4200+ 939 stepping

[Sean_UK]

Hi, just picked up two 4200+ 939's for two builds I’m doing, wondered if anyone knows a good link or perhaps has some experience with the below CPU batch(s).

-LCBKE 0643TPMW -Y974284k60784
-LCB9E 0643TPMW - Z760464J60098

Only ask as one's going in a gaming PC which I’m over clocking a fair bit and the others just an all-rounder that I dought ill be over clocking - so would like to get the better suited chip in each PC if you see what I mean. Far as I’m aware the CD or BV on very top line of chip ID tells you if it’s a Manchester or failed Toledo, these are both showing as CD which is a bonus I would think?

Comments as always appreciated.

Well ive done a cpu-z using an old 939 mobo and they both show up as Toledo's, cant do much else with them till the actual mobo's they paired with turn up.

2.75 both so far on basic quick play (250x11), so not bad and will tinker with them futher once i get the builds fully up and running. Found some info to suggest the LCBKE will do 3ghz no problem, maybe two good ones then, result! Good job i suggested some Scythe Infinity cooler's to go with them at the time of purchase incase they clock well...

Is that on stock vcore ?

Yep stock vcore, both now on 2.8, left over night stress testing, no problems so far. Will try for 3.0 if this dont involve large increase in vcore, which i dought going by results so far.

One wont do more than 2.85ghz without getting silly with the extra volts, other will do 2.9ghz with reasonable volt increase, so since they are not in PC's i own; settling for 2.8ghz with both on stock volts.

LCBKE - 2.85ghz max with 1.375v (stock 1.350)
LCB9E - 2.90ghz max with 1.400v (stock 1.350)

Would'nt worry too much coz i was getting 6-10c diff under load (not as bad when idle) between cores with them both - so seems most are like it i would guess.

 

[Sean_UK]

Yeah the 72w makes a huge diff, a fair bit more headroom at least temps wise.

 

[Sean_UK]

Sean, what was the highest you were able to get and at what volts? Was there any chance of for example having it at higher volts to get 3GHz booting into Windows etc?

Hi, yes one would boot at 3ghz, the LCB9E with 1.425 or 1.450 cant recall exactly, very unstable though.

 

[Sean_UK]

Mine is like that too at such volts and to get it 3GHz stable requires only 1.525v.

Ah i see, well since they were'nt my PC's then sticking close to stock volts was ideal. Still thats quite an increase imo, would'nt like to run say my 4800+ at such levels day in day out, thankfully 3ghz almost at stock volts.

 

[Sean_UK]

Yet another 4200+, managed 2.9Ghz with simple o/c on 1.375v Real good'n, shame its not mine to keep.
