Micron D9 GMH\GKX\JKH etc club

[Elektrosadist]

i just binned my rams with Memtest86+ cause i wanted to handpick a pair. Turns out my ram performs rather poor. Under the given conditions by me (tRD 8; 2,34v, 5-5-5-15) only one stick managed to reach 650 MHz stable (no 2 of the Cellshock D9GKX 4-4-4-12 kit). The other managed to be stable at 640 MHz (1x Mushkin stick with D9GMH, 1x Cellshock stick with D9GKX, 1x Cellshock stick with D9GMH). And one stick fell out of the line. One of the Cellshock 8500 5-5-5-15 D9GMH sticks only managed to reach 620 MHz stable.

damn, only one can do 650 stable out of 5 sticks. i need to get some more cellshocks preferbly with D9GKX.

my cellshocsk (GKX & GMH) react normal like all microns i think. I have no problem running them at any voltage. the more the merrier ...

memtest lock ups on DFI boards can potentially be overcome via clk fine delay tweaking http://i4memory.com/f80/dfi-lp-ut-p3...ne-delay-4743/ . Example, I had D9GMH which had troubles stablizing at 600mhz 5-5-5-15 2.19v at first but clk fine delay tweaks allow same ram to shine at 640mhz 5-5-5-15 at 2.19v and 645mhz at 2.23v 32M stable http://i4memory.com/f80/dfi-lp-ut-p3...743/#post82457 !

The clk fine delay settings don't seem to be doing much for me; I've found I can't raise the delay over about 280ps or so when trying to run 434FSB and my Ballistix at 650MHz C5, 2.38V. If I do change it higher than that the board won't post, and even at 280ps with that VDIMM setting I get 6-7 digit errors in memtest #5

aim for 1200-1225mhz 2.04-2.1v

[Shiranui Gen-An]

Zsamz it didn't sound like you had to mess with clock delays much to clock your Ballistix

[Shiranui Gen-An]

I can do 1200 with 2.05V on my Asus boards with the Tracers and the Dominator 1250 kit, but not on the DFI.

i set em real tight
to be honest i was verry lucky with my sets and my board just loves em
2 sets 1.99v is good for 1200 1 set i need 2.02v
i gonna play with d9 soon n see if i can break 12.5k in everest

you try cas 4?
? bios you on

[Shiranui Gen-An]

? bios you on

Haven't bothered with CAS4 on the DFI, I know the Dominator kit can do 600MHz CAS4 on the Asus boards with 2.40V. I can't get the DFI to do anything with them though. I'm on the latest BIOS from September.

anything with d9gkx is a pain
i got some high binned d9gmh too thats a pain must be a gkx cousin
but if dfi really gave a crap they can fix it
they got d9gkx workin on the x38 with bios update n special settings
either coders jumped ship or they dont care since d9 is eol
try playin with cas 4 your only hope lol

I know the LT and the UT are only supposed to differ in terms of cooling, but looking at yours and eva2000's results compared to mine, I have to wonder if the UT isn't better.

[neo mike]

From all i have read about dfi the ut p35 is the best memory overclocking board ever made, after that very mixed reviews on dfi boards, but i guess the ut 35 is like sweet overclocker, read many reviews on it.

[CryptiK]

Yes I have seen some people really singing it's praises, also my old P5K Deluxe was a good ram overclocker, and now it appears the UD3P is the new great ram clocker. The M2F is ok, but I can't get any ram over 666 MHz, all my kits just stop there - I can't bench more than 660 MHz (very unstable) and 666 MHz is max screen. I find it strange all my kits just stop there, which shows it is a board limitation. It would be nice to have a UD3P to use. It would be even nicer if Asus improved the ram clocking of the M2F I already own

Oh by the way Shiranui, I got my GKX to hard lock in SPI32M by trying to run 621 MHz on 2.1v.

