HT on also**

for me to get 4.4 ht on stable is becoming a pain. I mean I have 2 chips that will do 4.3 ht on fairly easy but will not do 4.4. There is got to be something I'm not doing right. This Classified board is not that easy to overclock. I need help!!!! lol

Someone heard about this batch ?

A friend just called to ask me which of the 2 D0's he found to buy...

He got the 3912A845 and the other one was a 3907A837....Hope he got the right piece...

When we test it , i'll come back with results...

Hi,

I have a D0 that I just put in that is running stock. It is running 12 GB of Corsair Dominator RAM at stock (1066mHz) speed. The CPU batch is 3910A313 that I got from the Tustin, CA Frys. I am using a Gigabyte EX58-UD5.

Anyone have experience with this batch? How well do you think it will do with 12 GB of RAM?

well I have no experience with D0's. but the more RAM you use the more your overclock is hurt. MOre stress on the memory controller. BUt if you use 12gb for daily use, then maximum overclock shouldn't be your priority.

No, I am not going for 4gHz or anything. I was hoping for anything over 1400mHz for the memory and 3gHz for the CPU. Is that doable with this stepping and 12GB of RAM?

I do not have time to tweak like crazy, I am just looking for a set and forget setting. Not looking to max out my stuff all all.

you could probably do about 3.4-3.6 GHz without touching voltages. So yeah very doable. :D

from 4.3 to 4.4 huge jump in vcore

How the temperature sensor on the core ? I have the same batch but some of the sensor is off scale. I saw some others with the same batch also have the same buggered sensors. It like a trade off ehh :eh: :rotf:

These Xeons are about the same, Mine can do 4200 WITH 1.23V linx/prime stable. try to take it to 4.3-4.4 and see how much vcore you need.

Thanks

This is one of the BEST 4.40Ghz run I have ever seen with HT enable and only needed 1.32 vcore, very very nice indeed! excellent load temperature as well. I assume this is water cooled?

He using air so it too hot to do any 100% load test at that frequency without proper ambient. Maybe his chip clock same as mine since it from the same batch and probably with the same buggered sensor too.:confused2:confused2:cheer2::cheer2:

I picked up a Xeon 3520 3850A823 this week from Buy.com so looks like I got the same batch and week as you hlonipha 3850A823. I'll have to get everything set up and test it out this weekend in my Classified 760. I need to try out my new beast of a power supply Enermax Galaxy EVO 1250W as well that I got earlier this week.

This is very nice indeed!!!! man congrats on an exellent chip:YIPPIE:

I will be buying another one, but looking to see who is selling the better batches out there.

ey mario with all these Xeons and i7 chips you be getting your hands on ;), you should start crunching. Or are you already? You got a great team to crunch for here dude :up:

Thanks. There only 4 batch for xeon 3520 out there for now and I saw most of the good one came from batch 3845A935 eventough it still a bit of mixed bag. No idea about 920. Seems like too many batch to scout for.:rofl:

Oh Sparda Your Xeon is amazing low Vcore!!! 4.4 @ 1.312V

where did you buy the xeon? I got mine from the egg. but since I need another one, I would like to buy it from a store that has the good batch.

Chicken: I'm not crunching rigt now. send me the info of the team and I will take a look at it.

check out this link. I would tell you to join my team, but XS has a great team and the guys here are great. I wouldn't do that to them. You can join team Xtreme Systems, theres a detailed how to in this below link. Lets keep this thread on topic though, if you got any other questions, PM me dude. OR you have my #, you can just give me a ring, i'll help ya out.

I'm outside of the states. I just mail & phone the shops in my country to confirm the batch. Looks like your neighbour knows every batch in Canada if you are interested.:p:

It low volt but the power draw nearly the same as my first chip that like vcore. I just confirm it by wattmeter when I swap the cpu.:yepp:
