AMD 64 3700+ San Diego

post #1 of 8
Thread Starter 
Hello all, Herox here, and I'm new to these forums. I've done a bit of snooping on these forums today, and really can't get my overclock right on my 3700+ sandy CPU. I'm pushing for 2.8 on stock cooling, and right now I am at 2.6, but it seems sluggish.

You see, I don't understand the whole timings thing between the CPU and RAM. My system specs are in my signature, and I will share my BIOS settings with you here:

General CPU Settings:

CPU Speed: 2585 MHz (Everest Home says 2600 MHz)
Hyper Transport Frequency: 4x
Cool 'N' Quiet: Disabled

DRAM Configuration:

Memclock index value (MHz): 200 MHz
CAS# Latency (TCL): 2.5
TRAS: 7T
TRCD:3T
TRP:3T
TRC:11T
TRFC:13T
TRQT:5T
TWR:3T
1T/2T Memory Timing: 1T
S/W DRAM over 4G Remapping: Enabled
H/W DRAM over 4G Remapping: Enabled

JumperFree Configuration:

CPU Frequency: 235.0
PCI Express Clock: 100 MHz
DDR Voltage: Auto
CPU Multiplier: x11
CPU Voltage: 1.4125v
PCI Clock Synchronization Mode: Auto

Any help with the timings, etc. is needed!

I was also wondering why my computer loads my desktop slower now, maybe it has something to do with going from 400MHz memclock index value to 200MHz memclock index value...?

If anyone can understand my clutter of a post, feel free to help, as I am more than willing to cooperate with your efforts!

Thanks.

Hmmm, Vdim? Would that be my RAM...?

And my RAM's voltage is on Auto, so i'm not sure what it is on, what do you think I should put it on?

Also, could anyone provide me with what everything under DRAM Configuration from my first post SHOULD say so when I overclock to 2.8, I know what to input.

Thanks!

In your bios

Set your Dram to a divider 166/333
Set your HTT to x4
Set you multiplier to it's Max x11
Set your FSB to 210, Reboot... check for stability
Next try 220, Reboot... check for stability
Next 230, Reboot... check for stability
Next 235, Reboot... check for stability
Next 240, Reboot... check for stability
Next 245, Reboot... check for stability
Finally try 250, Reboot... check for stability

250 should be your max at HTTx4, If you start to go over 250 lower HTT to x3
If you go over 260 lower your dram divder to 133/266

If you find you have unstability up your V.core in very small increaments till it's stable. Keep your eye on your temps after rasing the V.core, Dont go above 50c under load.

Have fun and post back if you run into a problem.

Vdimm is the ram and vcore is the cpu. I can't see that be the loading issue.
Put it back to stock and see if it still does it??

That's the other thing that I am not sure I understand too well.

What exactly is a Dram Divider and How do I set it?

Thanks!

"DRAM Configuration:

CAS# Latency (TCL): 2.5
TRAS: 7T
TRCD:3T
TRP:3T
TRC:11T
TRFC:13T
TRQT:5T
TWR:3T
1T/2T Memory Timing: 1T
S/W DRAM over 4G Remapping: Enabled
H/W DRAM over 4G Remapping: Enabled"

The bolden setting should have other options, including 166, 133 etc...

You could also try Clockgen to get a rough guess without restarting many times.

:do this:

Set your Dram to a divider 133/150/166mhz whatever is more stable
Set your HTT to x3
Set you multiplier to it's Max x11
Set your FSB to 210, Reboot... check for stability
Next try 220, Reboot... check for stability
Next 230, Reboot... check for stability
Next 235, Reboot... check for stability
Next 240, Reboot... check for stability
Next 245, Reboot... check for stability
Next 250, Reboot... check for stability
Then do 255, Reboot.....chech for stabilty.....into which you should be at 2805mhz


BTW, ClockGen is evil......not a good OCer, always do it in the BIOS......
