FSB won't get higher than 350 Mhz...

DL and flash the latest BIOS, then try again.

That's about the first thing I told him to do, but it didn't fix his problem .

Temps are about 42-44 idle and won't go hotter than about 49 degrees under full load...
monitored with both, coretemp and real temp 2.60 with tjmax set to 95 degrees.

You really think it is !? Got my OC rock solid stable with it enabled @ 1.4 volts...see my sig.

Sorry if I sound ignorant, but as you may have noticed, english is not my first language . So that being said, what do you mean by " a pad-mod to 400 Mhz " ???

A pad-mod is the same as a pin-mod(which were done on non LGA-775 CPU's) It's a mod where you trick the motherboard (by way of the CPU) into thinking that the default FSB is different than it really is. So, on the E8400, the default speed is 333MHz with a 9x multiplier. By connecting the right pads(pins), it will set the default FSB as 400MHz...meaning the motherboard will "see" the CPU as a stock 3.6GHz(400x9). This generally works better on lower-end CPU's that start out with a "low" FSB of, say, 200MHz..or 266MHz. If the Cpu can run at the modded clock-speed with stock vCore, then it should work..assuming the new speed isn't beyond the chips reach. If it can't run the new speed at stock vCore, you can do a vCore mod(using the same method as the pad-mod, but joining different pads/lands/pins )... or just forget it if you don't want increased vCore. Many, but not all, E8400's can run @3.6GHz with stock voltages..so this would work... but realize that many won't, and will need a vCore-mod.. or have to be left at the stock speed.

Here's the mod

Consider loan line like a damn to a river.

Too much pressure can build up and the dam can fail.. same thing with a cpu.

vdroop is there for a reason.

Thanks for the explanation... but I don't think he'll go that way... sounds a little risky to me

I see ! so now you convinced me to disable it... hope my system will remain stable !?

By the way, I haven't heard of my friend since I started this thread... I should see him today, so as soon as I have some inputs on what's going on with his OC, I' ll let you guys know. In the meantime, I'd like to thank you all for your concern...

Ok, here's everything he did :

• updated bios to latest version ;
• boosted cpu voltage to 1.35 to see if it boots ;
• Somethings he didn't do, is try with only 2 gigs installed and re-seat his hsf ( guess he's too lazy ).

Right now, he's been running Prime95 (large ffts ) stable for 3 hours with these
settings :

• cpu voltage @ 1.35 ;
• FSB @ 435 Mhz ;
• DRam @ 1451 Mhz ;
• Cpu ratio @ 9 ( gives him a whooping 3.9 Ghz )
• Everything else @ auto

I was just wondering if this Ram frequency seems safe to you ( I have to say he has the corsair Ram cooler installed ). What I think he should do to be sure, is run a "blend" test in Prime, just to be sure... What do you guys think ???

Thanks in advance !


EDIT: I just touched is Ram, and it runs cool as a cucumber ;)... so I guess it's ok. Anyhow, any opinions would be appreciated...
