Asus P5Q Pro, E8500, DDR2-800 (PC2-6400) - Trying to overclock... n00b! lol - Page 2

post #11 of 34
Hi Static, it looks like I have the same setup as you.

I've got my E8500 up to 4.4GHz currently on 2x2GB of OCZ PC2-6400, so you should be able to get good results as well. thumb.gif

First of all, leave the PCIE frequency at 100. I've seen quite a few OC guides say you can bump this up a little bit, for me, whenever its above 100 my P5Q Pro won't boot.

Secondly, I'd just pull the Wintec RAMs out. In the past, I tried running 2x2GB OCZ PC2-6400 and 2x@GB Mushkin PC2-8500. Both ran up to 466 FSB on their own, but together I could not get them stable for anything higher than 333 MHz.

Also, this board simply isn't as stable with four sticks of RAM. I had 4x2GB of Corsairs (all matched sticks) running up to 450MHz, but I couldn't get any higher.

The very first time I overclocked this board, all I changed was putting 400 for the FSB freq and everything else on auto, and it worked fine. Since then I've delved a little deeper into the settings. wink.gif

Here are my current settings:

CPU ratio: 9.5
FSB: 466
PCIE: 100
FSB Strap NB: AUTO
DRAM: AUTO
DRAM Freq: AUTO
DRAM Timing: Set to 5-5-5-15 (or per your RAM specifications)
DRAM STATIC READ CONTROL = DISABLED
DRAM READ TRAINING = DISABLED
OC charger=ENABLED
AI Transaction booster=AUTO

CPU Voltage: 1.44 (generally don't want to go over 1.4, 1.45 tops
CPU PLL Volt: 1.50
FSB Term Volt: 1.3 (don't exceed 1.4)
NB Volt: 1.3 (don't exceed 1.4)
SB Volt: AUTO
DRAM Volt: 2.0 (or something close to your RAM specs, you shouldn't have to go over that)
PCIE/SATA Volt: AUTO

CPU GTL: AUTO
Load line calibration: ENABLED
CPU Spread: DISABLED
PCIE spread: DISABLED
CPU Skew: AUTO
NB Clock skew: AUTO

At least I think that's what its at. Its something similar at least. rolleyes.gif I would shut down and boot into BIOS for you and check, but I have my computer going for a Folding@Home competition currently. redface.gif

EDIT: And I'm currently seeing an FSB wall around 475MHz on this board, so its generally pretty good for overclocking! smile.gif

And looking at your Wintec sticks, the specifications seem close enough to the OCZ ones that they should work alright, at least up to 400MHz. You'll just need to increase both NB voltage and FSB voltage a little bit.

Ratio: auto
FSB: 423
CPU Voltage: 1.35
ram voltage 1.9

i pulled the wintec and its wintec AMPX.. does that make any difference?

it says its running @ 4.02 but chrome crashes constantly.. im going to back the FSB down a bit

thanks Jetpack!

what if i want to stop at 4. ghz?

i set the ratio to 9
and the fsb to 420 and im running at 3.8 seems fine at the moment...

so can i use those setting but drop the FSB to.. 440 or so?

its booting now, but i got a CPU over temperature warning on boot?

4.25ghz......



edit:

yeah - just shut itself down lol
went back to
ratio: 9
fsb: 420
cpu volt: 1.35
everything else auto

3.8ghz

If its running fine at 3.8 currently, try increasing FSB to 440 without changing anything else.

If it doesn't boot, then increase CPU voltage a little bit. No sense putting in more voltage than you need. I think my CPU needs about 1.38V to go to 4.1GHz, if I recall correctly.

And looking around online, it looks like the AMPx line of RAM is pretty solid. I would definitely put it back in and trying playing with some settings to see if it will work with all four.

The problem with un-matched sticks of DDR2 though is that the P5Q series of motherboards (and possibly other socket 775 motherboards) are rather picky when it comes to RAM, especially when its being clocked over 400 MHz.

Here's a post of how I got 4x2GB sticks to run stable. The important step was to make a change in the 2nd Information under the RAM timings:

I also set the timings to 5-5-5-15, and changed Read to Read Delay (S) and (D) to 5 and 7, respectively, in the "2nd Information" ram timings, based on a post made by turrican9.

Hmm, I've never seen the CPU over temperature warning before. What CPU cooler are you using? What are your temps at 3.8 GHz?

dude.. not good!

i am using an ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler (arctic silver thermal paste)
case has 2 120mm fans, one pulling in air in the front, 1 pushing out the back (+ the psu fan)

at 3.8 - no load it was mid 60's... running prime95 it was 98!.. im going to say thats not good?

dropped everything back to default, temp is mid 40's
running prime on stock settings its sitting at 58


after a little while.. temp is sitting at 67.

i think i need to re-seat my cooler

edit again:
ok.. it seems i had quite a bit of dust between the fan and the cooler lol
its now snowing in my office. wow! *cough* *cough* ok.. there was a LOT of dust!

now, stock - full stress for 15 mins.. max was 57

so, now i can try again for the 3.8ghz (tomorrow - not time left to play today)

Thanks all!

Yes, that's much too high. Make sure you get all the dust cleaned out of there and give it another go. smile.gif

I haven't heard great things about that cooler, but it should be good enough to get to 4GHz. thinking.gif

how do i know how low i can go with the CPU Voltage?

Ratio: 9
FSB: 420
CPUv: 1.35
3.79Ghz
89°C during prime95 large fft



Ratio: 9
FSB: 420
CPUv: 1.325
3.80Ghz
79°C <-obviously much better, but i would like to get a little lower


Ratio: 9
FSB: 420
CPUv: 1.30
3.80Ghz

heres a question:
in SPEEDFAN it says:
CPU: 78°C
and then lower it says it again

in CPUID HW Monitor
there is a CPUTIN: 78°C

but lower is a CPU Core#0: 73°C
CPU Core#1: 71°C

Which one is the reading i should be looking at? the 2 original reads (89/79 above) were from the CPU Core#0

Thanks!



EDIT:
Ratio: 9
FSB: 425
CPUv: 1.2875
3.84Ghz
CPUTIN: 78°C Core0/1: 73°C/71°C <-after 10 mins of Large FFT's

UPDATE after 1 hour... Rounding error (P95 - Blend).
so i should up the voltage a little.. correct?
Ratio: 9
FSB: 425
CPUv: 1.3000
3.84Ghz
CPUTIN: 74°C Core0/1: 68°C/66°C <- after 10 mins on p95 blend

where is the stress.txt file?

i know i am just rambling, but im kinda taking notes for myself (and if anyone wants to comment... smile.gif )

You'll want to go with as low a voltage that is Prime95 stable. thumb.gif

I like to run blend for the CPU stability test, as it stress both the FSB and CPU, and you'll want to run it for at least 8 hours straight if you can to confirm complete stability.

And you're correct, just bump up the CPU voltage a notch or two each time it fails.

Also, the stress.txt file should be located in the same directory as the Prime95 exe, but it just contains some general information on stability, and nothing specific to why it failed in that particular instance.

And I think that CPUTIN is a different sensor than the ones that are built into the chip itself (which are reporting the Core 0/Core 1 temps), but I'm not sure which one to believe more. For me, the Core Temp program and HWMonitor both give the same values. That is, Core 0, Core 1 average to what HWMonitor is giving me.

Lastly, did you try putting the Wintec RAM back in? And what's your vNB and vFSB at currently?
