Lanparty Ultra-d and 3500+ - Where next?

post #1 of 49
Thread Starter 
Hey guys I'd really really appreciate it if you could help me with a little frustration please.

I have as you can see from sig spec AMD64 3500 oc'd stably to 2.53 ghz on a DFI Lanparty UT Ultra-d NF4 mobo.

Before starting to overclock I did a lot of reading on this forum and dfistreet to find out how you oc A64. I have oc'd several athlons before but this is my first 64 rig. I thought I had got my head around all the maths and ranges and so set about upping my speed. Gradually I got it to 2.53 ghz stably. I had to drop my ram speed as suggested but on the whole it is working fine with the following settings in my genie bios.

FSB BUS FREQ : 230
LDT/FSB RATIO : AUTO
LDT BUS TRANSFER WIDTH : (down arrow)16 (up arrow) 16
CPU/FSB FREQ RATIO : x 11.0
PCI-E FREQ : 100mhz

(I have read about the LDT/FSB ratio and differing opinions on where to have it, 3x, 4x or auto, as lots of people have reported no issued with it at auto I leave it there and have had no issues until the one I will come to at end of post.)

DRAM CONFIG

DRAM FREQ SET 150 (3/04)
Command per Clk : auto
cas lat : auto
ras# to cas# delay : auto
min ras active : auto
row precharge : auto
row cycle : 07 bus clocks
row refresh : auto
row to row : 02 clocks
write recovery : 03
write to read : 02
read to write : 03
refresh period : 3120
write cas latency auto


Right, with all the above settings I run stably, if i put dram at 166 i get slowdown, not dramatic but noticeable so I stay at 150 and have never touched the timings.

Now here is the frustrating part. If I up my fsb bus frequency by 1 to 231 my pc goes nuts!!! It takes 3 times as long to load windows and when it does just as you get the welcome music it hangs and the music stutters.

I dont quite understand why this is happening and it will happen if I change LDT/FSB to x 3 or x 4. With my current settings if i change ldt/fsb to x3 then I load and run slowly, at x4 I am same as at auto.

What am i missing? What should I be doing that I'm not? My max load temp with above settings is 38 celsius so its not heat thats the problem, the problem must be me lol but I'm miffed I can find what I'm doing wrong.

Any help is greatly appreciated.

First thing I'd do is set the DRAM settings to "Auto". Those settings come as default, but often the Row Cycle, in particular, at 7 is too tight and can cause instability.

Then drop the ram onto a very low divider Eg. Memclock 100 and then just work on the CPU speed. When you have found the max here move onto increasing the Ram speed/timings.

You'll need to raise the vcore as well when raising the CPU speed. Just keep an eye on your temps when doing this.

My dram and my divider are the same setting, if i set it to auto I cannot change the divider. Sorry to be a bit dumb but could you clarify which settings to change

Sorry, mis-typed it's Row Cycle that's at 7. Yes, set to auto for now and then work on them later.

No worries, ok, so just to clarify before I go to bios, all the timings except the divider should be set to auto, every single one? Then the divider dram set to lowest at 100mhz and whatever ratio it sets itself at.

Thats all these
Command per Clk : auto
cas lat : auto
ras# to cas# delay : auto
min ras active : auto
row precharge : auto
row cycle : 07 bus clocks
row refresh : auto
row to row : 02 clocks
write recovery : 03
write to read : 02
read to write : 03
write cas latency auto

to auto?

then play with my cpu speeds, how much should i increase the voltage by and what is the cpu voltage called in the bios?

Yes, all those in the list set to auto. There's an option called VID with settings upto and including 1.55v. Set to 1.4v to start with and then move up 0.05v when you become unstable upto 1.55v. Keep an eye on your temps everytime you up the voltage, keep them around 50°C at load and you'll be fine.

There's also a VID special % setting if you want more than 1.55v. Eg. the first setting is 104% of the VID setting. Wouldn't recommend more than 1.65v at a push though and probably best to keep to 1.55v initially.
