Memory Speed Decrease?

[Fil]

I'm running in Dual Channel and i just realized on CPU-Z it says that my memory is runing at 157 Mhz instead of 200Mhz, how do i make it run at 200?

what mobo you got
and do you got a intel with 400 fsb 533 or 800?

He has an A64 3500+ (Good choice )

To me, it sounds like you have a divider set wrong. Search around in your motherboard. It sounds like your multiplyer is set to either 333, 320, or 5:4. If you see any of these, change them to 400, or 1:1.

I looked throught my bios and i went to Memory config and i changed it to run at ddr 400 it said it was 2:1 so i did and then i opeb cpu-z and it says its running at 157.3mhz. The multiplier is 11x200.

Memory should be 1:1 which is 200:200. 200Mhz = DDR400.
The base clock should be 200MHz.
HT link should be 4x200MHz (800MHz).

You are running 2 sticks of 512MB?
When did you buy your 3500+?

Yes i have 2 srick of 512 PC3200, but one of them is Cas 2.5 and ones is Cas 3.0 How do i make them both at Cas 3.0 Also Sisoft Sandra says im running single-channel and cpu-z says im running dual channel. WTF? anyways i have revision 1.02 if that matters
My ht link is set to 1000mhz, if i drop it to 800mhz will it decrease performance? and if i drop it to 800mhz will it have my ram running at 200mhz?
I bought my 3500 like 2 weeks ago

I would go into bios and look for a setting for memory timming.
Set it to a CAS of 3. Maybe it is trying to run both sticks at 2.5 by downclocking.

 

[Fil]

I set it to CAS 3 and then in Cpu-z its still running at 157 even when they are both running on CAS 3. In CPU-Z it says FSBRAM then beside it, it says CPU/15.0 what does that mean?

 

[Fil]

please someone helpppppppppppp!

that means you're running a 1:15 divider. try going into bios and setting any ram freqency settings to 200.

you can drop your htt to 800 mhz, the bus is very fast and has loads of spare bandwidth. i don't know if/how that'd help though.

I just tried running one module at a time and it was running at 200MHZ. Now when i put it to run in dual channel it decreases my speed down to 157MHZ. Is this because one is CAS 3 and one is CAS 2.5 I made it so that they both run at CAS 3 but its no help. I also set it to run on DDR400 in the bios but no help. So what do i do?

Are both sticks the same?

 

[Fil]

One is Samsung and one is "unamed" but they both are PC3200.

 

[Top Secret]

That *Could* be your problem. Not *ALL* PC3200 will work together. Ie, one of my Hyper X sticks won't even post with one of my Ballistix.

 

[Fil]

What if i put them to run in Single Channel? Will i see a performance decrease beacause i have an Amd 3500+ that runs with dual channel memory.

You mean as a trade off for 200mhz? I don't know. I wouldn't guess so. I think you should buy one more of whichever stick you determine to be better. But hopefully we can get some more opinions on this.
