>> Micron DDR3 / Corsair @ DDR3-1960 CL7-6-5 >> very fast SPi32M runs, 13k Everest <<

[bachus_anonym]

Hey,

After some consideration, I decided that since we have already seen and proved that Micron 1Gbit parts will do DDR3-2000+ at CL10 or CL9 with better modules, it was time for some fast & tight action. Let me then introduce what DDR3 is capable of in terms of high frequencies at tight latencies, with some good help of good 'ol voltage

What I have here is a 2x1GB kit of DDR3 Micron-based modules, that happens to be coming from Corsair - yeah, no surprise here this time, right? For those unaware, I work in Corsair's lab, and deal with all kinds of memory/motherboard related testing, validations, overclocking, etc.

Anyway, fasten your seatbelts because 13k Everest Bandwith is coming real fast. How about we warm up with 2000+ at "slack" timings, and easier 4GHz CPU, shall we? Something worth noting is, that all overclocking was done solely from BIOS and FELIX's latest Memset was used only for those interested what memory settings/timings were used,

- Asus P5K3 Deluxe, 0504 BIOS
- Core 2 Duo E6850, 1333FSB
- Corsair DDR3 modules
- Corsair HX520 PSU
- eVGA 8800GTS


DDR3-2040 8-8-8-18 @ 2.30v, E6850 @ 510x8=4080MHz --- CPU-Z Valid @ 8-8-8 --- CPU-Z Valid @ 8-7-7

Now, let's do that again, but below both 4GHz on CPU and 2GHz on memory

DDR3-1960 7-6-5-15 @ 2.30v, E6850 @ 490x8=3920MHz

Next up, rather fast 32M run, isn't it?

Those would make for good and I think first DDR3 entries for coop's "32m Low Clock Challenge" contest

... one for 11:xx category - I was so close to do it below 3.90GHz, but memory would just stop at above DDR3-1940. So I had to step down a bit. Still, a very fast run, right?

DDR3-1660 7-6-5-15 @ 2.00v, E6850 @ 498x8=3884MHz

... and one for 12:xx as well. This would make the best result so far, If DDR3 results are to be accepted in that contest.

DDR3-1700 7-6-5-15 @ 2.00v, E6850 @ 510x7=3570MHz

While I was at it, I run a quick ORTHOS test at above settings as well.

DDR3-1703 7-6-5-15 @ 2.00v, E6850 @ 511x7=3577MHz

So, there you have it guys! There is some even better stuff coming along on DDR3 front as you can see. Let me just point out, that this is in no way presentation of what all Micron DDR3 based modules will do, but just a sample of possibilities out there, for those if you curious to see what happens when more than default 1.5v is applied. But let me say, that 2.3v that I was pushing through these modules DOES NOT seem safe for extended periods of time.

Thanks for clicking through and see you next time If you have any questions or requests, let me know and I will try come up with something...

Holy crap! @
DDR3-1940 7-6-5-15 @ 2.30v, E6850 @ 485x8=3880MHz

& 11M 58s!!
I wish i had a ddr3 board to play with.

[over@locker886]

Great tests

Thanks for sharing

[funkflix]

DDR3-1700 7-6-5-15 @ 2.00v, E6850 @ 510x7=3570MHz

That is really fast! Nice results.

[K404]

The important question I think needs to be asked is...

What voltages are currently considered extreme/damaging etc for DDR3, or is it still too early to tell?

Have the Corsair labs tested module voltages until they fry?

The MHz, timings and Spi times are impressive

[kemo]

Nice work BA , really impressive , but i have a questions ,,, Is that is a handpicked or random kit ? those ICs are as hot as D9s or run cooler ?

Is that an answer for my question or you are talking about different Micron ICs

[toddm27]

very impressive, makes me want to dump my ddr2, and jump on these

[DeDaL]

I need this ))))))

Thanks.

[rick_fx]

Under 13minutes Spi 32M at 3570Mhz. Wow!

[bachus_anonym]

Thanks for good words, guys!

The voltage I applied in parts of this test (2.3v) does NOT seem safe for prolonged use, and should be definetely reserved only for those that are are aware of a danger that could arise from 50&#37; voltage increase from default 1.50v. On the other hand, I have not seen Micron DDR3 being damaged with up to 2.0-2.1v. But again, early to say, I think. Also, some ICs will benefit from anything higher than 1.8v and some won't.

