I need my USB sticks to flash.....ahh the joys of tuning my ram all over again...people won't hear from me for another 3 days once I flash.......

1.3 is awesome, 1.37 is a little better still

You need to flash asap

I'm gonna take this advice Saturday.

I'm on 1.3, no problems with a USB keyboard. I flashed using a bootable USB stick.

Currently I'm dialing in my CPU OC, it wouldn't boot at 4GHz even with 1.55 volts so I backed off I really wanted 4GHz. I have a suicide run at 3.914 which only took 1.46v to do, so considering the giant jump of volts it was taking to even get it to show the windows load bar for a second I think I'm at a wall on this chip. Unless there is something to tinker with more in the bios that I'm missing (easy for me to do, I'm a noob at this lol).

Max safe 24/7 volts on these 955's is what, up to 1.5V? Less? My VID was 1.35. I'm at 3.817 with 1.47V priming at the moment, it may take 1.5V to be fully stable.

*edit* I'm at 1.5V now for 3.8GHz, priming. So far, it makes it through a couple tests on blend or large FFTs then BSOD.

I'll post some pics later....

did u try setting acc to "auto"...
i have to set acc on auto to be stable at 3.8ghz with 1.48v (cpu-z reads 1.45v).
i can even run occt for about 30mins at 3.9ghz before i get that bsod.
suicide screenshots of 4ghz are possible, but nothing else at that speed.. unfortunately.

Make sure your memory and nb are stable before clocking the cpu, I actually had a hard time getting mine to run stable at stock speeds! Oddly mine only wanted to run stable with a high nb speed (2800mhz) and a big bump in PLL voltage. Getting into windows with the multi set higher than 20 fails every time but I managed 4.218ghz (valid) by raising the bus speed and 4.44ghz without a validation. With vcore it seems that less is more sometimes with these chips, find out how low you can run prime stable at stock speeds and you might be in for a shock. Mine runs stable at 1.1v for stock and 1.4v for 3.8.

What memory and speeds are you running anyway? I have a 2x2gb kit of ocz running 1600mhz 7-7-7-24 1T @ 1.95v and have a set of 1800mhz cas 8 crucials coming friday to try a little bus clocking with. I tried running the low speed tight timing bit as people have said to but the performance hit was really bad... 6-6-6-18 1T 1333mhz gives far worse results than 7-7-7-24 1T 1600mhz.

Flashed to 1.3 last night. SNiiPE DoGG was right, flashing with the M-Flash utility in the BIOS with a USB stick was easy as pie. Only took about 45 seconds. Will toy around with it tonight to see how it performs.

Was toying with these two configurations some the other night on my CAS6 1333 Reapers. Integer performance difference was rather negligible, but I didn't do much testing with bandwidth differences as I was still feeling for stability. Which tests did you run to measure the differences?

[hellcamino]

Everest memory benchmark and much more informallly, gaming performance.

Hellcamino - how big a bump in voltage did you have to put into PLL?

Did you use PLL to gain stability in your CPU Overclocks or NB?

I bumped the PLL just trying to get it to run stable at stock speed initially! Small fft's would fail in under 2 minutes at stock with PLL left on auto, I worked it up to a bit over 2.6v IIRC. I can't check the bios until tommorow as I have the machine torn down to put together a real lcs for it. I did notice that it took less vcore to run a given speed afterwards and the cpu-z reported vcore was much closer to bios setting with less apparent sag under load.

Hellcamino,

Thanks for the info. I belive stock PLL is like 2.4 ~ 2.5v. Whenver you get a chance to get the info, that woudl be cool. Anything that can lower vCore is of interests

Thanks again.

That should be tommorow evening as I am waiting only on a pump, everything else is ready to go again on it.

Everything was solid at stock speeds. I put the NB and HT link at 2400 and made sure that was stable before I started on the CPU. Good idea on the PLL, I have no idea what that voltage is for but I'll mess with it!

Once I get the CPU solid I'll play with ram clocking some more. My set doesn't seem to take to 1600 too easily though. I have G.Skill F3-10666CL7D-4GBPI. I wanted the OCZ reapers from newegg that were CL6 and cost like 65 bucks, as I knew those were some good d9s, but they were OOS when I ordered and I had to order then if I wanted the "open box" (new) gd70 for cheap.

Well upping PLL has stabilized it a little bit, it makes it through test 4 or 5 on prime blend with vcore at 1.5 (anything lower and instant crash starting prime) and PLL at 2.582, but then ends up with either a BSOD or a reboot. That seems a bit off to me, I figured once it was stable enough to run some testing I'd figure prime would give an error before an all-out crash.

Still tinkering...

[hellcamino]

Mine was doing the same thing before I made sure that it was prime stable to begin with. Try more PLL voltage.

[Sparky]

how much is safe? 2.602 got me a bit farther but still rebooted on me.

[hellcamino]

FIIK ? I have mine at 2.68v I think but tbh mine is a secondary pc, if it would oc worth a damn in 64 bit I would run it as my main gaming pc but it hits a wall quickly. I will give the 64 bit one more try but I'm not holding my breath on it working well.

[Sparky]

Well I set to 2.62 PLL and 1.51 vcore.... if this fails, I may start from scratch and run my ram/NB stability testing all over again.

I knew going in that I was probably going to get an ok chip not a great clocker, my last CPU I bought that overclocked really well was my opteron 165 and that was only because I knew what stepping to look for and paid a little extra to get it

*edit* made it through prime blend tests 1-9, started test 10 and a bit later puked out a BSOD. Sigh.

[TurboDiv]

What is that 64 bit wall ? You mean the Phenom clocks less in 64 bit windows ? That doesn't make any sense...

[hellcamino]

No, it just requires more vcore to do so and run stable apparently. The only actual wall I have run into has been when attempting to exceed 20x multi.

The wall will come down to cooling from what I have seen so far.

Any CPU is like that... 64 bit OS is more stressful than 32 bit OS, since it uses the entire CPU. 32 bit like XP doesn't quite use the whole CPU so it is easier to get a higher overclock on 32 bit XP or Vista than 64 bit.

I never noticed this with any of my intel cpu's, I am guessing this is due to the difference in the way that intel and AMD handle instructions for 64 bit?

Nah I noticed it with my q6600. 3.4GHz 1.45V in XP 32, but when I went to 64 bit vista I could only do 3.2GHz at the same voltage. It was going to take more than 1.5V to get 3.4GHz back again.

I've got my 955 back at stock, CPU NB and HT are at 2600. Going to run prime overnight to be sure NB/HT are fine.

I never noticed tbh, I tested my Q6600 and my X3360 many times and they always seemed to need the same amount of vcore to run at a given speed, I used XP 32 - 64 and Vista 32-64. Running Vista 64 seems to involve a lot of BSOD's at just above stock speeds (3.5-3.8ghz), I haven't tried running XP 64 yet on this system. How does this platform handle a pair of 4870X2's...Anyone?

[TurboDiv]

Now i can relate to the whole situation.. My E6600 in the signature used to be clocked at 3.32 Ghz in Win XP 32bit prime stable for 48 hours, but as soon as i moved to Vista 64bit i noticed that it wasn't stable anymore at 3.32Ghz. At the time i thought it was simply some dust accumulation on my cooler which might have resulted in higher temperatures so i lowered it to 3.28 and forgot about it. Than the next thing i noticed was that Intel Burn test 64bit was "advertised" as the more demanding test for CPU stability than the 32bit test. It all kind of makes sense now...
