I have a Abit AT7 MAX2 with 2500+ (week 33 so not locked)
ddr 400 (el cheapo) but the board is only running it at 333 also
a 9800 pro 128mb video. The and NO PCI cards at all. so no worries with
the pci bus. for cooling i have a Zalman cnps 7000A-Cu *copper*.
my question is
when i change the multiplier to 12x the system wont boot, do i need to
change the voltage? i know a stupid question but i have not found to
much online as far as details on overclocking. "how to" my board will go
to 22x. I can get it to 2.2 with just changing the fbs to 200 but would
like to go more than that.
what is the most that someone has o/c this thing to, ive heard numbers
like 2.8 3.0 and even 3.2 ( is this posible with air?
Thanks for any help

Hi,
running a XP2500+ (Barton) at XP3200+ speeds (2.2GHz) is about the best
average overclock. Some have 2.3GHz, 2.4GHz and even 2.5GHz (quite rare).
The best I can get is 2.3GHz but it requires *allot* more voltage to run
stable at those speeds. . .

12x166 is only 1992mhz - yet you say you can do 2200mhz on stock voltage -
never tried running mine on a (assumed) 100fsb and seeing if it requires
less volts.
Is that right - you can get to 200mhz fsb on a KT400 chipset!!?
- or do you mean with the fsb at 100mhz - even without pci cards I would
have thought it would still fall over at or before 185mhz
I would try upping the vcore to see if that lets you get 12 x 166
i know a stupid question but i have not found to

suggest upping vcore (maybe 1.85v) and trying 14x166 and setting the cas as
low as you can - should be able to get cas 2.5 - maybe not cas 2.0

no - not in mhz anyway but xp2800+, xp3000+ and 3200+ is easy
a bit over 2500mhz is about the best you might achieve - which on my kt333
chipset needs 2.1v vcore - which pushes my xp2800+ rated £6 hsf quite a bit
(60C+ on the diode on full load) - and this is in the winter - in the height
of the summer it can not cope and diode temps go over 70C

The most you can hope for on air is around 2.5GHz, and to achieve that you
will need VERY good cooling, an exceptional CPU, and over 2.0V. I'm running
at 2.5GHz right now but I've got an SLK900u HS with a Delta 120mm fan, I've
gone through about 8 CPU's to find one that hits 2.5GHz and it still needs
2.06V (mine is week 34 by the way)
2.2 to 2.3GHz would be a more realistic target.
2.8GHz is for the refrigeration (phase change) boys (if they are lucky) and
3.0 - 3.2GHz is really just dreaming...maybe liquid nitrogen would get you
somewhere close but I'm not so sure.
Your board will not do 200MHz FSB(400DDR) without putting ALL the bus speeds
out of spec i.e. AGP, IDE, USB and PCI...Just because you don't have PCI
cards does not mean you can run 200MHz FSB...It's possible that you will be
able to but it depends on the tolerance of your hardware to an overclocked
bus, especially the graphics card and IDE controller, try it and see.
Your other problem is that your board is unlikely to have '5th bit'
multiplier control. That means that with a CPU that has a default multiplier
of anything 12.5x or below the maximum multiplier you can select without
physically modifying the CPU would be 12.5x.
Having said all of that you should really be able to up the multi to 12x no
problem, even without increasing V core. I'm unsure what the problem is
likely to be...you could try upping the volts but it really should not be
required for a mild overclock such as this...does it do 11.5x ok ?
Sorry but my advice if you want to do some serious overclocking would be
invest in a new motherboard...you can get an Abit NF7-S V2.0 for a very good
price and this would let you run 200FSB and over, plus it would let you
select any multiplier you wanted.

I hope you don't think that the PCI bus is only for the card slots. |
Almost everything also runs off the PCI bus.

That's because OC is simple in it's basic form. Mult. x FSB = CPU speed. |
When your system didn't boot at 12x200 did you raise vcore?

Only a 300W PS with that vid card? If you want to overclock higher, get a
400W PS minimum.

Your system temp cant be higher than the CPU...the readings must be
reversed...if 50C is idle temp then it's way too hot. Try load testing with
Prime95 and see what temps you get then.........1.9V is safe *IF* you can
keep it cool.

Actually, I've seen screenshots at 3.6GHz with LN2 and 3.3GHz on dry ice.
Obviously not stress-tested at this point though  With "good" Bartons,
2500 seems to be the limit for air, 2700 the limit for water, and 2900 for
phase change. Talking prime-95 stable that is. I've seen a CPUZ shot of a
phase change setup at 3.1ish GHz, but there was no mention of stability.

i thought that they were reversed but thats what the program says;
I was using prime95 and they didnt go up from what i saw untill it crashed.. |

Don't know, but I'd expect it to be somewhere around the -40 to -50 deg C
mark.

What motherboard? It's usually best to get the FSB as high as you can
and perhaps even lower the multiplier if the CPU becomes the limiting
factor. Both FSB and Multiplier speed up the CPU, but the FSB speeds
up the whole system while the multiplier only speeds up the CPU.
What is that system temp and cpu temp about? There should be diode,
socket, and case, no? Others also but it doesn't make any sense that
the case temperature is lower than the CPU unless you are
watercooling. |
