Its a nice one on the NB but still sucks. If i have to put the 12th cooler in the chasis i give up instead and go with stock speed wink.gif
Im not convinenced of the NB, it might be something else but honestly i just got bored with this oc project after this long unsuccessful attempt.

Looks like people been overclocking with that board.

the P5Q Pro Turbo is known to be one of the most accurate asus boards for 775 chipset in relation to voltage. It's also a good overclocker. It should be, at least, as good as mine, and mine , the P5QC can take my X5460 to 4,3ghz almost stable and it will run 4,5ghz at 1,45v. So, i think you are missing something very "big", because that board and that CPU are more than capable of doing way over 4ghz.

post some bios screenshots of the AI tunning, maybe we can help you.

I also used that video to ilustrate myself a few months ago. I gave up the moment i saw no LLC , and almost every option on Auto. Honestly, that guy knew very little of overclocking. In fact, his computer crashed once in the video.

You said you were stable at 4,6 1,47v. You didn't mention the test passed. Would be very nice to know which one and the temps you got (if you could post an screenshot including HWmonitor would be awesome).

Well, LGA 775 is tricky when it comes to OC.
There are many things that need to be set for stable high OC.

Basic stuff is easy :
Vcore, FSB, DRAM Frequency/Timings/Voltage and VTT.
Set those right and with right board, you can do pretty good.

It's the Advanced stuff like Straps, GTL's, "RAM Boosters" (ie. Perfromance Levels mostly), that give most people hard time when OC'ing to max.

Example :
I was shocked that this guys didn't play with them at all, and he's got a phase cooling on that E8500 - https://www.youtube.com/watch?v=f5tI3vNCu9g (interesting part starts @3:38:30).

a P5Q Pro Turbo is in fact easier to deal with than mine, since P5QC and P5KC , and almost all 775 ddr3 boards are known for not being stable at over 1333mhz. Using DDR2 , much developped , is easier.

For example, i have a ddr3 kingston HyperX blue, KHX1600c9d3b1k2/8gx rated at 1600mhz 9,9,9,24 1,65v. My board will not post at 1600 not even at stock settings. Not even introducing manually the settings.

I've done so many tries that i would need a hole hour to try explain the issue, but i've played with timings (i know for a fact that my ram will do 2133mhz at 1,70v 10,11,11,30 because those timings worked on my P9x79 deluxe paired with an e5 1650 at 4,9ghz). But this exact ram will not post at anything above 1350mhz on the memory in my P5QC no matter what i do.

i disabled memory training, tried auto, tried increasing NB voltage, tried going to 1,8v vram, tried fsb strap (weird as it may seem, some ram dividers do not work). For example, i cannot post at strap 400mhz and ddr3 950. But i will post at 1266mhz and 1359). does that make sense??
i tried OC mem mode, tried almost all straps and mem dividers, tried the clock twister, tried AI transaction booster at 1, 5, 9, 10, 15, 20, and 30. No way.

it seems to me that my Xeon cannot handle more that 1333mhz on the memory. It seems that. i haven't seen any X5460 working with ddr3 on my board so don't know where is the issue.

The best asus board with ddr3 outthere is the P5Q3 Deluxe Wifi. it allows ddr3 for more than 2.000mhz. indeed, i tried my ddr3 8 gigs savage 2400mhz on my P5QC. No post. not even reseting the bios. Then i remembered that this board does not recognize modules of over 4gigs.

Anyway, i'm happy with my board, not as happy as i would like to, but anyway it's very nice.

Well, both P5K64 WS http://valid.x86.fr/i8y1ch (8GB) (16GB : LINK) and Rampage Extreme http://valid.x86.fr/mcw0h8 (8GB) http://valid.x86.fr/jqkk9z (16GB), are fine with ~1600MHz on memory.

So... I guess I'm lucky... or I just know what memory to pick smile.gif
Either that, or DDR2+DDR3 boards are crappy in DDR3 OC.

I think there are exactly "0" LGA 775 boards, that can work with 8GB DDR3 modules.

PS. As was mentioned earlier, I always actively cool NB heatsink when OC'ing.

+ As was mentioned earlier, I always actively cool NB heatsink when OC'ing.

nice!! but a few things.

1º well, X48 boards, specially yours (in case it's yours), deal very well with ddr3 memory. So no surprise there as x48 was the flagship of the company in the enthusiast platform.

2º it surprised me that P5K64. It can be a matter of compatibility with ram, but you are ignoring one important thing: you are using a dual core Pentium extreme edition not a quad in that board P5K64, so if you put a xeon on that (in case it's possible , i don't know that), maybe the results could vary.
I bought this memory almost 5 years ago. I did not "choose" as you stated. I simply bought them. I did not care about overclocking at that moment. If i had cared, i would have asked for best compatible Ram outthere. i said and i confirm that almost all 775 ddr3 mobos are unstable over 1333mhz. That doesn't mean you cannot post over that. let's be accurate on that.
It's a bit "unfair" to say that if your board works, it's that all work. see the internet, many many many posts talking about ddr3 + 775 mobos problems. Pretty sure that are more problems than "just fine" cases like yours.

3º you are right, there is no 8gb 775 motherboards compatibility.

4º afaik, my board will handle 1,3v on the NB without any active cooling. as my ram will not post at anything over ,1360mhz, i simply don't need to actively cool the NB chipset.

Edit: your A-data ram in the P5K64 WS is not in the compatibility list supplied by Asus for that mobo

Best OC motherboard I ever had from ASUS was ASUS Commando (very rare nowadays)... Chipset P965 and took everything I've thrown at her... P5K Premium and P5E Deluxe were very good as well... For Xeons I think the best choice is a P45 chip, more stable under stress and delivers more power to CPU than P35 chips... P35 are lack of power phase to deliver good and stable Quad Core OC...

Ad. 2. Here's QX9770 ("Xeon - like") on P5K64 WS - http://valid.x86.fr/mcw0h8

As for DDR3 boards - True, but I think best compatibility lies within one type of memory support MB's.

PS. Compatibility lists are for beginners.
I'm not a beginner wink.gif

As for DDR3 socket 775 boards, lets not forget that the 790i nvidia chipset boards handle 16Gb with jiggery/pokery, and 8Gb solid. Speeds over 1333. Here's an example in this post. http://www.overclock.net/t/1547699/790i-ultra-nvidia-chipset-still-rockin-in-2015-2016-2017-will-it-ever-die/300#post_25814249 Edit: No jiggery needed for this fella's ram! wink.gif
