The Phenom II List of Overclocks

**daellum67** · 01-20-2009, 02:25 PM

i pulled my true to get a look at the stepping, the cellphone pics I took before i installed the chip the first time weren't good enough to see it

CACVC AC 0850BPDW
http://www.daellum67.com/IMG_1409.JPG (used an SLR this time)

it's acting very strangely atm, i am able to run vantage and validate at 257x15 (3.855) but bsod's before the windows loading bar comes up at 258x15. it was loading at 55C during the vantage run.

my board wont boot at all if i try to give the chip more than 1.525 vcore, and after droop this limits me to 1.5v real

im going to try an updated bios and see if this helps my clocking any

Stable

Suicide

Thx for great table... but mine is not a real sucide i did Super pi1m thats abit harder than sucide but not hard like occt/prime. Maybe 3 tables?

Awesome clocks reguardless...

An AMD, under 15 seconds SuperPI... SWEET!!

Holy mother of god!
That's Core i7 territory man!

I'm running with some very good water cooling, and if this is achievable, I have to rethink my whole workstation upgrade!

the suicide table is more of a table for chips without 2 hour prime or one hour occt. so its not confirmed if those chips are completely stable.

dfi 790fxb-m2rs|h just got a beta bios update. major reasons of change: ability to change HT link.

will report back with HT oc results.

**daellum67** · 01-20-2009, 05:03 PM

the 920 i ordered just got here. im going to have one more go at clocking my 940BE before i swap it out and try the new chip. the stepping and batch on the new chip is CACVC AC 0849BPCW 0228

im checking on that now

dfi's site is back up for me
edit: that bios raised my max validation. dont know the new max yet, but the old one was 3.85 on 11/25/08 bios. just got into windows at 3.9 and its stable enough to make this post.
http://valid.canardpc.com/show_oc.php?id=489191
with luck it'll raise my max stable OC or at the very least allow me to reduce vcore.

chew* · 01-20-2009, 06:23 PM

Ok i'm all up and running just installing system mechanic so i can easily backup the registry in case of failed OC's.

Curiosity why does AOD not start due to not having an AMD cpu installed?

790gx board, IIRC everything is set to auto for now. Ran as administrator and the whole 9 yards.......beats me. Just want to monitor temps

**jakefalcons** · 01-20-2009, 07:17 PM

using the bios 1/19 for the dfi lanparty 790gx jr i was able to get 3.75 pretty much stable but it bluescreened after 5 hrs of occt im almost sure its the bios stability just isnt there yet but atleast i can change the multiplier now, and it boots at higher fsb's i still have a hypertransport wall though that i just cant get past...

**Cybercat** · 01-20-2009, 08:17 PM

I'll check out that beta BIOS later but I'm not expecting big things. Not until they fix that voltage table issue Brother Esau was talking about.

**NCspecV81** · 01-20-2009, 09:51 PM

Anyone know about the A79A-S and a beta bios? I'm tired of guessing what my multiplier is going to be by using HEX in the bios!

**BertM** · 01-21-2009, 03:15 AM

particle, i had nb 2210 on that 3817 clock!

**Particle** · 01-21-2009, 06:13 AM

@BertM: Ok, I'll update it to reflect this.

@NCspecV81: The latest (P06) BIOS for the A79A-S still shows hex in BIOS.

I don't know for sure that this chart is accurate, but here's how it should correspond:

8 = 4x
9 = 4.5x
A = 5x
B = 5.5x
C = 6x
D = 6.5x
E = 7x
F = 7.5x
10 = 8x
11 = 8.5x
12 = 9x
13 = 9.5x
14 = 10x
15 = 10.5x
16 = 11x
17 = 11.5x
18 = 12x
19 = 12.5x
1A = 13x
1B = 13.5x
1C = 14x
1D = 14.5x
1E = 15x
1F = 15.5x
20 = 16x
21 = 16.5x
22 = 17x
23 = 17.5x
24 = 18x
25 = 18.5x
26 = 19x
27 = 19.5x
28 = 20x
29 = 20.5x
2A = 21x
2B = 21.5x
2C = 22x
2D = 22.5x
2E = 23x
2F = 23.5x
30 = 24x

**Rammsteiner** · 01-21-2009, 09:59 AM

Damn, Im going to get some real watercooling really. My air is holding me back

In need this thing at 4Ghz, I just need to

Also is it me or is forum a bit of

ed up? Everytime Ive to press 'post reply' to read the latest posts

Nice chart, but 13 in the bios is actually 17.5x for me.

**merkk1** · 01-21-2009, 10:27 AM

The chart is wrong for cpu Multi in hex For the foxconn board i have it written down at the house i post it when i get home from work.

NCspec, did you have to update your BIOS to P06 or did it come with P06 when you bought it?

**keithlm** · 01-21-2009, 11:56 AM

And in the A79A-S bios 14 gives me 18x for me. (But then so does 15 and 16 and 17... I think it is "capped" at 18x in the bios for the P06 bios.)

**merkk1** · 01-21-2009, 12:07 PM

Yupper Keithlm there is something up with bios on the highter hex code dosen't work i have to use AOD to get the highter mulit for
the cpu to work on the a79a-s. I think it stop at right around x18.5

**dawei213** · 01-21-2009, 02:20 PM

Those with the Foxconn mobo's, did it come with the P06 bios, or would I have to get my hands on another AM2 cpu to update the bios to support the 940?

**Particle** · 01-21-2009, 02:49 PM

The Foxconn works just fine without P06. Your CPU will show up as unknown but it'll operate just fine and clock just as well. So, I'd recommend you boot up with your 940, flash, and then go on.

**merkk1** · 01-21-2009, 04:07 PM

I been using this list for overclocking cpu multi so far its works good for me .

1= x8.5
2= x9.0
3= x9.5
4= x10.0
5= x10.5
6= x11.0
7= x11.5
8= x12.0
9= x12.5
A= X13.0
B= X13.5
C= X14.0
D= X14.5
E= X15.0
F= X15.5
10= X16.0
11= X16.5
12= X17.0
13= X17.5
14= X18.0
15= X18.5
16= X19.0
17= X19.5
18= X20.0
19= X20.5
1A= X21.0
1B= X21.5
1C= X22.0
1D= X22.5
1E= X23.0
1F= X23.5
20= X24.0
21= X24.5
22= X25.0
23= X25.5
24= X26.0
25= X26.5
26= X27.0
27= X27.5
28= X28.0
29= X28.5
2A= X29.0
2B= X29.5
2C= X30.0
2D= X30.5
2E= X31.0
2F= X31.5
I hope that helps out the foxconn guys that need to know the hex code for there cpu bios multi setting .

Thanks for the response. Well, I just got the following:

Phenom II 940
Foxconn A7DA-S
OCZ Reaper 4gb 2x2gb DDR2 1066
MSI R4850-512M Radeon HD 4850
PC Power & Cooling S61EPS 610W Continuous @ 40°C EPS12V
Sunbeam CR-CCTF 120mm "Core Contact Freezer" CPU Cooler

Hopefully it'll make for a fast machine

chew* · 01-21-2009, 05:58 PM

For the time being, Ill smack up a 24hour after I decide which bios I'm going to stick with.

Gigabyte 790Gx/OCZ vindicator......

hell of a machine i recommended every single part to one of my friends. thats about the best perf/$ machine you can get.
