Hello to all! new here, but not to overclocking (been oc'ing since the pentium 200mmx days lol). I have been having a weird issue while trying to clock my 550 be. It does 3.6 stable just by bumping the multi to 18x. Nothing else needed. It is also stable at the same 3.6 oc with 2800mhz NB with a +.300 NB-VID voltage bump. Temps are actually pretty good(20-23 idle and 38-40 max) for the stock cooler, but my ambient is pretty low too at ~18-20c. The problem is that nothing over that is stable. I can get to the desktop at 3910 (200x19.5 1.5vcore and various other settings using multi and fsb as well as bumping the NB, and ram voltages too) but it always crashes after a short while. It would seem that being able to get 3.6 without bumping the voltage would leave some headroom. This wont even do 3.7 stable all the way up to 1.5v(in .025 increments). The part thats really confusing is I always get the same sort of crash, but it's not lockups or bsod's-- it looks exactly like a gpu crash with the screen flashing vertical lines and changing colors. Only, my gpu is at default stock settings (catalyst 9.12 drivers).
I know the board can handle high fsb settings. Before I got the 550 I had it running a nice smooth 50% oc with an X2 4050e(2.1 stock)@3.15ghz 1.39vcore and 300fsb with .1 bump to the NB 24/7 stable.

Maybe it's because the board(ma-GA78GM-US2H RV1) is technically not an Am3 board?
Maybe it some catalyst driver issue?
I thought about removing the discrete gpu (HD5770) and trying with the onboard, but that seemed kinda pointless since I also use this rig for gaming.

Running a fresh install of win7x64 if that makes any difference. Also tried it with xp and got the same results, if not a little worse.

Thanks in advance for any help.

Oh and btw: yes I know that stock cooling isn't the best but On all my attempts to run stability tests the temp barely reached 50c at 1.5vcore (most of the time it wasn't even at 43c 1.44 vcore) after half an hour or more. Then always the same vertical lines crash with whole screen changing colors.
few things:

1. It might be your CPU limit. My 550be went to 3.85 GHz and nothing above. And i t5ried everything.......
2. Stock cooling ?!!?! As far as i know it's not wise to go above 3.5 - 3.6 with stock. Get an aftermarket cooler.
3. Overclocking is more stable in x86 systems So you might want to drop x64 and go for x86.
4. Are you sure that are your real temps !? Cause they seem low .......

G.

is there a smaller one you would recommend?

i will up the voltage to 1.34?
all my current voltages are 1.32 apparently.

should i be safe with that?
It fits. I have aprox the same cooler in an Antec 300.

that's really impressive!

have you run any other stress testing apps on it?

The maximum safe voltage for this processor is 1.425v according to AMD. You guys are going off the stock voltage setting for a dual-core not a quad-core. The 965 (for example) is about the same rating stock (1.4 volts) hence the reason why I recommended trying 1.4 volts. Unlocking additional cores may require more voltage. My Athlon II X4 620 is stock at 1.4 volts. Trust me I've tried undervolting the processor but it failed miserably in OCCT in the first 20 seconds of testing. Granted the 620 runs cooler because of it's smaller die size but it's still a quad and requires that amount of voltage regardless. Also the cooler that came with my 620 is identical to what is used on the 550

It's worth a trying. Heck for all we know TheM could be trying to unlock faulty cores...

Good luck

did not do prime95

although i did do better on superPi with little lower OC
realized that faster mem speed matter much more on superPi..


i had made a custom cooler for cooling pwm on that board..but it kind of broke.

will be getting better ram to try higher..
the chip kind of requires a lot of voltage past 3.8GHz
i have not tried OCing with only 2cores though

Is your Delta fan okay? How many cfm's is it and is it louder than the graphics card sometimes?

I'm going to OC some more today, since my temps are low (30C Idle 3.8ghz). Hope to see some promising results!

the delta is being used now, wasnt there while that overclock.
the fan is louder than my ceiling fan while at full speed.
im using the delta at 2000prm for both exhaust and cooler...at that speed they are a lil quieter.

about gpu fan noise, im using the stock fan (that small red one) at 2k rpm..it doesnt make any difference at 100% because of the 2z 120mm 90cfm sunbeam fans... although if you want to compare noise then the deltas are as loud as that gpu fan at 100%..or even more i may say.

the deltas are rated 120cfm at 2500rpm.. max speed at 12V is 2800-2900rpm..
max possible speed is 3500rpm as per product spec sheet.
the fan is able to keep the chip at 2-3c above room temperature at idle.
i have just started using TX-3 paste.. although i see no difference in idle temperatures as compared to TX-2..
