post #47741 of 67694
Well....

I'm working on my review for this ASRock 970 board, and also of the 8300.
I'll have it done for you guys some time this week.

I won't comment too much before then, because I am still learning both of them.

What I have found out, is that I underestimated the heat this chip would generate, even under mediocre voltage, and will definitely be looking for a cooler this week.

I will also add that I do not see how this board could possibly be rated to handle the 9590... It won't hold voltage stable well enough, and the vrm sink couldn't handle 1.5 volts even if it did.

I have added some fans that have helped quite a bit, but with hours of prime I see what looks to be either a socket, or VRM reading of over 80c. I have verified this in hwinfo also. Mind you, I can clock the chip to 5ghz on 1.45v but once the vdroop occurs, and voltage goes below 1.38, it completely loses stability. I am trying to determine why this board offers no llc control, or if it does somewhere in the bios,and I'm just missing it?

All being said though, this was all totally expected @ $76, and for the money this is a good,but by no means great board.

Once I get a better cooler, and find a way too reduce the socket temp, I should be able to land a solid 4.8+, but for now, 4.6 @ 1.35v will have to do.

As for the 8300.... Hmmmm
Let's just say I finally understand what everyone has been saying in regards to coming from thuban...
On paper(benchmarks) my x6 @ 4.2ghz did just as well as this chip or better,even at 4.6 (except cinebench), but in real world usage, including gaming and everything else you actually do on a computer, this fx is noticeably superior.
The value at $99 is spectacular. I can guarantee that on a kitty or a crosshair, or maybe even a ud3, with an h80 or better cooler, this chip is definitely a 5ghz capable stud.

Thanks. IBT Max 20 Runs was stable at 9-11-11-30. I'm thinking about going 9-11-11-29 to see if that is stable also but I feel like calling it quits for now as its almost 1am and need to wake up in a few hours.

I had never heard of this, and it seems like it would be usefull.

On intell CPUs i've seen single core boost
.

Never heard of it.

I said I've never heard of it so far, The guy might be BSing or he truly believes he got this working. Whether it's true or an illusion is another thing. For Intel their turbo works in a way that it speeds up it's cores depending on how many cores the load uses. So 4 cores gets a minor boost, 3 cores gets a slightly higher boost, another higher boost for 2 and a single core load will have the highest turbo boost. I don't think AMD's Turbo boost works the same way from my memory. Might be just a X amount of boost for all cores and then a higher x amount of boost for half of the cores. It's possible to disable all cores except one and OC it significantly higher but not sure about the turbo boost for 1 core only. Even for 1 core I would think it needs a significant voltage boost, again not sure about that either just a guess.

If he's truly getting 1 core to boost to 6.2GHz then ask him to upload a screen of a different program that can monitor speed/temp like AMD Overdrive, HWInfo, etc

Yeah, I thought it worked like that as well. Either stock, full boost, or half boost at double speed. Intell does have that nice 50% single core boost on a few chips, which is really awesome. If this did work with amd chips, my guess is it would have become common knowledge by now.

Yeah if this worked then it would be commonly used for games that used only a single core (old games or recent single threaded games) without having to disable the rest of the cores completely in the BIOS.

@Marmota

iirc it is possible with AOD ( AMD Over Drive )

also might be possible by editing p states but i am speaking from my bum on that one .

I put ram back up to 2400 and increased DRAM voltage because I noticed that before, even though it was set to 1.65v in bios, the actual voltage was lower than 1.65v. This time IBT passed with RAM at 2400.

I flipped the top-rear fan so that all 3 top fans are intake, but it really didn't seem to lower temps at all. My cooler intake is only 4C higher than the case intake, but the cpu is still getting toasty even with just 1.428v. However only IBT (stress testing) brings temp up this high (about 71C on core, with occasional spikes visible in the graph). Does not go that high gaming thank goodness tongue.gif

This time the average column is accurate in the first screen shot because I reset readings after the test had made a few passes.





Your motherboard seems to be running really cool. Be proud of that. But the cpu is cooking. If the air is heating up 4C in just the distance from the front of the case to the front of the cooler, then that hot air must be coming from the gpu. You need to blow that hot air back and down so your cpu can run at least 4C cooler. The air going into my cooler is at ambient temps. I tried some low noise low flow case fans and temps went up. They were not pushing the gpu heat down away from the cpu intake. New fans fixed that.

I have tried top rear case fans in intake, exhaust, and none, and none gives me the lowest temps. Methinks they disrupt air flow through the cooler. Keep experimenting with different combinations. Do you have all the pci slot covers removed?

I am trying to determine why this board offers no llc control, or if it does somewhere in the bios,and I'm just missing it?

All being said though, this was all totally expected @ $76, and for the money this is a good,but by no means great board.

Once I get a better cooler, and find a way too reduce the socket temp, I should be able to land a solid 4.8+, but for now, 4.6 @ 1.35v will have to do.

