... and 1.6V Vcore? Are you watercooling that bad boy? That must be a very quick machine.

Yes, I did that last night outdoors (-14C ambient temperature) with my small water cooling system.

Indoors and using safe voltages the CPU seems to be capable of 4.6GHz - 4.7GHz or so and the CPU/NB 3.3-3.4GHz. :-)

I'm trying to assimilate a lot of the information gathered here over time. I certainly recall the points about the M2N32 being an excellent OCer.

Didn't realize the M2N32-SLI Premium used the 570 and not the 590 chipset.

How high can you run your 955BE for CPU Frequency setting?

Yes, the M2N32 boards are truly amazing boards, especially compared to more modern motherboards. For Example my Crosshair IV Formula really struggles with HT reference clock frequencies above 320MHz, but the M2N32 boards have almost no limitations at all, it is only the CPUs that limits how far I can push the HT reference clocks.

No, CPU-Z is wrong for some reason, the M2N32 Premium does have the nforce 590 too.

I don't actually own a 955, but I own a 555. With that chip I can only clock the HT reference clock to about 285-300 or so, depending on what cooling I use. Beyond that the CPU/NB becomes too unstable and the system refuses to boot.


I did some further testing with the Sempron and I was able to get it 100% stable at 4.6GHz with 1.47V vcore and CPU/NB at 3.36GHz. :-)

I misread your sig. I was hoping it was a 955 because I was looking to understand if it was the Deneb's memory controller that was limiting the FSB speed. I can only conclude that is the case since you've proven it works with the Sempron.

What processor do you run on your CHIV? Are you actually able to run the FSB up at 320?

Going back to the Sempron for a sec, how did you decide on that processor. Is that the fastest processor you can get for the M2N32 that will run the FSB up those speeds. What is real life performance like, and what would an aircooled version of that run at?

I currently use the 555 with the Crosshair IV Formula (my sig needs updating).
On AM2+, AM3 etc motherboards you have an adjustable multiplier and adjustable voltage for the CPU/NB too. Since the 555 is Black edition CPU I have only increased the voltage voltage for the CPU/NB to 1.3V and set the multiplier to 14, giving me a CPU/NB speed of 2800MHz. Compared to using the 555 with the M2N32 Deluxe board and running the CPU/NB at ~2300MHz, the system feels a little bit faster, but the difference is not very large.
I suppose that I at least in theory could clock the HT all the way to 320Mhz using the 555 to if I wanted to though.

Well, I bought the Sempron mostly because it was very cheap and because it is one of the very few AM3 CPUs that is available for sale here in Sweden. I was hoping I would get a good overclockable & unlockable CPU that could use to upgrade one of my fathers computers. I really did not expect to able to clock the CPU all the way to 4.6GHz (I was only hoping for at most 4.2GHz).
Compared to a Phenom II running at lower clock speeds the system feels faster and more resposive doing certain tasks, but a Phenom II still feels a bit faster in other situations thanks to the large L3 cache.
I might get 100-200Mhz or so lower clock speed using low end air cooling. I'll get back to you on this though as I intend to test this soon.

There is one really strange thing about this Sempron though (compared to my older Athlon IIs & Semprons). When I lower the memory multiplier (to make up for the increase in HT reference clock) the NB/IMC competely refuses to boot with some of my memory sticks. Other memory sticks do work, but I cannot overclock the memory very much.

If you intend to upgrade to a AM3+ motherboard and move your CPU to that system I really recommend that you buy a cheap Sempron or Athlon II to use with your M2N32 motherboard. :-)

Hey Gyro, Gr8, etc. I'm back once again.
I just bought a new PSU and a new GPU

Here's my new cpu-z:

2252833.png

I just installed the new PSU and bfg - gtx 275, upon boot I decided to check the bios just in case and as I suspected, my settings were reset. I set my voltage and all that back the way we discussed:

CPU Voltage: 1.3275v
CPU Multi: 15x (running @ 14.5)
CPU Freq: 250 MHz

CPU/NB HT Volt: 1.25v
HT Multi: 4x
Ram: 667 (brings it to ~840 MHz with the increased freq/multi/cpu-->nb)
NB Volt: 1.30v

Ram Timing: 4-4-4-12-Auto (24)

All seems to be working good. Just checking if I need to un/re-install my nvidia drivers.. But Win7 "found" the card and installed it properly and it seems to be working so I guess not.
Anyways, I absolutely love my new PSU. Got it off NCIX.ca (http://ncix.com/products/?sku=62391&vpn=OCZ-ZS550W&manufacture=OCZ%20Technology&promoid=1315 for an amazing price.
My old PSU has been giving me amazing results since ~ '04/'05, which I think is amazing since I never turn my pc off either. So that's much more than the typical life span of a PSU from what I've read.

Anyways, that's the update. Any suggestions or tips/reminders of anything I missed feel free to let me know. Otherwise, thanks for your time. thumb.gif

Lots going on here. Let me temper this by saying I'm not unhappy with the setup I have now. But I don't want to leave any speed "on the table", which is why this topic interests me.

What it seems to me is that the Deneb family can't push CPU/NB speed past 2000MHz reliably, although I've seen for myself that I can push CPU Frequency past 250MHz under certain conditions. I don't have any other data points to compare to. But there may be more to this I haven't figured out.

Since you could, why don't you? wink.gif

I'm sure I've seen this problem myself with the Corsair DRAM I have. I'm not really interested in spending any more money on DDR2 RAM though to test this out. I had some older .5GB sticks that I used to push CPU Frequency to 300MHz I think, so that's one reason why I subscribe to this idea. I just don't understand why the IMC throws up with the other RAM I have.

Sure, sounds like a good idea. The CHV is something I'm eying but I want do some more research on cases and RAM since I'll likely be purchasing all those items together. I just learned recently that my 965BE can only support 1600MHz speed on the memory interface. Eventually I guess I'll have to upgrade the processor to one of the newer Bulldozer CPUs.

My only comment on all this is that I recall you said you had gotten PMT to work for your setup. PMT is unable to control Vcore and CPU/NB voltages independently on AM2 boards. The governing voltage setting is CPU/NB. Use CPUZ to check/confirm what your Vcore is really running at. I'd probably bump CPU/NB to 1.3V or a little higher to make sure you're feeding enough volts to the 955. Another choice is to use Vcore Offset setting in BIOS to increase that voltage and keep your CPU/NB voltage lower if you choose. I use the former setup myself.

I don't know much about your GTX 275, for instance whether or not it is SLI capable. That's the one thing about the M2N32 I really like, ability to run two GPUs @ 16x. Really makes a noticeable difference when gaming.
