm sure there are some people out there that have the odd 2400/2500 XP-M that can do it. My point is the 2600+ is the best chance @ 2.5Ghz+ with a reasonable voltage.

I enjoy running 2.5Ghz with only a Alpha a ~23 CFM Coolermaster low speed/quiet fan.

Again, no offense.

I'm running a Barton 2500+ Mobile on my Abit NF7-S V2.0. I have it running at 11.5x217 which by my calculations is pretty darn close to 2.5gHz (2496mHz). I'm running it at a voltage of 1.7. I think that satisfies you're

[Darkhawk28]

What HSF are you all using with these Mobile XP's?

 

[kingmike]

I have a mobile 2500+ at 2.5ghz and 1.65 volts and it is perfectly stable

And another! :Q These are Prime 95 stable for 48 hrs right guys?
