already stated at the early post - it is 1003 CPMW with alphabet "T" on the pcb.

that's one hell of a batch... 4.3GHz capable w/ right kinda hardware combination + hardcore tweakin... drool.gif

but NB freq the higher the better..ofkos it have its optimum value for CPU speed vs NB freq.. but the main idea is higher is better...with deneb c2, 2.6ghz not a problem with stock vnb..the c3 i donno..2.8ghz?
not really bro, imc differ from chips to chips. 2.6GHz is doable on c2 but not all w/ stock volt, some even top up @ 2..5GHz ish regardless what kinda volt pumped. same w/ 2.8GHz on c3, not all is capable doin that w/ stock volt. out of 2 chips i've tested, both max out @ 2.7xGHz w/ moderate volt (<1.4v), 3GHz is a no go regardless what kinda volt i gave. smile.gif

2.6ghz fail after 15minutes of prime95 for stock voltage.

i think i'll stick to 2.4ghz for now.

is that big different between 2ghz and 2.6ghz?
i ran Pi, fritz chess benchmark and 3dmark vantage, seem like not much different.

yeah...i was wrong about that... sorry tongue.gif tongue.gif rusted over here..
too long havent OC... when i check back last night my SS's, its 2.4 only...2.6 obtainable with alittle increment of vnb..

so did told hilmiangah about this as AMD OC thread..

decent batches of c3 can do 3.6GHz @ 1.3v or below on decent board, while for c2, some managed w/ only slightly > 1.3v. mobo does play a big role there, but as we all knew, software reading not always d most accurate source, d only way to find out true value is to have it measured usin dmm... smile.gif

1.344V VS 1.38v not so big diff, some more c45 is value board, can't really compare w/ mid range/premium boards. my ex g45 (yes, i'm sellin it tomorrow) has voltage fluctuation issue. auto 0.05v increase from idle to load. sweat.gif

play w/ spu voltage enuf... u can always set d desired voltage & check in bios. smile.gif

This morning i'm wasting my money to buy AMD Phenom X2 550BE @ 3.1Ghz.

The price only RM315 OMG!! Damn cheap..(anyone interested let me know tongue.gif)

My batch number (i think my batch is the 1st to unlock here, so far laa..) Batch # 0931DPMW, yes 0931DPMW unlock to 4th Core without any error.

Haven't done any stress test yet, but i will try to keep update here.
