divider of 100 is just for cpu oc. but when i set proper dividers between max cpu oc and rams oc then wouldnt it be different?

setting high HTT, and a divider (150 and lower especially) requires loose MAL/RP otherwise you'll get instability usually. Even if you are only finding CPU max, when you set a low divider you need to loosen MAL/RP. Above 300htt, it becomes even more critical. MAL=8 and RP=6 is a good start. I have to run MAL=11 and RP = 7.5 to find stability at 330HTT+ with a 150 divider :)

err..looser ? as in 200,166,150 needs to be loosen mal/rp?

 

abit confused with the relative terms

 

ooops

what TMM is saying is that MAL and RP must be loosened as the HTT is raised. Regardless of CPU speed and what divider you are using.

 

300HTT @ 5.5ns is very tight for RP. Prolly need 6-6.5ns at least, as TMM states that will increase the higher the HTT. So when you hit 320-330HTT, you will need to continue to raise MAL and RP.

i see...

i am using 9/6.5 .

 

MAL must be 8 or 9 before i can even boot.

 

thanks

Hey guys, tryin' again with these settings (taking a cue from recent posts to lower my Preamble and Max Async a bit more) and I also knocked my LDT up another notch.

 

Currently I'm running Dual primes (only have been for a couple minutes but we'll see) CPU is at 50-52C, PWM IC is at 53-54C. Here are my settings if anyone wants to examine them:

BIOS Settings:

 

FSB Bus Frequency............................. - 250

LDT/FSB Frequency Ratio....................... - 4x

CPU/FSB Frequency Ratio....................... - 12x

PCI eXpress Frequency......................... - 101Mhz

 

CPU VID StartUp Value......................... - Auto

 

CPU VID Control............................... - 1.500V

CPU VID Special Control....................... - 104.8% (1.57V Total)

LDT Voltage Control........................... - 1.40v

Chip Set Voltage Control...................... - 1.62v

DRAM Voltage Control.......................... - 2.87V

 

DRAM Configuration Settings:

 

DRAM Frequency Set............................ - 200/RAM:FSB/1:1

Command Per Clock (CPC)....................... - Enabled

CAS Latency Control (Tcl)..................... - 3

RAS# to CAS# delay (Trcd)..................... - 4

Min RAS# active time (Tras)................... - 8

Row precharge time (Trp)...................... - 3

Row Cycle time (Trc).......................... - 11

Row refresh cyc time (Trfc)................... - 16

Row to Row delay (Trrd)....................... - 02

Write recovery time (Twr)..................... - 02

Write to Read delay (Twtr).................... - 02

Read to Write delay (Trwt).................... - 03

Refresh Period (Tref)......................... - 4708

DRAM Bank Interleave.......................... - Enabled

 

DQS Skew Control.............................. - Auto

DQS Skew Value................................ - 0

DRAM Drive Strength........................... - Level 5

DRAM Data Drive Strength...................... Level 3 *15% Reduced*

Max Async Latency............................. - 9ns

DRAM Response Time............................ - Fast

Read Preamble Time............................ - 7nx

IdleCycle Limit............................... - 128 cycles

Dynamic Counter............................... - Disable

R/W Queue Bypass.............................. - 16 x

Bypass Max.................................... - 04 x

32 Byte Granularity........................... - Disable(4 Bursts)

 

Froze solid again so I lowered the voltage, PWM IC was up to 56C, I'm beginning to think this is a heat issue, as insane as that is with the fact that my room temp is 73F.

 

Anyway, editing my settings above to reflect what I'm running now. If it fails or freezes again, I'll lower the LDT to 3x and lower it's voltage back to 1.3, try again.

 

ADDED IN BY EDIT:

 

Did it again at the lower voltages. I'll try again later tonight, probably bump my Max Async/Preamble up to 10-8 see if that helps, I dunno, I think this thing just plain ain't gonna do it. Wouldn't surprise me.

tip* mount a fan over that PWM area and see about replacing your chipset fan with the one in H_G's sig.

As I've said in several threads, just not this one, my PWM IC has a fan blowing at 2800RPMs over it. That was WITH that fan. And Chipset is hardly an issue at 39C idle (ish) - 43C load.

Gonna try these and see if it works, doubt it but hey, ain't like I got much else better to do. The Opty/Asus system is basically done until I can get it a PSU that will allow me to OC, and I'm not about to go through the BS of putting the Opty back in this board yet.

 

I shall return with news of yay or nay soon.

 

Well, my calculation was right on the CPU 3.005GHz, but the RAM is only at 231MHz ::growls:: Ah well I'll prime it and see if it passes. Doubt it. I'm counting on the usual 8-minute-freeze-solid

Hey guys, stupid question. If Everest is detecting my individual core temps and Core #1 is at 66-69C... that's why I'm freezing ain't it? Think I'm fixing to see 70.

 

Huh, Core0 failed after 6 minutes... never happened before, Core0 always fails second. Very odd.
