Can get system to post at 450MHz... running 24/7 at 430

[davidos]

Here are my settings... Is there something with the DS3 that has trouble at 450MHz? Should I try a divider? (I'm not too familiar with those yet). Doing 3010GHz fine... Wanna see if I can push it a little more!

In BIOS second screen disable the thermal features (C1E, EIST, etc)

CPU Rate 7x
CPU Host ENABLED
CPU HOST FREQ 430
PCI-E 100 (or AUTO)
CIA2 DISABLED
System Memory Multiplier 2x (that's the 1:1 option)
DRAM TIMING MANUAL
CAS 5
RAS TO CAS 5
RAS PRE 5
TRAS 15
ACT ACT DEL AUTO
RANK WRITE AUTO
WRITE TO PREC AUTO
REFRESH TO ACT 0
READ to PRE AUTO
MEMORY PERF NORMAL (try also FAST or TURBO as you go above FSB400)
DIMM OVERV +0.3V (2.1V)
PCI-E OVERV NORMAL
GMCh OVERV +0.1V (or 0.15V)
FSB OVERV +0.1V
CPU OVERV 1.375V (try up to 1.40V also)

You have DDR2-800 rated ram, and trying to boot at DDR2-900.

Can you lower the memory multiplier and see what your max FSB for your board is?

yes I have DDR2-800... Can you explain lowering the memory multiplier a bit? Thanks!

I have the same ram OCZ Platinum. The ram is stock @ 2.1v. You need to up the voltage to 2.2v to get 450.

There is no lower multiplier than 1:1 on his chipset.

In my case the Platinum would only work stable until 1.95V with the Gigabyte boards. Several other members had the same issue.

I can run the Plat. on my 2nd rig up to 450MHZ using 5-5-5 and 1.95V.

Davidos, are you using BIOS F5?

Try also this:

CPU Rate 7x
CPU Host ENABLED
CPU HOST FREQ 430
PCI-E 100
CIA2 DISABLED
System Memory Multiplier 2x
DRAM TIMING MANUAL
CAS 5
RAS TO CAS 5
RAS PRE 5
TRAS 15
ACT ACT DEL AUTO
RANK WRITE AUTO
WRITE TO PREC AUTO
REFRESH TO ACT 0
READ to PRE AUTO
MEMORY PERF TURBO
DIMM OVERV +0.15V or +0.20V
PCI-E OVERV NORMAL
GMCh OVERV +0.15V
FSB OVERV +0.15V
CPU OVERV 1.40V

What timings? Also, is yours the revision 1?

 

[tran1981]

Yeah, mine is revision 1. It won't post if I don't change it to 2.2V @5-5-5-15 w/ 450. I ran memtest for couple passes. I have C2 DS3 so I don't know if it fix some issue with ram. I tried to run @ +.2V but it gave me reboot than @ +.3V (no reboot). I'm still trying to configure. I can run 400 at normal everything stable (Orthos blend) for 24hrs. I have E6400.

Edit: I didn't try anything more than 2.2V. I don't want to void warranty on the ram.

Great. thanks for the info... I didn't try 2.2v (which would be +.4 volts in bios) but when I tried it at 2.1v the computer wouldn't even boot... The memory seems to be pretty good so far!

 

[davidos]

Well I bumped it up to 445 without changing anything except a hair more voltage on the cpu and it booted without hesitation at 3110GHz... running stable after Orthos and 3dMark '06.

Still can't get 450fsb to boot.... it's weird... almost like it's a bug in the bios or some small glitch with a setting... I'm going to try 451MHz to see if that'll boot.

 

[darkhorror]

I am having a problem at 450x7 also, mine boots, but when I run orthos it would freeze, then I would have to reboot, sometimes it would post sometimes not. Now I haven't really tried to do much with it just lowered it down to 420.

 

[bobsmith1492]

I have issues at 450 as well; sometimes it will boot, but often just resets the FSB back to 266... when it does boot, windows will freeze eventually. Then again, my ram is DDR667, so at 900, it's doing pretty well (LL ram, though). 440 FSB works great, though. I wish I'd bought a 6400...

 

[darkhorror]

any of you had any luck?

 

[bobsmith1492]

Nah... tried upping everything just a lil' on the volts side or dropping RAM timings to 6-?-?, but it didn't really help any. I probably just need faster RAM.
