board model: ASUS P5Q - Pro (p45 of course and ICH10)
BIOS: 1406 (dated 10/02/08) its a little out of date

It is born!
Almost 2.5M points in folding and still counting thankyou!

Need to be pointed in the right direction here.. at 3.82Ghz, ram at 1123, ram won't go much higher, and I'll have to change things to get 4. I'm also wondering if I should decrease vtt on this puppy, not sure about all these settings yet, screenshot from a very bad camera alert! :

I did up vcore a bit.... 1.320v, nb at 1.22v, so far stable at 3.82, warhead runs fast at 1920x1200, all enthusiast, 2xaa, lag zero! Now for some gta4!

[johnspack]

Never mind, orthos stable, next step:



at this voltage, I don't see the point in 4.....
I want to play with gtl settings now, and see if I can reduce vcore.

[johnspack]

Discovered something interesting, I need to set SB voltage at 1.20v from default of 1.10 in order to run my gtx280 at 1512 shaders. If I don't, I get garbled colours all over the screen like the card's ram is bad. Soon as I do, games run for hours no problem. Didn't think sb should have anything to do with my single pci-e card on this mobo... (I'm using the primary)
This should show I'm using full 16x pci-e2:

Is it normal to have to run the sb at higher voltage to oc your vid card? I thought the nb handled the primary video card? Sorry, learning stuff here....

Well you should play with your VTT before you touch your GTLs since auto tends to overvolt and the GTLs are based off of your VTT. Secondly it sounds like the southbridge at 1.1 may have been causing some crosstalk with the shaders running at 1512 for some reason but thats just a guess. I would be willing to bet setting your pci-e frequency to 101 would also have done the trick.

[johnspack]

Ah, didn't know that about vtt, thought it was other way around, if I change it, I have to change gtls too, I have to go back and read all that stuff again.. I may see if messing with that will help me maybe to get 3.9 stable at a vcore I can stand. I prefer to keep at 1.36v for 24/7, it's being rock solid at 3.8 with 1.32v. Oh, and I did have pci-e set to 102, so it did need the sb bump. Also I hadn't disabled pci-e spread spectrum, not sure if it needs that off or not....

I'll ask here too, the mosfets above the CPU socket on a p5q3 are they activated?

As they're cold to touch even when everything in my system is underload, if they've not activated is there anyway to do so?

I've already got a mosfet cooler for when/if I can/

[johnspack]

Interesting, I just felt all 3 of my mosfet heatsink/heatpipe rads, and they are just slightly warm to the touch, so I guess all 16 phases are running.... haven't checked under load yet, but I bet they get fairly warm.

Edit: 3.9 is looking stable with vtt at 1.14v and cpu at 1.336v, probably will need more tweaking, but thanks for the tip Baba!

You may want to read through the first few pages of this thread there is some good info on the different schools of thought on setting your GTLs and VTT that are explained much better than I possibly can.

[johnspack]

Yep, that's the thread I need to go back and read! I've read it many times now, still trying to get it... but 3.9 is rock solid gaming stable now, crysis has never run so fast!


I may see if I can get 4 stable at 1.36v, but I kind of doubt it....
Edit: 3dmark06 has gone from just over 12k on my athlon, to 17.7k right now, bet I can do better!
Edit2: I believe this is my max 24/7 oc for this CO. 1.336v is really nice. I believe gtl settings will come into play when I get a nice quad.....

Need help Overclocking my e2140 with P5Q Deluxe.

I hit a wall at 360 FSB. Just under 2.9Ghz.
was hoping I would be able to get a higher Clock using this board.

Loving it thus far anyway.

I am farely new to overclocking so any advice would be greatly appreciated.
Any ideas on what I can try?

I am using Kets's modded P5Q Deluxe Bios. Runs great just that The FSB wall still exists.

I'v found that I get the most stable clock when I leave most on AUTO and just bump CPU Voltage up to 1.45.

