what about 300MHz+ HTT on that one

Almost the same...27C less:)

im confused, thats still stock speeds?

Yeah, but look at the temps. It actually booted into windows at that temp. most wouldn't even post at those temps.

That chip will clock a lot higher he's just showing the temps it can withstand.

I think you're missing the point Kyle ;) The comparison is done to show if the cpu can do higher HTT's at lower temps. The lower the temp, the more difficult it is for MOST cpu's to raise HTT's....

But didn't he just post 200 HTT? I guess I missed something, sorry.

He did post 200HTT, but look above to my post - 250HTT @ -98C ;)

Oh, I just ignore your posts now, because I'm tired of my eyes bugging out of my head. ;)

Is this good enough for you? Bench your 4600:)......

Most, if not all FX60 XXX2E won't even post @ this temp.....4 leds on.

Dumo I knew this thing was going to rock after you posted your SS at those temps in windows. Now I've got to ignore your posts too.

Damn you and stephen; now I've got to get something that's not bugged. Maybe one day I'll get lucky...;)

LOL...ok that's better :toast: As for the 4600, I won't have it until later on this week, but even when I do get it, I can't get as cold as you :p:
FWIW, the 4600+ was PCMark stable on a stock Mach2 @ 1.536 Vcore @ 11x290 1:1

Nice 4600 there Stephen:toast:

I'm just feel better that finally I can put some serious heat load to 'idle' cascade:) ...after tryin' so many cold bugged cpus that won't even post @ -90C and wasting a good amount of thermal paste:(

Hehehe...IIRC, you've got that big TUB of thermal paste :p: But I bet that 4800+ puts out enough heat that your cascade has to really work to keep it cold ;)

Steven, have you, or anyone else had a chance to test Steppings with a BF mem controller under phase, I believe its a new revision, havn't seen it before till just recently....But with the b2's and b3's doing so poorly...I don't have my hopes too high...

I just got Opty 146 from retailer today. Seems like new chip.
OSA146DAA5BN
CACJE 0604CPAW
Has anyone tried out this chip.

How far is this stepping going?

Should be good on air/water, horrible on phase ;)

Hi,

With regard to K7 procs, I read ages ago that the first letter of the five digit code related to "How close the cpu was to the center of the Die". I'm not really sure what that means ,but I alway though that the best overclocking K7 chips' code started with "A" eg AYHJA and therefore "A" was the best produced chip from the production run.

I could be a million miles of topic here but HTH's

Very interesting, I cant wait to see where this research goes.

Logically that has to be an urban myth as if you think about it typically the first letter usually only has 2 variables and often just one. E.g Mobile bartons for a given voltage and frequency were either an "A" or an "I", standard palominos either an "A" or a "R". So its impossible for just the centre of the die cpus to be denoted an "A" (unless it is a very big centre!!! lol).

ok then. this is very intresting, and also depresing. ive killed 2 BH chips :( botched IHS removal.

ADA 3700 DAA5BN
KAB3E 0548 RPCW

this one got the cold bug at 3170mhz, and it was worse with lower multi's, but i managed to get a bench at 3310mhz by pulsing my water pump. this is with the cpu reading 6*c idle ( crappy chiller ) and with any voltage, it dident care what voltage it had, it just took it and went.

ADA 3800 DAA4BW
LBBWE 0532 CPAW

this was a crap clocker. max on air was 2.7ghz, max on chiller was 2.7ghz. it refused to go higher on any setting's. and it was unstable at any speed, including stock. kept comming up with memory errors.

CCBWE 0602 BPMW

this is my 165.
it got to 2.78 on stock air, stable, and 3160 on chiller. but wont go above this, it keeps comming up with memory controler problems. even with negative temps. (-8*c peltier on chiller)
now if i could unlock the multi id push it some more.:D

My 4600+'s, which are the earliest documented X2's, are both TRUE manchester cores with the "D" notation. The prime examples of the "C" 512K l2 x2's are the recent 3800+'s - many with the stepping CCBWE.

They seem to exist eh? :) This one is an even later sample than yours.

AFIK, FCG had a 0519 ACBWE, and this is a little earlier than that.

Does anyone know all of the memory controller ID's as in B2, BN, and which ones don't have the cold bug and overclock best.

Your best bet is with a manchester with the mem controler revision of BH.

Thanks for the "decipher"

I might buy a FX-55 (die is 130nm, clawhammer) for less than $400. Stepping:

CAA2C 0505 DPMW

I have a mach 1, any experience under cold with this specific stepping?

I couldnt make my computer stable more than 275fsb with my opty 146 cabye 0540fpmw under mach1 (r507) (it is windows stable 9x322 or prime/games stable 10x290 on AIR).

Thanks...
