Phenom ii x4 955 and ram oc fail.

I'm having problems oc'ing my phenom ii x4 955 to 3.8ghz, and ram to 1600 which it should by default.
The ram is Patriot Sector 5 2x2gb 1600mhz ram. The ram apparently only runs at 1600mhz with intel lga 1155, but i ignored the warning and went on and bought them since they looked nice and I figured all ram should work with either amd and intel. Is there any way I can get the ram to 1600 just by messing with the settings?

I've been able to keep a steady overclock on my cpu @ 3.8ghz with a 1.4v, but just last night my computer went into fail mode, and started blue screening as soon as i messed with the ram settings and I had to set everything back to default/auto. sooo... Help? :(

it can run at 1600MHz, but it just isnt as easy as XMP

just make sure not to raise your ram much past 1600MHz, thats where ive always seen issues, and you should be fine

I try to run the ram at 1600mhz, with auto timings and all, and I still get the blue screen. Also, I haven't been able to raise my cpu clock from stock @ 3.2 without blue screen. All I do is raise the voltage by a little and raise my clock speed to 3800 and i still blue screen, am i doing anything wrong?

What is the highest volt i should go for 3.8ghz/4ghz? I have the zalman 9900 for cooling.

I recently tried to over clock my cpu back to 3.8ghz but it wouldn't be stable no matter what voltage I fed it. I'd be able to load into windows and play a game for 4 minutes, then i'd blue screen. Help? ):

I have a Phenom II X4 C3 stepping prime 95 stable at 3.9 GHz with 1.375V @ 26C idle/56C load. Anything above that requires a big voltage increase, but my temps are already pushing it so I've left it alone.

what are your temps?

OP may have a C2 stepping phenom II which would limit his OC much more

My old Phenom II x4 940 max OC was 3.8ghz, Regardless what I did it was not going past that.

Keep the ram as close to 1333mhz as possible, and the CPU-NB close to 2000mhz or 2200mhz, give the CPU-NB a lil more juice, it can help stable the OC. Keep the HT Link at 2000mhz.

Also how are you OCing the chip? Most AMD boards I found don't like to go much above 230 FSB with the Deneb core, not sure why. So you might have to OC with multi and some FSB.

this is what I got on my 940 to get 3.8ghz, but note that the 940 base clock it 3ghz and was using DDR2 800mhz.

I have the RB-C3 phenom ii x4 955, have no clue what the RB means, but I can't even mess with my ram settings other wise that would cause the blue screen, but I usually just increase the multi, and when it won't boot i lower the multi by 1 and increase the voltage by .125 or w/e the minimal volt increase is. I also have asrock extreme 3 870.
I was able to play non stop sense march 2011 @ 3.8ghz but recently it hasn't been wanting to go over 3.4 without crashing.

Also, I'm using a zalman 9900 cooler. So I shouldn't have issue's with heat unless not changing the thermal paste in 6 months could lead to overheating?

Oh and, I don't know if it's my mother board, but I'm unable to use programs to tell me the temperatures of my cpu.

Sometimes its best to OC with both Multi and FSB, BTW what is you temps at 3.8ghz 1.4v? Phenom II's don't like anything over 60c, start seeing instability at 55c. You might just simply need more vcore. Don't go over 1.55v, you might need 1.45 - 1.49v for 4ghz, they all OC different.

So you might need a bios update, Go here and is will show you how, There is an instant flash utility that ASRock uses witch is vary simple to use, just need a USB flash drive to put the bios up on, then in the bios there should be an option for instint flash, click that and fine the USB flash drive and follow the onscreen instructions, Might even allow you to OC better with the update http://www.asrock.com/mb/AMD/870%20Extreme3/?cat=Downlo...


PS. You can also do it with in windows, but I don't trust it.

I've already flashed it to the latest bios. I did it a couple months ago.

edit: OH also, I just went through my bios a few minutes ago and was able to boot into 3.8ghz, I left the cpu voltage alone, and just increased the nb by it's minimal amount. I don't know if it's stable yet, I'll run through bf3, arma 2, and sc2 to see.

Thats strange, HWMonitor doesn't give temps? Like at least CPU Core temps?

Yeah, I've downloaded 2 differen't monitors, and neither will give me cpu temps. they stay @ 0.

Hmm, go into the bios and set the active cores to auto and turn the core unlocking off, I think that will make the temp set at 0, The 955 wont unlock anyway.

31c idle is good, Play a game with that open or run prime95 and see what the max temp will hit.

Ah! One problem solved, Ucc was enabled. and I'm guessing that was the culprit with the temp readings.

just finished a benchmark in arma 2 and max temps with 42C, with core volt spiking to 1.440. No crashes yet.

Not bad at all!

Im not sure if your 870 extreme3 is like my 970 extreme3 but I have a option called LLC - Load Line Calibration, Mine said to enable it only for AM3+ CPU's and disable it for AM3 So I disabled it for my 1100T (AM3) and I was having issues with it staying stable. Enabled it and my clock was stable but my volts do go up a lil more.


Edit, 51c is not bad, don't let it go above 62c and you should be fine, Could always try hitting 4ghz, it should hit 4ghz.

Interesting. But no, I don't think it has LLC. At least, I haven't seen it. and I might try for 4ghz when I know I'm going to be replacing this mobo/cpu which should be next year.

Now for my ram problem... If i take it off auto, It won't let me set it to 1066/1333/or 1600, it has odd numbers like, 1045, 12xx, and 14xx. And when I go into timings, to set it at the recommended, 9,9,9,24 it crashes just like it would with my cpu.

I don't have any mem test software so I don't know if the memory is bad, but it's ran fine at all auto settings.

This is the timings that cpu-z shows me.

I figured out the reason why it was giving my odd values for the ram clock, I had the overclock mode set to cpu and pci async. I just set it back to auto.
