What the highest memory bus you have attained? What memory are you using?

[John]

I have (2) 256MB Samsung Original PC2700 modules that do cas 2.5-3-3-6 @ 200MHz 2.9v, but I am looking for something that will do at least 215Mhz or better. Corsair XMS PC3200 is probably using what I have now in addition to the heat spreader.

 

[Bobbyeyes]

I too am anxious to get the results of this poll
especially the results at default memory voltage

 

[Duvie]

(2) sticks of PC2700 ddr running at 410mhz ddr on Asus P4S333 sis645 chipset....2.7v...decent timings...always left at cas 2.5 cause that is what it is rated for...


Sad thing...Those 2 sticks wont do anywhere near 400ddr on epox mobo with 2.8v and lowest settings....

U P D A T E

Corsair XMS3000 cas 2.5/3/3/7 (so far) 2.6v (my boards default) 426ddr

*thats all she can do 12 hours prime95 stable

Haven't tried too many different ones. I have one 512 Meg Samsung PC2700 that does DDR400 pretty easy. I've had it @ DDR412 and thats about as far as it will go. I also had an OEM Samsung 512 meg from Dallasmemory that went into a friends PC (same mobo). Does DDR400 also, never tried any higher. For more, you need to get into the more $$ stuff like the Corsair.

where did you get your corsair 3000?

1 stick generic/no name PCB with Samsung chips, got 195 mhz with DDR V at 2.75 on an Abit KR7A

how does one overclock memory, or am i asking the wrong question....?

Raise your fsb and keep good memory dividers.

It works like this:

fsb/d1*d2*bit=memory bandwidth
fsb/d1*d2*2= DDR memory frequency

I hope that helps.

Just so you know:

fsb = front side bus
d1 = divider #1
d2 = divider #2

Excellent, now if I could just figure out how to change d1 & d2 on my A7M266...I'm not even sure if it's possible

D1 and D2 are your memory dividers.
For example, if I'm using a 4:6 divider, D1 would be 4 and D2 would be 6.

Adjusted in the BIOS? Forgive my n00bishness

Yep, you'll see it right near your fsb changing options.



...By the way, the best I've done so far is DDR435.
I'm getting some TT active ramsinks for my RAM then going to see what I can do. Hopefully I'll hit my DDR480 with 2.9v vmem.
If not, it's off to buy either some mushkin or corsair platinum.

DDR480 are you CRAZINAZY??? there are no ram out there that can even go about 450...
as for me...i have corsair xms pc2700...i have been able to run it up to ddr426.67 with fsb160 3:4 ratio...even with 2.5v...but i needed more vcore that i would preferred...

 

[THUGSROOK]

damn sam! we are in quote hell here!

are we talkin about a SiS board?
SiS boards have a Cas 2.5/4/4/7 option that may actually allow for a higher DDR overclock than a i845 board. actual performance isnt any better tho obviously.

was i OT?

 

[mastertech01]

I have achieved a BIG FAT 133MHZ with a 1GB stick of Nanya PC2100 on my Tyan Thunder! WOOOOOOHOOOOOO!

 

[CrawlingEye]

I've seen DDR500 all ready @ 2.7v vmem with no extreme cooling with Corsair XMS PC3200.
I'll be using more cooling than he was, if this sammy won't do it, I'll be getting either Mushkin PC3200 or Corsair XMS Platinum PC3000 CAS2 (winbond chips)

 

[Bobbyeyes]

CrawlingEye

where have you seen this DDR500
Corsair XMS Platinum PC3000 CAS2 ?

wow i like that. furthermore with stock voltage. hoping i would do something like that with my Corsair XMS3200.
even if i have to modify a bit the timing setting of my memory...

 

[dbwillis]

Highest Ive gotten is DDR450

P4S533/150fsb, 4:6, 2.5-4-4-7, 2.7v, Mushkin level 2 DR266

why don't you try to down a bit your memory frequency & up a bit your FSB? normally it is more powerfull involving better benchmarks.

 

[THUGSROOK]

im sure hed love to - but his mommy board said no

 

[Labdog]

it is not a mommy board issue but a processor one.

 

[dbwillis]

Yeh, the board isnt sable above 150fsb..I tried booting 166fsb and XP blue screened....thats why Im getting a new 1.6a and P4B533 tomorrow (well actually Thugs, Supermans and Duvies tests, results made me do it!)
