Overclock E6400 + P5B Help me :)

[kixo]

Here is my rig:
E6400
Asus P5B
Corsair PC2-6400 2gb ( 1gb x 2)
Evga 7600GT
SonataII Case with PSU
Have installed aftermarket Cpu heatsink, and VGA Heatsink

i run this computer 24/7, would like to get some tips on overclocking it
thinking about upgrading videocard and adding more ram, 2gb, with the addition of Vista

im gonna need help with setting up the voltage etc. and how do i make sure it will be stable? program etc.?

thanks in advance

Welcome to anandtech. These two guides should help. Let us know if you have any questions about them. How to overclock an Athlon 64, and how to guide for stability.

I had the P5B with a E6300. The sweet spot for my system was 450FSB x 7 multiplier. I set the cpu voltage to 1.3875v in the bios. With vDrop it delivered the stock 1.3125v to the cpu. With this voltage the system ran stable and relatively cool. I have Crucial Ballistix DDR2-6400 with 1.9v @ 450FSB (you could also try 2.0v or 2.1v dependant on your ram). Most of the other bios settings were on AUTO. I left the Dram frequency, PCIE on AUTO. The FS Termination Voltage could also be increased to 1.3v or 1.45v to increase overclocking performance.

It also ran up to 470FSB with this same 1.3875 bios voltage, but was not Orthos stable. The maximum was 533FSB x 7 with 1.60v in bios (effective 1.5v), a 100% overclock! Not sure about the 8X multiplier with the E6400. The ram divider (bootstrap) changes from 4:5 to 1:1 at 401FSB and above, with AUTO Dram settings. I also kept the ram Cas timings on Auto, or the system would not post, even with the loosest timings. I used MemSet in windows to set my Cas timings.

Don't let anyone tell you the P5B is not good for overclocking. The only thing holding me back from increasing the 533FSB x 7 (3.73 Ghz) was the 2.1v maximum Dram voltage. Perhaps 410FSB x 8 or even 450FSB x 8 could be attainable with your system.

i got mine to 2.9ghz but doesnt seem to be faster, geting 3dmark to test it, its running stable but memory seems to be running lower than 400mhz after overclock
any tips on P5B overclocking?

Umm, I might have been tired when I posted that. How about the thread that's stickied at the top of this forum, for overclocking C2D's and C2Q's, then?

mind telling me how can i change my memory timings in bios?

 

[myocardia]

Yeah, actually I do. Maybe you should try reading the overclocking thread??

edit: For $100, if you pay the shipping both ways, I'll actually overclock it for you, if reading is that hard for you.

lol i was overclocking then i setted up my settings to 4 4 4 12

Okay, you're going to have to read your motherboard manual, to find out whether your motherboard has a self-resetting BIOS, or not. It should, but I don't know for sure. Here's how to "hard reset" your BIOS:

1) Unplug the PSU from the wall.
2) Hold in the power button on your case for ~1 minute, to discharge all of your capacitors.
3) Remove your motherboard's battery.
4) Change the jumper position on your motherboard from the "normal" position to the "reset" position, and leave it there for 10-15 minutes.
5) Reverse all of those things, starting at #4, and work your way back to #1, skipping #2.

edit: The jumper I mentioned in step 4 will usually be the one closest to the battery, and 99% of the time will actually be labeled. Oh, and leave your memory timings high. Lower #'s is essentially "faster", yet it will lower your overclock, so leave them high, until you've found out how high your processor can go, then you can try tightening them. Didn't you read the overclocking thread I linked?:laugh:

thanks a lot saved me
after that i followed the timing of my Corsair XMS2 PC6400 Ram, 5-5-5-12.
seems that if i try to make it to 4-4-4-10 wont boot, its running at 2.1volt atm
I have fbs at 343, at stock voltage, running at 2.74ghz, stable, 35C idle and 44 on load from Orthos

got a lot to work on aiming for 3.0ghz with maybe little voltage increase

suggestions?
