Issues with RAM Dividers

Hey guys,

I have a question concerning memory dividers while overlocking. I am using a DFI Lanparty Nforce 4 Ultra D with an Athlon 64 3000+ and 2gb of OCZ Ram. The FSB is running at 288 Mhz to 2.6ghz out of the processor (that is a 9x multiplier). The ram is running a 3/4 Multiplier. This is forcing me to run the ram at a Cas Latency of 3 to keep it stable. I have tried to run the ram at a low multiplier, such as 7/10 and even lower. But, it will not POST when I attempt this. My previous ram, 1gb of OCZ ram, had no issues running at 7/10 and even the next step down (I can't remember that divider off of the top of my head), but the old ram would not run at 1/2. Any suggestions as to what the issue is? Thanks in advance.

post all the settings you have set in the bios in the memory page

what slots are you using?
 
The ram is installed in slots 1 and 3. The other information you requested is as follows (I used the abbreviations where applicable due to lack of paper space):

Dram Frequency Set 150 Mhz or Dram/FSB:3/4 (This is the setting giving me issues)
CPC: Auto
Tcl: 3.0
Trcd: Auto
Tras: 08
Trp: Auto
Trc: 07 Bus Clocks
Trfc: Auto
Trrd: 02 Bus Clocks
Twr: 02 Bus Clocks
Twtr: 02 Bus Clocks
Trwt: 03 Bus Clocks
Trcf: 3120 Cycles
Twcl: Auto
Dram Bank Interleave: Enabled
DQS Skew Control: Auto
DQS Skew Value: 0
Dram Drive Strength: Auto
Dram Data Drive Strength: Auto
Max Async Latency: Auto
Dram Response Time: Normal
Read Preamble Time: Auto
Idle Cycle Limit: 256 Cycles
Dynamic Counter: Disable
R/W Queue Bypass: 16x
Bypass Max: 07
32 Byte Granularity: Disabled(4 Bursts)

That is all the information under the DRAM Configuration Screen, hope it helps

im having the same problem im able to post with ram running at 166 in bios but when i try 133,100 it wont post......
 
you can try setting:
the Bank Interleave to disabled ,
the trc to 9
trcd to 3 or 4
trp to 3 or 4
2T timings (i think its CPC , not sure , disabled should give u 2t)

there should be a setting called "odd divisor correct" , try that enabled


if still doesn't work ,use the 133 divider
 
there a reason my computer wont post with memory divider@133,100

motherboard

msi k8tneo 2 (Newist bios)

Also has anyone known this mobo for reading bad temps
 
what kind of volts are you using for that memory?

i had allmost the same kind of memory proplems when i was testing some different memory setting, i noticed that when ever i booted to windows and cheacked the memory settings from cpuZ they were allways set to 243 mhz... odd. i tested them with all the dividers(100-250) no go. even tryed just for the hell of it, them at some tight settins , 2.5 cas and they ran with those settings, i was really supriced to see 2gb kit could run so tight settings
finally i got tired to fidle with the bios setting, so i desided to flash an older bios version and ta.da it worked.

have you tested the other slots?

bad plan, leave that setting alone until you fully grasp how a64's memory dividers work.

fluffy, i forget. slots 1&3 are the orange ones, right?

try setting the dram response time to slow to see if it helps with the lower memory ratios. sounds like you just have a picky memory controller.

if that doesn't work, set
Trrd: 02 Bus Clocks
Twr: 02 Bus Clocks
Twtr: 02 Bus Clocks
Trwt: 03 Bus Clocks
all to auto
 
Eclipse, the 1 & 3 slots are the yellow ones, not the orange ones (If I remember correctly). When I get a chance to pull my PC out of the desk and test on the kitchen table, I'll try setting some of these settings and changing the clocks. Thanks for the advice and I'll be back soon with results.

my bad. i always count the first slot as the one closest to the cpu. dfi labeled it backwards for some strange reason

use 2+4 then, the orange ones. yellow can give trouble sometimes
