TBred B XP2100+ works GREAT on KT7 non-A without ANY mods!! Running at 2.3GHz now!

[Xenon74]

Ask them I guess!

It is getting rather hard to find unlocked Tbred B's i wonder if Mobile xp's would work? or will we have a problem that the board vant drop the voltage that low?

 

[Xenon74]

Teoretically they should work.

I flashed to the A9 bios a few days ago now my idle temp is 10° higher then what it was with the UL bios, do i have to enable some acpi "cooling" option in the bios or something?

 

[Xenon74]

10° higher!!! What type of processor do you use?

 

[UnL0GiC]

Problem solved, had a little issue with the sun from the window hitting directly on my radiator

Btw the cpu is an 850 tbird @ 1000 fed with 1.85 v ...i just managed to get hold of a unlocked XP 2400+ but i dont really have the time to mess with that right now

 

[Xenon74]

have fun and keep us informed.

Seems like i was abit wrong about the sun there, this bios cleary changed something cause my idle temp is just 2° lower then my full load temp. Seems like the acpi HLT command isnt working :-(

Any hint on what needs to be changed? I tested some program called Vcool but i didnt change my tempratures a bit.

 

[UnL0GiC]

Okey problem finaly solved the problem, i just had forgotten to reset the bios after flashing the A9 in

 

[Xenon74]

hehehe

For all of you who go from an old bios to a new one like A9 you should be aware of this:

Why is my idle temperature so much higher under BIOS version 3R or later?

With previous BIOS versions ABIT set a bit in the BIOS CMOS (offset 52 bit
7) to "1" to enable the ACPI "HALT" function and cool down the CPU temp in
idle mode. This, whilst allowing cooler CPU operation, is against the
advice of AMD and VIA. Under earlier AMD processors, however, this
modification allowed the system to idle cooler and had no ill effects.
However, it was been found with newer 133MHz FSB processors running at
1333MHz and higher, that this software cooling can cause severe stability
problems - especially under Windows 2000. As a consequence, in all ABIT
BIOS releases after version 3R, ABIT have set this bit to "0" - the value
recommended by AMD and VIA. This allows the motherboard to be stable with
all AMD processors at the expense of an increase of 5-10 degrees
Centigrade during idle (from approximately 35 degs C to 45 degs C). This
will not harm your motherboard or processor. Note that this CMOS setting
is widely used by other KT133/KT133A based motherboards. Note that if
your processor is slower than 1333MHz then you can revert to the previous
setting of the BIOS by using H-Oda's WCPREDIT and WCPRSET programs to
modify this register value. If you are using Hex mode in these programs
then change register 52 from 6B to EB to re-enable the software cooling.

Ok guys here it is!

Installed my xp2400+ today set the multi to 9x and it booted up fine

Next step was 2300 at 1,85 it managed to run 3dmark but it wasn't stable in prime95 so i backed down to 2200 and it seems to be rock stable at this speed

My sandra cpu scores more than doubled and my 3dmark 2k1 went from ~5500 to ~8500

Here's the system spec and a pic of the cpu:

Abit KT7-R, 2*128+1*256 ram (at cas 3 sadly), Gainward GF4 Ti4200 (301,603), ...all watercooled.

need suggestion

I have kt7a-raid w/A9.
As I'm a member of the brotherhood I need suggestion.

Which cpu should I get? As I see, I cannot go for a cpu with 333fsb. Our 266fsb contestants are,
unlocked 2400+ tbred,
locked 2400+ thorton,
locked 2600+ barton.

Even tough its locked I'm thinking to go for 2400+ thorton.
I can 15x140 and unlock for 512 L2 cache.

So should I consider an unlocked 2400+ tbred for more clock speed or 2600+ for being a barton.

I could add mobile versions but bang for the buck is my intention. I will be selling ayhja 1400.

 

[jtf2]

Im running my 2000+ at 2.35ghz and trying to get it stable at 2.4ghz.

Hi folks,

just got a T-Bred B 2600+ (266) unlocked running smooth on
my KT7a V1.0 with Bios A9 beta

Clocked it with 17x133 (9 in fact) at 2266Mhz @ 1.725V without probs.

It's a week 0345 unlocked JIUHB
AXDA2600KV3C
JIUHB 0345 MPM

So far CPU on Board History:
1000Mhz T-Bird
1200Mhz T-Bird
1400Mhz T-Bird
1800+ Palo
2000+ Palo
2400+ Tbred B
2600+ Tbred B

Congrats!
Nice work and quite a history for one board. "Tried you beyond 133 have?" (hehe sounds like Yoda)

[Olio]

Hmm, no, unfortunately every attempt to raise the FSB
to anything higher than 133Mhz result in sudden crashs
within Windows, even with VCore Voltage of 1.85V, doh.
Tried it with 136/34@2320 Mhz. Any idea?

Think I'll stuck on 2266Mhz

 

[Xenon74]

Nope, but Ich habe the same problem. I can go beyond 2267 with multiplier only. I think that's the problem of Kt7a v1.0 mobos, and not problem with wrong settings or something like that. I've tried several BIOS versions and practically all available settings but no success!
It's kinda frustrating: I have this mega 2100+ that goes beyond 2.4GHz on air but I cannot OC it. I can only raise multiplier at default FSB. OK that still qualifies as OC but still....

Hi to all!

First post here.

Got a xp 2500+ @ 2000 MHz (20 x 100)
and 2 (yes, TWO) GB of RAM on my KT7 non a.
Tried three sticks of 1 GB and it worked, but could keep just 2 of them.

The only problem is i can't get the ram to work at 133 mhz, just at 100.

What to do, oh what to do?

Any suggestions appriciated.

Thanx and greetings!

Odradek

Hi again!

Seems like my first post in this great thread is the last post in this great thread. May he rest in peace...
