My results with patriot BE-6

Already posted this on an Australian site but I thought I’d move it here as well to get some international feedback. I purchased a 2 gig set of patriot ram from a local aussie dealer when it arrived, and as stated in another thread it turned out to be BE-6, as opposed to the BE-5 or CE-6 that has been encountered by American’s who bought this.

I can’t find anything on BE-6 chips, so there’s little for me to really compare this with. At this stage I’m only running a 3200+ Winchester on stock air in an abit av8 mobo. My NF4 SLI-D and 3800+ X2 will be coming soon. I’m hoping the extra voltage, better motherboard (the av8 is a via chipset =/) and better memory controller will help improve these results.

Things I’ve found so far:

1) I don’t think my motherboard likes 250 HTT or more. Even with the multipler down to 8X and vdimm increased, it won’t even post windows at 250 2.5-3-3-8, despite the fact that at 245 with the same timings it is SP 32M stable. Surely 5mhz wouldn’t have such a big impact, making it go from rock solid to not even postable? I was expecting a gradual decline in performance. Might be explained by the fact that it is a via chipset.

2) Tref value makes a HUGE difference. By default I believe it was on 200mhz/7.8us and I couldn’t get past loop 6 of SP 32M. After tweaking it for a bit, I landed on 200mhz/3.9us, and 200mhz/1.95us, both of which did a full 32M run with the same HTT/timings. From loop 6 to a full run is a massive difference. Memory bandwidtch in Sandra between 200/3.9 and 200/7.8 is almost nothing (50-100 pts).

3) These chips don’t like cas 3. They are more stable at cas 2.5 than 3.

And without further ado, heres a screeny. I did this last night, 240 at 2.5-3-3-8 SP 32M stable. This morning I ran it at 245 same timings, but I was running out the door so the screeny isn’t online, its stuck at home. Sorry the screeny is slightly cut off but the other place I uploaded it has a size limit, and I didn't have irfenview at the time to change the quality (recent format).

I’ve been burning at 240 2.5-3-3-8 with 2.7volts all yesterday, this morning I set it to burn with the same at 245. My :banana::banana::banana::banana:ty mobo goes up to 2.8v, but I don’t think these chips like much voltage, because I don’t see a sizeable improvement.

Considering most ballistix users get 270-280, and these cost half as much for 20-35mhz less (but at slightly better timings) they’re a bargain. I want to hit 250 with my timings and I’ll be happy, 260 and I’d be ecstatic. I have yet to tweak other settings like async.

Enjoy.

260 is quite impossible i reckon..

this is what i am at atm..

they like vdimm between 2.7 and 2.8 and not higher for my sticks

and yea they do better on CAS2.5.. try tightening some of the timings..

for mine 3120 and 2048 are the best.. the rest fails 32M instantly or fails a few loops into 32M

try playing around with drive strengths and data strengths as well.. mine does very well with 7 and 2

I don't understand why 5mhz would make the a 32M SP stable system not even boot windows though. It should be a gradual decline. Like i'd gradually get more errors and be able to run less and less SP's till eventually it wouldn't boot.

245 is perfect, 250 won't even boot and has trouble posting. Theres gotta be something else wrong in there.

yea that is what i experienced as well..

still trying to find something on it..

i'm on bios 618-3 now.. might try some -2 on yellow slots.. who knows it might work well..

u can try running memtest test8 @ 250.. it'll pass but test 5 will give u 40k errors LOL (well that's when i stopped it and clocked it down)

Are your sticks patriot sticks? Your signature says corsair =)

And if they are patriot, what chips? BE-5? It seems australian shops got BE-6 sticks, but all american shops have BE-5. I cannot find any other sticks that use BE-6 chips, which is annoying.

they are BE-6 and Patriot 3200LLK 2GB kit :toast:

Ah ok, good.

At least there is one other person with the same sticks so we can compare =)

Where did you get them?

the same place u got them from :)

Ahhh =)

Ok good, i'll keep updating as I do more stuff. At work now though. If anyone has any ideas on how to fix the 250 problem, let us know.

Another i4'er here with 2GB Patriot :)
I'm still testing different speeds/timings. :)

Latest results. Since I've yet to go above 245mhz im tightening timings instead. 245mhz 2.5-3-2-6 SP 32M stable.

thats all? push that babe !! ahahahah

lol they won't do 250 at all pal

ahhhh lol..

Yea, theres something very strange going on. It just refuses to do 250 at all, despite 245 being rock solid.

I'm going to try loosening the timings a huge ammount and see if it still doesn't work.

Ok even with 2.5-5-5-10 timings and upped from 2.7 to 2.8 volts, the ram crashes as soon as i set it to 250mhz. Is it possible for them to lock it at a certain level or something? I seriously can't understand how 5mhz can change stability so drastically.

lol trust me it can

can anyone tell me what chips that are exactly ?

infineon or something else ?

