790gx paired with kuma. overclocking help

60C is fine but I you can't go wrong with an aftermarket cpu cooler if you don't already have one. Can you tell me where to get that oc program you used? Its tight.
 
Nah man this is all stock. but i do have 3 fans in it: one rear 120 and two 80s on my side panel.. the program came with my motherboard. im not sure if asus releases it as a download.

i set my bus speed to 215. my cpu was at 3225 and my comp just restarted when i got to my desktop, my temps were only at 45C, why wouldnt it be stable?
 
If thats all she wrote, the stock cooler is not much for overclocking. Plus raising the bus bumps up the memory and HT bus also. Try bumping back you HT and Memory or bump up your N/B and Memory voltage.
 
ok ill clock my ht and memory down. ill go through some trial and error with the voltages and post my results.

im kinda interested what i can get out of the processor with the stock cooler actually
 
Its just hard to believe that a Asus 790GX board would kill the X at 15! Are you sure? Make sure it has the right bios update.

well, look what i found out




Apparently they want me to revert to software after 15x. That program lets me go to 20x which is kinda cool, good bye bus clock.

But also if i overclock any higher, my comp just reboots during a stress test. No warnings no bsod no post errors, i dont get it. could that be my psu buckling under the load or what?

its not right i used to have the same asus 790gx multi goes as high as you need.. are you using ai suite to overclock? if so install AMD Overdrive much easier just a bump of the multi Bam!

thats when you bump the voltage a bit
 
When ur pc shuts down "randomly" after a high overclock it is because there is not enough cpu voltage. Bump that up if you want to oc higher but be careful.

tried 1.4625 @ 15.5x 3110mhz.. boots and runs perfectly. but second core fails after 10 minutes on prime95.. my temps are at 58C load i dont know why its failing.. should i go higher on the voltage again? would it help volting up my motherboard?

im not sure how to get my cores stable when my temps are fine.. wtf
 
for reference, at 1.43v i'm at 3.2ghz. I'm using aftermarket though, used to be AC Freezer 64 Pro, now it's Zalman 9700. When I'm using the Zalman fan (too loud for my tastes) it was 18c idle -38c 100% load.
I also had to download and flash my BIOS to a higher version on my MSI K9A2 Platinum, because my CPU was only recognized at 2.2ghz and a 1000mhz HTT (versus stock 2.7ghz and 1800mhz for Kuma)
My maximum stable was 3300mhz (200*16.5) @ 1.52v. I could run 3dmark06 up till like 3350mhz though it failed Orthos after 10 minutes or so. My PSU could be holding me back (+12v34A @ 550w, with 2 hdds, 3 Antec 12cm fans, 1 Antec 22cm (or w/e big one is) fan, Radeon 4850, CPU, and Optical drive)
 
so could the reason my second core is failing be my psu?... because my psu i think is kinda weak (12v16a @ 400w).. heres what i get:

when im at 15x prime95 passed for 8 hours. at 15.5 prime95 fails after 10 minutes only second core....

dropping the muilti to 14 and i got my bus to 214= 3025mhz prime95 passed for 8 hours. when i put my bus to 220: 3108 prime95 fails after 10 minutes only second core..

its like my chip is limited to 3.0ghz.. wtf
 
There's a REALLY good chance your psu is holding you back.
Depending on your video card and other components of course, but with only 16a on a +12v rail it's a really good chance you're being held back. I feel that even I'm being held back with the dual +12v rails (16a+18a).
Since it's just your second core that fails, not the system, it doesn't sound unstable because of the clock speed or heat, but the PSU. My overclock at 3300mhz had temps near 22idle/44load, but 3333mhz wouldn't even go through Vista's startup all the way (though temps stayed the same.)
 
Like said. Not saying it is it, but running a P/S with a single rail with only 16 amps. is not going to help. Especially since the system is just restarting. If it was just the overclock it would give you more in the line of the big blue screen ERROR or would just lock up.
