Mushkin xp2 8500 @ 3 3 3 3 400mhz

[Alexontherocks]

Hi. I am unsure if this is the correct section to post in since many of you have achieved trully exceptional results. I have tried out several memory sticks and so far I have come up with some interesting results using a pair of 1gb xp2 8500 mushkin modules 2x1024.

I managed to downclock them to 400mhz pc6400 wth stable timings at 3 3 3 3 @ 2.45v I have also decreased memory subtimings to 25 6 10 8 2 8 2 3 2 (Trfc - Perfomance level - WTP - tWTR - tRRD - tRD_WR - tRTP - Precharge to Precharge)

I am still working on subtimings. Memory is orthos and prime 95 stable even though I have not posted screens (forgot the first time to dump the screen) :ROTF:

I hope someone can tell me how to further increase performance. Right now my system is a sprint runner. Every application opens and closes without even so much as a 2 seconds delay. Quite impressed with mushkin actually.:clap:

2.45v might damage or kill the memory in the long run
800 333 isnt really that fast, good kits can run 1000 333
when i read your thread title i actually thought you were running pc8500 333 :D
now THAT would be sweet :lol:

you should be able to get a lower performance level, no?
with ddr3 PL5 is possible up to 450fsb/1800 mem
not sure what pls work for ddr2 tho, maybe pl6 is really as good as it gets even with 800 mem speed?
ras to cas write delay of 2 clocks should be possible, no? did you try it?

[mad_skills]

With Intel chipsets higher MHz is better, so some 500MHz 4-4-4-4 with, let's say PL7, would be better than that 400MHz 3-3-3-3 for everyday setup.
I would do so and i agree with sayaa, 2.45V is too much for 24/7.:up:

[Data_]

You can also try 500 3-3-3-9 it needs 2.7V and join 500Mhz club. I do not force you to do it, barely to know limit. 500mhz 4-4-4-12 24\7 will be nice.

[Alexontherocks]

I understand....I thought it was a good result but apparently I was mistaken. At least I got some new ideas to try out.

Thanks for the imput I will post the results shortly. As I do not have time to stress with prime95 I will only run a pass with memtest86+. It should provide good stressing too.

[Alexontherocks]

I am currently running 500 mhz 4 4 4 8 CR2. Memtest86+ stable

[Yukon Trooper]

I have the exact same sticks. Most excellent indeed.

[Data_]

What chips?

[saaya]

should be micron...

[Alexontherocks]

ok...results from everest benchamarks 4 4 4 8 @ 500 mhz stock voltage

read: 9245 mb/s
write: 7278 mb/s
copy: 7557 mb/s
latency: 52.9 ns

I tried CR1 but it would not post with 2.45 /maybe more?). I also tried 4 3 4 8 and still it would not post @ stock voltage.

Will a run with 2.7 kill my memory? I have a feeling this kit will make it in the 3 3 3 3 500mhz club.

[Alexontherocks]

ps Yukon Trooper....how far have you pushed these ram modules? had any luck in running 4 4 4 @ 500 mhz with CR1?

[saaya]

2.7v... depends how long youll run that high.
some kits might die after some benching with 2.7v, but its rather unlikely.
ive been benching for a weekend with 2.5v straight without any degradation... that was 950-1000 333 :D
but that was a handpicked kit of our 1150s...

[systemviper]

whats the mushkin number on those chips, they sound sweet.

Donate some of those 1150's?? lol

I have had 1 OCZ kit and 1 Corsair kit go bad after benching 2.65v with our reverse cycle 3hp air con blowing into the case full noise.

My good Dominators are still going, and do 1066 4-4-4-10 CR2 at just 2.34v
though to keep them cool (theyre pretty warm little buggers) I just run 1040 4-4-4-12 only needing 2.28v

I find for good all round preformance, max out mem frequency at a reasonable voltage, say 2.3v, using CL of 4. Then from there start to tighten up subtimings.

I leave tRFC at 52 for this, and only tighten up after I have a good frequency/voltage and good timing combo, because it really inhibits your preformance dropping this too early, and you dont gaint alot by having this loads tight. After I have my prefered settings I just drop this down to about 40.

