RAM overclock or downclock?

post #1 of 6
Thread Starter 
Sorry if I post in the wrong section.

I oc my i7 920 to 3.3 with BCLK of 160x21

In DRAM FREQUENCY I choosed 1604MHz, I could choose from lower and higher values obviously, so:

Do you thin that I may hurt my RAM that work at stock freq. 1600MHz if I selected 1604? The difference from stock is only 0.004MHz.

My ram is CORSAIR XMS 1600MHz 9-9-9-24 1.65v 3x2GB in triple channel.

My system is i7 920 on ASUS RAMPAGE II EXTREME.

Thank you for your help in advance.

A 4Mhz OC won't hurt it, but if the RAM was Factory OC for 1600, theirs the slight chance it might throw an error or two. Shouldn't, but i figured i would throw the possibility out their.

Thanks a lot, so would be better to downclock it when going up with BLCK for high overclock?

Suppose I want to reach 3.6 or 3.8GHz, the RAM freq. will be higher then 16xxMHz or lower.

In your opinion is better to choose lower values? I.e 1540 or smilar near 1600Mhz factory?

First off, it's best to use the Multi to OC, that way the RAM is left alone and the Newer iCore's don't like a bunch of BLCK turned up.

And its better to do 1400Mhz then 1650-1866Mhz on RAM that is made for 1600. You can OC RAM, but you need a Stable CPU first.

PimpSkyline thak you very much for your patience, it's very kind of you.

This is my actual BIOS settings:

i7 920@3.6Ghz

CPU Ratio=172
BCLK=21


1) DRAM FREQ: 1379MHz ( I can choose from 1035 and 1724, as you said before I underclock it a bit to 1379, being my RAM 1600MHz). Here, in your opinion, is better to select AUTO or use 1379?

2) UCLK Freq.=2758 (according with 2xDRAM Freq.). Better to let AUTO?

3) QPI Link=6208MT/s. Better to let AUTO?

4) DRAM Timing Control:

DRAM CAS# Latency = 9
DRAM RAS# to CAS Delay = 9
DRAM RAS# PRE Time = 9
DRAM RAS# ACT Time = 24

Being my RAM 9-9-9-24 I choose above setting. Also here, better to let AUTO?

Thanks a lot again,
Riccardo

1. 1379 is fine
2. AUTO is ok, but it depends
3. AUTO ^
4. AUTO, now i know that is fine, cuz the RAM will set it.
