The Phenom II List of Overclocks

[soundood]

I went for it. I picked up 8GB of G.Skill DDR2-1066 just now. It's supposed to clock well, but I'm wondering about the PII IMC. Has anyone had luck in doing 1066 with 4 DIMMs yet?

yep i have been doing 1066 with 4 dimms populated 2 x 2gig and 2 x 1 gig, all running at 2.1v dimm, and stack vcore on CPU and CPU NB, i had to add .1v to my CPU and CPU NB for my 9850 to take 4 dimms, even then i would get the odd BSOD

I have issues running 4x2Gb too. Memtest fails at 1066. Down to 800 now and testing from there.

Tried NB up to 1,5v and RAM up to 2.28v with no difference. My CPU/SB temps are very nice but need to check ram temps.

[mongoled]

you can do 3.8 stable on air too

Thats a great clock, and one of the better CPU's, only thing small FFT's dont stress the northbridge of the CPU.

At least with my current Phenom, the difference in clock speed with regards to stability comparing small FFT's to large FFT's can be as much as 150mhz...........

[crazydiamond]

what is your guys max trc in bios for phII?

[PetNorth]

This is what I've achieved so far

CPU Frequency: 3700MHz
CPU Vcore: 1.4875v BIOS (mobo overvolts to 1.50v idle, ~1.52-1.535v full load)
NB Frequency: 2000MHz
HT Link Frequency: 2000MHz
Memory Frequency: 800MHz 4-4-4-12
Memory Configuration: 4x1gb
Memory Ganged/Unganged: Unganged
Mainboard: ASUS M3A79-T Deluxe
Cooling Type: Thermalright HR-01 Plus + 120mm @1200rpm (ambient temp ~25º)

I was watching temps, and that is what I started with. I will try large sometime. I already put it back under water. I just wanted to see if I could clock as well on air.

Well I spent most of the day seeing if I could coax more CPU out of this CPU, but I cannot. I didn't bother going down to 2 sticks because I want to run with 8gb memory. Even if I push the system to FSB 244 it is not stable (3.66GHz CPU). It's "close" at that point. I tried backing off the FSB to DDR2-800 with the same timings that work at 960MHz, and tried to push the CPU up to 3.7GHz but it was not stable, even with 1.6V on the CPU and 2.6V on the other BIOS setting (that starts with 2.5V, I forget the name!) Just to be absolutely sure I am going to keep it at 3.6GHz on the CPU, 2.4GHz on the NB, with 1.4V and 1.3V respectively as stated in my signature. Memory was also not stable up past DDR2-960, looks like I found all the limits I can, and will just have to be happy with it. I was really expecting more though.

CPU stepping?

How's this for a glory shot w/ stock volts? Stable enough to get a screenshot! =o)~

how about a validation?

Stock Vcore, very impressive thought it's only stable to ss

[Sgt.McRuff]

Normally have vcore at 1.536v but under high load my motherboard drops voltage a bit (.016) and after 10+ mins of occt at 1.52v (even thow it should be 1.536v) computer will restart. Only have it at 1.568v for occt. Edit: NB is at 0f (1.375v) Also cpu is on water.

validation and/or higher with a small increase in vcore or I call useless.

[NCspecV81]

guys, how does one validate his voltage? lol.

[ubuntu83]

CPU-Z validation link please.

[Rammsteiner]

Yes!

I think I solved my BSOD issues

There seems to be a hotfix for the 0x00000124 BSOD's which will be in SP2. It's some issue between multiple PCI(-e) cards or so

Anyway, what Ive done past days is got my RAID card working (I had to enable SATA controller in BIOS?), fixed BSOD's and got a stable OC

Ran 6h Prime Blend last night without errors, did a 10 run Intelburntest where the 9th run shown instability, all the other runs were good. I assumed this might be the IMC so changed it to 15 and did a 15 run after and no errors at all.

Maybe Ill give it another try in a while but for now Im more than happy

[NCspecV81]

CPU-Z validation link please.

I do not have one for that particular speed. However, just messing with the multi I have one upto 23x. Although, I found there to be much stability to be gained by keeping the multi low and the bus speed high, which was what I was playing there to see what I would need for a high cpuz run! Now, it's time for some volts and some bus speed!

That's on stock volts ? & what cooler?

[NCspecV81]

of course that's not on stock volts, but how does one verify their volts? I'm on a stock vapo ls right now. Well other than some fan mods and a duniek mount (which is bad arse of course).

[Final8ty]

I thought that there was supposed to be switches in in CPU-Z that would let you post the Vcore.

Really? How does one do that?

[Final8ty]

Just read up again & it seems i was confused with

Set to OFF (or 0) disables sensor chip detection and voltages measurement.

Why not just try with 2 sticks? Only takes a second to pop them out. 4 sticks puts alot of stress on the IMC. What do you do on your computer that requires 8gb of Ram?

sorry offtopic! but do you happen to play l4d? more specifically yesterday?
