e6300 + P5N E SLi

PyroboyUK · 6 Jun 2007 at 15:46

In need of some advice....

I am trying to overclock a pc with an E6300 + and the motherboard is an Asus P5n E Sli. I tried using the AI overclock but all i can manage is the 10% clock at most, i have tried 15% and 20% but the computer just doesnt start up.

I have looked at a guide that tells me to change some voltages so i have done that fine and i have set the CPU frequency, the max for the motherboard seems to be 131 so i have to play with the multiplier but although it says the max is 50 everytime i change it from the default 7 no matter what value i try it changes it but when i try to start up it just resets back to default....

Any ideas?

Thanks

Your better overclocking from bios go up about 10mhz at a time.

Look into the official P5N-E thread for detail info.

The multi is locked on ALL Intel CPUs apart from the extreme editions. You can downclock the multi on P5N-E but it only works with BIOS rev. 0401 and below.

As said don't use the AI booster choose manual instead and set all settings yourself, again the official thread has tons of valuable info.

Which frequency are you referring to?

I may have been going a bit quick, seems i was looking at the PCIE which i am assuming is PCI express, so 131 is the max value it can be set, but becuase i am trying to do the CPU i assume that is not needed. In my motherboard i have a section in jumperfree were i can set the CPU frequency. But on this model i cant find that anywere....

It's on the same page as the PCI-E frequency...

It's under the FSB and RAM frequency menu, the default fsb should be 1066, increase it a little bit at a time (I increase it by 50 at a time) to overclock.

Set the ram to sync mode but make sure the speed is within your ram's spec.

go to voltage and set vcore to 1.25V, fsb to 1.35V, RAM to whatever is recommended for your RAM and vcore offset to +100mv.

Also set the PCIE to 100.

Set fsb to 400 and set vcore to 1.3v should do it no bother and stress it.

Done all of the above, however FSB was default at 1173, tried going up but it just locked up.

My mistake the FSB is 1066.

Barrymacp:

I am a bit puzzled on setting the FSB to 400, the min is 530 (i think) its around the 530 mark anyway.

steve258 · 6 Jun 2007 at 16:49

I think what he meant is the "actual" fsb 400Mhz which is 1600Mhz "effective" due to Intel's quad-pumped fsb. The figure displayed in P5N-E is the effective figure.

However I won't set it to 1600 immediately I would increase it by 50Mhz each time then save-restart until it won't post anymore in which case increase the vcore in 0.025V increments.

leave all voltages as auto to start with.

set the ram to be unlinked and set to 667, then try 1204/1208 and 1212.

barrymacp · 6 Jun 2007 at 17:10

I dont know one E6300 that aint did 2.8ghz on 1.3v with a setup like that

V|per · 6 Jun 2007 at 17:14

i do, i have seen plenty of e6300's that don't do 400fsb on lower than stock voltage

barrymacp · 6 Jun 2007 at 17:48

The past five i have tried did 2.8ghz fine 1.3v

You should also be aware that many of the P5N-E boards have an FSB "hole".

For example my P5N-E will boot at 1200MHz FSB but then there is a big whole up to somewhere over 1300 MHz and will then boot all the way up 1500MHz.

also bear in mind u can have problems with 00, so use 04/08/12 (ie 1204, 1308 ) .
