all XP-M2600+ users, need your help

[naelq]

hi there all,
i have an IQYHA MPMW chip that clocks very good, (2.7GHz @ 1.825v) but the problem is that chip, no matter what FAB/multi. combo i use limits at 2.8GHz total speed!
now, i need your help to solve this problem, if i may call it!
my system specs:
> XP-M2600+ IQYHA MPMW
> NF7-S rev2.0 with D22 Alpha1 BIOS (posts at 250MHz without any problems, & doesn't have any volt-mods)
> 2xCorsair CMX256A rev1.1 BH-5
> crappy 510W PSU, will be replaced very soon with a 530W Fortron
> TR SP-97 + AS5 + 92mm Enermax / 92mm TORNADO

now let's start with the MAX speed you could get with ONLY AIR COOLING, & with which MoBo/BIOS/HSF/RAM/PSU?!

PS, i'm aware that there is a thread about Mobile chips, but it's not a dedicated XP-M2600+ one, plus it has a lot of OFF-TOPIC...


thanks in advance,
NaeLQ

do NOT be angry with ur limit at 2.8ghz, thats because of ur cooling.

ur VERY lucky to hit that high on air, so dont be mad at anything

tell me something that i don't know!

blinky. thanks for the input!
but i wonder, if a decent WaterCooling system will help??!

[Poki]

I really doubt water is gonna help much. To get much a boost you'll need to goto phasechange.
It's a good chip for sure, be nice to it.... Don't kill it making it do stuff it doesn't want to do

[naelq]

that's what i didn't want to hear!
let's wait some more time, maybe someone will help!

I think you may have a point if you've done the L12 mod.

I can do 12x235= 2820 Mhz rockstable on air
Screenie
2600+ MPMW 0352
NF7-S, 2V vcore, SP97, ANTEC TP

12x238 is Pifast-able but higher is no go
This with APIC ON and no L12 mod

BUT ... I have the same problem when I did the L12 mod. My max FSB is higher but the total clocks do not go over 2.8Ghz
Screenie (pifast at 2.8Ghz)

[naelq]

L12 mod is done, sorry for not mentioning it before!
now, with the L12 mod enabled, i can go whatever FSB i want, i can boot with 250MHz FSB, but the RAM needs more voltage. without this mod the MAX FSB i can get is 217MHz, but still the overall speed is ~2.8GHz-2.85GHz even with the 200MHz FSB!
what temps do you get?!
since i have the SP-97 with the 92mm TORNADO, MAX temps are 47C - 49C with 2v vcore.
i don't know what to say! maybe it's chip's limit.

BTW, any XP-M2600 with WaterCooling?? mabe the things are better? (although i believe not!)

[Lithan]

No. Xp architecture wont get you much above 2800mhz without supercooling. I've yet to see any AMD do more than 2800mhz stable without subambient temps.

[naelq]

that's good!

[HaLDoL]

So, the overall clocks do not benefit from the L12 mod. That's an interesting finding. I wonder why. Maybe this something for TicTac to look at.

Lithan: a lot of people can reach more than 2800 Mhz without supercooling. I think 2.9Ghz is the border now but maybe with newer mobiles and new mobo's (nf2 Gb?) people can reach 3Ghz on air.

Mine is really rockstable at 12x235 (25°C room temp gives 40-42°C stressed).

[PureBooYah]

I have the exact same chip, exact same batch info...most i could get out of it was 2.7ghz (11.5x235) on my DFI infinity with 1.9v...cooling was SLK900 with a 50cfm Sunon fan. Max temps were around 50-52c. Anything over 2.7ghz and it was unstable.

[naelq]

but still, we need someone with the same chip & yet WaterCooling setup!

[Poki]

I can tell you what my temps are on mine with an infinity.
With 2.0v selected my diode temp is obviously wrong (highest peak i've seen was 82f) but my system temp is 92f and cpu socket no higher than 93f.
This is with a dangerden maze3 WB/ little giant 475gph pump/ chevrolet s-10 pickup radiator with 30 inch box fan. Ambient temps around 75-77f.
I have a panaflo 92mm blowing on the video card and a 120mm NHB blowing on the cpu/memory area.
I had very low peak temps on my NF7-S also. Highest cpu temp i recall seeing was 109f with a m2500 and m2600 2-2.15v around 2700-2800MHz.
No direct help to you but you can see watercooling helps keep temps in check.

I've yet to see anyone hit 2.9ghz 100% stable on air. And I will guarentee that noone has hit 3ghz stable on air.

I'm stuck at 2800mhz due to my boards OVP kicking in at 2.0v. But 2.633-2.800 takes an additional .275v, so I suspect that even 2.2v wouldn't get me 2.9ghz. And any higher voltage and you'll start having temp problems on air (unless you are in subfreezing ambients which is cheating.)

[tylerhskate]

your getting a little too extreme, i mean be happy with 2800mhz - after all it is only air :O

[naelq]

tylerhskate, true! 2.8GHz isn't bad at all, but i'm trying to help myself deciding if to go WaterCooling or not!

water cooling will not help you unless you chill the water. 2800mhz is awsome man. this chip here that im getting 3gigs out of using phasechange would do 2700mhz on air. now think about it man i went from 2700mhz 1.9v on air @ 40c to 3000mhz 1.95v/2.0v @ 3c ( atleast thats what my bios and winbond report it at?) that is a big ass temp change for what 300mhz? now what do you think 36c water is going to do for you that your not already doing on air?

now this is just my 2 cents to maybe make you see things another way so dont get all bent out of shape on me. just tryin to help. good luck man and BTW one kick arse oc you got there on air!!

peace perc,

[naelq]

ok, then i'me not going to invest on any "fancy" WC setup or phase change, you've convinced me!
but i'll continue my WB project that i stopped last year, so now i'm going WC just for reducing the TORNADO's noise!
& yes, i don't think that those extra 200MHz-300MHz worth it, eh?!
right now, i'll concentrate on modding my MoBo maybe in Tuesday, so let's hope i could finally use windows @ 250MHz FSB stable after it!! (the MoBo does boot windows @ 250MHz but the RAM, BH-5, needs lot's of juice for the 2-2-2-11!! BTW, does 250MHz @ 2.9v vdimm @ 2.5-4-4-11 in DC but windows not stable!)

thanks
