memory dram frequency

post #1 of 6
Thread Starter 
Hello,

http://img156.images...yesyesnowhy.jpg

It Tells me, that my DRam frequency is 400Mhz (My ram are dual channel, so 400x2=800mhz. everything is fine)

BUT in my bios, there is a setting in the same page as FSB ratio it is called "Actual mem (DDR), MHz 666.7"

So i don't really understand If i'm running on 800mhz, or on 667mhz? Thanks alot.


P.S. I'm not an overclocker. But i know, that FSB ratio(1333) has something to do with my memory Mhz.

P.P.S. Is memory timings tweaking safe?

What does CPU-Z's Memory tab say? Multiply that value by 2 and that's what it's currently running at.

Also, the reason why it's multiplied by 2 is because it is Double Data Rate (DDR) memory. I mean, it's not because it's in dual channel mode. All DDR memory is Double Data Rate whether it's the original DDR, DDR2, or DDR3.

Ah yes, i just misspelled it


Cpu-z http://img156.images...yesyesnowhy.jpg


In bios i see fsb 1333 and dram 666.7

It is set on Auto (or standart, can't remmeber) but if i set it to a manual mode, i can make my fsb run at 1333 and my dram at 800.

So i don't know if I need to do that or no. and the most important: is it safe?

I don't know what you're doing with your links, but this is how they're turning out:

Code:
http://img156.images...yesyesnowhy.jpg/
It looks to me like you're copying the truncated text and then posting that as the link. Instead, copy the address from the address bar. Or just link me to the imageshack page (so, don't use img tags).

Or just tell me what CPU-Z is giving you for a "DRAM Frequency" on its Memory tab. That would be the easiest way to get the information posted.

Ultimately, just multiply the number by 2 that CPU-Z is displaying in the "DRAM Frequency" field in the "Memory" tab. That way, you will know what your memory is running at without having to rely on what the BIOS is saying.

As far as whether or not it's safe: I don't know because I don't know anything about your system.

As you can see, my FSBRAm ratio is 5:4. Should i tweak something, or is everything ok? Here are my rams info:

1GB

@ 400 MHz5-5-5-18 (CL-RCD-RP-RAS) / 23-42-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz4-4-4-12 (CL-RCD-RP-RAS) / 16-28-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)
@ 200 MHz3-3-3-9 (CL-RCD-RP-RAS) / 12-21-2-3-2-2 (RC-RFC-RRD-WR-WTR-RTP)


2GB

@ 400 MHz6-6-6-18 (CL-RCD-RP-RAS) / 24-51-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 333 MHz5-5-5-15 (CL-RCD-RP-RAS) / 20-43-3-5-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz4-4-4-12 (CL-RCD-RP-RAS) / 16-34-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)



Oh, and in CPU-Z, you can see, that my ram are working at CR T2 instead of T1.

Tell me every tweak i could use. Thank you. i really appreciate your help

I had a "680i SLI" board for a while (the top-of-the-line nForce 600 series), and I could easily change from 2T to 1T because my memory also enjoyed being tweaked that way. However, you have two different kinds of memory in your slots, so I wouldn't attempt it.

Anyway, CPU-Z says the clock speed is 400MHz which means it's at 800MHz, so it's all good. Plus, achieving a 1:1 ratio on an nForce chipset is almost not important at all. Instead, it's more important to shoot for tighter timings if possible.

However, if you're not going to overclock at all, then I recommend leaving everything as it is.
