what alllowed you to go so high?

PICKED OUT THE CHIP FROM HUNDREDS OF YONAH :p:

amazing score...did you also change the jumper settings as what some review site did to get past the FSB limit? can you share that jumper settings?

I've tried.
leave J4 and remove J5.
but...no use at all.
still post and max at 255fsb if not use the remote control.

I think the FSB is highly related to the Temp.
Lower the Temp / Enhance the CPU cooling make my T2400 runs higher.

Thanks a bunch, bookmarking this as none of the site mentioned about that Jumper settings. However, GamePC mentioned two(2) jumpers and not one. Maybe you can try changing both jumpers as what GamePC did.

Here's the linky (http://www.gamepc.com/labs/print_content.asp?id=coreduo&cookie%5Ftest=1&MSCSProfile=95385A1F52DEA1A229D5B375420544646BDE7E 9C061718674AC312C58AE179866CCFCA4CBE26398D60E5CE32 440F57135BB110715559B8AA34A41FBC83C2E518574537F513 298B25B3C25BDB32390390BEC4038080B986A063A6B71E6F6C B36F8DEAB3711FC233F60E670A689EFA4073C15E51044BF294 2A30CEAE6BE86C7360E1DF6D5130DA11BF):

With the removal of two jumpers, this AOpen motherboard does allow FSB speeds up to 1066 MHz FSB. Using this technique, we were able to overclock a Core Duo T2600 (2.16 GHz) to 2.9 GHz.

Again, amazing results. Good to see you back from your business trip and making and posting benchies again.

I agree. I've noticed that the core temp varies from one Yonah chip to another, even when using the same VCore.

Nice overclock, by the way. :toast:

The two jumpers are mentioned in the motherboard manual. You remove both to overclock.

remove both to 200fsb.

heard from AOPEN's RD that J4/J5 is for 1066fsb (future CPU in the next year).
so...I've tried several combination. but all failed.

[death metal]

edit: answered above already, thanks guys!

hmm, I don't have an AOpen (yet), but I never thought they were mentioned in the manual woot..tnx.

[sierra_bound]

remove both to 200fsb.
Technically speaking, you are correct. But as anyone who has the board knows, you can set FSB well past 200 in the BIOS. And of course, there's the remote as well.

You mentioned picking this chip out of hundreds of Yonah's. What was the average FSB speed of the T2400's you tested.

remove both J4/J5 , you start at 200 and max 255 in the bios.
if not, start at 133 and max at 199.

T2400, 240~270 average

Yes, I know that. But thanks anyway for the clarification.

So the T2400 is like the T2600. All over the map as far as maximum FSB. Interesting. Thanks.

Nice !

What 6800 GS is that? eVGA? How did you get it to such high clocks?

[VictorWang]

that's a gigabyte 68gs.
i did the vGPU, vRam mod.
it's benchable at 656/1320 with ICY-WATER cooling. 608/1320 with NV5 AirCooling. ;)

so, 555/1260 is just a piece of cake.
I have to ensure the stability and just wants to see what's the highest fsb benchable for YONAH on AIR.


this is the prime testing:

whats t2400 max multi?
can you run it @ lower fsb but higher multi?

[VictorWang]

Yonah is a chip that highly temp sensitive.
lower the multi with no use or do higher the volt.

Nice!!

wow.. 277.. can only dream of it.. :(

Hey Victor.. if u got some time.. vdroop is needed.. can u help?

[VictorWang]

Nice!!

Hey Victor.. if u got some time.. vdroop is needed.. can u help?

i aslo wanna find out a way to fix that problem :(

[[cTx]Philosophy]

Impressive :P
higher multi @ 277???????

[Pt1t]

Impressive :P
higher multi @ 277???????

:fact: highest multi on T2400 is 11X :d

[200%absolut]

i have 3*2400 retail to test this week :D really nice score ;)
what's the stepping ?

[VictorWang]

lower the room temp to 20c

max at 279fsb , 278fsb saved a cpuz file :D

Agree with you :toast:
