Just click "All" button or pick the max amount of free memory your system has yourself for higher stress level. :)

I sold my 920 batch 3923A and got a 950 batch 3931A packed in November.
The bad thing is, my crappy R2E died on me !!
It lost one of the pins ! I hate LGA !!!

I had a batch 3903a which sucked. That chip would not run 20 LinX passes @ 4.2ghz on anything less than 1.365 Vcore and wouldn't post at anything over 201 bclock.

That lemon has been exchanged for a 3937A which seems to suck less, looks like it does 4.2ghz at around 1.329 Vcore; a bit better, still tweaking this one.

I have a 3922A415 batch and I need 1.34-1.35V for 4.2ghz HT off. I've found 3939Bxxx on eBay for ~$300 (inc international shipping). So what do you think guys should I gamble or just bite a bullet and stick with what I've got?

If you're on air then it is probably not worth bothering with.

So you don't think I can get the same clock speed with lower Vcore on 3939B?

Is it stable at that speed ?

Found one with the same batch#.

You probably will.
It is just unlikely you will gain more than 100MHz higher overclock due to the swapping. So just see for yourself if it's worth the $$$.

3931A is an OK batch. It has a high VID (1.28) but there is someone on the OC forums that is running 4.0GHz on a 3931A318 with stock vcore, and 4.2 is somethere is the range of 1.36.

I'm waiting to see what mine can do (3931A318). Can't go past 3.2GHz at the moment, as my PSU starts sucking too much power which overloads my UPS.

3941B092, 21x184@1.2v, vtt auto, memx8 c7, 5 passes linx on stock cooler. My classified EK block is finally here. So mid week i will install water loop to see how far this cpu can go.

I picked up a 920 batch# 3945A936 from micro center. I am still deciding on a board, I hope to be joining you guys soon. Any suggestion on a good over clocking board? Have been looking at the Giga UD7, the Asus P6TD Deluxe and the Classified, Classified is more than I would like to spend on any board, but if it is worth it I may try it.

the P6TSE is a cheap yet good board.

Classified or UD7 imo, see if you want better looks and digital PWMs of Classified for a few $ more. :yepp:

Thanks for the replies, the only thing holding me back from the ud7 are those ridiculously large heat sinks, I wont be water cooling the board, just the cpu. Will decide this week sometime and try to have it for the holiday weekend coming up.

Last question, I have 2 2x2gb kits of the DominatorGT-CMG4GX3M2A2000c8 from my 1156 rig ( got both kits for about the same price as a 3x2gb kit would have cost ), is there any reason I wont be able to use 3 of these stix with the 1366 platform?