[neo mike]

Yeah i have hear alot of great things about the ud3p, acually thinking of getting one myself, kinda tossing around what board to get, but the ud3p is high on the list, and its priced very cheap, but im having bandwidth problems with my ep45 ds3r gigabyte, so im a little weary of another gigabyte board. My Ep45 ds3r acually overclocks ram pretty darn well, but my everest scores suck for the fsb and memory speed im doing, and i dont know why.

[CryptiK]

Are you running the lowest PL you can and have all the chipset optimizations enabled and set on the most aggressive settings? The P45 can pull some decent numbers if you do that.
Also remember Everest scores mean next to nothing, it's just a synthetic benchmark, sure its nice to break 11K, but run some SPI32M, then you will see real world performance of your setup.

To see how your board compares (you can mimic my settings you run D9) here's a SPI32M at 445 FSB, ram at 534 MHz @ 5-5-4-12, PL8, all chipset optimizations on most aggressive settings:

[neo mike]

I have my timings as tight as they will allow, the lowest pl i can run is 8, i tried the trd pull ins etc, cant run lower at the fsb and memory speed im running, i know everest dont mean nothing, well i wouldnt say it means nothing, but it does show how you memory bandwidth is doing. With 515 fsb, memory speed of 1288 pl 8 5-5-4-12 trfc 40 i should be high 10,000s if not 11,000, im getting 10,300, something is wrong, i know this bios very well now, i have all set for top performance, i just dont get it, i will try your settings and see what happens, report back.

[neo mike]

my final time on 32m pi was 35.279 at my 24/7 settings of 510 fsb, 1275 memory 5-5-4-12, dont know if that is anygood or not. Ok my time with your exact settings 10.829s. So im seeing the fsb affects the times ?

[CryptiK]

See in the SS I posted my final time for a single SPI32M run is 11min 59.468sec? Are you saying it took you 35min to run a 32M? There is no way it only took 35 seconds. Are you using SuperPi 1.5xs? Can you post a SS?

For 1M I get 11.547s at the same settings I did the 32M run at.

[fatguy1992]

Could someone tell me what is better for RAM overclocking, Gigabyte EP45-UD3P or the EP45-Exteme?

Thx

[neo mike]

Sorry bro didnt post right, my super pi 1m time is 11.747s, my 32m time is
12 10.594s, so your board is a little faster, or memory, but is very close., at these exact setting what is your everest score, this is where you will blow me away, i will show you how bad my board is ? Im getting 9100 read, and 56.5 latency.

[neo mike]

Well fatguy i have read several reviews on both of those boards, i would lean a little toward the extreme, but its like really close, but a big price difference, the ud3p is over $100 cheaper, i vote for the ud3p.

[fatguy1992]

Thx, well its acutally about $80 cheaper were i'm looking , but I get what ur saying. Still thinking...

[fatguy1992]

BTW I just got 1 of my Cellshock sticks 2 1280MHz 5-5-5-15 W/ 2.2v. So much better then my Dominator - can't even do 1200MHz 5-5-5-15 W/ 2.3v.

[neo mike]

sounds great, glad to hear that. You know the world record on ddr2 was broken on the ud3p, what more you want. There is a thread here somewhere on that board, i think hicookie got it to 670 fsb. What cellshocks you have ? 1066s ? or the cas 4 1000s ? Here is the link to the ud3p ...http://www.xtremesystems.org/forums/...d.php?t=203272

[fatguy1992]

Yeah I remember that WR. I'll get the UD3P. Also I have PC2-8500 CL5's. Stock vdimm is 2.3v, so 2.2v to 2.22v for 1280MHz is pretty good i think .

I'm running a bench so I cant give a SS till later, but I get 94XX MB/s in read/write/copy and 53.9ns latency at the same settings.

What board do you have? I keep thinking it's a UD3P for some reason but I see form your comment above you don't own one. Making a sig with your gear & 24/7 settings would help sometimes when asking questions etc. My advice would be work on your chipset settings to make your board as efficient as possible.

@fatguy - I have not seen much of the EP-45 Extreme (haven't looked nor noticed), except for a couple of nice results, but the UD3P is going very well. It's also in a more reasonable price range and represents better bang for buck.
