i've been reading how everyone likes their mobile 2500 processors, and went over to newegg to check them out. I read a lot of the reviews and most people seem to be doing 200x11 (3200+). Well, i get that now with my tbred 1700, (that i paid $42 for) so should i splurge for the new processor? my FSB will only go to about 217 because my ram is only pc2700. What does everyone think?

Virtually all 2400+ mobiles now do worse then they used to. Expect 2.4 GHz with 2400+ mobile.

With 2500+ or 2600+ mobile you may get lucky and hit 2.5 or above.


You'll also have double the cache of your 1700+.


Is 2.4 or 2.5 GHz with double cache better then 2.2 GHz?


It is if you can sell the old CPU, get the new one for little $ difference and install it quickly and painlessly without frustration or complications/ ;)


My transfer from 2.3 GHz 2100+ B to 2400+ mobile wasn't as quick or painless as I thought and would have liked.

The 2400+ you are talking about is that the one in your sign? Cos I've ordered exact that stepping but still haven't received it yet. I'm very anxious to see what this chip can do, but see that you have it only at 185 fbs now. How come?

We can post in the thread about that 2400+:
http://www.ocforums.com/showthread.php?t=305940
so as not to hijack this guy's thread but my conclusion since making that purchase is that most newly purchased 2400+ mobiles do less than 2500+ and 2600+ mobniles now.

They use to do better but there's a growing trend indicating most of them were now labeled as 2400+ because of their performance and not just marketing reasons like when they first came out.


The asnwer to your FSB question is:

Generic average overclocks:

PC2100 form 133 FSB to 140 to low 150s FSB, 100% insync.
PC2700 from 166 to 180 to low 190s FSB, 100% insync.
PC3200 way into 200s, depending on brand.


I have PC2700 RAM capable of low 190s at the most. I dropped the FSB down a little because it's summer and the temperatures in Kansas are very hot, I'll probably go back up when it gets cold here.

Also I need the wire trick to go above 12.5 multiplier so I would have to go through the hassle of getting the wire out of the socket to do the same MHz I have now with
185 x 13 = 2405
vs.
192 x 12.5 = 2400

and 192 is on the edge of what most generic PC2700 RAM sticks are capable of.

That would be why.

I've noticed people reporting this too. I wonder what's been going on.. bad batch from AMD or something?

I've heard VERY good things about recent batches of XP-mobile 2600s.

I went from a 2200 to a 2500 mobile. Absolutely awsome.

Pretty damn worth it, I think. :)

well i got the 2500 and it's humming at 2300 (11.5x200) but i'm still not dome pushing the multiplier. i'm stuck at 200 FSB because my 2700 does not like being pushed past this. but for 2700 i guess i can't complain.... lol

Samsung PC2700s are the exception. Almost all Samsung PC2700 go into 200s with enough Vdimm RAM voltage. What is your Vdimm and Vcore voltage?

I agree with 2600's on the average being better overclockers. Maybe AMD has a new screening process....

As mentioned before by others certain steppings seem to be better than others. IQYHA being one mentioned most often. I have a IQYHA at 2.5GHz (12.5x200) using only 1.65v. It can go quite a bit further...
