MSI Big Bang XPower - X58 mothetboard - w/ official support

[uncle fester]

is the ocp and pwm mod required for retail release boards ???

is the ocp and pwm mod required for retail release boards ???

CPU OCP is supposed to be set to 300 amps on the retail boards. Not sure on the PWM mod - I have not seen it.

[Raja@ASUS]

Is this a problem all across the line or just board per board?

No idea, only MSI can answer what they think the cause is. Unless timing X is pointing at bit Y for some reason (MSI reckon they have fixed all the sub-timing issues) there is no software explanation. My boards don't like anything past 16X Uncore with Hyper at CAS 8~9 over DDR3 1900. I see you guys aren't having the same problem and I've seen the subs you are using, so I don't know what to think at this point, I can only go by what I am seeing here. Outside those settings there is nothing else in software that should cause this to manifest. I've used two differnt CPUs as well and it still happens.

Forget stress testing, 32m single thread while benching is almost instant lock and reset (most I get is the first loop and sometimes into the second) even with some very loose subs. 3000~3200MHz Uncore on air/water for stress testing is just about doable with DDR3-2000, but anything higher and the boards I have fall over (BSOD, lockup) fast. Same parts on three other boards do a lot better with lower overall voltage and tighter timings.

ocp i think is set @ 200A.... mod..definitely need for ln2, one cpu we tested could pull 700w from the wall...

pwm freq is set to 250khz...mod raises it to 600khz...i like higher freq.

i just wonder how many revisions they've made... team mate bought retail recently...bios settings didnt fix memory issues..

They told me 300 amps on the CPU OCP. It is possible they have revised under the hood a few times.. Trouble is there are boards like this out in the wild, so I'm going to call it based upon what I am seeing here.

Thanks for the heads up, seems that there's indeed something wrong.

This is probably the same issue what the guys over at the hwbot thread are talking about.

I wonder about this retail board... the ocp mod resistance was set to 82.5k by default just like the other retail board. I am wondering if there was an update to the new board I have..
The first board came with an early bios that was anightmare.. don't remember the version... this board came with 1.2 by default.. so it must be a newer revision..

maybe Ill return the resistance to stock to see if that helps at all. If ocp has been changed to 300amps instead of the 200amps that I was told.. could help.

I have tried pretty much everthing... Subtimings. Different Multipliers, uncore, blcks.. 5.4ghz is the limit on this board.. I am going to try high vdimm to see if it helps.. I am pretty doubtful though... I also have a new bios to try.. but we will see.

Well some of what you are seeing might be OCP related on your board there.

The 32m issues people are experiencing are not necessarily born from 200 amp OCP limitations to VCC. Single 32m should pass a lot higher than what I am seeing here. To me the problem seems to be related to VTT and VDIMM. Assuming the timings are pointing at right locations, a requirement for high VTT on a board usually points at a fundamental signaling issue.

[steponz]

Very Interesting... I know when I lowered the resistance on the mod.. It worked with wprime for 2 runs... then it would fail everytime after... Which caught me by surprise...
I went away from the machine for a while.. cause I was getting really irritated with the new board.. so my cascade warmed up.. I wonder if the board getting cool has something to do with it....

[Dahaka]

No way to get PI's 2000MHZ cas6 stable, in fact my oldies OCZ Platinum can't set to default timings.

Everest go really bad with both kits, G.Skill and OCZ.

Same issues here man with GTX2 modules.

[Raja@ASUS]

My best advice would be for you guys to RMA your boards and take a chance on another or replace them with something else. Anyone on Bloomfield that has an enthusiast level board from the first generation of products should hang on to it, no point in upgrading to any of these second gen boards for Bloomfield in my opinion (SATA 6G and USB3 aren't killer features just yet).

wow, that is sad, i had such high hopes for the BB xpower, plus my R3E has yet to really impress me... Guess that is the bane of the cutting edge,

should have jumped on some of those cheap classies that were for sale when the new boards came out..

[Dahaka]

but face to face with RII3, Classi and UD7 the BB Xpower is more cheapest than other models. If others revisions doesn't have this problem with OCP and alpha timmings will be a good choice or maybe a good BIOS.

i'm still waitin to see if this board will be good with a new rev

the rexIII dont impress me neither my old rexII woops it good

[steponz]

Looks like I have a newer rev board... Ver 1.1 is supposed to have 360amp OCP. Going to remove my mod and see what it can do. Have to wait til tomorrow though.

Raju.. What version boards do you have?

[Raja@ASUS]

An early 1.0 ES and a retail 1.0 (input inductors and OCP modded direct from MSI, so effectively a 1.1). They are both poor at clocking memory.

[Raja@ASUS]

Just had confirmation from MSI HW - all retail are supposed to be 1.1 Steponz - the main changes being the input chokes and the OCP. Memory issues withstanding.

[Johnny87au]

Keep the updates coming guys.
I really want to get a new x58 board and this one looks good - just wanted to give a non-Asus board a chance for a change...

Ud9?

[steponz]

Just to expand a little bit further for others thinking of purchasing this board.. its are a real POS.. I would look at a classified or Rampage 3... I went through 2 for the contests.. the first one was really bad.. and finally died... memory issues.... So then I bought another board to get onto the Lords contest... and guess what... way worse than the first... I took the same CPU that would not go past 5.4 ghz HT on... put it in my classy and only did a little testings and was able to get 5.8 to 5.9 wprime32m stable... the MSI board.. would fail constantly with memory issues... do yourselves a favor and look else where..

Instead of RMa'ing my boards.. I will be torching them for all the grief they have given me... I am actually glad to stop benching them.... Will never buy an MSI product again based upon this.. No RMA for me.. I don't want another board....

my gut told me the xpower was gonna be a POS
i got a rexIII its good but bios is only geared for subzero and gulftown

funny this is an official support thread but no support lol

i was expecting more reading stuff but not...

+2 / +3 / +4 / + etc etc lol.

Maybe the staff need more time to develope this MB...

I am the one responsible for the "official" part so I take responsibility for the issue and bear full weight of that

I am sorry, I have slacked a fair bit, life for me has taken a few twists and turns for a while. Been a sad depressing time losing a family member too young, tend to let stuff affect me too much that it interferes with my duties.

I will be trying to get these issues condensed and summarized for hopeful resolution...

If you can do me a favor and PM me with you issues and be as detailed as possible to describe the issue, all troubleshooting attempts w/ outcome I will add that to my documentation
