OK i just got 2X 512MB PC3500 Geil ram, the numbers on the sticker (on the side of the ram) says
CAS 2 6-3-3 1T @ DDR433Mhz PC3500, 2.5v-2.9V.
if i run cpu-Z i get these values

Frequency 133
FSB:DRAM 1:1
Cas latency 2.0
Ras# to Cas# delay 2
Ras# precharge 2
Cycle time (tras) 4

So what should i set the timings to in my bios..
for 2 more days im running an athlon 2400xp, getting a 2500barton therefore the low frequency..

but should i set my timings to? should i raise those 2's to 3 and cycle time to 6?

If nforce2 chipset, i'd suggest memory timings (CAS Latency - tRCD (RAS-to-CAS delay) - tRP (RAS Precharge) - tRAS (Active Precharde Delay)) of <A HREF="http://www.geekextreme.com/modules.php?name=Content&pa=showpage&pid=30" target="_new">2-2-2-11</A>.

I second that opinion if you can get 2 2 2 11 and its nforce use it.

If I glanced at a spilt box of tooth picks on the floor, could I tell you how many are in the pile. Not a chance, But then again I don't have to buy my underware at Kmart.

I'd leave it. You're running the RAM synchronously with the CPU bus which is usually a good idea. 133MHz is DDR266, the standard bus speed for your 2400+. The 2500+ runs a stock bus of 166MHz (DDR333) and your upgrade will reflect that change. The RAM just might run at your current lower latencies using that speed.

If you are using an nforce2 board and want the best performance use the tras 11 setting. More and more people are learning this. It first came to light about 6 months ago reasonably common knowledge among nforce2 enthusiasts.

If its not nforce2 stick with lower timings like 2-2-2-6 I belive 2-2-2-6 is the best timmings (performance wise) on a non nforce2 platform.

So if its nforce2 try 2-2-2-11 or 2-3-3-11 or 2.5-3-3-11 0r 2.5-4-4-11

ok i got the timings to 2-2-2-11 now what would be the best way to test it? would that be to run 3dmark03 with tras from 4 and up to 11 to see whats best? or is there an easier way?

Maybe my mobo is just being a bitch but every time I change the precharge delay past 7 my comp will not post.

GeekExtreme and MadShrimps used 3DMark2001SE (in addition to other benchmarks) for performing this kind of test as opposed to 3DMark03; just an observation.

One I do know that those timmings 2-2-2-4 will work and probably will pass the memtest86 but you will get software corruption. Im going to try f-ing with my timmings again tonight, 2-3-3-11, 2.5-3-3-11, 2-4-4-11, and 2.5-4-4-11 to see what happens..

please post what you find!!
im getting my barton 2500 tomorrow hopefully..

but regardless of beeing able to run 2-2-2-4 , 2-3-3-6, 2-2-2-11 theyre still good ram and will make it possible for me to OC to barton 3200 right??

i mean im hearing something aobut Geil != Asus A7N8X so im getting a bit scared, and debating if i should send em back, cause i only have 8 days to do that in..

ok i have run memtest86 at these values:

2-2-2-5 - no errors 1024MB - 1043MB/s

2-2-2-11 - no errors 1024MB - 1058MB/s

i ran the standard test in both runs,, so how do i know what setting is better for me??

i mean would that be to run the 3dmark01 or 03 or??

Reply to kemokim

In your memtest86 run 2-2-2-11 generated the best results. Go ahead and run 3dmark01. I think it's pretty clear from what i've seen from a number of sources that 2-2-2-11 would be the recommeded timings for this chipset, if obtainable.

Just put together another a7n8x-deluxe and barton system and was able to do those timmings just fine until when I past the 200 clock in dual channel and that when the errors started. I did notice that the northbridge HS was rather hot and probably a better cooler with make it go father than 200.

Just remember Cas has the biggest impact on performance by far so keep it at 2. Only use 2.5 if you cannot get cas 2 with any other combo. In other words I think 2-2-2-6 would preform better than 2.5-2-2-11 but 2-2-2-11 should be better than 2-2-2-6

True and bumping the precharge delay that high will also have an effect on the bandwidth too. I tried 11 and my scores didnt change.

Did you try it at 11 using 2-2-2 timmings ?

I've seen this topic in nforce forums and everyone who tried 2-2-2-11 scored better then 2-2-2 (?) There is a link at the top of the thread showing this.

Not saying your score did not change I'm just suprized is all.

So I guess bumping the precharge delay to 11 should have a positive impact on performance when using 2-2-2
