3.0C SL78Z L349B = 3.75GHz @ stock

[Sin22]

I know a few people have been asking about this stepping so I spotted one today and decided to give it a shot.



Plugged it in and poof:



At stock volts, using a Cooljag CJC661CA HSF.

My P4P800 detects its stock volts to be 1.55v though I have heard of these doing 3.75GHz @ 1.5v.

Time to chuck this on the phasechange and see how it likes some cold loving.

one good clock! maybe I will hunt one down here in Norway.... hmmm...

[bigjohns97]

where did you find this one at, do you know of anywhere else that has them retail?

EDIT : is there a bios update for your motherboard?

Nice, I called excaliber pc but they didn't have any in stock. I'm getting an sl6wu instead.

Nice OC. I've been looking for these SL78Z for days now and haven't spot any yet. Where did you order yours from?

I've try 4 SL6WK 30 caps, including one with batch# L349A726 and none of the 4 can do 250fsb at stock voltage.

Is that 100% stable at stock voltage?

Sin22,

Sweet Stock OC!

Let Us know how it does in the Cold Zone.

I've had three 3.0Cs thus far.

1 SL6WU L348A (12 caps) did 3.6GHz @ stock.
1 SL6WK L348A (30 caps) did 3.75GHz @ stock.
1 SL78Z L349B (30 caps) doing 3.75GHz @ stock.

But this one is better than my SL6WK. I put in the droop mod when I bought it so the voltage variance is less, including the overvolting which indicates a better o/cer. It can do up to 3.8GHz @ stock.

I got these here in Singapore mate, few shops carrying them and to my knowledge another guy here has had the same results.

I'll get this under the PhCh system ASAP but there are some issues I need to iron out first as I mentioned in my PM to you hallowen. But I'm willing to bet at least 4.2GHz out of this guy.

hehe sweet. I've got one of these and I can get it 4ghz on air - 3.88ghz stable at about 1.6v.

Edit: SL6WK L349 12 caps - 3.88ghz stable at 1.6v on an Asus P4C800-Deluxe.

I thought the SL78Z was an oem cpu? At least it said so on the spec finder when I last checked...

I want a good chip. I seem to be stuck at ~250 fsb with all of mine.

thats no wonder
see it

[bigjohns97]

have you put it on a prommy yet ?

[MAJT]

I got a SLWU and I cant go past 3.6.... I pray to god its the mobo holding me back cuz I might get an IC7 for some better oc's.

[ibby]

ive just bought a 3.0 c .... dont even know what stepping it is ...
how many caps ... iam just trying on my luck to see how it goes,

My 3.4 on air isnt very impressive.
