Hey overclockers

I hv a problem with my overclocking. Currently using P5Q dlx to overclock Q9550 to 3.5ghz. Using 4gb DDR2 1066 (Crucial ballistix)

Heres my setting :-

Vcore = 1.25v
Vtt = 1.10v
Dram voltage = 2.1

Now, i stress it on prime95 n OCCT...it was stable but when i restart, the machine runs but no display and worst of all the lights on the RAM doesnt light anymore.

Please help thx

Cmos reset almost 3 times. Cant figure why my CPU stable but RAM isnt running at all after restart

this is my new setting and it works perfectly after 8hrs of prime95 and 4 hrs of OCCT

FSB : 380
Timing : 5-5-5-18-3-40-6-3
Vcore : 1.3
Dram volt : 2.2
Vtt : 1.20

now, when i change the fsb to 412 and ram timing to 5-5-5-18-3-20-6-3. It didnt work anymore. The rest of the settings i remained the same. Please advise thx

hey overclockers

I need ur guys help..im currently at 475fsb which is 4.03ghz on Q9550 e0 and rite now while typing this, im running small fft on prime95 and the temp for all 4 cores r 80,76,75,79....i need to know if its normal temp after oc..normal idling would be around 50-55

guys,

I need ur help abit. Im running Prime95 on small FFT for 24hrs didnt come out any error but when running on large FFT, it comes out error. What opinions do u guys have abt this

This is my bios setup for Q9550 E0 OC 4.0ghz on P5Q DLX

FSB - 475
Vcore - 1.46825
VTT - 1.3
PLL - Auto
NB and SB - Auto

Help me out thx alot.

Needed help. To those who are using Q9550 E0, whats ur Vcore when OC to 4ghz ? Does it applies the same to all mobo ?

Im getting curious as to getting 480fsb which is 4.1ghz im already using 1.5v when most forumers i heard from r using 1.5v when they reach 500fsb. Mind giving a few tips. Thx

My current settings
FSB - 475 (4.03ghz)
Vcore - 1.4625
VTT - 1.26
CPU GTL - 0.65 on both
NB and SB volt both are on auto.
