Its not the core speed I'm after its using a divider to give me a faster memory frequency. If I can get my read/write/copy results over 9.2GB\s, i'll settle for that. Currently my memory is indeed in the yellow slots. Its really annoying how I get odd instability when I use dividers for my memory that take things above around 1090MHz. I know this memory can take it I've had it booting 1170MHz @ 2.2v.

Its the same for me even with this ddr3 mobo, some dividers just dont boot at certain speeds even though i know my mem can handle it, Some of the speeds are even below stock frequency

Thats not quite the same problem as I have. Your problem is related to your PL setting, try using PL9

I don't think that he is really "wrong" since with my settings the way that they are now I'm sitting at 4:5 stable but if I set my divider to 1:1 with eveything else the same my board won't even post. It could just be my nbGTL but I never really looked into it. Might also be the strap like I said I'm not sure. This board can be funky certain dividers at different clock speeds.

 

[ace80]

Ok maybe its not quite the same but similar. Oh and i forgot to mention that it does depend on the fsb frequency aswell.
PL settings don't change things either, tried that before. I usually leave it at 9 anyway unless i'm shooting for high oc's. Currently running 9 @ 4.4ghz

I still haven't tried this new 2105 bios yet, maybe tomorrow.

 

[Ketxxx]

Just noticed your using a Q3, things may be different, but for the rest of the P5Q boards PL setting does have a impact with different dividers. Some memory dividers just don't like any PL setting below 9, and depending on your system, you may need to use a PL higher than 9 to POST successfully.

Can I Join?

P5Q-Pro, 2002 BIOS

I'm on my third motherboard First one was DOA. Second one worked great. Got it all working on air. Put in my case, hooked up water cooling stuff, hit the button..... Did not boot! Wish me luck on this one.

EDIT: I see already joined. Just update my Name and bios version. Thanks

 

[Ketxxx]

That sucks.. be sure to clear the CMOS and remove the battery prior to doing anything else.

I never knew that, thanks. Thats good to know.

Happy camper here. I got it to boot and idle at 4.0 GHz, 445 FSB all on the stock cooler. Many thanks to Ketxxx, Tigger, and all the others I gleaned insight from.

I'm going to put it back to 3.6 @ 400, stick it in my case, hook up all the hoses,blocks, rads, fans, etc, carefully check for leaks, make the sign of the cross, draw a pentagram around the case, hang wolfsbane and garlic from the door, sacrifice a lamb, mutter curses under my breath, and hit the power switch.

Hope to get to a stable 450 FSB for starters.

Thanks again everyone!

So, your not very supersticious then are you? :

Not really. Actually I'm disgustingly a rational being. I wss just hedging my bets,....and trying to be funny.

I've built, repaired, and otherwise fixed thousands of PC's in my life. (It's what I do for Ducats.) When it comes to my own PC's, however, it rarely goes smoothly. This build has really been like a Shakespearean farce!

Oh well, such is life. This board seems to be healthy and I feel lucky.

OK Guy's, i need your help. I'm running a P5Q Pro and E8400 on water. Using Gskill 1066 ram. Can someone give me a screenshot of their bios settings for a 4+Ghz stable overclock? I'm at 3.6Ghz/1.35v with only FSB adjustment so far. Thanks in advance.


Oh yea, now subscribed.

 

[Deleted member 24505]

i could but mines a E8600 so it wont help will it?

I was running an e8400 c0 on a P5Q D for a while but have gone with a quad since so I can't upload a SS but I can give you some specs on what I was using.

First of all which bios are you using and is that 1.35v with loadline enabled? I'm assuming no.

Anyways my e8400 wasn't the best clocker in the world so I needed around 1.4 vcc with loadline for 445x9. With that VCC I would set my VTT (FSB Term) to 1.38. I like to keep my VCC a little lower than my VCC under load. with that I used 0.64 ish cpuGTL. I also had my vNB set to 1.26v, you shouldn't need much more than that. I had my PLL at 1.56v. You should be able to pull off a 4:5 divider but if not just use a 5:6. I had my timings set to 5-5-5-15-55trfc-pl8. Hope that helps some. Good luck.

Buck, I have the same setup.

FSB: 445
DRAM Read training: Disabled
CPU Voltage: 1.425
FSB Term. Voltage: 1.3
DRAM Voltage: 2.1
NB voltage: 1.2
SB voltage: 1.1
Line Load Calibration: Enabled
CPU Spread Spectrum: Disabled
PCIE: Spread Spectrum: Disabled
**********
Advanced:
Disable everything

I'm just beginning to fool around. With better cooling and better memory, I hope to get 450 FSB and (hopefully) lower voltages.

You be able to get 3.8 GHz/420 FSB with just CPU voltage increases.

Excellent nastyhabits. I'll give it a go tonight. Thanks!

I wouldn't run 1.425v for 24/7 clocks on a E8400. :shadedshu

If you need that for 24/7 @ 4GHz I'd downclock until its stable @ 1.39v max for 24/7 as its much safer, water or no water.


My settings for 4GHz on the E8400 + P5Q Pro are:
FSB: 500
Multi: 8
CPU Voltage: 1.37v
FSB Term: 1.36
DRAM Voltage: 1.95 (FlexII's @ 1000mhz) or 2.15v (FlexII's @ 1200mhz)
NB V: 1.35 (4GB kit)
SB V: Auto
LLC: Enabled
CPU SS: Disabled
PCI-e SS: Disabled


These settings are 24 hour Prime stable and I have used them for months without issue.

My E8500 does far better with 1.22v BIOS for 3.8GHz...stock voltage.


Edit: Corsair dont make the Flex XLC line, NastyHabits, your SysSpecs is wrong.

 

[MoonPig]

And E8400 needs 1.425v to make 4GHz! Mine/Tiggs E8600 does it under 1.2v!

I know it's slightly higher, but thats a big difference!

 

[aCid888*]

E8600 are just better binned samples, less voltage needed because the die its self is better sillicone.

The E8400 doesnt need 1.425v for 4GHz unless its a C0 or been heavily abused by you/someone before you got it...E0's are so much better and pretty much the only one worth buying.

 

[FreedomEclipse]

Can someone suggest me some settings for a 4Ghz clock on a P5Q pro witha Q9550? I think i might take a shot at it.

 

[aCid888*]

Check the settings I posted, it may work for you as the Q9550s usually clock well.

Done, booted up and running solid with benchmarks. 24/7 folding and crunching should be a nice little torture test. Ram is running @ 1000mhz/5-5-5-12, so I got a little more room, right? Thanks for your help aCid!

 

[Deleted member 24505]

Great chip thx moonpig.4ghz at 1.2v socket temp 25c/core temps 34c great PA120.3 rad too

Shame about the iffy core temp sensors,i would love to know the true core temps with this PA120.3 rad.

 

[Ketxxx]

1.425v won't kill a 45nm chip, especially in a P5Q board. Remember the BIOS setting is never what you actually get. Even with LLC enabled 1.425v will be more like 1.4v which is only just over what intel recommend as a safe operating voltage.

FYI intel recommend a maximum of 1.36v.
