Corsair Dominator 2x2GB PC8500 DDR2

[Dr Dre]

Hello boys, can you say me which chip have this module
http://www.newegg.com/Product/Produc...82E16820145197
and can you advice me other memory between 140-190$?(4GB)

[zfactor]

those are powerchips and most people are getting really good results with them

[fireice2]

hmm how are things going at micron? Do they have something to compete with powerchips high density IC's?

BTW, can these chips handle sub 30 tRFC's? The way I see things these new 4GB kits usually run at higher tRFC's around 55.

[Don_Dan]

I think those Powerchip ICs need the high tRFCs >55 so they can really shine. Don't expect to run the tight subtimings you used with your D9 kit on a kit of those!

Exceleram EX2-8500 5-5-5-15 (2x1024MB) EX2-21066M2-SY *Micron*

Voltage: 2.2-2.3V Pins: 240

came across these sticks in a german shop, I am curious myself if some1 already test these

I have a similar question. What speed can be expected with <=42 tRFC?

G.Skil pc8500 do rather well on my old dfi board, but i suspect these chips to be better.

[Spyrus]

tRFC most likely is 2GB module suffer due to density though i have seen D9GSV with tRFC=30@500MHz+

Expect 35 up to 400MHz,42 up to 485 MHz, 43-50+ up to 540+MHz and for top line 50-60 up to 590 MHz

I cannot set manually more than 42 so I could live with 425/430mhz cas4.
Or just use the SPD and go with higher divider and freq.

Only bench will tell

Do they come with 8 layer PCB or 6?

6 layer.

Hey guys. Just got myself this kit and I'm wondering how you guys are getting such good results? Mine won't even run at their stock rated speed on 1066 5-5-5-15. I'm using an Asus P5E which is very similar to the Maximus Formula. I have tried ChaosMinionX's settings with no joy at all.



Anyone have any secret tips?

[dinos22]

hehe Jammer
why don't you try tightening the RAM a bit

i just got a retail kit in mail a couple of days ago
i'll do some testing on intel platform guys and put up a thread link when i start testing

[J@mmer]

hahaha HEY YULEH!

tightening? these are 2x2GB kits bro. They don't even run at stock speed and you want me to tighten? *faints*

OK well hurry up and get tweaking... Oh, you testing on x38?

yeah i know
i actually have the PC9136 kit here which is binned at 571MHz 5-5-5-x but i guess once i test it i will also test some 4-4-4-x; 4-5-4-x and 5-4-4-x timings to see where they are at................i realise that 2GB kits probably don't do all too well with tight timings but i'm sure you could tighten it somewhere if you are below stock speeds :

[J@mmer]

Yeh but they should run at their rated speeds! I'd rather looser latencies and more headroom anyway.

ATM I got them at 890 5-4-4-10 2.0V that's 1:1 (which I hate, prefer to run my ram faster than FSB always).

[dinos22]

1:1 is good
NB works less
better for long term and intel chipsets always perform well 1:1 anyways

[J@mmer]

Yes Chainy!

[dinos22]

[dinos22]

i've done some testing with my 4GB kit

600MHz 5-5-5-15 SuperPi and 3D benchmarks no worries

great RAM

Here is a link to the thread with full test report so far

I'm testing mine now for a 24/7 clock.

8GB at 561 MHz 5-5-5-15 tRD 6 so far so good. Left Memtest86+ running this morning for a long term test. Last night I got two errors so I bumped the volts a bit to compensate and before I left it was fine...

Man! Nice OC with 4 modules!

Thanks.

These are the only 2GB modules I've found so far that can hack it above 1100MHz for 24/7 on my rig. Hopefully I get home to a nice clean blue screen with no errors.

looks like there is some confusion here from at least a couple of members at XS

i am just ing with jammer. we are friends from i4memory and OCAU (FORUMS in Australia)

OF COURSE he should just RMA the RAM that doesn't run at rated timings rather than try tweaking

chainy is a mod in Intel section at OCAU and while a nice guy can have some captain obvious comments and hence why Zoltan here thanked me as chainy

STOP ing PMing me now OK
I love zoltan and he's my forum buddy yuleh so back off
zoltan have you though about changing that gaylord name of yours or what (THAT'S A JOKE FOR THE SLOW ONES THAT ARE ABOUT TO SEND ME ANOTHER PM )

see you at i4memory yuleh

[zlojack]

Success!

100&#37; pass on Memtest86+ for 10+ hours at 561 MHz PL6 on 8GB.

Now I need to start tweaking subtimings. Here's a benchmark:
