Phenom II steppings and max OC 550-940 - Page 223

post #2221 of 2829
Help me out fellas! I'm at an HT wall of 277 (3.86GHz - 1.53v), can't go higher than 277. I've tried lowering the CPU multiplier, adding voltage in certain areas, sadly nothing is working. Here is my highest bootable:

System specs:
Phenom II 920
ASUS M4A78-E
G.Skill DDRII 800 4GB
XFX 4870X2
D-Tek Fuzion II
Swiftech 3x120 Radiator
84CFM fans on the Radiator

well.. i put it away for a while..

* Phenom II type 940
* CPU stepping 2
* manufacturing date where do i find that?
* Revision RB-c2
* max CPU clock speed, reference clock and multiplier 3692.49Mhz, 211Mhz multi is 17.5
* CPU voltage is 1.45v
* CPU-NB voltage 1.2150v
* Northbridge clock (check CPU-Z) and voltage 2000Mhz, voltage, i dont think i messed with it.
* HTT link speed and voltage stock
* motherboard used asrock 780gxh
* motherboard BIOS revision 1.2
* type of cooling (3) 120mm case fans, Scythe Katana 3 cpu cooler
* OS Windows 7 RC Ultimate 32bit
* a OCCT / Prime95 Stable screenshot (didnt think about it... and shut it off, rebooted, saved settings, and made stable at 3.5Ghz for more economical temp issues... it ran at a constant 54*c at the 3.7 mark.. runs at 44*c at 3.5Ghz)

i will try to get the screenshot as soon as i get a monitor and hook it back up lol. sorry guys

Batmang, try dropping your HT (hypertransport) speed. As of right now you are about 400Mhz overclocked from the stock (1800Mhz). Taking the multiplier down would certainly drop that speed. An HTT (reference clock speed) of 276Mhz may also require some chipset voltage. Have you attempted raising that a tad? I'd also advice looking into adding some voltage to your NB Frequency. 2200Mhz isn't all that high but if you start nearing 2400Mhz then you might want to think about it

Your memory is also 60Mhz overclocked from stock (400Mhz). Try lowering the divider so that the frequency is below stock. See if that helps at all. An increase in VDimm may also be beneficial. Don't forget also you're getting close to the limit of a Ph II with the 3.8Ghz overclock. Is this current OC OCCT stable?

Good luck

Thanks think3r, I've added voltage to the NB, SB, VDDA, HT (tried lowering multiplier as well), and memory. Nothing seems to want to let it boot passed 277. And no way, 3.86GHz this is not OCCT stable. The highest OCCT stable I've hit is 3.6GHz. 3.86GHz will sit in Windows all day, but once the CPU is taxed, it reboots. I've lowered the NB multi and HT to super low frequencies and still a no go passed 277. It might just be my boards max HT, the batch my chip is from is definitely capable of 4.0, finding the right board and RAM is the hard part. I'm just going for max bootable OC, I was hoping to hit 4.0, take a screen, then stand up and clap. lol!

For daily use I keep it at 3.5GHz, the voltage needed passed 3.5 is too high for me to justify it for daily use. 3.7GHz is attainable at 1.55v, OCCT'able however would require 1.6v to be stable. I COULD run it that high, but... electron migration becomes an issue. I'm sure I could get 3.8 to be OCCT stable but that would require some SERIOUS voltage.

This is a 5 min (gotta head to work ) OCCT run at 3.7GHz using 1.56v. 1.55v isn't enough, CPU wants 1.56v for 100% stability. I can run 3DMark and even play games and the CPU is fine at 3.7GHz with 1.55v, but to pass OCCT it needs 1.56v. Check out the screenie. 45C, gotta love water.

Batmang, even if you lower the memory frequency and hypertransport speed you still run into instability issues?

The temperatures at 3.7Ghz aren't looking all that bad. What was the highest overclock you were able to achieve with low Vcore?

Good luck

Interesting thing is that I got it to post and boot up to 3.7 with voltage at auto (14 x 266) however cpu-z said FSB was 244. Prime95 gave a bsod, so I backed down to 260 and same thing until I changed voltage to 1.52V (first try, might check out 1.51V). I didn't try over 266 yet, but is that a sign I won't be able to OC my FSB past 264?


* Phenom II 920
* CPU stepping unsure (cpu-z says 2???)
* Revision RB-C2
* 3640MHz (260x14)
* CPU voltage 1.52V
* CPU-NB voltage unsure, set to auto
* Northbridge clock 2340MHz auto voltage
* HTT link 2340MHz auto voltage
* Asus M3N72-D
* Bios 0701
* Air
* Vista 64
It's hard to say exactly, I'm passed Prime95 for 5 hours and then crashed while browsing the web or something. Probably something in the range of 8-24 hours on blend if you want to be truly sure.

Yeah, even if I lower the memory and ht frequencies, still won't boot passed 277 HT. Highest I could get at stock vcore was 3.3Ghz, but not stable. Highest stable is 3.2GHz.
