fx 9370 @ 5ghz very low cinibench score

So after a lot of testing with occt, it seems that 5ghz just wont run right on my board. After I dropped it to 4.82 ghz cinibench did a 743 score. I did do some changes to memory and up'd it to 350ns since I'm told that allows higher clocks. When I ran occt at 5ghz, It seemed it was halting on memory issues. Timings are 10 10 10 30 34 350ns. I know this cpu can do 5ghz no prob, just wondering if it could be a northbridge or hypertransport speed issue. NB is at 2200 and HT at 2410 @ 4.82 ghz. Any ideas how I can get a nice stable 5ghz, I feel it may be a memory issues holding me back. It is 1886 ram running at that speed. Currently doing only a multiplier oc and not fsb oc.

Edit 1* Just a note, when I had 5ghz running stable without doing a cinibench, I ran watchdogs on max with two 770s oc'd and it ran for about 45 mins before pc halted. Only ran it once and been fiddling with oc since. My 780 watt psu seems to be handling power usage no problem so just cpu stress testing shouldn't be making any terrible demands on the psu.

After getting another stable 5ghz clock it once again has a low cinibench score. Went from almost 800 cinebench @ 4.8ghz back to 357 @ 5ghz

Thanks for the responses. Gonna be some delayed posts from me due to life. I've managed to get a stable 4.875ghz oc with the cpu so far. 1.536 volts and it hovers just lower or at that. HT at 2331 and same for NB. I upped my rams voltage like you said. It is stock 1.5 volts but I know it can handle up to 1.6 no prob. Had it at that for a long time in old build and never had heat issues. Now what is the max voltage I can go for this cpu? I am on a h100 in a high airflow case in a cool basement so processor even under bench doesn't even hit 44c. Hell old 1055t overvolted to hit 4.1 ghz only ever reached 46c in this case. Now with this crappy gigabyte board, I have noticed that voltages I set things to dont actually seem to stick. I put ram to 1.55 and it sits at 1.523 in bios. Cpu is the same as what ever i set it at doesn't seem to stick. There is LLC setting in my mobo. The settings are low, med, extreme, normal, and auto. Currently have it set to normal as extreme volts cpu really high and med is kinda low. Was gaming at this current setting last night for several hours no prob. All though right before I went to bed it froze. Checked the northbridge while it was still froze and damn thing was burning hot. I had it volted up but turned it back down to normal so that should stop some of the heat. I'll be on and off this forum for the next few days with help from you guys in trying to hit that 5ghz goal. I can game at 5 ghz but not for a very long time and cinebench works like crap till I hit the 4.875. So much crap this past weekend with work and my uncles funeral. Thanks for any advice given.

I only have one LLC setting in my mobo, and it only seems to affect cpu as far as I know, could do more. So just set it to extreme?

So I'm doing some burn tests with prime95 and the oddest thing is happening. The temp is sticking right on 40c and I'm showing 100% cpu usage, but only 2 cores are really doing any work. 2 will be on test 6 when the other 6 will barely be making it to test 2. Something is causing the cores in the cpu to just work slow. I wonder if its the cpu unlock feature in bios. Knowing gigabyte it's prolly doing something stupid. This cpu should be getting way hotter than 40c, and each worker in prime95 working at about the same rate. wtf is going on?

I cant seem to figure out this damn motherboard. God damn is it a pain in my ass. I seem to have absolutly no control over voltage what so ever. The LLC settings for this board are confusing as all shit and the user manual doesn't even mention it in it even once, even though you can see a pic of it. Even if I set voltage to like 1.7 it sticks at 1.5 and durring stress test it drops to 1.488. If I set LLC to extreme it will use higher voltages but I always get a black screen of death. I have never had so much trouble with ocing before in my life. Any clues as to whats going on?

So I've managed to get to 5ghz and get cinebench to run with an almost 800 score. It wanted more power and with LLC turned to extreme I'm able to get voltages higher than 5.3. Had to turn up northbridge by a slight bit to get the CPU voltage to kick in. It’s really odd, I set CPU voltage at 1.478 and it idles at 1.500 and goes to 1.560 during stress test, but it's finally going higher. I'm currently trying to get a nice stable 5ghz, but not raise my NB voltage any higher as it gets hotter than hell. Don’t have a infrared temp taker so can’t tell what the temp is actually hitting. Currently raising other voltages ever so slightly such as cpu/pcie/pll but a smidge and hypertransport voltage ever so slightly. It’s getting more and more stable and can almost make it through a complete cinebench with no issues before locking up as usual. Ran out of time before I could test further before work. Another oddity is I set ram voltage to 1.75 and it holds at 1.6 which seems to be the sweetspot. That ram I have must be damn good ram because it never gets hot in the slightest, even when I used to take it to 1.6 volts, highest I've ever had it. When I get off work I'll try more.

As for cool n quiet, of course I have that crap off. I turned on HPC (High performance computing), it seems to make it more stable at higher voltages and I turned off that APM crap as it seems to slow things down during stress tests.

I noticed once I managed to get a functioning 5ghz clock that temps went up really fast. H100 wasn't kicking in fast enough and actually got a beep for a 60c warning I have set in bios and reset when that went off. Unplugged the fans from the pump which auto manages fan speed based on temp (it would react to CPU temps too slowly) and plugged them directly into the mobo(60c was due to hitting over 1.589 – 1.6 volts, crazy high). There loud as hell at max but during stress tests at 5ghz 1.560 volts it sticks right on 50c and might see a 51 or 52 after a long while. This CPU definitely gets hotter than my old 1055t that was volted to 1.45 volts 4.1ghz, and I thought that thing produced some heat. It sure as hell heated up slower than this 9370 does. Temps in speedfan bounce around like mad from as low as 9c to the bench temp.

The vrm's get hot on this board and today I'm going to borrow my cousins infrared temperature gauge to find out what they’re sitting at. Oddest thing with this mobo, even when I had CPU voltage set high, cinebench would work like crap and even at 5ghz, would stick to a 1.53 volts max until just a smidge more voltage was added to northbridge. As stated before, I recently upgraded from a 1055t at 4.1 ghz and a 990fxa-ud3 rev 1.0 board. I had to due to the 8350 being the best CPU supported by it. That revision was so much easier to mess with overclocks in than the 4.0 I have now. Don’t believe it had a LLC setting in it but damn did it take a 2.8 ghz locked 1055t to 4.1ghz no problem, sad thing was it downclocked my nice 1886 ram.