[johnspack]

First thing I would try is pull one stick of ram and just have 2 sticks in proper dual-channel mode(using the 2 yellow slots) and see if you get better. I've checked reviews ect and this chip has gone to 3.2ghz at 400fsb on a p35 motherboard! So should be easy on your motherboard. Also for high fsb, it helps to up NB voltage. I believe mines at 1.26v right now, might be lower I'll have to check next reboot. So up the NB voltage, pull one stick of ram, and try 400. Getting 1066mhz ram might also be a good idea. Two sticks of 1066 4GB kit ram would be best.

[miko2323]

Thanks for the tips... Will give those a try later tonight.

But I think it's time I got rid of the old e2140. It is clearly a bottleneck in my current setup.
I see an immediate increase in my Framerates after the overclock.
My chip at default speeds of 1.6Ghz just can't hack games like Crysis and Far Cry2 at 1920x1080 Full Detail.

e2140 at my current 2.9Ghz gives me a minimum Framerate of 26FPS and an average of 36 - 40 FPS. Which is cool as it is just over the playable MINIMUM.

But yeah long story short. Could any1 recommend a decent budget C2D or Quad Core.
E7600 or Q8400 maybe? Would like to see what this board can really do with just air cooling.

Discovered a stability trick, reduce your .67x gtl to .645x, but not lower. Good for e8400 co stepping cpus. Good for 3.92 24/7. Weird but true....

It all depends on your VTT. I found around .645 to be best for my e8400 c0 at 425x9 personally. Keep in mind that a difference of half a percent can mean the difference between 1 to 2 hour prime small fft stable and 24/7 stable.

[johnspack]

Gotcha! I've also learned how stable this platform is, gawd it rocks! Yes, .645 gtl works best for my settings. Just wish I hadn't had to deal with a dying gtx280 in the process. I'm going to crank it back up, and make my 9800gtx scream for mercy!

191.07 has another victim. Funny thing is that I sold a GTX260 a little over a year ago and the buyer just contacted me claiming that 260 met the same fate. I'm glad that I'm running an HR-03.

I am going to be ding a fresh install of Window 7 at some point soon and was wondering which chipset drivers that you guys are using? Are you just using the default Windows 7 drivers or updating to the ones on the Asus website?

Thanks

P5QC Will post my BIOS as soon as uTorrent is stopped....

Thanks All

[johnspack]

I use the asus site drivers for my deluxe. Stable as hell! Now a question of my own, if you're doing a high cpu oc, and using gtl refs to stabilize and lower vcore ect, if you unbalance the gtls, would it cause problems for say communication with the video card? I was using .630+ .640 and got what looked like a video card crash(splotchy coloured screen), so I went .635+ .650 and everything appears stable now. I'm not sure if I'm just not cursed by reference Palit made cards or not..... Edit: okay that was dumb even for me... could a destabilized cpu cause video problems... probably yes. I'll work on it....

[jlewis02]

Can I join?
Maximus II Formula
Bios 2202 I think its the new one.


I run it at 3.8ghz 24/7 tho.

[johnspack]

Turns out my video card was dying, so I can go back to tweaking my c0! An unstable video card does not help ocing.... I've been keeping it around 3.9ghz because of these problems, but with my rock solid 9800gtx, I could probably game at 4+ghz. I was playing with gtl settings until my stupid gtx280 went whacky and threw off my train of concentration. Now I'll correct those again and hopefully pull 4ghz 24/7 off next... tweaked, my 9800gtx is pulling off close to the same fps as my 280, must have been sick....
Edit: and my vcore is down to 1.328v, and I should be able to lower yet...

[johnspack]

Well I'm back up to 3.93. I'll try an orthos stable 4 tomorrow, but still not sure if this chip will do it at 1.36v. If it takes 1.4v just for 700mhz, and I'm at 1.32v right now, not worth it.... Could try a bit more gtl balancing, at 630/645 right now, very stable.
