Alright man you telll me what the hell you think then.

1333 fsb - 882 ram linked - 3:2 or whatever
Vcore - 1.285
Dram - 2.11
HT - 1.3
NB - 1.34
SB - 1.5
Ram Timings 4-4-4-12-2T
Passed The Test Perfectly.

FSB 1512... No matter what I change the HT, NB, SB, LDT Frequency, Set the ram timings to 5-5-5-15-2T, Set the MHZ to 754 so its 1:1 setten it to 801 so its 10:11... or setting it to 851 so its 8:9 NO matter what I change Prime95 Bend Shuts down the computer at the Same Exact Spot.. Its its my ram.. pease explain. or Use your Master-De-Bater Profile to use your best judgement on this.
 


I guess your vcore is low.
 

I'll tell you what, I too had a really hard time getting my ram stable. So I said to hell with this and left the ram settings to stock, or rather it's rated settings. You're running DDR2 800MHz, correct? So try linking the ram and use only FSB of 333MHz or 400MHz or whatever that will give you 800MHz for the ram.

Mean while I'll think up something up if this doesn't work.
 
the ram timings seen to have nothing to do with anything. I tryed Linking the Ram at 1:1 while it was only 757mhz total instead of 800.. With timings of 5-5-5-18-2T.. still shutdown the computer. Its like, The same place everytime.
 
like right now my settings at 1333 fsb.. Is like 888Ram 4-4-4-10-2T, 2.11Volts. and it doesnt shutdown the computer when that test number hits.
 
and its not the vcore being to low. I had small fft for 13hours stable at 3.4ghz at 1.5vcore ... and I set it up to 1.525 to test it out on blend to see if the computer will stop shutting down. It doesnt..
Its like 42mins though
its like
Test 1
1
2
3
4

Test 2
1
2
3
4
5
6
7
8
9
10 - Shutdown. (40mins give or take)

no hardware errors occur if this helps.. as well as no info on a error happening in prime95 in the results.
 
K im ofically braindead.... it didnt shut the computer off.. its not the ram .. it cant be the ram


What I am going to try do to do is this 1600FSB x 6multiplier ~ 2400ghz. Im going to set the HT NB SB so that the 1600fsb works. then set the cpu to it. If HT - 1.3, NB - 1.34, SB - 1.5 worked for 3.0GHZ what would you set it to for 1600fsb???
 
I have just now updated to bios version 0601 which is suspose to fix the video corruption... and watching this avi on wmp11 i can say.. I think it did the job. I have read a guy using a E8400 who is completly stable at 4.0ghz at HT - 1.42 NB - 1.42 SB - Auto. If he is using a different chip would the ht and nb and sb be the same for me as well???
 
Been reading around...apparently this motherboard is hell to OC.

To answer your question, normally the voltage should be around the same, give or take.

If it's not the ram, then it's the motherboard, but...good luck on that! That's about as far as my experience goes, so if there's any other questions, ask away! I'll await the updates.
 
Alright evilon its like this.
1600 X 6Multiplier
Vcore - Auto
Dram - 2.11
HT - 1.42
NB - 1.42
SB - Auto
This passed

Set the multiplier to 8X right.. set vcore to 1.425... It shut down on the 3rd main test. So right now I set the NB to 1.52 and I set the Vcore to 1.45 Does the NB have to be higher if the chip that your ocen is oced more.
 
I have a totally stable FSB of 405 with a NB of 1.38. As a matter of fact, i found that when I raised it, it caused more trouble, like freezing, and degradation of performance on tests like 3dmark.

Gained stability and 150 points Via lowering the NB. Although I am using a different VID than you, and I begining to think that what is stable at 3.2 @ x.xxx vcore isnt stable by simply adding VCore and changing the Multiplier, like is possible on virtually every semi-newer intel based board.

That blows! i will be doing random tests as usual to see.

This is kinda fun. I had gotten used to finding a stable FSB first via a lower multi, and then just adding the VCore and multi later, when stable.

Hell no on the NVidia boards! It appears that I cant even change the FSB by one point or it fails to do anything but freeze when loading junk in the background when the desktop appears.

Funfun!

could having 2 fans in my system on high, and also my graphics card fan speed on 100percent be making the system turn off???? also I have the NB fan hookedup... could that affect anything.. One of the fans in my case that is on high is a 120m and is hooked into Cha1.. Can that be drawing power from my motherboard making stuff instable??? Like I have 2 top fans as exahuast 2 120mm . ones pluged into Cha1, the NB fan is pluged into cha 2.
 
fan will only do good to the system. well unless your PSU is weak.

lower the CPU multiplier and up the FSB. so maybe upto a FSB the memory will be in good frreq to link to the CPU. always leave memory multiplier to 1:1.because doesnt matter how much you run the memory at it will be limited by FSB. use everest to see for yourself. dont be fool by those 400FSB+1066 ram.it just wont get you any extra speed.
 

You know, I actually found out that having too many fans and incorrectly placed raises temps. The side fans in the CM Stacker is totally pointless. After some testing, removing all the side fans drops my CPU and motherboard temps down by 3C. Meh, 3C shouldn't affect his OC anyways...
 
Has nothing to do with any of that, my mb temps are like 35c when sitten. It has to do with the motherboard... cause the mb fken sucks. Ive read forums on asus' forum with other people with this prob. I think the ram still plays a apart in the instability over 3ghz. I mean.. the stock timings are 4-4-4-15-1T.. you set it to that and it blue screens instantly.. so yea.
 
JL. I've mention to you before that this board has FSB holes. Stay clear of them within 100mhz of each side. Like mine. 2.8Ghz and 3.2Ghz and 3.6ghz are instability FSB zones.

Find somewhere around 3.5Ghz or 3.3Ghz and be happy with that. You're trying to OC by jumping around different Rated FSB. It'll take you forever to find a stable spot that way.

Keep your memeory at 750Mhz or Below, unlinked. Get your CPU OC stable first, then go back and work on your RAM.

As far as the ram timings, just don't use the 1T command rate if it blue screens on you. You won't see any perceptible difference

And lastly, you paid for a Toyota, but complains that your Toyota sucks because you see people in Mercedes that have better luxury options and more features in their cars.
 
Actually I got my fsb stable at 3.4ghz, The HT voltage needed to be at 1.24, not 1.4 like I had.... And by the way, My computer just hit 18,206 3dmark06... Sounds like a pretty sweet ass system to be bro
