I strongly suggest every user reports what the load Vcore was during testing to the best of his knowledge, that usually means CPU-Z, Everest etc while running the tests. Now I have never seen such an "overreporting" problem as on the DFI x58, so usually CPU-Z and Everest should provide accurate numbers.Quote:

Finally, on my DFI, the idle Vcore is actually a lot lower than load because EIST is working properly with manual Vcore as opposed to Asus and GB mobos, so the only choice that makes sense is load Vcore really.
DMM measured > readout ofc but not many people have the eopportunity to read the real voltages with a DMM, even around here.
I would love to do a DMM Readout, but do not know where on my mobo will show my my vcore =P its a Gigabyte EX58-UD3R

Pls update the first post if possible for people to know what template to use. Because in a few days you post is somewhere on a page and can't be find anymore. Otherwise PM the OP to pls update his first post.
I'm glad I mentioned the issue about different voltage reports. After reading some reactions it seems everybody had his or her own interpretation which leads to misunderstandings.

On the short term I will try to get 210 x 20 stable. Then I will make a choice between 212 x 19 or 210 x 20 OC. The advantage of 212 bclk is that my RAM runs at 1700Mhz (8-8-8-24-1T) but on the other side with 210 bclk my CPU runs faster and RAM could get tighter timings.
Will also try to get a 4Ghz setting stable with HT enabled. Tried that today for a bit but seems it needs a lot more vcore then (like 1.42v under load in CPU-z). Should I try to increase QPI/DRAM voltage when enabling HT?
Here's an update on my clock:

As I mentioned in another thread I'm having memory issues, but hopefully I'll be able to get them straightened out.
Just got my 920 3836A772 and so far it's a winner as far as I can tell. I've only put it together on the test bench, turned off the speedstep throttles etc, and put the Bclock at 200. It booted with everything else default. I have now been running memtest for the last few hours at BClock of 180 with everything default except for the ram voltage at 1.64.
Looks like a winner!
Can you people also post the Pack Date with your Batch # please...Thx!

No, that is correct. QPI is the same as bclock. It has replaced the FSB (as us i7 owners know).
bclock and QPI arent the same. bclock is the base system speed for the processor, QPI could be a 36 40 and 44x multi of the bclock...I think those are the choices in my BIOS at least.Quote:

Also, what about uncore speeds should we list that?
If we wanted to be most complete we should put bclock, QPI bus speed and uncore speed.
Hmmm EVGA techs have described it otherwise...I think you are talking about the QPI link speed...but I see where the confusion comes from. We will just call it bclock or bus speed from now on.
We can add anything we want. But the problem is everytime we add something previous entries become incomplete.
I think if we post the following data it is as complete as possible. This way everybody should be able te reproduce the provided settings on their own machine.

IMO if you have the qpi multi you dont need the frequency of the uncore but thats nit picking :) nice clocks btw
Thank you Bobbylite!!!! I think your right with the multi and all. But we have to take in account that there will be some n00bs as well who want to try OC'ing and maybe don't know that MP (QPI and Uncore) x bclk gives them the frequency.
Moreover my P6T-Deluxe doesn't use MP but I can only choose from determined frequencies which raise when raising the bclk. Therefore other people have the opporunity to select the same speed instantly.
Do you have a QPI frequency of 7400Mhz? Maybe I'm wrong but I think you mean 7400MT/s instead of Mhz.Quote:

You can have uncore multi of 12-16 not sure which ones my BIOS allow, but either way yeah. And you can have QPI multi of 36 44 46 I think are the options in my BIOS.
I'm sorry it was not clear but I refer to MultiPlier with the abbrevation MP, like you use multi.
Only on my Asus you can't litterly select a multi. You can only choose between a predefined selction of speeds which are ofcourse indirect multipliers. But they are not mentioned that way.
Could someone post the updated spreadsheet (as a spreadsheet, not image)? Thanks!
Dude, is your PC situated outside in Arctic conditions? Because, mine is and I can't touch your idle temps. My rig has nothing in the H20 loop but my CPU and my temps can't touch yours. My office is 64F right now and I live quite close to the Arctic Circle.Quote:

