The Phenom II List of Overclocks

[Rammsteiner]

K, Voltage/clock scaling is a bit off but at least I ain't hitting a wall regarding clocks.

I just passed 5 runs of Intelburntest @ 3.77Ghz. I needed +0.15V for that though.

Right now my OC is as following;

3.77Ghz CPU, 2.03Ghz NB/HT, DDR1160
1.488Vcore (CPU-Z idle reading), 1.2Vnb (might not even be needed but to be sure) and 2.16Vdimm (might eventually be able to lower that to 2.14?).

Full load under Intelburntest was ~47C Next attempt will be a HTT of 292, this will result in 3.796Ghz CPU, 2.056Ghz NB/HT and DDR1168. From there Ill start trying to OC the NB even more but Ill leave the CPU alone now I guess. Im more than happy right now

PS, this is all in Vista x64

that IFX-14 looks like its doing a great job keeping that cpu cool is it lapped?

Not so cold outside about -6c and some window action. Sry about my windows paint skillz :p

so it appears that it is not very hard for the nb to reach 3ghz. its more of a problem for the hyper transport. can most people here hit 3ghz northbridge with the ht at stock or any other value?

[HondaGuy]

Oh, you big hairy arse LOL. That is the only O.S. I do not have.
I do clock better in win XP 64, well it seems to be more stable. verry nice

which OS would you like?

post another pic let see what you have gotten so far so I can try to beat it....

roofsniper: I have been able to hit on HT@2744


Wprime HT@2755

Nope, actually Im not even happy with the way I applied AS5 on it, really done stupidly. Im even wondering if the whole IHS/heat sink base are covered with AS5

I just finished a 8 run Intelburntest with the CPU at 3796Mhz! Only 1.488Vcore reading from CPU-Z (at idle, it drops a bit under load). RAM seems to be stable as well at DDR1168 which is of course awesome. Next thing Ill try is to get the NB at a multiplier of 8 (2336Mhz) or even 9 (2628Mhz).

Then a bit of timing tweaking on the RAM and Im ready to rock.

Only have to upgrade firmware on my RAID card since I got the BSOD 'non-ACPI compliant' At least, I hope a firmware updte will solve it. Then get the HDD's back in RAID 0, re-install everything and rock on!

Dose it drop .016v under load? I thought it was bios or motherboard, but kept telling myself psu.

I have'nt even played with HT yet. will do that later.

[Raiderman]

I would like to know what the voltages are on the NB and HT, please?

[Rammsteiner]

Yeah, something like that. Unless my PSU is ed as well I guess it's the board

[pershoot]

this thing is a beast. 2.6GHZ nb looks good. will need to sort some heat issues out before pushing on with the cpu clock (it has more room left in it). dont feel comfy giving the NB much more juice then this for higher clocks on that, but we'll see...

cpu reminds me of the old athlon xp barton mobile days. the fun of OC'ing just came back to life

[Oldguy932]

Ok guys, there's some benchmarks at higher speeds. I tried for higher but its a no go, maybe with another bios I could get 4.5ghz working, but not today. Got me a few extra points on the bot though, 3rd in both 32m and pifast now.

[Titan7171]

Yay my toys came, I got the same stepping as pershoot and daveburt

[roofsniper]

hey does anyone have any screens of comparing nb clocks? im thinking about running 3.5ghz which i can hopefully get on stock voltage but im not sure about the nb. does anyone have any screens testing different nb and ht speeds?

[Raiderman]

Just like Christmas, isnt it?

[demonkevy666]

oh an H.D.T heat sink good see my sig lol
I want to know your temps stock and OC.

I will be on my thread, I have laid out the 2800NB scores first.

[Raiderman]

Here is my overclock. Im gonna let this thing burn in for 24 hours then try prime.

All other info is in my sig!

I think I might like windows 7 after all.

well here is one on windows 7 32bit



and one in windows 7 64bit

[Raiderman]

Wooohooo 4 ghz....nice!!!

[drunkenmaster]

Is that 1600ht accurate?

AT the moment I'm just playing about with overclocking, the HT frequency option in the DFI fxb-m2rsh board doesn't seem to be altering anything unless cpu-z isn't reporting it in windows 7 64bit. Though its tracking nb speed and core clock fine at the moment. Is there any trick to changing the ht frequency without raising the bus, some option in the bios that needs to be set?

3.6Ghz was a breeze but 3.8Ghz would get iffy getting into windows, mostly not making it. Is it still the case you really need the HT at over half your core speed and equal to or less than northbridge clock?

Ya, it automatically drops it in bios when I set the NB above 2600mhz. I get tired of opening AOD to set it. I can't boot if I take HT off of auto in the bios for some reason, regaurdless of settings.

@ Raiderman,
Thanks man. Windows 7 seems to be real stable

My older DFI 790FX is doing the same thing, It's not actually clocking the HTT unless I change the HT clock, it seems to be locked in at 1800mhz.

only way is to adjust htt to get your ht higher then 1.8. it didnt work with
phenom I either.