Nice work BA , really impressive , but i have a questions ,,, Is that is a handpicked or random kit ? those ICs are as hot as D9s or run cooler?

Not really handpicked, but consider it a result that may or may not be representative of all Micron DDR3 based modules. That's all I can say at the moment. Plus, it's to early to say as these Micron chips (if you look it up at Micron website) are still technically ES. The above results are intended as an early pre-preview, and be considered as such.

[SoF]

that's what I've waited for since release of DDR3 - nice ddr3 timings on sweet mhz - thanks for the detailed results

[Viss]

Insane 32M for the clocks and glad to see tests from you again

[andre X_X]

OMG 3570mhz sub13 were just amazing..... great memory, great tweaks, great ocer.... very cool...

[dinos22]

hey BA i was waiting for this thread

crazy ICs

so much for someone saying the other day DDR3 die instantly at 2.3v lol

[metro.cl]

lol i might have a picture of you Bachus, i took some pics of corsair tech lab :P

[Redbeard]

lol i might have a picture of you Bachus, i took some pics of corsair tech lab :P

He's the guy with the shaved head whose lab table has like $50,000 in memory on it at any given moment!

[Gautam]

Very very fast results bachus...but I've got a feeling that DDR2 properly tweaked with P35 can match those.

Anyways its about time someone made the new tech look...new.

[eva2000]

Yeah DDR2 properly tweaked on P35 could do it or get close

but very fast stuff Bachus especially 10k everest copy bandwidth.. that's what stuck out at me.. 13k read too

Obviously higher cpu FSB helps with such bandwidth too

[erwinz]

very nice BA


DDR3 is looking good.. I hope there are more memory players here unlike DDR2 that is mostly micron..

where is samsung or hynix??

looking forward for more of your test..

btw.. BA.. can you test using 1066 conroe's any E6600 retail there in your lab..

[metro.cl]

He's the guy with the shaved head whose lab table has like $50,000 in memory on it at any given moment!

Hey havent seen you here nice to know corsair is here

I'll have to look at the picture to see if Bachus is in there

p.d. i found him (had to cut the picture couse of nda:


and you also had lots of toys to play:

[bachus_anonym]

lol i might have a picture of you Bachus, i took some pics of corsair tech lab :P

I think I remember you were on a tour with a bunch of other guys from South-America.

He's the guy with the shaved head whose lab table has like $50,000 in memory on it at any given moment!

That's probably correct...

I'll have to look at the picture to see if Bachus is in there. p.d. i found him (had to cut the picture couse of nda:

Yup, that's me

Very very fast results bachus...but I've got a feeling that DDR2 properly tweaked with P35 can match those. Anyways its about time someone made the new tech look...new.

I might be wrong, but out of those three 32M runs above, 12:02 @ 3.88GHz might be the hardest to match with DDR2, even on MCH register tweaked up P35. Time will tell, of course.

Yeah DDR2 properly tweaked on P35 could do it or get close, but very fast stuff Bachus especially 10k everest copy bandwidth.. that's what stuck out at me.. 13k read too Obviously higher cpu FSB helps with such bandwidth too

Thanks George! Yeah, 13k Read and 10k Copy should be out of reach on curent C2D DDR2 platform, at this CPU speed that is (3920Mhz). I was messing with P5KD, and Striker Extreme, and did not see 12k+ happenning...

I'm a bit busy at work right now, but I will make another shot at 11:xx below 3900MHz. Those 3s were driving me crazy, and still could not loose it... Only tweaks I used at that time was maxmem=600 (which seems to be a bit overrated, from what I have seen during that test) and copywaza (which shaved about 5-7s of each of those 32M runs, compared to "untweaked".

Thanks again

i'll see what i can do.. only 1:1 on DDR2 so have yet to play with mem divider

[afireinside]

Good stuff B_A DDR3 looks good for once! Hopefully prices will come down soon.

Those 32m times are damn fast. That 3880mhz run is only 1 second slower than my 4.45ghz run on p5b Ah the raw power of 1333 strap + no 32m tweak knowledge.

On Asus ftpserver there's a 0501 bios for P5K3 Deluxe, but no 0504...

Huh Michal play again and play strong

Nice to see You back to posting Yours test

btw : what vcore for 3.8-4GHz cpu clocks ?


Thanks and regards
