I hit a plateau and cant OC my e6320 farther?

[Stephen8454]

Here are m specs:

Case: Antec P180b
Mobo: evga 680i
CPU: e6320
RAM: OCZ 2 x 1GB DDR2 1066MHz Dual Channel SLI Certified
GPU: GeForce 7600GT CO 256MB DDR3
HSF: Thermalright Ultra 120 Extreme w/ Scythe S-FLEX 120mm fan
2 x Exhaust fans (top and rear)
1 x Intake per chamber
PSU & HDD's in Seperate chamber

Ok, I had my first taste of OC'ing my CPU yesterday and was able to get my Conroe E6320 to 2.18GHz w/ the following schematics:

FSB - 1250 / 4 = 312.5 x 7 = 2.18GHz w/ a 1:1 FSB:RAM ratio (only allows multiplier of 6 or 7)
Vcore=auto
vram=auto
v(everything else)=auto

If I change the ratio to unlinked and keep the memory FSB at 1250 and up the CPU FSB to something higher like 1275 I end up getting a ratio of 8:15 according to CPU-Z (if it even boots)

I have heard users getting their e6320 up to 3.3 GHz but everytime I push the FSB to anything past 1250 it will start to boot and get the blue-screen-of-death. My guess is I have to start manually changing the voltage for CPU and RAM and memory timings.

If anyone would be so kind as to fill me in on what my next step would be to push my system even farther it would be much appreciated... If not does anyone know of any books that I could read that would teach me all of this?

You are increasing the ram too much. Your ram is rated at 2.2v, that should be the first thing you change. Also lower your ram speed to 1066 then increase the FSB to something higher. You should be using unlinked with the 680i it works best.

I will send you a pm with my msn, we can talk 1:1 for some config details.

awesome! My msn is stephen8454@hotmail.com and my AIM is stephenkacc

Drop the 1:1 memory ratio and that will let you increase your FSB.

 

[Stephen8454]

I read before that a ratio that wasnt 1:1 was bad but looks like that isnt the case for the 680i SLI chipset...

Should I have a multiplier of 6 or 7? I read that a smaller multiplier and a faster FSB would be ideal...

first off lower your multi as low as possbile so you can get rid of the memory overclocking element. Trying to overclock both at the same time will give you headaches.

Now, b4 you go raising voltage, just because your computer BOOTS doesnt mean the overclock is stable. You need programs to test your overclock:

Coretemp: 0.95 recient however on some systems, MAjorly bugged. Known to lock your computer. so look for 0.94 if your comp reboots or freezes when you load up 0.95

Othros, or SP Prime95. These test the overclock on your cpu. If it can pass one of these tests for at least 7 hours, its deemed stable.



Now, since your wall is at 1250 fsb, you need to check your upper FSB wall.

So first raise your voltage to 1.45V since your cooler is awesome. Then drop your multi to the lowest and raise your FSB so it = your overclock. If it doesnt go that high, it means you have a FSB wall.


This is only used for trying to see HOW high she will go. If you already got a nice number you want. Then go to that number directly on the 7x multi.

Then set your voltage at 1.45V Run coretemp and orthos for about 25min. Look at coretemp, make sure your temps dont exceed 70C on both cores.

IF it passes, lower the voltage 1, and repeat. Keep doing that until she freezes orthos or fails one core, or you get BSOD while booting. Then bump it back up one and thats your CPU setting. After that, you run a final orthos for 7 hours.

If your comp cant pass a burn in test @ 8 hours, its not stable. Reason is because it takes about that long for the thermal MAX at 24.7

This is also why most high overclocking C2D's cant hold a Orthos for 7 hours. If you WCG, and crunch, F@H is excellent at stability and so is Bionic. If you been crunching for 24 hours, and you produce 0 invalids, You cant question stability anymore. Its 100% rock solid.

And i personally dont care if your machine will do 4ghz. If it cant hold that for 7 hours straight, its not a real overclock.

Then you play with ram timings afterwards when you know your CPU is done.


Realistic overclock with that chip will be around 3.1-3.4 with acceptable load temps at 24/7.

If you want 3.6 your going to need to give her the full 1.45V, and you'll find your core temps fairly high. Might even scare you unless your on water.

That makes alot of sense to OC the CPU first and then worry about the RAM...

I am going to give this a shot tonight and see how it goes. To be honest, I have no clue what to do to OC RAM either...

 

[cprince]

You might want to loosen the RAM timing in order to gain higher memory speed. Also, not running the RAM and FSB at 1:1 ratio does result in performance degradation, but it is negligible.

 

[Stephen8454]

Ok, so here is what I got so far for the CPU OC'ing:

CPU = 3017MHz
FSB = 1725MHz
VCore = 1.4500v

I got it to boot w/ a FSB of 1750 and CPU of 3.06Ghz but havent since I tried upping it further. Should I stop here for the CPU and move on to the RAM?

 

[1ManArmY]

what are your temps?

 

[Stephen8454]

My CPU while under load is around 36C

:laugh:

And what kind of load is this, with what kind of ambient temps?

36C = way too low to be realistic.

 

[Stephen8454]

Yea, your right, loading as in rebooting alot... I have not tested it with programs to throttle the CPU yet. I have lavasys Everest Ultimate but have yet to use it or learn how all the tools it has...

It is 36C when it boots up, the A/C is on in the house set to about 65F and the vent aims right at the front of the computer...

So that being said, what would be my next step?
