help with oc'ing my FX

[Matt82]

My spec is as follows:

FX4130 BE
Gigabyte 970a UD3P
Corsair CX600M
4 x 2GB Corsair XMS3
Artic Cooling Freezer 13 CPU cooler

I have managed to get the FSB to 260 stable on a x17 multi but when i go any higher it becomes unstable. vcore is at 1.525v. NT and HT are both at x9 multi (2340mhz) with 1.3v going into each. i think dram is on 1.55v (stock is 1.5v) with the memory frequency at around 1400mhz (a touch lower I believe). CPU temperature never goes any higher than 50-53 when prime is running or playing BF4 etc.

Now, I cannot find any OC guides on this specific mother board so I don't know if it is the mobo limiting me atm. With the multi on x17.5 I get 4.55GHZ but prime fails (usually on a single core) after 4 hours or so. any ideas on how to get this stable and potentially hit that 1ghz club? (please do not recommend turning FSB down and cranking up the multi).

i think i will look for a different piece of software as well.

i'm kind of surprised at the lack of responses considering this is an overclocking forum, lol...

I think that 4.4GHz on that motherboard is quite good for a 24/7 OC. The bulldozer core does not OC quite as well as the PD and it is a 125W TDP similar to the later 6/8 core processors. However your temps look good, is it throttling under load?

Anyway I think you are going the right way with FSB (bus clock) maxed and then using the multi. If you drop the bus clock a little to get a higher multi, is this better? I assume that the ram you are using is 1333 rated? Around 250MHz will bring the memory to around stock on your current setting, allow 2500MHz HT and NB and 18x is 4500MHz on the CPU.
Ensure plenty of case ventilation and particularly around the VRM area behind the CPU. Try to minimise the vcore a bit, and adjust any LLC settings to reduce vdroop if possible.

Good luck, andy.

thanks for your reply. could i ask where you got that 4.4ghz is good for this mobo? i have looked everywhere for other peoples results/a guide on this board but with no luck! i have up'd the multi on NB and HT to x10 and running more tests. if i can get it stable as it is i may just leave it. for under £90 i am pretty happy with the results. although i really want to hit that 1ghz club. maybe dropping the FSB and cranking up the multi is the way forward?

Well I got 260 stable but have lowered the bus and turned the multi up. I really want to hit 4.8 or as close as possible to it. In all honesty I do not think the 970 boards are good past 4.5-4.6ghz as they start to become unstable. I will continue testing and let you know how I get on. Any further advice or ideas would be greatly appreciated
