Thx for the reply...i will try it but if i up the voltage on dram (which i did tried earlier) & also increasing a slight increment on ram freq, it just runs 100% fan full speed with no post
Added on August 5, 2009, 11:06 pmHey guys,
I need to ask for ur experiences. I currently did some OC testing and below r the results
FSB : 400
Multiplexer : 8.5
fsb strap : 400
Dram freq : auto
Vcore : 1.31
PLL : 1.54
Vtt : 1.24
Nb volt : 1.22
Dram voltage : Auto
Result : No post and fan keeps running 100%
Second testing with slight changes on above settings
Fsb : 400
Multiplexer : 8.5
Fsb Strap : 400
Dram freq : auto
Vcore : auto
pll : auto
vtt : auto
nb volt : auto
Dram volt : auto
Result : Able to run and insert windows without a problem
Whats causing the problem?
as for my settings for q9550 @ 3.4ghz..(just reference ah. dun follow exactly cuz diff mobo diff settings for stability)Added on August 5, 2009, 11:06 pmHey guys,

400mhz x 8.5 = 3.40ghz
cpu vcore 1.25
den the other Voltages, i din set auto.. i key in the defaults values instead..
den mch i bump up 0.6v
as for vdimm(vram).. 2.04v.. timing 5-5-5-15..
i think q9550 dun need alot changes to make it to 3.4ghz.. im pretty sure at stock voltage 1.25v.. it can run. i saw ppl using even lower vcore n still stable..
i think important is ur mobo mch and vdimm.. check ur sticker label for ram wats the voltages.. normally if auto, the bios set the ram voltage pretty low..
i think in bios ram voltage they usually set to 1.8v for auto.. its way below wat is recommended by the ram manufacturer.. like i say earlier.. check ram sticker for default voltage to run..
