Yes that's what I followed. I'm going to start the process again...

some memory modules support 8 beat burst length and is in the spec.rebelranger said:On Post #490 It says Burst Length =4 beats ( 8 beats if your Ram supports it).
How can you find this out?
rebelranger said:Ok i'm finally up and running and really stable. Screenshots coming.
Did all the patches...System is incredibly fast.
Tweaking is a little strange to me. The memory especially, I am using Bios 2.10...
ochungry said:some memory modules support 8 beat burst length and is in the spec.
I tried to find it in your mem spec but could'nt. So, go ahead just use 4 beat.
how is overclocking? what speed do you have it now.
Try 250x10 to give you 1:1 ratio.
If have done the vdimm yet, those rams should only need 2.7v @ DDR 450, same timings (3-4-4-8, 1T). So you might want to use 166/333 memory speed/divider. That will put your speed to 270x10=2.7ghz and memory @ 225mhz(DDR450).

RollingThunder said:REb,
240-245 MHz was about the peak I could reach without volt mods, you may be there too especially with your stock vdimm.
All the voltmods for this board (Asrock dual SataII) are in the opening post of voltmod thread.rebelranger said:Can someone point me to a link with a photo of the completed mods or post a photo?
Oh no problem. just review the mods and if have any Q? throw it at us.rebelranger said:Yep I like your vcore mod...
Thats the easy one. But the vdimm is not sinking in..thats why I wanted to see it in final. I have all but the wick and want to do this tomorrow night... I'll review the post again and see if it sinks in...
Thanks for your patience with me on this...

If you look at the screenshot of my homemade VR you will see how I am currently using the vdimm. The VR I mentioned w/ 1-2k trimmer/VR, will give you lots of vdimm voltage variations. The OCW's and TechPowerUP's will put you into fixed range. My method is simpler and easier I think. less messy too. all you do is solder 2 wires to (one each end of ) resistor #2 and bring the wires outside of the case and play w/ vdimm. I also have soldered a wire to vdimm read and check vdimm w/ voltmeter outside of the case.

Vdimm read
Some basics on VR/potentiometers
My homemade VR (Variable resistot)
Radioshack's 10K VR. max is 10k that will give you: (10*1.2)/(10+1.2)=1071ohm=no change
5K will give you: (5*1.2)/(5+1.2)= 967 ohm=little increase in vdimm voltage. maybe ~2.75v
2k vr @ max will give you : (2*1.2)/(2+1.2)=750ohm=2.82v vdimm
1k max Vr= (1*1.2)/(1+1.2)=545ohm= 2.88-2.90v vdimm.
That's why I said use a 2k or 1K Vr (blue rectangulare)from radishack.
It has 15 turns. max=2K=2.82, 1/2 way(7-8 turns)=2.9v, and is near 200ohm will give you about 3volts vdimm.
OCW vcore mod corresponding vcore table
Hope all clear. any Q, dont hesitate to ask.
good luck
EDIT: Just remember to use soft/flexible wire such as stripping IDE string. Solid wire will break off the resistor, because it's stiff.
Yes I posted it in AMD cpu section.rebelranger said:Did you guys see this articel?
Im thinking of doing the AM2 Platform..ochungry said:Yes I posted it in AMD cpu section.
Your next opteron build should be AM2 platform. Tha's what I am planning.
I am hoping that a 2.ghz can overclock to 2.8ghz and good to go for couple of years at least.
Great. which version of vcore did you do? (VID3, or VID4, mine or OCW's)?rebelranger said:Im thinking of doing the AM2 Platform..
Which board are you considering..?
I am thinking DFI...
I did the vcore mod with no problem..
Ill play with this a while then tomorrow tackle the vdimm..