As for the 8300.... Hmmmm
Let's just say I finally understand what everyone has been saying in regards to coming from thuban...
On paper(benchmarks) my x6 @ 4.2ghz did just as well as this chip or better,even at 4.6 (except cinebench), but in real world usage, including gaming and everything else you actually do on a computer, this fx is noticeably superior.
The value at $99 is spectacular. I can guarantee that on a kitty or a crosshair, or maybe even a ud3, with an h80 or better cooler, this chip is definitely a 5ghz capable stud.

The more i read, the more i get convinced that this comes with the typical "Asrock 970 thin PCB". Mind you, i wasn't considering it really "thin", until i got my hands on the Giga 970 UD3P. Then i realised the difference... I don't think it's the chip generating the heat. I think it's the typical "Asrock socket overheat"...There is a 20C difference between the CPU socket temp and the core temp (package). This is typical behaviour in the 970 extreme3. I had also expressed my concern that Asrock would likely cut costs in the VRM with marginal mosfets... They went for the looks and features again... I am confident that the high temp you see is not VRM, but socket. On my extreme3 the VRMs stay below 60C, while the socket temps soars. Typical VRM behaviour too. With my power hungry FX6300 i couldn't run 4.3 stable. The VRMs couldn't do it. In the extreme3 the BIOS voice for LLC is simply "Load Line Calibration" and has only 3 modes: "Enabled, Disabled, Auto". Yours should have it too, let's hope with more options.

I know it's upsetting, but at the end, the socket temp, is a motherboard's problem, not a CPU's. The sensor is outside the CPU, in the socket and thus it suffers motherboard overheating, without the same going for the CPU itself. So, theoretically, you could just let the motherboard "cook" and raise your clock, if your core temp is still low.

More than getting a better cooler, i would also recommend, cooling the back side of the socket with a small fan, as this is the motherboard's problem and cooling the back will help a lot. This Asrock situation isn't funny anymore when you are overclocker. Before getting the Giga UD3P, i also thought my CPU coolers were all bad. I had Scythe Rasetsu, it had decent reviews, temps would run high even undervolted. I bought Xigmatek Balder, 1C difference. I was scratching my head. Others would run 8 cores overclocked with less capable coolers and have better temps, than my undervolted at stock 6300. I was scratching my head. But well, since i am not overclocker, i could live with it. Then i bought the Giga UD3P and my socket temp dropped 10C... Since then, i don't care too much anymore. I say "let them Asrocks cook"! I have many spares (inluding 1 Giga UD3P), i will probably buy one more and get over with it. I mean, on my Asrock 790 (same thin PCB), with a Scythe Katana3, i go over 50C in summer time with an undervolted stock Athlon II x2 (becomes like 45W). And other people use the same cooler to run 8320. Ridiculous. The only explanation, is that the thin PCB has less copper inside and/or overheats itself, magnifying the effect of heat in the socket where all the power draw concentrates. Don't blame the cooler, blame the board...

Of course, with more phases, the overheating is less crippling for the overclock. Still, from your description, it's still there and it's uncomfortable to just "let it cook", for psychological reasons, despite the CPU itself not really suffering...

EDIT: For temps confirmation, install Asrock AXTU, if it comes with your board. It's accurate. One word of caution thought. Despite being nice having it run at background all the time, in the 970 extreme3, it causes DPC latency to periodically spike (check with DPC latency Checker). And i suspect it's a software problem (bad programming). You can use Open Hardware Monitor if you want something always running on your systray.

EDIT2: In comparison, the Giga UD3P, when overclocked and at high voltage, you see that the package temp, starts to catch up to the socket temp, becoming at the end equal. So you stop because the CPU is really overheating.

Something else i noticed, is that the stock Asrock backplate, is murch more "closed type" compared to the Gigabyte. I don't know if it's the same backplate in the 970 Performance. Basically only 4 small holes allow air to cool the back of the socket. While in the Giga, there is a cut out in the center that exposes all the back side of the socket. I suspect this affects somewhat the cooling of the socket too.

IF the PCB of the 970 Performance isn't thin, then the only other explanation, is that they 've increased the amount of pastic/fiberglass, but the amount of copper is the same as in the 970 extreme3. So it still overheats, but it doesn't flex as easily.

I'll have it done for you guys some time this week.

I won't comment too much before then, because I am still learning both of them.

What I have found out, is that I underestimated the heat this chip would generate, even under mediocre voltage, and will definitely be looking for a cooler this week.

I will also add that I do not see how this board could possibly be rated to handle the 9590... It won't hold voltage stable well enough, and the vrm sink couldn't handle 1.5 volts even if it did.

I have added some fans that have helped quite a bit, but with hours of prime I see what looks to be either a socket, or VRM reading of over 80c. I have verified this in hwinfo also.

Hello Smith,

About the vdrop, have you messed with LLC?try those options, they should reduce it.

Vrm´s are hot by nature, most of them are rated +100º for a reason, you will see those kind of temps (80+) on most boards, diference being...the one you got have proper sensor´s and you get alarmed biggrin.gif

If they dont have sensor´s, you can only guess...just place a small fan into heatsink top and rest assured.

Again, for the price...great combo.

If you want, take some pictures of your bios, i can definitely help you with that OC.

Post them here or send me py PM, i´ll give you the proper settings.
