Weird Problem: A64 CBBID stepping and MSI K8N NEO4 Plat Board

[gsethi]

Ok people, I found a weird problem with that combo. Tested it with 2 different CBBID 05 chips.

When overclocking, your board wont POST past 219FSB. It will post at 219FSB but wont post at 220FSB. This is using the 4x HT (which means 220 x 4 which should be fine). No matter what you do, no matter how many volts you give, it just wont POST at 220.

The trick is to lower the HT to 3x and then it posts fine. I have tried it with two different CBBID 05 chips and same results with both.

My other chip:
3200+ CBBFD boots fine at 250FSB x 4x HT but not the CBBID
CBBID boots fine at 260FSB x 3x HT.

So all those people who are thinking that their CBBID chip is not a good overclocker, make sure to lower your HT to 3x and then try overclocking.

This may also affect other nforce 4 boards also.

PS: Please post if this fixes your overclock problem.

Thanks! I sold me 3000+ winnie to my bro and got a cummy CBBID 3200+ Winnie and have had terrible OC results, and this might shed light on why. My old 3000+ winnie could do 280FSBx4 HTT no problem but this one can't even come close.

Question, just how much does the HTT speed affect ACTUAL speed of the machine?

I have a Winnie 3500+ With this stepping, and I read some information about this stepping and is a more over oc'ed processor, not is the very best, I use mi AMD with stock settings and I no had a troubles.

Hmm,... dunno. I just picked up a Winchester 3000+ CBBID and it'll post at 236 fsb, 4x HT, and a 1.425 vcore.

My 3000+ CBBID 05 Winnie runs stable at 225 MHz with 4x HTT multiplier

Haven't tried any higher yet.
