sorry...that was an easy one...
now back to the memory thread...2 stick of 512mb pc3500...can i have one Leo? what about your old ones? are you gonna sell it? lmk...hee hee

Whew, I did a lot of testing. You bet I'm keeping both 3500 sticks But I am going to sell the 3200c2 stick, so pm me if you want it before it goes onto the For Sale forum
Leo

PS: I just put up my dual-XMS3500 results, in this thread

 

[THUGSROOK]

....got my two 256mb sticks of Corsair XMS3000 today

ill be testing stick #1 today, stick #2 tomorrow, and then both sticks to see how they do as a pair.

these sticks should run better then 512mb sticks cause they only have half the memory chips right? ~ we'll see

 

[SupermanCK]

go go go...storm the front!!!

 

[THUGSROOK]

fresh out of the plastic box ~ 400ddr cas 2 2 2 7 ! :Q

and still going...

 

[THUGSROOK]

cas 2227 was good upto 405ddr :Q
wall time for all 11 tests was only 17 mins! :Q

...this is a really nice stick of ram so far

 

[THUGSROOK]

1st stick is done
ill retest it tomorrow to see if it can go further then ill start on the 2nd stick.

 

[Mikki]

I like the new format, looking forward to your results!

 

[Mikki]

CAS has one heck of an affect of ddr speed, jeez...:Q

Hey Thugs,
I just finished testing @ 2.7V (two XMS3500 512mb sticks) and passed Memtest with CAS 2-2-2-7 at up to 145fsb:386ddr!

 

[THUGSROOK]

kewl

a couple things ive learned so far from all this....

*2.7v will eventually fail from heat (on p4b533 boards)
*512mb sticks suffer from heat and need to be tested for X hours (at least 5)
*256mb sticks have half the chips, arent as hot, and dont fail @ X hours from heat
*memtest86 aint perfect (it doesnt heat the ram)

 

[Leo V]

Very interesting. It sounds like 2.7V is mostly bragging rights... so I'm going back to testing more 2.6V settings

 

[THUGSROOK]

no no no dont take my word for it ~ run a few tests...

do your 2.7v speed for 5 hours ~ even if it passes, test some memory intensive apps.
or just plain watch a full screen divx movie
itll be be very "heat sensative" at some point and lockup.

hell, just raise your room temp a few degrees and youll see what i mean :Q

 

[Leo V]

Nah, I believe you I will run scientific simulations on this PC, and I don't want any funny bits anywhere.

Back on earth (@2.6V) I have just passed MemTest @ cas2337, 144fsb:384ddr. Even at 145fsb, it gives me a couple errors at 65%. So I have to choose between 2.45ghz/cas2337 versus 2.50ghz/cas2.5337... can't wait for GB...

EDIT: I just tested my mini-benchmark, and cas2337 offered no advantage over 2.5-337... I guess I'm just going back to 2.5ghz and 2.5-3-3-7.

 

[THUGSROOK]

try messing with the SDram Idle Timer~
0 slows the ram a bit
64 is best performance
any setting is more stable then "infinite"

HTH

 

[Leo V]

I tried 64, and I couldn't detect a performance difference with my program. However, if it's more stable than Infinite, I'll switch to it anyway. Thanks for the advice!

I'm successfully running 2 x 512MB sticks of Corsair XMS3200c2 at DDR400, CL2.5-3-3-7, using 2.7V. This voltage didn't give me any trouble during my Memtest86 test. I ran for over 18hrs at this voltage with zero errors. Temps were in low to mid 80F range during this test. This was in late September in Sunny SoCal with no AC.

WOW...which dell LCD is that?..sorry to bring this off-topic for a brief moment...and the image quality is excellent...

nm...found out it's a 19"...

 

[THUGSROOK]

working on the 2nd stick today~

got 413ddr out of cas 2227 :Q

 

[dbwillis]

Nice Thugs!

geez...i barely could run 418ddr with mine but with cas 2.5-3-3-7

 

[THUGSROOK]

all done testing the 2nd stick

ill retest it tomorrow and then ill get started on testing 2 sticks

 

[LukFilm]

What's faster? 2.5-3-3-7 at 440MHz or 2-2-2-6 at 400MHz?
