I am also curious as how much of a PITA is water cooling?
Thanks for your help
I believe what's important is in how one feels about it at the outset. PITA is relative in this regard. I have spent quite a few hours reading about watercooling and I enjoy customizing and building the various setups. In this regard it is more of a hobby which is what this forum is all about. It is not hard to put together a good watercooling setup and you can make it as complex as you want. There are good sticky reads in the liquid cooling section of the forum. If you have specific questions don't hesitate to ask. People on this forum are more than willing to help.Quote:

Hi Razmatazz,
Thanks for the input. I have read that the PLL is a variable that manipulates the SB and that it should not be adjusted??? Also when you test setting do you go through all possible comination adjusting one varible at a time? I am running at 3.2gHz right now with 400 FSB Ram 400, 1600 with all on auto. So from here I guess its FSB 425, is there a ratio for vFSB to vNB that one can use or do you simple raise one then adjust the other until you are stable.
Yep, you got that right. Adjust one setting at a time and retest is the best method but it can take a lot of time. For some people this is more a PITA then installing some watercooling (ask me!!!!). I've trying to get this CPU stable now for three weeks and its starting to show some results now. However others will manage a stable and decent overclock in a few hours or days which was the case with my previous comp. It all depends on what hardware is used and even then not two pieces of hardware are the same. Hence it is hard if not impossible to give some numbers which also apply to your hardware setup.Quote:

Someone should post those voltages here, or make a new thread in the OC help area so people wont fry theyr HWQuote:

I have done a lot of tests with my new corsair ram kit :
nomore memory error with memest 2.01 but always some random freeze during stability test !!
For exemple , i make a first Cpu stability test during 4 hours without any problem . The following day I do again exaclty the same test and my computer freeze 20 minutes later l !
This motherbaord is really crazy . :shocked:
I had never seen this before with P5Bdeluxe or P5Kdeluxe . :shrug:
If anybody has got an explanation about these f...ing freeze ! :down:
I precise that i tested an other PSU but no improvement .
My bios 505 parameters :

I am going to try some settings tonight and I'll let you know how it goes. As a side note I found this timing calculator not sure if its applicable to this board although it is for X38/X48 chipset. http://www.peakin.com/x38/calculator.html
Aquike question. What is the purpose of the SuperPi test and what do you look for after each settings change?
SuperPi testing for me has been helpful in terms of finding stability. I have found this board very touchy with a quad core and 4GB ram. Mainly it has been the ram settings that have been the most headache for me. I have found that adjusting clock skew has been helpful for me in achieving stability. If I was at an unstable setting, SuperPi would crash the system even if Prime95 would not error.
Interesting ! I am in the same situation : a quadcore and 4GB .Quote:

I have some weird issues to with this board but don't know if its board or CPU related. A few pages back I described my problem. It comes down to that I need a lot of voltage (approximately 1.45v) to get this E8400 stable at 4Ghz. Also when LLC on auto it has a total drop of 0.067v and therefore I use performance at this moment.
You got 4x1GB or 2x2GB or 1x4GB Dimms?Quote:

I manage to stabilize my system (FINALLY) by reducing ram clock speed from 1800Mhz to 1600Mhz with pretty good timings (7-7-7-21-1N) and FSB 400 (multiplier 9.0). The only other things changed are DRAM READ and WRITE CONTROL (both disabled), LLC (Normal) and SPECTRUMS (both disabled). Vcore is set to 1.360V (CPU-Z reading - in BIOS IS two or three clicks more) and Vram is set to 1.8V (stock voltage was 1.9V with 8-7-6-21). The rest left in AUTO.
SuperPI and Prime95 (several hours) passed with flying colors and S.T.A.L.K.E.R. played (Vista Ult x64) 2-3 hours with no crashes or BSOD... :up:
And a tip to cool down the NB heatsink... Get one or two small fans (the size of the fans Corsair uses for its 3-fan RAM add-on) and with a silicone gun put a few drops on the ASUS logo and press the fan(s) onto it. Leave the PC a few hours off (so that the silicone gets concrete) and... voila !!!! You have a pretty effective cooling system for the P5E3's heat sensitive NB chip... :)

Hah, was a while ago i thought the sensor on this board actually were the NB ...gotta go be back later with the rest hahaha ..
You should look at OCZ forum there are some stickies written by Tony with advise on how to get 4gb stable and how to set up the P5E3-Premium.Quote:

Are these the regular OCZ forums? If so perhaps we should post them in the OCZ support section here on XS as well.Quote:

Isn't 1,65v on the NB a bit high?
No actually, Asus has set the bios so that when you are in AUTO mode and you reach FSB 450 it sets the NBv to 1.6vQuote:

So far the AUTO settings (except CPU and RAM) serve to my system stability. In several previous attempts I tested NB volts up to 1.65 (with 4x1gb modules of 1800Mhz ram) but never had an error-free Prime95, and even got random BSOD and reboots.Quote:

Hi, could some one show a Spi1m &/or 32m screenshot at 3.6Ghz/4Ghz with this board please ? or at 4.2Ghz and if possible 600x7 ram@900 cas7
Edit: here is what I do these days: 40GP spi32M: http://images4.hiboox.com/images/330...6cb3a34453.jpg
and this is on GA-X38T-DQ6. I was discovering my wolfdale cpu at that time, didn't dare to set vcore as low as I do now:
http://images4.hiboox.com/images/330...e0eae8185e.png
I have my system running now at 400fsb 333NB strap (8 multiplier) which put my memory at 1601MHz. I jumped it up to 425 and the memory went to 1700MHz. I will post my setting a little later as I want to ask the question about the fsb/dram ratio, it is set to 1:2 per CPU-Z. How does one go about changing this? As I increase the FSB I do not want to overclock the memory to far.
