Is this a good 2600+ chip?

[Serp86]

Ok - the serial number is

AXDA2600DKV3C
AIUCB 0308XPMW

How high can it go?

 

[bjc112]

Well it is a T-Bred "B"

You will get a good bit of head room out of that chip...

Check CPU Data Base

 

[Serp86]

the only result is;

2500mhz, voltage: 1.78, code: AIUCB, motherboard; Enmic 8TTX3+ Raid, cooling H²O Selfmade, status: stable, id: 19546

I have aircooling (coolermaster HAC-V81 X-dream variable), and wouldn't want to up the voltage that much.

My voltage is at 1.750... no problem with taking it that high... I just don't like to go above that, or definately above 1.8

*EDIT* XP2600's aren't really known overclockers though... people who buy those aren't buying them to overclock... people buy the XP1700, XP2100, and XP2500 mainly for overclocking... some buy the XP2400 to ensure it's a T-Bred B core.

i see.

Since i have it, i thought might as well try to whip it

Anyways - it booted fine at 1.65v 133x18 - 2394mhz - but when i tried 133x19 1.65v, it booted, but windows startup screen never appeared - should i up the voltage? By how much?

Then i tried 1.65v 166x12.5 - 2075mhz - rock stable (by the way, i don't know if it's 266 or 333 fsb - can anyone detect it from the code? thnx)

then 1.65v 166x13 - 2158mhz - stable
1.65v 166x13.5 - 2241mhz - stable
1.65v 166x14 - 2324mhz - BOOM - no boot (cpu not fried - just won't boot - whn i relaxed a bit after a cmos clear it booted again at 166x13.5)

Would upping the voltages help?
Also, from the code, is it 266 or 333fsb?

 

[bjc112]

Yes up the Vcore to 1.7 or 1.75.. Also upping the Vdimm ( Memory voltage to 2.7-2.8 will help)

looks like you got a decent chip.

 

[Serp86]

166x14 @ 1.725 OK
166x15 @ 1.725 NO BOOT
170x14 @ 1.750 OK (currently here @ 2385mhz - sandra shows my cpu is equivalent to a 3600+ - it's beating the wall with the 3200+ !!!)

 

[MDE]

You got one nice chip my friend! My 2600 wouldn't go past 2.25 and it still wasn't stable at 1.85V. Hopefully my new 2500 can beat the wall with yours...

 

[Serp86]

what was strange is that temps went up by only 5 degrees from 133x16 to 170x14! I am still using air cooling

 

[bjc112]

I am running a 1700+ @ 2.425 ghz... 210X 11.5

1.75 vcore... .

45C full load.

 

[Jeff7181]

Best way to tell if it's 266 or 333 is set the multiplier to "default" and see what it sets it at.

Try running 200x12 and see if you can complete at least 15 minutes of Prime95 without an error.

 

[Serp86]

OOPS - forgot to mention i'm on a KT400 - ABIT KD7

There's no way in hell that i can run it at 200 fsb - and i can't afford an nforce 2
