E4300 and Asus P5N-E Sli ...what am I doing wrong?

[msi1337]

Got a heck of a deal on a near complete E4300, Asus P5N-E Sli rig.. I am trying to overclock it and it will not post past 1000 fsb QDR (or 250fsb for those who cannot divide). I have tried different memory dividers..always keeping the memory at or near 800mhz (it is 1x1GB OCZ SOE DDR2 800). The stock heatsink has been lapped and a fresh application of AS5 applied to the processor. I have all options that are not needed turned off.

Also, I have tried 5-5-5-15 for the memory, auto. Tried Auto for vcore voltage, and 1.325 also.

what am I missing..is it possible to just get a dud processor?

update: I got a freezer 7, and zalman heatsinks for the NB and SB and now I am posting at 2989mhz and stable at 2700mhz

no love?

This is interesting. Something you might want to try is to do a BSEL mod to get the motherboard to think it is a 1066mhz fsb processor which may help. If you have it at a different strap your board might oc it better.

Try increasing the Northbridge voltage to 1.56V.

Put a little fan on the NB heatsink, and use the heatsink on the Southbridge.

Put a larger metallic heatsink on the Southbridge with the enclosed 3M Thermal tape.

Attach the fan from this set to the Northbridge with a drywall screw, just enough to get a little "bite" between the fins.

Also, set the memory voltage to 2.2V, and obviously set the timings manually.

Set VCore to the max. 1.35V.

Hope this helps.

And try the CPU frequency of 1300MHz.

It will give you a nice memory divider of 16/13.

Good luck!

P35 boards are best suited for overclocking 800MHz C2Ds.

Maybe so... But he's got the P5N-E SLI now.

Before moving on to the new MB, lets see if we can squeeze a little extra from what's already on hand.

Yes try a little juice for the NB can't hurt to try.

What power supply?

Are you running SLI?

 

[msi1337]

This is my power supply

and I am running a single EVGA 7600GT PCI-E (takes nothing to power it)

I have just heard that it is uncommon for a E4300 not to be able to hit at least 2.6ghz

 

[nefariouscaine]

I had that same combo for a while and was getting 3.0ghz just fine

I'd say uping the nb voltage is a huge factor in getting my oc stable - more or less I'd try what JustaGeek suggested as those are the things I did as well

*fan on the NB* is a must for this chipset

 

[msi1337]

Picturemy motherboard already has huge heatsinks on the NB and SB

thats good enough on the sb but trust me the NB is going to need an additional fan on it -- that sucker gets hot

what are you doing for voltages across the board as I'm doubting the vcore is the issue at all

 

[msi1337]

I was able to get up to 2.7 following an overclocking guide from OCN

I am currently at 2.58...here are my settings

CPu:
2587mhz
287.5x9 (1150 QDR)
Core voltage: 1.328
Speedfan reports core temps at 37'C idle (stock intel cooler with AS5)

memory at:

5-5-5-12 command rate: 2t
all other settings on auto
memory voltage: 2.085

NB voltage: 1.393v

almost all other settings are auto.

what should I do next besides test for stability? I tried 2.7ghz and it was not stable in Windows using the above settings

 

[msi1337]

bump for update

 

[Zapper48]

You'll probably need a little more vcore.I run 1.38-1.42 for 356x9 3.2ghz.
About then you'll probably find your stock cooling will reach it's limit.

Msi,

I am stuck at 2250 as well. New to overclocking, looking for help. How do I check the temps of my Northbridge and Southbridge? My temps otherwise seem to be fine, but I am not sure about my ram. I have it set at 1:1. It says 250 Mhz in CPU-Z.

Learning.

Thanks for your post.

Update IP35-E to 12 BIOS. Reset CMOS and load Optimized Default. Go into BIOS and manually set RAM voltage to 2.0, and timing to 5-5-5-15. Use 1:1 memory divider. Increase Vcore to 1.465. Set FSB to 333MHz. Hit F10 to save BIOS. Repost at IP35-E review thread if you need more help for other IP35-E users.

The problem is most likely your RAM.
