This is my first venture into overclocking, take a look at these screen shots and tell me what I should be working on. I know it's pretty mild compared to some of you guys, only about 7-8%. My memory well default to 1866 IF I run two sticks (8mb), but with 16mb it defaults to 1366. 1696 is as fast as I have had all 16mb and be 100% stable. Prime95 torture test has been running a couple of hours now and temps remain as in the screen shot.
Ok if you have ram that runs at 1866 and when you ad the exact same ram to 16 it defaults to 1333 ?
then it has to be one of the memory sticks that are no good should run a mem test
even if they default back to 1333mhz you should have a option to choose it's rated speed im not sure if you mean when you have one set it just goes to 1866 or you have to adjust them to 1866
anyway you have done a very mild oc that probably would not need a voltage change max turbo on FX4170 is 4.3Ghz you are running 4.664Ghz hardly a need for a voltage change the chip is already set pretty high so an increase of 300mhz won't hurt a bit I don't think and if you ran prime with no errors then you should be fine
Looks like a solid OC thus far
It's a limitation of the cpu, the 4170 well run 1866 with just two sticks but defaults back to 1366 with all four banks filled. AMD has this info buried pretty deep on thier web site. I may do some bench marks with just two sticks to see if it's worth loosing half my ram. I did have the cpu to 4800 but was seeing random errors. I have not played with cpu voltage...yet.
Been playing with the GPU today, this 7770 does not like a lot of OC. I've read that some are getting 1250 core and 1300 mem. Best I can do so far is 1125/1275 and that's with a +10% voltage. Upping the voltage brought the temps dowm. I would push 80C with FurMark and now it's 72-73C with the same fan profile.
Thanks for that link Britten. Currently I have the 16mg (4X4) OC'd to 848X2, or 1696. This OC has been stable through several torture tests this past week. I'll keep working at this, I want to see the rated 1866 with all 4 sticks installed.
When the memory settings in BIOS are set to default is when I have the expected 1866 with 2 sticks and 1366 with 4 sticks.
Question about the GPU, when I upped the voltage 10% I saw a reduction on full load operating temps, is this normal?
I have something similar with my DDR2 8 GB RAM 800mhz G-SKill but should run at 1066mhz, do to the same limitation of the CPU and MOBO. What I did was to make sure I had a CPU that could handle that and then OC my RAM in the BIOS using CPU-Z for the timings and voltage. I've been running the RAM at that for the past year. What a difference it made doing so.
That's my next step. As I recall changing the fsb changes several other settings.Also if you really want to get that 1866 going to have to sacrifice some more multiplyer and bring it up fsb
