anyone got idea's about my prob? :(
i dont wanna have to go through the process of returning and rebuying
@Duonger:
What's the thing with 2 different color Brainpowers (green/black)? Do those have different chips? Which is newer batch?
I just got the dc kit and they came on green pcb, They are running at 255 (2,2,2,5) with 3.5v. I'm happy with them and the price :)
Update. Just burned in first stick at 255 3.35v with memtest, ran 12hrs with zero errors. Just by testing 2nd is definitely the weaker of the two. Haven't ran memtest yet but won't complete superPi at 2m at same settings and voltage. Finally passed at 245 3.3v. This stick will need lots of catching up. Notice as well these seem to run hotter even with HS removed compared to my TwinMos SP utt ch5.
Overall can't complain but not quite as good as my TwinMos, not yet atleast.
Duonger answered this on the OCforums at the link below... I have copied and pasted his reply for the convenience of those reading this thread :).Quote:

No it shouldnt matter. They are all Brainpower PCB but just with a different soldermask color. When we mde this deal with Frys they just wanted the parts in the stores asap so I built them up with the boards I had left. Sorry for any confusion but no, the boards do not matter. They are all 815BPB.

Hmmmm, Is this something new? From what I have read, aren't they all suppose to be on BP PCB? :stick:Quote:

I hope Muskin did not pull a switch on us. :brick:
no not all of them, some of them are the old school actual bh-5 like what was in the original 3500 black level II same pcb and all.
These look awesome... and they are new BH5 too.. Man I have to get some of these, what a great price too.
Sheit! Is this good or bad?Quote:

I guess we can't complain because of the price we are paying, and I haven't even tried my sticks out yet.

I received my DC kit I ordered yesterday and have them fired up. So far... I am at 230HTT with only 3V. My VX would do 220 at the same voltage. I have not bumped the voltage much as I am going to burn in at 3V, 3.2, 3.4, etc. I will keep you posted.

UTT- that is the term we in the memory industry call for untested raw chips directly from the build houses. They have not been screened or tested for any speed.. ie ddr266, ddr333, ddr400.
The job of the memory manufacturer is to bin and test and qualify these utt for the parts they need. This testing is usually expensive and time consuming and the yeild rate varies.
AS FOR THE SO CALL WINBOND UTT-------
Winbond makes 2 different versions. There is a BH and CH quality. there is NO BH-5 or CH-5 anymore. Winbond does not mark any of the chips anymore. Most of the new UTT are built by Infineon for Winbond.
So based on the 2 dies, the memory guys like US or Twinmos or OCZ buys whichever one they need and test them to get what grade or yeild they need. Once they have that then they allocated to a specific part or product that you the consumer see as the final product. So depending on the testing and binnnig as u call it, there are various yeild rates for certain speed and latency.
Thus, not all parts are the same. You can have a BH built module but it only runs at xzy speed with xyz latency BUT with a lot of testing and binning, you can have the same BH die part that runs at a xyz+ speed and lower latency. The cost and time is in the testing and retesting and testing thus like the old saying ... *you get what you pay for* but there are some lucky few that will get more than what they pay for.

Well i hope this helps...

Duonger went on to say in a subsequent post that there were about 100 units built with original bh-5 (like Shroomalistic got), and the rest with the new bh die. The new stuff uses the BP PCB, but because of time contraints, they used whatever stock they had on hand, which is why some are black and some are green, but otherwise they are the same.Quote:

It may be fine with add't voltage, but just won't hit 2-2-2-x at 2.6v. Again, that is just my personal opinion and is not supportable in any way, other than the following logic. If they had bh-5 chips capable of being used in Level 2 modules, why would they not have used them when the product was in such high demand and commanding a premium price? Or why not save them for RMA purposes?
Why use them (left over original bh-5) now in essentially what is value priced ram? The only logical conclusion that I can draw is that they simply do not meet Level 2 specs. They are probably even below the "Promo Build" specs that Mushkin built and released a couple of times in 2004 (early 2004 and then again in August).
the left over bh-5 was not from mushkin but from winbond, mushkin just put them on there black level pcb.
Just want to make sure that I understand your statement.
Are you saying that Mushkin just recently got a shipment of old bh-5, as well as new bh die from Winbond and are using this new shipment to produce the current batch of Mushkin Blue? I haven't seen that stated, so I must have missed or misread Duonger's posts where he stated that they just got this stuff. Can you point me to it so that I can bookmark it for future reference?
As I stated in my previous post, my take on things was not based on anything but my own conjectures, so if there is information either confirming or debunking my "theory", I am most interested in seeing it.
I do remember reading that they produced about 100 units from old bh-5, but not that they just received a new shipment of old/original label bh-5.
I have to admit that it seems strange to me that Winbond would have a stock of bh-5 chips just sitting around since late 2003 while in the meantime the whole ram world was going crazy trying to get stock. I, of course, am not in the ram business so how they do things is beyond me.
Ok, updated results for my Mushkin Blue with 2-2-2-5 timings on my AI7, single sticks. Test 5 was looped 20 times for initial testing.
Green BP815 PCB stick #1:
2.7v = 205
2.8v = 215
2.9v = 220
3.0v = 225
3.1v = 230
3.2v = doesn't like it even with fan cooling
Green BP815 PCB stick #2:
2.7v = 205
2.8v = 215
2.9v = 220
3.0v = 225
3.1v = 230
3.2v = doesn't like it even with fan cooling
As you can see, each stick on the BP 815 pcb ran about the same, I noticed the second stick doing slighly better, but very close performance. I'll start testing the sticks on black pcb today and hopefully get to start doing dual channel tests later this afternoon.

Shroomy,
Thanks for the link...every since I got that "warm welcome" over there I don't tend to go there very often. Based on what he (Duonger) said, it appears that these new Mushkin Blue use both, old bh-5 which Mushkin had saved for RMA purposes and new bh die. Here is his post copied below. He is responding to the question of whether these chips were held over stuff that Mushkin had kept for RMA.
*********************
Yes and No.. Some were for RMA but when I got our chips this past month, Winbond sent us some of their old BH stock so I used those as well.
Its cool. We offer a lifetime warranty. The parts that come back as RMA we cant sale as new.
Duonger
*******************
End of quote.
Notice he said he used "those" (new shipment) as well (as old RMA stock).
I am very surprised to hear that Winbond had old stock left. Must have been sitting in the Janitor's closet or something. :)
Again, thanks for that link. It helps with the overall picture...which is that there is old RMA stock, new shipment of old original bh-5 and new bh die being used in the latest Mushkin Blue dual-packs...somewhat confusing, but the good news is that it should all be pretty good ram.
Does your AI7 track VTT? Result still looks good none the less.Quote:

In such case, give it some time to burn in... I think the heatspreader attachment is not quite as good as some others as I've noticed some sticks not operating at 3.5v initially now doing fine 3.5v. I have feeling burning in process on these new sticks are more of issue of heatspreader conforming to chip. I WILL take these out later for maximum performance when Venice comes around (hopefully letting me utilize more than 230-240ish 2.2.2.6 out of this stick by having higher CPU overclocking each stcks now do well into 260 2.2.2.6 zone :P)Quote:

I'm pretty sure the heatspreaders are making good contact because they get really warm meaning they are conducting heat from the chips well. My old Mushkin Promo Build BH-5 had no heatspreaders and they ran cool to the touch up to 3v on my NF7-S. I really do prefer to not have heatspreaders installed, but I'm not going to void the warranty just yet :)
They finally went out of stock... game over :(! Frankly, I didn't expect they'd last this long :p: !
