My Overclocking Addiction

Post by spitter » Wed Oct 07, 2009 10:39 pm

I decide to buy the Fry's special. a Phenom II x4 805 for $80 , figuring that a quad at 2.5gigs is better than dual core at 3gigs. The 805 is a locked core and I promised myself not to try to overclock the thing because playing with bus speed on any of my AMD processors has not been good to me, but the urge to try is getting to strong, I am getting weak....can't keep myself out of the bios. I think I need some help, what the first step, drop the memory speed then up the bus??

Looks like we may be "helping" each other as we are using the same mobo and your mem specs look like my Corsair :) How far into the bios have you gone and how much have you oc'ed before?

Sadly I've just got off work and am totally whipped (it is 01:48 here). If no one else comes along I'll try to give you my suggestions, but yes lower the mem to 800, run 5-5-5-15 @T2 with vdimm at 2.1V. If you are running the stock cooler I would start with the FSB @ +2 each time and see if it will run a 8M run of Super Pi. However to get anywhere you will need to up the vcore and that calls for an after market cooler also to do any serious oc'ing you'll need to look into cooling the mosfets also.

Off good start, my heatsink is a mugen 2, so it will work for the time being, dropped the memory setting to 667 mhz and changed t1 to t2 manual, set the bus to 232 and I am running prime95 right now, 3dmark ran perfectly and so did aquamark. Upped the cpu voltage and can do it some more. primes been running 30 minutes now and has topped out at 43c, good night I am letting it run all night.

Don't know what the stock vcore is for the 805, but that appearst to be a good start and wouldn't up it anymore until you start having stability problems. Your HSF I would think will be fine for what you'll be able to do, however one thing I will strongly suggest is be add some passive coolers to the mosfets as Biostar mobos have been know to cook one or more with oc'ing. In my mATX case I'm water cooling so I did the passive and added a fan above them. Since the mosfets on this board are kinda laid out rather “uniquely” I ended up using the Enzotech BMR-C1s left over from doing the M3A78-CM in Kermit. These are for video cards and their 14mm square size allowed me to cover 2 chips at a time. I then finished it off with Enzotech MOS-C1s for the “little” guys.

As finances permit, I will get some of those little copper coolers, two boards and two video cards make it a little bit more then I need to spend right now, stock voltage for the 805 was 1.25 volts in the bios, 1.238 off the diode. The overclock bios setting is 1.4(it is locked at 1.3 with a .1volt startup boost ) .

As I've never dealt with a quad-core I'm not quit sure how Super Pi would work with it, but I use that for "quick" testing before doing the time consuming ones like Prime and OCCT. Hope some picks up on this to make reccomendations of some quick test software for quads to speed your attempts up. I usually use Super Pi to "take it to the limit" and then back down the values for "stable" settings testing. :)

Seem to be a good quick test for Quads, PI is good but since it is only a single thread for quad you have to start it 4 times, dropped the volts by .05(currently 1.312) and the temps have come down by 5c. :mrgreen:

IntelBurn is pretty good, but be very careful using it with AMD as I've seen it fry one!

Well, it's stable at 3gigs, with the voltage at 1.28, temps top out at about 38c, had to drop the memory speed down to 533 mhz. 3gig is what the last processor topped out at on this board, and no amount of volt increase would get it stable above that, so I think it is maxed out, I'm very happy with 3gigs. :)
