E6600 on P5B-deluxe - help with OC, please - Page 2

Ambient... I guess it should be around 25°C
System temperature at normal load 40°C
CPU: 32°C at normal load, both cores at 22-28°C
2 fans: 120mm intake front and 120mm out back, good airflow, however the 8800GTS really heats the place up (@54-60°C)
Using whatever thermal paste came with BigTyphoon

Tried the first one, but failed. No boot.

shows your RAM to be capable of 4-4-4-12-4 timings @ 800mhz...but it is currently set to 5-5-5-15-5.

So..in your BIOS, under the 'chipset' tab, set your RAM timings manually to the following.

4-4-4-12-4-25-9-9-9-9 @ 2.2v...if the cpu boots and posts , do some memory benchies in Windows. If all is well, try to lower the settings to :
4-4-4-12-4-20-8-9-9-9 @ 2.2v...then repeat. If all is well, try to lower the voltage to 2.15 and repeat.

^^^^Doing that will drastically increase your memory throughput speeds.

You might try it again, first with these:

4-4-4-12-4-30-9-9-9-9,
x-x-x-x-x-35-x-x-x-x,
x-x-x-x-x-35-10-10-10-10,
4-4-4-12-5-35-10-10-10-10.

..if you dont get any where on 2.2v..then try it with 2.3v for the DDR. The Team can handle it for sure...its coded into your EPP settings for your RAM...so....try the looser settings first...then add more voltage if you cant get them to 'stick'.

Ambient ~ 22C
120mm Intel CPU fan & heatsink
120mm exit fan
80mm Fan located at the front of the case (by the HD's)
Akasa exhaust blower (for sapphire x1950pro)

CoreTemp crashed my machine as soon as i ran it - will try Everest.

also according to cpu-z my RAM seems to be running at 499MHz (2:3) how do i change to 1:1 ?

Ok. I got the system working at 4-4-4-12-4-35-10-10-10-10.

However, I got another question. Since the memory is 400 MHz native and I've seen other people get their FSB over 400 MHz, I tried doing the same as well. Worked fine at the begining, but before I could run Orthos, the PC restarted itself and wouldn't boot.

I tried:
CPU: E6600@3,2GHz (400*8 @1,45V)
PCI sync: 33,33MHz, PCI-e freq.:100, DRAM: 800MHz, everything else on Auto (didin't know the right settings)
RAM: Cellshock PC6400 CL4 (DDR800 4-4-4-12@2,1V) <-- when I checked the label on the RAM, I saw it should operate at 2,1V and with these timings)
BIOS version: 1101

What settings should I set for FSB400 (or maybe 402 or so - read somewhere that going over 400 is more stable than staying at 400), what voltages,...

I know, I'm hoplesess, I'm sorry, but I don't want my PC broken

You might need to either loosen the ram timings once it goes above rated spec (FSB 400+), or up the NB/SB voltages.

RAM should be fine..if anything add another .5v to make up for the voltage drop on Windows..timings look good, but I would start them at 2.15-2.2v just to be safe. Mobo's droop on the voltages..even RAM.

Your voltage settings for ~400mhz need to be set manually or you risk blowing up the mobo! When left on 'auto' the voltages will scale up with the FSB...which is very bad, not to mention overkill and dangerous at the same time. Try this->
-------------------
FSB- 400mhz
cpu vcore- 1.38v
NB- 1.45v
SB- 1.6v
ICHv- 1.02v
PCIE-freq- 100mhz
DDRv- 2.15v
Spread spectrum - disabled 'off'

That should work fine...If you start going above 400mhz and notice stability issues..try adding voltage to the CPU, SB then NB. I have found that they typically 'hold up' your OC in that order and fashion above 400+mhz FSB.

BTW, I use the same settings as above for a 3.6ghz e6700.