Infineon BE-6 are on these chips, but they're the ones we got in australia, american buyers have got BE-5 and one got CE-6. All infineon.

these sticks are exactly what a friend is searching .. needs 2x1024 @245 ..

and wtf are these BE6 so much better than the BE5 and CE6 ? (do CE5 exist ?)

by the way .. it shouldnt be such a big problem to get these chips in germany ...

CE-5 does exist.. and theoritically it should be better than CE-6..

thanks man :toast: .. taking a tour through some local stores ... having a look for these chips :-)

what are be5 and ce6 doing @relaxed timings ?

check the 2GB database on the top.. you should see some BE-5 results..

at the moment only Gaspar got CE-6.. and he's doing 280 3-3-3-8

could be winbond-infineon chips.. anyone tested how they react so some volts at 2-2-2-x timings?

it doesn't like voltage.. anything above 2.9 gave me tons of errors

I'm reasonably happy with the results anyway. I'm going to keep pushing, but if you look at the ballistix, people are averaging about 270-280 at 3-3-3-8. This ram is doing 245 at 2.5-3-2-6, so thats 25-35mhz slower, but with better timings, so its probably what, 10-15 mhz slower? And it costs almost half as much.

I just plucked in my 2x 1GB Patriot PC3200LLK 2-3-2-5 kit into my rig, seems for first 12hrs i've played with this ram i've gotten it to the about same limit as AndrewK at i4memory.com ~245mhz 2.5-3-2-5 at 2.69v vdimm seemed disappointing compared to crucial ballistixs at first but then the memtest bandwidth is very nice for san diego core cpu due to tighter timings since san diego cpus clock for clock show 350-450MB/s less bandwidth in memtest than venice/winchester/clawhammer cpus

250mhz is no go right now but will see heh... Gaspar's ram is a rare gem :D

not bad

There's a BGA-version of both BE- and CE- in production. I wonder where do they go?
Part number's are identical except for the letter between die revision (B/C) and speed grade (-5/-6). The BGA chips end in BF- and CF-.

Theoretically BGAs should be a bit better than TSOPs.

Anyone seen Infineon DDR1-BGA modules floating around anywhere?

Im also running these modules but my clawhammers mem controller craps out at 234X11 anything more than 2.5 volts on the chips causes many errors. Nice gains in sandra at tref 2048 and 3684 tho.

probably DFI NF3 250Gb limiting you

i was under the impression pretty much no 2gb kit could do 2-2-2-X because of the strain on the memcontroller?

well it ain't 2-2-2- it's 2.5-3-2-5 :)

High memory density and low timings do not exclude each other.
The problem is that atm 512MBit chips simply can't do 2-2-2-x at speeds high enough. Remember that not all 256MBit chip do 2-2-2-x, even at stock.

A memory controller doesn't really "care" wheather they are 2x1GB or 2x512MB dimms that are slapped to the dimm slots. All it cares is the amount of ranks a dimm has. "All" double sided 1GB ddr-dimms are 2 ranked just like all double sided 512MB ddr-dimms are 2 ranked. That's why you can even run 4x512MB - for example Mushkin Redline - at DDR500 2-2-2-x 2T.

After all, bigger memory space is only more options for the controller to place a single bit. ;)

Im still testing my kit for the max..

So far I have whats in my sig 10 hours prime stable..

Have any of you tried a 4x cpu multi? Mine do 280@2.7 volts2.5-3-3-6 rest on auto. Using a higher multi is when things get tricky :p:

Some nice results guys. I am considering the patriot for my dothan build. The lowest price and cl 2.5 performance. I wonder what they would do on Intel?

I got some patriot 3200llk 2gig kits yesterday, its got be-6 ic's

so far im stable at 500mhz but like andrew said, antmore and its a no go.

http://home.comcast.net/~thinkblaze/2gig_500_stable.jpg

Could be CE-6 you've got there (if you haven't already popped the hood to peek)....anyway, those are some good results for not-uber expensive 2GB kits, good job :D

I check under the heat spreader already, there deffinitly be-6's

VERY good results for later BE-6 then :toast:

weid thing is they top out at 250, any higher and its bsod. I just primed for 6 hours with no errors but at 251 its bsod. its got to be a certain timing stopping it.

after a little burn in I was able to get a little more out of them

Babyelf bro....

i came across HYPERX PC3200AK2 which uses the CE-5 chips....i'm kinda dissapointed which is want was CH or BH series chips....

Now that i found this thread its like being lost at sea and when it just seems to fade away...a mountain from an island nearby shows its peak...

could someone post some benches for 2.5-3-2-x vs. 3-3-3-x, cos i'd hardly expect any differences. or did i mis something on this topic?
(i'd test it myself but i'm still waiting for the psu :( )