I bought the 920 3836A772 which is the exact same chip as Cardnut99668 (3836a772) and he gets 211x19 @1.376 with temps at 85,83...
For the life of me, I can't go over 205 and the best I can do is Linpack stable but not prime95 stable (go figure..) at 20x200 and 1.49V. I can only get this stable at around 3.8 GHz and lots of volts (I'm on water so temps are much lower than Cardnut's)
So, I have given up with this 920. I ended up buying a 940. The extra multipliers (22) give you an additional 400 MHz to play with around 200 making it much easier to overclock.
I now have full stability at 4.1 GHz in one try. It will boot at 4.4 (22x200) GHz but not into windows. This is stock auto voltage. Maybe I'll see if I can get this to work!
It's also 3836A like the other two. But again, it won't go higher than 205. Perhaps there is some motherboard chipset influence in some cases. The eVGA Classified should let us know about this. First benches bring the Bclk up to 233.
So in the end it's back to square one? If I know that people got 3838B079/080 or 3837B079/080 to run decent clocks with around 1.35-1.4 it's still not safe to say that I'll reach that with the same batch. Or is it just a trend that B batches are better?
I will update and add the other features tonight.
seems like the Gigabytes and ASUS need less voltage than DFI one. Still havn't seen 4200 ghz with HT and Turbo on with an UT DFI...
With my 3837B395 I'm not able to get 4000 Mhz stable with 1,46V + and low DDR3 speed. System crashes with 191x21 or 200x200 =(
Perhaps i shout get a Gigabyte additionally to check out the differences.
B's tend to be better HT clockers overall, and less voltage :up: but some will clock well others will be crap like all chipsQuote:

Not 4200 but close. HT on. No need for turbo with 220bclk.Quote:

PD-Still testing if i can low vcore, this thing burns
We were at MC last Sunday and my Brother bought one of this same batch but he hasn't the time to let me assemble his rig yet (he is complete newb to PC assembly so I will have to put it together for him). We were there because of the 20% saving MC is having until 3/1 and I urged him to buy new stuffs as his current PC is getting pretty old and slow. He bought the MSI X58 Platinum SLI along with an i7 920, a 9600GT, Kingston Value PC3-10600 (DDR3-1333) and few other stuffs. I will be putting it together for him this coming Saturday so we'll see how OCable this batch can be.Quote:

Looks like the 3836B isn't the champ I thought it would be, but it's capable enough for me. These numbers aren't final, I need to do some voltage tweaking as I think I can lower some of them, tweak my RAM timings, bump up the uncore, and push for 4.2 GHz when I can find the time. The idle temps seem a bit high for water cooling, might have a bad mount. More to come.

all these results really need to be put into some kind of database for easier browsing
read through 500 posts? no thanks!
unfortunately the database at overclockers.com is down for redesign

Also an extra setup for applications without support for HT.
@4.2GHZ(200x21) HT:off, 1.37v

I have been using the 4GHZ + HT for 24/7 for a while now, and this is going to be my primely set up, but I have switched to 4.2GHZ HT:off a few times too.
The have 3841A321 at a shop here. I'm tempted to pick one up and see what it does but I don't see that many 3841A results in the spreadsheet, though there are a few in the thread.
Are there any negative results from that batch?
Either that, or maybe I'll wait for the D0 stepping to hit.
And x58 B3. You'll have to wait for a little over a monthQuote:

Those are my daily 24/7 settings. Batch #: 3841A529
I am now running the RAM at 8-8-8-20-1T though. That screenshot has it at 8-8-8-25-1T. The chip is 4.1-4.2 benchable with 1.44v, but 4GHz is the sweet spot for 2000MHz RAM.
dont have pics but have 3839A604 and did 4.3 @ 1.45 ht on and turbo on.
My temps were all around 90C
90C on water?Quote:

One instance of the newest P95 should max out all eight threads with HT enabled. I run the Blend test to check the stability of my system as a whole. Intel Burntest is far better for determining the stability of your CPU. It will usually detect an error FAR faster than Prime and will increase your temps well above what P95 is capable of.Quote:

I'm not at home now so I don't have the time to dig it up. Remember, Google is your friend. :DQuote:

anyone has a 920 3838B038 batch?
Not me, but I did see 10x 3838B938's on a shelf the other day and was tempted to try one:shakes:Quote:

Sorry, his stuffs are still in bags...won't get to them until sometime Saturday. Will have some result soon afterward. But consider his board is an MSI X58 Platinum SLI, not sure how it will OC vs. R2E or other brands. :confused:Quote:

I'll report back on my findings here.