Previous decent score without paying too much attention to subtimings got me: 11023-7317-7999-45.9ns on everest using 1080 4-4-4-12 15tRC and 45tRFC

I've never tried to go as low as I can, but I'll try when I get them back from RMA. I have to wait until my OCZ Plats rev.2's get here before I can send my Mushkin sticks out. One died on me and the other is fine. It's more my own fault than anything else, though. I didn't have any fan on them, so the D9 chips were only going to last so long without active cooling. Oh well, I've learned my lesson the hard way. :)

we musta had the same batch yukon
i never went above 2.24v + had 2 90mm fans on mine they never got to 30c
lost 3 pairs last year n the ones i got this year were deffective from day 1 i bet you got them from ncix
my last pair did 3-3-3-8 @ 830 2.24v but anything above 850 gave me errors on day 1
btw them ocz plats can do 5-5-5-15-4-50 @ 1000mhz

[Alexontherocks]

ok.....some testing done: 600 mhz 5 4 4 12 on stock voltage 2.35v. stable memtest86+ full pass

Can't get to cas 4 with stock I guess I will have to resort to thermalright's hr-07 and more volts.

good results in everest. I would like to break the 10000 mb/s barrier but I guess more tweaking is necessary.

P.s. I have a p5k premium and have experienced with bios 0404 some multiple boot issue. I press the on button, the screen is blank, the keyboard flickers and the fans are on. Then it turns off and restarts on its own. It does this a couple of times (maybe 3) and then posts succesfully. Any ideas?

[Data_]

Better to leave 600MHZ 5-5-5-15 2.2V 24\7 if its stable. 2.35V can kill your sticks. Did you find that this voltage is quite high for quad?

[Alexontherocks]

2.35v is considered within safety range as visible on the stickers.

I will try to do as you say.

[bl1zZ]

Had a kit of G.Skill 6400CL4D-2GBJS here.
They did 1080 3-4-3-3 on a Gigabyte GA-G1975X 32M Stable at 2.56v...
I look if I can find the screen of it

[naokaji]

I tried CR1 but it would not post with 2.45 /maybe more?).
Will a run with 2.7 kill my memory? I have a feeling this kit will make it in the 3 3 3 3 500mhz club.

Forget Command Rate 1 with ddr 2 on intel chipsets, it wont really work.

2,7V? I've had ddr2 at 3,3v even for a few minutes, but 3+v is more like who fries his ram the fastest competition than something else... 2,7 or even 2,8 is ok for short time benching with appropriate cooling and provided you have some el cheapo back up ram just in case.
3-3-3 @500, lots of ram can do it, but most that can takes voltages beyond good and evil to get there.

[cdawall]

best my cheap patriots could do was 3-3-3 @366mhz 2.3v and my AMD can't do a high HTT so no max oc but i ran 5-5-5 @ 522 2.2v nice little sticks IMO

http://img.techpowerup.org/080428/368361.png

its not bad considering they stock @ this @ 2v

http://img.techpowerup.org/080428/untitled.png

here is 522 5-5-5 @ 2.2v

http://img.techpowerup.org/080425/522.png

not bad for $20 ram

[zanzabar]

this is what 2 $43 team group kits do with 2.15V

but thats with pl8, i wish that i could go pl5/6/7 like u guys can

[zsamz_]

this is what ballistix can do with 2.03v:D

[zanzabar]

is that with 2gb or 4gb

[cdawall]

thats fine here is what some dell ram i got with my K9A platinum and HDD i ordered online can do

http://img.techpowerup.org/080514/533@800 loose.png

thats DDR2 533mhz

part number: m378t6553bz0-cd5 (http://www.parts-quick.com/m378t6553bz0-cd5.html)


i'm about to try for 1044mhz on them :rofl:

[zsamz_]

is that with 2gb or 4gb

2 gigs i cant go so high with 4 gigs only on the p35 my x38 can do 1200++ with 4 sticks
well i can do it with dfi p35 but needs too much juice
i havent pushed my ballistix over 2.24v:eek:

[saaya]

965 can do 4 sticks at 1200 as well.. it just needs areally good sticks and a lot of tweaing :D

[Nanok]

I was bored, and wanted to see how low i could go with 800mhz
Here is was i came down to.
3.2.2.5@800 with 2.4V

2mb of extra cache helps to calcute Super PI, nice clocks...

[zanzabar]

here is the starts of my summer oc with 4x1GB of ram, and no tweaking pl7

and 14.717 pi:up:

[zsamz_]

you need to push more zanza try 333/800 divider i did 1200+ 4 stix on dfi-x38

[zanzabar]

the point was cas3

[zsamz_]

the point was cas3

my bad lol
i gonna try n see if my kingston value can do cas 3 lol
